Is There Good Unlock App To Replace Pressing Power Button?

Hey guys I have been searching for an app to replace the need to press the power button up top in order to get the screen activated so that I can start using my phone once the screen powers off.


I am hoping there is some kind of app that can do this just by changing the way the phone is held like if its accellerometer changes by a certain number of degrees or something like that.

Thanks!
 
I would like the ability to press any of the bottom keys to bring up the unlock screen, then I could swipe. I know they are afraid that it will constantly be hit in the pocket, turning on the lit screen and using battery, but that is a small price to pay for not having to find that little button on top.

Yea and have the screen be on a 10 second timer, so if it was an accident then it just goes off in 10 seconds not wasting much battery at all.

Maybe its out there and we just are not looking hard enough. It seems like many people would want something like this.

Yea this I use and can do it well on my pattern with one hand its just that stupid power button up top that is hounding me :)

Yeah, wasn't meant to be a solution for your issue, just the guy who was asking for a "password".

I usually use my left hand to unlock the phone, so an app to use the camera button would be awesome. Click it with my pinky, unlock with the thumb.

Still, it's not too bad now, either. I just gotta reach my pointer finger up a little to hit the unlock button.

My hand isn't used to reaching out to hit the power button yet! LOL. Yeah I know about the patern setting; it was cool for couple of days but I rather just enter a pass code AND have a limitted attempt before it goes to wipe mode.

I vote for not hitting the power button too. I am doing some google searches and will post if I find a solution.

Guys -- the 'app' you're hankering for will never exist because it's a technical limitation of the touchscreen.

The electronics that sense touch on the capacitive-touchscreen needs power in order to work (as does the backlight of the LCD) -- that's a huge no no for long standby battery life. That's why a PHYSICAL switch is necessary -- pressing the switch physically causes an interrupt to the processor to wake it out of slumber, without drawing down the battery when not pressed.

Somebody CAN write an app that will prevent the phone from ever going to sleep/suspend, but good luck with getting a day's worth of usage out of the phone!

wypoon couldn't someone in theory write an app that woke the phone up when the phone was shook or turned a certain way though? i personally don't mind unlocking it and stuff but this seems feasible.

Check out the following to see what's possible using the tilt sensor:

Screebl

NOTICE that when the app puts your phone into "hibernation" (i.e. sleep/suspend), you'll still need to press the power button to get it out.

The key to understanding this limitation is that 'sleep' mode for a processor means that the clock is disabled. This puts the processor in a very low-power state. The downside of this mode is that the processor does not execute ANY instructions. Thus, whatever app you install, that app will not be 'running' -- it may be in the memory, but the processor isn't going out to fetch its instructions.

The following analogies may illustrate this point better:

On your notebook -- what is the difference in behavior between screensaver mode vs suspend mode? In screensaver mode, you can touch your (capacitive) touchpad and it'll get out of screensaver mode. In suspend mode, you have to press a physical button. On a phone, 'Screensaver' mode is akin to running an app that prevents the phone from ever sleeping (it may turn off the LCD to conserve some power), while 'Suspend' mode is what is happening now to your phone when the inactivity timer timesout.

im not gonna say you are wrong cause i don't have all the facts, but in regards to you saying nothing can execute while it's locked is wrong. just start to load a webpage and then hit the lock button. wait 10 seconds......turn it back on and bam the page has continued to load while it was off.

You are correct -- an application can elect to run as a background service. When this happens, the clock to the CPU is not stalled, even though the LCD may be turned off. The MP3 application works like that. Downside is increased power consumption while the background service is continually being serviced.

What are you even talking about. You aren't making much sense sorry. Why do I care how much battery life I have when I work from home and am at my desk 12 hours a day, next to my charger?

As you say "interrupt the processor", I want to do just that, but without having to annoyingly touch this top button.

There should be default options for this even.
