Presently, searching for UC Browser on Google Play brings UC Browser Mini, which is the lightweight mobile browser by UCWeb. The official UCWeb site has provided a link to sideload the UC Browser app through its APK file, though.
“We were informed by Google Play about temporary removal of UC Browser from the Play Store for 7 days, beginning 13 Nov 2017, under the reason that a certain setting of UC Browser is not in line with Google’s policy. We have conducted an urgent internal investigation and fixed the problem. The new version has been uploaded on Google Play’s Developer Console and is awaiting evaluation. We will actively cooperate with Google Play for any concern caused by this unintentional error. In the meantime, users can still download UC Browser Mini from the Play Store, an alternative version of UC Browser. We thank Google Play for their understanding and support extended to us. UC Browser new product package will be back on Google Play next week and, in the interim, users and partners can download the product from our website http://www.ucweb.com.”
