The Simple File Manager is an free and open source application for android. This is designed to access files/file folders storage or SD storage.
This is a completely free app has no ads and does not collect any user's personal/device information. This app was amazing it run on offline mode has a simple UI and nice theme color. This app was updated last january 8, 2018 version 3.1.0 and has a total download of 100,000+ from playstore it has good reviews from different user.
My suggestion about this app.:
1. The app doesn't have an Icon where the app user can see the used storage and available storage within device/SD storage in the phone.
Suggestion:
The app should have an Icon of device and SD storage where the app will give information about used and available storage on the phone as you can see the sample below.
Reason:
It is very important to have this Icon of device and SD storage and individual information in term of data used and available space on device storage to make the app more informative for the user.
2. The app doesn't have an cleaner feature.
Suggestion:
The apo should have an cleaner feature in the application so that the app user can manually delete the unnecessary data on device and SD storage of the phone.
Reason:
Inorder the app user can maximize the storage and efficiently use of the device and SD storage on the phone.
This suggestions will make the app more informative ,to maximize the storage and efficient use of device/SD storage on the phone.
