This thread will be official thread for all Nexus 5 advanced (developers) users which got affected by this issue.
First of all please do not spam and post useless information about how you also have memory leak and asking how to fix it. Post only useful stuff, like logcat and such stuff which can help google developers solve this annoying bug.
I reported this issue to google with good amount of information and I am willing to keep that report updated with latest highly detailed information, link:
Please star this so we can get quick attention from google and assign it as high priority bug. You can star it by clicking on star top-left on the page.
- For users which seem not to have this issue please Download Farm Heroes Saga from play store. Run it until game loads, then remove it from multitasking menu completely and then run game until it loads, remove it from multitasking menu again and do that about 10-15 times. If your ram doesn't go up to 900 and higher please post logcat if you know how to and also screenshot of default memory and cached memory.
