您好，您这边先进行更新最新版本的apk：https://mmpaypublicbucketpackage-40035.sh.gfp.tencent-cloud.com/wxpayface-release_sdk_2.12.320.956_legu_aligned_signed.l3igj0qy.apk。然后如果还有白屏的情况，是否能提供视频，或者图片。最好有设备SN，和复现时间点
谢邀：
安卓微信刷脸支付，没涉及到，没经验给你意见。sorry
情景是调用先 getInstance 等，最后 getWxpayfaceCode 拉起刷脸页面，然后取消 release释放掉，再调用拉起就人脸识别窗口就会白屏（同样也有经过getInstance等操作）；调用WxpayfaceUserInfo时候取消再拉起就不会出现白屏情况，功能正常（经过同样的getInstance等操作）。
