First thing : sorry for my low level in english , I'm doing my best ...
It's my first post , sorry if i'm making some mistakes
Let's go :
Picture to make evrything clear :
Bootlocker: I don't know but this devise is totaly stock
=>Problem : my phone is runing slow
What i had do befor: nothing , just using it to play a game (drag racing), to contact my friends, to wake up the morning ...
=>What i had try to solve the problem : clearing the cache, restaring, unistalling some apps that have some backround tasks ( facebook messenger, Kakaotalk ...), using some apps like clean master, also removing the SD (8gb) ... But the same problem , once i open something it becomes laggy
=>What I need : I'm really a "I-Don'T-Know-Anything", so if someone has any idea please
Thanks for reading
