[Off-topic] xdazevv:
Hi folks,

First this: please let me know if this post is not appreciated here, and if there is a better place to put it.

Short version:

My company is looking for an allround AOSP developer who is comfortable going from C++ to Java, from init to stagefright, from vold to art and surfaceflinger to bionic. It's proving very hard to find people with this particular skillset, so I decided to just go to the place where all is happening: XDA.

Somewhat longer version:

We are building a platform where we run AOSP at scale inside a cloudy system, where graphics (GLES2) and multimedia (audio/vido) is offloaded to a custom thin client running on STBs. At the core of this product there is our own port of AOSP, which is basically goldfish with some customization to allow it to run on an x86_64 VM instead of an ARM SOC. We have *tons* of cool work to be done on this platform: implementing custom services, optimizing resource usage, tweaking UI's, etc.

We are looking for someone who is strong at graphics and multimedia, is comfortable with both C++ and Java, and most important of all: who has tons of experience hacking their way around all levels of AOSP. We are located in The Netherlands, although with the current COVID situation I guess there is no hurry to move. Being in .eu time zone is a pro.

If you are interested, please drop mail me at xda@zevv.nl and I'll be glad to answer any questions and provide more details.

Thanks,

Ico

[Xiaomi Mi 10 Lite  Questions & Answers] zizouli:
The phone is supposed to support dual-frequency GNSS.

Can someone use GPSTest (https://play.google.com/store/apps/details?id=com.android.gpstest&hl=en&gl=US)

and show a screenshot that demonstrates that the phone can pick up both frequencies?
[Xiaomi Mi 10 Lite  Questions & Answers] DVC1985:
Attached screenshot, you can see L5 and E5a in use there.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Looks like the screenshot got lost in the mail ;-) But yet I can confirm that dual-frequency is supported.

B2a too
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
Dual-frequency GNSS works. Positioning in general seems to be quite fast and accurate outdoors, also in forests.

Unfortunately it does not record carrier phase data with GPSTest or other apps (only outputs zeroes), so post-processing (PPK or others) are not usable. Does anybody know whether a custom rom can help with that?
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
I've seen it couldn't output "Navigation Messages", is that what's missing ? The Mi 8 could do that though I think. Is it really worth doing post-processing with an Android phone though where you're going to be limited by the poor antenna ? What post-processing tools do you use ?
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
You're probably right about the antenna. I wanted to see how far you can get with this phone. For some of my applications it could be useful to have sub-meter or at least the best accuracy available.

I wanted to use https://jason.rokubun.cat/#!/
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Thanks for the link, they do indeed mention Android Smartphones under https://jason.docs.rokubun.cat/examples/ and give instructions on how to log data with GNSS Logger (GNS Logger v3 keeps crashing on me, does it work for you ?). They don't mention Navigation Messages that the Mi 10 '(and all 765G devices) is not capable of but "measurements" should be ok. Did you activate the "Full GNSS measurements" in the Developer Options ?

PS - I tried to create an account on Jason but I'm not getting the confirmation email. I tried "forgot password" and got an email but it won't reset. Looks like the site might have a few issues !
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
GNSS Logger always crashed on my phone, too. I have successfully used "GNSS/IMU Logger" as well as "GPSTest" instead (I prefer the former but since the last MIUI update (12.1.3) it has some bugs). I have enabled "Full GNSS measurements" in the developer settings.

The site worked just fine for me. At first files from the GPSTest app were not readable by the engine but the developers changed this immediately. They have also been very fast and helpful with my problems so far so maybe try contacting them via mail.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Good to hear, so what phone were you using when you got your data processed by Jason ? I received the email so I'll give it a try with both GPSTest and GNSS Logger v2 with my Mi 10 Lite just in case.

EDIT : so the GPSTest recording was...empty so same problem as you it seems (or I did something wrong while recording) but the GNSS Logger file is 1.8MB and is currently processing but stuck on "Looking for closest CORS station" so I'm not sure what's going on.
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
Ah sorry, my message was unclear. I have produced valid rinex and raw log files with the Xiaomi Mi 10 Lite but the fields with the carrier phase data were empty. Jason then still processes the files but the output data are not helpful, with positions way worse than what a standard gpx recorder delivers.

Jason usually didn't take long with my files.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Gotcha, I opened the log with excel and the CarrierPhase fields are indeed empty. Is that why we get the " Could not set-up parameters for PPP processing: Cannot perform PPP on Rinex because SP3 orbits for 2021-01-21 16:00:17.429569 could not be found " message in Jason ? That sounds more like a CORS station problem but anyway it won't help with our problem.

The result was indeed poor, worse than what I was seeing on GPSTest actually but I think GPSTest shows the "Android Position", i.e. fused GPS/WiFI/4G
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
By the way, which rom are you using?

I don't use 4G or Wifi for positioning.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Stock ROM with Miui 11.0.4.0

I'll try turning off data to see what that does to the position. It might be using the accelerometers too to keep it steady.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
About the empty CarrierPhase data fields I wonder if the data isn't being made available differently after reading the paper made available here : https://www.researchgate.net/public...g_Xiaomi_Mi_8_Dual-Frequency_Raw_Measurements

Where it says : " Not all available public methods in these two classes are actually in use or of interest for satellite-based positioning. In fact, some variables (e.g., ‘CarrierPhase’) have been deprecated starting from API version 28 [11]"

EDIT : ok, what we need is the "AccumulatedDeltaRangeMeters" and it is indeed shown as 0.0 on the Mi 10 Lite

Looking for some Mi 8 logs now, I'm pretty sure I've seen some somewhere !
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
See here for example:

https://www.kaggle.com/google/android-smartphones-high-accuracy-datasets

From the "awesome GNSS" list. You can also find a list of device capabilities there:

https://docs.google.com/spreadsheets/d/1jXtRCoEnnFNWj6_oFlVWflsf-b0jkfZpyhN-BXsv7uo/edit#gid=0

The Mi 10 Lite 5G is supposed to support carrier phase data /accumulatedDelta. It just seems like they are not calculated.

I'm sure you know the GPSTest group:

https://groups.google.com/g/gpstest_android

I'll leave the link for other interested people.
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
Yes I'm there too ;-) I just mentioned the GeolocPVT app, I managed to build it starting from the .aab, what a hassle ! Unfortunately it can't get a fix with the Mi 10, maybe because of the lacking ADR data ?

Talking of which I ran GNSS Logger v2 on a lowly Redmi 9 and...it logs ADR data ! I'll see if I can post-process some data with Jason.

Thanks for the links for the logs, the video presentation was interesting too. Do you know what the "Ground Truth Data" is ? A geodetic receiver getting RTK corrections maybe ?
[Xiaomi Mi 10 Lite  Questions & Answers] webvan:
I wonder if the Mi10 will ever get proper ADR data...have you had other Android phones that provide that data ?
[Xiaomi Mi 10 Lite  Questions & Answers] Monticola1:
Sorry, no. I didn't check with the Realme X2 Pro and now no longer have it.

Hi:)

So as you guys can see, when the first time you turn the phone on you can see the Theme app or Mi Store but when you choose your region they disappear! why?! That's because some services are specially edited for some regions!

Here I tell you how to make these apps UNDISAPPEAR :D

before we start please hit the thanks button :D

OK, Here we go:

1- Open Setting

2- In the search box, type "Region" and hit the search button

3- Open Region

4- Choose India

5- Close settings

Now if you go to home screen and swipe pages, you will see Theme app and other apps that have been disappeared.

Also you will have some special features in some apps like Music app :D

Done.

Notes:

1- If you change region, everything will be the same as before

2- don't worry about changing Region to India because nothing will go wrong even apps or websites which depend on your region or time zone because they check your location not region of your phone!

Don't forget to hit thanks button :laugh::fingers-crossed:

[Sony Xperia 1 II Questions & Answers] Moze666:
Hello,

I just bought a pair of really good headphones, Beyerdynamic DT 1990 PRO, and the sound is very low on max setting. I don't know why, I don't know how... My other Bluetooth or other headphones work great and sound is there, but with these and AMP/DAC Dragonfly RED and a Dragontail (USB to USB-C adapter), I get no sound that I want and that bothers me. If something is wrong or it just doesn't understand my setup or USB-C is a wrong hole for the music to play through? I have searched and read threads and websites with no result.

So, I am asking you for suggestions, anything goes. I tried a couple of sound boosters and they just make my music sound like crap, tried all the settings in the phone, I don't know what else is left to do...

Thank you in advance.
[Sony Xperia 1 II Questions & Answers] CactuarBen:
DT1990 Pro has resistance of 250 Ohm what makes it a fairly hard model to drive without an external amp. Dragonfly should be enough though. Is your PC driving them well? Maybe Sony can't power Dragonfly sufficiently.

Hi everyone,

I just got my bramble today. And yes, the first thing I did, was unlocking the bootloader and rooting it.

Here I tell you how I did it.

You need a ADB/Fastboot suite installed and this rooted kernel.

Section 1: Unlocking your Bootloader Unlocking your Bootloader will erase all your data - so best case is a brandnew and clean bramble...:

1. Go to settings - "About phone" and tip 6 times on "Build number" until you see "congratulations, you are a developer"

2. Go to settings - "System", tip on "Advanced" and then on "Developer options". Now you can see "OEM unlocking". Enable it (yes it warns you about security and stuff... It´s your choice - I did it :D).

3. Install Adb and Fastboot suite and scroll to the adb-folder inside your windows explorer and when you are there, copy the rooted boot.img to your adb-folder (you need that for section 2).

4. Right click + shift on the white background of your adb-folder "open power shell window here"

5. Reboot your bramble holding vol- and you will enter the fastboot screen. Connect your bramble to your pc and type in your power shell window the following code:

./fastboot flashing unlock

and hit enter

6. Your bramble will warn you that unlocking your bootloader is insecure! And one really important thing again: This will format all your data

7. Use the vol-/vol+ keys to accept and violla, you unlocked your Bootloader!

Section 2: flashing the patched boot.img

1. Luckily you already copied the rooted boot.img to your adb folder and you are still in your power shell window. That gives you everything for 2.

2. type the following in your power shell window:

./fastboot flash boot boot.img

3. hit enter and

4. reboot to system (yes it has to be setup again since your data got wipede) and install Magisk manager after setting up your system

Congrats, your system is now rooted with Magisk!

[Google Pixel 4a 5G Guides, News, & Discussion] Voodoojonny:
That´s really strange! I have exactly the same console output... And it works for me.

Might it be possilbe that you use another rom build? I used the November -b build.

Maybe you can first update to the last os and then retry flashing my boot.img.

About BL-Warning. I have the same... And I dont´t know how to remove it. We would need to manipulate the bl, what I would not do...! Just ignore it!

For me, it also didn't work with your pre-patched boot.img (also on latest November update). Had to download the factory image and patch it myself to make it work.

My advice would be:

- ensure you got the factory image from developer.google.com corresponding to your buildnumber

- ensure you are using canary magisk manager (which is the only version as of today supporting redfin and bramble)

I'm trying to install Magisk, but I need a custom recovery. I can't figure out how to install one. TWRP app keeps force-closing when I try to install it, and there's no Pixel 4a 5G listed in devices in the TWRP website. I also can't find anything from ClockworkMod.
[Google Pixel 4a 5G Guides, News, & Discussion] Voodoojonny:
Hey, there ist no custom recovery available yet, becouse this phone is brandnew! There will be TWRP and other recoveries in the future, until then, we need to be creative. One way is extracting and patching the boot.img and reflash it via fastboot. How to do that is described in OP!

I got Magisk working. However, I cannot pass safetynet. I tried the props workaround mentioned in the 4a guide, but it still does not work.
[Google Pixel 4a 5G Guides, News, & Discussion] lmt1979:
Have you tried hiding the apps in Magisk? Do you want safetynet for a specific app that won't launch/complains about being rooted? Try MagiskHide in Magisk Manager if you haven't. Exclude those apps to hide root from them.
[Google Pixel 4a 5G Guides, News, & Discussion] WhiteAsIce:
Yep, I have those options on, but I still cannot pass Safetynet. I'm trying to get Google Pay to work. I've seen others say they got Google Pay to work by passing Safetynet/hiding root.
[Google Pixel 4a 5G Guides, News, & Discussion] GoldElocks:
If you haven't already try following this guide for passing safetynet on the 4a. You'll need the magisk props config module. This worked for my 4a and should work for the 4a 5g as well but mine doesn't arrive until later this week so haven't tried it yet.

[Google Pixel 4a 5G Guides, News, & Discussion] VerneVerne:
From my perspective, the best bet is to extract the boot from the monthly zip and just patch it yourself via magisk

Edit: oops, didn't see that it was not allowed to flash bootb
[Google Pixel 4a 5G Guides, News, & Discussion] lmt1979:
You have to flash the appropriate boot.img for your build that you're currently running. Pull down the shade all the way or go into Settings, About Phone, and get the build number (it will look like 11.0.0 (RD1A.201105.003.C1, Nov 2020) or 11.0.0 (RD1A.200810.022.A4, Oct 2020). Download that build from https://developers.google.com/android/images

Take the boot.img from the factory image you downloaded ( you need to extract it from the zip file) and put it on your phone. Patch it with magisk manager, then transfer it back to your computer to fastboot flash it. Make sure your adb, drivers, platform tools is all updated.

I got the phone on the 18th and had similar issues. Bunch of links and stuff on this post:
