Ans: Yes! There are few changes in the UC browser, the main change is that you have new features to call or video chat with your friends.
You can also send an SMS or email to anyone with the help of this app which you cant do in the official version of UC browser.
Apart from these, the developer mode for checking online visitors will be removed so you need not worry about such things there will be no ads as well on this version of the UC browser.
