Wavy lines with apple pencil on iPad (7th Gen)

Welcome Javier,

According to your post, you have issues drawing straight diagonal lines with the Apple Pencil and iPad. We'll do our best to help out with this.

It sounds like this issue may be related to a case or screen protector. It could be that the case is too tight for the iPad model. If you remove these, does the issue persist?

Have you had a chance to try out steps in: If the screen isn't working on your iPhone or iPad - Apple Support

If your screen is too sensitive or responds intermittently to touch

1. Restart your iPhone or iPad.

2. Make sure that your screen is clean and free of any debris or water.

3. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.

4. Remove any cases or screen protectors.

If part of your screen doesn't respond, responds intermittently, or responds even when it's not touched, contact Apple Support.

If your screen is cracked or shattered

Contact Apple Support

Does the issue persist if you use the Apple Pencil with another iPad? Does it occur when you draw using your hand and no the Apple Pencil? Does it occur in a specific app? That would help us narrow down the issue further.

Hoping to hear back, take care.

Hey Javier,

If the above didn’t lead to a resolution, go through the following steps:

• Make sure iPadOS is up to date: Update your iPhone, iPad, or iPod touch.

• Fully charge your Apple Pencil.

• Remove any case and screen protector from your iPad.

• Unpair, restart, then pair your Apple Pencil and iPad.

If the issues continue after this, reach out to Apple Support at the following link to look further into this with you:

Hey Javier,

On the Apple Pencil, is the tip screwed on all the way? We ask because if it isn't screwed on tightly, it can cause erratic behavior when using the Apple Pencil with an iPad. We'd confirm this before you visit the Apple Store.

If the issues persists, despite all of the suggested steps; then it would be best to have the Apple Pencil inspected at a local Apple Store or Apple Authorized Service Provider. Bring your Apple Pencil, the original receipt (if you have it or get a copy from original place of purchase), and a photo ID with you to the store. Select your region and search nearby for locations: Find Locations

Hoping this gets it solved, cheers.

Was your issue got resolved? Im having an issue too with iPad Pro 12.9 M1 and Pencil 2.
