[YU Yuphoria] Sin3.14:
i went to the service centre after a touch problem showed up on my phone and they told a software update is available and my phone was loaded with Cyanogen OS 12.0. But since it did not have any rooting capabilities, i went ahead and looked up some tutorials but could not find one and therefore ended up using king root. But now after some time i've realised that my phone has lost its signal strength, first sim (being of jio) almost never receives signal and though my second sim (airtel) shows signal strength, the person on the other side is not able to hear my voice(only some cracks and disturbance). The mic is working fine as i tested it on sound recorder.

So, i want to know is it a software problem that can be solved at home or i'll have to go to service center(which i would like to avoid as it's far away from my home)

Hi mastah...

Anyone can porting a Android Froyo / GingerBread OS to my zenfone 6? instock zenfone 6 just upgradeable to 5.0. i want to downgrade it coz i think newer version of Android , just for Newer Device. if i upgrade to newer OS, my phone must be lag. right or not??
[Android Q&A, Help & Troubleshooting] MigoMujahid:
No, if the stock update is for your device, then it's compatible with it, because the company released it for you, any android phone is upgradable but the phone's company just remove support of its old devices.

[LG G5 Questions & Answers] Xamineh:
Hi,

I recently bought a LG G5 SE and I would like to ask you owners about cases.

I found some nice cases at Amazon UK but they don't mention that it would fit the SE version.

Do you guys know if a G5 case would fit a G5 SE?

Asking this because according to the phones specs, the SE is slightly thinner then the normal G5 (0.5mm).

Anyway, anybody here with a G5 SE using a G5 case?

Thanks!
[LG G5 Questions & Answers] Trevinho:
LG5 and LG5 SE are completely equal in size and case.... So yeah. Just go for them.
[LG G5 Questions & Answers] Xamineh:
Almost.

G5: 149.40 x 73.90 x

G5 SE: 149.40 x 73.90 x

I wonder if this 0.5 mm makes a difference when using the case.

Downloaded android n-ify module from exposed ..

Or any other way to have it ?

[P8lite Q&A, Help & Troubleshooting] crashpoum99:
I've tried using N-ify too. Turns out that these kind of things don't work on EMUI. I have seen a list of xPosed modules that don't work on the P8 Lite here on xda, can't find the thread though. As a workaround you could use the "material status bar" but it is just a cover for the stock one (with plenty of bugs). Other than that, the only way to modify the status bar would actually be installing a custom rom, when one gets availiable.

Does anyone have the Joying digital amp for the new VW units?

I ordered mine couple days ago.

https://youtu.be/hifENMDt5nk
[Android Head-Units] nk33:
I have this unit and after 2 months i have the issue with the LCD not showing up. Joying have told me it is a known issue and sent me a video of how to solder the main board.

Can anyone confirm this works before i pay someone to do it for me?

the alternative is to send it back to Joying for a refund - but the issue with this is that i actually still want a full Android head unit...and sending it back will not solve this problem....

thanks in advance
[Android Head-Units] frankienones:
This partly work:

On Joying FW 20170314 , modified audio_policy.conf

USB DAC : ASUS Xonar U3

Exellent sound , but not able to control volume from Head Unit
[Android Head-Units] AssassinsLament:
I'm willing to bet it's the same issue, Joying's physical volume knob/buttons only control their physical outputs, and not the android system's volume. The Android system's volume can be controlled by apps or keyboards/remotes, and it does control the dac's volume... problem is, Joying's software changes the Android system volume back to max after a few seconds.

frankienones, I suggest you try a keyboard or remote that has volume up and volume down keys, and see if it controls your dac's volume.
[Android Head-Units] gustden:
I just installed Viper4android and it is working. I have noticed that when I use the google voice command, it no longer lowers the volume of the music player. The same thing when the system reads a text message. The message gets read, but the music volume doesn't lower.

Is anyone else having this issue? Is there a workaround?

- edit - Problem resolved, it was unrelated to Viper...
[Android Head-Units] kampfschachtel:
the volume control issue sounds to me like a problem of who is controling the USB stream: Joying or the DAC? it looks to me like both do which causes the issue.

Would be interessting or the way to go to try an asynchrone USB DAC as it will take over the control and the timing of the USB stream.

Another source for the issue can be that some DAC's are using analog volume controls but some are using digital volume control. Difference is the analog volume controlled DAC the volume control happens after the DAC has transfered digital to analog, means the analog output signal is modified in the level but digital input is continous and steady in level. The digital volume controlled DACsreduces the level of the digital input signal means the level/volume control is done

before

the DAC and the DAC's analog section is just amplifing the input with a fixed output factor.

To me it looks like the USB-DAC first takes over the volume in a digital way (volume gets reduced by reducing the digital input signal), volume gets effectivly reduced and then joying unit takes over the control and delivers a continous digital signal (as it has analog volume control) and the input of the digital volume controlled DAC gets the full input level which gives you the max. volume output level.

Looks like an asynchrone DAC (which takes over the control of timing and USB stream permanently) with analog volume control would be the way to go/solution.

Normally the small form factor and cheaper DACs are using digital volume control as cheaper to realize (reduces number of parts needed) and therefor also smaller. More expensive ones use analog volume control as you need a real preamp for this and it doesn't reduce the dynamic range of the digital input signal as digital volume control does.

Would try myself an asychron USB-DAC but I am in hospital now for next 3 till 5 weeks...
[Android Head-Units] frankienones:
Yeah, i will do that. I have ordered a bluetooth remote, which are supposed to do this -and will see how it works. I don't have anything else for the moment ...

I really want this to work, with the crystal clear output from the dac :cool:
[Android Head-Units] AssassinsLament:
Well I am pretty new to these Android head units, and so my knowledge is very limited. But what seems to be happening is the MCU is acting sort of like a DAC. What I mean by that is that there is no internal "speaker" like how a tablet would have built in speakers. So android basically streams through the MCU, and thus you control the volume level on the MCU via the volume knob/buttons, which has no interactions with Android's system at all. And because of that, they did not program anything in their software to change the volume on android's system when you turn the knobs. Also, that's probably why they programmed it to always max Android's sound level, so the MCU can get the max input from android's stream.

Again, if you can find where in Joying's software they are monitoring the sound levels of Android and are maxing it, then you could just modify the Joying software to stop doing that, and you can use a remote or an app that can change the volume (since Joying's knob/buttons doesn't do it, and even their Speaker Icon on the notification bar doesn't do it, as those only control the MCU's volume). Then the DAC will work fine. I know this because I disabled the software that maxes out the Android system volume, and the U202 worked great... but sadly, that same software is what streams the sound to the MCU, and does a lot of other things unseen and sadly, again, the knob does not work to change the volume.

Obviously, the best solution would be to try to get Joying's knob and buttons to do it as it's more convenient.
[Android Head-Units] AssassinsLament:
In the mean time, you can try an app that changes android's system volume like this one:

https://play.google.com/store/apps/details?id=hr.podlanica

You'll probably see that it works but something is forcing android's system volume to max after you change the volume levels.
[Android Head-Units] kampfschachtel:
My unit has no hardware knobs, only touchscreen buttons which means software behind: https://www.carjoying.com/eu-wareho...android-5-1-1-lollipop-bluetooth-4-0-aud.html

you are right, the joying seems to work like a DAC with digital volume control as it max. the level of the input before their internal DAC and USB port gets excatly that stream out to the DAC. So you would need a dac with analog volume control means the joying max the input to the DAC, the digital info is transfered into analog and only then at the end the preamp of the DAC is controling the volume that leave the DAC. That the joying is not able to oversteer the external USB-DAC you need an asynchron one who takes over the control. This dac should be controlable by an app which you can give the master volume of the touchbuttons on the screen.

If you have an digital volume controlled DAC as the UAC 202, the DAC gets always the full volume as it is controlled by the joying. But if the input level doesn't matter because the analog preamp afterwards controls it, the joying can do what it wants.

What happens if you use/connect your system to the headphone output of the Behringer which you can control by the volume button of the build in headphone preamp? If you can adjust the volume with this volume button, then you can be quite sure you need an analog volume controlled asynchron DAC as he does exactly the same but the volume can be controlled via software. this would be a suitable one: https://hifimediy.com/U2-DAC

or the gladen DSP 4to6 could be used, then you can integrate digital and analog outputs and volume control via App or the hardware remote volume knob

KODI - Volume control

Hi, an interesting note :

I was not aware of it (never touched it) , but KODI has a volume slider control.

This does control the volume out from my external dac :) And it is not reset by Joying HU

Joying's volume control has no effect.

But when disconnecting the DAC , after setting a volume of , say 50% inside KODI, the volume from the head unit is 50% of the current setting of Joying's volume control (..still using KODI app)

..does this make any sense ?
[Android Head-Units] kampfschachtel:
yes it makes a lot sense. The Kodi app is able to take over the volume control of the DAC and Joying, if DAC is present it gets priority, if you unplug it Kodi uses this 50% as value for the volume setting for joying. I assume Kodi uses the standard AISO volume control which both units seam to work with.

This confirms that joying usb volume control is not recognized by the DAC so the joying "only recognizes" the output need to be delivered to internal DAC which triggers the joying control to max. volume due to Joying has a analog volume controlled DAC. With Kodi the joying unit knows a DAC is connected and disables the joying volume control.
[Android Head-Units] kampfschachtel:
Is there an app which replaces the 3-Band Equalizer to min 11Band, better 15 Band?

Means it works on the output of the joying doesn't matter if I use Spotify, FMRadio or Navi and not only inside a player app.
[Android Head-Units] AssassinsLament:
What Joying headunit model do you have? Might be the difference in models and their different Joying software. But that's good news for you since you don't have to worry about the volume automatically changing back to max.

The part about the 50% is I think when you set Android's volume to 50%, that basically is 50% of what Joying is expecting, which is max. I suppose if you change it back to 100% before or after you disconnect the dac, it should be back to normal?

EDIT:

Might even be that KODI has it's own way of processing the volume. Might be a good idea to try to change the volume in android with an app like the one I linked before.
[Android Head-Units] frankienones:
..thats right . If i leave KODI at 100% , the volume will be as normal , when the DAC is unplugged (Normal , as in Joying's control)

I have the version with 10.1" screen - no rotary buttons etc. This One
[Android Head-Units] AssassinsLament:
Well that rules out KODI having it's own volume processing since the volume does change system wide. So yeah, android's volume does effect Joying's final volume, which makes sense as to why they program their software to automatically set android's volume to max, at least on my unit. I have the JY-UL124N2, I'll have to check if they have the same firmware.

EDIT:

Same firmware. What version of the firmware are you on? The latest March 14th?
[Android Head-Units] AssassinsLament:
Ok, I just tested KODI and it seems they have their own volume processing. When I change the volume on KODI, the media that KODI plays certainly changes volume also, but when I look and play music outside of KODI, the volume is still max. Have you tried playing media with kodi closed?
[Android Head-Units] frankienones:
I only used the DAB+ radio App , and then the volume was back to max.. .

It is my finding as well.. that it will only work inside KODI . It will be useless , but interesting :)
[Android Head-Units] AssassinsLament:
Yeah, so my thoughts were correct... KODI has it's own built in volume processing.
[Android Head-Units] HVB83:
Ah thanks mate, does seem to make a lot of sense. I knew the hdd might be on the edge as far as power-supply goes, but assumed that as long as the drive is recognised it would be ok. Does appear that this is not the case. I'll try with a usb flash drive tonight and see if that changes the situation because it uses way less power than a hdd, or is the length of a (poor) cable alone enough to cause these kind of issues?

Good remark about the dormant mode, that might also be an area on which I might need to focus on next. But for now, I assume using an ssd will hopefully resolve my problems, since it did work ok before.
[Android Head-Units] kampfschachtel:
Yes cable length and quality plays a big factor here. The resistor value doubles each 50cm plus it rises exponentially with the current you draw over it in parallel..

The USB DAC and joying expects/designed for around 200-500mili ohm input. A mid quality 1m USB cable has around 400mOhm at 300mAmpre. Imagine what comes out with a poor quality, 2m length and 1-2Ampere....far out of the specs.

At mine it was the 1m poor quality cable and dormancy mode, since I got the 15cm mid quality USB cable and switched dormancy mode off no issues.
[Android Head-Units] HVB83:
I would be very interested in a modified DAC-script which outputs the radio and phone/bluetooth to RCA again also. Right now any outputs from the system go directly to DAC, but apparently the items mentioned are not handled through the Android-part of the unit but connected through an MCU-type of board before being output to the amplifier/RCA-connections.
[Android Head-Units] ztbishop:
*EDIT* - The two units below appeared to work, but for whatever reason they both now have constant pop / static.

I'd posted yesterday that they would work but now I'd advise against them.

- Sabrent USB to 2 X 3.5mm Audio Stereo Splitter ($5)

Sound Blaster Omni -DID NOT WORK. ($80) I really wanted it to, since it has a sub out, and volume knob.
[Android Head-Units] AssassinsLament:
a) No, as the audio routing is (most likely) done in the kernel, and thus we can not change it without the source.

-------------------------------------------

**EDIT**

I found that the Viper4Android directly from Google Playstore does work for my USB Audio Out. This is the one with 7K downloads and Asian characters on the description. It does not appear to be the same app that I downloaded here...slightly different interface.

-------------------------------------------

Will Viper4Android work with USB DAC? I've seen in other forums people doing it (not specifically on Joying). However I haven't gotten it to work yet.

I got the BEHRINGER U-CONTROL UCA202.

RCA out going to a pioneer compact amp in the glove box

Headphone out going to a separate subwoofer amp (will install an in-line volume knob in the dash)

*Installed the mod to control main volume with the Head Unit volume knob (working) - this will control the main and sub amps overall volume.

I will also run an RCA Out from the Head Unit to the DAC Input, so I can pass phone calls and Radio sound.

For $30 this device seemed like a no-brainer.

Main issue at this point is I cannot control the EQ.

Built in EQ won't work (didn't expect it to).

I've gone through Viper4Android install threads through all of the Joying threads and got it to ...sort of install. I still had to use a root explorer to find the pkg and 'install it'. However, it didn't seem to do anything after reboot. I've checked all options...tried setting every type of speaker (HU, USB, etc...) made no difference.

If this isn't known to work, I will try to find an in-line EQ to cut into the Dash Kit (I have to cut it up anyway since the Joying wouldn't fit the Double Din Scosche dash-kit properly).

-If anybody knows of a simple in-line EQ I'm open for suggestions. I'm not looking to spend hundreds more on a DSP at the moment...I honestly don't mess with EQs much but it would be nice to have.

Just tried resoldering my PA2030A swap for the third time and still getting no sound. Giving up on soldering for tonight, but I've started reading up on USB DACs in case I've irrevocably wrecked the traces for the internal DAC.

I'm still trying to confirm whether the radio or phone would still require the internal DAC or would a USB one be able to process all of the unit's sound. What are some of the remaining limitations of using a USB DAC if there are any? Is there a usbdac only mod for the newer releases of the firmware or is it just for 5.1?

I started reading the first few pages of this thread, but I'm frustrated and falling asleep so I apologize if these questions have been answered already.

[Android Head-Units] ztbishop:
I just installed a DAC on System 6 and a mod to let the volume knob control it. The phone and radio do not go through USB; they will still go through the internal amplifier. If you don't use FM radio, and if your amp really is shot, some phone carriers like verizon have apps to let you use any device as your phone through internet connection (which I think would go out USB) - only downside would be if you lose internet connectivity then you may need to use your actual phone instead.

I'm wondering if there might be some bluetooth audio app that lets you make phone calls through another android device using your phone. I cannot find one and don't think it exists.
[Android Head-Units] PsychoMcSatan:
There is an app and it's called Tablet Talk. In fact [MENTION=3076686]gustden[/MENTION] wrote up a guide on how to use it to enable voice dialing. What I still can't wrap my head around is whether Tablet Talk could possibly be used as a complete replacement for the stock dialer. It would then be using Android sound and should work through a USB DAC? Currently, it just routes the dialing requests to the stock dialer.

As for the radio, I found an app called SDR Touch which appears to be able to use a USB dongle to tune FM radio (and more?) so I'm starting to hope that I might be able restore full functionality even if I can't get the internal DAC working again.

Yeah, there are obvious paths on the bottom of the board, but there are some pins where no paths are visible. Must be multi-layers. I've already sent an email to Joying to see if they'd sell a replacement motherboard. I guess it's also possible I got a bad PA2030A.

Sorry for another noob question, but I just got my Behringer UAC202 in the mail and I was thinking of picking up a cheap car amp off of Kijiji and I'm not clear what type I should get to power my four stock speakers (no sub, at least not yet).

As this DAC has only has stereo output, how do I split to four speakers? I see it has optical out, but are there amps that would receive that?
