[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] schnodda123:
Hey!

Ive been noticing an issue with my device, since I think the update to MIUI 11 (but not sure).

Description:

- The compass (and other apps using compass like Google maps) gives incorrect readings, when put horizontally. When put horizontally and kept still, the compass will spin regularly ca 2 degrees per second completely independent from the actual pointing direction. When the phone is kept vertically the compass works normally. I have made a video displaying the correct reading when vertically, and the spinning when kept horizontally: https://youtu.be/xgC4fHqH4Ys

- When checking the underlying gyroscope functionality with "Sensor Multitool", I have come across what I think is an erratic z axis reading. When I spin the phone randomly, the gyroscope in the x and y axis registers adequate readings, but the z axis stays completely flat. I have produced a video showing this behavior: https://youtu.be/1dY_xdF5Nz8

I have found this thread from Aliosa007 ( https://xdaforums.com/showthread.php?t=3972249 ) that describes a very similar issue, but this user had recently flashed a new rom and the problem is attributed with the flashing. The users there assume the issue being a corrupt persist.img and most problem solving techniques involve flashing etc. But my phone is locked and not rooted. Could I also have received a corrupt persist.img during the normal update process recently to MIUI 11.

Currently trying to figure out, what the best way forward is. Wait and hope that this will be fixed with the next update or go the warranty route?

Thanks for helping me out with this one!

Hi.

I'm sorry I won't be very useful since I'm just having the exact same problem as you and don't know how to solve it... My phone isn't flashed either and my compass spins continuously.

I just wanted to know if you found a solution since your original post.

I also wanted to know if you tried factory resetting your phone ? I was thinking about trying that but if you already did and it didn't solve the issue, maybe I won't bother...

Thanks in advance.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] schnodda123:
Hey Tistou, thanks for your message. I haven't found a solution to the issue yet, unfortunately.

I tried factory resetting the phone but that didn't solve it. Did this problem just occur one day - or was it after you updated the phone? In my case Im not 100% sure it began after the updated and if it didn't, it could be an indication for a hardware issue.

I will keep this thread up to date in case I find a solution to the issue. But at the moment, I am out of ideas. I thought about flashing the phone with an alternative ROM and replace the persist.img. But currently the assumed risk/benefit keep me up from doing that. I'd assume sending Xiaomi feedback on that issue

Best,

schnodda
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Tistou52:
Hey,

well I couldn't really tell if it's related to an update : I got my mi 9T pro like two or three weeks ago and updated to 11.0.3 the day I got it...

The weird thing is that I noticed the problem one first time, and then two or three days later the issue solved itself without me doing anything particular and my compass started working normally again... And then two or three days ago it started spinning continuously again... I just hope it's software related and not an hardware issue...

I think I'm just going to wait for the next system update and if doesn't solve the problem I may send the phone back (but I don't wanna ... The phone otherwise is so great...).

I'll update the thread if I find something.

Good luck ;)
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] hoopsnake:
Hi there, I had a similar problem a while ago when going from custom rom Android 10 back to miui 10 Android 9. Pop up camera and gyro sensors wouldn't work so no auto rotate either. Simple fix was to flash the persist img in custom recovery, then go into stock camera app and it'll ask to calibrate, after than everything worked fine. This should work for you and everyone else with this problem hopefully.

Flashing persist won't wipe any of your data so don't worries there. I'll see if I can find the file I have it somewhere and I'll send the link.

So really the only way to fix this is to have compatible custom recovery with persist partition, flash the persist.img, but since you have a locked bootloader and stock recovery I don't think you have any options to fix this unfortunately, maybe fastboot rom through miflash? That didn't work for me but it might work for you.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] schnodda123:
Thank you so much for your response! That keeps my hopes up that I get it solved eventually.

I am currently not planning to unlock my bootloader, I am currently exploring to go the warranty route because that's the easiest way forward. But in case that won't work, I will definitely try to flash the persist.img. I will have to try to get my hands on the persist.img file!

Thanks again!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] hoopsnake:
persist.img is in the fastboot rom, so if you download that and extract you can get the img. You should be able to flash it thru fastboot using adb on PC with the command 'fastboot flash persist persist.img'. no need to unlock bootloader :)

I'm not gonna be near my PC for a while so won't be able to upload it for you :(
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] luizkun:
Sorry sir, but i think you cannot flash persist.img thru fastboot, because it read-only partition ,
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Tistou52:
I read several times that it must be flashed with twrp (dunno what that means)... But I also read that it makes you lose L1 widevine (dunno what that means either). Could someone enlighten me ?

And do you think the next MIUI update could fix that ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] schnodda123:
Not an expert on the matter. But a peripheral knowledge of the matter.

It appears to me that you are new to the matter. So I will use easy language.

TWRP is a so called "custom recovery" for Android that allows users to basically change the underlying firmware/system software (a process often referred to as "flashing") of the device. It is basically the entry point towards conveniently changing system files, that Android normally forbids you to change. To install a costum recovery, the bootloader of the phone has to be unlocked, so that the device can boot into the custom recovery instead of the OS directly. https://www.quora.com/What-is-TWRP-Why-is-it-used?share=1

Widevine L1 is a software part within Android that basically authenticates, that the device at hand is allowed to handle media files that are DRM protected (eg. within Netflix). When Android has been changed from the default configuration (by flashing a custom rom), the software part should revoke the authorization or restrict it. This behavior depends I think on the capability of the custom rom to trick widevine into believing that its genuine.(not so sure about that)

https://www.androidauthority.com/widevine-explained-821935/

Heres hoping that the next update will solve the issue! The issue isnt so dramatic to go the persist.img route. So I will patiently wait for the update. I will keep the thread updated.

Stock Pie to AOSP/Lineage Oreo/Pie Fix

Does not work on the H932 as tested by Mattgyver here

Use at your own risk on a h930

After testing for a month I am confident that I have found a way to "reset" the phone after flashing Stock Pie, fixing the many problems outlined here:

By following the steps below users will be able to flash AOSP/Lineage roms after having already installed stock Pie, doing so without any of the issues caused by the "permanent" changes left by stock Pie. AOSP/Lineage roms will work as if stock pie was never even installed.

INSTRUCTIONS

1. Follow the instructions here to flash the nougat rom I made over your current rom

2. Reinstall TWRP if it was wiped out on reboot (if TWRP remains for you, please let me know in the thread so I can remove this step. It stayed for me at least.)

3. Follow the instructions here to flash Stock Oreo over Nougat

4. After that you should be free to flash your favorite Pie AOSP/Lineage rom without issue! Youtube/camera/flashlight/lag should all be fixed!

I tested this on a US998, but I believe it should work for the H930 as well. If anyone tries the fix with an H930 please let me know in the thread.
[LG V30 Guides, News, & Discussion] tech_infinity:
So now camera and flashlight work for you on enforcing on pie aosp roms?
[LG V30 Guides, News, & Discussion] ^I'm_With_Stupid:
Yes. I've been using a pie Lineage rom (Liquid Remix) as my daily driver for the past month and no problems whatsoever. Completely stable.
[LG V30 Guides, News, & Discussion] Lucien1997:
interesting, just asking do we need to use only the zips? or kdz files will also work?
[LG V30 Guides, News, & Discussion] tech_infinity:
Why have you linked h930 oreo ROM though?

H930 ROM over us998 bricked [MENTION=5803877]HueyT[/MENTION] or someone else's phone it I remember correctly
[LG V30 Guides, News, & Discussion] ^I'm_With_Stupid:
I have a US998 and it worked for me. I believe this rom was confirmed working for the US998 even before I flashed it.
[LG V30 Guides, News, & Discussion] mattgyver:
So, you're basically just saying to flash back to stock nougat, then stock oreo, then flash some los-16 ROMs? Hmm.... I wonder if it'll work on an H932... I'll need a spare phone before I can try. can't even joke about bricking the only phone I have, when I'm 24/7 tech support.
[LG V30 Guides, News, & Discussion] mattgyver:
:laugh: :silly: Come on, [MENTION=3250376]ChazzMatt[/MENTION]. Why wouldn't a US998 file work on my H932 :silly: You know I'm not just a typical user ;)

I pulled the stock nougat and oreo files for the H932. Just figuring out which tmobile phone to buy as a spare in case I brick this. I need the 600mhz support. There are dead spots where I work, and I knew the second they got band 71 running because I had service everywhere.

Even still, I haven't really needed to worry about los. stock pie actually hasn't been terrible. I got used to it, which was surprising. I will try the method, just to see if it's possible. Like I said, just need a fallback device, in case something catastrophically fails!
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, you aren't typical user! But other people not as knowledgeable as you will read this thread perhaps months from now. When I answer a question, I try to also talk to general audience, many of whom may not even own this phone yet. ;)

For LTE band 71 on T-Mobile, you can always buy the

128GB T-mobile H932 V30+

($180 right now, which is decent price for "renewed" 128GB H932 V30+ -- which was limited edition offered by T-mobile during the 2017 Holidays. A lot of people don't realize the T-mobile H932 V30+ even exists...)

or buy another

64GB T-mobile H932 V30:

(less than $100)

Flashed this on my open market us998. Rebooted to recovery to make sure I hadn't lost TWRP, which I hadn't. Rebooted to system. Booted up fine, but couldn't get past setup keeps force closing. Button danced back to TWRP, and reinstalled the nougat zip, and bootlooped on LG screen. Back to recovery, and installed 20e,f, g, and h. Restored back up. Any thoughts on setup force closing?
[LG V30 Guides, News, & Discussion] mattgyver:
:(

Got the itch to flash something (that wouldn't send me to jail :D)

Confirming that this method

DOES NOT

work with TMo's H932.

Wiped everything on my phone, flashed the H932 Nougat FullStock zip then the H932 Oreo FullStock zip, both by [MENTION=9374982]weakNPCdotCom[/MENTION]

Once I got back to Oreo, I flashed los16. Camera crashes on open. Flashlight doesn't ever activate.

I at least wanted to try. Was definitely hoping it would work, if for nothing else, more up to date security patches. Oh well ..
[LG V30 Guides, News, & Discussion] tech_infinity:
Guess then you'll have to use aosp pie ROMs on permissive only for camera to work :(
[LG V30 Guides, News, & Discussion] mattgyver:
Back on stock pie for now. I only tried so that all would know if that procedure might work for the h932. I'd rather my device break than anyone else's :D
[LG V30 Guides, News, & Discussion] tech_infinity:
Hehe you make a good point. Especially because a less experienced user is more likely to break his phone if he tried, so good thing you tried it.

Thanks for trying and sharing :D :cowboy:
[LG V30 Guides, News, & Discussion] mattgyver:
[MENTION=5203339]^I'm_With_Stupid[/MENTION] - can you add to the OP that this doesn't work on the H932. Granted, no one ever reads the OP of most threads. :D
[LG V30 Guides, News, & Discussion] ^I'm_With_Stupid:
Sorry for taking so long to reply. Did you wipe your device before doing everything? Nougat zip should not bootloop no matter what. Also, you might not be able to restore the entire backup if it's a twrp backup. That might bring back the same problems as before. You might have to try and backup and restore another way, like using titanium.

Done! Thanks for testing.

[Android Software/Hacking General [Developers Only]] Edw590:
Hi. I'm no expert on Android (far from that haha) or Reverse Engineering. Though, I'm making an assistant installed as system app in a rooted Android and can also be compiled with the hidden and internal methods and classes so they can be used, like ITelephony, for example (https://github.com/anggrayudi/android-hidden-api) - btw, have you tried to mess with those classes and methods? (Sorry for my ignorance, I've no idea how it is to code/recode a ROM, what you need to use and stuff.) And anyways, I found something you didn't mention up there, so I'm unsure if you already know or not. From what Google says here (https://support.google.com/phoneapp/answer/9118387) in the "Screen calls manually" section, "Your Google Assistant screens the call and ask who's calling and why. You'll get a real-time transcript of how the caller responds.". Though, if it's their assistant doing that, not sure why that permission is on Dialer and not only on the assistant. Anyways, maybe that could be a good place to look at?

EDIT: Maybe also you (or anyone, of course) could look at sending DTMF tones over the call (I only made a quick search on Google, but there may be more that could help on this?). I think it's the same thing as it's inserting audio into the call. Though I can't be sure - btw, if it's really sending audio, then any Dialer app can already do that! But may not be that simple, so no idea at all. Maybe that's hardware thing and not software (>95% probable?). Just trying to give to ideas on where more to research.

Here (https://issuetracker.google.com/issues/36906273#comment107) it's said "I found this app, that can send dtmf after the call is made and active: https://play.google.com/store/apps/details?id=mobi.drupe.app (...)" - name: "drupe - Contacts & Caller ID" (just in case the app gets deleted from PlayStore and then people don't have their name to search for, only the package). If it's audio that it's being injected then it's possible, since that app seems to do it already, and the answer could be there too and might be good to look for the keys' frequencies on the code? Again, sorry for my ignorance on anything wrong I said. As I said in the beggining, I'm far from expert/experienced on Android.

I'll also be trying to search on how to send DMFT tones over a phone call. Could help, maybe. And if only a frequency could be sent for any reason, at least it's already cool to send some beep haha (preferably different from the ones of the keys or it might be confused with a key press by the other side, depending on who we're calling).

It's been asked more then once already and the answer was supplied more then once. Feel free to search the note 10+ forum here if you have further questions.. I am sure most of what you would/may ask has already been answered.

You can upgrade and downgrade firmware so long as the bootloader version is equal too or greater then what you have installed currently. Be mindful of what you flash, it's a one way street if you flash something with a higher bootloader version

The bootloader version is the 5th number when you count from right to left (starting at the far right as character 1).

As an example (red number is the bootloader version):

No it won't. Factory reset wipes the data and settings on your phone, but never changes the version of the installed OS.

On the other hand, a factory reset might help with some of the glitches you're experiences. YMMV......

[Touch Diamond, MDA Compact IV General] angus99:
I am on my second Diamond as the first one (Original HK phone from Expansys) had to be returned due fault. I now have a replacement (1.35 ROM).

The GPS on the original phone worked really well and started up quickly, even in doors. On the new phone the GPS is completely useless, to get it to connect initially took about 10 minutes standing in the garden. The last two mornings I have tried to use the GPS on my drive to work. Both times after 20 minutes the phone had not connected. This morning I even had the roof down.

I have searched the threads for a solution to this and tried everything including flashing the ROM to a later version, quick GPS, aGPS enabled and disabled, HTC GPS tool, Tomtom 6, Tomtom 7, Google maps and GPS tuner.

I'm now at a loss as what else to try, than sending the phone back for another replacement.

Is there anyway to set up the internal GPS manually either via software or registry tweaks or any other possible solutions to this.

Careful with one thing: GPS Autoattach (getting an IP from the network)

I tried this tweak with my diamond (enable or disable with schap's advanced config)

With Radio On (no flightmode) ans GPSAutoattach On, I get fixes as fast as 10 to 15s

With Radio Off (flightmode) and GPSAutoattach On, I get fixes as long as 40s.

Yes it seems weird because if you have no radio, you can't get an IP from network (so in this case GPSAutoattach is useless)

Turning GPSAutoattach Off (to save battery) I got no fixes at this moment (i gave up after 1min1/2 :p ) Radio On or OFF

Perhaps something wrong on ROMs about the GPS/AGPS.
