Within few days, the Android 4.1 Jelly Bean update for Motorola Droid 4 will begin pushing to devices. The update only awaits for Verizon's approval to the Android 4.1 Jelly Bean before the release can start.
Motorola appeared to have made a soak test of Jelly Bean update for the Motorola Droid 4, and it confirms that the update version would be 4.1 Jelly Bean. It turns out as well that Verizon finally approved the update and posted the details for owners to see on its Droid 4 support page.
As usual, the update may go in phases once it rolls out which means owners will get their hands on it at different times.
On the other side of the Android, an AOKP Build 5 ROM is available for Motorola Droid 4, and this one carries the 4.2.2 Jelly Bean version. AOKP feature lots of customisation and tweaking of the ROM so that users can maximise the control over Droid 4.
