You can enter GPS settings-network assistance is also turned on synchronously, if there is still a problem.

I suggest you upgrade to the development version of MIUI with a wire brush, and try to solve it. You can refer to the following line brush tutorial:

1. First, you download a newly developed version of Mi2 brush package from Xiaomi official website. This is the link:/topic-mirom.html.

2. During downloading, please back up the data, enter recovery (shutdown, press and hold the volume increase+power on key to enter recovery), and empty the cache, user data and all data. The computer turned to a better driver. This is the driver link:/thread-3104435-1-1.html.

4. If you are not familiar with brushing, you can refer to the brushing video tutorial made of rice flour:/v _ show/id _ xnteymjq1mzi4.html.

Thank you for your support and wish you a happy life!
