LTE and 4G issue with m30s after Android 11 update

[Neo7]

Hello samsung mem.

 I am facing network issues in my Samsung m30s.

The volte is not coming on top right corner even when vlt is on and some times the 4G data turned off autoimmunity even when data is on 

After the update am facing these type of issues 

i can't make a call there is network problem and call drops automatically. Facing this issues from A month. I don't know how to fix this problem.

Even when the data is on there is no symbol of 4g on top.

After updating to a major software upgrade you should perform factory data reset it may solve some problems

U r using jio or airtel. See I would suggest remove the sim from sim 1 and put it in sim 2 and try. Maybe it gets solved. 🤔 like in my case I am using jio services honour m51 which is good I am happy

RYT NOW I AM USING VI SIM . YEA I TRIED THAT SIM 1 TO SIM 2 BUT IT WAS SAME AS IT WAS BEFORE

Boss vi is a gone Co. Better change your network soon. I have been keeping a huge track on Vi since 6 months now. Have recommended alot of people to leave VI and go to airtel or jio.

Sometimes jio doesn't work in the area . I tried jio too

It might be a problem of Vi in your area as well. Will suggest you to turning on flight mode and reset network settings.
