Frequent network signal loss after updating One UI

[eyasalmamoun]

After updating my Samsung S22 Ultra a week ago my phone started loosing coverage even within open areas and in areas where it used to have good signal before the update. A newer release was uploaded today and still the issue persist. Any idea how to fix?

Other phones in the same room are capturing good signal while my S22 isn't. Galaxy S22

It is even worse with the latest version. I can't even browse the internet without Wifi

Hi @eyasalmamoun and may I extend a Warm Welcome to the Samsung Community Forum 👋 

Some troubleshooting steps to try and resolve the network connection >

Settings > General Management > Reset > Reset Network Connections > Reboot the phone by turning it Off and On. 

Can you try the sim card in the secondary slot. 

Also as a process to rule out a sim card issue are you able to try your sim card in another phone  ?

And if possible another sim card in your phone to rule out a phone issue. 

There is a diagnostic tool found in your Samsung Members App. 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If you perform a forum search you may find existing threads with some further help or guidence within.

Samsung phones are just garbage on 4g/5g. Even WiFi 6 is garbage. i have 1.1gb speeds on my WiFi, but I only get 600 my gf iPhone smashes 1gb speeds yet these clowns think it's acceptable a £1000 pound phone and I have keep hitting airplane mode on and off just so it can connect to local cell tower

Hi,

Did all of the above on my own and with Samsung Support only to be told that now that my insurance is up, I would have to pay out of pocket for it to be diagnosed and "fixed" by one of their 3rd party service providers or mail in my phone (that I mentioned I need for work and daily life) and it may take a week or more to return to me with no loaner phone to use. I paid almost $1500 USD for my S22 Ultra and now after this software issue it is an off and on again paperweight.

I have both an iphone and a Samsung s22 Ultra and I was jus complaining about the same things. I was in favor of Samsung but after this experience with no accountability from Samsung, it may be time to convert fully.

Here we are on Jan 22nd and I'm still having this problem. I should not have to buy a new phone because Samsung's update ruined connecting to my cellular network. My phone is fine, it's just the connectivity. And with so many others having the same problem, this should have been fixed months ago. I have had a Samsung phone every year for over a decade. I truly do not want to switch to Iphone but may have no choice. I'm paying for service I can't even use.

It's a shame that we are having this problem. It's ridiculous to pay for an expensive phone that does not work.

The only reason I converted to samsung was because huawei don't google anymore.

Now I am completely regretting not getting an iphone instead
