Facing problem top left corner touch iphone 14 pro

Greetings Sandork,

Thanks for posting in Apple Support Communities. We'd like to assist you with verifying if this issue is related to the hardware or software on your iPhone 14 Pro. The following steps may help resolve this behavior or allow us to get to the root cause of it:

• Close the app to see if that helps correct the issue. This is a great step to take when an app is not responding.

1. From the Home Screen, swipe up from the bottom of the screen and pause in the middle of the screen.

2. Swipe right or left to find the app that you want to close. 

3. Swipe up on the app's preview to close the app.

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

• If you have a case or screen protector remove them to see if that helps.

• Restart your iPhone. This helps to refresh your phone and the software:

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

Let us know if this help.

Best wishes!
