iPad unresponsive to touch

Start here >>> If the screen isn't working on your iPhone or iPad - Apple Support

If your iPad is unresponsive, connect your iPad to its Power Adapter and allow the iPad to charge undisturbed format least an hour. Then, while still connected to external power, try a forced-restart:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

If iPad still doesn’t turn on, or if it gets stuck during start up, see the Apple Support article If your iPhone, iPad, or iPod touch won’t turn on or is frozen. Or if your iPad isn’t working correctly after you restart it, see the iPad Support website.

If you continue to experience difficulties, you will need to seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad:

This is NOT something you are going to want to read, but these are the facts/issues, as I know them, for the past almost 4 years.

The intermittent, unresponsive touchscreen issues with higher priced, larger screen iPad Pro and iPad Air models are a well known and well documented, here, in the iPad support communities.

Any iPad model with a 10.5 inch screen seem particularly susceptible to this Intermittent,unresponsive touch screen issue.

This still affects a small, but continually growing minority of random 2017 through present iPad Pro and iPad Air models and its user base.

Now, after over 4 years of this nonsense, there is still no confirmed cause and fix/solution from Apple.

NONE!

Getting one of these defective units is very random and is ONLY one of a small handful of issues going on with higher priced, larger screen iPad models that has prevented me from purchasing a new iPad Pro or new iPad Air for the past 2-3 years.

Apple and Apple support have no real fixes or solutions to this issue and, most likely, at this very late date, never will.

Again, Sorry.

You can continue to try simple hard resets of your iPad year and model, but this quick fix is, usually only a temporary solution.

For iPad models with a Home button, do a simple hard reset of your iPad by holding down both the Home and sleep/wake/power button simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

OR

For much newer design iPad models, without a Home button, try the new simple hard reset procedure for the new 2018/2020/2021 iPad Pros, 2020 iPad Air 4 and 2021 iPad Mini 6 models.

1. Press and release the volume up button.

2. Then immediately press and release the volume down button.

3. Then, press and hold the single sleep/wake/power button You will see the Slide to Power off button, but keep on holding down the power button until you see the Apple logo, then let it go.

Once you have performed all the steps, wait for a few seconds and your 2018 iPad Pro will boot up completely to the iPad Pro’s Lock screen.

If you have a screen protector on this iPad Pro, remove it as the screen protector makes the touch screen and Pencil experiences worse.

Also, try removing your iPad's case ( it maybe too tight a fit ) and try using your iPad without it to see if this helps, or not, with your iPad touchscreen issue/s

There is absolutely no solution/s to these later iPad Pro/iPad Air touch screen issues.

Apple support can only offer superficial, “band-aid” bandage-like advice/fixes/solutions.

You can contact Apple support, but your iPad Pro/later iPad Air model maybe too old for Apple to offer any type of free or in-warranty iPad replacement and Apple will ONLY offer “band-aid“-like advice/fixes/solutions to this issue.

Apple support is pretty much clueless to this issue and Apple, itself, has never, publicly, acknowledged this issue or issued any type of device recalls.

This is something you probably didn't want to learn, but doesn't change any of the currently known facts.

So Sorry & Best of Luck to You!
