I have put Jio 4G sim in slot 1 and Airtel 4G sim in slot 2. Things are working fine and I am getting LTE and VOLTE signals as shown in the screenshots ! But randomly my LTE signal is getting lost ! All I need to do is to go to sim settings and disable sim 1 and again enabling it will bring signals back. This is happening randomly during a day and happening 4-5 times in a day. I have even tried to put second Jio 4G sim to check but same is happening with second sim also. Tried even putting both Jio 4G sim in sim slot 2 but same problem is happening. But my another sim of Airtel 4G is not having any such issue.
