No backup camera settings on px6 dasaita - MTCD Android Head Units Q&A

Finally got the backup camera installed and bummed out with the image quality from what I understand on majority of Android head units there is a way to adjust the brightness contrast and quality settings of the backup camera. It appears that the only option is in the factory settings that only lowers the brightness. I need to adjust the exposure and saturation does anybody know if there is any way to adjust this on a dasaita unit running vivid 11

OMG I know how to increase video recording FPS to 25!!

Trust me this works, I just found this out right now and had to tell you guys. All you do is lower the brightness in the settings. You'll notice right away that as you keep lowering the brightness the framerate starts increasing. Just jitter your hand while you lower brightness.
I also strongly suggest you lower the contrast(to 1 or 2) in the camera settings to brighten up shadows.
Great. The brightness itself doesn't seem to suffer as it compensates the brightness somehow and the fps is nicceee
D: Brilliant! Well, at least that lessens my dissapointment in my TP xD
This really works. Thank you man.
I just tested it out by recording 2 videos. One at normal brightness, and one with 0 brightness.
The zero brigthness is CLEARLY more fluid. HTC you suck for not giving us good frame rates out of the box. Also lowering the brightness level doesn't seem to actually make the video much darker.
What!!? I can't believe this works!! It's awesome!
Now we just need a program to change the backlight up and down when the camera app is open/closed!
What is the framerate if you dont do this?
I made those adjustments and it makes the shadows appear VERY grainy.
Are you talking about fps in preview mode or does it actually change the fps when recording video?
Thanks.
Cool, I'll try it as soon as I get home.
do you mean i have to put brightnes to 9 o to the lower possible value (-1.5)?
TNX
is there a chance to do that in the xperia x1?
My recordings are still 18fps after doing this, but the video is much smoother when recording in low light areas (which is pretty much anywhere in-doors).

[Q] camera ISO

Is it possible to change the default value of my device's camera ISO level to 100?
when it is on 0 the pictures look very noisy and even when the camera lens is covered and all I see is black there are a lot of noisy in the picture. The only thing that fix that is to change the ISO level to 100

Android Head Units Sound Control Software

Question about the software on these things. Do they have control for Crossovers for the Front, Rear and Sub? Does the EQ settings stick to the Front, Rear and Sub? Is anyone able to tap into the sound control through a app or something like that?

They have a nice EQ but no crossover setting. You also cant control the sub out put its on at full out put all the time. Had to put in a bass knob to fix that.
Going deeper than the built in audio and I found out some professional audio cards also work and Creative brand hardware. Check this out

Interesting ill have to check it out.. Let me know how you hook your up if you do this.
Something new about able to use some software?
Since the units also have a subwoofer out ?
Please delete
Did someone contact manufacturer and asked for an option to adjust sub separately?
Just buy a decent dsp and you'll be able to adjust all settings that you like. I'm happy they also provide the full range signal on all outputs, if necessary without any adjustments, leaving me to do the tuning myself.

Got any suggestions?
Something like this: http://mosconi-system.it/product/gladen-dsp-4to6/ or this: https://www.minidsp.com/products/minidsp-in-a-box/c-dsp-6x8
Although I must admit I don't know the Minidsp myself. Between the two I would say Mosconi is the benchmark, costing a lot but delivering almost uncomprimised quality, whereas the Minidsp is the budget choice., but it seems to offer quite a lot value for money.

Very Very interesting. I've notice over time though that It seems these Head units take too long to start up. I haven't been liking the 5 minute wait for my HU to unfreeze. I may do a Windows Stick to Double Din Touch screen or something
5 minute wait? I know it was a little longer with the factory firmware, and some freezing after a cold boot was indeed observable, but with the Malasyk firmware I don't think a cold boot takes longer than 20 seconds and no freezing is observable after startup. I did notice however that it also depends on the skin that you're using, some of them do indeed cause some lag at startup and when switching apps.
Flat audio with Joying 5.1.1 2-din unit
My Joying unit had pretty flat audio compared to original unit in my car. Joying default equalizer somewhat works, but it starts from 60Hz and even if you crank it up to +15dB you are missing a lot from lower end.
So i installed Viper4Android and it works great! Gives you much more control over audio and fixed my issue.
It's pretty easy to install, you don't need any Kingroots or anything. Go to Settings -> Factory Settings -> Enter password *#hct#root# and after that you should be able to install Viper4Android.
I'm using Joying internal amplifier, i don't know how this works with low-level outputs. I also have latest stock ROM.
Concerning the equalizer: according to my audio measurement, the EQ is a 3-band equalizer with central frequencies of 80 Hz, 1250 Hz and 16 kHz. The adjustment possibility is +/- 12 dB for each band. The 60 Hz, 100 Hz and 200 Hz sliders adjust the 80 Hz-band, the 500 Hz, 1 kHz and 2.5 kHz sliders the 1250 Hz-band, the 10 kHz, 12.5 kHz and the 16 kHz sliders the 16 kHz-band. In order to get + or - 12 dB gain all 3 sliders controlling one band must be set to the maximum/minimum position.

I have the 2nd version. It boots in 20 seconds but the apps freeze and volume can't be controlled for a while

I installed it to. It's Ok but don't have as much higher control like the headphones and Bluetooth settings. I have the crossover clearing up everything for the most part

Are you telling me that MTCD units also have this issue? I was thinking that it's problem with older MTCB units. I do have oscilloscope to do some measuring myself, but right now i don't have time for that. Do you thinkg same hardware mod would work for MTCD units too? Do you have measurements for amp output? I think it starts to fade out badly below <60Hz, maybe they used wrong components for filtering in actual preamp circuit.
Luckily Viper4Android is software solution...
Just an idea.
Wouldn't it be nice to have a DSP app in place of the standard Amplifier app, with possibility to use the internal 4 ch out as active crossover system with optional bi-amplification from the internal ampl?
Think of it
Case A: 2ch (front) with high pass for the tweeters and 2ch (rear) with low pass for the woofers + sub-woofer out. Saves the cost of an active crossover!
Case B: Direct speaker out for tweeters and woofers (front only) would do a great job since the internal amp is quite decent and could save us a lot of money. You only need a pair of woofers and tweeters, no crossover or amps! Just add an active sub if you need more punch

Lcd brightness

Has anyone tried increasing the screen current on a 10" px5 mtce? My kld is borderline in the sun. Ksp is better but has reliability problems. I haven't figured out how the screen opens - maybe there's another way.
If the head unit is connected to the canbus it is possible that the brightness is controlled depending on if the head light is on or off.

Any way to lower Google Assistant voice when using Android Auto?

I have a PX6 6/64 GB head unit and using wired Android Auto with the Z-link app. It works fine, except the Google Assistant / Maps voice has very high volume and distorted sound compared to music. Which makes it impossible to use Google Maps and Spotify at the same time, in Android Auto mode. I have the same problem running stock or HAL9K ROM. Is it possible to adjust the voice volume in any way?
Apple CarPlay works good and has much better volumes and sound quality.
Thanks for any help!
You haven't mentioned what steps you have taken to try to self resolve the problem, which usually ends up in a circular guessing game.
Have you considered lowering the system volume in factory settings?

Thanks, well I have tried rebooting phone and head unit, regarding volume I only have one setting in my head unit, which seems to control everything.
After some more testing I have now realized that the problem is not really that the Google Assistant voice is too high. The problem is that when the voice starts it will lower the music but when the voice is finished it will not turn the music volume back to normal. So when I increase the music volume back to normal, next time the voice will be really high. Anybody else with this bug and a possible solution?
