Unlike regular OTA updates from your Manufacturers, the regular patch updates will be handled by Google After you updated to Android 10 version. It can be done using your Google Play App. If you have Custom Skin OS from your Manufacturer, Google will not change the UI. They will handle only Patch updates. This is one of the most critical steps taken from their side. It will help all the users who are tired of their Manufacturer Late updates.

Other improvements and changes
- HEIF Image, Monochrome Camera Support.

- Contaminant Detection- If any moistures are in your USB Ports, your mobile will alert you.
If you are in Stock firmware, Use the Internal memory update method. It is comfortable and safe; You can update like a Regular OTA Update. But if you were already using Rooted devices, You can try TWRP based Method. Don’t download any third-party apps; sometimes, it may trigger the updates process. There are a lot of new Gestures available in this Update, try them also. In my opinion, Asus Zenfone 5Z near Stock Android is better to compare with some other Custom Skin OS. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
