Réponse à : « Phone keeps crashing after repair job. »To be honest, your problem isn't exactly the repairs. I would say it's literally the phone itself. It's probably trying to fix itself, as crazy as it sounds. Sometimes, a phone freezes because it needs to get rid of some things that slow it down. And crashes are typical. As you know as Apple moves further along in makes and models they forget about later models. Such as the fact that iPhone 4 no longer updates. Maybe the update is essential.
