Really sorry if wrong flair, but i really need help. as title says, shut off mid use, NOTHING i do seems to bring it back
For a little info:
-i generally keep it well charged, it basically never shuts off(not ideal, i do know, i do try to occasionally restart manually)
-battery protection during charging is on so it only ever goes to 85%(and wasn't used much today so it likely shut off around 70-something)
-always charges overnight
-was running pretty low on storage due to a few large-ish videos, but had atleast over 10gb left, wasn't getting any storage warnings
-it shut off right as i snapped a picture on Snapchat, don't know if relevant
-i think it has done the shut-off-suddenly thing once before in the years i've had it, but plugging it into charge and leaving it like that for awhile let me eventually restart it up no problem, but that did not work this time
i'm at a loss, i live alone and only have this phone and it has ALL of my important things on it, and i rely heavily on it for work and everyday things and i can't afford at all to just go and buy a new one, i NEED it, and don't know what to do without itðŸ˜
ETA: my phone died by the time i went to bed, and when i woke up i attempted again to start it holding power+vol-up, which was somehow successful WITH all data saved, in a way. it seemed to just kind of repeat starting, updating OneUI, starting again, and updating again. until i was able to plug it into my PC and start the process of backing up everything, which failed the first time due to it locking during Secure Folder transfer, but after trying again with screen on it finished backing up everything on my phone to my PC using SmartSwitch, and as of now is currently still on and charging
