J'ai récemment commencé à avoir des problèmes avec mon samsung galaxy s5. Pour la nuit, je branche mon cellulaire pour le faire recharger. Le matin, l'écran est noire et ne s'allume pas mais les touches dans le bas s'illumine. J'ai essayé un hard reset mais le problème persiste. Apparament je ne suis pas le seul à avoir ce genre de problème: Problem: When phone is off, usually overnight, I charge my phone at night, in the morning when I try to use the phone (not turn on, it’s always on) the screen flickers from black (off) to a yellow colour. As it if it was trying to turn on and goes back to black (off). I do this several times until I have to remove the battery and turn it back on. Then it works with no problem. When I have low battery 5% the screen begins to flicker brightness intensity and there is a green line at the bottom of the screen. If I charge the phone like this, the green line does not disappear until I restart the phone. Previous android version when in monochromatic battery save mode the green line would appear. Please recommend if a change of phone is needed. The phone is 11 months since activated
