The problems in Samsung Galaxy Tab A is defective memory manager, segmentation of user, apps and memory. It keeps shutting down apps while in Linux this can be patched but in Samsung we need to wait. Only Samsung can repair the problem by improving the memory management of Samsung Android for Samsung galaxy tab A. I have no problems using Android 4.4.4 which have a superior but not effective user segmentation until in SM-113NU Android 10 has good userspace allocation but has problems in memory, apps and user segmentation. If this was in the US I could file a case against Samsung but I am the Philippines with poor consumer protection thus suffering from this problems.
