When reprocessing a bunch of stored User Agent strings with 3.6.1 (same with 3.6.2) that where previously processed by 3.6.0, I observe an abnormality: 111 User Agents that were previously tagged "a smartphone browser on Android" ("UC Browser on Android" in even earlier versions of device-dector) are now considered "Generic Bot".

All these user agents contain the Substring Proxy; if I remove this, they are detected as "UC Browser Mini". I wonder if this may be a newly introduced error potentially affecting more rules. However, the other 6 UAs with Proxy in my repository do not change:

* Bots:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:49.0) Gecko/20100101 Firefox/49.0 (FlipboardProxy/1.2; +http://flipboard.com/browserproxy)
Slack-ImgProxy (+https://api.slack.com/robots)
Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via ggpht.com GoogleImageProxy)
* Non-Bots:
Klondike/1.50 (WSP Win32) (Google WAP Proxy/1.0)
BlackBerry7520/4.0.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/5.0.3.3 UP.Link/5.1.2.12 (Google WAP Proxy/1.0)
BlackBerry7520/4.0.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/5.0.3.3 UP.Link/5.1.2.12 (Google WAP Proxy/1.0),gzip(gfe)

I can't judge if the hits from UCWEB are bots or legit but they appear to be from a browser popular in Asia UC Browser.

List of the UAs changed to bot:

I can't judge if the hits from UCWEB are bots or legit but they appear to be from a browser popular in Asia UC Browser.

Those hits are legit. SpeedMode; Proxy is a setting in UC Browser, to load the pages faster, using some sort of caching.
