Hey LTT people, long time no see.
I've had a OnePlus 6 for a while, and took it on vacation with me recently. While on vacation I briefly dropped in the water (while it was on). I quickly took it out, and turned the phone off. I turned it back on later that day, and it was fine until it started boot looping. It then boot looped for while, and I turned it off. I turned it back on a few days later, nothing. I turned it back on two weeks later, and it worked! Sense then it has gone through phases of working and of boot looping, but most of the time the cycle went like this: Turn it on, it turns on, crashes after a while, boot loops if I try to turn it back on, I wait a while, I turn it back on without problem, repeat. This happened for about a month until recently, with the previously mentioned cycle lasting different amounts of time, but consistently. What I mean by this is sometimes it wouldn't crash for a day, and if that happens the next few days it would only crash daily. Sometimes it would crash 30 seconds after turning it on, and would do that every time it was turned on for a while. Anyways, It seemingly finally really died. It still boot loops, but never even makes it to the sign in screen anymore.
If anyone has any ideas on what specifically could be causing that problem (or narrowing down what could be causing it) please let me know. I've contemplated taking it to a repair shop, but I figure its not too common of a phone and chances are they won't be all that helpful if I don't already know the problem.
Thanks so much for you help.
