Android this week: Nexus S gets 4.0; Galaxy lands on Verizon; Widgets monitor data use

Much of the past few weeks focused on the new Galaxy Nexus, which is no surprise: The hardware pushes some new limits with a screen that rivals a high-definition television. Hardware is only half the story, however, as Android 4.0 addresses many of the user interface issues found in prior Android versions. This week, Google announced that last years Nexus S handset will start to get the new software; the GSM models first over the coming month.Sprint Nexus S is a CDMA model and wont see Android 4.0 in this round of announced updates, but its likely to follow soon.

Those who cant wait for Android 4.0 on a CDMA smartphone can now buy one as Verizons Galaxy Nexus with LTE support launched this week. The handset costs $299 with a two-year contract or $649 without. Various reviews have mostly mirrored my own experience with the unlocked GSM Galaxy Nexus Ive been using for a few weeks, although there are some slight differences.

Due to the LTE radio, it appears that most testers are getting less battery life on Verizons Galaxy Nexus than I am, even though the battery for the CDMA version has a little more capacity. Some reviewers have also noted that signal strength for voice calls isnt optimal; again, something I havent seen on my GSM Galaxy Nexus, although Ive mainly been using VoIP calls over Wi-Fi or a mobile broadband network.

Overall, however, the review community has generally found the Galaxy Nexus as the Android phone to buy now, with a few folks suggesting Motorolas RAZR as a slightly better alternative, even though it doesnt yet have Android 4.0.

With fast LTE or HSPA+ speeds, its easy to hit a bandwidth cap on any smartphone these days. Android 4.0 has some native features that help set bandwidth limits, but most handsets dont yet have this version of software. This week, Onavo added some excellent widgets to its free bandwidth monitoring application for Android phones to help. The three new widgets show real-time and historical mobile broadband use, plus you can view data usage at the individual application level.
