[Q] Headphones correctly detected only first time after boot, not detected after that

I am experiencing headphones detection problem with my Xperia Z1. Headphones are correctly detected first time after reboot. If I try to plug them in after that phone doesn't detect them any more (external speaker is used even after I've plugged them in).
I contacted Sony support and they suggested it might be Smart connect. I cleared it's cache. Didn't help. I disabled/removed it. Didn't help either. I downgraded to an older ROM (don't remember if it was 4.2 or 4.3) and it worked as expected. Then I downloaded fresh .ftf of latest rom. Same problem re-appeared. Tried with Kit Slim custom ROM (based on 4.4) and experienced same problem.
It is obviously a SW problem. Is there any app which would allow me to manually direct sound to either destination? I have SSH server running on my phone. Is there any way to do this via shell? Any API call that I could utilize? I have no experience with Android dev but I am SW engineer and I think I could implement a simple app like this if someone would point me in the right direction.
Thanks!

it's definitely something with smart connect. had the same issue some days ago...... unistalled smart connects updates and installed them again -> works!

Tried that already. Didn't help
I contacted Sony support again and they suggested to try PC Companion's repair feature. What will that do? How that relates to the fact I'm running a rooted custom kernel?
Thank you!

hm try to flash .157 with flashtool. after that flash trinity kernel via flashtool and fastboot -> should work like charm dont forger to save your data before that I did the same and it worked for me

Where could I download that?

Android m charging slow

I flashed android 6.0 onto my nexus 6 and now its charging very slow. Charging was working fine on the rom i had previously. Everything should be stock except for my unlocked bootloader. Anyone else have this problem or know of any solutions?
Thanks

This has happened to me before, but I am rooted. I am currently rooted on 6.0, and I go into the "Kernal Auditor" app, and go to menu -> battery -> usb fast charge. I enable this option along with apply on boot, always fixes the issue. Currently I'm on 6.0 with hellsgod latest kernal for M.

yes same problem here, just upgraded OTA android 6.0 and my nexus 6 charges 40% in about 5h (with qualcomm fast charger or 2A charger)

Samsung Galaxy Note 5. Can't downgrade.

I downgraded to Lollipop from Marshmallow a few months back, and everything worked fine. After I downgraded though, I forgot to switch off auto update! and my phone automatically put Marshmallow back on. Now a few months down the line (and a few Marshmallow updates) when I downgrade to Lollipop via Odin, the phone will simply not detect my SIM card. I should point out that the only reason I want Lollipop back on my phone is that it works with my VW car Sat nav via rSAP connection, after the phone is rooted of course. Marshmallow will not connect even after rooting.
I thought it would be a breeze to just get rid of Marshmallow, go back to Lollipop, connect via rSAP and all would be rosie... no such luck! If anyone could help, it would be much appreciated. My hunch is that Samsung have done something with their latest update on Marshmallow to prevent downgrading, and rSAP connections!

supersu pro latest update killed my radio, now bricked.

Today I received a notification from supersu pro that I needed an update. After it installed it requested a restart. After restart, there was no connection to cell service nor could I turn the radio on in network settings nor were there any settings registered. I was however able to connect using WiFi from my home computer. I was running stock rom with twrp-recovery and OS h81120o for t-mobile. I tried restoring backups by twrp with no radio/network function. I installed
twrp-3.0.2-0-h811.img
android_device_lge_h811-android-5.1.zip
G4-H811-MM-20i-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Rooted in this order with nothing different working in network connection and radio off. I finally installed LG-H81120i-Flashable.COMPLETE.zip and it said installed successful yet when restarted the phone bricked. No power on, nothing. I received than same notice for my rooted Samsung galaxy tab 4 8.1 and declined it and am still running fine there. Any thoughts?

Hey,
I was in the exact same boat and almost gave up!
Got my LG back from repair and I rooted it then made a back up, everything was working fine. Flashed a new ROM and updated SuperSU, was not able to get a signal or mobile connection after that. IMEI Number was now NULL. I tried factory reset but still nothing can get the network signal back. Even restoring back to my back up did not work.
I read that if you flashed the LG-H81120i-Flashable.COMPLETE.zip you will brick so I avoided that. I finally found the solution and maybe this will work for you.
Download LG UP and your kdz file (H81120o_00_0613.kdz was mine) on your pc.
Set phone into Download mode by pressing volume up and connect to PC.
Open LG UP and load the KDZ path file and run. Phone should reboot and come back. My signal came back after this.
I hope this method works for you.
Best of luck!

S10 /Lineage os 18.1/AA Issues connecting to Car

Hi All,
Im have a S10 running Linux4's unofficial Lineage os 18.1 and I cannot seem to get the AA to connect to the car (Mazda 2021) .
The app runs on the phone, but when plugged in the infotainment system says it cannot connect to android auto.
Ive tried a bunch of different roms, all have the same outcome, i've tried the downgrade to 6.3 (Android Auto 6.3.611314) but that still produces the same error.
Ive installed magisk to run AA AIO toolbox, but that crashes once you click the I understand button (it gets SU) .
Is there anything im missing? Where can I see the error log?
If I go back to stock AA starts working again, but I lose lineage which would suck.
