After the recent update to Android 4.3, my Nexus 4 has been experiencing many irritating side effects. One of such bugs was loosing the phone signal every now and then. Sometimes the phone will come back online after few seconds. But more often than not, it wont come online and the phone remains without service untill I try to use the phone. In such a case, the only way to force signal search is by enabling Airplane Mode and then disabling it. Eventhough I have put the Airplane Mode Toggle in my PowerToggles home screen widget, enabling the Airplane Mode and then disabling it is a cumbersome thing to do. In order to simplify the process, I wrote a simple Tasker action and put that as a widget in homescreen. The action requires root access and Secure Settings Plugin installed. Using the Tasker App Factory, I have converted the action to a standalone app and you can use it to refresh the signal manually on your Nexus 4 running Android 4.3. I have tested it on my phone and it worked without any issues. You can download the APK file from the link below.
PreRequisites for ths App to Work:
1. Root Access
2. Secure Settings Plugins must be installed
