How to manually check update in Asus Zenui

You can update your Asus Zenfone devices to receive VoLTE support. If you didn’t receive any update, try checking out manually. To check for updates manually, Go to Settings App in your device > System updates & tap on “Check updates”. Most of the time OTA updates take time to completely reach to every devices. So if you’re not able to update, you need to wait for 1-2 days to receive the update. If you really want the update as soon as possible, you can search if someone has got the OTA link so that you can install it manually though Asus recovery.
