Many bugs in v1.3.1

[rzdys]

Sir,
There are many bugs as compared to the previous versions
In latest v1.3.1 these are the following bugs

1. Retains old download locations and not saving changes in the download location.
2. The back button always closes the app. Problem arises when you are viewing more info page of a downloading file and you press back instead of going to the main page of downloading it closes the app which is very irritating.
   3)I think there is something wrong with file allocation system because there are many error due to this. Also, many duplicates of same file of different sizes formes which causes error and takes unnecessary space.
3. I don't know but this v1.3.1 is slower and buggy than previous versions.
4. There are many more bugs.....

Besides this, I appreciate your project and have already star marked your project.
Pls resolve these issues in the upcoming releases.
