Hi, I hava an Elfin and today I started to have a problem with the incall audio in the speaker and olso in the earpiece, but when I use the speaker for music or any other sound it works OK, I change ROM, Radio and same problem. Any ideas?:(:(:(

thanks in advance!!!!
[Touch GSM General] Imyman:
You've mentioned problem but haven't specified which kind? Choppy sound, broken coverage, no sound at all. Whats it like? Remove the casing around the speaker and try cleaning it. Dust etc accumulates there pretty quickly. It sounds more like a hardware problem to me....I doubt it would have to do anything with the phone software etc.
[Touch GSM General] tony7351:
thanks for your reply, it sounds like sparks, but the rare thing it only happens during a call, because when I use the speaker for music or other sounds is OK and when use the speaker for a phone call the sparks sound come again!! :(

My friend in china sent me a new NOVA 10 SE , I put my sim card and there is no single at all (Emergency calls only)

the IMEI number is there and correct , shipping the phone back to china is no option, is there a fix for this or is this a hardware issure?
[General Questions and Answers] xXx yYy:
Check your SIM card. Make sure that your SIM card is properly inserted into your phone. Remove the SIM card and reinsert it, making sure that it is fully seated in the slot. You can also try cleaning the SIM card contacts with a soft cloth.

Make sure that your phone is in a cellular coverage area. Check the signal strength indicator on your phone. If it is showing no signal or only one bar, then you are not in a cellular coverage area. Try moving to a different location to see if you can get a signal.

Reset your network settings. This will restore your phone's network settings to their defaults. To reset your network settings, go to Settings > System > Reset > Reset network settings.

If you have tried all of the above and you are still not getting any signal, then you may need to contact your carrier. They may be able to help you troubleshoot the issue or send you a replacement SIM card.

Welcome to the project that started a revolution.

A complete home experience on the cover screen.

Compatible with all 1" or larger cover screens.​

This project began as a replacement for the Samsung Health widget that allowed launching apps. It has since grown into a full overlay that works alongside the stock launcher on multiple devices, inspiring the release of other launchers and even a Good Lock widget along the way.

TooUI adds cover screen support for apps, full notifications, widgets, quick toggles, voice launch, custom screen timeout, animated wallpapers, and more without recording how you choose to use it. Even our bug reports are filtered with your privacy in mind.

Compatible with Samsung Health and lock screens.

Fingerprint unlock must be used with a secure lock.

Notice: Due to an Android 13 bug, touch is not passed to the stock launcher when TooUI is minimized. Double tap the SamSprung icon to temporarily disable the launcher until the screen is turned off.

Known issues (Tested only on SM-G386W so far):

MAJOR BUG: None of the REBOOT OPTIONS works. Pull out the battery and power on normally or use adb reboot from command line.

UPDATE: REBOOT SYSTEM seems to work right after ROM install but will not for subsequent boot into twrp

Not clear how good are BACK UP and RESTORE functions - Use twrp2.8.1 from https://androidfilehost.com/?fid=24052804347847251 to back up and restore your stock ROM.

Data encryption (FBE, FDE) - Excluded during compilation from for the moment - FIXED

NEW: If after flashing a ROM your internal storage content is hidden:

Reboot into twrp

Go to Advanced, then Fix Contexts and reboot to finish (pull out the battery or ADB Reboot)

How to install:

Warning again:

None of the REBOOT OPTIONS works. Pull out the battery and power on normally or use adb reboot from command line. Using this might bricked your ROM.

[Samsung Galaxy Core.] greggit1986:
I am not sure if I will ever succeed! It took me almost a year to get to this point and have been trying over the last few months to improve it without luck. But who kmows? I almost gave up at some point and then Khabit on twrp telegram put me back on the right path.

I think the key is to be able to build the kernel from source. I am focusing on lineageos 17.1 aand 18.1 for now and I will eventually return to it.
[Samsung Galaxy Core.] Lost-Entrepreneur439:
Not working properly on my G386W. Attempting to install zips from the SD card causes TWRP to reboot, only ADB sideload works. It appears CPU architecture also isn't being detected (MindTheGApps says my CPU architecture is " ", literally nothing)
[Samsung Galaxy Core.] greggit1986:
This is strange. I never had any issues installing zips from sd card since the first day I successfully compiled this twrp. It has been my only method to install Roms since. Did you try a different card or format it ?

I know another person using this twrp at the moment but his device is SM-G386T1. I will asking him if he has experienced similar issues.

For MindtheGapps, I think the issue is with the ROM. I also have not been able to install it even with lineage recovery since my very first lineageos 16 and 18 builds. I will eventually get bact to it to confirm.
[Samsung Galaxy Core.] Lost-Entrepreneur439:
I did try formatting my card and I tried a different card, but no, I was still unable to install ROMs from my SD card. I don't think it was an issue with MindTheGApps, it installed fine with Lineage Recovery, and OpenGApps gave me an error too (although I don't remember what it was)
[Samsung Galaxy Core.] greggit1986:
Yeah. The issue is neither with MindtheGapps nor twrp. I was able to install it along one of very first successfull lineageos16 build. Something is broken in the new lineageos but I cannot quite figure out what it is.
[Samsung Galaxy Core.] greggit1986:
I was wrong! There was an issue with twrp. It looks like it is fixed now! Ckeck download section for the new build.
[Samsung Galaxy Core.] greggit1986:
Not sure if you are replying to the correct thread but there was an actual issue with twrp here and it has already been fixed.
[Samsung Galaxy Core.] greggit1986:
Did you even try using it?
[Samsung Galaxy Core.] Lost-Entrepreneur439:
fairly sure these are just AI responses
[Samsung Galaxy Core.] greggit1986:
Yeah! I was suspecting something like that.
[Samsung Galaxy Core.] The Smith:
@greggit1986 Thanks for your work in keeping this device alive.

I tried the crDroidAndroid-10.0. It works mostly, but there is a problem with the Gapps Play Store not able to install anything, complaining I need to free up space, which I have enough.

Looking at this thread, it seems the TWRP recovery is the culprit and that 3.7.0_12.0 fixes the issue. Is it just a matter of recompiling for our device?

Regards,

Smith
[Samsung Galaxy Core.] greggit1986:
Thanks for the feedback. I will recompile this weekend to see if we can get a newer twrp revision. But I am not very optimistic since the only twrp branch I can successfully compile is not longer getting (or is barely getting any) source updates.
[Samsung Galaxy Core.] greggit1986:
Also, what gapps flavour did you use? mindthegapps, opengapps or you tried both?
[Samsung Galaxy Core.] The Smith:
Yes, smallest package for both.
[Samsung Galaxy Core.] greggit1986:
I recompiled twrp this morning and as I was suspecting, I am still getting 3.7.0_9.0. I fear we would have to be able to compile with a newer branch than 5.1 if we want to upgrade. All my past attempts resulted in twrp bootloops. I can't unfortunately diagnose since the prebuilt kernel didn't include logging or I simply don't know how to make it work. Same story when I build the kernel myself.
[Samsung Galaxy Core.] The Smith:
Aww, that's too bad. :(
[General Questions and Answers] Fehuvosu:
Hello.

I noticed that A-GPS does NOT work in many android firmware, the NetGuard firewall does not even fix XTRA http requests, so the problem lies either in the gps.conf settings or in the android firmware source code.

If you clearly understand how A-GPS works and how to check it, then I will be grateful if you answer this question with a short answer:

1) Android smartphone model

2) android version

3) name and/or firmware version

4) Are there ephemeris for the entire group of GPS satellites?

5) Are there any XTRA http requests to NetGuard in the "GPS daemon" system application?

Example:

1) Xiaomi redmi note 7

2) android 10

3) miui 12.5.1.0 Global Stable

4) no ephemeris

5) no http requests

I am testing A-GPS through the GPSTest program:

Spoiler content hidden.

http xtra requests are monitored through the NetGuard firewall (root is NOT required):

Spoiler content hidden.

To understand if A-GPS works, I do this:

1) turn off the Internet, GPS

2) I clear A-GPS data in GPSTest (menu - "Clear additional data")

3) reboot the smartphone

4) turn on the Internet, then GPS

5) I look NetGuard for http requests (system application "GPS daemon")

6) run GPSTest, click on the menu "Enter PSDS data"

7) I look NetGuard for http requests (system application "GPS daemon")

8) I look at GPSTest for the presence of AE flags (almanacs and ephemeris) for the entire group of satellites

Information about almanacs and ephemeris under the spoiler:

Spoiler content hidden.

If A-GPS works on your firmware, then after rebooting and turning on GPS

and/or after clicking "Enter PSDS data" you have:

1) an https request to XTRA servers appears in NetGuard

2) almanacs and ephemeris appear in the GPSTest program ("AE" flags)

means A-GPS is working.

If there are only almanacs (flag A) for all GPS satellites, then we consider that A-GPS does not work.

Screenshots:

link - screen after http xtra request (a-gps). All GPS satellites have an E flag (ephemeris)

link - screen after http xtra request (a-gps). All GPS satellites have an E flag (ephemeris) and an A flag (Almanacs). As I understand it, this is the ideal work of A-GPS. When the entire group of satellites has the flag A + E.

link - screen in the NetGuard firewall with XTRA and NTP requests from the "GPS daemon" system application

link - video showing the appearance of Ephemeris after running GPStest. (cleaning and entering PSDS data into GPStest does not work, but ephemeris downloaded after turning on GPS)

This information applies only to the GPS navigation system (not GLONASS, not Galileo, not BeiDou, etc.).

Thanks to everyone who will respond.
[General Questions and Answers] xXx yYy:
Most modern smartphones support A-GPS (Assisted GPS) for example these:

Samsung Gallaxy S series

Google Pixel 6 series

OnePlus 10 ProXiaomi Mi 12 Pro

Oppo Find X5 Pro

Vivo X80 Pro

Realme GT 2 Pro

Asus ROG Phone

Motorola Edge 30 Pro

To check if A-GPS is enabled on your Android device, you can follow these steps:

Open the Settings app.

Tap on Location.

Under Location, make sure that the Use location switch is turned on.

Tap on Mode or Manage location services.

Under Google Location Accuracy, look for the Improve Location Accuracy switch. If the switch is turned on, then A-GPS is enabled.

If the switch is turned off, then A-GPS is not enabled. To enable A-GPS, tap on the switch to turn it on.

BTW:

A-GPS is supported by Android since the Gingerbread release in 2010. In later versions of Android, A-GPS support has been improved. . However, the implementation of A-GPS can vary from device to device.
[General Questions and Answers] Fehuvosu:
You are not right. Enabling the "Google Location Accuracy" option does not enable A-GPS.

This option improves the accuracy of the location due to the Google database, which contains wi-fi routers, bluetooth devices, cell towers. And the location is already attached to them. As a result, a huge database is created, where being near a given wi-fi access point and cell tower means that you are at a certain GPS coordinate. That's how it works.

A-GPS is when an operating system or program downloads a file from the Internet that contains almanacs and ephemeris of GPS satellites, resulting in improved location accuracy.
[General Questions and Answers] elcrys:
Interesting topic. I was never able to download ephemeris data on my phone:

1) Xiaomi Mi A1

2) 13

3) lineage-20.0-20231101

4) No ephemeris data.

5) There was a request by "GPS" process do download the data, but only almanac was downloaded. I used AFWall+ to track this.

I followed your guide but the best I was able to achieve was an "A" flag in GPSTest for all satellites. I have also Nexus 7 2013 with an older LineageOS 14 and it downloaded ephemeris data without any problem. I know there are differences in gps.conf so I tried to use the same *.conf in my phone, but the result was the same. I tried also other configurations from the Internet without success. I read somewhere that GPS configuration is partially baked in the Qualcomm GPS modem so it's hard to say if and how it can be changed.

I attached my gps.conf for a reference. I don't remember how AGPS worked in stock ROM.
[General Questions and Answers] Oswald Boelcke:
Maybe off-topic to the exact question in this thread but I'm only concerned about privacy in the use of A-GPS. For this reason I use this Magisk module:

GitHub - PlqnK/magisk-supl-replacer: Magisk module to replace the SUPL provider in gps.conf

Magisk module to replace the SUPL provider in gps.conf - PlqnK/magisk-supl-replacer

github.com

My Samsung SM-G955F picks the satellites up extremely fast and calculates the position very accurate considering the non-military mode of GPS. Very satisfied.
[General Questions and Answers] Fehuvosu:
The problem I have is that the NetGuard firewall doesn't even record http requests to any server at all. Therefore, no matter what SUPL or XTRA server I install, there is no HTTP request.
[General Questions and Answers] nacos:
I use a simple script in AdGuard (paid) to block all native A-GPS requests on port 7275. Before implementing the script - quite surprisingly, I should add - all my A-GPS requests, on all my Samsung phones, would go through Amazon, not Google (SUPL). See attached screenshot and, if curious, use WhoIs to search the blocked (red) TCP/IP requests. The script is simple and it works 100%. It might even work in NetGuard. Obviously you'd need to change the port number, if your A-GPS requests are being sent through a different port.

/.*:7275/$network

AdGuard, (alongside AdGuard VPN) on the other hand, it's worth every penny. Highly recommended!

View attachment 6039424

SUPL aside however, unless you're using one of the privacy hardcore ROMs (GrapheneOS, DivestOS, or CalyxOS), your phone leaks your SIM ID (and who knows what else) to Google every time you connect to a Wi-Fi. AdGuard, apparently can strip off these personal identifiers if the Network Manager (tethering) system files are being redirected through AdGuard. I cannot see exactly what the stripped code looks like however, the files are shown as being modified every time a Google Network Stack requests gets through.

Hi all,

I added new AID's to my ASOP build following the steps over here (https://source.android.com/docs/core/permissions/filesystem#using-file-system-capabilities).

And it worked well, the only thing that I haven't been able to do is to add specific capabilities to those newly added AID.

I was wondering if there is a way to define each AID capabilities on compile time? this way each process running with the AID as it UID will be granted the specific capabilities defined for the UID.

I tried looking on google , the android documentation and on the forum but I haven't been able to find anything.

Check if it shows as SPRD U2S DIAG. If the device is not detected then please disassemble the phone to repair dead boot.

Short the two test points I have marked in red color in the picture and connect the device to your computer.

If now it shows as SPRD U2S DIAG then install the Spreadtrum/Unisoc drivers. Make sure to disable Driver Signature Verification first on your Windows machine to avoid driver errors.
