Fingerprint sensor & screen protectors

The fingerprint sensor is located on the back of the device. Using a screen protector has no effect.

 

OnePlus have been using under-display fingerprint scanners since the OnePlus 7.

But it might help to know which model you are planning on buying - that way if anyone has the same model they may be able to speak more reliably on how that particular phone works. Unfortunately while I do have an under-display scanner it's not a OnePlus (so I don't know how similar the tech is) and I don't use a screen protector. I can say that it worked fine with the one that Samsung had fitted in the factory (which I have since removed), but I don't know how comparable that would be to buying a film screen protector and sticking it on a recent OnePlus.

 

i use zagg screen protectors on all of my devices. they work really well with fingerprint readers that is on the screen. never had any issues. i love the fact that i can buy a protector and they will replace the screen protector for only $7......and they will install it for free!!!! i have a zagg booth in a mall near me that i can go to.

looks like zagg does not have one made for your phone. but they do have it where the salesperson can cut a custom shield for almost any phone. they had to do that for my z fold 3.

i hear great things about whitestone as well:
