bro

I have a signal problem with my fone if i take the covers off its ok but wen i put it back on after a day or or half a day the signal goes zero and the signal is dead

can u give me some advice i opened it several times before and changed the back casing it seems better but the problem still persists, i think its because of the constant beating the fone gets from falling...

I think there is something loose
can you help me out?
