With the addition of the Galaxy S6 and the Galaxy S6 Edge in Samsung's smartphone lineup, Samsung has pushed the envelope ever further with improved features and functionality in more than a few areas compared with previous iterations in the Galaxy S series of devices. One of these is most notably the use of metal and glass for the material makeups of the body design, while others like the improved camera and wider f1.9 aperture for better low-light images seem to be delighting customers as well. Early on though it seems that some customers have been experiencing issues with memory management on both new devices, and according to Forbes, Samsung has openly admitted to the problem and confirmed the existence of the issue through their UK Facebook page.
Memory leak issues have been a problem for many Nexus devices with the coming of Android Lollipop, and it's a problem that still hangs around for some users even after a couple of updates. Google has also openly admitted to the issue being there and has been working to correct the problem. For those that are unaware, the memory leak is causing a slow down of apps and overall performance management, and is even causing some applications to crash when attempting to open them up. This is because the RAM isn't being freed up after applications are no longer in use and opening apps anew is resulting in grabbing additional unused portions of RAM.
Since the devices only have so much RAM to disperse, eventually it's logical for issues like app crashing and slowdowns to happen. While this isn't happening to every single Galaxy S6 and Galaxy S6 Edge owner, there were apparently enough users having the issue that it required a confirmation by Samsung attesting to the existence of the problem. While it isn't exactly certain that Lollipop is the cause, given the other types of devices on various versions of Lollipop having the memory management issues, this is the most likely scenario. Samsung is said to have an update in the works which is supposed to address these memory problems with a fix, but for now you can either close all apps from the recents menu which doesn't guarantee you'll free up all the RAM being locked up by unused apps, or you could reboot the device. It's merely a temporary solution, but it's better than no solution at all. As for the fix that is to head out to devices in the near future, Samsung states that "Micro-updates are in the process of being rolled out to correct issues relating to device performance and stability… Keep checking for these on your device via Settings>About device>Software update>Update now." If you're having these issues with either new Samsung device, a resolve should be on the way soon.
