The only reason I am still using an iPhone is due to the fact that most Android phones did not allow control of per-app access permission. The App Ops feature was once there but pulled.
I know some Chinese Android phones, such as XiaoMi and Huawei, provide the app permission feature. Is the feature available in mainstream Android phones, such as the Nexus, Samsung, LG, HTC ... for latest version of Android 4.4.2 or upcoming Android L?
