Keyboard glitching and screen hanging after recent update

Hi huzaif160,

Thanks for contacting Apple Support Communities!

We understand that your iPhone stops responding after installing the latest update.

Have you noticed if this happens within specific apps or while you're connected to a specific network?

If you feel that it's app related, you can reference this article which will show you how to troubleshoot the app: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

If it happens with all apps, check out the troubleshooting steps outlined here to help you to isolate this behavior further: If your iPhone or iPad is running slow - Apple Support

"Look at your battery health

All rechargeable batteries are consumable components that become less effective as they chemically age. Over time, the rechargeable batteries in all iPhone and iPad models will diminish in their capacity and peak performance and will eventually need to be replaced. iOS can show battery health and recommend if an iPhone battery needs to be replaced. Go to Settings > Battery and tap Battery Health. Battery Health is available only on iPhone.

• A touch screen that responds to taps incorrectly can make your device seem slow. If you think that your touch screen isn't responding correctly, try restarting your iPhone, iPad, or iPod touch. If that doesn't work, and the issue occurs in the same area of the screen in multiple apps, you might need to contact Apple Support.
• If you tried these tips and your iPhone, iPad, or iPod touch is still slow or continues to freeze, contact Apple Support."

Take care!
