I use regular opera mini, there is a lot of problem in it. It is a very bad browser. uc browser cannot able to access for long time on large web pages.Sometimes it has slow browsing network which can not so fast without good networking data.4g net to give it a speed of 2g net. Many websites can not be opened from the browser, but it can not be done anytime, but they are again open from Chrome or Firefox. Main problem in using uc browser is that is not secure for web browsing it does not have any privacy system to secure your search.I suggest using Chrome or Firefox is very good to use Opera mini browser.
