You can settle another launcher like Go Launcher, the Nemus Launcher or Launcher Zeam.
Or, if you want to install another launcher, and deleting settings TwLauncher did not work you can try to make a partial factory reset:
Mark on your phone: * # * # 7780 # * # *
This code is to make a partial reset factory. It deletes the following:
- The settings of your Google account on your phone
- System settings and applications
- Applications downloaded in SD (downloaded, not installed)
No deleted:
- Software and applications you have installed
- The files in the SD.
