If the devices running the Android OS do not meet the set criteria they are termed as not secure. In such cases, you cannot find Google’s stock apps installed on the device and the devices are termed as Uncertified.

In devices which come under the Uncertified category, there will be an Error “Device is Not Certified by Google” which pops up when you try to launch certain Apps or open Google Play Store or try to Install or Update any Apps on your Android smartphone.
