According to the reports, it seems that several users had complained about how the update resulted in their phones crashing, where apps would freeze for no reason and the phone had to be rebooted. It was also reported that some users encountered some issues with the fingerprint sensor where it was slow to respond.
It is unclear how widespread the problem is, but it seems to have been severe enough where Samsung has decided that the best thing to do for now is pull the update. There is also no solution to fix the problems at the moment, where apparently doing a factory reset doesn’t seem to do anything.
Some users are claiming that their phones are fine, but we suppose it’s better to be safe than sorry. The company is working on a fix but it is unclear as to when the update will be ready, so if you haven’t updated your phone yet, you’ll have to wait for the fix to be released.
