GPS issue since nougat update - Xiaomi Redmi 4X Questions & Answers

I face GPS issue (I mean that gps doesn't start at all) while using my phone with lte connection. I have no problem if using my phone with only 3g. I've tried everything but no solutions! This problem started with nougat MIUI update and nothing changed using every single rom whether MIUI or custom.
Is someone facing same issue? Are there any solution for that?

miui forum if full of posts of people with GPS problems with nougat rom and redmi 4x.
As you said, the only solutions seems to be:
1) use of 3G (or aereo mode) instead of 4G when you need GPS
2) install an older ROM with Marshmallow.

MIUI WiFi problem in my Milestone

I have problem on my Milestone with MIUI WiFi.
Every other ROM works just fine (connects immediately thorough WiFi with the internet). Unfortunately every version of MIUI don't
I tried 1.14, 1.21 v2, 1.21v2, even 1.26 chinese. All those versions doesn't want to connect via WiFi.
I've done 3x wipe before and after instaling MIUI.
I've installed MIUI from several ROMS, official + vulnerable, 2.2.1. GOT, 2.1
and always with the same result. WiFi won't connect.
There's short thread about it on xda involving different mobile and using clockworkmod recovery + rom manager, but it's not confirmed and it used to not work on Milestone. Could cause damage, so i droped tryin in that way.
Anyone got any idea why WiFi doesn't want to work in MIUI on my Milestone?
Is there any app tool to discover the cause of lack WiFi connection? Maybe i can run it on my MIUI and show to some dev who will now what certain logs mean ?

Sad you never got an answer to this one - right now I have the very same problem. Happened after the last Miui update.
I have nothing but hope it will get better with the next one.
I have the same problem. On newest version of MIUI (1.5.13), and the 1.5.6 was the same. On 1.4.29 everything was fine. Now wifi is connecting, getting IP, and nothing happens (disconecting)
help pls, anyone can find the fix? where to post this problem ? I dont know chinese
Is your router N? If so, try to change it to work as G only. This is the only way I can make CM7 connect properly with my router, unfortunately, perhaps this helps you guys.
my router is Linksys WRT54GC, wpa (not wpa2) personal, tkip, b/g (not n)
so I dont know if "g only" will help, normally on every rom there is no problem, but from MIUI 1.5.6 problems started. Strange that this happens not to everybody, but to some of us only.
I can confirm that the bug is MIUI related cause I don't have it in CM7 on my HD2.
Sadly I couldn't find any solution yet.
In my case it was caused by luca/froyomod's dsi fix update.zip which I applied on miui, whole radio (wifi + data) wasnt working properly after that. Now I do it manually, or using dsi fix for miui made by eyebee in his thread, and great rom by the way. It feels much snappier, and better multitasking, lots better than pure Miui. Feeyo's, luca's, zeppelinrox's tweaks and other applied by eyebee do the great job on this rom. Great alternative for cm7. Of course kabaldan does also great job. Ok, EOT

I'm expecting exactly the same problem at the moment. Have You solved this issue? I think it is MIUI connected becouse I am on SGS with the same issue.
Same for me on 1.7.29 version.
This version of MIUI caused me alot of trubble.
First i bricked the phone (like an noobie formated system and bootloader) okay some how i got it fixed. Then I installed 1 version older 1.9.30 which caused my phone keept restarting due wifi power on (after restoration with included app) now my phone keeps restarting again (after update) and im really not in mood atm for any thing =/ cant get my apps backedup since phone keeps restarting.
is there any way to disable wifi without booting into android?

Problem with GPS in non stock ROMS

Hi togehter,
I bought a Galaxy S3 Mini i8190N from an offer here in germany last month, the phone has a sim net lock. First of all I am experienced with flashing custom roms. But for my issue I never found any available topic.
I had no problem rooting the device and I can also install and run several custom roms, but for non stock roms I never see any satellites in view (GPS Test, GPS status & etc.) Everything else runs fine, WLAN, BT etc.
I tried to change the ntp pool settings to germany / europe, but this doesn't help (Faster fix, also manually system/etc/gps.conf).
In stock roms / custom stock roms GPS is working fine and I get a fast fix, I see a lot of satellites.
What I also tried:
Going back to orignal stock rom. Made a hard factory reset.
I tried flashing with Odin and also with TWRP v2.7.1.0 20140612, but this also does not fix the problem
Before installing non stock rom, I made a factory reset and deleted cache/system/davlik cache, but gps is never working. The symbol is appearing, if a app wants to access GPS and I also changed gps settings to high resolution.
Does anybody else have same problems?
Roms I tested Carbon, Omni, Slimrom, Cyanogenmod (MacLaw), I also tried Omnirom from goldenguy
I can provide more informations, if someone has an idea about it.

Update:
Hi together,
I again started to understand why GPS works fine in roms like R-Mod3 (Cutstom STOCK) and does not work for all kitkat roms >=4.4.2.
Enclosed you find the debug logs of google maps and gps test for omni-4.4.4-20140801-golden-HOMEMADE . In both apps I get errors in debugging. Can someone help me understand the problem here?
I guess it's a driver issue for android versions higher than stock rom.
Have you tried CM10.1?

MI5 No service / emergency calls only after MIUI 8 update from Android 6-unlockedBL

hi, my xiaomi mi5 32gb/3gb ram had android 6(no ideea about version) and unlocked bootloader, bought from china with european version of the rom, gapps installed.
everything worked perfectly, no drops in signal, nothing to complain.
i updated to MIUI 8 Android 7 official and after that the signal dissapeared, the only moment i had signal was when i put a new simcard in the phone, and only for 2 minutes.
Then i flashed with XiaoMiFlash : gemini_global_images_V8.2.2.0.NAAMIEB_20170407.0000.00_7.0_global_95e92d22eb
-- the problem stays: no service/emergency calls only.
i have good 3G 3-4bars/4G sometimes, when it comes to signal in this location.
nothing helped.
flashing xiaomi-miui-hellas-7.0_gemini_V8_XTRV_7.4.20 with TWRP Recovery also didn't help my problem
Now i am with a phone with no signal, could you please give me some help to solve this?
i've seen a lot of people in this situation on forums, so a solution would be very good.
Perhaps the settings from the *#*#4636#*#* Hidden MENU, this way i would do it the way it is on a working phone.
Thanks, greetings. Dan

Custom ROM WIFI won't auto connect

Hello, i'm experiencing issue with wifi.
The AP's are detected, but system is not auto connecting to them.
I must click on connect, then phone associates with AP and everything is OK.
I tried forget network, but it did not help.
My ROM is AospExtended-v4.4-OFFICIAL, Android 7.1.2 (I tried latest LineageOS, but the issue persisted).
Phone Lenovo A7000-a.
In Lenovo stock ROM (Android 6) phone auto connected within a few seconds.
How should i fix this?

You think it's you who is supposed to fix it?
It's a ROM bug. How are you supposed to fix it on your own?
We devs need to do it. And currently we don't plan to.
By providing custom roms to you guys for free, and wasting our time, we are already doing so much for you. If you enjoy so many things in a custom rom like that, then you should also prepare for facing bugs. That one is very very minor.
Also, comparing custom roms to stock roms is a cyber crime.

Cant Turned on WIFI/BT, Already Flashed for BT still not working

Hi , its been a year since i bought xiaomi mi 9-global rom(128GB) and all work properly.
if im not mistaken the first rom when i bought is MIUI 10 , then the last time i update if im not mistaken is around september in MIUI 12.02 for the latest security patch.
Suddenly problem occurs recently maybe around a week. where my Wifi & Bluetooth disconnected by the system and cant be turned on but it fixed it self as i restart and now its never fixed.
I already some of fixed below :
- Restart devices
- Wipe all data
- Factory reset
- Try to flash the ROM from official one MIUI 12.02
- Following some tutorials that reset bluetooth and wifi settings
- Try downgrading MIUI version to 11
but still didnt work the Wifi & Bluetooth setting always crash & cant be turned on , try CIE or CIU test found out that the proximity sensor also didn't work.
I also tried some tutorials that do in EDL mode to install persist mode but its not working due to the Authentication it says" i dont have the permission"
Is there anyway i can fixed the Bluetooth & Wifi in this device?? The Mobile Data is still working and other features still working except Proximity Sensor, WIFI, Bluetooth.
Is the only way is to let the xiaomi store fixed it?? this is my only phone so i need it alot and the office store probably going to take long since pandemic.
Please help me Xiaomi Pro's out there :crying:
Edit :
- my xiaomi account already match with the phone the proof is i can unlocked OEM using the xiaomi. But it seems i still dont have permissions to flash EDL.

I think it's safe as miui could be.
But be shure to follow step by step and take right rom version. If it's working you can flash original miui or custom roms.

Thanks for the suggestion, after i tried to flash to EU ROM i got new MIUI version which 12.04 , in global its 12.02. However the problem still happening or still remain unsolved. The bluetooth & wifi still cant be turned on, i tried on CIT it also not working and everytime the i try to open wifi & bluetooth settings , the settings always freeze and crash probably because it error. Is there any other solution you can provide?
Thanks

I think, if you have done a really clean flash with formating data, that it's a hardware problem.

yes, i did i already follow the instructions & having no error at all for the ROM and other stuff except the WiFi & Bluetooth.
But for me its just really weird, my phone looks still great from outside no bend, dent, or crack it never fall as well.
The problem starts occurring by itself like the system is forcing the Bluetooth & WiFi to off then at some point the WiFi is connected but not transferring any data after restart everything fixed then its not working at all, which when i tried to turn it on it will freeze or the system not responding or off by itself.
btw appreciate your answer, i'm still waiting for other solution if possible :crying:

Are you shure that you've got a global version. I had nearly the same probs as I've flashed the global on my eu hardware.

In my personal opinion there're 2 possibilities
Damaged hardware
Or
Modem Partition wrong or damaged
MODEM or RADIO - the phone's radio
Also called baseband, it is responsible for signals and on older devices may control wifi, bluetooth, and GPS (on most newer devices, these are handled by the kernel and ROM). Upgrades are country dependent and may improve or diminish battery performance, network signal strength, and roaming capability. It is also sometimes required to have a minimum Baseband version to use a ROM so that the RIL will play nice with the Baseband.
Modem firmware is a mini-OS for the cellular radio chip which has its own processor. Firmware is a general term, firmware exists for a lot of things on phone. The wireless chip for WiFi, GPS, and Bluetooth often has a firmware as can the GPU core among other things. These firmware files are usually located inside the SYSTEM or VENDOR partition. The modem firmware is special because it has its own separate Baseband Processor (BP) so the firmware is left out of the system image in its own partition.
Modem is not an Android-specific partition. It is tied to the hardware of the phone, but the kernel has a code allowing Android to interact with the hardware. But the baseband processor (BP) - which runs modem and is responsible for all communication through mobile networks e.g. call, SMS and internet - is totally isolated from Application Processor (the one we call CPU) and is not governed by Android kernel; it runs an independent RTOS.
May it helps you for getting a solution....

Maybe i just dont have any other option except to fix in mi store.
Once again thanks for the help :fingers-crossed:.
