I have recently purchased the original Samsung car holder.
After my tab reaches the 100% full charge, it beeps and advise me to disconnect.
If I don't do it, the tab itself begins to overheat after some minutes.
It oveheats really hi ! On the right side of the tab.
It seems like the car charger is not able to stop charging, differently from the house 220V charger.
Have you experienced something like me with your car charger ?
I have been using the car dock, sinds the beginning. Cannot say that i have noticed any excess heat. Note: i have used a brodit clip to install it on the air vent. Nicely in front of me without blocking line of sight.
All the phones i had "overheated" when connected in a car dock, having a forced air flow over it quickly eradicates this problem!
I use my tab in my car using the usb cable and a generic usb 12v adapter and it doesnt overheat, even when using the tab heavily (screen full bright, Torque app, and Pandora).

Ok, thanks for all your answers.
Could I ask you all, if you use bluetooth in your car?
I use bluetooth ON to stream music from SGT into my car stereo.
I mean it could be an overheat problem caused by the bluetooth antenna, isn't it ?

I never use bluetooth.

I have bought the original dock nearly one year agoand it overheated only one time (car standing in the sun). I use my tab with Bluetooth and wifi activated.
New experiment:
I have put it in the car dock, no wifi, no bluetooth. Only 3G + Google Navigator were ON.
It reaches 100% and after become very hot (in the right side)!
Now I need to try again with display off, and 3G off; only power charge.
And finally I will understand (as I suspect) there is something it's not ok in my car dock (I remember you that with my original home plug cord all is ok !)

Adding to my post earlier, and answering your question, my audio is through bluetooth while I am running those apps.
It's even two bluetooth connections... Pandora and Torque at the same time.

Yeah, i think you're right. Without being an expert: Sounds to me, like it doesn't deactivate after the battery has reached 100%. As I understand.d you, it becomes hot after it is loaded to full capacity, right?
You should try to exclude all functions, that may be the source of this malfunction. Put it into flight mode and just try loading the tab. Then start activating single functions like wifi etc. After that, you can try combinated function.s like Bluetooth and wifi.
I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.
I really like the idea of using the magnetic charger as my main source of charging. But using the magnetic cable has caused some big annoyances. First of all, the screen rotation. My display setting is always set to portrait lock, but when using the magnetic charger it ignores it and rotates the screen 360 degrees. I even installed the xposed module 'disable desktop lock'(made for z1) with no succes. And secondly, most apps restart or chrome pages reload when inserting or removing the charger. Even though YouTube doesnt seem to behave this way.
I think these behaviours are built in features for the charger dock but since I'm using the charger cable these features seem useless and are simply annoying.
I can't find anyway to disable them. Does anybody experience these same issues, and is there anyway to disable them?
EDIT:
sorry, just fount that the xposed module 'disable desktop lock' has been recompiled for the z3c. this solves both issues. see llink to original post.

When I plug in my huawei p20 pro its always set on" Reverse charging" by default, so I have to change this setting to "Charge only" to be able to charge it. Is there any solution for this problem?
Is this the same every time? With original charger?
Reverse charging issues
I'm having the same issue with my Huawei p20 pro, but its also giving me a notification "supplying power to connected device over USB" even though nothing is connected to the phone.
Supplying power to the connected device over USB
Same issues here too, even though the charger is not connected still getting this notification, battery seems to be draining fairly quickly too. Help much appreciated, thanks.
Maybe the usb port needs to be cleaned. Try with an air jet,don't use any liquid.
SOLUTION!!

Hi there I bought a Huawei P20 pro 128 GB 2 weeks ago and 3 days ago began having the same exact issue, It would only charge if I turned the phone completely off, and when it was on it would be stuck to the setting reverse charge even when I had nothing connected to the phone it would continue telling me I am currently connected via USB and reverse charging.
THE SOLUTION was CLEANING the USB port, Mine had a little bit of dirt and possibly a touch of corrosion which provided a point for the phone to discharge. the phone thought it had a USB connection and was trying to reverse charge it. So I used very small tweezers off of a jackknife and lightly scraped around the connector of the phones USB port and the phone stopped saying it was connected and reverse charging, and began charging normally when I connected it to USB! So clean the port, done use liquid but maybe a small pin or tiny tweezers and lightly scrape all the surfaces within the phones charging port until the notification that the phone is reverse charging goes away! Do be delicate though as scraping it to hard could cause something to break just do it very lightly
Thanks let me know if that helped fix yours aswell!
