What does QQ mean by saying that it is Android?

At present, the dynamic "slave" (tail) function of QQ space can be divided into the following situations:

1. Only five mobile phones (iPhone5, Xiaomi 2, Samsung I9300 GALAXY SIII, Samsung N7 102 GALAXY Note II, Samsung i9300 Galaxy SIV) will display "From the mobile phone model" (for example, from iPhone 5);

2. Other models of Android phones or iPhone phones will only display "from Android" or "from iPhone" in the dynamic released through the QQ space software version of the mobile phone;

3, Windows Phone and mobile QQ space web version, 3G version, touch screen version) release dynamics do not support displaying the tail;

4. "WeChat, Friends Network, Tencent Weibo, QQ Signature, Mobile QQ" and other dynamics will no longer display the tail (Note: some third-party websites will still display the tail).

So it means it's a call from andorid system. Tell me about it.
