I cannot swipe to unlock my phone nor swipe to shut down phone. It appears to be locked so I can't use it

Hello ~ Try your restart this way…it’s a prior post by *Axel Foley*

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

Please try force restarting:

Force restart iPhone - Apple Support

Let's start with: Is this phone in Lockdown Mode? You would know, because you would have had to enable it. Chances are it is not ... so that leaves, at least, two possibilities:

1. Your phone is Activation Locked, or
2. The phone's display is damaged somehow.

Can you provide us with the details that led up to this issue?

Hello~ Thank you for posting back to let me know!! Great work on your part. I always force restart my iPhone after updating and if I am having an issue. Never hurts and often helps. Take care.

Did you try the "Force Restart" as per Libby101a's suggestion?

Katana! That worked. Thank you!!!!!! I thought I was going to have to go to Apple Store for service.

i can’t swipe up to unlock my phone, I’ve turned it off then on again, also tried taking sim out and back in. Is there anything else I can do?
