日前，谷歌公布了针对Android Market用户的一项调查追踪结果，发现在过去两周中，运行旧版的Android 1.5操作系统手机用户占6.3%，Android 1.6的手机用户占10.6%，Android 2.1用户占39.6%，Android 2.2用户占43.3%。

调查数据表明，大多数Android用户并不能经常更新手机操作系统，除非用户采用越狱手段，否则手机固件的选择权仍掌握在运营商手里。

Change in Android OS usage

43% of active Android Market users are on OS 2.2

Calculated by tracking people accessing the Android Market over the past two weeks, Google has broken down some figures in terms of the usage share of the various flavours of its mobile OS.

Old school Android 1.5 was on 6.3 percent of devices, Android 1.6 was on 10.6 percent, Android 2.1 on 39.6 percent and Android 2.2 on 43.3 percent.

Most Android users can’t actively update their devices, as unless you’re jailbroken your phone, operators control what firmware gets pushed out.

More interesting perhaps, is the following graphic showing how the usage breakdown has changed over the past six months of 2010.（source:pocketgamer）
