If you have multiple apps installed for any action, You may want to change default app android uses to perform the action. Suppose, You don’t like android music player that comes pre installed, You want to use Google Play Music by default If any song is played or ear phones are connected etc. You can do that by changing default app.
You can change the default launch app for any action easily in android If you know the default app currently used. You can just go into Settings > Applications > All > select the current default app > Clear Defaults.
There is no way to clear defaults without knowing the app in android. But Default App Manager lets you do this easily. I had to use it couple of times before finding how to use it properly. There are no easy instructions.
How to use Default App Manager to change default apps
1. Download & Install Default App Manager Lite android app from Google Play Store. It is free.
2. Open the app. It has Category Wise, All Defaults tabs. You can look at current default apps under “All Defaults” to clear them.
3. You can set default apps for Audio, Audio Streaming, Browser, Video, Video Streaming etc. Suppose you want to change or set default Audio player on your android phone or tablet.
4. Tap on the Audio category > Set Default > It displays Complete action using popup > Tap checkbox Use by default for this action > Select the Music Player you want to use. It should be set as default. Make sure to tap checkbox Use by default.
If you have any default app for Audio, You can clear it by tapping on the Clear Default > Clear Default again on the app info screen.
You can easily manage all default apps using this app. It works on most android phones including Samsung Galaxy S3, S2, S4, Note 2, Galaxy Grand, Nexus 4, HTC One, Sony Xperia Z, Droid Razr Maxx, Micromax Canvas HD A116 etc.
It also works on android tablets including Nexus 7, Samsung Galaxy Tab 2, Galaxy Note 8, HP Slate 7, fonePad etc.
