iPhone 17 Pro screen shuts down quickly and auto-lock setting is greyed out

It used to be that I could fix that by changing the screen lock time. Unfortunately, when I go to do that, it is unavailable (greyed out). Is there a way to get around this?

1. Is this your corporate/organisation/enterprise/School Management iPhone? Then please contact the system administrator of your corporate//organisation/enterprise/School Management
2. If it is your device, in that case, do you have any profile installed by your corporate/organisation/enterprise/School Management?
   1. Erase the profile added by you If you have installed a profile on your own --> Install or remove configuration profiles on iPhone - Apple ...
   2. Or please contact the system administrator of the organisation who provided the profile to you

A corporate profile installed on your iPhone could potentially be contributing to the inaccessibility of certain features. 

Here's why:

• Restrictions: Corporate profiles can have restrictions placed on apps and functionalities. These restrictions might be limiting some activity, causing it to be unresponsive or quit.
• Managed Apps: IT departments might deploy specific navigation apps through the profile, potentially blocking certain functions or features.
• Security Settings: Corporate profiles often have stricter security settings that could affect app or function behavior. This might be causing unexpected behavior of an App or functions.

Here's what you can do:

• Check with IT: The best course of action is to contact your IT department. They can explain the restrictions set by the corporate profile and see what is affected. They might be able to adjust settings or suggest alternative apps or features approved for corporate use.
• Look for App Conflicts: See if your IT department uses a different app through the corporate profile. Conflicting apps might cause crashes.

Additional points to consider:

• Even if the profile isn't directly affecting the function, it's still a good idea to check with IT. They might be aware of similar issues and have workarounds.
• While troubleshooting, make sure you prioritize safety. Don't fiddle with your phone. 

By working with IT and considering these possibilities, you can hopefully identify if the corporate profile is the culprit and find a solution that allows you to use the iPhone to your liking.

You may try some of these steps. Please check after each step...

1. Having too many apps open may cause this issue, as RAM is being used by other apps, leaving less memory available for proper rendering. Close an app on your iPhone or iPod touch
2. Overloaded system: Too many apps running in the background can cause stuttering. Refresh content in apps you're not actively using on ...
3. Storage issues: Low or fragmented storage can slow down the camera. --> Manage and Clear Storage on your iPhone a… - Apple Community
4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
5. If you're using a VPN, disable it and check if the error goes away. Go to Settings > General > VPN & Device Management and turn off any active VPNs. Disabling a VPN only from the iPhone settings may not completely turn it off. To fully disable it, you need to switch it off from the VPN service provider’s app or remove the configuration profile they installed. Only then is the VPN truly off, which can help if it’s causing issues with cellular or Wi-Fi connectivity.
6. Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
   5. 
7. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
   4. 
8. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Between that and the fact that it no longer corrects my spelling I am completely fed up with this thing!

For example: 

If your iPhone dictation consistently types "Kruse" instead of "cruise," here's how you can correct it:

1. Train the Dictation System
   1. Use dictation in a text field (like Messages or Notes) and say "cruise."
   2. When it types "Kruse," manually edit it to "cruise."
   3. Repeat this a few times. Over time, the dictation system may learn your preference.
2. Retrain Siri with your voice. Go to Settings > Siri (or Apple Intelligence & Siri). Tap Talk to Siri, then tap Off. Turn on “Siri” or “Hey Siri” again, then ...Change Siri settings on iPhone
3. Add a Text Replacement
   1. Go to Settings > General > Keyboard > Text Replacement.
   2. Tap the + button to add a new replacement.
   3. In the Phrase field, type "cruise."
   4. In the Shortcut field, type "Kruse."
   5. Now, whenever "Kruse" is mistakenly typed, it will autocorrect to "cruise."
4. Check Contact Names
   1. If "Kruse" is a contact in your address book, the system might prioritize it.
   2. Go to Contacts and check for any entries named "Kruse." If it's not needed, consider editing or removing it.
5. Reset Keyboard Dictionary
   1. If the problem persists, resetting the keyboard dictionary can help:
   2. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Keyboard Dictionary.
   3. Confirm the reset. Note that this will erase all custom words learned by the keyboard.
6. Enable Siri Pronunciation Feedback
7. If "Kruse" is related to Siri misunderstanding you, you can provide feedback:
   1. 1. Ask Siri, "Who is Kruse?"
      2. If Siri shows the incorrect suggestion, say, "That's not how you pronounce 'cruise.'"
8. Follow the prompts to correct the pronunciation.
