[AC Question]

I already have a phone that overheats and bootloops and can't get help because it's from Vietnam Samsung S7 (even though it is still under Warranty) don't want another headache! I chose this cus it met all the criteria I was looking for and had a removable battery! Now I saw post when I was trying to look up how to open back of phone saying it too had an overheat and bootloop issue but I purposely bought an American version with a U.S. Warranty so if I ever did have problems I could find somewhere in states to get repaired!! Please say it's not in current versions too??
