Uc browser mini is a very useless app. You can not download gigabyte files from this app. The speed of this app is also low. I have to download a gigabyte file of windows 7, I thought that I download it from uc browser mini. When I tried to downloading the iso file of windows 7, it was not downloading. Iso file size of windows 7 was 3.9 gigabyte. Some pages are not open in uc browser mini. That is why did this app for only 3 months.
