High pass filter - MTCD Android Head Units General

Hi, I want to purchase one of these ebay.com/itm/10-2-Android-8-0-Car-Stereo-GPS-for-Toyota-Highlander-Radio-Navigation-Headunit/253956386150?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055359.m2763.l2649&autorefresh=true and was wondering if you can set a high pass filter for front and rear but have it not effect the subwoofer output. Also anyone else out there have any of these specific units that could tell me how they like it.

Evo Video Questions...

So I recorded some videos in a dark bar yesterday and they turned out... surprise surprise... terrible. The lighting was bad, and sounds was clipped. etc... not that I really expected much.
I did notice some odd things. First is that the frame rate was 13.7 for some reason. Is this because of the low light and it needed to expose the camera higher? I would have rather they raised the ISO or darken the image then lower the frame rate from 24p.
The other is that the audio was 8bit... I know that the mic can't really capture much, but I am wondering why not give it a little more room.
The last question I have is what formats can the Evo play locally? I tried to clean up the video and audio as much as I could on my laptop and want to put it back on the phone. Anyone know?

SWR50 Accelerometer/Gyro

I am interested in making some vibrations measurements using an SWR50 smartwatch. I have been tinkering a bit with it, and making a tiny app that samples and stores accelerometer data. While doing it, two questions arose:
Which is the accelerometer/gyroscope chip installed inside the watch? I have been searching teardowns of this watch to get it, but the only one I found doesn't have enough quality to read the reference of some chips. I'd like to know the part used, to browse its datasheet.
I'm getting a maximum 250 Hz sampling rate. Is it possible to obtain a higher one? Reading here, it looks like there is no conventional way of doing it, but I'm wondering if maybe hacking through OS images...
I'd like the measurements to be as precise as possible, but it looks like it can be tricky obtaining good results.

Need Help Quick!! Camera, Sound and Display.

Hey, Mix 2 is going on sale tomorrow in India and at the last moment I'm confused whether to buy it or not. The main concerns being camera performance, the sound quality and the display. Help me out please:
Display: After rooting is anyone able to get videos from youtube and other sites running full screen (i.e. 18:9)?
Also do you feel the absence of AMOLED screen of QHD?
Camera: I've heard from multiple sources that even though the camera sensor is same as in g6, it doesn't fair as well because of software drawbacks. Has anyone tried the google camera port to find any improvements in camera quality?
Sound: Is it decent enough for watching movies with another person?
The Screen is bright and has nice colors.
I do not notice that Landscape video is "letterboxed". Having com from phones with large top and bottom bezels, a little extra black space on the sides disappears.
Sound is a little low, but good quality from the speakers. No problems if you connect a BT speaker.

What about the camera? I heard picture quality isn't great because of software drawbacks. Is it so? Could you try the new google camera v5.1 for any improvements?

I do not notice any difference in the camera and with my former phone, a Nexus 6P. Supposedly the Google HDR+ camera port improves the quality, but I have not bothered yet.

PX5 Headunit Display issues and concerns (Brightness/Burn-in)

I have a MTCD PX5 unit I bought about 3 months ago - seems to be a KLD unit based on research around its MCU. I have some concerns around the quality of the the LCD used and some issues with it. I don't have any other Android HU to compare it to so I thought I would open up a thread and get some feedback based on what others experience with their units to determine if this is normal.
My concerns:
- The screen is not bright enough. Does anyone else experience this? During a sunny day, the LCD is very reflective and not very bright (even though I have brightness set to max), making it difficult to see. In the late afternoon when the sun isn't so strong, its much better and easier to see.
- I experience burn-in from elements on the page that don't move. This becomes apparent when I change over to another screen (especially when its a plain screen with not much on it like a blank web page). I can see elements such as logo or music controls still displayed as if the pixels haven't updated yet. It goes away within a minute or so but wondering if this is normal as these LCDs are probably low quality. You can see it on the 3rd image, I use car launcher AG and after a while when I changed to a plain screen you can still see the VW logo and other buttons from the launcher still visible.
I just want to check if these issues are normal or if my unit has a bad screen and I need to replace via warranty. I've attached some examples.
Screen on my unit is an 8 inch LCD with resolution of 1024x600
Concerning the brightness I would say this is quite normal. All units I have seen yet seem to have around the same brightness level as visible on your pictures. I did apply a protective film on my unit with matte finish which reduced reflections and therefore improved the situation a bit. However still the screen can't keep up within direct sunlight. I actually thought about modifying my unit and checking if it's possible to boost the backlight. But certainly this requires hardware modification and might have negative impact on contrast and colors (which isn't that important while driving or using navigation).
Also there are 2 brightness levels if your unit is connected to the car correctly. One level is set when headlights are off and one for headlights on. The headlights-on setting can be configured individually in settings and is typically lower brightness for nighttime driving. Still I agree the highest brightness is too low and the lowest brightness is to bright. Fortunately the KLD units typically have a "screen off" button in the notification bar. So it's possible to turn the screen completely off. Very handy during night drives.
Regarding the burn-in effect: I didn't notice this yet on my KLD unit but it might heavily depend on the screen type. They might even buy screens from multiple manufacturers just to get the cheapest offer. So yes, you might have got a bad quality LCD screen even though it's not defective. I will try to keep an eye on my one if I notice the same.
I've got an ATCGFEHNY unit which I think is just an XTRONS for my W211 mercedes. Having same kind of LCD Burn In issues. If anyone knows of good replacement touch LCDs please let me know and I'll rip this thing apart and swap it out.

LCD Viewing Angle

I recently purchased the 9" unit from AVIN and the LCD panel is completely washed out. The image is great if I view it from my armrest so I'm wondering:
avinusa.com/bmw-3-series-e46-m3-9-oreo-8-0-4gb-ram-32gb-navigation-system.html
1. Is this normal? It's like the panel was installed upside-down.
2. Can I purchase a compatible LCD module with a better viewing angle?
Mine is similar. I think yours as well as mine is not IPS screen. I'm very close to just get another one with IPS and hopefully better bluetooth as mine (725) is a steaming pile of S.... Just make sure if you decide to order something that it's specified as IPS. If for some reason this is not specified then you shouldn't buy it.
