Respuesta a "I can’t hear people on my phone unless it’s on speaker."Can you hear at all? If you can hear but at a very low volume, your ear speaker grill is probably covered with dirt and grime. You can gently wipe it with an alcohol pad, then brush the debris off with a hard bristle toothbrush — don’t use the air spray because that would just push the dirt inside, clogging it even more. The proper way to clear out the blockage is to open the phone up then take a part the ear speaker and the flex, and blow away the dirt from the grill (you can use the air spray from outside in or inside out .) Be sure to hold the screen up at the light to check that the grill is clear. If you cannot hear at all, it is most likely that your front ear speaker/camera flex is bad. You can order a new one and replace it.
Respuesta a "My iPhone 6 shows no service or searching..."I have the same problem. And, like most folks here, I have tried pretty much everything from changing the charging dock to moving the mainboard to another working frame. The phone would work for a few days then mysteriously goes into the searching mode, then eventually no service. The software is up to date; the phone has been fully and network reset so many times but the problem persists. The temporary solution I have found is that whenever the phone loses the connection, I would open the phone up and unplug the charging dock connector and wait a few minutes before reconnecting it, then the phone would work again. Not a very ideal fix but it works.
