根据日志发现大部分机型集中华为、荣耀、vivo
setZoom 设置的值为小数时，使其为一位小数试试
handleZoom(type) {// 0缩小 1放大let z = this.currentif (type === 1) {if (z >= this.maxZoom) {return this.$msg('已达到最大缩放级别')}z = +(this.current + 0.2).toFixed(1)if (z > this.maxZoom) {z = this.maxZoom}} else {if (z <= 1) {return this.$msg('已达到最小缩放级别')}z = +(this.current - 0.2).toFixed(1)if (z < 1) {z = 1}}this.current = zthis.$emit('zoom', this.current)uni.setStorageSync('cameraZoom', z)},
