Was a OnePlus user for years. Had the original device, the 3, 5 and the 7 pro since launch. I replaced the battery in my 7 pro and put lineage on it just to keep it going.

My idiot brain jumped off a boat last week with it in my pocket and I assumed I would just get the new one. But no unlockable bootloader means I need to look elsewhere.

Not a doctor, and you should definitely talk to one before trying it, but I have found Eno to be remarkable in solving gaseous bloating.
