Band is shifting
- Thread starter umesh2509

LTE (real 4G) was originally a data-only protocol. Although some networks now support voice over LTE, not all do (I don't know whether only some handsets support it in addition). So switching from 4G to 3G or 2G when making a call is not unusual.
Switching from 3G to 2G when making a call makes less sense if it shows 3G when receiving calls when in 4G mode.

I don't actually have a V20 but that pattern and sequence of events you're describing doesn't seem to be a very common type of situation. Is this happening all the time or just occasionally? Does it happen only while you're traveling (as in actually being in motion) or even when you're just standing in place?
Maybe try re-seating your SIM card, although that would be more applicable to a random issue, not so much the sequential one you're experiencing. Have you tried contacting your cellular carrier?

Shifting from 4G to 3G happens all the time. 3G to 2G is not often, I think that was only once due to weak signal.

It switches from 4G to 3G all the time. 3G to 2G is negligible. Do you think switching from 4G to 3G is also uncommon ?

I was asking those questions to try and get a better idea on what the problem might be. If you're just standing or sitting still and this happens all the time I'd be inclined to look into something phone-related. If you're driving and far enough where you're physically moving between the coverage ranges of different cell towers that sounds more like a typical issue any of us might experience. But again, without more context from you, that's all just speculation without any substance.

No, I was just sitting in a place. And it happens all the time. I didn't travel anywhere.

Try removing your SIM card and putting it back in its slot. Send a message to your carrier to see if others are having the same problem.
Is this happening when you're doing a specific task? Watching streaming content of some sort (like Youtube for instance)?. Or during a phone call there are frequent interruptions as it steps down in speeds. (which could be another issue as voice phone calls work through pretty low-bandwidth bandwidth being highly-compressed, mono so even a 2G connection should suffice).
