Still wondering where the Android 5.0 upgrade is for your Nexus 5? It may have been held up by a pretty serious Wi-Fi bug that was causing abnormal battery drain, according to a report on the Google issue tracker. Some testers have found that their handsets were dying after just a few hours of use.

Amazon’s built a crazy Bluetooth speaker that wants to be a part of your family. It’s called Echo, and not only will it play your tunes, it has a built-in virtual assistant that will provide all kinds of information when you need it. It’ll even work for you by creating reminders, setting alarms, and more.

Sony knows you’re itching to get your Android 5.0 Lollipop upgrade, so it’s making matter worse by publishing a new video that demonstrates Google’s latest software running on its flagship Xperia Z3. This won’t be the software you get from Sony, however, because it’s pure Lollipop without any third-party tweaks.

Microsoft is now accepting registrations from those who would like access to its beta, which brings the mobile versions of Word, Excel, and Powerpoint to bigger screens.

In addition, the software giant has announced that all Office mobile apps are now free to use.
