Google has published its latest breakdown of platform usage, showing the proportion of active devices running each version of the Android OS. The data were collected during a seven-day period ending on February 1, and for a second consecutive month, they show sizeable gains for Lollipop, but only a modest increase for the latest Marshmallow release.
It"s now been four months since Android 6.0 Marshmallow began its rollout, but just 1.2% of devices are now running that version. That"s an increase of 0.5% since last month, when just 0.7% of active devices had Marshmallow installed.
However, that indicates that Marshmallow is rolling out at an even slower rate than Android 5.0 Lollipop, which had made its way to 1.6% of devices three months after its release.

| 2.2 | Froyo | 8 | 0.2% | 0.1% | -0.1% |
| 2.3.3 - 2.3.7 | Gingerbread | 10 | 3.0% | 2.7% | -0.3% |
| 4.0.3 - 4.0.4 | Ice Cream Sandwich | 15 | 2.7% | 2.5% | -0.2% |
| 4.1.x | Jelly Bean | 16 | 9.0% | 8.8% | -0.2% |
| 4.2.x | 17 | 12.2% | 11.7% | -0.5% | |
| 4.3 | 18 | 3.5% | 3.4% | -0.1% | |
| 4.4 | KitKat | 19 | 36.1% | 35.5% | -0.6% |
| 5.0 | Lollipop | 21 | 16.9% | 17.0% | +0.1% |
| 5.1 | 22 | 15.7% | 17.1% | +1.4% | |
| 6.0 | Marshmallow | 23 | 0.7% | 1.2% | +0.5% |
Lollipop saw the biggest growth this month, with versions 5.0 and 5.1 increasing by a combined total of 1.5% to 34.1% of active devices. However, it continues to trail behind the two-and-a-half-year-old Android 4.4 KitKat, which now accounts for 35.5% of devices, following a 0.6% drop compared with last month.
Every other version of the OS saw a decline in active devices since the last set of stats was published, and for the first time in many months, Android 2.2 Froyo saw a drop in usage, falling to just 0.1% of devices.
