Sony currently run Android 4.0.4 on the Xperia Miro, continuing the trend of keeping the software identical to the more expensive models. As we mentioned before the OS is heavily skinned by Sony though most of the changes are cosmetic when compared to stock Android.
We have access to 2GB of "internal storage" with 750MB of space partitioned off specifically for apps. We can of course expand this with a microSD card, up to 32GB and Update Centre assists us in managing updates to the device.
Overall the camera is responsive and the 5MP sensor gives decent images which are a step above most low end phones. We also get a nice selection of options which allow us to tweak the images to our situation and basic video recording is available too.
In terms of the overall feel of the OS movement around the OS on a freshly unboxed handset is responsive with minimal lag. Applications launch in a decent amount of time and all of the functionality we would expect of Android can be found here. Finally we have battery life which more than acceptable for a lower cost handset, standby use shows minimal drain and we were able to make it through a day of reasonably heavy use with no issues.
