I am sorry to hear that @robby14 .
This may be already on our colleagues guide but would you be able to try the following things?
-Clear the Samsung Members app cache and data from the Settings> Apps> Storage> Clear cache and then Clear data.
-Check if there are any pending updates available from the Galaxy Store> Menu> Updates> Update all.
In regard to the ghost screen is this visible in all the Tab screens and apps? Have you run the following test?
Dial *#0*# into your Phone app keypad > Tap on ‘Red’, ‘Green’ and ‘Blue’ > Observe the colour displayed. If the colours still show the lines, there may be a hardware issue with your device. If this is the case the best thing to do is having this looked by one of our engineer in situ. You can arrange this from here if you are in the UK: Book Your Repair with an Authorised Service Centre | Samsung UK
If your are in a different country please select the right one from this list and head to the Support page available there: SAMSUNG | Samsung UK
