I sm confused.

There are many 4th gen iPad models, now.

What year and model iPad do you, actually, have/own?

Can you, please, confirm what year and model iPad do you have/own?

The “A” model number can be found on the aluminium back of your iPad, in very small print, right under the larger bold print “iPad” on the back of the iPad.

What iOS/iPadOS version is this iPad, currently, running?

Please try and attempt to answer all questions asked.

Thank You.

Yes, if it is a manufacturer defect.

Have it inspected at an Apple Store or AASP (Apple Authorized Service Provider). Apple technicians will judge.
