Does your network also switch between lte & 5g most time
No more here's a little trick 😅 you may already know it or may not ....
Lets start....
Go to call ( phone app ) and put *#4636#*#*
( *1 If no menu pop up then install another phone app eg Google phone app and just write same code there ( don't dial the code )
*2 please turn off auto blocker from settings before run the code )
Now a menu pop up
At there bellow a option will be there preferred network type
Set nr only option there
You will get 5g all time now
(* note for some areas at 5g no incoming calls might be come , so remember to swich back to auto or lte only )
Hope it helps
You may ask your queries in comments 😀
Just by pressing this we r directly inside and we can change it to nr only. No *#*#4636#*#* needed.
