I recently competed whatever software update Samsung required for my phone (security?), and now, my phone is overheating, constantly losing signal, the screen is discolored and the image on my home screen is stretched out of proportion. I cleared the cache, and this has not helped. I adjusted the display settings, and this has not helped. Please don't make mundane suggestions; I checked, this is happening frequently. The phone was fine, I ran your update and now it is practically unusable. I can't make calls on it, because it randomly loses signal...all of the time. I got this phone brand new less than four months ago. What is the solution?
Do you experience these symptoms if you test your device in safe mode? If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identity and remove the app that may be causing the problem. Give this link a try: https://www.samsung.com/us/support/answer/ANS00062983/
Just to clarify did you wipe the cache partition on your device?
Any luck with help, or did they just turnbyour phone into a brick? I got this thing new, and will be very upset when they exchange it for "refurbished," especially during a pandemic.
