Recently, I updated my phone to One UI 6. After 5 days, the problem started with freezing and automatic restarts. Initially, it occurred once an hour, then on the second day, it happened more than 5 times in an hour. Additionally, the screen displayed lines in various shapes when the phone froze, even without using any apps. I went through every troubleshooting process recommended by the support team, such as the screen test using the *#0*# code (which showed no screen issues) and performing a wipe cache partition and factory reset.
After the reset, the phone started restarting automatically again after a few minutes, although the lines didn't appear this time. So, the next day, I booked a repair with Samsung online since there were no Samsung centers in Ireland. Upon checking Samsung's repair sites, it directed me to the Fonefix store in Ireland, where they informed me that they could service it for free since it's under warranty.
The technician suggested changing the main board of the phone after seeing attached pictures, but since they didn't have the parts available, I didn't proceed immediately. However, after receiving another update on the same day from One UI, the phone hasn't shown any problems for the last 24 hours.
Should I wait for the problems to reappear, or should I change my board straight away since I only have 8 more months left in the warranty?
