No reboots,good battery life,solid warming,no issues yet .
You can use Rootjoy as your official ROM flashing solution.Always make a full backup,before you start the flashing process.!
Only for Offical ROM update /Don't use this if you have custom ROM installed /
1.Download Rootjoy
2.Plug your Phone and allow connection
3.Create a full backup of your phone
4.Flash your mobile device
***Warning ***
Your device data wil be deleted permanently.Do it at your own risk !
***If you have custom ROM you can get an error that your mobile doesn't supported anymore***
If you are not familiar with flashing process please find previous ROM's posts, where you can find more detailed description about the "how to ",and also you can find answers in the comments for the upcoming issues.

rear speaker audio tuning:
open mobile uncle tool –>engineering mode (MTK)—>Hardware testing/audio—>loudspeaker mode–>> type:media–>set level 0=120 (level1=130,level2=140..etc ) increase the number on different levels as you wish, till max level 14 =230
