I recently notice that approximately 17 % of users with ios device have browser with strange user agent. This user agent like the Safari user agent but with slight modification: it does not contain "Safari/XXXX" string.
Example:
normal user agent of Safari:
Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5355d Safari/8536.25
user agent of browser that i talk:
Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5355d
Can somebody explain me, how it can be? Which browser have this strange user agent?
The shorter user agent comes when an ipad enters "web app" mode. This means that a phone is parsing the html only using webkit, in full screen mode, not within a safari browser window. Thus only the information about CPU version, webkit version, etc is sent along.

ipad user agent changes during use?

I'm parsing s3 logs to identify requests made from iMessage previews (on Mac OS Sierra & iOS 10).
There are few common types of UA strings, but I can't tell which are from the browser vs. imessage. I'm hoping it's a unique UA from Safari:
`AppleCoreMedia/1.0.0.14B100 (iPhone; U; CPU OS 10_1_1 like Mac OS X; en_us)
^ Gotta be iOS Safari, right?
2.MobileSMS/1.0 CFNetwork/808.1.4 Darwin/16.1.0`
^ I think MobileSMS means imessage (hopefully)
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.1.32 (KHTML, like Gecko) Mobile/14B100 Twitter for iPhone
^ Twitter via webkit webview?
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/54.0.2840.91 Mobile/14B100 Safari/602.1
^ more iOS Chrome (i see you CriOS)
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0 Mobile/14B100 Safari/602.1
^ more iOS Chrome?
Twitter/5002568 CFNetwork/760.6.3 Darwin/15.6.0 (x86_64)
^ Twitter
I've just faced the same issue while trying to re-route the iMessage crawler to a non-angular page which will generate the correct meta tags for it and found this question in the process. Figured I'd write an answer since I've now found it. Apple's documentation says nothing but mention the ...(Applebot/x.x) User-Agent which is not the correct one. I've found nothing on the internet so I logged traffic to just one file on a public server and shared the link via iMessage. In the log file I received:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/601.2.4 (KHTML, like Gecko) Version/9.0.1 Safari/601.2.4 facebookexternalhit/1.1 Facebot Twitterbot/1.0
When I've modified my RegEx to fit this User-Agent, the iMessage crawler was finally re-routed to the correct location.
So there it is, it's probably subject to change without notice since it does not exist in any official Apple documentation as far as I can tell but I hope this still helps someone :)
Use this regex to identify requests from IMsg crawlers.
(Twitterbot(.*)facebookexternalhit)|(facebookexternalhit(.*)Twitterbot)
I have tested it and it works perfectly.
We're doing some server side device detection and need to drive ipad mini users to one page and ipad users to another.
Is there any thing that differentiates the two user agents?
iPad
Mozilla/5.0 (iPad; CPU OS 7_0_3 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11B511 Safari/9537.53`
Mini
Mozilla/5.0 (iPad; CPU OS 7_0_4 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11B554a Safari/9537.53
The only thing I see is the Mobile/11B511 and Mobile/11B554a, but is that a persistent value that we can work off?
Trying to do a device detection these days is hard and not reliable. I would recommend you instead of device detection to do a detection based on browser capabilities like I described it here.
Using this approach you are interested only if the browser supports a feature and you don't care about the device name/vendor.
I have a web page that when viewed from an iOS device displays slightly different content. To detect the device in question the site looks for iPad;, iPod;, or iPhone; in the user agent string.
This works perfectly on Safari on all iOS devices. Testing with Chrome for iOS it works on iPhone and iPad 1, but not iPad 3. The web site is getting the following (unexpected) user-agent string:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.53.11 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10
This seems to be related to the "request desktop site" option in the chrome menu (what would be the wrench icon in desktop chrome). For my site it's disabled and seems to be locked to the desktop rather than mobile site. For other sites, it's enabled and results in a different user-agent string being sent when selected. eg: try http://ifconfig.me/all
So my questions are:
what criteria does Chrome use to decide whether to enable this option
given that Chrome has forced this site to the desktop site, how do I render iOS specific content (in my case a link using a protocol that is handled by my app)
If you'd like to test this yourself, there's a page here that simply reflects the user-agent string.

The browser will switch between using the two User Agent strings based on whether you are acting as a mobile browser of masquerading as the desktop browser.
User Agent:
Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; en-gb)
AppleWebKit/534.46.0 (KHTML, like Gecko)
CriOS/19.0.1084.60 Mobile/9B206 Safari/7534.48.3
User Agent after "Request desktop version":
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3)
AppleWebKit/534.53.11 (KHTML, like Gecko)
Version/5.1.3 Safari/534.53.10
This is only a hint to the web server about who the client is. The browser should render the received web content independently of the User Agent.
I'm trying to view a users tweets from my app but twitter responses with a webpage saying:
Sorry that page is not supported on mobile at this time
However if i load the same URL with mobile safari i get a nice webpage with all the tweets.
I'm using this URL: http://mobile.twitter.com/SOME_USERNAME/tweets
You can reproduce the error message by visiting the url in safari. If you use safari as developer and you set the user agent to iPhone you'll get the right page.
It seems the webview is sending different headers as User Agent:
Mozilla/5.0 (iPhone Simulator; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9B176
vs
Mozilla/5.0 (iPhone Simulator; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
Is there anything i could do about this problem?
Apperently it does work when i remove the /tweets part of the URL.
This is not really the answer to my question but it is the best option as long as nobody comes up with a better answer i'll accept this answer.
Is it possible to get the model information of an iPhone hitting a web page? I've looked at the User Agent, but it doesn't seem to have this information encoded within it. Essentially, I want to do this but from a browser.
They do have different user agent strings. iPhone 4 is
Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7
