Loudspeaker sometimes works sometimes doesn't
Hi!
I received an iPhone 5s for free so I can use it as my backup device, it’s really cracked on the front and the touchscreen doesn’t work on the center, but that’s not why I’m here.
My question is, sometimes, the sound cuts out of the loudspeaker, and if you put your ear on the loudspeaker grill, you can still hear the sounds, but they are barely audible, if I beat the phone on the back a few times, the sound comes back to normal, but after some time the same thing happens, there are very rare occasions on where it comes back by itself.
Could this possibly be an loudspeaker issue?
I still have never opened an iPhone, so I have zero experience.
Thanks.
Es esta una buena pregunta?
