Google I/O is coming, and the I/O conference will usually bring a new version of Android. Although everyone has previously speculated that Google will bring Android 5.0 to everyone, more and more evidence proves that this time Google I/O may bring only Android 4.3.

Android 4.3 first surfaced when a user found some mysterious Nexus 4 smartphones and Nexus 7 tablets using Android 4.3 JWR23B system in the access records of Android Police.

According to the server diary of the Android Authority, there are already several devices running Android 4.3, such as Galaxy Nexus, Nexus4，Nexus7、Nexus10、 Huawei U8819 and Fantai Breakout (ADR8995 in the figure).

It can also be seen from the figure below that there are many versions of Android 4.3, ranging from 4.3 to 4.3.1 and 4.3.3. What about 5.0?
