Android 10 for Asus ROG Phone 2 – New Features and Changes

Android 10 for Asus ROG Phone 2 - Screenshots

Android 10 is definitely a major upgrade from Pie as it brings a series of new features and changes to the phone. The first one that I would like to point out is the system-wide Dark Mode feature, which when turned on, will turn the complete system UI to dark colors and accents. The dark theme on your ROG Phone 2 may give you a marginal battery boost because of the equipped AMOLED display. It should also cause less strain on your eyes while viewing the phone’s screen in low-light environments.

Another notable feature is the new full-screen gesture navigation system that completely gets rid of the navigation buttons and relies on swipes/pulls. In Android 10, Google has added another feature based on Machine Learning that suggests replies and actions for message notifications.

The new privacy and location controls in Android 10 will give you more granular controls over the permissions required by apps. These are just to name a few, for the complete list of new changes and features in Android 10, please visit the official website.

According to the release notes published by Asus, the following are complete changelogs for this update, for both the Global and Tencent Editions of the ROG Phone 2.

Wrapping Up

Update: Since the initial rollout of Android 10, Asus has fixed a lot of issues to make the system more stable for daily usage.

Users who have already upgraded their ROG Phone 2 to Android 10 have some mixed opinions about it. Although there aren’t any major or a considerable amount of bugs, a few minor issues are already being discussed over at ZenTalk forums (See 1 & 2) and also at XDA.

If you do face any abnormal issues after manually installing the Android 10 update, you can try performing a factory data reset. According to one of the users in the thread linked above, doing a factory reset after the upgrade “was a massive improvement” for him.

However, if you do feel that Android Pie is overall more stable than Android 10 at the moment, then you can easily downgrade your ROG Phone 2 using the instructions in this guide.

Also, please consider reporting your discovered issues directly in the ZenTalk forums. This could help speed up the development process and you may also get to know of available fixes (if any) from the fellow users.

If you face any problems updating your phone using this method, or have any questions regarding the update itself, then please let me know via the comments.

    1. Hello Paolo. This could be because of two things:

      1) Either you did not place the full ROM package in the right location, i.e. in the root of your phone’s internal storage.
      2) Or, you’re using the wrong ROM. Make sure that you use the WW ROM if your phone is Global/Strix edition or the CN ROM if it’s Tencent edition.

      On a side note, did you convert your ROG Phone 2 from Tencent to Global edition? Or had it purchased from a seller in China?

  1. Comprei o meu Rog Phone 2 recentemente e percebi que ele não atualiza para o android 10 a minha versão é WW_16.0622.1906.19_0. Como devo proceder para atualizar? Mesmo baixando Pacote completo de firmware e colocando na memoria interna a mensagem que aparece é falha na atualização. Me ajude!

  2. I’m also getting the same error “system update failed” after following the steps. Mine is a Tencent CN device but a few months ago I switched over to the WW ROM. I wasn’t able to update the fingerprint/country at the time and I think that might be why I’m getting the error. Can I make the corrections now or do I need to do a factory reset and then start over?

    1. You’d need to start from scratch by following all the steps in the conversion guide. Once you have done it, you will be able to install the updates as shown here without any problems.

    1. Hi Leonardo. In most cases, this error would show up if you converted the Tencent Games edition to the Global edition of the ROG Phone 2, and the conversion didn’t go through properly.

      Could you please install the Device Info HW app from the Play Store and share a screenshot of the ‘System’ tab?
