Can we determine OTA-Upgrade without Wi-Fi?
Yes, but it's not recommended. Updates weigh a lot, and when using mobile internet, you can spend all the traffic or interrupt the download due to an unstable connection. If there's no other option, make sure you have unlimited rates.
Why? OTA-Updates have disappeared some functions?
This can happen if you install firmware from another region (e.g. Chinese instead of global), some features (e.g. Google Assistant or Netflix in HD) can be disabled, and the solution is to return the original firmware.
How to turn off the automatic OTA installation?
Go to Settings β†’ About Phone β†’ System Update β†’ Three Points β†’ Settings and turn off the option Autoboot via Wi-Fi. However, we do not recommend doing this, as you may miss important security patches.
