我的应用使用位置服务，并要求运行时权限打开过去六个月运行良好的设备位置，但是自上个月以来，当应用请求权限打开位置时，设备拒绝了该请求单击权限对话框中的“确定”按钮（https://imgur.com/32wdKHR）。
- 问题是在Redmi 4,5,6或7上可以正常工作时，受影响的设备占10-15％，主要是Redmi设备和少数三星设备（例如Redmi Note 3，Redmi 3S）。
- 问题从上个月开始出现，以前相同的代码运行良好（即使在Redmi note 3等中也是如此）。
- 手动打开该应用程序的位置权限。但是没用
- 在所有位置进行搜索，但找不到任何解决方案。 我该怎么办？
- 最近有任何更改禁止应用程序这样做吗？
