The latest news of the time is that Salesforce has recently announced that it would upkeep limited Galaxy and Nexus handsets from fragmentation. The strategy was set in order to avoid wasting time as well as money in testing the applications for hundreds of Android devices.
In this context, Salesforce has explained that due to the vast array of available Android devices (various versions), the firm would be targeting to a select number of Android devices and open up the applications for them only.
Talking in terms of Nexus handsets, it would support Google Nexus 5X and the Google Nexus 6P only.
