How do I fix iPhone screen too bright or dim on iOS 18?

So, your iPhone screen is acting up? Too bright? Too dark? I’ve been there. Let’s fix it. Here’s what you need to know in simple, easy-to-follow steps. Ready? Let’s get started.

Solution 1: Check the Control Center First

1. Swipe down from the top right corner of your screen.
2. You’ll see a brightness slider. Adjust it manually.

Solution 2: Turn Off Auto-Brightness

1. Open the Settings app.
2. Tap Accessibility.
3. Now, go to Display & Text Size.
4. Scroll down and toggle Auto-Brightness off.

Auto-brightness changes with room lighting. Let’s stop that.

Solution 3: Update Your iPhone’s Software

1. Head back to Settings.
2. Tap General, then tap Software Update.
3. If there’s an update, install it. Updates fix bugs.

Solution 4: Check Zoom Settings

1. Go back to Accessibility.
2. Find Zoom.
3. Toggle it off.

Sometimes Zoom messes with brightness, so this might help.

Solution 5: Disable Low Power Mode

1. Open Settings again.
2. Scroll down to Battery.
3. If Low Power Mode is on, turn it off.

Low Power Mode saves battery by dimming your screen. Let’s fix that.

Solution 6: Turn Off Night Shift

1. In Settings, go to Display & Brightness.
2. Find Night Shift and disable it.

Night Shift adjusts your screen’s color and brightness to reduce blue light. Could be messing with things.

Now, try adjusting your brightness again. If it’s still not working, time for a restart.

Solution 7: Force Restart Your iPhone

1. Press and quickly release the Volume Up button.
2. Do the same with Volume Down.
3. Now, hold the Side Button until you see the Apple logo.

Don’t worry. This restart won’t delete any of your stuff.

Solution 8: Reset All Settings

1. In Settings, go to General.
2. Tap Transfer or Reset iPhone, then choose Reset All Settings.
3. Enter your passcode if it asks.

Resetting won’t erase your data. But it might clear whatever’s stopping the brightness from adjusting.

Now, try adjusting the brightness. That should do the trick.
