Open GoodLock and then Gallery Assistant and click on Add Watermark. You can then select the layout White or Black.But make sure that you remove watermark from Main Camera settings if its On.In case the watermark is already On then the Gallery Assist...
This is what has happened to my S22 Ultra after the update and Samsung refuses to accept their mistake and now wants me to pay 22k for display replacement as it's out of warranty.Ridiculous service!!!!
