Iphone 15 lock screen delay ( wake up ) IOS 17.1 problem

I've had this problem with previous phones. You might want to do a manual restart on your phone. That has been a good fix for me in the past.

iPhone 15 Manual Restart Instructions

(iphone 15 pro max - ios 17.1.1 )

YES! I am having the same problem and surprisingly i first noticed it on ios 17.1.1 , sometimes it takes me 4-5 taps for my iPhone to actually register that I am tapping it. However I have noticed it get better and not do it as much some days it doesn’t even do it even if I want it to- thankfully I have videos of it doing it if I ever need to show apple. and I have done all of the basics; and I don’t have tap duration on(apple said that they have seen the problem but with tap duration) I have tried force restarting my device, volume up volume down hold till apple logo, updating apps, turning tap to wake off and back on again(even though it was on in the first place) raise to wake off and back on again, my diagnostics pass the hardware test every time and my system software seems to be pretty stable. I still have yet to put this phone in recovery mode to see if it fixes the issue - how is the issue coming for you?

Same problem. I have completely disabled automated focus. And its working fine so far.

For me if i don’t personalize lock and home screen all work well, so for the moment the fix is this

So hope for 17.2, I fix this with no personalization of lock screen

I have the same issue with my iPhone 15 Pro Max. Restarting the device temporarily fixes the issue. Hope it will be fixed on the next update.

Changing the background solves the problem

Yes with ios 17 you need a restart every day if you don’t want to see these glitches all the time. It wasn’t this way in ios 15. It never needed a restart.

Same issue here. When waking iPhone by touching the display or pressing the sleep/wake button there is a one second delay. Restarting iPhone temporarily resolved the issue.

iOS 17.1 - iPhone XS

Same for me, I just got the brand new iPhone 15 pro and feel different from my iPhone 13 screen tap and screen wake-up speed.

After restarting it is gone for some time.

Still present on iOS 17.2.1. A restart seems to fix the issue for a couple of days though. And i guess a wallpaper without depth effect helps. Hope Apple fixes this soon. Quite annoying really!

The issue still persists in iOS 17.3. A restart solves it for a day or so. Anybody found a fix yet? It’s getting super frustrating now.

Since I updated my iphone 15 pro to IOS17.1, I noticed that when I tap the locked screen or pick up the phone, the screen takes a while to wake up. Turning off the device or restarting it only improves the problem for a few hours. Nothing works, I hope they improve this quickly, it's very annoying

I have the same bug as well and I just got my new iPhone 15pro max. When my screen dimmers and I tap the screen to wake it up, it takes a 1-2 seconds to light up. As well as when it’s in the Lock Screen. And it happens here and there. So it’s a iOS bug issue.

Any iOS update that you install, takes a couple of days to settle in your phone. So you won’t notice a different right away just miner bugs caused by the iOS working in the background. I hope Apple fixes the minor hiccups and we don’t experience the same issues we did with the iPhone 14 Pros.
