Mi A1

[Discussion] Mi A1 cellular network and Wifi signal fluctuation.

This post is a long one but please read till the end as many people using Mi A1 are facing this issue.

The cellular network on Mi A1 fluctuates very frequently. I had used Redmi 4A prior to this phone and this was not the case while using 4A. Also I am pretty much sure that my area where I live has strong cellular nework coverage. Sometimes all the signal bars on Mi A1 vanishes which is strange and again it appears back within next second.
I wanted to find where the problem lies and I did some experimentation on Mi A1 and found the following.
Initially I used only single SIM (Vodafone), it was then when I realised the network issue (signal bars fluctuating).
Then I inserted two SIM cards (Vodafone in slot 1 and Reliance in slot 2) and set my data connection to Reliance SIM. Then I found that the signal bars of Reliance SIM are fluctuating. At that time I thought that Slot 2 was defective.

In order to confirm, I swapped the SIM cards and this time I activated data of SIM 1. Interestingly SIM placed in slot 2 (which I thought was defective) gave full signal bars now and SIM 1 signal bars started fluctuating. After that I turned on data of SIM 2 and its network started fluctuating while SIM 1 gave full signal bars.

Final Verdict - From my research I found that, the SIM whose data we activate suffers cellular signal fluctuation, no matter in which slot we place that SIM.
Also my WiFi signals do fluctuate as well,  WiFi too being related to internet.. maybe there is some bug that leads to fluctuating signal. (Signal fluctuation occurs even when I am close to WiFi router)

You guys can also try the same and confirm my findings. If confirmed we can inform the developers and they can work on it.
EDIT - Issue resolved for Vodafone and Jio networks (since I am using them) after October Security patch. But other users using Airtel, BSNL etc on 4G network are still facing issues.

I have the exact issue on my mi A1.
Hopefully there is an update coming to fix this.

Has anyone found any work-around for this?
