This is a very expensive phone and I paid full price for it. Although Samsung has tried to improve the glass the fact remains that it is still vulnerable in third party testing. I want to protect my investment with the best case and tempered glass that I can. Unfortunately I also want to protect my accounts and the fingerprint reader does not want to work with any tempered glass screen protector I have tried so far. I did find one that seemed to work for the first few days after I applied it but then even it stopped working and i cannot afford to replace it every 2 days. Please Samsung give me some helpful advice!??
From My understanding, Whitestone make a "Dome Glass" that many users on this forum say works well with the in screen fingerprint scanner, and is a glass screen protector. I have watched a video on youtube that shows the install process, it is arduous, and the protector is expensive, but if you have a friend that has a Note20 device like yours, you can split the cost as it is a pack of two...
The above link is for the Note20 Ultra, but they do have one for the standard note on that same site if that is what you have.
As others have written: stick to film protectors. The only TG that claims to work is Whitestone, but it's very expensive, hard to install, very fragile, and WILL reduce the accuracy of the FPS.
