Fragmentation? What fragmentation? Netflix’s Android app is being used on close to 1000 different Android devices each and every day, complete with multiple OS versions and custom ROMs. But for its daily testing, the company relies on a surprisingly small array of Android handsets and tablets.


Remember all those stories about Android device fragmentation, and how it’s been keeping companies like Netflix from rolling out their apps across the entire Android ecosystem? Apparently, it’s not all that bad: Netflix is now seeing its service used on close to 1000 different Android devices each and every day, according to a post published on the Netflix Tech Blog Wednesday afternoon.

So what does it take to test your app for this multitude of devices? Apparently, not that much:

We have taken stock of all the devices we have in house and classified them based on their specs. We figured out the optimal combination of devices to give us maximum coverage. We are able to reduce our daily smoke automation devices to around 10 phones and 4 tablets and keep the rest for the longer release-wide test cycles.

A subset of those ten devices that are being used for daily testing is depicted on the image below:

It’s worth noting that Netflix isn’t apparently just conducting those tests with devices scattered around on a hardwood floor, but that it is also including custom ROMs like CyanogenMod 7 and CyanogenMod 9 in its tests.

    It would appear they don’t test on the Xoom at all as the Netflix is by far the worst performing app I’ve ever used on the device.

  2. good for netflix! now if only they had 1000 subscribers left it would be even better.

  3. 10 phones and 4 tablets…yeah, that’s totally feasable for a small developer.
