OnePlus 2 update to OxygenOS 3.0.2, based on Android 6.0.1, about to rollout
OnePlus hopes to have OxygenOS 3.0.2 available to be installed on all OnePlus 2 units as soon as 48 hours from the start of the rollout. Some of the new features include an enhanced version of Doze. This will lengthen battery life on the phone by putting your apps to sleep if the phone is unused for a spell. That means that these apps won't be running in the background, consuming your battery power.
OnePlus says that the update adds system-wide performance improvements, better recognition of fingerprints using the scanner, a new UI for the camera and auto-focus feature, and a built-in update to third party QWERTY provider Swiftkey (to version 6.3.3). Other changes include the removal of MaxxAudio and Tuner, and the addition of Dirac HD Sound to improve the speaker. Apps can be locked in Recents so that they cannot be swiped away, and clear-all removes all of the current apps in Recents with one tap. The Network Operator selection will not change, thus preventing a situation where you accidentally start roaming on a network that you have no business using. This could save you from having to pay accidental roaming charges.
Just a couple of tips. When the notification arrives, before you start installing the new software, make sure that you are connected to a Wi-Fi network. You should also make sure that your battery is at least 50% charged before installing the update.
