[Phone] Why do I not get notification of system update (FOTA)?

1. To prevent too many users updating firmware at the same time, ASUS delivers notifications to the users in groups. If the users want to check if the device firmware is the current latest version, please tap "Check Update" function in [Settings] -> [About] -> [System update] or go to the ASUS official website to download the latest version firmware.

About how to update device firmware, please refer to FAQ on official website: How to update firmware on my phone?

2. If your phone is rooted or has wrong version (sku), you will not receive notifications of system update (FOTA).
