Touch screen problems

[MrsMgC]

Recently I've been having problems with my touch screen and lag with certain apps. I've followed Samsung advice on there website, restarting, performance check and virus scan and nothing has helped. Has anyone else had the same issues with S22 Ultra, only had this phone since the summer so pretty disappointed that it's started having issues like this. Especially when I need my phone for work being community HCA (Health Care Assistant). Any help from the Samsung community will be fab before calling them over the weekend

Make sure you have the most up to date software and clear cache partition. See if that helps

I have s22 Ultra and have not found any issues of lagging and touch issue

Might be worth clearing the Partition Cache on the phone

It's a quick simple process that can help a lot

Wiping cache partition fixes some of the bugs and improve performance by removing unwanted cache files.

Turn off your phone.

Connect your phone with a USB cable
to PC or another Samsung mobile

You will see the charging icon on your screen.
Wait till it shows charging with battery percentage.

Next, press and hold the Volume up and Side key simultaneously.
You can press the volume up button just before the Side key.
The Samsung Logo followed by
Samsung Galaxy appears on the
screen.

At this point, release the keys
Phone will boot into Android Recovery mode

In Android recovery mode, using Volume keys, choose "Wipe Cache
Partition" .

Then press Side Key to Confirm by selecting "Yes" and then press Side Key

You get "cache wipe complete" at the
bottom of the screen
Restart the phone to complete the
process

It could be an issue with a theme or app as well. But try this first and see how you go

Try going into Settings, Apps Choose the app[s] your experiencing issues with , Storage, Clear Cache and if absolutely necessary Clear Data.

Can you elaborate to which Apps you think maybe causing this @MrsMgC 

You can also try Safe Mode > Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

If all else fails then as a last resort back up and Factory Reset.

If I can be of any further help then please don't hesitate. Take care.  😎

Let me I share my experience about this issue on Galaxy phones. 

After 4 - 5 Months I resolved it by myself. It is very interesting thing and strange behavior of my phone. When for a while I used low Amper charger for my cellphone suddenly it obviously Ghost touch illustrated on my phone. I referred and look for too much website and too many sources about this issue but unfortunately I found nothing to resolve it. A day I thought and guess maybe it is because of lacking electricity or Amper it happens. I changed charger to higher Amper 3 then I noticed exactly Ghost touch disappeared... 

That is all now the my Galaxy works like as new days I bought it. 

Thank you Samsung 

I recommend to all user please use original charger Samsung phones according to the which model you have buy or utilise it. 

Thank you
