Call Forwarding Icon Keeps Appearing Android Galaxy Nexus

Removing the Call Forwarding Notification Icon on a Samsung Galaxy Nexus

Call Forwarding Icon Keeps Appearing AndroidAfter a recent trip abroad the Samsung Galaxy Nexus that was being used was turned off from Aeroplane mode. Up popped a notification to say that call forwarding was active, even though it had never been enabled. (The icon is a telephone handset with a arrow pointing outwards.)  Despite checking that the call forwarding option Always forward was indeed set to Disabled, and clearing notifications the icon (and notification) refused to go away. This particular phone is on the Three network in the UK. It was a simple solution in the end to fix the call forwarding icon keeps appearing android issue. It was to just dial ##20#. If you want the the full story read on.

Note, to access the call forwarding settings go to the dial keypad (via the handset icon) access the menu and select Settings then Call forwarding. The Forward when busyForward when unanswered and Forward when unreachable settings are configured for the 3 network’s voice mail number, 07782333123 (i.e. +447782333123). From the mobile phone voice mail is accessed by dialing 123. The phone appeared to be configured correctly but the call forwarding notification would not budge.

This Samsung Galaxy Nexus had failed to upgrade to Android 4.3 with the Over The Air (OTA) update prior to the trip. This needed to be done manually and would reset the phone. Which was planned for after the trip abroad. Following the Return to Stock for all Galaxy Nexus Phones guide on the xdadevelopers forum the Android 4.3 update was completed. (When doing manual system updates remember to back up everything as it will all be lost, music, data, texts, everything). The phone rebooted after the upgrade and pop, the call forwarding notification appeared. This meant it was a network or SIM card problem and not a phone issue.

What if the Call Forwarding Icon Keeps Appearing Android Samsung Galaxy Nexus?

Well a web search soon found the solution. It is a Three network issue. To clear the notification when the call forwarding icon keeps appearing Android Galaxy Nexus just dial ##20# and press the handset, as if making a call. A message should appear briefly to say erasure was successful or similar. Very simple solution in the end. If you get this issue let’s hope this solution works for you.

Nexus 7 ADB Driver from ASUS Required When Debugging Your App

Why ADB is not Listing The Nexus 7 Tablet

Eclipse Run Android AppWhen using Windows to develop Applications (Apps) for the Nexus 7 using the Eclipse IDE (or Android Studio), the tablet may not seen in the Android Device Chooser dialog when the Run button is pressed. This is because the Android Debug Bridge (ADB), which runs in the background as adb.exe, cannot communicate with the Nexus device. This short article runs through several possible causes, starting with the most likely reason.

The ASUS Nexus 7 ADB Driver is Required

Use the Asus Nexus 7 ADB Driver when Debugging AppsHaving installed the Android SDK the default Google USB driver is not used for Nexus 7 debugging. Instead the ASUS Nexus 7 ADB driver for Windows must be installed. If you open Windows Device Manager, via Control Panel and System (or in Windows 8.1 type device manager at the Start screen), Nexus 7 will be listed with a small yellow exclamation mark. This indicates a driver is not correctly installed.

The SDK Manager program, installed with the Android SDK, has the option to install the Google USB Driver, normally done by default. (If not run SDK Manager.exe and when it has refreshed the list of packages scroll to the bottom. In the Extras folder select Google USB Driver and click the Install Packages button.) The Nexus 7 ADB Driver is not installed via SDK Manager. It must be installed separately.

Asus Nexus 7 Windows Driver Installation Instructions

To install the Nexus 7 ADB driver for Windows first download the driver from the Asus support pages at http://www.asus.com/Tablets_Mobile/Nexus_7/#support_Download_8. Click the USB link, then Global next to Download from and save the zip file to your computer. The Nexus 7 ADB Driver file is called usb_driver_r06_windows.zip (r06 may have increased if the driver has been updated since this post). Extract (copy) the contents of this zip file to a new empty folder on your PC. Open the Nexus 7 device properties in Window’s Device Manager (double-click) and select the Update Driver button. Browse and select the folder with the extracted driver files. The driver will be installed and the Nexus 7 listing in Device Manager will change to Android Phone and Android Composite ADB Interface. The Nexus 7 should now be available to select when an Application is executed in Eclipse.

Checking Other Nexus 7 Developer Settings

The Nexus 7 USB Debugging options are available from the notifications area when you plug the tablet into the computer. Pull down from the left side of the notification area and select the USB debugging entry. If USB debugging is not enabled it will need to be turned on in Settings. Access settings by pulling down on the right notification area and selecting settings (or go into all the installed Apps from the home screen and find Settings). Scroll to the bottom and select Developer options (if not visible see next paragraph), then check USB debugging.

Enabling Nexus 7 Developer Options in Settings

Developer options may not be visible under settings. To make it visible select the About Tablet entry in Settings. In the About tablet screen find the Build number at the bottom of the list. Tap the build number several times (about 7). After about three taps a message appears and counts down, when it reaches zero the Developer options will have been enabled, press the back key to see the new option in Settings.

Switch Nexus 7 USB Connection Modes

Some developers have needed to switch the USB computer connection mode from Mobile device (MTP) to Camera (PTP) to get the Nexus 7 detected by ADB. In Settings select the Storage option. Select the menu at the right hand of the notification area, then select USB computer connection.  Change the connection option.
