One UI 5.1 disastrous update..

[Members_PDosMOa]

I regret updating to 5.1 on my Note 20 ultra 5G, completely ruined my device. Had some minor issues after the 5.0 update but I was not prepared for something like that! Data reception completely broken, refused to connect on 4G/5G, for Wifi need to be in the same room with the rooter otherwise the signal drops every now and then, same with wireless reception where I used to have 3-5 bars now it's 1-2, if I'm lucky.

Battery goes faster, charging is slower. The device is over 2 years old,  I understand how things work however this is unacceptable. I was hoping to keep the device until the end of the year, now I'm forced to get a new one. My phone is an important tool for my work , I need to have 100% trust , but now I have lost most of it.

I've had no problems with s21 since updating it.
Connects to WiFi. Battery better than it was .. get upto 3 days out of one charge.
No issues with any of the apps that are installed, but there have been quite a lot of updates.

5.1 update seems to be a big issue with some members

Have you tried wiping the cache partition on the phone. As I understand it was a big update on my A53. If that doesn't work. Then try optimising your device

I've just purchased S23 ultra as my main daily driver device.. As soon as I transfer my crypto wallets, bank apps etc to the new one, just out of curiosity I will do a factory reset on the device to see if it will improve anything. I was planning to get the S23 ultra within the year anyway (I was waiting for a possible price drop and preferred to buy after it would get a few firmware updates..),but it just happened a few months ahead. .. oh well.

Agreed, I have a note 20 as well and the 5.1 update erased my APN settings and I’m having multiple issues with connectivity with Wi-Fi as well. The settings say that the phone is connected to wifi / data but no apps are refreshing. I hope this is resolved quickly!

Hello, 

I am having the same issues. My camera can not save pictures I took. Will not recognize my sd card, and yes I checked my sd card to different device and it worked. Calls broken. It was working fine before the update.

I'm having serious battery drain on my note 20 ultra. When I first updated the phone was refusing to charge so I turned it off to charge. It did eventually, then the battery was draining in like 3 hrs! It's gotten a little better but its still drains ridiculously fast! Samsung needs to sort this! I'm having to have it constantly plugged in
