iPad Pro 12.9 touchscreen is unresponsive from time to time
iPad Pro 12.9 touchscreen is unresponsive from time to time
I bought the iPad Pro 3 months after released date until now. Recently my iPad Pro sometimes unresponsive to any kind of tap but as far as I know 5 finger gesture still works but 1/2 fingers tap and swipe is not possible.
I think it’s a software issue. Updated to ios12 public beta 3 days ago, no unresponsive screen sense that time, prior it was happening daily. Home button, power and volume rocker all worked, but couldn’t do touch screen. I’m running a 2nd gen iPad or 12.9 and all is good now.
Okey, seems on my end it was a hardware issue (I tried hardware reset, disabling iPad features, removing apps - nothing helped. It looked like it helped but then touch delays were getting back). Apple replaced the iPad and all my problems went away.
"I removed all of the widgets on the notification page , turning everything off (background refresh, Siri, dictation, thumbprint lock, location, gestures, Bluetooth, etc. removed my cover with “Smart Cover feature” and it seems to be helping .
i suspect that it’s due to the accelerometer which causes the delay
Different things seem to be working for different people.
What hasn’t worked for me: Full erase, iTunes restore
Widget Removal
Slide from top downswipe left to right one timetap “edit”tap “-“ then “remove” for each of the widgets (e.g. news, weather, calendar)tap “done” at the top/ middle/ off to the right hand corner after removing.I do believe that this is a software issue because I wasn’t experiencing this with 10.2. Hope this helps.
The problem still occurred after the above steps were taken
Update (01/03/2019)
On iPad 12.9 2nd gen, been having touchscreen lag since iOS 11. I updated to 12 and the lag seemed to stop for a while but eventually resurfaced. I did the small updates here and there. I noticed that the touch problem seemed to get better immediately after the update but eventually returned after some time had passed. I just updated to 12.1.1 and everything seems to be ok for now. Will continue to monitor for touch screen problems. If they don’t come back, I’m never updating again!"
"I have been suffering with this issue for months now. I’ve had my suspicions that it is a software issue but the problem started occurring for me at a random point after having iOS 12 installed for months. The responsiveness of the touchscreen has gradually dropped over time, while the Pencil continued to work perfectly. Eventually I started getting skipped keys while typing, scrolling would pause mid-scroll, but the Home button and rotate always worked perfectly. It was driving me crazy, I was paranoid that my fingers were too dry, the surface coating was deteriorating, my fingerprints were causing detection issues on the huge display, and thought perhaps my screen protector was causing the issue. I noticed that the condition improved somewhat when I removed the iPad from its leather case. This indicated to me that the problem lies in the capacitive touch part of the display.
TL:DR, I was able to fix my iPad 12.9” Pro by measuring the flatness of the screen and gently flexing it back into shape. Even a tiny amount of flex can cause the touchscreen to stop working correctly.
To do this fix yourself, you need a precise flat edge tool. I recommend getting a machinist or carpenter square that has a sharp edge, like this one: https://www.amazon.com/Tools-Combination...
Once you have a nice flat edge, hold it against your screen at vertical, horizontal, and diagonal left/right. If your issue is caused by screen flex, you will see the screen fail to touch the edge of your measuring tool. You need to flex the iPad until the screen is in full contact with the straightedge from every angle, more or less. Just be very very careful not to over-flex the iPad, it’s full of sensitive electronics and dangerous lithium ion batteries :) I didn’t flex it more than maybe 1/2” deviation total, and that was enough to make my iPad flat again. My iPad was maybe only 1-1.5mm deviated from flat, and it was enough to cause tons of issues. I’d say that’s an issue with the design.
I finally got frustrated enough and did this fix today, my iPad suddenly became as responsive as it was on day 1, no reboot necessary!"
"The problem is most likely a mix of static buildup and accidental input rejection algorithms. As algorithms ‘learn’ your taps and swipes, the occasional spurious static electricity confuses the machine learning model. As you continue to use your iPad, the model mistakenly learns to ignore some normal swipes and taps.
Hard reset (hold Home+Sleep button) alleviates the problem temporarily. Limiting refresh rate, helps temporarily as well. These problems seem to appear more frequently on larger 120hz devices due to necessarily more aggressive accidental/spurious input rejection. Apple should be able to address this via software update.
The static electricity problem seems more pronounced in high humidity, but this is anecdotal."
