S21 Ultra Worst Internet

[Rishikesh1]

I have been using S21 Ultra For around 50 days now. The phone is good, heating issue has been reduced and I am liking it. The major issue which I have seen is of Mobile data. The mobile data suddenly stops completely. Here is the poc for reference 

The mobile data get stuck like this and this happens frequently. I have to toggle flight mode and again to get internet back.

The mobile data works well but this issue is too frequecnt and completely ruins the user experience. If you need a stable Internet connection then this is a big trouble.

I have used same Sim and network in Galaxy Note 9 but haven't face thiis issue. I have done, Network settings reset, changed sim and even did hard reset but this issue is always there. I have talked to customer care multiple times but they arent able to sovle this. This issue also remains in SAFE MODE. There is something which Samsung needs to fix. I have seen others users complaining for the same. This issue might be of Jio also but I haven't witnessed this in Other phones. 

I don't know if I will get solution for this or not but if you are buying S21 Ultra do note you might also get this issue. Also I am open to any suggestions which you might have for this issue apart from the things whi I have already mentioned. 

Note: Updating this on 23 Nov 2021. If you need stable Internet you can turn off the other sim in simcard manager then it would be usable. Worked for me. No other solution till now available.

If anyone have perfect solution, please share.
I had escalated perviously and shared their feedback to sort out the same in last week but it was failing again

Samsung needs to step in to resolve this, and treat this as very important for repeated issues.

I would recommend all of our S21 Ultra or s21 user please register it and escalate it all together at once, then the issues can be seen, I guess....

Thanks for writing in. I have already did that multiple times. They gave me solutions also but none of that worked. Recently I have shared my log files but haven't received any solution. If you can escalate it through mail. It would be appreciated.
