[Android Head-Units] edit:
Out of the box the EQ is really bad on all of the Chinese units. I've changed quite a lot of models in the past 5 years and all of them were pretty bad.

For that we have Viper4Android, that is an AMAZING piece of software EQ (probably more like an sound processor).

The unit has a separate Sub output control but I haven't tested it... don't have a sub in my car.

BUT

If you are an audiophile these units are not for you. As an audiophile you must have pretty high standards and I am afraid the sound quality of the cheap Chinese units will let you down. Don't get me wrong, for an average user like me, streaming most of the music at 128/256/320 kbps and has medium quality speakers the sound is quite good (with Viper4Android enabled) but It's an only 300$ piece of hardware.... you simply can't ask for more.

Yes you can mod them and maybe change the amp mosfet but you will not get to have audiophile quality out of it. If you get an good external USB DAC and pair it with an real sound processor and maybe with an good amplifier... maybe then you can get closer to a real audiophile solution.

Again, if you are the kind of guy that his cheapest set of headphones are in the 1000$ range or your speakers at home are 3000$ worth.... look somewhere else.

Change the amp chip with a Pioneer chip and the unit is bad ass :)
[Android Head-Units] megapimp:
Thank you for this answer... Maybe I chose the wrong wording. I do love quality audio but im not anal about sound. as long as i can adjust the mids highs and lows and for it to sound great not cheap hallow sounding. im used to 7 to 10 bands will i be able to get a true adjustment out of these with 7 band software? Ive seen the Pioneer upgrade just now but thats only for power output. Im currently wanting to install in my escalade with the stock bose amplified speakers. I will be adding 2 sundown 8 inch subwoofers in a tuned box and want to have full media from the unit. spotify music apps loaded music and vids
[Android Head-Units] bogdi1988:
Pioneer chip upgrade is not just for power but also sound quality.
[Android Head-Units] edit:
Your best bet with these units, if you don't want to buy additional hardware (sound processor, an external am with a fancy EQ) is to root them and install Viper4Android (that requires root). Viper gives you the ability to have a pretty good EQ and many other features to tune the sound to your liking. Like I said in my previous post the onboard 3 way EQ is maybe decent for some but I found it pretty poor. Viper was the only piece of software that could bring back the good bass that I was having from the original headunit of my Ford that was made by Sony (this time) and it was made specifically to drive the speakers to their best. Viper has feature that limit the bass not to overwhelm the mids , very usefull.

The DAC in the Joying units is decent and probably closer to good (for my ears and my car speakers) but don't expect audiophile quality out of it by any means. If I had to grade the amp+dac from 1 to 10 I would chose an 6 maybe 6.50.... 7 it's a stretch but maybe with many Viper teaks....

Your Bose sound system is definitely more revealing in therms of sound quality than what speakers put Ford in my car so after installing the Joying you might be a bit disappointing that I've gave the HU an 7 :)

Sound quality is a delicate matter, what is good for some is bad for others.

The cheapest hardware sound improvement would be to change the amp chip (into the Pioneer one), I haven't done it for 2 reasons so I can't comment much on how big the sound quality changes...First I NEED to know that I am buying an genuine chip and not an fake one, ebay is full of them and you simply can't detect a fake, or test it somehow after you received it. The original from Pioneer is around 40$ and the ebay ones are from 2.50$ to 15$ that doesn't inspire me confidence.... and second, even if I have the soldering skills I don't have the equipment needed and finding someone with the proper skills and tools it's a bit complicated.

If you want to control the sub from this unit I read that it's not an good option but you have to look into it:

Read here, these people wanted more sound quality from this unit and they started to mod it : https://xdaforums.com/android-auto/android-head-units/joying-2gb-sofia-headunits-common-t3577217
[Android Head-Units] megapimp:
very good thank you so much for the detailed response. I am more the able to swap the amp chip as i build stand alone ecus for vehicles. I am just turned off that these units wouldnt put good items inside. What headunit may come out in the future that everyone is keeping their eyes on? I see other units with 7 to 10 band EQ settings on them that are cheaper. are those fake eq settings or just the same ole bs?
[Android Head-Units] edit:
These are cheap units for the average Joe. They need to sell many so the low price point is the key...

When it comes to the EQ all I can say is that my previous unit (Witson) had out of the box a 7 band EQ that was absolutely rubbish... Unusable... Major crap. Viper saved the day. So even if the hardware is decent/good, they are dragging it down with poor software.

Joying with the Sofia implementation it's the best unit that I have used so far.... With each year new units pop up but not all are decent and just a few get a good support from xda.
[Android Head-Units] zerozoneice:
funny thing is, some units that have more than 3 band EQ sliders (like 7 or 10), do bundle them in 3s anyway...you move one and the ones left&right of it move as well :) go figure....

i guess if one's not happy with the default output, there are 3 choices right now: replace amp, viper mod and 7floor hardware mod+custom EQ sw. That's pretty much the pinnacle of what can be achieved, sound-wise, on chinese units atm. Unless someone really skilled tears the thing apart and re-does pretty much everything down the audio-chain.

....4th option being always of course: stay away from chinese android HUs :P and get something else....like a Pioneer AVIC-series. U do the math and pro/cons on that..
[Google Pixel XL Guides, News, & Discussion] jdpro22:
After having issues with my camera and USB port, I have to get a replacement device from Verizon. I was pissed to have to do this because I used depixel8 to unlock my phone and the new one would be on 7.1.1 and locked. I booted up the device without the Sim card, just on the off chance I was on 7.1. It was on 7.1.1 and the oem unlock option was grayed out. After putting in my Verizon Sim, the option is now ungrayed and lets me flip it freely. Am I just lucky or what? I got the device through asurion and they said I would for sure get a Verizon variant
[Google Pixel XL Guides, News, & Discussion] awakenedwithin:
Yep, lucky ducky.
[Google Pixel XL Guides, News, & Discussion] jdpro22:
The weird thing is, the sim card is what flipped it from being grayed out to not. I threw a big fit with both Google and Verizon about not being able to use my phone for its designed purpose. What are the chances they changed it for me?
[Google Pixel XL Guides, News, & Discussion] fiffan86:
Probably slim to none, you got lucky like did the first time. the first return I got from Asurion was unlockable on 7.1.1, my replacement a month later due to a bad battery, was locked, but it was a BRAND NEW phone the second time, the first come in a Asurion box and was obviously a refurb, the second came in the retail box like if I just bought it from Verizon.
[Google Pixel XL Guides, News, & Discussion] enviouz:
It's more the luck of the draw. I'm on my 4th pixel XL. One brand new one and 3 from warranty. #1 was locked and had Samsung memory. #2 unlocked with Toshiba memory. #3 locked with Samsung memory. #4 which is my current one is again unlocked again with Toshiba memory. Seems it's only the 32gb versions too. So they are definitely out there. I have yet to see this happen with the 128. I'm gonna take a stab in the dark and say your current unlockable one has Toshiba memory. Just a hunch. Seems to be the common denominator.
[Google Pixel XL Guides, News, & Discussion] bobby janow:
It's not.
[Google Pixel XL Guides, News, & Discussion] jdpro22:
Idk what this comment is referencing. What's not?
[Google Pixel XL Guides, News, & Discussion] bobby janow:
The post immediately above the comment.
[Google Pixel XL Guides, News, & Discussion] jdpro22:
So it's not luck of the draw? Or it's not only 32gb models? Or it's not because of Toshiba/Samsung memory?

See how just saying "it's not" with no context is a little confusing?
[Google Pixel XL Guides, News, & Discussion] enviouz:
I made a poll AWHILE ago trying to get somebody to show me a full unlocked Verizon variant (not depixeled) with Samsung memory. I have yet to see one. If anyone can show me one that's fine. I'm just saying so far every single fully unlocked Verizon pixel XL that I've seen or read about has had Toshiba memory. I'm not saying thats the reason they are unlockable...I'm saying that is the pattern I've seen. Ive been waiting to see one but have yet to.

---------- Post added at 01:12 PM ---------- Previous post was at 01:09 PM ----------

Jdpro how much and what brand does it say your memory is on the bootloader?
[Google Pixel XL Guides, News, & Discussion] bobby janow:
If you search there was a memory thread a month or so ago and it has been dis proven. You'd have to search for it though. But think about your theory for a sec. If that were the case don't you think JCase would have said that at the outset? So basically what you are saying is that if you have Toshiba memory you can unlock the bootloader whereas if you have Samsung memory you cannot? Well anyway, as you were a part of that thread, here is the post I was referring to. https://xdaforums.com/showpost.php?p=71459372&postcount=53

Just one further thing. Are you saying that *all* Google Pixels have Toshiba memory? Simply because they are all unlockable. I still think it's the IMEI but no one has confirmed.
[Google Pixel XL Guides, News, & Discussion] tttuning:
Same thing happened to me
[Google Pixel XL Guides, News, & Discussion] enviouz:
I do remember that thread. I was speaking strictly in terms of Verizon 32gb models. From my personal experience and that I have read. To my best recollection I haven't seen a Verizon/32/Samsung that was unlocked without using depixel. And I haven't seen a Verizon/32/Toshiba that needed depixel to unlock. These have all been verified as Verizon variants by cid. I also never meant to imply that it was because of the memory. Just that the pattern so far seems to be if you have a verizon/32/Toshiba it's garenteed to be unlockable...I'd actually like for that theory to be disproven. I'd also genuinely like to see a Verizon/32/Samsung that's unlockable as easily as the play store version. That's all I was saying. I have no experience with the 128...there seems to be no common ground with those.
[Google Pixel XL Guides, News, & Discussion] bobby janow:
I see. So you're basing it on empirical evidence which is all well and good and certainly interesting if it does fit a pattern. However, that really doesn't go to the method that Verizon uses to lock the bootloader option. Since the 128 does not fall in line with the locking/memory scenario then I can't see that the observation is anything other than that. Don't get me wrong, I find it intriguing but not of any great value for those that want to unlock the bl. Unless I'm missing something, which has been know to happen now and again. ;)

As you witnessed in that thread there doesn't seem to be any rhyme or reason that is obvious. It was thought the CID, the Sim, IMEI etc. None of which panned out. I'm not looking to unlock my bootloader so this is all academic to me. But I certainly am curious.
[Google Pixel XL Guides, News, & Discussion] enviouz:
This all definitely true. And that is all it is...just theory based on observation. And it doesn't really help to unlock the bootloader at all. But where it does/could come into play is if your looking to purchase say a used on on eBay. It's probable that you could find a cheap priced Verizon version. And say the seller doesn't realize the value of an unlockable one. Because they aren't part of the scene or for whatever reason. Then say because of the price it's a better deal than a play version IF it's unlockable. That's when you ask them to check memory manufacturer. Of course this would only work on 32gb versions. And there is always a slim chance that this cycle could be broken. I also understand that this is a very specific scenario so the theory has little usefulness. But still nonetheless it's does have it's place. And is of some worth. Until a fully locked verizon 32 Toshiba is reported.

Most people would never think this far into it. So I'm sure it might sound crazy. And I'll admit that it kinda does. I had to retype it like 3x because it sounded way too out there. Lol.

You did it why? If there was nothing wrong with the device other than you didn't like the locked bootloader you told them that and they replaced it?

[T-Mobile Samsung Galaxy S7 Questions & Answers] harshal.rio91:
Does anyone have a issue where the mobile sometimes performs some operations delayed. Like for example:

1. When I click check for updates in settings menu the menu doesn't popup instantly it pops up after like 30 min.

2. Cannot send messages same issue messages are sent after 30 min.

3. Same thing with Google Play updates, they get downloaded and get stuck on installing(they do get installed after some time like 30-45 min)

I already tried resetting the OS and it worked good for a few days and same issue popped up.

Should I replace the device?

[Tilt, TyTN II, MDA Vario III General] bluemamba:
Hi.

I don't seem to last a day without recharging my battery (either by USB or Outlet).

I have some useful programs but I'm afraid to use them sometimes because my phone wont last the day.

On a regular day, without extreme program usage (WiFi, GPS, games etc), just regular phone calls (GSM not 3G), my battery power lasts maybe 18 hours.

If i used 1/4 of my installed programs moderetely, my battery power lasts for about 10-12 hours.

I would like your professional advise to better by battery life.

1. Would changing my ROM to a better modified one solve my issue?

2. Is there a backround process (that is not detected my my task manager) working that I should know about?

3. Are there any tweaks (non registry) that I can do to better the life?

4. Are there any registry fixes that can be done to better the life?

5. Do third party cabs (SPB etc.) drain the battery life even if they are idle?

6. Does letting my battery fully drain and then fully charging it over and over really help the overall battery life?

FYI: I have the OEM ROM, my phone had never been Hard reseted before

I have tried all sorts of things, but I cannot manage to get my phone to last more than a day.

I would really appreciate your advise.

Thanks.

P.S please dont tell me that you people go 2-3 days without charging (that would hurt my feelings :) )
[Tilt, TyTN II, MDA Vario III General] Eraser85:
my kaiser lasts about 10 hours if heavily used, I mean 3G internet always on, browsing with opera mini all while listening to MP3s..

With normal usage and 3G coverage (but classic talks, not video ones) it last al least 2 days..

that's strange
[Tilt, TyTN II, MDA Vario III General] boojingyou:
Hi,

i managed to have good power after alot of research and tweaks on this forum.

-disable 3g service

-make sure no application auto-enable wifi, make sure its off.

-make sure device is set lock all buttons

on normal days with just afew calls and very little surfing, i my battery life is the same as other non-pda phones!

[Tilt, TyTN II, MDA Vario III General] bluemamba:
Would updating my RADIO help?
[Tilt, TyTN II, MDA Vario III General] Maarten_0031:
Default ROM sucks. The registry is setup completely ineffecient (like all M$ software) so eats capacity and battery.

Best thing to do is check the 'Kaiser upgrading' thread and compare the radio version you have with what's posted there and see if you could improver performance. I'm still on the original radio that it cam with, but trying multiple Rom's dramatically improved battery life. That and speed and performance. Their is much to gain, my friend.

I advise you read the articles about CID and SIM unlocking before attemting to flash anything.
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
Upgrade your radio to 1.27.12.17/32, turn off 3G and flash some clean ROM (like Q-Mobile - see in my signature :))

My phone can survive now more than 3 days on normal usage. Before it could live 2-3 days max.
[Tilt, TyTN II, MDA Vario III General] MickyMax:
Maybe can you enable alimentation tweaks with KaiserTweak to begin ?
[Tilt, TyTN II, MDA Vario III General] bluemamba:
I dont think and fixes of those kind will do anything

I think what Maarten_0031 and gabriel31337 say is the obly way. I will reseach what kinda ROM best fits my need and let u know

Lets see how it goes without 3G and with the tweaks I did today.

[Tilt, TyTN II, MDA Vario III General] smartyP:
it can't be stated enough how quickly your battery will die if you have your mailboxes checking for new mail 'as they come in' or 'every 5 minutes', etc. if you have important emails your expecting then turn it to those settings, but if you don't care if you get your mail only every hour then go that route - it makes a big difference in the battery life.. also make sure you have the disconnect option in kaiser tweak set on - i have mine set at disconnect after 2 minutes.. and finally, if you can get away with using edge then have your phone always set to edge and only set to 3g for web surfing - pulling down your text based email in edge and not 3g is usually a pretty negligible difference.

on a side note, i bought a 3000mAH battery for about $70.. it improves the battery life a decent amount, but the reality is is that if you use the GPS for 2-3 hours without having it plugged in while using the GPS then you can always expect the battery to be dead by the end of the day (or sooner).. if your going to use it as a GPS then have it plugged in..
