I have the S22 Ultra which was plagued with poor connectivity problems early on, not just wifi it is any connections I.e wifi, Bluetooth, mobile data and NFC or dropping calls. They are ad hoc and happen out of the blue for no apparent reason. My phone is a lot better but still does it. I've attached a screenshot I did earlier today when it did it in the car whilst I had streaming radio on and not signal problems. Its hard to spot as it comes and goes in the background and you only really notice it when streaming or playing games etc where you need a stable connection. It does seem to improve with updates but not completely solved yet. I'm waiting for my S23 to arrive but missed delivery driver twice but when it arrives I'm hoping it will be more stable than the S22
I don't think I could bring myself to get an iPhone, too many restrictions etc but I do understand your frustration. If I were you I would wait for the March update as a lot of stuff gets fixed in the updates, and see how it goes
Just to let you all know I've had one more go. Reset the Vodafone WiFi 5 (not 6) Router, Turned off all Connected devices for about Ten Minutes and then Reset Network Settings on the phone before turning ALL back on and Signing my Phone up to the Router. Touch Wood it hasn't disconnected since. I normally fine it's when I'm trying to use Headspace or Spotify Streaming I will update if any change. FINGERS CROSSED 🤞🏻 everyone!
