Devices statistics

Is there a way to know the statistics about the device?

I would like to know my newsletter opening percentage via a smartphone.

So, although this is now available, it does not seem to be working correctly.

I know my audience quite well from GA stats and UTM captured campaign stats, favouring 63%+ mobile devices. However, the device and operating system stats I see here in MW shows 95% Windows / 97% Desktop / 80% Firefox Browser. That's just completely impossible. Yet, it's consistent through all campaigns. It can't be me, because I don't use Firefox.

Am I missing something? Does anyone else have that same problem?

@nadworks - we extract that info from the user agent string we get from them while opening and clicking campaigns.
It also contains info from proxies which open the emails in behalf of users, or spam filters which do that, so this might be one reason for why the data is off. Remember that you can add ip addresses and ip ranges to block opens and clicks tracking from certain sources. This will give you more accurate data.

This seems to be the Google image proxy issue:
This is my user agent of 94% of opens:
Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via GoogleImageProxy)

Any way the device stats can be outmanoeuvring Google's cached image? This issue has been around for a while and is not affecting stats of other email platforms as far as I can see. So they must be capturing this insight differently.

Here's more about the known issue:

Hi @twisted1919 and team - do you have any plans to improve the accuracy of device and OS statistics, which are so very clearly still screwed up?
I'm increasingly asked by clients about their subscribers' behaviour and preference in that area, and it would help me immensely making a case for certain design and build decisions if I was equipped with actual audience's statistics.
I feel the current method is somehow dated and not taking ESP specific methods into account. I.e. the first gmail user's open action will serve all other gmail users that very same cached image. In a nutshell, that first useragent data is subsequently used for ALL other users on gmail, regardless how they open their emails.
