Poor memory management dogs Samsung Galaxy S6, S6 Edge http://revealedtech.com/computer-system/poor-memory-management-dogs-samsung-galaxy-s6-s6-edge/

Samsung Galaxy S6 Charging

When Samsung unveiled the Galaxy S6 and S6 Edge, it clearly meant to push the envelope. The new devices run Android 5.0.2, pack a brand-new 14nm processor, utilize LPDDR4, and feature an optional curved screen with a 2560×1440 resolution. Unfortunately, Samsung’s memory manager appears to have pushed the envelope a bit too far.

Reports are rolling in that the platform suffers from two memory-related problems. First, the S6 and S6 Edge appear to kill background processes extremely aggressively, even when the end-user has scarcely opened any additional programs. The issue can be seen on the video below. In the first part of the video, the author showcases a benchmark run between three devices — the Samsung Galaxy S6, the HTC One M9, and the iPhone 6. The Samsung Galaxy S6 wins the initial run, in which all of the test applications are loaded from scratch.

We’ve skipped ahead to the second run, because this is where the results get interesting. Both the HTC One and the iPhone 6 beat the Samsung Galaxy S6 on a second trip through the benchmarks because the Galaxy S6 is reloading every program from scratch, while the other two devices have kept the data cached in RAM.

Users are reporting that this is a problem, even in day-to-day usage, with Chrome being killed as soon as you open a different application. One reader has posted screenshots of his own device’s app use to XDA-Developers, and the image appears to show that system and applications are still chewing ferocious amounts of memory — Facebook’s own app plus Messenger is eating 360MB of RAM.

Still, on a device with 3GB of RAM and 571MB reported free, other applications should still have enough room to breathe. While Facebook doesn’t look real great in the screenshot, there should still be enough room for Chrome or other browsers and applications to cache their information — especially if their default states are saved in the 2GB footprint shown above.

Android Lollipop does suffer from a memory leak issue, but this problem doesn’t appear to be related to that one. Neither Samsung or Google have commented yet, so it’s impossible to tell how widespread the error is, or whether or not there’s a timetable for a fix. If you purchased a Galaxy S6 or S6 Edge, have you noticed any issues with frequent app shutdowns and long load times when switching between applications? Please let us know in the comments.
