My Samsung Galaxy s8 plus has been doing strange things for a while now but just recently it decided to lock me out of signing into my phone on my Google account so I can't update apps or view my photos or download things from my drive. It also locked me out of my Yahoo email and basically any important account apps. It corrupted a bunch of my data and I don't know what to do. I can't even log out of my accounts so that when I factory data reset my phone I won't lose all of my data and content due to the fact it hasn't been backing up since it can't log into my Google account. Please HELP!!
Can you log into your accounts using another Samsung phone just as a process of elimination.
A Samsung Experience Store or Samsung Service Centre can run a diagnostic test on the phone itself @Clauren
