Yesterday my wife and I were both prompted to update our Galaxy S10e's. We both initiated the update and then we both had the identical issue. Our phones rebooted tens of times until we were presented with the boot screen to try safe mode, delete cache, etc. After trying all of the options without success we were forced to factory reset our phones which has been a huge hassle.
Has anybody else had a similar problem? If it was just one phone then I would write it off to the tech gremlins, however, that this issue happened to both of our phones sure seems to point to a big bug in the upgrade.
