Android smartphone users are eagerly waiting for the latest OS upgrade, Android 6.0 Marshmallow. Several original equipment manufacturers (OEMs) have already started rolling out the new software to their devices, and Xiaomi is expected to join the bandwagon real soon.

Xiaomi's MIUI operation manager confirmed that Android 6.0 Marshmallow for select devices has reached its final testing phase and the update process will begin soon, GizmoChina reported on Thursday.

In the report, the Chinese publication also revealed the devices to first receive Android M will be Xiaomi Mi 3, Mi 4 and Mi Note. RanGer wind, the Weibo account name of the MIUI operation, also shared a screenshot of the latest update with MIUI 7 on it, which shows the MIUI 5.12.24 update based on Android 6.0 Marshmallow weighs 518MB. Be sure to connect to a Wi-Fi while downloading the new software, 

Even though the official Android 6.0 Marshmallow changelog is already in the open, there is nothing much to go by in terms of Xiaomi-specific changes in the new update. Since the update is currently in its beta stage, users will have to wait until the new OS passes developers and comes as a stable OTA.

It is also unclear exactly when Xiaomi will begin rolling out Android 6.0 Marshmallow for the aforementioned devices, and if the international users will receive the new OS alongside the China version, which is unlikely.

It's worth noting that novice users stay clear of the beta version when released, which is meant for experimental purposes and mainly used by developers. It's best to wait for a stable OTA update, which, according to GizmoChina, is still months away.

Since Xiaomi is upgrading the base OS and not its MIUI software, the testing should come to a close soon. With this, the Chinese smartphone-making company will finally address the long-overdue concern of users who were disappointed to see most devices stuck on Android 4.4 KitKat while using the MIUI 7 ROM, India Today noted.
