Since upgrading to Android 11, I can no longer connect to anything unless I am on Wifi. My signal strength still shows as good with 4G but connectivity fails. I then downgraded one of them back to Android 10 and it started working again. Can anyone shed any light on this issue. I issue many Samsung devices to colleagues and fear they may all start beginning to get the same issues I have.</P> Tue, 20 Jul 2021 16:20:14 GMT https://stg-eu.community.samsung.com/t5/tablets/android-11-stopping-mobile-connectivity/m-p/3699121#M9681 RW78 2021-07-20T16:20:14Z https://stg-eu.community.samsung.com/t5/tablets/android-11-stopping-mobile-connectivity/m-p/3701358#M9691 Who is your carrier?
