[Q] any apps to replace power button for screen lock-unlock??

I feel ,there is some issue with power button on my tab7.7 , because when i press power button to on or off screen..Sometimes screen shows like rainbow color scattering ...or yellowish bright dots mark, like sand all over on display with black/blank background .
i have to press power button again to get it back normal..So seems there is a issue with power button or power supply to display.. so to make minimal use of power button.. i am looking for any apps... which replaces power button with volume button for screen on-off(lock-unlock) only..
please help ..i have no much idea about..
thanks in advance.
Lock & Screen Off Widget by fsinib. But there are many others.
im using Smart Screen On Pro version and it works awesome
thank you both guys for the suggestions
Lock & Screen Off Widget by fsinib ,is not what , i am looking for, but Smart Screen On LITE..is what exactly.. i am looking for.. i tried it ..but not satisfied with its response, so i kept looking for another one .. and found TapTap app. .. seems it responses better than Smart Screen On .. but even not 100% accurate, but surely..it reduces almost 90% use of power button..
TapTap doesn't support ICS. However I've found Smart Screen works flawlessly on ICS. (I have a custom ICS rom called QuickSilver)

Replaced screen and now nothing............. plz help

hello to all,
thanks in advance to all that read and try to help me,
replaced complete screen unit - LCD, touch, and outer glass
after replacing the unit and reassembling the phone the LCD will not come on.
what the phone does do is when i press the power button and only the lights under the home, back and menu buttons light up but go off as soon as i let go the power button. if i keep the power button pressed any longer the lights start to blink. when they start blinking they will go off as soon as i let go the power button if i keep the power button pressed long enough the lights go out on their own. after they do i release the power button and within a few seconds the vibrator cycles one time
i plugged the charger in and the red led light came on and stayed on for a good while then turned to green. i press the power button and only the lights under the home, back and menu buttons light up but go off as soon as i let go the power button. if i keep the power button pressed any longer the lights start to blink. when they start blinking they will go off as soon as i let go the power button.
so this where i am right now. please help if you can and thanks again

Moto G(XT1064) issue with Display and getting to bootloader

Hello, My Moto G 2014 has a weird issue. Pressing the power button basically kills and shuts down the display. The display cannot be turned on by pressing the power again.
Turning on the phone also does NOT show the display.
Only way i can see the display again is -
power off the phone.
get to bootloader
select reboot option
Then phone turns on nicely.................... untill i hit the power button again, then display is dead again.
Last couple of days, i'm not even able to get the bootloader. I tried pressing the power + vol buttons but no use.
I cannot use the adb option as i cannot turn on the developer options on the phone without display.
Really appreciate any help. Thanks

My Nexus One screen not working after changing upper motherboard

Hi! Hope all of you are well
My problem is that about the title, I had to change upper motherboard because dead Power and +/- Volume buttons. Between my brother and I did the job, we put all in the same way the old mobo was, the phone charges until charge LED goes green as normal, the new Power button works because when I press it the phone does the typical boot vibration, but screen dead, it doesn't show nothing, even after waiting a few minutes until it fully boots the OS the Home, Menu, Back and Search buttons doesn't vibrate after pressing them
Any help and suggestions will be well received and appreciated
Thanks in advance!
