Oppo has released Android Marshmallow update for the Oppo R9, R9 Plus, and F1s smartphones. However, the update is available only for customers based in Australia. If you are located in Australia and work with any one of the smartphones, you can expect a message notification about the update, which will enable you to upgrade from old Android Lollipop to Android Marshmallow.
If you install the update, your handset will be reloaded with a new version of the ColorOS. Moreover, you will be able to experience dual-sim functionality with 4G and 3G compatibility if you work with the OPPO R9 Plus and R9 after the Android Marshmallow update.
The official support page of Oppo Australia has provided relevant links to the update file for all the three Oppo handsets. You need to download the file relevant to your device via Wi-Fi and proceed with the installation. You should make use of 4G connectivity only if you have unlimited bandwidth more than 2GB.
Oppo has avoided the OTA route and moved to direct download option. You just need to download the file from within your Oppo handset and proceed with the installation.
The main point to note is that you should backup all the data from your Oppo smartphone because your existing data will be erased during the upgrade process. Oppo has specifically mentioned that the data will be wiped out. Hence, you need to be serious and copy all your images, videos and other data from your existing Oppo handset.
Meanwhile, the OPPO support page has started that you should charge the battery up to 40 percent before starting the download process. However, we would suggest you charge the phone to 100 percent to avoid interruption. You should also free up nearly 1.5GB of valuable storage space before initiating the installation process.
Oppo has warned that since the size of the upgrade file is large, the whole download and subsequent installation process will take some time to complete. Moreover, you should not switch off your OPPO phone or perform other operations such as removal of the battery during the installation process.
After the installation of the Android Marshmallow update, your phone will perform a reboot and displays the OPPO logo for over five minutes. Hence, you should not have to worry about it since it is normal.
