So which Motorola phones are getting Jelly Bean?28
Motorola DROID RAZR is expected to be updated to Android 4.1 some time this quarter, along with the Motorola DROID RAZR MAXX. Other phones like the Motorola DROID BIONIC and the Motorola DROID 4 will receive the update, but no date is mentioned. Also waiting for the update is the Motorola PHOTON Q 4G LTE (on Sprint) and the Motorola XOOM LTE. A decision has yet to be made on whether or not the Motorola DROID XYBOARD 10.2 and Motorola DROID XYBOARD 10.1 tablets will receive the update.
The new set-up allows you to leave your email address with Motorola to get notified when your device is about to receive a new update, and if you access the page from your phone, Motorola will let you know if your handset is running the most up-to-date build of the OS. Motorola has not been known as the quickest to update its models, but that might be changing. The manufacturer was quick to update its latest flagship devices, the Motorola DROID RAZR HD and the Motorola DROID RAZR MAXX HD, with Android 4.1. It seems that with the special relationship Motorola has with Google, future updates should continue to be quick.
