• Probably not your problem, but my completely different phone (oneplus 7 pro)has been pretty solid. But, lint and dust gathered into the port, making some of the plugs extremely loose to the point it would fall out from the weight of the cable… I took a needle and scraped out the compacted lint at the bottom. (avoiding touching the middle thing in the port. Good as new afterwards, even the one cable I’ve been using with the phone since 2019 which is pretty loose after use now, still sits without problems when moving the phone around.

    But I’d definitely suggest cleaning it out if you haven’t. Even the small specs you get out makes a big difference. My powerbank came wouldn’t stay in, after cleaning it’s more well behaved. But there’s a clear difference in USB-c plugs and how they fit phones.
