Top 25 Android Devices to Test On In 2015

Android Device Fragmentation

OpenSignal have published their Android fragmentation report for 2015 and the results are really interesting! Samsung is leading manufacturer – so much so that in Top 10 there is only one non-Samsung device and even in Top 25 there are only three other manufacturers represented: Asus, LG and Motorola. You have to go all the way to around Top 30-35 to see an HTC or a Sony. One of the biggest surprises is that how well the new Asian brands such as Oneplus, Oppo, Lenovo and ZTE are represented in Top 50. Clearly they are building momentum that can possibly make a dent on Samsung’s market domination.

From the top 10 it is interesting to see that while 9 out 10 devices are of the same brand there is significant Android fragmentation on the hardware platforms, software and device segments that need all to be taken into account when testing your app against these devices. For instance you have Galaxy S3 and Galaxy Note 2 from 2012 that haven’t received Android OS updates very recently and you have low end devices like Galaxy Core 2 and Galaxy Grand Prime as well powerful top end devices such as LG G3. Also resolution wise the lowest resolution on Top10 is very moderate 480 x 800 of Samsung Galaxy Core 2 and Samsung Galaxy S Duos while the highest resolution is staggering 1440 x 2560 of LG G3 and there are numerous other resolutions represented in Top10 alone.

When you look at Top 25 there already are more manufacturers and more variety on the device types as well.

Again, there is a good variety of top end and low end devices with Asus Zenfone 5 and Motorola Moto G bringing variety to the mix.

Conclusion and Recommendation

Open Signal’s Android fragmentation report for 2015 shows clearly that the days when you could get decent test coverage on 10-20 or even 30-40 individual devices are long gone. Even if you cover 50 device models, you will cover roughly 25% of the market and in order to cover 50% of the market, you would need to test on roughly 150 unique devices. This is very different situation from for instance a year ago, when you were able to cover 50% of the global market with about 60 devices and were able to cover about 20% global market coverage with 12 just devices.
