Does what it says on the tin Gallery app is now finally updated with the pictures I copied to my SD card last month... although the question remains why we need an App to force this to happen rather than Android doing it by itself... even the Refresh option in the Gallery itself didn't work. Anyway, this does exactly what it's meant to do, great little utility app.
Rooted note 3 x note v5.1 When I rooted my device my old photos & some downloaded mp3's/ringtones would not show up on my device. I could view/listen to them through the file manager, but for some reason the device would not repopulate them in the photo gallery/music player. Sdrescan fixed that issue. My Photo gallery is now repopulated with my missing photos, and I can now listen to my missing music/ringtones without going into file manager. Definitely would recommend this app.
Does what it says It's unfortunate that this app is even sometimes necessary. Gallery should always immediately pick up on new media, especially since it takes an extra few seconds for it to load up files anyway.
No longer works Worked great on Samsung Galaxy S5 for months, doesnt work now. Suspect latest S5 update deliberately disabled the app. Crashes on opening; deleting and reloading the app doesn't fix the problem. Was best SD card scanner out there, please fix.
Won't run on Nexus 5 It launches and you get to select agreement, but then crash back to home screen. Then just constant crash after that point. Report has been sent. Nexus 5 with Android 4.4
Works w/ Jelly Bean and HTC Incredible After flashing a new Android operating system, the Jelly Bean ROM, the system app "Gallery" did not see any of my pre-existing photos. I did a Google search for a similar problem and someone recommended SDrescan. It worked. Took about 2 minutes to rescan the whole SD card and all my previous folders and photos were back and now recognized by Gallery.
