    Hi bernariz09

    To update the system, you may try Auto Update or Manual Update.

    1. Auto Update (Easier Way)

    Settings>System>System update

    *Tap the 3 dots on the top row of "System update">Auto-update settings, for related settings

    2. Manual Update (Normally be used in cross-Android firmware update or rooted/unlocked device)

    Download the firmware file into the root directory, aka the outermost place, of the internal storage>Reboot>Tap the "system update" notification

    *To perform cross-Android firmware update, please backup the device data first.

    However, which firmware version should I choose?

    Each firmware version will optimize the system stability from the previous firmware version. Since right now you are in the last version Android 8 (Oreo), you can try to upgrade to Android 9 or Android 10 beta version. if you still prefer Android 8 interface/system design, you can downgrade from Android 9 to Android 8 by downgrade file on Firmware Spot with SD card.
