After a bit of a lull between what were a consistent run of updates, Oppo finally let its newest build of ColorOS out of the starting gates.
ColorOS 2.1.5i is being released as a stable, not beta, build, and the development team at Oppo stated this would be the last ColorOS update for the venerable Find 7.
What does that mean? The team is shifting its focus on AOSP development. Oppo has been making AOSP builds for the Find 7 side-by-side with ColorOS for a while now, and with that, we can glean that we will begin seeing a more stock looking UI for Oppo devices with ColorOS features. If that sounds like a somewhat familiar set up, like Cyanogen 12, or OxygenOS, you would not be alone.
Right now, the AOSP (v1.1 Beta) build for the Find 7 is still built on Android 5 Lollipop. Version 2.0 is in private testing, and a Marshmallow build should be available early next year.
As for ColorOS 2.1.5i (also built on Android 5 Lollipop), it consists of mostly bug fixes and a couple of updates. New to ColorOS is an added support for Smart Lock in the settings. Also, you can disable Google apps when editing the homescreen. Finally, a long-vexing issue of microSD card problems has been fixed. Other tweaks include color correction for RAW photos, fixing notifications with WhatsApp while running in the background, and a patch to resolve the stagefright leak is among the notable changes.
All-in-all, a light update, but a notable one. We are looking forward to seeing how Oppo will incorporate its considerable feature list from ColorOS into the Android Open-Source Project in the future.
You can download ColorOS 2.1.5i and update directly off your Find 7, or wait for the OTA package to release on Monday.
