iPad screen experiencing ghost touch

Assessment, diagnostics and software fixes at an Apple Store are entirely free of charge. If instead you use an Apple Authorised Service Provider (AASP) there may be fees involved.

Unless you have no other alternative, a visit to the Genius Bar at an official Apple Store is your best option - an appointment being advised prior to your visit:

Only if a repair is necessary will potential costs and options need to be explored. If covered by warranty, costs for repair of replacement will be nothing. If you have benefit of an active AppleCare+ plan, costs will be limited to a small deductible fee.

In absence of an active AppleCare+ plan, an out-of-warranty repair (if needed) will obviously have an attached cost...

Issues of ghost touch, to which you refer, are occasionally reported here.

Given the steps to resolve the problem that you have already tried, you would be best advised to seek assistance directly 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 from Apple devices using the excellent Apple Support App. If not already installed, 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 you can (a) demonstrate the issue and (b) the technicians can hands-on test and assess your iPad. Here you will be in the best possible place to explore your available options:

Would it be free? Currently struggling on money and my research says that apple has a 1 year warranty. Does that mean the repair is free? It looks like a manufacturing issue since my IPad has been in perfect condition. I can't use my IPad at all.
