Hello, hope someone can help. I have an issue with my S21 Ultra wherein my network has been intermittent or while using my data it goes airplane mode then goes back on. From 4G/5G symbol it turns into this 🚫 then goes back to 4G/5G after a few seconds. I have tried to factory reset my phone but the problem still persists. It is not a service provider issue also since I already replaced my sim card to a new one. This started to happen when I last updated my phone last January 15, 2022. Appreciate the help/recommendations. Thanks!
