[MTCD Android Head Units General] ab1702:
I'm a dab user and I've figured out why mine is poor.

I had an android 6 unit I bought from xtrons and it made the high pitched sound most of the time so I returned it. I Then bought one from erisin and yet again the same problem.

Both times I'm using a glass mount antenna but I have used dab before on an android 4.4 unit and it worked perfect so I know it should work.

Don't get me wrong I am using an older firmware and mcu as I'm new to this forum so I haven't looked up how to update them yet so that might cure it.

Anyhow after lots of messing around I have figured it must be a software/firmware problem as the issue is there when the brightness of the screen on the unit is turned up, I therefore now have to have the brightness of my screen on the lowest setting and now it works fine about 98% of the time. It's as if when the brightness is turned up the unit is taking power away from the dab antenna therefore the signal is reduced. The problem I have now is that if it's a sunny day it's hard to see the screen as I have to have it on the lowest setting.

When I've read up on how to update the unit then I'll see if this solves the problem or not but for the time being my dab is working pretty much fine but I've got to have the brightness of the screen on the lowest setting. If you're not sure what I mean it's the little square at the top of the screen that has a cross which lets you change the brightness when you press it.
[MTCD Android Head Units General] typos1:
Xtrons and Erisin are sellers only, to fins out what unit you have go to settings/about device, the letters after "MTCD" will tell you what unit you have.

To update just put ROM and/or MCU on an SD card and put it in the SD slot, it should auto update and prompt you.

Do you have a powered antenna ?

[MTCD Android Head Units General] ab1702:
Yes I know they are sellers that's why I said that I had bought the unit from them. I think the one I have now from erisin says kgl after the MTCD.

Thanks for the quick how to on updating it. Just one question about that. Would I put new firmware and mcu on the sd card at the same time and then it would update both of them together or should I just do one at a time? I.e firmware and then mcu after the firmware has updated?

The antenna I am using is an active glass mount antenna, so it gets its power from the unit. As I said in my other post it is as if the unit is taking power away from the antenna when I turn the brightness of the screen up although I could be wrong.
[MTCD Android Head Units General] Mattsch:
You Can put both update files in the same SD card at the same time, No problem at all, this is how I do it if I have a new rom and mcu to flash

[MTCD Android Head Units General] BlueVan:
Interesting suggestion, thanks. I will put a voltmeter on the "12 volt" antenna power output from the HU and see if it varies with screen brightness. Have read elsewhere that the output can be less than 12 volts. Maybe that's an issue for the Kinetic. Perhaps I should have run a switched 12 volt direct from the vehicle to the antenna in the first place. Anyway, will report back on results.

BTW If you've not applied updates before - sometimes I find they fail to apply unless I reset (i.e. power cycle, not just reboot) the HU first. I just did the latest GS system update and then the dmcu update failed 3 times. After a reset it went first go.
[MTCD Android Head Units General] Bose321:
Looks good. You only attached that fan? No holes cut? No heatsinks?
[MTCD Android Head Units General] alda.cerny:
If I had an air intake hole there, I would be afraid to take the dust into the unit from the vehicle as write typos1 there https://xdaforums.com/showpost.php?p=73322295&postcount=1906

I have not added a heatsink yet, so it seems that is enough

it is too early to make conclusions, after half a year I'll know more
[MTCD Android Head Units General] Bose321:
Yeah that's a good point with dust. I'm gonna try heatsinks and the fan soon I think! Thanks.
[MTCD Android Head Units General] BobbyZee1712:
Can we expect a Update from google, to fix the freeze problem?

Or maybe from the MCU Updates?!

Or we have to live with the "older" Version of maps forever?
[MTCD Android Head Units General] ab1702:
It may not be that it's taking power away from the antenna I'm just guessing, I suppose it is possible that it could be some sort of software glitch that when the brightness is increased then it is possibly interfering with the dab app?!?

Other type of PX5 head unit not yet found here

Hi,

I recently bought an Eonon GA7150A unit. It has MCU version MTCD_WWW_V2_54b_1 from June 17th, 2017. It does not match with Manufacturers/reseller list of the first post. Who knows who the manufacturer is? Can I use the MCU updates mentioned in this thread?

Btw, I did not change anything yet on the installed software, but it seems to be quite ok. Bluetooth is working fine, no stutter. Sygic is installed. Spotify is running fine. Dashcam is running. This firmware has the option for ACC timeout. Of course, I like to change some things. For example, Gmail is installed, voice commands are not working (voice dialing, Google now etc.)

Thanks in advance!

Hi.. <br />

I have a E3372h 4G/LTE USB dongle.. <br />

Seller of my MX Headunit says it should work.. But No Luck.. <br />

<br />

Why? <br />

<br />
[MTCD Android Head Units General] typos1:
Dont take any notice of the manufacturer/reseller list in the first post, its total nonsense - resellers often sell units from several different manufacturers and who you bought your unit from is totally irrelevant anyway, its who made it thats important. [MENTION=2370138]aarick[/MENTION] should separate the list of sellers from manufacturers as it just causes confusion, in fact removing the list of sellers would be even better really, on xda we dont really care where you bought it. If this was a BMW forum and you asked advice about your 320d, no one would ask who you bought the thing from cos its not relevant for tech support, the same goes for these units.

Yours is made by a company abbreviated to "WWW", thats a new one, not heard of it before. The rule has been ONLY use MCUs from the manufacturer of your unit - ie only use KGL MCUs on KGL devices, however, recently [MENTION=4974080]marchnz[/MENTION] has discovered that a lot (but not all) of units can run MCUs from other manufacturers, see his "Cross compatible MCU" thread for advice and info . . . if you cant wait until a new WWW MCU comes out. In fact, rading the rest of your post, I d leave it alone . . . unless you get a problem.
[MTCD Android Head Units General] lefterisa3:
I have the same unit.

Contacted their support and they send me a mtcd kld file.

So can confirm its a kld (klyde) as usual for eonon.

They just modified the name of the mcu file
[MTCD Android Head Units General] typos1:
Strange.
[MTCD Android Head Units General] ikerg:
Perhaps the WWW is experimental software of the manufacturer and the update to KLD prior to send it to customer....but it indeed sounds strange

On 3G i get 12dl / 7ul

But normal my 4G speed is over 100mbit
[MTCD Android Head Units General] Alexdepalma:
Did it fix de echo? No more echo? Do you have dual microphone or only internal one?

Your BT audio setting?

I have tried 2.51 and 2.56 with the proposed solution by [MENTION=1696724]fx1[/MENTION] without success. Some improvements but not fix.

Any body else fixed Bluetooth echo problem with new firmware or only MCU updates?

Thanks

[MTCD Android Head Units General] Eventer_:
Is there any info about a new stock firmware? latest stock fw runs not really good. Stability is worser than the last firmwares.
[MTCD Android Head Units General] typos1:
The echo will never be fixed with firmware, it cos the internal and external mics are wired together, your ll need to separate them by removing a capacitor.
[MTCD Android Head Units General] Bose321:
Do you happen to have a picture of which one exactly to remove, and how to safely? I'm planning on installing an external mic soon.
[MTCD Android Head Units General] typos1:
No sorry, its usually capacitor C32, but not always, but this is a problem with the motherboard, not the SoM and each manufacturer has a slightly different motherboard design.

I would search the MTCD forum for threads about it, including threads about RK3188/PX3 and Intel Sofia units - the motherboard on them are the same so as long as you find some one who has done it to the same MB as you have it ll work.
[MTCD Android Head Units General] f1x:
Unfortunately, this is a software problem. I described what is wrong sometime ago. If the system is not overloaded, then echo is cancelled very well. Problem appears when you overload the Android (e.g. by launching an app). I observed what happens during hiload, and it looks like SCO stream and MIC stream got completely desynchronized (shift is around 500ms). That is too much what WebRTC AEC algorithm can handle and this is the reason why echo appears.
[MTCD Android Head Units General] typos1:
Possibly thats a factor too, but its also a known problem (established for around 3 years) with MTCB/C units and MTCD units - the mics are usually wired together and the mic mod massively improves things.

I ve never heard of anyone complaining of it "sometimes" ie only when theres a hi load.

Doing the mic mod is simple and easy so I can only suggest to do it (wiring them together is bad design anyway) and retesting to see if you get the same results from the algorithm.

Of course it may be a due difference between motherboard design between manufacturers, what unit have you got ? You could also go through all the threads in the MTCD forum about the mic mod and see if anyone with the same motherboard as you reports the same problem.
[MTCD Android Head Units General] f1x:
I am 100% sure that echo problem is not related to the wiring. I can talk for 10 minutes without echo when device load is stable (nothing is running in the background). Right after I perform any heavy action like launch of google maps, echo appears. I modified the gocsdk and added some prints to figure out what actually happens under the hood when load is growing. I found that SCO latency dramatically grows which cause echo.
[MTCD Android Head Units General] Bose321:
Would that maybe also explain the stuttering/glitching sound you can get from apps like Spotify when there's load? I find that listening to Spotify works fine, but when it's hot and/or the device is under load and the CPU is throttling it starts to lag and stutter badly.

Have you also tested if the echo problem is there with proper cooling? Like after installing a fan and some heatsinks. Or is is purely CPU load?
[MTCD Android Head Units General] f1x:
Yes, it can be similar issue. It looks like bottleneck inside audio drivers. In case of echo, throughput of the microphone drops from 80 frames to ~32 during high load.

I did not add any cooling to the device, but tested the echo on completely cool device. It appears right after the load is growing. Changing CPU governor to performance does improve nothing. It looks like problem is related to the I/O latency rather than device performance.

SBC frames are decoded in chunks of 48 bytes (24 PCM frames, 2 bytes each). Audio from the microphone is captured in 80 frames period (160 bytes). Latency of the particular frame should be 1/8000 -> 125us. And this is true when load is 0. When load is growing, latency of the frame capturing is around 300us for one frame. That is way too much for the AEC.
[MTCD Android Head Units General] typos1:
Maybe its a problem with similar symptoms ?

I guess if someone has a unit that was RK3188/PX3 that they upgraded to RK3368/PX5 and they didnt have the problem before but they do with the new SoM that would confirm it.

Nevertheless it STILL could possibly be improved/sorted with the mic mod - because the BT is MCU controlled NOT Android controlled.
[MTCD Android Head Units General] Nomader0:
i had a px3 and upgraded to px5. and i never had an external mic.. only internal

I tend to agree with f1x.. the echo appears after sometime is spent on the phone

at the beginning of the call there is no echo whatsoever.. this can last to several minutes sometimes 10 minutes.. then after a while echo appears..

i have tested this in 3 units1 px3 and 2 px5

I don't know why but this thrown me to the bootloader screen. The options of Reboot, Power OFF, Restart, Recovery is changing again and again. I think there is an issue with Bootloader.

I have installed the Factory image, and still, the issue is same. I have successfully started my phone, but the issue is that it is in safe mode. If there is a problem in the volume Button, then the volume would have increased and decreased randomly. I think the issue is something else.

Wi-Fi was working fine before ,but after i soft-bricked it and then reinstalled the factory image the Wi-Fi wasn't working. Strangely, the Bluetooth was working just fine.

[G3 Q&A, Help & Troubleshooting] trakvh:
Hi, so a week ago I had this weird problem with my phone. It would just freeze for like 2 minutes, work again for a minute and so on.

Did a hard reset, same problem.

Flashed that 6.0 KDZ, no success. The phone started but I was basically stuck at the lock screen, touchscreen was unresponsive, power menu kept showing up for no reason... couldn't even turn the phone off.

After that, I decided to stop ****ing around with it and send it to a repair store (no warranty). Today, after about 5 days, I picked it up and was told that they tried a ton of ROMs but they have no idea what's wrong with it.

Got home, ran a hard reset again and now I can't even get to the lock screen, phone is basically in a boot loop. LG logo shows up, the "Android is starting... Optimising apps" screen does its thing, restarts and keeps going like this forever.

Is there anything I can do or should I just throw the phone in the garbage and get another one? Any suggestion is appreciated, thanks!
[G3 Q&A, Help & Troubleshooting] Esakama:
Hi,

Same issue for 2 days...

My G3 was suddently slow and unresponsive so I removed the battery.

I put it back again, as usual, and start the phone. But it get stuck at the LG logo.

Sometimes the animated LG logo shows up, sometimes not.

Sometimes it displays the PIN screen (unresponsive or not), sometimes not.

Sometimes it boots totaly normaly (1% of time) and become unresponsive/buggy after a couple of minutes.

I tried flashing kdz (normal and CSE) 10 times, factory reset, change battery, without success...

Good luck.

Hello,

The past week I've been reading and watching tons of comparisons and reviews of the new devices in the market and i refined my options to these 2 amazing Oneplus 3t and huawei mate 9 pro. They are very close to each other almost on every comparison tests and each one of them has pros and cons making it really difficult to choose between them.

I speak for myself I'm more into mate 9 pro but im little worried about the future support as this device released several monthes ago and yet no root available for it and quite few updates released. also there is no subforum for it till now in spite of mate 9 and 1+3T have theirs.
