Hi hamode.97.mh,
If possible, please show us an original photo of the camera problem.
Please also provide us the information as below:
Rear/front camera, the ambient brightness, which camera mode, what camera settings( Screenshot the preview before you take the picture. Also, access the camera settings by tapping the upper right three dots and screenshot this page.)
Please upload the original photo to ASUS WebStorage (https://www.asuswebstorage.com/navigate/) and share the link with us.
For battery problem, is the battery performance poor when using the phone or not using the phone?
Thank you 🙂
