Sony beta-testing Android 5.0 Lollipop on the Xperia Z3 and Z3 Compact
With most manufacturers already tipping their Android 5.0 Lollipop update schedule, it is Sony and HTC that will be be crossing into early 2015 for all their handsets that have been promised an update. HTC said "within 90 days" of receiving the source code, which gives them until the beginning of February to figure it out.
cSony's Swedish partnerships have remained from its collaboration with Ericsson, and the company often does testing there, so there's no surprise that the Lollipop rollout is being tried there first.
In any case, if you are interested, you can sign up for the beta-testing from the source link below, or, if you don't want to get involved with Swedish carriers, but own an Xperia handset, you can sleep tighter knowing that Sony is hard at work delivering the Lollipop goods to you.
