Hey how are ya?
Yea it happend to me and to my gf too.
We bought 2 tab s7+ 2 days ago and its happening on both of them we dk if its ok.. 🤔
If you find out if its fine i will be happy to know 😁
Hi it's me again oh, I found how to fix the issue of the flashing Once you turn on your Samsung Tab S7 Plus. You have to hold down the power key and the volume down button at the same time the screen will go black until you see your Samsung Logo Pop Up let go of the button.
What this does is it gives it a hard reboot it does not reset nothing it doesn't erase none of your files it just cleans your RAM and cache. Trust me I've done this already and my tablet haven't had no issues with the screen flashing for the past three and a half weeks. Thank you & good luck
