Xperia Z3 AOSP Lollipop ROM with working calls appears, although not quite ready for daily use

Early AOSP Lollipop source code was made available for Xperia smartphones last week and has already been put to some use. A work in process Lollipop build for the Xperia Z3 has been published by developer krabappel2548, although there are still some big issues left to sort out.

The ROM improves on the lack of modem support offered by Sony’s initial source code release. SMS is working and calls have been implemented to some extent, although unfortunately the microphone doesn’t appear to be working 100 percent of the time yet, so there is clearly still work to be done.

The build is still in the very early stages, so a number of features required for the ROM to be truely usable still need to be implemented. Camera, GPS, mobile data and the microphone aren’t functional just yet, but WiFi, Bluetooth, vibrations, sounds, etc are already up and running.

This ROM is only really aimed at showing off what Lollipop looks and feels like running on the Z3 and for the most part it is smooth and stable. Although it certainly isn’t recommended for anyone looking for a daily driver. The developer is planning to work out all the kinks and bring this up to a fully functioning ROM for the Xperia Z3, but that is likely to take a considerable amount of time. Hopefully the development community will get behind this early build.

Despite the bugs, this is a promising sign of things to come for Xperia Z3 owners and the the custom ROM community. If you’re the tinkering and ROM flashing type, you can find the download and instructions in the source link below.
