Redmi Note 7 / State of play

FranzM

@keneda I don't think that this is the point.
When I launch 'test_gps' on my Nexus 5 with UT, from exactly the same location (in my wooden house), it displays lots of init infos, such as "device info / name = loc_api GPS module", and then starts tracking satellites, and may or may not find them.
I already tested the GPS location with my Redmi Note 7 that initially came with Android 10, and the GPS worked well, still inside my home. Since I flashed the RN7 with UT, 'test_gps' stops immediately with message "GPS interface not found :(", and therefore does not initiate any tracking step, which let me think that it's a matter of software/halium/drivers issue and not a question of location.

@franzm Yes, this continues to make me think at a firmware issue.

Are you on the French speaking Telegram UBports group?
I can try to send you the right vendor.img file that worked for me. (I can not through this website)

Edit: Did you well UNZIP the LineageOS
lineage-16.0-20200226-lavender-vendor.zip file?
Unlike a LineageOS installation, here the file must be unzipped before to be used in the installer.

@franzm I mean restart Ut, but not by pressing restart, you turn off the phone and then turn it on.

@stanwood Thank you again for attempting to help me.

Yes, I unzipped the lineage-16.0-20200226-lavender-vendor.zip file, and flashed the 'vendor.img' file to the 'vendor' partition. I suppose it's not worth sending your 'vendor.img' to me, since it should be exactly the same one. Or does yours may be different?

Your question makes me doubt: the installer v0.8.8 does not ask for any vendor.img file, so after installation, one have to flash manually the vendor.img. Is this correct?

FranzM

@stanwood In Settings / About / OS Ubuntu 16.04 / Details, should the 3rd section ("Partie de l'image du peripherique" in French, could be "Vendor partition" in english) show a ref. to the lineage-16.0-20200226 vendor file?
On my RN7, it displays: 20211005-20810

stanwood

@franzm Ok nice. Well, once you have installed UT, the installer won't ask you for the vendor.img anymore - on any future installations - since it's already there. This request occurs only at the very first installation.

Concerning your second point, I don't have the exact same data than you (I'm on the stable channel).

Here is what I get:

Not sure it will help you though...

@josele13 Hi,

Please, could you go further with your explanation?

On your Redmi Note 7, if you restart your mobile on purpose, do you loose the GPS? I mean: after rebooting, does test_gps return 'GPS interface not found'?

And after that, you launch an app which requires the GPS, making the location indicator turn white, then you put your phone off (by a long press on the power button? or just screen off?), then put it on, and GPS starts working? (I suppose after having found satellites)
When it works, what does test_gps say?

I tried soft reboot, soft shutdown+restart, hard reboot (long press on power), simple screen off/on, but my GPS never works, and test_gps always returns "GPS interface not found".

I do not understand why it does not work on my RN7

Josele13

@franzm Pressing the restart button is not enough, the phone must be turned off completely,

Turn on the GPS
Open an app to locate you
Turn off the phone
Turn on the phone and use the app again to locate you,

The GPS icon should turn on in white and in 1 minute it should find your position,
you have to be outside any building.

Regards...

FranzM

@josele13 Ok, thank you for the process. But it does not work on my RN7.

FranzM

SOLVED

I read through all the GPS topics on the Telegram channel, and understood that 'test_gps' could report "GPS interface not found" even when the GPS is working!

I did new tests, left my house, waited a few minutes outside and found that the GPS was working (Pure Maps or Google Maps). And indeed, in this state, 'test_gps' keeps saying "gps interface not found"... I thought it was trustworthy, but it is not!

So everything is fine, now.

Thanks to @Josele13

@franzm said in Redmi Note 7 / State of play:

left my house

Told you try that...

Josele13

@franzm You're welcome, I'm glad the gps is working, enjoy your new mobile with Ut.
