The Galaxy S10's in-display fingerprint scanner won't work with screen protectors

Samsung Galaxy S10+ renders based on leaked information

After five years of using traditional fingerprint scanners, Samsung is preparing to make the switch over to ultrasonic in-display alternatives with its Galaxy S10 series. But according to one case manufacturer, this move may bring one notable drawback.

In order to ensure early availability, Armadillotek has been hard at work preparing its Galaxy S10 and Galaxy S10+ cases. But through its own testing, which has involved “real” Galaxy S10 phones, the case maker has determined that the new in-display fingerprint scanner doesn’t work well with screen protectors.

Because of this development, the company’s trademark Vanguard case won’t include a built-in screen protector as has been the case in the past.

For most people, the lack of screen protector compatibility is unlikely to be a deal-breaker, but for some who prefer to protect their phones entirely, the news may come as a bit of a disappointment.

Despite the bad news, consumers interested in the cheaper Galaxy S10E can rest assured that screen protectors won’t affect day-to-day use. After all, unlike its premium siblings, this model features a side-mounted fingerprint sensor.

That's not good. Was so looking forward to the S10, but this is a deal breaker. I guess long live the S9. I'll stick with that for the foreseeable future if this truly turns out to be the case.

Welp my plans of pre-ordering just went out the window. I’m Not buying any device that can’t be protected unless I want to lose functionality

Whether you like it or not. As for the techonology stands right now, Screen Protector or tempered glass protector is still a must. Samsung’s curve glass phones most likely to break when accidentally drop. Samsung new sensor not working with the screen protector, if its true..will be a deal breaker for some or most People. And Samsung Phones doesn’t age well. Galaxy S8 is about 2 year old but many of them already has Screen issues like Dark spots, Screen burned, Green Vertical lines, broken glass, Heavily scratched finger print sensor. But at the end of the day it is still your money, so you still decide. Don’t let the stupids here in the comment section affect your decision.

Who wears Screen Protectors? That's like wearing a condom and we all know there is no fun in that

Maybe the screen protectors will have a cutout in them?

Hate screen protectors. How people believe some 2 dollar piece of plastic will protect a 800 dollar phone is beyond me. Is there a name for such a crowd? Can we get one? ScreenProtectorSheep? Have a feeling the S10 is going to feel amazing in hand. Will be a hard toss up between the Note 9 and S10.

You hate them, fine But some of us like them. Every phone i have had since the s3 has had a case and screen protector from day one on and when i go to resale them they still look new and i got top dollars for every one of them. I also buy the best i can, not a $2 one.

I wont be happy with this at all if true. I put screen protectors on the day i buy a phone and it doesn't go with out tell the day i sale it, same with a case. I wish this craziness would have never got started. Just keep them on the back.

Been strictly using phones with in display fp scanners for almost a year now and every single one of them has had a protector since day one. The tech should work with a screen protector on it

It's different tech than the optical sensor you've been using.

If the S10 line under display Fingerprint Scanner will Not work with a Screen Protector, then what about the News of the S10 Line Shipping with a Pre-Installed Screen Protector?

All S10 models will have factory pre-applied screen protectors. PA forgot to mention that.

Haven't used or needed a screen protector for years. I can see this being a problem for children and people with Parkinsons but overall shouldn't be a big deal.

I am not a child or do I have Parkinson's yet I won't use a phone unless it has a screen protector on it. Scratches buildup on the screen with usage. I keep my phone in my pocket and without a screen protector, even deep scratches can occur.

I do too. But I don't have these issues. End of the day, if a screen protector is important to you, buy something else. It was difficult to get any decent screen protector for Samsung flagships anyway. It's not a big deal at all or they wouldn't be selling.

Well, it seems that the side-mounted fingerprint S10 E will be a best-seller. Looks to have excellent specs and be around 8mm shorter than the S9.

If an iphone has fingerprint scanner and won’t work with screen protector, then the outrage would be 1000%, just like removable battery, 3.5mm jack, and so much more. But when an android does something like this, then its just common to accept things just like this. Simply who cares!!! Anyway, this would fail as to many people would go for Note 10 then when note 10 comes then they would be excited to S11. In reality, they don’t have money to buy, just want to feel that they can.

Ah the Android troll is here. And it depends if there is a good technical reason why a protector won't work, neither Samsung nor Apple would get commented on (by me at least). Also, brands (like OnePlus & Google) who got rid of the 3.5 mm jack got plenty of comments on that one. But there will always be a few who justify everything their favourite brand does (looking at you trollboy)
