I have a noteworthy ultra and it has what seems like a factory set screen protector.
It has since started showing bubbles beneath the display, doesn't look like it can be easily removed/ it's part of the device
Just looking for advice if cool
It's just a plastic tpu factory fitted screen protector so will just pull away.
But as removing it will leave your phone screen open to scratches etc I would suggest a replacement screen protector or a case with one pre fitted.
I prefer the Whitestone Dome Glass Screen Protector on my Samsung Note 20 Ultra 5G as it's the best available that adheres to the while screen using special silicone adhesive and works very well with the fingerprints sensor.
There are other options available but I wouldn't recommend the versions with the glue just around the edges of the screen protector as they tend to just pop off !
There are plastic tpu options available too.
