示例代码：

onLaunch: ()=> {  
            console.log('App Launch')  

            var ll = wx.getSystemInfo();  
            console.log(ll)  
            var lk = uni.getSystemInfo({  
                complete: (res)=> {  
                    console.log(res)  
                }  
            })  
            var lj = uni.getSystemInfoSync()  
            console.log(lj)  

            setTimeout(function(){  
                var ll = wx.getSystemInfo();  
                console.log(ll)  
                var lk = uni.getSystemInfo({  
                    complete: (res)=> {  
                        console.log(res)  
                    }  
                })  
                var lj = uni.getSystemInfoSync()  
                console.log(lj)  
            },1000)  
},

操作步骤：

uni.getSystemInfoSync()，第一次安装或者热启动得到的打印是异常的值

预期结果：

bug描述：

在APP.vue onLaunch 或者其他 xx.vue 里面调这个方法
var ll = wx.getSystemInfo();
console.log(ll)
var lk = uni.getSystemInfo({
complete: (res)=> {
console.log(res)
}
})
var lj = uni.getSystemInfoSync()
console.log(lj)

第一次安装或者热启动得到的打印是（该打印是异常的值）：
