Rumor Reveals the Alleged Camera Specs for the Upcoming BlackBerry Mercury

We first started hearing rumors about the smartphone from BlackBerry that carried the codename Mercury back in June of last year. At the time, all we had to go on was that BlackBerry was working on three new Android devices and they carried the codenames Neon, Argon, and Mercury.

Neon and Argon have both been released since then (which we know of them now as the BlackBerry DTEK50 and the BlackBerry DTEK60. Then at the start of December rumors of actual details for the Mercury smartphone began to leak.
Such leaks suggested that it would come with a QWERTY style keyboard that BlackBerry is so well known for.

Other than a few tidbits about the device being made available on the Verizon Wireless network, we haven’t really heard too much about this upcoming smartphone since then. That is, until CES 2017 when they previewed a new smartphone with a QWERTY keyboard that we have been hearing about. Images of this smartphone showed up again in a Twitter post from the official BlackBerry Mobile account last week too.

So it seems BlackBerry currently has plans to launch this new smartphone next month at MWC 2017 in Barcelona. We know it will be manufactured by TCL (the same company who manufactured the DTEK50 and the DTEK60), but that’s about as much official information that we know right now. Interestingly enough though, a couple of new rumors claim to reveal the camera sensors that BlackBerry and TCL will be using for the upcoming smartphone.

If true, the device will be equipped with either a Samsung S5K4H8 or Omnivision OV8856 camera sensor on the front. This is an 8MP sensor with 1.12μm pixels that can shoot in 1080p at 30 frames per second. The same source has also revealed that it will be using the same camera sensor the Google Pixel uses on the back of the phone (we did a comprehensive breakdown of why this sensor is special). This is a 12MP Sony IMX378 sensor that can shoot 4K video. We’ll have to wait and see if BlackBerry’s post processing can match or beat what Google has in their Pixel phones, but the rumor suggests they’ll have the hardware to back it up.

Guide: Installing and Running a GNU/Linux Environment on Any Android Device

As many of you may well be aware, the Android operating system is powered by the Linux kernel underneath. Despite the fact that both Android and GNU/Linux are powered by the same kernel, the two operating systems are vastly different and run completely different types of programs.

Sometimes, however, the applications available on Android can feel a bit limited or underwhelming, especially when compared to their desktop counterparts. Fortunately, you can get a GNU/Linux environment up and running on any Android device, rooted or non-rooted. (The following instructions assume a non-rooted device.)

For those power users on Android tablets, or other Android devices that have large screens (or can plug into a bigger screen), the ability to run desktop Linux software can go a long way towards increasing the potential that an Android device has for productivity.


Setting Up GNU/Linux on Android

To get a GNU/Linux environment set up on your Android device, you only need to install two applications from the Google Play store: GNURoot Debian and XServer XSDL. After you do that, you will only need to run a small handful of Linux commands to complete the installation.

GNURoot Debian provides a Debian Linux environment that runs within the confines of the Android application sandbox. It accomplishes this by leveraging a piece of software called proot, a userspace re-implementation of Linux’s chroot functionality, which is used to run a guest Linux environment inside of a host environment. Chroot normally requires root access to function, but by using proot you can achieve similar functionality without needing root privileges.

GNURoot comes with a built-in terminal emulator for accessing its Debian Linux environment. This is sufficient for running command-line software, however, running graphical software requires an X server to be available as well. The X Window System was designed to have separate client and server components in order to provide more flexibility (a faster, more powerful UNIX mainframe could act as the client to X server instances running on much less powerful and less sophisticated terminals).

In this case, we will use a separate application, XServer XSDL, that GNURoot applications will connect to as clients. XServer XSDL is a complete X server implementation for Android powered by SDL that has many configurable options such as display resolution, font size, different types of mouse pointer behavior, and more.


Step-by-Step Guide

1. Install GNURoot Debian and XServer XSDL from the Play Store.

2. Run GNURoot Debian. The Debian Linux environment will unpack and initialize itself, which will take a few minutes. Eventually, you will be presented with a “root” shell. Don’t get misled by this – this is actually a fake root account that is still running within the confines of the Android application sandbox.

3. Run apt-get update and apt-get upgrade to ensure you have the most up-to-date packages available on your system. Apt-get is Debian’s package management system that you will use to install software into your Debian Linux environment.

4. Once you are up-to-date, it’s time to install a graphical environment. I recommend installing LXDE as it is simple and light-weight. (Remember, you’re running Debian with all the overhead of the Android operating system in the background, so it’s best to conserve as many resources as you can.) You can either do apt-get install lxde to install the desktop environment along with a full set of tools, or apt-get install lxde-core to only install the desktop environment itself.

5. Now that we have LXDE installed, let’s install a few more things to complete our Linux setup.

• XTerm – this provides access to the terminal while in a graphical environment
• Synaptic Package Manager – a graphical front-end to apt-get
• Pulseaudio – provides drivers for playing back audio

Run apt-get install xterm synaptic pulseaudio to install these utilities.

6. Finally, let’s get the graphical environment up and running. Start XServer XSDL and have it download the additional fonts. Eventually you will get to a blue screen with some white text – this means that the X server is running and waiting for a client to connect. Switch back to GNURoot and run the following two commands:

export DISPLAY=:0 PULSE_SERVER=tcp:127.0.0.1:4712
startlxde &

Then, switch to XServer XSDL and watch the LXDE desktop come up onto your screen.

I recommend putting the above two commands into a shell script so that you can easily restart LXDE if you close the session or if you need to restart your device.


Installing Linux Applications

Congrats! You’ve successfully gotten Debian Linux up and running on your Android device, but what good is running Linux without apps? Fortunately, you’ve got a massive repository of Linux applications at your fingertips just waiting to be downloaded. We’ll use the Synaptic Package Manager, which we installed earlier, to access this repository.

Click the “start” button at the lower-left hand corner, click Run, and then type synaptic. The Synaptic Package Manager will load. From here, simply press the Search button at the top and then type the name of the application you’d like to install. Once you’ve found an application, right click it and select “Mark for Installation”. When you are finished marking packages, click the Apply button at the top to start the installation. Uninstalling packages follows the same procedure, except by right-clicking and selecting “Mark for Removal” instead.

Of course, since this isn’t a real Linux installation but rather a Linux environment running on top of, and within the constraints of, Android, there are a couple of limitations to be aware of. Some applications will refuse to run or will crash, usually due to the fact that some resources that are usually exposed on GNU/Linux systems are kept hidden by Android. Also, if a regular Android app can’t do something, then usually a Linux application running within Android can’t as well, so you won’t be able to perform tasks such as partitioning hard drives. Lastly, games requiring hardware acceleration will not work. Most standard everyday apps, however, will run just fine. Some examples include Firefox, LibreOffice, GIMP, Eclipse, and simple games like PySol.


I hope that you find this tutorial useful. While I personally performed these steps on my Google Pixel C, you can do this on most Android devices. Preferably on a tablet device with access to keyboard and mouse peripherals, of course. If you already run a GNU/Linux distribution on your Android device, let us know what you are using it for below!

Rovo89: Update on Development of Xposed for Nougat

New Leak Shows the LG Watch Style In Silver and Rose Gold, may Start at $249

We’ve known for a while now that LG is likely working on two new Android Wear watches allegedly called the LG Watch Style and the Watch Sport. While we have already seen images of both the LG Watch Style and Watch Sport, those were unfortunately quite low resolution renders. Now, a new leak from  Evan Blass (@evleaks) has gives us a clearer picture (literally) of what LG’s upcoming Android Wear smartwatch, the Watch Style, may look like.

The image of the LG Watch Style shared by Evan Blass match those leaked by TechnoBuffalo a few day ago.

As you can see in the image, the renders show the LG Watch Style in both silver and rose gold colors with sporting leather straps. In terms of design, the Watch Style appears to be a classic fashion watch unlike its counterpart, the Watch Sport, which is said to be the bigger of two watches and will likely feature heart rate sensor, GPS, and cellular connectivity.

The LG Watch Style and LG Watch Sport are expected to launch at Google’s platform event on February 9 where Google is expected to detail their much awaited Android Wear 2.0 update as well. Both watches are said to be manufactured by LG and Google in a Nexus-style collaboration, meaning the hardware will be handled by LG with Google providing the software and any future updates.

If previous rumors are to believed, the LG Watch Style will feature a 1.2″ 360×360 resolution AMOLED screen, 240mAh battery, 512 MBs of RAM and will have Bluetooth (no cellular radio) for connectivity. Furthermore, according to a source speaking with AndroidPolice, the Watch Style will launch at a price point of $249. Although for more concrete details, we will have to wait for the official announcement.

A Guide to Editing RAW Photography — Get the Most out of Your Smartphone’s Camera

­­

After exploring the RAW capabilities of my OnePlus 3T and Sony NEX-5 cameras, an array of readers responded with questions and comments on RAW photography and their experiences. Many expressed the desire to better learn how to edit photography and particularly how to deal with RAW file formats on both mobile devices and desktop operating systems, and I was thrilled to see such a willingness to engage in something new like RAW photography. I was also deeply happy to have several readers relate to me that I had inspired them to explore photography in general once again or even for the first time –it can come as a surprise to many that the device in their pockets is often their best choice for exploring. In light of these discoveries, my hope is that some assistance for those struggling to begin will continue to encourage those interested in photography, RAW or not, to persevere.

Remembering back to my first forays into photography and editing, I was lucky enough to ease into the prospect bit by bit, beginning with something as simple as the built-in editor in my HTC Incredible 2’s gallery app. If I am remembering correctly, I stumbled upon Adobe Lightroom as an app for my iPad 3, which became my go-to editing device until I built my first desktop PC. Over the course of a month or so, I essentially explored each slider and option until I was relatively familiar with the program. I can easily recommend this to anyone with a lot of patience and curiosity, as you will inevitably find your own preferences along the way while also learning to use a powerful editing suite independently.

Nevertheless, having someone to guide you through the very first steps of editing and break down the menacing façade that Lightroom and other editors can present the user is of course extremely useful. I will attempt to be that guide!


First Steps

As several curious and intrepid readers soon discovered, shooting in RAW is not necessarily the most intuitive experience, especially once one goes to find or edit the RAW format files they have produced. As RAW files, especially DNGs, are innately not images straight out of camera, nearly all gallery apps simply will not register that they exist, both on mobile and desktop operating systems. This is not a criticism of gallery apps, but rather an unavoidable reality of RAW formats. As such, you will want to either install one of a handful of free RAW file managers, or bite the bullet and pay for something like Photo Mate R3 (~$8). Adobe Lightroom for mobile devices is likely your absolute best option, being free and well-designed.

For those of you looking for something a bit different, Photo Mate R3 is a fully-fledged mobile editor with almost all of the granular controls that Lightroom and other desktop editors offer. It also provides a gallery function with an array of sorting options, allowing the viewer to, say, selectively view only RAW format images and preview their thumbnails. The only major downside I noted is a lack of granular noise reduction controls of the sort that Lightroom offers. RAW files express all the noise the camera generates (a lot) and can appear rather off-putting if one does not first consider that lossy formats like JPEGs include some often heavy-handed noise reduction that occurs as the RAW data is converted and compressed. RAW lets you decide how much noise reduction is needed, potentially preventing the overly-soft images that smartphone cameras are often infamous for.

If you have access to a computer, there are numerous free options for editing RAW photography like GIMP and Rawtherapee. Rawtherapee offers a genuinely impressive program that is solely dedicated to editing RAW format images and is easy to recommend. There is also Google’s free Nik editing suite, which offers a dedicated program for noise reduction to assist those on a budget who can’t stand noise but would prefer to keep their editing workflow as mobile as possible.

A brief glance at Rawtherapee 5.0’s interface (Rawtherapee).

For those of you willing to fork over the cash, however, my one true photo editing love has always been Adobe Lightroom. It may be an irrational attachment to the program I am simply most familiar with, but I find that it offers a wonderful, intuitive interface and an almost invaluable organizational aspect that allows you to comfortably back up a database of around 40+ GB of edited photos while still retaining exact change histories and the original files. While next to nothing compared to professional photographers or very serious amateurs, I’ve taken and edited thousands of photos in the 5 years I’ve been active, and have a history of almost every single one in my Lightroom library.

A small snippet of my primary Lightroom catalog. My edited photos can be found at my Flickr and VSCO accounts.

While verifying that my understanding of Adobe Lightroom mobile was accurate, I discovered that free users can in fact edit RAW formats without a CC subscription! While the free version loses a number of features, it is still well-featured and includes several noise reduction filters, albeit without the ability to control it (aside from picking low, medium, and high reduction options). Like Photo Mate R3, the Lightroom app offers a useful gallery feature that lets you preview RAW thumbnails and filter out non-RAW images. This app is definitely my recommendation for those looking for a slick, user-friendly solution. While experienced users may find some improved utility in Photo Mate R3’s broader range of options, Lightroom will be more than enough for most mobile editors. This article provides a great overview of the app and its RAW editing features.


General Tips and Suggestions for Editing Photography

While providing granular tutorials for each of the applications mentioned above is a bit beyond the scope of this article, what I can do is explain some of the more common options you will have at your disposal, regardless of which one you choose to adopt. I will be using the desktop version of Adobe Lightroom (5.4) to demonstrate these features. After the process of finding your RAW files (usually .DNGs for mobile devices) and importing them into your app of choice, you will be presented with several options. Generally speaking, these options will be intended to modify the tone (exposure/lighting), white balance, and color in your photos.

Some of the most useful and intuitive methods of editing in Lightroom are relatively unique to it and even then only in the desktop app. My favorite ways to modify a photo’s tone are through the histogram (the graph at the top of the screenshot below), which allows you to click on one of five sections (blacks, shadows, exposure, whites, highlights) and drag them left or right to reduce or increase the prevalence of that specific light type. The tone curve, found below the Basic section, can also be dragged about in a similar fashion, but is generally only needed for slightly modifying a nearly-complete image or recovering detail in an image that was drastically over- or underexposed. This can all generally also be done with the sliders you can see on the right, but this takes somewhat longer and is also not nearly as fun! A great exploration of the utility of histograms and how to read them can be found here.

Two images and their related histograms.

Traveling down the options in the menu pictured below, we begin with ‘WB’ or white balance. This is used to improve accuracy of the color representation in photos, accomplished by modifying the temperature and tint in order to direct the picture towards your preferred outcome, which may include fixing imperfect white balancing in camera. In desktop and mobile Lightroom, you have the option of selecting the eye dropper, which effectively auto-corrects white balance once you direct it to a point on your photo that you know should be a neutral grey or white.

Tone settings come next, beginning with options for exposure and contrast. Exposure modifies the global brightness unselectively. Contrast further darkens darker areas of the image and brightens lighter areas. After these more heavy-handed options, there are more precise controls that can also be controlled through the histogram on top, as I previously explained. The highlights slider will modify only the brightest sections of the image, allowing you to tame overexposed images (you may have seen or heard the term “blown highlights”). Shadows, on the opposite hand, can help recover lost detail in dark areas of images. Lastly, Whites and Blacks intuitively allow pixels leaning towards white or black to be made brighter or darker. Attentive readers may notice a theme so far of combinations of controls that offer large changes (whites, blacks) with controls that offer more detailed modifications to smaller parts of the image (highlights, shadows).

Continuing this trend, Clarity is effectively a method of only adding contrast to mid-tones (mid meaning middle of the histogram). In doing so, the Clarity slider can give the benefit of added contrast while preventing the noise or grain (and often an uglier image) that can come overuse of the global Contrast slider. This option is generally unique to Lightroom, but it can be partially replicated by experimenting with white and black levels (increased contrast would mean darker blacks and brighter whites). This method won’t add edge detail like Clarity, but it will more subtly add contrast.

Saturation and Vibrance are the last basic settings one may frequently want to use. Saturation is the color equivalent of Exposure, allowing the user to globally deepen or lighten all colors in an image. Vibrance helps to avoid the downfall of global saturation changes by only adjusting the least (+) or most (-) saturated colors.

Finally, there are several more complex and granular settings that can be found in Lightroom and other desktop editing suites. Something I often find myself using is detailed saturation, hue, and luminance control (on the right), giving me the ability to, say, recover oversaturated blues or greens, or better express the yellows and oranges in a sunset photo with subpar white balance. The Detail section (on the left) is where noise reduction and sharpening settings can be found, very useful options to have when editing RAW files. Lightroom helpfully provides a small window with a highly magnified view, which makes it considerably easier to avoid introducing ugly artifacts or obscuring detail when modifying sharpness and adding noise reduction.

                     


Practice, Practice, and More Practice!

As a tried-and-true trope of many a guide, my best suggestion for those just beginning to stretch their photography-editing legs is to not give up and keep trying. Mistakes will be made and modifications will be overdone, but in time you will begin to develop a more instinctive understanding of editing and likely come into a style and workflow of your own. Mine has taken many years to develop and I clearly remember struggling at first, as well as taking a look at photos I’d edited years ago only to be aghast at the aesthetic decisions of past-me. I’m still learning more than 5 years in, and I even managed to learn a couple new things about editing photos in the process of writing this. In all its breadth, photography is essentially an activity with constant opportunity for learning, and rather than being daunting, it simply makes it that much more exciting and rewarding.

Amidst the humbling response my previous article received, multiple readers shared some of their own impressive smartphone photography and blew me away. If you have taken any photos with your phone that you are proud and would like to share, feel free to post them in the comments below this article, as well as on its corresponding Facebook posts or tweets. An upcoming article in this series will include a collection of user-submitted photography, so don’t miss out!

Also ahead will be a brief tutorial on how to use the manual mode available on many modern smartphone cameras in order to best take advantage of their capabilities.

Moto G5 Passes Through the FCC, Likely to be Unveiled at MWC 2017

As we inch closer to one of the hottest events globally for smartphones in the form of the Mobile World Congress 2017, we witness some more phones getting leaked on the way. This time, we get new information on the Moto G5, which has passed through the FCC.

The FCC filing does not reveal a whole lot of spec info on the Moto G5, but it does let us know that the device will be coming with a 3,000 mAh battery. This phone will also support a form of quick charging, likely called Turbo Charging based on past naming conventions. This is inferred from the adapter specifications listed, as the included charging adapter is capable of outputting 14.4W at 9V/1.6A, 12V/1.2A and 5V/1.6A. This is a nice change for the non-Plus variant, as only the Moto G4 Plus included the Turbo Charger in the box while the Moto G4 came with a puny 5V/0.55A charging brick.

The other notable point in the FCC filing is the inclusion of NFC. Previously, the main Moto G4 lineup still did not come with NFC capabilities, although the “Play” variants did sport them. Adding NFC to the base model implies that all the other variants will possess this.

Motorola does have an event planned for Mobile World Congress on 26th February 2017, where the Moto G5 and the Moto G5 Plus are likely to be unveiled. As for specs, the Moto G5 and G5 Plus are likely to stick with a 5.5″ display and switch to the Qualcomm Snapdragon 625 SoC. Leaked images of the G5 Plus have been floating around, but we will have to wait on for more concrete information.

What are your thoughts on the Motorola Moto G5 and Moto G5 Plus so far? Let us know in the comments below!
