Since I updated my Samsung Galaxy Note 10+ to One UI 3.1 Android 11, I have no Volte so I cannot use apps, browse web, etc during calls. I've checked Safe Mode, Turned off and back on Airplane Mode, removed/reset sims, nothing. Can anyone assist?
to the OP.
This may or may not be a carrier issue, so please check with your carrier to see if they can help with this matter.
If it's not their issue, then submit an error report to Samsung Members app after attempting to call/browse/text again.
