Hello, I dropped my phone and it turned off and I could not get it to post, so i plugged it into charger and it took so long to boot (and then started bootlooping) that I unplugged it and it went black instantly, I tried connecting it to computer and it did not recognize it. I though that the battery connector is unplugged, so I opened the phone by the iFixit manual and it still does not work (still bootloops). Sometimes I get red screen. What should I do? I will bring it to authorised repair shop as soon as possible.
You may want to try disconnecting the Front Camera/Sensor flex to see if that helps. A damaged proximity sensor, which could have been damaged by the fall, could be causing this issue. Follow this guide to disconnect it and if it solves the problem, simply order a new one and replace.
