Cause 2. Conflict with iPhone software

This is also considered a major cause of iPhones suddenly not displaying. Installing too many apps can interfere and conflict with the software. So, after the screen blackout, try pressing Home + Power simultaneously to restart the iPhone. Then, try deleting some of the installed apps. If the issue persists, try restoring the iPhone to reinstall the software.

Cause 3. Accidentally entering DFU mode

This issue often manifests as the iPhone screen staying black but still receiving calls and messages normally. When plugged into iTunes, it's still recognized. This indicates that the device has entered DFU (Device Firmware Upgrade) mode – a mode used for firmware upgrades. The solution when in DFU mode is to leave the device untouched for 2 to 3 days without charging. Afterward, charge for 15 to 20 minutes, connect to iTunes, and follow the instructions to Restore iPhone by entering DFU mode on the iPhone to update to the latest software.
