Hi,
I just want to say a big thanks to Samsung for the latest update which has ruined my phone by not getting 4g and 5g signal anymore on sim 1 slot .
God job Samsung for making us to switch to other brands.

@Cvi19: I'm sorry to hear that you have encountered this issue following a recent update. Please can you try restarting your Galaxy S21, then head to Settings > Connections > Mobile networks > Network mode (SIM1), and make sure that this is set to 5G/4G/3G/2G (auto connect).

I have the same problem with my S21. Since the update, can not get 4g. Tried restarting, reinserting sim card, toggling flight mode on off, checked all the settings. Nothing working. Extremely frustrating. Please help!

My issue is worse, since the update I'm not getting any signal at all. My phones only a year old
