"StorageAnalyzer" is a file manager that displays how space is used on your device, simplifying your storage management. 📷 Find duplicate data Duplicate downloads, photos sent through social media or just similar pictures of the same scene: Over time copies can accumulate. The "Deduplicator" tool finds files that are exactly the same or similar and helps you delete extra copies. 👆 Declutter with a swipe Pick a folder and go through files one by one with simple swipes to keep, delete, or skip. The "Swiper" tool lets you review all decisions before anything is deleted, and you can save a session to continue later. 🗜️ Save space without deleting photos Photos can take up a lot of storage, but you don't always want to remove them.

SD Scanner
APK
Rescan storage media like SD cards for changes. SD Scanner uses a method compatible with 4.4 KitKat and 5.0 Lollipop. In Android 4.4 KitKat, the method used by most older programs to rescan a storage medium no longer works. Instead, an interface must be used that only allows one file to be specified at a time. This app works by determining what files/folders might need to be scanned again, and then by calling the correct API on each file/folder. SD Scanner can be used with Tasker by using the "Send Intent" action listed under "System." Use the following settings, leaving the ones I don't list at the default: * Action: android.intent.action.RUN * Package: com.gmail.jerickson314.sdscanner * Class: com.gmail.jerickson314.sdscanner.MainActivity * Target: Activity

SDB Viewer
APK
This app can display the data produced and managed by Song Database if the file is accessible via URL (web address). It cannot be used for anything else, so if you don't use Song Database, this app isn't meant for you! You can view the song lyrics, any available translation and the guitar chords (if available). Translation and chords can be disabled in the settings. The app keeps a local version of the data until it can fetch an update (after a timeout which is three days by default) so you can use it offline as well. If you are the administrator of your Song Database installation and don't want to upload the file containing the songs every time you modify it, you could set up a synchronisation solution like Nextcloud and use the "share link" functionality - the resulting link has to be used in the app. In case you don't want to force all users to enter the link manually: The app can be configured by scanning a QR code. For more information on that, see the homepage.

Open the device with a Torx 6 screwdriver, take out the SDCard, insert the SDCard in an Android phone or tablet, and launch the application. Note that if your device is less than two years old, it's still under warranty, so you'd better contact customer service who will send you a new device if the damage is covered by clauses.

SDRemount
APK
This app tries to restore legacy SD Card write access, which has been removed in android 4.4 and newer. **DISCLAIMER** This is currently a very small and spontaneous project released in the hopes of being useful. While i take my best care to design this application to be stable and never harmful, i cannot guarantee any kind of safety. Use of this application happens on your own risk and discretion, especially since i can only test the application on the few devices that i own. If in major doubt, you might want to test the functionality of the app on your device with an unimportant SD Card first to eliminate any possiblity of data loss. That being said, there's currently nothing destructive going on and misbehavior should entirely be limited to failure of enabling write access. Anything this app might currently do wrong if running on a wrong device should entirely be revertable by uninstalling it and remounting your SD Card. **What is this** With android 4.4, Google decided that it would be time for a new and fancy way to access your internal storage and introduced the Storage Access Framework (SAF). You might have had some contact with it over time. Sadly, with this new feature Google also decided to remove SD Card write access like it used to exist, forcing every app to go through SAF if they want to write something to the SD Card. This required each developer to update their apps. Until this day, some apps still do not support the SAF. This app aims at allowing those apps to write to your SD Card again. It uses a method that should work on android 8.0 and above which involves remounting the SD Card, hence the name. **Requirements:** * A device with an SD Card slot * Root access, since the app remounts some stuff * Android 8.0 or later (but if you are running android 6.0.1, 7.0 or 7.1, it shouldn't hurt to just give it a shot) The approach currently used by this app definitely only applies to devices running android 6 or later. It has successfully been tested with devices running android 8.1, 9 and 10 and unsucsessfully on devices running android 7.1, 6.0.1 and 5.1. With android 10 & 11, storage access became more restricted, forcing all newer apps to go through SAF. It remains to be seen what this does to legacy storage access and this app, and what's to come with even newer android versions. For more information, have a look at the [README](https://gitlab.com/giwiniswut/android-media-rw-remounter/-/blob/master/README.md) and the [Wiki](https://gitlab.com/giwiniswut/android-media-rw-remounter/-/wikis/Home). **How to use it:** * Install * Launch once * Grant permanent root access * Insert or remount some storage * Start writing files to the SD Card **Notes:** * The app must be launched at least once or else the system won't ever run it. This is a security mechanism of the Android platform to protect users from apps they've never launched and maybe never wanted to use or install. * This restriction can be removed by installing the app as a privileged app, i.e. by writing the apk file to `/system/priv-app`. * Upon the first mount with this app installed, i.e. when you actively need to grant root access, it is possible that the app will do nothing. This is because the app will currently be terminated if it has to wait more than a few seconds for root access. Once root access has already been granted and the app is immediately given root access every time it needs it, everything should work as expected. **How do i know if my device is compatible?** TL;DR: Just give it a shot. Ultimately, this app relies on how your specific device vendor chose to implement how your SD Card gets mounted and by which method write access gets removed. With pure android (AOSP), the approach with simple remounting of the SD Card will work from android 8.0 and above, where it uses `sdcardfs` to do the job, a special filesystem originally developed by Samsung. If you have a Samsung device, it's very much possible that it already uses `sdca

SIM Number Setter
APK
SIM Number Setter is a small Xposed module that invokes normally unused Android System code to set the "subscriber number" on the device's SIM card. This is the number displayed in the system settings, and used in apps such as Google Messages, as well as being available to third party apps with sufficient permissions.The number is not always set by carriers (leaving "Unknown"), or can be lost or invalid after porting a number to a different SIM. This small app allows you to fix it, permanently, using a rooted device with Xposed.If you don't have a rooted device, or don't want to root your main device, you may wish to consider rooting an old device, and temporarily putting your SIM into that device, using this app, and then putting it back in your main device - the fixed number will travel with it.Important Notice: Changing the SIM number is semi-permanent: the number change will survive reboots, uninstalling this app, even switching the SIM to a different device, but can be changed again at any time using this app.
