Hi, my phone keeps getting weird pixilated things on the screen then freezing and then it turns itself off, i have tried completely resetting the phone and its data but nothing has worked, I'm wondering if anyone can help, thanks!

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

I tried pressing keys simultaneously and nothing happens

[Glenntech]

Did you connect the phone via a USB C cable to a PC or another device?
Have to follow the procedure as laid out to get it to work

[Hannah97]

I have tried it yes

Literally nothing comes up if I press both keys, I tried to plug my phone into my partners phone (double ended charger) and nothing

@Idekkk: If you have attempted the troubleshooting steps provided by @Glenntech, and the issue has persisted, then please try restarting your Galaxy Z Flip3 in Safe Mode. This will disable all third party applications, and help to determine if the problem is stemming from an external source. 

To enter Safe Mode, press and hold the Power button until the 'Power off' prompt appears on the screen then release > Touch and hold Power off until the 'Safe mode' prompt appears then release > To confirm, tap Safe mode.

With Safe Mode enabled, please monitor the phone for a few hours, depending on the frequency of the freezing/restarts. If you notice an improvement, restart the device as you would normally, and uninstall any apps that you have added since you first encountered the issue.
