GPS Issues on NOS, LOS and MIUI Nougat - Xiaomi Redmi Note 3 Questions & Answers

Hi guys,
I'm having a super slow gps fix no matter what i try
1. Flash latest or stable firmware
2. Edit gps.conf
The slow is like i takes almost 5 mins to get a 3D Fix or locked position.
But i notice this happen since nougat build. Miui official on marshmallow work extremely fast to get a fix. But whenever i use custom rom like NOS Oreo or Nougat, LOS Oreo or Nougat and also MIUI Nougat (Epicrom) Latest 9.x still have this issues
Im on Kate, official unlocked bootloader. I wonder is there any method i can try?
Any reply will be thanks:highfive:

Darren Lim

NOS have a new update on (24th) , and the chg log mentioned there is something chg related to gps, u guys tested? Gonna release the fix soon. The reason i haven't release is because it might cost lost to imei. I try to find a method to prevent that. And need more testing. So plesde be patient ya

My GPS started working properly,
I did try flashing firmwares but didn't help. I flashed full stock rom(global Dev 8.1.18) and then flashed cosmic os and now having no issues with GPS.(I also use GPS status and toolbox).
I haven't tried nos

Yes i did know this method works., But if u dirty flash an update again ur gps will broke. So u need redo again everything from beginning. It's no a good method tho but it work ?

Dug up the Github commit, here's the dev's quote:
https://github.com/nitrogen-project...mmit/5a9e84251696bb48e8fe184784226604efdf6f6c
[haggertk]:
* During bring-up of O, GPS was exhibiting different behavior from
N -- an appropriate number of satellites would immediately lock,
but a fix would not resolve for 30-90 seconds. Digging up this
change from the L-era allows GPS to resolve a fix in a nominal
amount of time.

Hi guys,
Any progress on this issue? Anyone tried latest NOS maybe? I switched back from NOS Oreo to NOS Nougat because of this...

Ok guys,
Please take note this will make u lost your IMEI somehow mine is missing but i did have a backup so i can restore it anytime. Without IMEI it doesn't affect me at all.
This method is weird so, backup before you do it. Not responsible for anything happen
1) boot into FASTBOOT
2) connect to computer use ADB and key in this
fastboot flash modem NON-HLOS.BIN
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
The nonhlos.bin can be found inside a official miui rom and flashing the non hlos is not necessary.
Test your gps after that it should work. Please report back

I fixed gps problem by installing F-Droid,than GPSfix extension,selected my country and voila...When u're in house etc. or when its clody weather its hard for GPS for 3D fix. Btw Im on Cardinal latest Oreo 8.1 build and 8.1.11 miui firmware.

This method doesn't work. And it only work for one days. And ppl like me have no time to wait for it to fix before moving
Some ppl lucky enough that they dont even have any bugs. I actually suspect its hardware compatibility issues. Blame xiaomi for that maybe? Hahaha

simple, use Device only as agps given problem often (depend on the agps mood?).
I also removed miui built in compass as it shown compass accuracy high to low from gps test app (suspect this causing the gps locking issue too).
now waze locking every time within few seconds.

I assume you are talking bout miui in nougat. So you mean after u disable compass and use device only mode the gps jssues is fixed?
