I used uc browser-fast download since 4 years.now I knew that this is not safe and secure for our personal data and information.also google banned uc browser from their play store.
The name uc browser-fast download is trustful for downloading only small files.when we downloading large files like 1 gb or more, then it is download with very less speed and also started to pause automatically.
Ad block is a good thing of uc browser.but not trusful for personal info.so I recommended guys to not use uc browser if u want to safe and secure on online.
