iPhone 17 touch inconsistency: Touches not registering and 'hold' interruptions

Hello guys, I bought a new iphone 17 last week and I noticed 2 strange behaviors in the touch screen using iOS 26.1

1- Sometimes the touches are not registered and i have to touch again. Inconsistent and rare but it happens.

2- However the main issue is when I touch and hold, it registers normally but sometimes the “hold” does not continue as if i removed my finger but I did NOT. It happens in random parts in the screen but mostly around the right and left edges. Ex: holding on the right side of the screen on a facebook video reel to speed it up. The video is speed up for less than a second and then slows down (acts as if i removed my finger as i said earlier). This happens with different apps and i tried touch screen tests and it happens also. It is also rare but more consistent than point 1.

Note: I also tried without a screen protector and same behavior happens.

So is this normal? Does it happens with any other iphones? Specially 17? Could it be an ios issue? Or it is hardware?
