How to install beta via OTA?
  1. Enable Beta Updates (Settings>General>Software Updates>Beta Updates)
  2. Check and sign into the right Apple ID to access beta
  3. Select which beta you would like to receive (Public/Developer)
  4. Hit "Back" and pull down to refresh
  5. Do an encrypted backup or iCloud backup before installing the beta from release build
  6. Install the beta
If you no longer wish to receive beta updates:
  1. Turn off the Beta Updates (you can also sign out of your Apple ID to unlink your developer account)
  2. Wait for the next public release or follow the guide below to install the IPSW release build
Troubleshoot: Sometimes, the beta update will not show so you may need to enable/disable Airplane Mode or restart your device before rechecking for update.

How to install beta via IPSW on Mac?
  1. You will need to install either Xcode beta or MobileDevice.pkg which can be extracted from the Xcode beta (tap with two finger or right click to Show Package Content>Contents>Resources>Packages>MobileDevice.pkg - this will work on older Macs that do not support the latest macOS or Xcode beta)
  2. Do an encrypted backup in Finder in case you need to restore your device
  3. Hold down Option + Check for Update and select the appropriate IPSW file for your device (whether you're updating to a newer/beta firmware, reinstalling the same firmware or downgrading to previous firmware while retaining all your data) downloaded from Apple using your free developer account. Note: You must have an active internet connection as it will check the IPSW signing status before it will proceed with the update.
  4. Enter your iPhone passcode once prompted to proceed.
Notes/Tips:
  • Always keep a backup in case you need to restore your data if you restore your device
  • It may be better to close all apps before installing the updates and/or turn off your device for about a minute or restart a few minutes after your device is updated
  • You can also manually select the IPSW if you are restoring your device using Option + Restore iPhone. Restore will wipe all your personal data which you will need to restore your backup either using iCloud backup or Finder/iTunes backup
  • You do not need to install the MobileDevice.pkg from each Xcode beta version unless Finder does not recognize the new iOS beta
  • There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
  • If you receive a new iPhone, you can connect to Mac to update or restore your device to the latest iOS before setting up your device.
  • You can also use the Recovery Mode/DFU to update or restore your device by manually selecting IPSW

Mine works properly. Try changing your screen zoom setting, then change it back to see if that fixes it.

It works for you when you pick a DIFFERENT photo for the Home Screen not in combination with a Lockscreen? Doesn’t work for me on iPhone 12 or iPhone 15 Plus. It did work on the 17.2 beta. Also, it does work when you select a new photo for your lockscreen in combination with the Home Screen but not if I select a different photo for the Home Screen afterwards

Ah okay. I don't typically use a different home screen photo. At least it will be fixed in 17.2.

Th Bug with adding Passkeys from Apps to Third Party Apps (like 1Password) is still not working. Glad I heard that with iOS 17.2 it will be fixed.

What WiFi standard are you using?
What frequency are you using most of the time?
What type of problem are you experiencing?
What phonemodel are you using?
Are you using any other network services such as VPN?

So far I like this "fix" (update)...Iphone 15 PM
1--Carplay NOW works on calls and connects rather quickly.
2---Battery life is better
3---WiFi connects quickly (I never had the WiFi staying connected problem--But I did with my Ipad )

Is there a problem with the phone bricking? I think my friend is teasing me about his relatives phones bricking after updating.

So did iOS 17.1.2 fix the WiFi connectivity issue or not? It still didn’t do anything for my iPhone SE’s WiFi. I still have to disconnect, then connect before my WiFi works. Guess iOS 17.2 is the one that will do it …
