I Just Wanted Clean HDMI on a Note 10+ (Telephoto)

by

This week's obsession came when I decided I wanted to repurpose my recently repaired Samsung Galaxy Note S10+ as an overhead camera for the workbench. Its image sensors vastly outperform any ordinary webcam, including my $200 Razer Kio Pro. The distance from my homemade ceiling mount to the workbench tabletop makes the 2x optical zoom of the Note 10+ a perfect fit. But in all the years I owned this phone, I never realized that only the native Samsung Camera app allowed use of its telephoto lens. All other applications, free or paid, are only able to interface with the front-facing cameras, wide angle and standard 1x back lens.

Unlucky for me but fortunately for everyone with slightly newer models, Samsung finally introduced clean HDMI out with their native Samsung Camera app as part of the One UI 5.0 release. Note 10+ and lower are ineligible for the upgrade. My Note 10+ is currently running One UI 4.1 and Android OS 12 with kernel 4.14, all of which are pretty much end-of-life for the phone beyond security patches. Read Full Article

SAMSUNG Remote Test Lab: Test Android Apps on Real Devices for Free

by

For the past couple of months, I've been working on a much-delayed update to my Android application Scribblify.  The original Android version was released back in early 2013 and hadn't been updated on Google Play since then. Although it paled in comparison to the iOS counterpart, the first Android version still received positive reviews and was downloaded 200,000 times. Having released a major 4.0 update to the iOS version earlier this year, it was time to bring the Android version up-to-speed.

One of the greater challenges experienced with Android development occurs when it comes time to test. I previously wrote about the increasingly fragmented iOS platform, but even with a handful of different iOS devices sporting different resolutions and technical specs, nothing quite compares to Android device dispersion. In my updated Android app, for instance, I support all Android devices from API Level 15 (Android 4.0.3) up. According to Google Play, this makes the app compatible with 9,098 Google-certified devices. This list encompasses at least four years of devices including phones, tablets, phablets and more. Understandably, with such a large range of devices comes an equally large range of technical specs. Read Full Article

Using Bluestacks for Fast Android Emulation

by

Testing Android applications on PC or Mac without a physical device can be quite a burden. The configurable Android virtual machines in Eclipse/Android Studio are notably sluggish and don't work well with many third party frameworks, especially those powered by C++. If your development machine has Intel-based hardware you can accelerate the emulation process by using Intel® HAXM technology, but AMD users are not yet so lucky.

The fastest and easiest way I've found to test Android applications is via the BlueStacks app player. BlueStacks is a free, ad-supported product for PC and Mac that enables you to download and run Android applications from your PC, as if using an Android device itself. BlueStacks isn't the only product on the market of its kind, but it does boast higher compatibility and a greater feature set than the competitors. According to BlueStack's feature chart, it supports up to 96% of all apps and 86% of all games on the Android market. Furthermore, BlueStacks offers streamlined emulation of the Android device's camera, microphone, multitouch and more which makes it ideal for testing in-development apps. Read Full Article

Verizon Ellipsis 7 (QMV7A) Development Woes

by

A couple years  ago I decided to switch my cellphone provider.  On Black Friday, Verizon Wireless offered a "free tablet" deal upon activation.  It was the same sort of persuasive deal many carriers offer throughout the year, almost always requiring a two-year activation commitment for the tablet itself, on top of the regular cellphone contract.  The tablet was their own branded Ellipsis QMV7A 7" (by Quanta) with so-so hardware specs. (I had, in fact, just been gifted the all new 7" Kindle Fire HDX a week prior as part of an Amazon promotion, and the QMV7A was light-years behind it in resolution, technical specs and overall build quality.)

As I sat waiting for hours on end for the recently hired Verizon staff to activate my service, I checked the going rate of the QMV7A tablet online; $130 at most. Verizon promoted it as a $250 tablet, and with the two-year contract this "free" tablet would actually cost me about that much given the $10+ a month service charge.  The data plan was shared with the main phone as well, so there was no extra data allowance.  Still, I saw some value in owning another Android tablet for development purposes and agreed to the commitment.
