Device specs

Haven't noticed any problem so far on my Air 5.

For AstroDX side, can you point out what chart you faced this issue on? Or maybe I'll write a test chart which is full of 12345678,12345678 for testing.

For factors outside of AstroDX's control, check to see if 4-5 finger back-to-home gesture is disabled, and also assistive gestures while you're at it. Check the screen protector (mine's plain glossy glass)

Ah so it is a WiFi slide situation. Interesting.

For matrix touchscreens used on phones, I notice that it is easy when two fingers are really close to each other, that they are recognized as 1 finger instead. This doesn't happen since maimai arcade uses touch sensors and is more of all-or-nothing for each zone.

I hypothesize this is the issue. If you want to test for this, intentionally cram your fingers in a WiFi slide such that they may appear like 2 fingers to the iPad, and thus not hit all 3 sensor zones.

I don't see much way of compensating for this. For some Android devices, they have a hidden and seldom used "force touch" feature which actually for each touch, there's a hidden attribute of the force (measures surface area?) which can be utilized. But doesn't work on all Android devices, and vanishing unlikely that modern Apple devices has this feature after Force Touch feature got dropped.

I cannot reproduce this issue on my device. iOS 15.3 (19D50) AstroDX 2.0.0 (Build 105) iPad Pro 12.9inch, gen 5th

If you play on iPhone, this behavior is expected, since latest iPhone still only support 5 point multitouch. Can you confirm this issue happening on your iPad as well?

Just noticed you reported this issue happens at build 103, which known to have some compatibility issue with iOS 17 (we didn't upgrade SDK at that time).

Please update your game in TestFlight and try again.

Here are videos...sorry for the bad quality. I can sure my iPad is OK because I just go to apple store to seek help last week, and they tell me this iPad is pretty good. And it's different from #52 because after this I can use the area well. And if I restart instead of quit, I can reproduce the problem again.
