A few weeks ago T-Mobile announced an update to Android 4.1.2 Jelly Bean P76920d for the LG Optimus L9, much to the delight of the handset’s owners everywhere. Unfortunately, it looks like the T-Mobile LG Optimus L9 owners will have to go back to waiting for JB once again, as T-Mobile and LG have put things on hold due to some issues with the update. The following statement can be found in a support document which was released yesterday from the carrier:
Some users who had installed this update complained about apps frequently crashing, battery draining and having difficulties in receiving calls. There’s no word yet on when the update process might get going once again. Obviously we’ll pass along more details as soon as we get them.
