Improve your POCO GPS experience
"We are here with a new tip related to GPS. If you wanna improve it, you can make the following tweaks ...
Before we proceed. A small note on how this works.
To get a position fix, the GPS chip in a device needs to acquire the signal of at least three satellites. If the GPS chip is unaware of the identities of the satellites and their orbits this task can take several minutes. To speed things up a device can get information about satellites and their current location from an A-GPS server on the Internet. The single piece of information the server requires is a rough location estimate from the device. Usually a device is not aware of its rough location but it knows other things that can help such as the current cellular network id (MCC and MNC) and the id of the cell that is currently used. This information is sent to the A-GPS server on the Internet that then determines the location of the cell or network with a cell id / location database.The location off the cell or network is precise enough to assemble the satellite information that applies to the user's location which is then returned over the Internet connection. The satellite information is then fed to the GPS chip which can then typically find the signals of the GPS satellites in just a few seconds.
it can be seen that Xiaomi uses a third party SUPL server in MIUI. The address of the server is 221.176.0.55 which appears to be China Telecom’s AGPS provider.
Now POCO wasn't even launched in China. And using a server based out of China might not lead to the best performance/experience while using A-GPS
Here is how you make the changes to optimise this .
To access the option, users need to search under MIUI settings for ‘A-GPS’ (without quotes)

Once we click so . We will get the following screen

Make change to reflect as so

Change the following as to these :-
All Networks
supl.google.com
7276
Click on "More" at the bottom and click on Save.
Easy alternate :- Click on More at the bottom and then click "Reset " . This should get the Google server settings by default. Then hit " Save" under "More".
Thats it. The phone will now use Google servers which will help anyone using the phone out of China to have a better experience with GPS
