Why does my screen keep going black on my iPhone?

When all else fails, professional help is advised. Consult Apple Support or visit an authorized repair center. They can run detailed diagnostic tests to pinpoint whether the issue stems from hardware or software. This ensures an accurate assessment and a reliable fix.

In my experience, the battery can be a hidden culprit. Degraded battery health can cause random shutdowns or screen blackouts. To check battery health:
– Navigate to Settings.
– Tap on Battery.
– Tap on Battery Health.
If your battery needs service or the maximum capacity is low, replacing it might fix the black screen issue.

Lastly, check the accessibility settings to prevent any potential misconfigurations causing the problem. For example, disable Color Filters:
1. Open Settings.
2. Tap Accessibility.
3. Select Display & Text Size.
4. Ensure Color Filters is turned off.
Misconfigured accessibility settings can sometimes lead to unexpected screen behavior.

A hard reset can sometimes clear temporary software glitches:
– For iPhones 8 and newer: Quickly press and release the Volume Up button, then the Volume Down button, and finally hold the Side button until the Apple logo appears.
– For iPhones 7 and 7 Plus: Hold the Volume Down button and the Sleep/Wake button until you see the Apple logo.
– For older models: Hold the Sleep/Wake and Home buttons simultaneously until the logo appears.

Sometimes, iOS updates introduce unintended bugs. If you’ve recently updated your firmware, you might need to update again or even rollback. Check for new updates:
1. Go to Settings > General > Software Update.
2. Install if an update is available.
If that doesn’t help, try backing up your iPhone and consider a factory reset as a last resort.

Resetting all settings might help if rogue settings are in play. This action does not erase data but resets system settings:
1. Go to Settings.
2. Tap General.
3. Scroll down and tap Reset.
4. Select Reset All Settings to restore defaults without losing personal data.

Review your Display & Brightness settings, as sometimes the Auto-Lock feature can be overly sensitive. Check the settings:
1. Open Settings.
2. Go to Display & Brightness.
3. Check the Auto-Lock setting and tweak it if necessary.
Ensure it’s set for at least 1-2 minutes to avoid the screen turning off prematurely.

Water damage can be a silent cause of these problems. If your iPhone has encountered moisture or been in a humid environment, do the following:
– Power off your device immediately.
– Place it in a bag of uncooked rice or use silica gel packets to absorb moisture.
– Leave it there for a full 24-48 hours before turning it back on.

First, let’s check for potential software issues. Sometimes, apps can cause the screen to go black if they’re misbehaving. Here’s what you can try:
1. Close all open apps by swiping up from the bottom of the screen and pausing.
2. Swipe right or left to find apps, then swipe up to close them.
If the issue resolves after this, a specific app might be causing the problem.

Consider cleaning the screen. Often overlooked, dust or dirt can obstruct the proximity sensor located at the top of the screen. A malfunctioning sensor might cause the screen to go black unpredictably. Clean it with a soft cloth, and then test by making a call and covering the top area with your hand. If the screen stays black even after cleaning, a hardware issue might be more likely.
