Google just added 17 new devices to the Android Enterprise Recommended Program
Now, in order to be added to the list, a number of minimum specifications need to be met before Google considers a device. For example, security updates need to be provided within a 90-day timeframe, while at least one major Android update needs to be guaranteed. In addition to this, a battery life of at least 8 hours needs to be possible along with a minimum of 2GB of RAM and 32GB of internal storage. Google also has a requirement for the cameras, with a selfie lens of at least 2-megapixels and a rear camera of at least 10-megapixels.
Obviously, the majority of these devices don't have a problem reaching the list of requirements and are often backed a pretty good spec sheet and speedy updates. Sony, for example, has recently sped up its process so much that it took just five days to push out the Android P Beta 2 release for the flagship Xperia XZ2, undeniably paving the way for much faster updates in the future for all Xperia smartphones, not just flagships.
