investigating and given with a file in the system that I did not like. I did not understand it I opened it and I saw some very strange lines. Well, yes, true. removed from the system with root and the phone now manages the ram better and the battery holds more .. the applications open faster and the system now seems more stable than before.

the file is in system/ etc/ lmk.oom.level
I decided to eliminate it and the big surprise came when I reset the phone. what I do not know is if in flyme 7 it is or in other phones too.I encourage you to eliminate it from the system that you will notice a 100 %% better
