In my s7 device I have a serious problem

[Awesomenessa]

I can't download from some applications but I can upload things and in some other applications I can't upload.
For instance I use telegram social application I can update my status download things but when I try to upload anything it stucks at loading. In my second application named bazaar I can see applications details, icons but I can't download

Welcome to Android Central! Does this happen on both wi-fi and mobile data?

Ok, try going the App Manager, tap Menu>Show System, and select Download Manager. Then tap Storage, then Clear Cache/Clear Data. Now try again.
