This memory manager really helps with the RAM usage on our device. I downloaded it and set it to aggressive and noticed a good deal of difference. Notes: 1. Device must be rooted. 2. Works good on other phone however not all phones are supported. Link: https://play.google.com/store/apps/...wyLDEsImNvbS5saW0uYW5kcm9pZC5hdXRvbWVtbWFuIl0.
