Did you take out the micro SD card as well? Do you get messages when the device crashes?
[T-Mobile Samsung Galaxy S 4] fmaster12:
Yup, I tried rebooting without my SD card as well, same problem occurs. And usually what happens is it'll boot up, but becomes unresponsive as soon as I touch it. It will then reboot by itself and go into a bootloop. In the rare occasion I am able to bypass my lock screen after booting, I get a com.process is not responding and my background is all black. This too will eventually freeze and enter a bootloop.

i am looking for a good stable daily driver and came across one that i think is gonna be a keeper for a while. but i am curious to see who likes what and for what reasons. Battery? Speed? Bloat? Style? i also think it would be cool if you added a link to the Roms thread so people can try out your favorite for themselves. i am currently flashing up the ladder to achieve the proper build that will allow me to flash the new rom without hiccups and will give my 2sense when i have had a chance to give it a throttling.

Right now I'm on [MENTION=1503720]tx_dbs_tx[/MENTION] 's "Ultimate Note 5 Hybrid'". An awsome Note 5 port. It's THEE new standard in Note 5 Ported roms. Go there and chat it up. Some very helpful users with inside knowledge about the rom.

It's. Here :

Tried them all and absolutely loving Sacs Note 5 Moar port. You can't get it on the forums - you have to pm Sac and he will invite you to his hangout.

Only negative on this rom is battery life. If you are one of the folks out in the wilderness with no power or just afraid or to lazy to plug your phone in - this might not be the best rom for you. Though some folks do get good battery life. Some do not.

I'm on rooted OK1, nothing fancy, no custom ROM, just a couple Xposed modules for battery life, Nova Launcher and a few simple tweaks, otherwise fully stock.
[Sprint  Galaxy Note 4 General] tx_dbs_tx:
That underground moar port isn't something that I would recommend to anybody. It is not able to be publically released here at xda-developers.com because permission was denied to port that rom for very good reasons. Secondly that rom was not built correctly and it has major problems and will most certainly overheat and damage your cpu and/or battery. I do not recommend anyone to flash or run that underground rom. There's a good reason why it is not a publically released rom and why it has yet to be finished and done correctly. He would have to copy my work to resolve his issues if he hasn't already. Ofcourse i have seen him state that he is going to rebase his N5 ports with my rom. Waiting for that o be posted so we can finally get rid of this type of behavior once and for all. Too bad he can't build his own rom from scratch like I did.

So no this is not a rom that should be recommended to the OP. Just my opinion and my advice to those who are unaware of these things. People deserve to know.

[Sprint Samsung Galaxy Note5] laie1472:
You could try powering off your note5 and then plugging it into your pc with it powered off. Then boot into recovery and your pc should give you a prompt that it will try to install the correct drivers. Not a 100% sure it will work but you can try it. Also what drivers did you download and install for your note 5 to be recognized by your pc? You could try theese if you haven't fixed your issue yet. Hope this helps.

[Sprint Samsung Galaxy Note5] HUSKERS:
Had same issue and would also not fast charge. MTP not being recognised and had to have Sprint replace it. Charge was $75 because I had no insurance but a complaint to Sprint that Samsung would not fix issue that was replicated by Sprint store allowed me to get a $75 credit on account, so a wash. Worth a shot.

---------- Post added at 11:36 PM ---------- Previous post was at 11:32 PM ----------

Also, FYI i did send it back to Samsung to repair BUT they do not have the actual issue available in their issues dropdown area so they just put issue as "would not recognized charger" Well when repair received device they tested, saw it started to charge and just send it back out without fixing anything. Very frustrating but all worked out with device replacement.
[Android Head-Units] sithcommander66:
Hello, Im new here. Have always used an iphone. Only ever had a smasung s3 for a few months and was presently surprised by how solid android has become.

Anyways, I am looking to put a double din HU that runs android in my car.

I have ordered and used the Joying headunit 4.4.4 and it was great except for a few points:

1. Doesnt read address book from phone via bluetooth, needs to be imported.

2. SOUND QUALITY.... is not great. Not unbearable but barely passable in my opinion. And that is with the bc06 bluetooth. Running mp3s from the HU directly was slightly better/clearer. But I mostly stream audio from my phone, so I was not happy with the audio quality. I played around with the EQ and got it as good as I could and was slightly dissatisfied. Very boarderline.

3, UI is difficult to use in clutch situations. Would be nice if there was an app\overlay that would give me just a couple of high priority apps on screen within reach. Im sure this is easily done, didnt spend much time trying to get it to work.

I see that PUMPKIN is coming out with a unit that uses the parrot Bluetooth card that should bring the bluetooth audio quality up to max. Leaving the preamp to be the weakest link.

How are you guys dealing with this? And do you think I should spring for the pumpkin that will give me good BT quality? Also, are there any good EQ apps I could use to fine tune the audio to get maximize audio quality?

I really like the headunits that run android and cant live without all those other features but the audio quality really needs to be addressed.

Here is what Ive used:

(cant post links yet)

JY-UQ130 Joying

Here is what I want to buy now:

11-RQ0259E-US-A Pumpkin - only available on their site for now, will be on amazon soon.

Let me know what you think and if rooting it would help me get the most out out of the pre amp module.

I also have an external 2200 watt amp that I have in my car, so maybe I could tune that? IDK...

Thanks
[Android Head-Units] Den9696:
glad i read this before buying the joying unit for my VW. looking for something with decent audio quality as well.
[Android Head-Units] Hisma:
none exist at the moment, sadly. the only way to deal with the poor sound quality of these HUs is to buy an external DSP & use that to process your sound instead. minidsp 2x4 is the cheapest option to accomplish this ($100).
[Android Head-Units] thekoter:
Hi,

I've just found MXTRON HU with dual ST sound processors.

Here is the website : www mxtron com
[Android Head-Units] halloj:
Still only dual core 8GB and only 4.2.2. The question is what do they mean with dual sound processors? Because the standard KLD has

dual sound processors too, sometimes with the brand ST.

---------- Post added at 11:18 AM ---------- Previous post was at 11:15 AM ----------

[/COLOR]

I've bought that unit and the sound quality is not okay even if they are using parrot. The two microphones

are still in parallel with lower sound quality. It's equal to my modified KLD. I.e. no improvement.
[Android Head-Units] tangoman99:
What's the sound quality like if you use an external DSP? Is it as good as a good car audio system, or is it just smoothing over the cracks?
[Android Head-Units] Smokey619:
Yes the sound quality is not great, the rca pre outs are super weak, i tested mine the pumpkin from amazon and the voltage is on like .8 VAC rca i bought a line driver and that got my voltage up to 4.2 VAC rca which now my bass hits like before.
[Android Head-Units] Hisma:
Personally I still feel like something is missing. It is absolutely better, but a DSP can't generate frequencies the sources doesn't produce. So I still would prefer a HU from someone known to produce high quality audio. But the android units have all the features I want so I just go with it.
[Android Head-Units] tangoman99:
Darn it - I wish I'd seen the stuff on here before buying it.

I really notice the frequency cut off - it's like listening to a really badly chopped low bitrate mp3.
[Android Head-Units] Hisma:
yep, huge disappointment to say the least. with the amount of time and energy I've put into my system, I'm still not completely happy w/ the results. I'm still learning how to tweak it, so I am certain I can get it to sound better, but I guarantee a high quality audio HU would not need near this much TLC.

Most probably don't notice missing frequencies, but a critical listener would. I own some high quality headphones, so I know what my music is supposed to sound like, and its just not there.

Think I'm going to add a line driver to my signal chain next, as the pre-outs are a measly 1V (and the DSP chops that signal up even more). Hope that does the trick.
[Android Head-Units] tangoman99:
Any point in doing 7floor's mod and using an external dsp or are they achieving the same end?
[Android Head-Units] Hisma:
theoretically flattening the EQ should remove all custom audio processing, making 7floor's audio mod useless if you use an external DSP. However, b/c of how suspect these units handle audio, I wouldn't even be surprised if a supposedly flat EQ on a non-modded unit isn't really flat.

But yes, they are achieving the same end. Of course the internal DSP, even w/ the audio mod, would not be near as effective or give you as much control as an external DSP.
[Android Head-Units] CadillacMike:
most of the time I read about sound problems, it is due to using Bluetooth. Is the sound still bad if you use Google Play on the actual head unit?
[Android Head-Units] misslovanu:
That's my question as well.
[Android Head-Units] dazza007:
It has taken me soundproofing, 3 sets of frontstage speakers (currently on my third set), an amplifier and a good subwoofer to improve sound quality in my car and a 7floor mod with these units. There is always something to improve in the sound in a car and I am leaning towards a decent headunit now. The radio tuner and sound quality on these units are its' weaknesses it is such shame as the OS is great.

I just read that with Android Lollipop it is possible to connect an external DAC via USB:

http://www.phonearena.com/news/Android-5.0-Lollipop-supports-USB-DAC-audio-devices-we-go-ears-on_id66399

Would that be an option to have better audio quality? Is there a USB-DAC which would be suitable for a car?

[Android Head-Units] lowridincrew,:
Do these devices have the same sound card? I need some of the apk of one to control sub vol on the Joying
[Android Head-Units] nixfu:
I think that sound quality playing mp3's on these units is excellent.

On my Joying unit, while the bluetooth is not the best in the world, if you are playing mp3's off an SD with MediaMonkey, or PowerAmp it is VERY good.
[Android Head-Units] nomailing:
Do you have it connected directly to the speakers via the ISO connector or using an external amp via the RCA outputs?

I am still confused when people here talk about the bad audio quality if they are talking only about the too low pre-amp outputs. If I connect it directly to the speakers I should not have that problem, or am I wrong?
[Android Head-Units] Hisma:
Yeah Sq is okay if your not using pre outs and decent amp and speakers. If you are, you'll expect more. The 7floor mod proves how poorly the mcu handles the dsp on these units.
[Android Head-Units] BCK_Phoenix:
Any further results regarding issues found with these android HU?

[Android Head-Units] skezza:
What do you mean the pre-outs? RCA Outs?
[Android Head-Units] Grungi:
I'm very confused.

Is there any difference in sound quality from MTCB to MTCD or in the Joying Sofia Headunit?

Is it better (audio quality) to mod the MTCB according to 7floor or just buy a new sofia or MTCD Headunit?

Then there is this guys that Solder a Pioneer pa2030a amp chip to the board do they still have the equalizer problem?

Thanks for any info
[Android Head-Units] MONGO_abaday:
When I went from my stock installed HU (Skoda VW) to a MTCC I certainly felt that the audio was lacking somewhat in comparison to the stock unit. I'm no audiophile but just couldn't quite put my finger on what was lacking. Probably mainly in the Low to Mid freqs. So dealt with it best I could using a custom audio profile but still wasn't quite enough.

I recently went from that MTCC to Sofia and would say yes there is an improvement in audio there but haven't had the stock VW Skoda HU installed for ages so wouldn't be able to tell you if the sofia unit is on par with it or not.
[Android Head-Units] R0ttenB4ndit:
Hopefully the newer units do sound better..
[Android Head-Units] Grungi:
Right now, i'm thinking about improving the audio quality with buying the Kenwood DNX516DABS Head Unit.

Alternative could be my MTCB with an external Amp like Pioneer GM-D1004.

not sure now.

The Kenwood thing would just work without hazzle... an external Amp is like space waste for me and for soldering a better Mosfet i could not find any information for MTCB.

I didn't use any of the Android Features like Internet/App Store/rooting/Wifi anyways. I just would like to use the BackupCamera and listen to Music FILES. The Dashcam/CarRecorder Functionality was so bad, i'm using now a Viofo Dashcam instead.

Any Ideas?

Greetings and Thanks
[Android Head-Units] Grungi:
Update.

I will order now the "Behringer UCA202" USB DAC and if i get that running with my MTCB RK3188 Unit (i try to update to Android 5.1), then i will buy the Pioneer GM-D1004.

This will take time, i will update about this in a view weeks...

Is there any way to have an Equalizer running?

Where would the EQ be, after the USB DAC, before the Amp?

Or is there an USB DAC with Android controllable EQ?
[Android Head-Units] stealth_b2:
I bought Joying for my Toyota and used it together Hertz HCP4 (for door speakers), Hertz HCP-1D (Earthquake 12" swallow mount sub). The speakers are: Hertz HSK-165XL for front with tweeters included in the package, but for rear doors only mid-bass units (same model) were used.

Result was sad. Sound is muddy and goes worse if you play loudness and bass/treble settings.

The solution was to buy Pioneer DEH-80PRS (yes, reference series). Now I still use this Joying, but only for Navigation and watching movies. 80PRS has best DAC and mic for auto-calibration. In future I will upgrade this joying, but only for navigation and multimedia purposes. Music listening through this cheap crappy hardware is not a option. In my setup, 80PRS is used as "car receiver", joying is connected to it like low quality signal source.

PS. The FM tuner integrated into this joying is worst radio I have seen. Choppy sound and unreliable reception if car is moving. I used full size quarter wave FM whip antenna to be sure, that the reason is not antenna and it was not. The tuner itself sucks. The problem is not "joying" specific, the platform itself is "huifei" type and it really does not matter, which label is used for branding. If you care about quality, stay away of this crap. Buy one good reference series HU and add some android tablet for visual needs. Today many new tablets has bright screen and they are cheap, you can upgrade after every year or two (90USD), but this HuiFei type units displays are very cheap and picture is not bright enough for a sunny day.
[Android Head-Units] Grungi:
I have now Android 5.1.1 running... from this Forum. I guess its malayks rom. not sure.

The USB DAC muted the music playing when plugged in, but i could hear no output on the DAC-Out

Then I fiddled with the audio_policy.conf and the developer settings in android...

Now it doesnt have any effect anymore when i plug in the USB DAC.

I tried with Behringer 202 and the Zhilai Audio H1.

Don't know what to do.... any Suggestions?

Can i see somewhere if Android has found the USB Audio Device?
[Android Head-Units] Primal74:
LOC?

To improve the sound quality and to run amps wouldn't it be simpler to just add a line out converter? Using the speaker wires from the HU as input and converting it to low level RCA? Wouldn't this be better for the newer Android based models with sound quality improvements? Particularly when the RCA oit out voltage is so low.
[Android Head-Units] fantaxp7:
I used to have an android head unit like 5 years ago. Ditched it immediately because of the audio quality.

However looking at how far things have come they are very tempting again.

I also came across something interesting today, the smarty trend sound processor. I wonder if this will fix audio quality before sending to an external amplifier?
[Android Head-Units] esounds:
The chipsets - whether AllWinner, Rockchip, or other - come as chip SETS. Meaning, there is a DSP in the system already. The audio quality is great if you are relying on the unit's audio itself.

HOWEVER, once you plug the (typically sub-2A) RCAs into an amp or even an external DSP you will notice just how horrible these units sound. The audio is painful at higher volumes - very high-pitched and unrefined. Somewhere in the translation from chipset DSP to the audio cables there is a poor transition.

One of these days a vendor is going to realize that if they would just engineer a head unit where the handoff is optical right out of the head unit (like Clarion, Alpine, and Kenwood now offer) you can plug directly into an after-market high-end DSP or some amps that now have optical inputs. You can therefore play hi-res audio files right off your head unit and enjoy (theoretically at least) "better than traditional Japanese head units" quality.

Then just convince SiriusXM, DTS for HD Radio, and beef up the GUI for these capabilities and you should be able to sell more than 10K units/yr. :D

---------- Post added at 12:42 AM ---------- Previous post was at 12:34 AM ----------

How do you connect to it? It appears to be USB, but then the optical says "input" not output. So you would be relying on the smarty trend DSP which I am guessing is no Burr-Brown level DSP.
[Android Head-Units] fantaxp7:
Good question. I am thinking now that I am looking at it closer it may just be a device to connect an external amp to the digital audio of most German cars. I was hoping maybe it connected directly to the head units bypassing and analog connections....maybe it can do that?
[Android Head-Units] Hisma:
It's actually possible to use these units with USB audio. My dsp accepts spdif, so I bought a fairly expensive ($99) USB to spdif adapter and ran coax back to my dsp. My dsp has a volume control knob that I ran to my front console, and neutron player has a USB direct driver for my USB adapter.

You'd think it would be the perfect setup, as I was getting sound directly out of the unit and bypassing the analog conversion, but it still sounded terrible.

I have resorted to actually using high level output from my rear speaker wires, and I found this gave the best quality sound. Still not impressive, but at least it is no longer garbage. I think two issues are that there must be some sort of noise isolation issues on the board, that affects any low voltage signal coming out of these units. Made worse by the output voltage being extremely low. Using high level output you mitigate this by having a naturally higher signal to noise ratio.

Overall though these units are junk for any audiophile. I still run mine however bc I accepted that sounding "good enough" with the high level output and keeping a stock look and all my controls is worth it. I've sunk too much money already to sink even more in for less functionality. Knowing what I know now though, I would have bought cheaper gear so my expectations wouldn't be so high. Lesson learned.
[Android Head-Units] les_garten:
I am building an audio setup in my car and you've got me scared here. I thought the Atoto A6 Pro had a Toshiba chip in it and could produce good audio. Has anything changed since you last posted here? The amp I am looking at using is the JL VX1000/5i with a really nice built in DSP.
[Android Head-Units] electricmonk3000:
I have been trying to make the decision between an android head unit and one of the name brand ones for a few weeks now. I have tried reading whats on here, watching youtube reviews and looking at review sites. All I can say is that the information is either not there or way too in depth for me ha ha. All I want to know is that as of this date, are there any double din android head units with good quality preout voltage. I already have my setup in the car so am going to be using the amps I have in the boot. I want to be able to mirror my android phone to the head unit or at least have GPS built into the head unit. I need front rear and sub preouts. I do not need or want CD/DVD. If no android unit is available I will just go back to the name brands for now. Can anyone shed some light for me? Thank you in advance :)
