Ok well I'm running Fresh 1.0 rom (and have been running it for 2 weeks now)
And I was using the wireless tether application (and have been using it for the past week)
While I was browsing the web, my signal just disappears and my phone turns completely black. It was charging the whole time and had battery which was green. I've been charging it but it wont turn on any time I press the power button.
Any suggestions?
Battery Pull??
Does it do anything when you press power? Does the status light change or anything? Try holding home down when you press power to see if you can get into recovery
your battery may be overheating. I use a battery monitor widget called "battery life" and alerted me that my phone was shutting off for heat related problems. I alleviated the issue by taking my phone out of it's protective case that I recently bought and placing it on a cool metal surface.
After it cools off you should be fine. Or the heat may have killed your battery although I think that is unlikely.
uh oh, what case do you have that wasn't allowing it to breath properly?
hard plastic case from handhelditems.com
You absoluetly MUST remove any kind of casing when using Wireless Tether! Overheating is a common problem with the app, especially if you are pushing serious bandwidth through it. Try and remember that the phone was never really meant to be a wireless router, and using it in such fashion will result in additional stress to the hardware. Honestly, I would keep the phone on a chill pad or have a fan directed at it while running tether at full blast, or try and keep your bandwidth load to a minimum. Use a dedicated line for your torrents, use tether for on-the-go browsing!
I can only imagine torrent traffic would throw a red flag to Sprint also. So keep that in mind while tethering.
I don't have any choice but to power it on the AC. It was connected at the back of my receiver (Yamaha) but unfortunately the USB on my receiver is in front but I'd rather use its own power for a clean look. The problem right now is the chromecast is always on. I can see the white led is always there. I'm afraid this will not going to last if its always on

I don't think you will have a problem with it being always on. If you are really concerned, you could always get one of those Green power strips that turn off specific power ports if the main power port isn't in use.

I agree that this shouldn't be a concern. Most modern LEDs running at standard intensity 24/7/365 should last 8-11+ years. You should be asking yourself if you expect to still be using your Chromecast over a decade from now. Also: When was the last time you saw a consumer electronics device in use with a dead LED?

i am not concern with LED, this morning i checked the device and hold it and its really WARM.

I have a tuner/amplifier that I still use to power my small Bose speakers that is from the early 90s. The LED panel on the front is burned out so its no longer useful to tune radio stations, but the amplifier still works as well as it did from day 1. Amplifiers are hundreds of $$ for one with similar wattage, so i have continued to deal with its problems.
The manual says nothing about overheating causing damage to the device.
All that the manual says is to unplug it (to let it cool off) before removing it. Heat shouldn't be a problem.

Does your receiver have a 'switched' outlet on the back? That outlet will go on/off with the receiver. You could plug the Chromecast into it.

this is the first idea but no outlet at the back. no choice, i transferred the usb now in the front. no kidding, the chromecast is running from hot to warm.
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.

It's very low power draw (someone recently checked it with a Kill-A-Watt) and having it on continuous power means:
Much less chance of mishap during a firmware update (since they happen without you knowing)
It can turn on your TV and switch it to the appropriate input, if your TV or connected device supports HDMI-CEC. Mine is connected to my sound bar's input box and it seems to change the TV to the correct channel as well as the sound bar box! Magic!!!
So many things don't turn "off" now. Instead they "sleep." My Xbox one is never "off", my blue ray is never " off" either. Its such a low power state that who really cares. I've tried to get my power bill down to the days of an apartment, but its impossible.

Just about everything is computer controlled, uses some variation of Flash memory and all of that needs power...
Imagine if you had to wait for your TV to boot up before you could watch TV.
Or for your Router and Modem to boot up every time you wanted to use the internet...
almost nothing these days actually shuts off entirely.
I only plug it in to use it. When I'm done I pull the power cord from my usb. I worry that it could be in the middle of an update and if I turn off my TV something bad could happen.

Same here.
It's installed in the man cave anyway. If I'm not going to be down there for a week, why let it draw power. But that's me...I'm also the guy that goes around behind everyone turning off lights and shutting things off that aren't being used. PC gets shut down at the end of the day and doesn't get turned on until its needed the next day. Laptops at least go into Hibernation. I don't leave phone chargers plugged into the wall either if they aren't charging a phone. Maybe it's an old school thing. LOL

If you want you could always cut open a USB cable and just install your own on/off switch on the 5v power lead. The wiring diagram for USB cables is on Wikipedia.
But just out of curiosity I got out my own power meter and checked the Chromecast. It consumes less than 2 watts on standby with the screen background photos cycling (that's the lower limit that my power meter can read). While playing a Youtube video it's still only 2 watts, though from the way the reading varies it looks like it's slightly higher than standby. As far as I can tell it's independent of whether the TV is on or not.

I'd shut down my PC save for the fact that it takes 20 minutes to become useable. Maybe I need SSD, heh.
I have some smart power control devices (TrickleStar, APC green UPS) too.
One thing I learned only a few years ago - if you unplug a battery powered device, DISCONNECT the device from the charger!
Even though it's not supposed to, some chargers allow some back flow and slow drain the device's battery, killing it.

Yep there really is no point to trying to save power without just going over and unplugging it....
As of now there are only two reasons I can come up with for really wanting to power off a CCast...
1 - The damn thing will change inputs anytime it reboots or updates
2 - The CCast gets pretty hot after awhile...It just seems like the kind of device that if you do not have a conditioned power source coming into the house it could easily fry.
On a more serious note if thats all your worried about (not Power use) then anyone who has one of those X-10 Home automation systems can easily plug the CCast into a module and shut it off from the phone or tablet.
And if you don't care that the CCast can't turn the TV on and the TV has a USB port thats probably the best way to save power.
I personally don't trust the TV to give it stable power and you will find yourself having to unplug it anyway to reboot from time to time...
If you really have issues with a high Electric bill there are far better ways to save on that bill than powering down a CCast.
Even something as simple as keeping your Freezer fully packed will save more money in the long run than the few hours the CCast is unplugged.
I don't mind it consumes energy, it is very little but I am more concerned about the fact it will be broken faster. It's like a light bulb, when you are not using it, why does it need to stay on and will need to be replaced faster.
Also the chromecast gets quite hot. So without turning it off, it never gets a chance to cool down.

Well the truth is silicon is not as fragile as a Light filament is...
Power Surges worry me but not just the act of being powered on....
It makes sense that it would be an always on device considering it needs to be there when you want it...
But some sort of sleep state might be a nice addition to any next generation model which I hope can also be wired to the network and use Wake On Lan to full power up when you want to cast.
I'm curious about the technology inside the LED Cover - what powers it? What's behind the display tech? How does the phone send it information?
Does anyone have any insight? I figured NFC explained most of it, but I was surprised to see that it functions fully with NFC being on.
The case gets power from the phone in similar way as wireless charging, or s-pen and those LEDs don't need much. I think it uses NFC for communication and I suspect there are some magnetic sensors that trip and let the phone know the cover is there, so NFC switch off maybe just mean it won't communicate with anything else, but cover.

So I guess some sort of conductive power method? I didn't even think of how the s-pen works - it's more than likely the same method.
Magnets
For clear view LED cover you will notice a round thing on the cover. It is a magnet. On the back cover also sme magnet.
LED works by magnetic induction.

Actually NFC works with the cover on, but only when the cover is open - ie. phone is unlocked. I have no problems with pairing my NFC headphones with the cover on.
Does this mean the wireless charging in the note 8 goes two ways?
Not only can it be used to receive a charge, but it can provide a charge, too?
Are there any other mobiles that can do thee same? Or is it a common feature?
Its using NFC which has a small wireless charging component to it -
The NFC / paywave function on your credit card recieves a small amount of power which powers the chip and they can communicate at 13mhz.
The power supply can be up to 2.3 volts at 6 milliamps. Thats enough to power a few tiny LED bulbs.
As with all wireless power, it is incredibly inefficient and so i see it as just a battery drain. Probably would have been better to use a semi opaque window in the case which just shows the phone screen and positioned a clock to show through, building on the Always-On Display feature.
I've been using the LED case for several months now and I did not notice any significant battery drain. Keep in mind the LEDs only light up when you either hit the power button, close the cover or when a notification comes in. They never stay on for more than a couple seconds. Also note that when the case is closed, the AOD is turned off, saving whatever power those pixels are consuming. So AOD always on vs. a few inefficient LED's on for a few seconds. I'm sure it all depends how often the LEDs are turned on as to whether you consume more or less power.
As for just having a window, well then you would not have the touch gestures on the case itself. You can answer or dismiss a call by a swipe on the display of the case.
One thing I noticed when using the wireless charger is that charging stops once the LED case front lights up. Charging resumes once the LEDs disappear.
It's a flaw. Everytime I must flip open the case to do wireless charge.

The S-Pen gets it power from the electro-magnetic grid that is under the display. But it has to be close enought to the display to receieve a charge.
