I owned my iPhone 14 Pro for around 2 weeks when the screen started randomly blacking out while I was in the middle of using it. Initially it did it mostly when I was reading something in landscape mode, then it was truly random. Usually, all it took to get my screen responsive again was pressing the sleep button twice slowly. As such, I didn't think this was the BSOD problem, though I couldn't find any other search results online that mentioned the screen going black temporarily.
Yesterday, for the first time, the screen went black and was unresponsive (it wouldn't come back after pressing the sleep button 2 times slowly). I tried the trick many people mentioned for a forced restart (up volume, down volume, hold the sleep button) and it didn't work (I held the sleep button pressed for a while and nothing happened). After about 15 minutes, the screen became responsive again. I immediately did a backup.
Today, I went to Best Buy to get the phone exchanged (I was still within the exchange period). The phone started acting up again while I was there. Thankfully it was on long enough for me to turn off Find My iPhone and for the salesperson to get my IMEI ID off the phone before it became unresponsive for good! They had a Geek Squad person try to do a force restart but he wasn't successful. We kept at it during the whole exchange process (I was there for more than an hour) but it never came back on. FWIW, I had the latest iOS installed (16.1.2 at the time) and there was plenty of storage space available.
Hopefully the glitch was with the first phone and the 2nd won't have this issue. I was lucky in many ways with this one since I was still within the exchange period and my local Best Buy still had a few iPhone 14 Pro's in stock (my local Verizon store has been out of stock for a while).
