Hello,
We are servicing two live games in the app store.
While developing our game, strange multi-touch malfunction is detected.
When you touch both fingers on screen simultaneously, input that touches the screen first(ex: left thumb) is OK, but following one(ex: right thumb) is not detected on the edge of the screen sometimes.
Summary :
1. When you input both fingers on the screen, later touch ignored on the screen edge intermittently.
2. To recreate the problem, I built multi-touch test app that only displays the touch input.
3. While the first touch continues, the second touch on the edge ignored often.
4. It occurs in iphone6 and above. It seems 5s and SE did not show this symptom.
5. No-input zone on the edge in iPhone 6 and 6+ around 0.3inches thick both side and bottom.
6. No-input zone in 7,8 is thinner than 6, around 0.2inches, and in X, it is 0.1 inches.
Did anyone experience this before?
