Problem:
Solar powered Remote cameras,
Mesh network projects,
Time-lapse projects,
^ just some projects needing a reliable phone
Idea for solution, but how to Implement?
- power cycle the phone at set intervals. Then if the phone has crashed then at least it will become available again without having
- pulling the power from the battery isn't too hard, especially with a removable battery... But...
-pressing the power button is more difficult
So:
- can we alter the boot animation to force into a normal boot up procedure after a set period of time? This action alone would allow greater automation
Where can I find more info on this? My guess would be non Chinese Google / Samsung / nexus phones would be a better choice for cheap phones to try this in as they are better documented

How exactly do you power down a Universal other than removing the battery? The "power" button only dims or switches off the display. Is there a way to make it really switch off the device?
PDA's running Windows Mobile are not designed to be powered off.
You can turn off all radio (wireless, GSM, BT), you can turn off the screen, but you can't actually turn off the device itself.
This is to keep your tasks and calendar running, otherwise it wouldn't make sense, as you could forget to turn on your device to be altered to a scheduled event.
But yes, it can be a pain. In my case, I own several phones running Windows Mobile and what I do is to periodically recharge them.
Failing to do so could in my opinion harm the built-in battery designed to keep essential data alive, when you swap your battery.
If you want to store your device for a long period (months or years), you should consider removing the main battery. Still you can suffer from a leaking internal battery. Don't quote me on this, though.
I prefer to recharge unused devices every month at least.

Incorrect. PDAs running WM can be switched off
and you can turn the entire device off. There are ROMs that include the power off option that will turn the device off completely. I think the proggie is called PC Shut Off, have to find the exact name. I have the shut off function on my Elf and Wizard shuts off just fine. You get a warning that you may lose any unsaved info etc.
For longer storage options take the battery out.
Who wants to turn off their Uni!!!?
I have never turned off in 4 years, never!
If I dont want to recieve a call: Ignore
If I dont wanna hear sound: mute
If I dont want to have any comms on: I turn it off
Just my opinion...
Powering down the Universal
I have owned and still own several WM devices. The Uni remains the only one I cannot power down. When you press and hold the power button on the Touch Pro, it powers down after a prompt. The same with Advantage, and the TyTN 2, all of which I still own. Indeed, the Uni is the only WM device I have used (and still use) which uses what should be the power-down function to dim the display - a totally useless function in my view!
By the way, on many flights, you are told to completely switch off all electronic devices - not just put them on "flight" mode, during take-off and landing. With a Uni, how do you comply?

I simply turn off all comms and push the off button! that´s it
And any plane has going down doing this, and I travel a lot!
Nothing happens believe me

@enigma1nz I think you mean psShutXP. I tested it. When I use the option "Turn off" the device is in normal "sleep-mode".

Many of us know that these days planes do not crash because there is a mobile phone that is not switched off. But I am talking about compliance with instructions. I still believe it is a design flaw in the Universal. I have been hoping someone would cook a ROM that makes the power button to really power down, but it seems none as yet.
Earlier devices doesn't support complete power off because of the HW design. But you can do it in latest devices.
Just think about the power supply model of AT and ATX PC's...
Hello Gentelmen,
I am rather new to android dev but seassoned in linux, i decided to convert my old phone (samsung admire) into an in dash computer.
I am using two basic applications:
* Torque OBD2 Connector: This connects to the car's OBD2 Port, reads the computer and displays information on screen (like HP, Torque, Manifold Pressure and temp, Boost ...... )
* Autoguard Blackbox: This app acts as a CCTV recorder taping my driving and saves it in case of accident so i can have video evidence.
I have modified the andoid system to open both applications on boot and on external power and to kill them when external power has been disconected. Also when external power is disconected phone will wait 5 minutes then go to sleep. (yes i realize there are apps for that but i like shellscript)
This means that when the key is turned and the car is on recording automatically begins and my gauges come up, when the car is off they close AND STOP RECORDING and go away without any kind of interaction on my part.
The problem: Whenever the car turns back on, external power is connected and i would like to have the phone do a full boot so that my scripts kick in,however instead it goes into charge only mode where it boots in to some kind of "hybernation state" that only displays the battery charge in the middle of the screen.
I would like to bypass this and have the phone do a full boot whenever the power is connected.
I have searched for weeks and have found nothing but people withthe same problem and solutions that involve harware and wiring and soidering however this is not an option for me because the phoen is exposed (not actualy insidethe dashboard)
I am not afraid to compile a custom rom and have it run on the phone ... the phoen is solely for the propose of having the dashboard display. (i dont use it for calling)
Could you guys point me in the right direction?
Thanks in advance.

This is the FIRST App that provides (with your phone OFF) functionality to *boot* your phone (and also charge) when receives electric signal (charger or USB)!!MOD Edit: Links removed
This App is useful for:
- Devices to be connected 24/7 non-stop! if electricity goes and comes back it will start device automatically
- Industrial devices working with PIC boards and subsystems with start-up Apps
- Devices that are meant to be stucked in your car or... you just want to swich ON your phone when plug in charger or USB cable
- If your phone's ON/OFF button is broken
*You can revert previous configuration! interface is only an ON/OFF button :=) *
Please, watch explanatory video: http://www.youtube.com/watch?v=QYDk_qPpTVo
READ compatibility:
- Your phone needs to be rooted!
- Only tested under *Samsung* devices! may don't work in others!
Mod Edit: more removed.
Thank you~
Sounds promising however it's Wwwaaayyyyy... too expensive for a 107kb app that only does one thing (idevices come to mind).
Power off when the power is disconnected would also be a good option to have, or power off after 5 minutes off power loss. Especially when the device is used in a vehicle etc.
Very nice thought! Looks promising!
Hi,
hoping someone can give some advice as I'm running out of ideas. Essentially what happens is that my Desire S powers off whilst I am using it, mostly whilst I am navigating through the phone or using any kind of App (not always immediately, but always after a few minutes). I can power it up again afterwards but it will not boot up all the way & instead powers off again. However, if I connect it to a power source it will power up all the way again and it also doesn't power off whilst I use it and it is connected to a cable power source. So far I have:
- Bought a new battery
- Placed folded paper on battery
- Done a Factory reset (everything is stock, phone hasn't been rooted)
Through all of this the problem has continued. Another weird thing that has been happening whilst all this is going on is that the phone seems to have issues keeping the date & time synced. It sets the date to some day in 1980 & time is also incorrect. I have to manually set the date & time as it doesn't correct itself over time.
Any help or suggestions would be much appreciated.
I find it incredible that for a phone with a non-removable battery that you can turn the device off without having to get past the lock screen security. This is a major security flaw in my opinion.
If you were unable to power down at the lockscreen, then if your phone were to be stolen, then at least you would have the time it takes for the battery to eventually die to attempt to track it.
A long-press of the power button at the lockscreen should only be allowed if the lockscreen type is set to none/swipe.
If anyone is in a position to put in requests to Samsung themselves, could you please submit this.
Any further thoughts welcome....
What if you're stuck on your lockscreen, your screen doesn't respond and you have to reboot your phone to solve the problem ? how are you supposed to do if this option is removed ?
Terrible idea you have here
And if there was no way to turn it off from the lockscreen, the stealers would just have to wait until the phone have no battery left, then the phone would be off

A long-long press of the power button (approx 8 seconds) will force a reboot as per all Samsung phones, so if you do have a problem you can then go into recovery (eg. to wipe cache etc.). Ok, the thief might also be aware of this and do a factory reset in recovery straight away, or even keep the phone in recovery until the battery dies, but some may not be aware to do this. And, even if a thief did a reset, then at least your data would be wiped, which is half the battle when a phone is stolen.

But at least you would have the time it takes for the battery to die to track it, which I already stated. So once stolen, you could have anything up to a day to find it again. Currently if someone steals your phone, all they need to do is switch it off immediately, and you will have no chance of ever seeing it again.
A nice firmware feature would also be to send an e-mail to yourself of the phone's current location when battery level reaches a low level (eg. 5%). Some apps (eg. Lookout) have the facility to do this.
As the S7 has a non-removable battery, it should at least have the option to disable the power key menu at a secure lockscreen.
All phones with non removable batteries are like this for the reasons the person stated above. This function is exactly the same as if the phone has a removable battery. If a thief stole an s5 they could just take the battery out immediately and you couldn't track it either... The battery isn't a security feature. It's just to power the phone. They need to have a way to cut the power on devices. This is standard for most electronics. Hold the power button on your laptop and see what happens.

Don't know if you are aware but if you setup and use Samsung's Find My Mobile, you can lock, disable shutdown, and display a message on the screen with a button to call a number of your choice should you lose the phone. Try it out.

Considering the fact that should your device become unresponsive/problematic you can always fall back on a long-long press of the power button at any time, including at the lockscreen, in order to reboot / go into recovery (which is an inherent hardware feature across all Samsung phones), I therefore still believe that allowing a power off at a normal long press at a secured lockscreen prior to passing the lockscreen's checks represents a flaw in your device's security. I think power off (but not reboot) should be omitted at the lockscreen popup and only included when a longpress of the power button is done after the device has been unlocked.
And what makes it worse, you can also pull down the quick panel shortcuts at the lockscreen which would enable a theif to turn off location from there too.
Basically, find my phone type functions are only of any use only if your phone is ever lost, but useless if ever stolen.

It does seem that Samsung have missed a trick with shutdown from the lock screen that could be very simply enacted and give another string to the security bow.
or you can just disable power menu on lockscreen via Gravity box..viola ?

You seem to be missing the whole point. Every phone behaves this way. Whether a removable battery or not. You can disable the power to every fun from every manufacturer at any time no matter what type of battery. It's not a security flaw. Also you can go into settings and disable the notifications from being pulled down before the device is unlocked.

They should make phones with no batteries to fix the battery flaw, powered by air. Working in this field, I've seen a lot of broken and stolen phones come and go, if you really want to remove the battery, it'd take 2 minutes max if you arent worrying about replacing a 10 dollar back glass.
People consider iPhone's battery non-removable too, you can get that thing disconnected in less than a minute. Also there are dongle tools (Can even DIY one) that can force your phone into recovery/download mode simply by plugging it in.
So I think this is just needless worrying.
