I have a Samsung Galaxy S6 in which on Android 6, the menu buttons (backspace and application) were flashing like a strobe, the phone worked (buttons too), while the touch seemed to be slightly lagging and draining the battery faster. This has not always happened but often. I uploaded a new (4 file) Android 7 and now the buttons do not work at all, but sometimes they light up, the rest remain unchanged, i.e. how light touch lag and battery discharge. In addition, the phone works normally and undergoes all tests etc.
I looked for it on the internet and found threads on xda and at & t but unfortunately no solution ..

Maybe someone can do something about it?
