Whilst tinkering with my Samsung SG2 in a vain effort to get my calendars sync’ing properly via ActiveSync I some how managed to break the TouchWiz Launcher (I believe clearing the calendar application data cache was to blame – may have been a coincidence, but I doubt it).
This caused a Unfortunately, TwLauncher has stopped error to be displayed after a long pause with a blank screen when trying to do pretty much anything. Turning my precious smartphone into an infuriating lump of screen and plastic.
There are various fixes to be found on the internet, with varying levels of severity, including…
- Installing an alternative launcher from the app store (aka Google Marketplace, or Play Store, or whatever its called today)
- Factory default reset
…none of which I fancied, thankfully there was a simpler solution for my issue.
Firstly, what does TwLauncher do? Its the application name for Samsung’s TouchWiz interface, which provides home screen customisation, gesture controls and so on. Its responsible for much of the look and feel that you experience with a Samsung Android phone (yes, TouchWiz is also present in other Samsung devices that have touchscreen interfaces other than Android). This means that if TouchWiz is knackered, then the look and feel (and usability) of your device is also knackered.
Be aware that this will reset any home and application screen customisation you may have done. It may take a few attempts to get into Settings, be patient and keep trying
- Go to Settings, and to Applications
- Go to the All tab
- Scroll down the list until you find TwLauncher
- Go into TwLauncher and press Clear data
If the repetitive error is thwarting your attempts to fix, then you might need to install a new Launcher. Browse to Google Play Store and login. Then select a new (free) launcher and send it to your device.
