Can I clean the Ambient Light Sensor with ispropryl?
Coworker brought in his wife’s iPhone 12 that was having issues with the screen being super dim randomly after it boots. Figure it’s probably the ambient light sensor and sure enough find the tiniest spot of patina on one of the contact points on the back of the display where a drop of water got in (trying to explain to people that’s enough to kill something is a struggle though)
I’m not interested in fussing around with transferring components over to a new flex to keep Face ID (because reasons) so he’s just getting a Self Repair display and I’m going to do it for him since his wife wants to make sure Face ID stays intact.
In the mean time. The ALS works sometimes, if it feels like it. I’m figuring there’s some corrosion or something somewhere I can’t see because my microscope is at home. How risky is it to try and clean the ALS up with some isopropyl. Is that going to murder it more?
