[BUG-Problem]H-815 Stock keyboard & notification led

Hello everyone, I recently purchased a "G4" and I noticed two annoying problems, the keyboard appears with the handbrake with any app, even turning off the tips of the words, I solved using another keyboard although there have been a little bad, with all my smartphone I always used keyboards stock without problems.
As for the problem of the led I believe that will not work with third-party apps and here I turn to you because I do not know how to solve.
Thanks.
