One ui 7 messed up my phone

[ShreyanshDk]

After the one ui 7 update my phone is messed up

Unusable even

Constant restarts

Camera won't work and crashes

Laggy 

Home ui not working

Etc

I don't know what's the issue

I have the snapdragon variant sm s901e

Service center guys know only one thing to say "motherboard replacement"

Screw you samsung

How can a flagship be like this

Is it even flagship at this point

Such expensive phones not even lasting 4 years properly

Samsung broke my trust

Thinking of switching to iphone after this one
