Yes, you probably should not have to Factory Reset after an Android version update, but I have always done it, & never, ever had any problems.
However, as has been reported & posted several times here on Samsung Members, there was a problem with the update itself.
Samsung has been MUCH better & faster in getting Android version updates released, this time something went wrong with the update, although it doesn't seem to have affected everyone.
Samsung pulled the One UI V4.0 updates for the S21, but it looks like they are resuming the updates, so likely everyone who already has the One UI V4.0 update, will likely receive a new update shortly.
But a Factory Reset won't ever hurt.
I just updaded my Galaxy S10+ and now there´s some kind of balloon floating on my screen (Letter T inside a green balloon), i cant remove it, tried holding the balloon and searched on the settings but nothing worked.
Am i the only one with this problem?
Go to 3 dots top right in message app, then settings, then notifications and check if Show as bubbles is turned on. If it is on you will get what you are experiencing.
Hi Jbb8s5, I suggest you please try performing the wipe cache partition by following the instruction below and write back to us.
Turn off the device.

When the Android logo displays, release both keys.
An 'Installing system update' message may show briefly before the Android Recovery menu options appear.

Press Bixby / Power key to select.
Press the Volume down key to highlight Yes, then press the Bixby / Power key to select.
