Redmi Note 7 / State of play

wurst · 13 Sept 2021, 11:35

I installed UT on lavender via the installer. But a caller from Android hears an echo. Switched from stable to devel channel. UT was updated (version of yesterday), and also updated all apps. But still the same, echo for Android caller. I thought the echo problem was fixed. Can someone please confirm that there should be no echo. Should I reinstall UT? Or how can I fix this caller issue?

@wurst Well, I have no echo anymore since OTA-17.
But you can try this:

setprop persist.audio.fluence.voicecall false

Not sure if you have to make this after each boot (best is to try)

wurst · 14 Sept 2021, 06:54

@stanwood thanks for your reply. Unfortunately this didn't help. I will try a clean install. How can I see on which OTA I am?

Hi @wurst

You can see the current version in the "system settings" > About

wurst · 14 Sept 2021, 21:36

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?

stanwood · 14 Sept 2021, 21:57

@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.

wurst · 15 Sept 2021, 14:17

@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?

stanwood · 15 Sept 2021, 17:22

@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 ?

stanwood · 8 Oct 2021, 20:19

@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.

FranzM · 8 Oct 2021, 21:22

@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...

stanwood · 8 Oct 2021, 21:38

@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?

FranzM · 8 Oct 2021, 21:56

@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!

stanwood · 8 Oct 2021, 22:39

@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

FranzM · 8 Oct 2021, 22:48

@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.

FranzM · 8 Oct 2021, 23:02

@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?).

wurst · 9 Oct 2021, 09:06

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).

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 ?

stanwood · 9 Oct 2021, 09:37

@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
