Faceing some problem in recent days which is When I am going to download some thing some time I can't see any notification of download progress bar. On the other hand some time I can see the download notification but I can't see any % or Progress bar which is much frustrating. Although my download is on going. I have a screenshot also. And when I am working with 5/6 tab some time other tabs Site getting load again. My phones RAM management is Ok but Don't know why this is happening. Need help.
