How To Fix Auto Lock Greyed Out on Apple iPhone 12 Pro Max

Auto-lock on iOS devices serves multiple purposes - it conserves battery life, secures your data, and more. But have you encountered the Auto-Lock greyed-out dilemma, fixed at 30 seconds? When this setting becomes inaccessible, it limits your control over screen timeout.

Read on if you’ve encountered a similar problem on your iOS device. In this guide, we’ll explore the possible reasons and offer steps to fix Auto-Lock greyed out on iPhone and iPad devices. If force restarts or settings resets haven’t worked for you, we’ve got alternative solutions. Let’s get started.

Part 1: Why Is Auto-Lock Greyed Out on iOS Device?

There are a few reasons why the Auto-Lock might be greyed out on your Apple iPhone 12 Pro Max or iPad device, preventing you from adjusting the duration. Here are the most common culprits:

Low Power Mode

When you activate Low Power Mode on your iOS device, you might notice the screen automatically locking after 30 seconds of inactivity. This quick sleep setting, implemented to minimize power usage, explains why the Auto-Lock option appears greyed out and inaccessible.

Screen Time Restrictions

Screen Time restrictions can impact Auto-Lock. For instance, if your downtime schedule blocks all apps, the screen locks itself, even if the Auto-Lock timer hasn’t run out.

MDM Profile Restrictions

If the Auto-Lock is greyed out on your iPad or iPhone and you use it for work or school, a Mobile Device Management (MDM) profile might be the reason. This profile restricts settings, including Auto-Lock. To fix this, contact your IT administrator and ask if they can adjust the MDM profile settings.

Alright, you know the possible reasons why the Auto-Lock option is not working on your iOS device. Still, you might be wondering how to fix the Auto-Lock greyed-out issue. Below are several ways to get your iPad or iPhone Auto-Lock working normally again.

Fix No.1: Disable Low Power Mode

Your iPhone Auto-Lock greyed out because Low Power Mode limits background activities, including the Auto-Lock option. In this mode, you cannot change the Auto-Lock settings. Turn off Low Power Mode to fix this issue and choose your preferred timeout. Here’s how:

• Step 1: Go to your Apple iPhone 12 Pro Max or iPad’s Settings app.
• Step 2: Scroll down and tap Battery. It will show you your device’s battery usage and available settings.
• Step 3: Turn off the Low Power Mode. Now, the greyed-out Auto-Lock option in Settings should be available again.

Low Battery Mode can stretch your battery life further. But if you need your screen to stay on longer, like while reading an article or watching a video, you can turn it off. It lets you adjust the screen timeout in Settings so it stays awake for as long as you like.

Fix No.2: Check Screen Time Restrictions

You’ve ruled out the Low Power Mode, but the Auto-Lock greyed out on iPad or iPhone remains. If Low Power Mode isn’t causing the problem, your screen time settings might be the issue. Some app restrictions can limit your screen use to specific times, causing it to lock automatically. Resolve this by removing limits, such as downtime and app restrictions, or turning it off.

• Step 1: Open the Settings app on your iOS device.
• Step 2: Go to Screen Time, then scroll down.
• Step 3: Tap Turn Off Screen Time.

Fix No.3: Remove MDM Configuration Profile

A configuration profile is a file that contains settings and restrictions that can be applied to an iOS device. Organizations, schools, or IT administrators often use it to manage devices remotely and enforce specific configurations. Once installed, the settings within a profile override the Apple iPhone 12 Pro Max device’s default settings. It can include restrictions related to security, network access, app usage, and more.

Since an MDM configuration profile causes limitations, like the greyed-out Auto-Lock on iPad, removing it can be the solution. Doing so frees your iOS device from external settings imposed by the profile. Then, it could allow you to adjust the Auto-Lock time setting as you normally would.

• Step 1: See the configuration profiles you installed on your iOS device.

• Go to Settings> General > VPN & Device Management on your Apple iPhone 12 Pro Max.

• Go to Settings> General > Profiles & Device Management on your iPad.

• Step 2: Select the configuration profile you need to delete.

• Step 3: Tap Remove Profile, enter your device passcode, then tap Remove.

Fix No.4: Remove Network Settings Installed by MDM

Businesses often use Mobile Device Management (MDM) to remotely manage their employees’ iPhones and iPads. MDM lets IT admins push software updates, restrict apps, and remotely wipe a lost device. This keeps corporate data safe and devices under control, whether the company or the employee owns them.

If you’re having trouble with a greyed-out Auto-Lock timeout setting, disassociating your device from MDM might be an option. But remember, this is a big step. Make sure you follow your company’s authorized procedures to avoid unintended consequences.

If your IT team gives the green light, you might also be able to remove the network settings installed by MDM. Just proceed with caution, as messing with these settings could lead to instability or data loss. Here’s how:

• Step 1: Open the Settings app on your iOS device.
• Step 2: Navigate to General > Profile or VPN & Device Management (or a similar section).
• Step 3: Select the management and tap Remove Management.

If the option is unavailable, only the person who used Apple Configurator 2 or handles your company’s mobile device management platform can remove it.

Fix No.5: Use Dr.Fone To Bypass MDM Lock Without Data Loss

Unfortunately, manually removing profiles can be tricky, especially if they’re associated with MDM, Apple School Manager, or supervised configurations. These often require the removal of passwords, admin privileges, or complete data wipes. But there’s good news. Wondershare Dr.Fone - Screen Unlock (iOS) provides a simpler and safer solution.

Part 2: How to unlock Apple iPhone 12 Pro Max with iTunes?

Just like Dr.Fone - Screen Unlock (iOS), you can also use iTunes to fix the Apple iPhone 12 Pro Max won’t unlock the problem. Though, the solution is not as user-friendly or effective as Dr.Fone’s. You need to take care of some prerequisites before following this technique. Also, to unlock your device with iTunes, you need to put your phone in recovery mode. The key combination would slightly vary among different iPhone models.

Prerequisites:

1. Just like Dr.Fone, this technique will only work if the Find My iPhone service is not enabled on your Apple iPhone 12 Pro Max. You can go to iCloud’s website and disable the feature under the “Find my iPhone” option.
2. Also, you need an updated version of iTunes to make it work. This is because an older version of iTunes won’t be compatible with iOS 13. Go to the iTunes menu, check for updates, and follow the simple on-screen instructions to update iTunes.

Step 1. Put your phone in the Recovery Mode

After meeting the basic prerequisites, you need to put your Apple iPhone 12 Pro Max in recovery mode by following these steps:

Part 4: Does the tricking Siri method unlocks Apple iPhone 12 Pro Max?

Lately, there have been a lot of articles about this method. As an expert, I would like to clear the air – you can’t trick Siri to unlock your Apple iPhone 12 Pro Max. In some iPhone models, we could trick Siri into unlocking our device and entering the home page without bypassing the lock screen. The trick worked for a few devices and was an instant hit as it retained our data while unlocking our device.

It was a loophole from Apple’s end, which was present in iOS 10.3. Therefore, if your device is still running on iOS 10.3, then you might give it a try. Sadly, the only way to bypass an Apple iPhone 12 Pro Max that won’t unlock now is the restore your device (erasing its existing content). Since Apple iPhone 12 Pro Max currently runs on iOS 14, the trick won’t work.

5.1 Enable Find my iPhone

This is the most important thing to do to protect your phone from being misused. As you can see, a perpetrator can only unlock your device if the Find my iPhone service is turned off. Therefore, you should make sure that the feature is on. To turn it off, they would need to access your iCloud account first, which would require a lot of effort.

Just go to the iCloud settings on your phone and turn on the “Find my iPhone” service. Also, enable the “Send Last Location” feature. This will automatically send the last location of your device whenever its battery would be critically low.

5.2 Use Find my Friends

Just like Find my iPhone, Find my Friends is a native location-sharing feature developed by Apple. You should have at least 2-3 people with whom you are sharing your location. Go to the Find my Friends app on your device, enable the location sharing feature, and add your close friend and family.

In this way, if your device is stolen, you can track it immediately with the help of your friends.

5.3 Enable two-factor authentication

Your iCloud account should be protected at any cost. By infiltrating your iCloud account, anyone can erase your phone remotely. It is recommended to enable the two-factor authentication on your account to strengthen its security. Go to your device’s Settings > Apple ID > Passcode & Security and enable the two-factor authentication feature.

5.4 Erase data after failed unlocking attempts

This is a crucial setting that you should enable to protect your data from unknown perpetrators. If someone tried to unlock your device and get 10 failed attempts, your data would automatically be erased from your phone.

Go to Settings > Face ID & Passcode and turn on the “Erase Data” option. Though, if you have enabled the option and have forgotten the passcode of your phone, then you should be alarmed.
