So I was in on the pre-order for the S21 Ultra. When I received my device I did the setup and began to use it as normal. Within a few days Sammy drops 2 firmware patches. After the second patch I begin to have issues with my mobile data just cutting out. I would have 3 or 4 bars and then nothing, zero connection. I called Samsung tech and Verizon. They could not fix the issue and blamed each other. Samsung had me install a regular 4G sim card as a test. Well huge mistake. That caused something in the phone to malfunction. I could no longer use wifi calling and got location errors. After hours on the phone with both companies, Verizon did the right thing and sent me a replacement device while Samsung refused to help me because I had it for 19 days. The new device is now working but I am still having the data issue. It really seems to be linked to the 5G setting. Verizon has removed the ability to select if you want global or LTE in the settings. I don't have 5G in my area and notice that after loosing connection it will briefly say 5G at the top. Hopefully they are aware of this and are working on an update. Now as for the screen, I have had ghost touch issues very similar to what is occurring with the s20FE. I will say, select a text thread to delete and it will select ALL of the threads displayed on the screen. I do not have a screen protector on. Samsung really seems to be having QC and development issues lately. I never had either issue on my s7, s8, s8+, s9+ or Note 20.
