Galaxy S10 in-display fingerprint will have this problem.
Over these last months, many phone manufacturers have been swaying away from the hardware fingerprint reader which was the trend of yesteryear. Nowadays, it’s believe that in-display fingerprint readers it’s the way to the future. Samsung seems to think so too.
Samsung flagship devices are confirmed to be announce on February 20th 2019 with their fingerprint readers built underneath the display which would be the first time Samsung is using this technology in their flagship smartphones.
While this is generally a good thing, recent tweet from a screen guard company called Armadillotek will make you think otherwise.
Armadillotek clearly stated that their screen protector will render the Galaxy S10 in-display fingerprint reader non-functional so users will be force to either choose to use their top dollar phone without protection or use another means to secure their smartphone(other than the fingerprint reader)
It’s important to note however that the upcoming Samsung Galaxy S10s may have no fault on their own but that Armadillotek’s protective solution might be the one facing this problem.
Whatever happens, the cheaper S10 lite will certainly not face this issue as it doesn’t feature an in-display fingerprint reader. You can read more about the Galaxy S10 lite from here and recent live image of the Galaxy S10 plus from here
