iPhone flash does not work may be caused by several common problems. First check whether the flash option is missing in the Control Center, go to Settings > Control Center to add this feature. Secondly, the flash is turned off immediately after it is turned on, which may be due to the overheating protection mechanism, so you need to wait for the phone to cool down and avoid using high-brightness third-party applications for a long time. If the flash cannot be turned on at all and there is no software problem, it may be hardware damage such as damage to the camera module or water inlet. It is recommended to contact Apple support or authorized repair points for processing. Restarting the phone can also try to resolve software failures.

If your iPhone flashlight isn't working, it's probably one of a few common issues — and most of the time, it's something you can fix quickly. Whether it's a simple settings mix-up or a hardware problem, let's go through the likely causes and what you can do about them.

Flashlight Option Missing in Control Center

One of the most frequent reasons people think their flashlight isn't working is that they can't find the option in the Control Center. If that's your issue, it's likely just not added to your controls yet.

• To fix this, go to Settings > Control Center and look for the Flashlight option. If it's not there, tap the green plus icon next to it.
• Once added, swipe down from the top-right corner (on iPhones with Face ID) or swipe up from the bottom (on older models) to open the Control Center and check if the flashlight button appears now.

Also, make sure you're not accidentally using 3D Touch or Haptic Touch too hard — sometimes pressing too firmly might bring up other options instead of toggling the flashlight directly.

Flashlight Turns On Then Off Immediately

Sometimes you tap the flashlight icon and it turns on briefly, then shuts off by itself. This usually happens as a safety feature when the LED gets too hot.

• iPhones have a built-in thermal protection system. If the phone has been used heavily (like taking videos or playing games), the flashlight might shut off to prevent overheating.
• Let the phone cool down for a few minutes before trying again.
• Avoid using third-party flashlight apps that keep the light on full brightness for long periods — they can heat up the phone faster than the stock app.

This behavior isn't a malfunction — it's designed to protect your phone's components.

Physical Damage or Camera Module Issues

If none of the above applications and your flashlight still won't turn on at all, the issue could be hardware-related.

• A cracked back camera lens or water damage near the flash can cause permanent or intermittent failure.
• Try turning on the flashlight through the Camera app — sometimes the dedicated Camera flash works even if the standalone flashlight doesn't.
• If you recently dropped your phone or exposed it to moisture, that might explain the sudden failure.

In these cases, Apple Support or an authorized repair shop would be your best bet. It's not something you can fix yourself without opening the phone.

If you've checked the Control Center, ruled out overheating, and suspect no physical damage, try restarting your iPhone — sometimes a quick reboot clears up software glitches. If it still doesn't work, it's probably time to get it looked at.
