So frustrating! Is it me or have samsung started to really get rubbish? my watch 4 was bricked after an update in January, luckily i had proof of purchase and samsung gave me another watch as a replacement and now its my S21 ultra, which i purchased with cash and have no idea where the receipt is! I use my phone for work and it starts this restart loop sometimes, 6,7,8 plus times in one go, especially when opening a new app, if its on and idle, its fine. I have done all the troubleshooting, also a new battery and a technician even opened it to see if he could see anything obvious but everything was how it was supposed to be. Finally did a factory reset and still the same issues! Can someone guide me on what steps i can take with this? Im not sure if samsung will look at it as its out of warranty and potentially have no receipt. One thing I know this will be my last time with anything samsung, totally unacceptable for two of their premium phone and watch to just mess up like this after updates.. Unless they do this on purpose?
