1 Unexpected working on speaker
I purchased a second-hand iPhone 11 and replaced the screen and the battery. I’m not certain if this started after the replacements, but when someone calls me, the ringtone plays, then stops after a while, starts over, stutters, and so on. Sometimes, there is no sound from the phone at all. Similar stuttering issues also occur within the ringtone selection menu. Could there be an issue with the battery? I have already tried a clean install, but that did not resolve the problem.
