It's no secret that Bluetooth has been a problem child for Android, plagued with poor audio quality and connectivity issues. I've already covered a handful of common problems in a previous post, but another issue has been emerging in the last few months that threatens to virtually kill all Bluetooth operation on a device in the right conditions. The culprit is a nasty little oversight in the Bluetooth Low-Energy code added with Android 4.3 Jelly Bean.
Do you use a Sony Xperia Z? Did you buy it from T-Mobile? Then check that Settings menu - according to this T-Mo support page, you're getting a taste of Jelly Bean 4.3 starting today. Of course these things tend to go out in waves, so those without patience can follow the links on T-Mobile's site and manually download and flash the new software (10.4.C.0.797) using the Sony PC Companion software.
Just yesterday HTC committed to two full years of updates after release for new phones, but it looks like the company isn't keeping the updates to recent hardware. Last night Martin Fichter, one of HTC's US vice presidents, posted a link for a ROM Update Utility file ("RUU") for Sprint's HTC EVO 4G LTE to Twitter. The RUU updates the phone to Android 4.3 and Sense 5. If you've got an EVO 4G LTE phone and a Windows computer, you can flash it right now.
Sony bumped the Xperia Z1 and Z Ultra to Android 4.3 in December, but a new software build is starting to make its way to users starting today. This one has build number 14.2.A.1.136, but it's still Android 4.3 – Sony is just doing a little housekeeping.

Last month the upgraded Butterfly S got the last version of Jelly Bean and the shiny new Sense 5.5 UI, and it looks like HTC's software team has worked their way to the original Butterfly model. Noted HTC leaker @LlabTooFer posted the over-the-air update screen this morning, and at least one blog showed the same software update going out in Malaysia yesterday. According to a Twitter reply, the Taiwanese variant is being updated as well.
Dell began sending out Android 4.3 updates to it's budget Atom-based Android tablets late last year, but it's been a super-slow rollout. Well, now it's picking up steam. The OTA should be hitting both tablets soon, if not already.
While the Nexus elite have since moved on to KitKat, there are still a lot of devices just getting by with some flavor of Jelly Bean. At least Sony is keeping its promise of updating devices to the latest version of that sweet-themed platform. Android 4.3 is beginning to make its way to the Xperia Z, Xperia ZL, Xperia ZR, And Xperia Tablet Z.
