I have recently bought this Samsung Galaxy M31 model. The issue: my Vodafone 4G network disappears several times in a day. The network strength decreases to 2G and then no network at all( Emergency calls). Even when it shows 4G network, the net speed is not that good although Network coverage is pretty good in my area. This is very frustrating. Please resolve this issue.
The same Vodafone 4G network works fast on my other phone. I've checked the connection settings and set network selection to "automatically select". Turning the airplane mode ON and then OFF doesn't help either.
If anyone had similar issue before and got it resolved please suggest a way
