The "Devices" Report, probably based on data from DeviceAtlas.comis not really useful, since it contains the device identifier in the Name string and thus does not group equivalent devices. There are e.g. dozens (hundreds?) of "Galaxy S7" devices which are all the same, but have slightly differing names. Utilisation of more inclusive DeviceAtlas tables would be beneficial here. Today, we don't know our most common Android devices -- especially since the Devices Report can not be classified.
For example: https://sc5.omniture.com/x/5_1uf35 lists all "Galaxy S7" devices. However, - Orange Galaxy S7 (SM-G930F) - Verizon Galaxy S7 (SM-G930V) - T-Mobile Galaxy S7 (SM-G930T) and dozens of others are all listed as individual devices. This is not at all helpful when trying to understand common hardware in your userbase.
It would already be helpful if "Device Name" would be available in two variable, e.g. "Samsung Galaxy S7" and "SM-G930". Even better if these variables would be classifieable.
