Stand by issue - MTCD Android Head Units General

I'm having a problem when I turn my car on in the morning. The device boots from start instead of just waking up from stand by. After that, waking up works just fine through the rest of the day. I thought the problem could be a faulty car battery so I put in a new one. It didn't make a change.
It's PX3 chipset.

Does anyone know if the device itself has some kind of battery or capacitor built-in? Or how the sleep mode actually works?

So, it seems it's got something to do with outside temperature. Last night was relatively warm (4°C) and in the morning the device just woke up from sleep upon turning the car on. When the temperature falls below freezing during the night the device starts from cold boot.

Overheat shutdown lock? Defective?

When at the Chicago Blackhawks rally (outside, hot day), my phone apparently shutdown while in my pocket. I reached for it to take a photo, and realized that I could not turn the phone on. I immediately figured that I had activated some resource hogging app while in my pocket, but it seemed unlikely as the battery was mostly full last time I had looked at it. After fiddling with it for a bit, I decided to take the battery out and try to turn it back on. This worked, and the phone rebooted with almost 70% battery life left.
I ended up giving this phone to my wife as she wanted a white phone, and I went and got a red version. Yesterday, the same thing happened to the white phone again. The phone was in my wifes (black) purse, in the sun, while she was in the pool. She was unable to charge the phone or turn it on until she removed the battery.
I can only think that heat is a factor here. Has anyone else had this issue? Is this a "feature" to keep the phone from over heating? Possibly a defect? Unlike an iPhone, the MyTouch doesn't say anything about it shutting down from overheating when it reboots.
Also, I've never had a phone shut down from these relatively mild heat conditions. If it is heat related, this phone is rather temperamental in regards to over heating...
Thanks,
Danny
I has to be a defective device i work in the sun all day few days in over 95 degrees and listen to music at the same time. Never had that problem

Interesting

Today my phones brightness was turned down by itself. So I went into the settings to turn it back up to 100% and there was a message under it saying my phones brightness was reduced to prevent overheating. When I changed it backed to 100% it would bounce back to about 50%. My phone was kind of hot because I was using it while on the charger. After it cooled down it let me change it back to 100%. I thought I would share because I found it interesting.
this actually happened to me the other day i was inside my car it was pretty hot day....
i think it does it whenever the phone overheat to stop any further damage
cool! i didn't even know such safety feature was build in
nice!

Odd charging behaviour last night - can anyone explain?

Hey Guys,
Picked up my HTC One X last week and have had no problems charging the device.
Last night I plug it in as usual using the supplied charger and cable, set the alarm and go to sleep.
When I wake up I notice that it hasn't charged and (this may be unconnected) the alarm did not sound.
I unplug in and plug in back in and it begins to charge.
Interestingly, I checked out the power information in settings and the phone thinks it was charging all night, except, it wasn't.
Anyone else experienced anything like this?
Thanks
Coincidentally my HTC One X was acting really bizarre this morning/tonight too.
I connected it to the charger yesterday and this morning (about 5:30) it woke me up with the "Quietly Brilliant" splashscreen and sound. It seemed to have reset itself and asked me to send a log to HTC...
I guess today will forever be known as 'buggy tuesday'
exactly the same thing happened to me last night. plugged in at 12% woke up at 12% 30 minutes late for work as alarm didnt sound.
seems my phone is having trouble charging today as well as its only went up 3% in an hour and a half and its on airplane mode as im in work!
Wow, so its not an isolated case.
Wonder if its date specific, or has something to do with the Alarm.
Would be interesting to see if anyone else was effected.
My phone seems to be charging OK although I have restarted it since it refused to charge last night.
I do believe under heavy load that the phone will not charge, but as I understand it, a service, or background process cannot consume more than a small amount of the CPU. I did wonder if somehow the alarm has spun out of control and had the system under such a load that it refused to charge.
I just hope its anything but dodgy hardware.
i just restarted mine and its now charging normally so reckon it must be an app or service that was causing it.
the alarm thing could just be coincedence but seems strange...
i usually switch my phone off at night if i am leaving it to charge so i have not got a chance to try this out..
I had a message on my phone last night I have not seen b4. Maybe a similar thing happened to you. The message said "Please close background apps as your phone is using more current than the charger can supply" lol.
as another quick observation, my phone got to 69% charged then got stuck for about 35min.
i restarted the phone again and it started charging again.
i dont see anything strange in the task manager list, and i dont think i have installed anything untoward that i didnt already have on my HTC Desire other than a couple of paid for games...
is there anything i can look at when this happens again to see whats draining the battery? theres nothing strange in the battery usage list either.
currently i have
Screen 63%
Golfshot GPS 28% (i used this yesterday for about 4 hours)
Android OS 4%
Cell standby 2%
Phone idle 2%

Hmm, that's kinda odd. Wonder if the issue I experienced was somehow related.
Just to follow up I repeated my usual routine again and plugged the phone in again before going to bed. Wake up this morning to find exactly the same thing - it hadn't charged.
This really makes no sense and is getting pretty annoying.

hi which version of the OS are you using as it may well be to do with the version of android and software update may well fix this also if you have wifi turned on that can be a large drain on battery make sure if left on it is set to turn of when screen gose of maybe that charger cannot handle it been left on but most likley its a bug in the OS
i found part of my problem was using a lower rated charger. the one i had in my bedroom was 700ma and it needs a 1A.
charged fine last night when i switched chargers.
oh, and my alarm went off fine this morning as well.
still doesnt explain why it wasnt charging, or got stuck while charging with the official charger.
Hey Guys,
One last update!
I have just factory reset my phone after noticing that it would not charge from AC at all and the battery level went from 45% to 100%.
So, Im guessing that somehow, by charging the phone over night, the calibration went out and what it was reporting was not actually what was left.
I shall keep and eye on it!
hi guys. i think that htc rushed with this device to be ahead of all and did not finish the job well,this is why we experience so much problems with this device.no harm intended

Watch turns off and I can't turn it back on.

I've had the watch since December and absolutely loved it while it was working. For the past month, the watch will randomly turn off (without the normal shut down process) and then when I go to turn it back on, it will only show the Huawei logo and then turn back off with a blank screen again.
The only thing that seems to get it to turn back on consistently is putting it back on the charging dock. The watch turns off anywhere from 50% to 80%. So far, I have tried draining the battery to 5% and then giving it a full charge. I did this by "waking up" the watch by putting it on the charger just long enough to boot up and then taking it back off.
I'm also working on a factory reset, but the issue is happening during the re-syncing process (I currently do not have the charger with me) so the factory reset process has been less than successful. Fortunately for today, the watch seems to be turning back on if I let it sit for 5 minutes after it turns off. This made me think of overheating but the watch doesn't feel warm in any way what so ever.
So far I can't find anything on how to fix this except for a forum post on the Moto 360 1st gen having the same issue and that seemed to be a swelling battery problem which my phone does not appear to have because my screen is not discolored.
Is it time to call in the warranty or has someone out there had a similar issue and found a solution. If I can successfully get the watch to sync from the factory reset, I will report back if the issue persists. Any and all advice is greatly appreciated.
Yeah seems like a battery issue. Had the same with my moto. Let the manufacturer repair it.
The battery just would not give enough current sometimes. The output voltage will drop and the whole thing suddenly goes off.
I hope the hwatch has a better repairability score as the moto with all its glue when the guarantee is over...

Bmw E60 CCC android 7.1 no sound on cold start

I bought for one year a 1 Android 7.1 display for a BMW E60. It works great during the summer, but during the colder year I have problems with it. Each time the sound from the audio and video player is switched on, it does not work only from the original radio of the machine. After pressing the reset button on the display frame, the android system restarts and the sound and audio and video player start operating. I reported this problem to the Chinese seller who sent me 3 new room versions so far but the problem has not been solved. Has anyone else encountered this problem at temperatures below 15 degrees Celsius?
My problem is not the same, but I do also have issue with my Android unit in my BMW (E39) I think that this are also temperature related.
Issue that i have is. After shutting down the car, system goes to sleep.
Sometime when using the car within 10 /15 minutes, system wakes up very fast. Unfortunately sometimes , is does not wake up but does a fresh restart.
When leaving the car for longer period, (night) , system always does a fresh start. this was not the case a couple of month ago (maybe warmer temps). Then system always woke up from sleep, even after 2 days of not using the car.
But now, system not only does a fresh start, but a lot of times, light come on, but screen stays black.
Only solution is to press the reset button for at least 10 seconds
I dont know if this could be temp related or power. I wonder if my car shuts down everything using power ,when battery drops below a curtain voltage. (always faster in cold weather)
Last time I had this problem I measured my battery and it read 11.2 volts
I think i need to wait for warmer temps to be sure if this is the problem
It was settled with me. The battery of the car was the problem ... One morning the car did not start because of the battery which had around 300 ah of the 800 ah starting current. I bought a new battery since then at any fresh start of the android system the sound works. I had this problem 2 months, day after day without knowing what to do with the navigation. I never thought it might be due to the battery because the engine started without problems
Thanks for your update. This shows that I am on the right track. For now i will leave it like his. Will see what happens
