Disabling GNSS duty cycle - Huawei Mate 20 Pro Questions & Answers

Hi, I need to turn of the duty cycling of the GNSS (GPS) chip on my mate 20 pro. I was under the impression that it should be an option in the developer settings in Android Pie, as it is in other phones, but there is no such option for Mate 20 Pro.
Does anyone know why and better yet how to solve it? I must turn off the duty cycling for my research project. Thanks!

hey do you find the way to turn off?

Huawei P30 Pro EMUI 9.1
Hello did you find a solution to your problem? I am an owner of the Huawei P30 Pro with the latest release of EMUI 9.1. I can’t find how to disable the duty circle on GNSS raw data measurement (there is no option under the android developer settings on my Huawei Device). In some smartphones duty circle can automatically disabled when you call android GNSS raw data API. Does the Huawei supports this feature or we can not disable duty circle on Huawei smartphones at all? Thanking you in advance.

hello I communicated with the engineer of huawei only to know the EMUI doesnt support disabling the duty cycle. Are you trying to use the carrier-phase for RTK or PPP ?

Duty Cycle
Yes I am trying to develop an app using the kernel of the RTKLIB open source library for PPP and RTK purposes. I have already tested this with XIAOMI MI8. I am also interesting in buying the new Xiaomi Mi 9 with Qualcomm 855 in build gps chip. Did you ever test the Xiaomi Mi phones? I also have already test the mate 20 pro for dual frequency carrier phase measurement. In order to implement the L5 frequency on this model, you have to update to EMUI 9.1. But this issue with duty cycle is critical so I can not support this model also with the P30 Pro.

Root Call Blocker

Hello!
I used the Google phones until the Nexus 5. Now I went to exchange and the price to import to Brazil is absurd. I bought the Xiaomi AI M1.
I used Call Master (https://play.google.com/store/apps/details?id=fahrbot.apps.blacklist) as a call blocker and SMS but this application is not working on Xiaomi MI A1 with Anrdroid 8.0 ( Oreo).
I also can not make SuperSU work on the Xiaomi MI A1.
I've always used SuperSU on my smartphones.
Now I'm using Magisk. I do not know if Call Master is not working because I'm using Magisk for root. The Call Master developer only uses SuperSU. But this developer does not support (even though I'm paying for the application).
Can someone tell me a root call and SMS blocking application that works on the Xiaomi MI A1 with Android 8.0?
Thank you.

Android Pie & Encryption

Hi guys,
I currently have an Honor 8 with Android 8.0, in I have some issues with encryption.
You may know that Huawei phones does not respect completely the Android expectations in terms of encryption, which lead that some application like Intune (Microsoft) sees the phone as "not encrypt", and reject the creation of professional profile.
This features was OK for me on Android 7.x, but not anymore on Android 8.0. It also seems to impact Mate 10, P20, Honor 9, 10...
As I plan to buy a Mate 10 pro (hope good offers for Black Friday...), I wanted to know if those who have tested the beta of Android 9 on this phone can check the security parameters, and see if the encryption option is available or not, and if some of you succeedeed to enrol within Intune.
Hope my question is clear enough.
Thanks for your feedback

Honor 8X Gallery without Discover tab

Just found out my new honor 8x' gallery app do not have Discover tab, just photo & album. Seems like other huawei or honor phone have it? Any clue? EMUI 8.2.
Same here: I have never seen on my phone.
Inviato dal mio Honor 8x utilizzando Tapatalk
Finding
Seems that this is common among honor 8x user.
I did search on Chinese huawei forum, below are the finding:
1. Some say it have discover feature, just need time to generate the discover photo, with some criteria, including with huawei ID, sync to cloud, turn on geotag.
This mean some user actually get Discover features.
2. There is one post suggest to re-login huawei ID, reboot the phone, clear data & cache of gallery.
There is no clue the person who post this had solved this issue or just general suggestion.
3. One interesting post mention currently this feature open to some models only.
I have no idea how this guy have this information and maybe he mean some of the honor 8x models (honor 8x have few different models name) only have it. Hopefully this feature could roll out to all honor 8x in the future.

Enable unofficial ASHA Hearing Aids support to android 10 devices

Hi,
I'm looking a way to enable AHSA protocol to device that are on official Android 10 with official updates from manufacturer
Last year Google has annouced Android 10 will support Hearing Aids with ASHA Protocol, specification are open, but i think integration to Android 10 phone is not mandatory
I have a Oneplus 5 and recently Android 10 has been released out to this device by OnePlus
Sadly, i can't stream music directly to my hearing aids.
As far i know Pixel 3 and Samsung devices are compatible, i've tested with a Samsung S10e and this is working great.
Google provide a technical specification for ASHA Protocol, i dont know if this for dev or something ? https://source.android.com/devices/bluetooth/asha
So what i've found so far when playing around with my OnePlus 5 :
- I've decompilled the bluetooth apk from my OnePlus 5 phone and there some files related to hearing aids in the bluetooth apk bluetooth.app/sources/com/android/bluetooth/hearingaid
- Found a file text in /System/etc/bluetooth/
in bt_profile.conf at the end of the file
Code:
#Hearing Aid profile and its configurable features
# hearing_aid_support with default value false
[HEARING_AID]
[B]hearing_aid_support = false[/B]
I've rooted my device with Magisk and i've tried to change to "true" and reboot but changes are reverted back maybe because /system is read-only ?
i want to know if someone can dump the file from a pixel 3 or a Samsung S10/S20 device and share here ?
@johnstinks
Only to have mentioned it:
Android's hearing-aid setting is stored in Android's settings.db under System: It's either 0 or 1.
https://android.googlesource.com/pl...e/+/master/core/res/res/values/config.xml#131
Try setting this to true using an overlay?
sorry .., i've no idea how to do, i've never compiled a rom or anthing
my message is a bottle sent to the sea, sharing idea to enable / force the support for hearing aids for phones on Android 10.
I would also be interested in a way to activate this in custom roms. I'm waiting until it's more widely available before I get my next phone
Bumping up this thread. My dad just received his new hearing aid, and initially the audiologist told us direct streaming is only supported on iPhone, but upon closer checking, I found that selected Android phone models are also supported. Sadly, his Huawei P30 Pro is not on the list.
I tried pairing his hearing aids with my sister's Samsung S10 and it worked like a charm, it even has the hearing aid icon beside the bluetooth device. Although the P30 Pro supports Bluetooth 5 and has Android 10, it doesn't recognise the hearing aid.
Hoping that some experts here can share if it's as simple as rooting and enabling the setting, or is there something in the bluetooth APK that needs rework in order for the hearing aid function to work?
Hello,
I need this feature really, too.
Does someone got a way to enable it on a rooted smartphone?
Best regards
bump !
any idea, maybe with magisk module we can enable the feature ?
Best Regards.
Trying to find the solution for my son with his Xiaomi Black Shark 3, anyway so far I didnt find any ASHA solution, so I am going to check Phonak hearing aid which should support BT connection via A2DP and HFP, so it could be temoporary workaround without ASHA support on phone (seems to just on few Samsung and Google models at the moment). Anyway ASHA is final solution of course, all advices would be really appriciated.
On my OnePlus 5 i tried a custom rom called "ArrowOS" this rom does have a experimental flag "settings_bluetooth_hearing_aid" i enabled this flag and i have hearing aids support !
Now i have to found what actually does this flag when i enable it. ( what file is modified)
here some link from the android source code where the flag is found:
if we understand how to enable the feature we can maybe create a magisk module that enable ASHA for any phone on Android 10-11

Hi I just came across this post as I also want to enable ASHA on an 5t. Does it still work for you with ArrowOS?
know how to enable this feature???
I'm adding my name to the list of folks that want to do this as well (I have an Umidigi A9, but it sounds like the same basic issue applies).

This would be really great.
Following. Thix is really interesting
As ASHA is mainly enabled on the software side (given your hardware matches the requirements), does this mean that custom ROMs on Android >= 10 supports hearing aids streaming ?
As soon as I received my Widex Moment headset, I have been using a hearing aid since I was a child, I feel very sad living in a world where technology was for everyone, adding walls for the sake of money, back to top, I also use the Redmi Note 9 Pro which uses Android 10 and BLE but doesn't pair, I tried a lot of things. Why should I have to buy a new phone instead of fixing it, 2 years have passed and they have not fix it or update about this. I have spoken with Widex & Xiaomi support, the 1st one told me that will add more mobile devices to his list, the 2nd one seems not to be so interested since he does not reply to my email. Once again I feel so bad, I hope someone will can give a solution to that.
I will try Service and Feedback from my phone also

In the same boat here, with same phone. I am about to get cochlear implant activated.
The problem with P30Pro afaik is that Huawei have disabled unlocking of our phones meaning we will never get custom roms or install 'hacks' which is pretty ****.
One would think after all these years of ASHA protocol spec being available it would be implemented more, but no. Outside Pixel, Samsung and Apple its pretty dead in the water and I don't know why since it appears to be just editing one or two lines of code to activate it.
At this stage we can only petition to Huawei to enable this feature.
