In the Christmas and even an older Argos catalogue, there are some tablets that say their OS is “Android Lollipop 6.0”. There is no such thing! It is weird. It may be Android 6.0 or Android 5.0-5.1.1. It is just a mistake. If you are looking for Android Lollipop tablets, do online research about whether the tablet is Android Lollipop or not. If you are looking for Android Marshmallow tablets, do some research on whether the tablet is Marshmallow or not. It is just a mistake. I hope it doesn’t happen again.
