help with samsung galaxy tablet 2 power button !
*Hi guys*I'm finally making the move and have bought a Samsung galaxy tablet 2 for my bmw e46 dash but have found a problem and wondered if any of you guys have a work around for it ?As you know the power button is on the edge of the tablet externally so once it's installed behind the dash you can't push it to either lock the screen or take it out of sleep mode and also it doesn't matter have a proximity to sensor built in etc*Any idea how I can press this power button while it's behind the dash either by the touchscreen using an app or another way that anybody can think of cause I'm stuck ??*So help ppl**
I've read some people use an app called TASKER to set it so that when they crank the car (giving the tablet power thru the charger) the screen comes on and stays on till its turned off. maybe check more into that?
use a custom rom with volume key waking up option.

If he won't have access to his power button after mounting the tablet in the dash, he probably won't have access to the volume buttons either.
here is a thread from another site where a guy put a nexus 7 into the dash of his vette http://ls1tech.com/forums/stereo-electronics/1584175-c6-android-tablet-stereo-dash-install.html
If your'e thinking about doing a hardware mod , Try AdamOutler (XDA TV) He does some pretty cool stuff and may offer some solid advice. Knows his stuff thats for sure.
XDA unboxing /tutorial Adam Outler style
Guess you could move the power button onto the dash itself if the device is getting built into it as a permanent fixture ? Not that id have a clue how to do that lol.
Not making any mod to the tab: You may mount a solenoid, http://www.solenoidcity.com/solenoid/solenoidcatalog.htm on the dash to actuate the switch. Will require some mechanical / electrical skill to accomplish the job..
fixed?
did you ever find a solution.. I have the same car and the same issue
Thanks!
Thing is you can easily get apps from store to
1.lock screen
2.turn off tab
3.toggle volume
But real problem comes with turning on tab...
Though you can turn on tab from sleep via some apps called smartawake and others(believe of there are lot of them on play)
By these apps you can turn on tab using proximity sensor(it will work),vibrations
But for instance when your tab gets off you have to press power button.
That can be done by pressing in physically or a hardware hack(you got to open up your tab and do stuff with your power buttons.like providing external switch to it etc)

Hey guys I am having a similar problem with my galaxy tab install in the car. I come out in the morning and the tablet is dead. I am currently charging it via usb but was planning on putting a power inverter in the glove box for faster charging (maybe?) What I would really like to do is to be able to extend the power button leads to an external button that I can mount in the dash. Anyone done this before or have any suggestions?
Someone recommended Tap Tap App (lock and unlock the screen with a double tap on the proximity sensor) around here. I've tried it and it works.

Yea that would work for turning the screen on and off, but im talking about if the tablet dies completely. It will be getting charge when I turn the car back on but I wouldn't be able to turn the tablet back on itself because I can't get to the power button.

Your Tab will boot into charge mode. Maybe you can change the init script logic: if boot into charge mode, wait a minute, and then reboot into normal mode.

Now that would be awesome. I am a total noob with stuff like that. How would you even go about something like that?

There are some changes that can be made to the kernel to boot the os when powering the tablet. I had this behavior on my lgp500 as a bug on cm builds. To keep the display on you can check keep display on during charging.

I'll try. But now I am so tired, back from my real work duty. A short break after driving my car for about 3 hours, 1 hour from home 3.49AM here
Just to over simplify the first thing that came too my mind was a knob with an off set round plug on the other side...turn the knob you push the button..

Let's say someone managed to pair the watch to something that it's not compatible, say, a windows phone.
Now the watch is stuck on the screen that wants one to open the Smart COnnect app.
We all know that windows phone suck and doesnt have app for ****.
So how would one master reset in order to repair the watch to an android os phone?
Let's just say that holding down the power button for 5 minutes did nothing as well.
What's your solution to this problem?

In this situation coudn't you try to connect from an Android smartphone?
Other attempts: try if recharging the smartwatch unlock the screen, or let it discharge completely.

That's the weird thing, it wont pair with another phone since it's at the screen with the smart app request.
Sony's site want me to hold down the power for 15 seconds, or go to the Settings menu and select Reset.
The later choice is not an option since i cannot access the menu.
Gonna give the battery drain a try.

I'd try the power button first of all... if you keep it pushed the watch should power off and then you'll be able to power it on again and restart the pairing process...

This has happened 2 times lately, at least once for sure while on the charger over night.
I wake up,and have notifications from over night so the light is flashing. I try to open the phone,and nothing happens . The phone is very hot also. So I long press the power button and up volume at the same time,and phone vibrates 3 times , then shuts off. I can then turn the phone back on ,and after a few min it cools down, and operates normally.
I purchased this device from a sony store in Thailand where I live ,and is is unlocked. Please Please help me figure this out. Thanks in advance. Everything is up to date also. The phone has onboard diagnostics, if turned on it can send information to sony to help find problems. Should I use that system to help?
Thanks again, B
Check what apps you have given permission to provide notifications. Sounds like one is possibly looping.
Looping app??

I hope this screen shot attached. Check these usages for me please. What do you think? Thanks.
Doesn't look like anything there would cause an issue. I don't have any issues and I don't use stamina mode. Possibly try it a couple nights without stamina mode?
I'll try it. Thanks
I have a Samsung Galaxy J7 and there is no ROM on it. It had TWRP installed and working, but today it stopped booting. If I push the power button
nothing happens like the battery is dead. I went ahead and bought a new OEM battery and put it into the phone. I plug in the charger and for a
few seconds, the black screen shows a battery in the middle with a lightning bolt. Then it goes back to black ... I let it charge overnight but when I
go to turn it on, it still does nothing. no matter how long I hold the power button, nothing happens. I tried power + home + Vol and still nothing.
Just a black screen and no LEDs light up. Nothing ... if I plug it back into power the battery icon shows again in the middle of the screen with a
lightning bolt, then goes back to black.
What could this mean ?? Is there anything I can try ? the phone was booting into twrp just fine until today.
Please help !!

Flash stock rom latest with odin
Charge the batteries outside of the phone, with a standalone charger first.

Mmm ok I can try, I am very new with this phone, but have much experience with Odin and flashing, could you please point me to
the Stock ROM I should use?
Will this one be ok to try ? https://forum.xda-developers.com/galaxy-j7/j700t-development/rom-optimum-stock-v1-fullofhell-t3701168
Thank you so much ...
PS...( dodo224 ) I do not have a standalone charger to charge with so I can not try that method of charging. I will try Odin tho.

I dont have that phone so cant suggest you any roms, just make sure its stock and latest. Also i doubt that its a battery issue as a brand new battery has some charge which should have turned on the phone when you tried.
you can download your stock rom here: https://www.sammobile.com/firmwares/
download the latest one.

Hi -
I am a bit confused ... how can I flash anything if the phone will not turn on ? I can't even use Odin. If I push the power button on the phone
nothing happens. The only action I ever see is when I plug in the power cord to the phone, for about 5 seconds a big picture of a battery
with a lightning bolt through it, then the screen goes black again.
Thoughts please ???
Thank you
PS. I have tried different chargers and different batteries, but still the same result's.

Since you're new, have you tried pulling the battery, putting it back, then holding power, home, and volume down buttons simultaneously? It wasn't clear if that was the problem with using Odin or not.

If you have usb debugging on, there might be a way to reboot system in download mode. Its tricky But it works i guess. Try to Google some thing about soft brick. Im busy with work so not checking xda quite often. Sorry and good luck

Hi again -
first off Yes I have tried power-vol-home but again nothing happens. No screen. Just black. The ONLY TIME the screen comes on is if I put the charger into the phone..the screen ONLY comes on for 5 seconds displays the battery and shuts OFF. I have NO ROM / NO TWRP. . it is all gone. I had TWRP but if its there I cannot boot to it. No fast download / download / recovery nothing happens, only the battery ICON for 5 seconds. I have tried three batteries and none of them will help. It will NOT charge either.
Also Sandeepkumar - sorry I was not clear. There is NO OS. No Rom. So there is no way to turn on usb debugging. Please help ! If you have any other ideas, or you need any more info from me
Thanks again all !!
PS... Just so you all know, It was ALL working prior to this. It was rooted/TWRP/Custom ROM ... all fine. Then I deleted ROM/OS by mistake from TWRP, then this all happened

right, so now what we need to do is , connect your phone to computer while the device manager is opened on it. that way we can check if computer recognises the device in any mode. if it shows something in usb section then maybe we can look for a way to bring the phone in download mode or some other mode.

Okay, we must not check this pc for the device, open device manager using windows + X. Then selecting device manager from that black menu that pops up. Inside device manager, look for the list of usb devices, it should be near the end of list. Now when you plug a usb, you either see usb mass storage device or you see unrecognised device. Check what happens when you plug the phone and battery sign shows up

Okay, so if the phone doesnt show up in device manager then i guess there is nothing that we can do. I have ran out of ideas. Maybe its time to send it to customer support.
As you're trying all this, is your battery fully charged?

Oh ... Well I assume it doesnt show because it is not turned on. I guess my only option is to get a standalone charger and charge the battery then try again ,,,
Other than that .. IDK.
thanks anyway .

I hope you get the device working. Good luck and please share what happened.
FYI I charged the battery in a universal charger, now phone boots fine. Battery was just too low to take a charge from phone.

I have my android in car, and im selling android stereo to clients!
They ask me they want when they turn off the key and turn it on again after few seconds they need the android to be restarted!
Because the current mode is: when they turn off the car key for 2 - 5 hours, the android still backed up the data in the last state, but they want to restart the android for every key TURNED OFF & ON!
I have an android, i entered to the sleep option; i saw sleep time: DO NOT SLEP - 1 DAY DELAYED - 2 DAYS DELAYED - 3 DAYS DELAYED!
i choosed the DO NOT SLEEP mode, and i saw its working but im not sure if it working correctly or not!
Because the meaning say's: DO NOT SLEEP, it mean the car android will still 'ON' forever
this should help to power on on start.
Code:
fastboot oem off-mode-charge 0
for shutdown you can use Macrodroid.

Please can you explain more?
The android head unit is not rooted.
How to run the command?
I want for every key off, the android restarted automatically, i dont need it to keep sync. The last data time.
Macrodroid is just one of these automation apps, just do a research.

Thanks for your reply,
But how the 'Macrodroid' helps me to turn off the android for every engine off' ?
1) But the problem, i think the macro app cannot detect the key if it turned the engine or not !
2) You forget that if i turn on the key , the optical wires also will stop working , (and here the head unit will be turned off automatically because there is no light into the car)
of course you need power line of clamp 15
