While replacing my screen the proximity light sensor ribbon cable broke. Thinking not a big deal I’ll just have a feature I can’t use. My phone would turn on work for a few minutes then freeze, give the pink screen of death and reboot. This article helped me understand what was going on and the linked replacement part was reasonably priced and arrived quickly. Thankfully the new part resolved my issue as the stores near me said the only fix was an entirely new phone.
