Network issues in Galaxy M30s

[AmitKumarSamnani]

After the July Security patch update, the network issues solved. But from past 10-15 days, I again see this issue. 

Network usually changes from 2 to full point network and vice-versa (causing battery drain) and sometimes it changes to E (2G)

Please Samsung fix this issue 🥺🥺🙏🙏

Like now when I was writing then too network changed to E (2G) and then back to 4G.

Temporary solution which I gave you before too was to lock band 40 it is giving comparably good speed.. But sometimes / frequently getting no service and emergency calls error which didn't happened before july security.

@Neo7 I tried sending error reports but no use 🤷‍♂️

Many friends using m30s facing the same issue.Most of the time sim1 network fluctuating between 4g & E and it is not happening after a specific time period.One dont know when will it fluctuate from 4g to E.
We have written many feedback regarding this but unfortunately they are not fixing it.

turn off volte calls for sim 2

[AmitKumarSamnani]

If I had to turn off VoLTE for Sim 2 then what is the use of Dual VoLTE Standby?
Secondly, SIM 2 is Jio, if I will turn off VoLTE, then I won't be be able to send or receive calls from SIM 2
