Sorry for the delayed reply. Restoring photos from a completely unresponsive Pixel 4 XL can be a challenging task, but there are several steps you can try to recover your photos. Here's a guide to help you:
Check for Physical Damage:
Make sure that the unresponsiveness is not due to physical damage, such as a broken screen or water damage. If the screen is damaged, you may need to get it repaired before proceeding with data recovery.
Use a USB OTG Adapter:
If the phone is unresponsive but still powers on, you can try using a USB On-The-Go (OTG) adapter to connect a USB mouse to your Pixel 4 XL. This may allow you to control the phone and access your data, including photos. Once you have control, you can transfer your photos to an external USB drive or another device.
Seek Professional Help:
If the above methods don't work, and your Pixel 4 XL remains unresponsive, you may need to seek professional help from a smartphone repair shop or data recovery specialist. They may be able to recover your photos, but it can be a costly option.
Hope this will help.
