iPhone 15 - Freezing and Glitching Issue

Update: I've discovered a potential solution that appears to alleviate the app crashes: resetting my network settings. It's puzzling why this would be necessary on a brand new phone. However, I suspect the app crashes might have been due to network timeouts and connection failures. Judging by some of the other comments I’m not sure this will work for everyone but wanted to mention it.

I had to reset my phone with a computer. Then when setting it up you can’t type in your iCloud account until the phone boots all the way up and it’s unlocked . So that it doesn’t restore from backup. This will install a brand new copy of Apple os on your device. This was the only thing that fixed my phone from doing this

I did the software update (ios 17.4.1.) and out of frustration i reinstalled my iphone as a last thing i could think of to do (back to factory settings and used my last icloud back up) and all issues where gone. Before this my iphone 15 max pro froze in most of my apps, gliched and i couldn't synchronize icloud or download documents.

maybe it will help someone else to do the same.

Hi Mo_Magic,

Since your iPhone is glitching and freezing, we recommend that you try the steps here: If your iPhone won't turn on or is frozen - Apple Support

To perform the recommended troubleshooting steps via the link above, complete the steps in the section below.

On your iPhone 8 or later, including iPhone SE (2nd and 3rd generation)

1. Press and quickly release the volume up button.

2. Press and quickly release the volume down button.

3. Press and hold the side button until you see the Apple logo.

4. If your phone doesn't turn on, follow these steps to check your hardware and charge your phone. You might need to charge for up to an hour.

If your iPhone turns on but gets stuck during start up

If you see the Apple logo or a red or blue screen during startup, try these steps:

1. Connect your iPhone to a computer. On a Mac with macOS Catalina, open the Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. Find out which macOS your Mac is using.

2. Select your iPhone on your computer.

3. While your iPhone is connected, follow these steps:

* On your iPhone 8 or later, including iPhone SE (2nd and 3rd generation): Press and quickly release the volume up button. Press and quickly release the volume down button. Then press and hold the side button.

We recommend the steps above because they will show you what to do if your iPhone is freezing.

Mine was doing similar took it to Apple Genius Bar (appointment ) it was because somehow the VPN was on. They turned it off and reset my phone, no more problems

It is hardware fault with some of these phones which only solved once the phone was replaced. I tried almost every solution in this thread and recommended by the customer service executives at Apple. The diagnostic repair was conducted but it still didn't work and I was asked to come the next day, but I persisted. In the meanwhile the phone just kept on glitching. It took too many hit and trials to get the backup of it. Right now I'm on replaced phone and seems like the problem completely gone. Only its running a bit hot is experienced but at least it just stays on. So far so good. Hope Apple acknowledges the hardware bug and quality control issue with some of these devices. Thanks all!

Mo_Magic,I have used this apple advised tip for clearing bugs- press ‘fast’ up volume then press ‘fast’ down volume let go quick then ‘fast’ press power button hold this in until you see apple logo appear then let go and wait for ph to prompt you then swipe up then you will be asked to punch in passcode. This has cleared up a lot of little problems. Sometimes more than once I do this. There will always be problems with the systems but this has helped me much. Do you have the iOS 17.0.3 update. That is designed to fix problems along with regular clearing the system might be the ticket for you?? Good luck on this it must be hard to handle spending so much and having this to work out. Try the above and add to your tool box.

This same issue just happene with my iPhone 15 Pro following the most recent iOS upgrade. This simple hack found on You Tube fixed it for me in seconds. Tap the volume up button, then tap the volume down button, and then hold the power button only ( the button on the opposite side of the phone from the volume buttons) down until the phone screen goes black and then you see the Apple logo appear. You’re only holding this one button but you have to keep it held until you see the Apple logo appear. That forced a reboot, and when my phone screen came back up, it was unfrozen. This problem seems to be hardware related. Perhaps a cache problem? It would be nice if an Apple Support person posted the cause, but more importantly, Apple, please fix it in your next software upgrade

I just traded in my 12 pro max for a 15 pro max. I experienced all that was shared about the hot temperature of the phone. As well as the freezing of the screens in the different apps. I called Apple, and I was told that I had to back up my new phone to my MacBook and wipe out the phone back to factory settings. They did this with me, and it seems to be working better. Sometimes, the apps can cause a problem.

I responded to this a few weeks ago, and what I found worked for all of these issues was to use Apple support to download all the contents of my iPhone. 15 pro max to my MacBook, and then do a reset with them. i no longer have the freezing problems etc..

To restart an iPhone 15 Pro Max,

1. Tap the Volume Up Button
2. Tap the Volume Down Button
3. Long press the Side/Power Button until Apple Logo.

I had the freezing and glitching for a couple days, but after updating ios to 17.1.1 it stopped happening — knock wood!

This actually worked, I soft booted the phone, didn’t work. I then reinstalled Facebook, didn’t work. I saw this post and reset my network connections… and it worked. Strange that turning off the network and using cellular didn’t work, but resetting the phones network at the bottom of general settings did the trick! Thank you!
