Mobile network issue

I am not getting consistent mobile network, it often switches from 4g to 3g to 2g and vice versa. I am on Airtel India. This issue never occurred on the Galaxy S7. Please let me know if there is a fix or known issue.

Another issue, when 4g does not work it does not automatically switch to 3g/4g.

If I change to global auto, it switches but how do I set this permanently? Is it the right way to fix this issue?
