Last night I dropped my phone in my drink for a solid 30 - 60 seconds. Long story about how and why that happened. I couldn't turn it off immediately since there's no removable battery and the screen display went black (I later found out the display cable/connector was right around the area it was submerged in) but it was still playing Spotify. I unplugged and attempted to suck out all the soda that I could and ran my vehicle's heat on it at max temp for a few minutes since I was driving and couldn't stop or do anything else.

Before bed I left my phone in a bag of rice completely taken apart. Back off, motherboard separated, and battery outside of the bag. The device was only submerged maybe 50% of the way. I've woken up and tried testing it out and the screen turns on! However, when it boots up fully the screen goes black. If I sit the phone face down and pick it up, it will display the time, date, and a WhatsApp error saying the date/time is off. If I touch the screen or press the power button it will instantly fade to black. The entire time the phone is turning on, the display is fully on and nothing is wrong with it except for when it fully boots into OS. Any ideas?
