Redmi Note 7 / State of play
-
thanks @AppLee for your reply.
I tried both the devel channel, and the stable. Even reinstalled (without wiping the personal data) to OTA-18. Without success, the non-lavender caller has an echo.btw, @stanwood, what do you mean, that you have "no echo anymore since OTA-17"? Did you also have an echo on the lavender?
-
@wurst I had some echo on OTA-16, but fix was released in OTA-17. So I confirm I have no more echo since then.
-
@stanwood may I bother you again:-) Did also the lavender caller hear an echo? Or both the lavender and non-lavender caller?
In my case (OTA-18) the lavender caller has no echo, the non-lavender caller hears himself. Also the mute microphone does not work on the lavender. Should I reinstall again, also with wiping the personal data? Or flash TWRP, make a factory reset including formating the data, and then perform the ubports installer again? How can I safe and restore the personal data (including the apps, their settings and storage data) on UT? -
@wurst Well I don't remind if recipients did hear an echo and I have no way to reproduce this now.
Maybe a more technical person would better help you.

@nico38 @Josele13 @stanwood
Hi, same issue than nico38, no GPS after a data wipe and fresh install. I have activated GPS (position=on), restarted the RN7 to "force" according to Josele13, but test_gps always returns error "gps interface not found :("
Restarted several times, waited long minutes, but gps always fails.
Maybe did I buy the RN7 that was owned by nico38
? -
@franzm Weird indeed. Was the device purchased with a Chinese global rom?
Did you well first installed UT with the vendor.img in lineage-16.0-20200226-lavender-vendor.zip ? (Which is required by the installer).
Indeed this file contains the appropriate firmwares for the Redmi Note 7 under Ubuntu Touch. -
@stanwood Global ROM yes, but not Chinese global...? or does "global" ROM means also Chinese? The ROM had ref. V12.5.1.0.QFGMIXM, available here: https://xiaomifirmware.com/roms/miui-roms-for-xiaomi-redmi-note-7-lavender/
In this page, I think Chinese roms are in a separate section.I just flashed the 'vendor' partition with vendor.img contained in lineage-16.0-20200226-lavender-vendor.zip (installer v0.8.8 does not ask for the vendor.img file, whereas v0.9.1 does). Test_gps still says "interface not found".
Original MIUI ref was : MIUI Global 12.0.3 stable
Do you think I should revert back to the original rom, and restart UBports install? I could now do that eyes shut...
-
@franzm Well it looks like a truncated instruction set is preventing your device from communicating with the GPS module. Maybe due to the original firmware, I'm not sure.
In any case the GPS is perfectly functional with the Redmi Note 7, I use it every day.
So, yes, I can recommend you to try to reinstall the original official rom (Android 9, NOT 10), then reinstall UT using the right vendor.img (see above).
I had solved a similar problem on my Nexus 5 some time ago (the screen was out of alignment). I reinstalled a newer, official stock rom, then reinstalled UT. The problem had disappeared.
If not, see if people on XDA could help you?

@stanwood Thank you for the advice.
What is exactly the original official rom?
My RN7 came with Android 10, but since I bought it by a well-known used phones seller, they may have upgraded the rom when resetting the phone.
Ok, I will try restarting the whole process, with a previous global rom with Android 9, switching from firmware v12.5.1.0 to older v11.0.1.0.
Let's go! -
@franzm Ok. I can't help you further on those technical issues, but wish you good luck, hoping to hear good news from you soon
Redmi Note 9S Stable
If God has a computer, it must be a GNU/Linux -
@stanwood Disappointed. I reverted back with stock "global" rom miui11/android9, tested the gps under Android which worked well, relaunched UBports installer v0.8.8 which does not ask for any vendor.img, then fastbooted vendor.img to the 'vendor' partition... and still no gps
But now the fingerprint security works! Before that it did not: a little sunshine in my cloudy sky.Developer

@stanwood Thank you anyway for your support! I will contact XDA people to understand why your RN7 has gps and not mine. Have a nice day (night?).

should it really be the stock rom? Isn't https://build.lolinet.com/file/lineage/lavender/lineage-16.0-20200226-UNOFFICIAL-lavender.zip sufficient, @stanwood ?
-
@wurst Indeed, this has the same name that the one I used.
But in mine I had only one file: vendor.img
UBports installer did guide me on all the steps. This file was automatically suggested to download.
So I can't help further now. Sorry.
Did you check here?

@stanwood said in Redmi Note 7 / State of play:
But in mine I had only one file: vendor.img
so, in fact it doesn't matter what there was on the RN7 before flashing UT, except that we need this vendor.img?
In my case, I thought, that the caller echo may be caused by the fact, that I had Android 10 (LineageOS 17) before flashing UT. So I planned to make a factory reset, install LineageOS16, and than with the installer again UT, and see if the echo still remains... -
@wurst I installed UT on my RN7 with Android 11 (LineageOS 18) preinstalled,
using the UBports installer. No GPS detection or echo issues so far, and the
device is working pretty well for the most part.In addition to @stanwood list, I would like to report what seems to be a bug
in the "Settings" screen. For instance, whenever I acess, say, the "Battery"
from the top bar (notch), click on "Battery settings" and then go back to the
general system "Settings" screen by clicking on the top left arrow by the side of
"Battery", one of the horizontal separating lines crosses the text of
"Security and privacy". A similar behaviour occurs if I reach the "Settings"
screen from other top bar functionalities in this way (this can be easily fixed
by rotating the phone to landscape mode, and then again to portrait).Even when I acess the "Settings" directly from the app menu, some of the text and icons don't
seem to be well-centered in between the separating lines, but I guess all this is
being already taken care of by the developers whose work I humbly thank

@franzm I don't know if you mean that the gps doesn't turn on in Ut or that the app doesn't find your position,
First you must turn on the GPS, try with the app and see if it turns on the GPS icon that changes to white.
If the colour changes to white, turn off the phone, then turn on the phone and test again with the app, it should work.
The gps should always be on, the app is the one that activates the location.
Never press Restart the phone, turn off and turn on the phone, it works much better.The mobile phone usually takes between 20 seconds and a minute the first time you connect, then on the same day it takes considerably less time, about 10 to 15 seconds.
Regards...

@josele13 I mean that 'test_gps" always returns "GPS interface not found :(" and that Pure Maps cannot find my position.
Yes, when 'position' option is activated, and I launch Pure Maps, the position indicator turns to white. I followed your instructions, turned the RN7 off and on (you don't mean 'reboot' don't you?), then waited several minutes, but Pure Maps cannot locate my position (indicator still white). And 'test_gps' still says "GPS interface not found :(".
Thank you for your help.

@franzm
Are you doing all of this outside any building in an open wide to the sky ground ?GPS won't work indoors because A-GPS is not handled under uTouch, and in good conditions, outside and open wide sky, it can take several minutes to do first fix.
-
@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.
