Can't turn display with HOME

Can't turn on display on Samsung GT5570OI with GB 2.3.6 and enter to unlock mode.
When mobile screen is in standby and I press HOME button nothing happens. I need to press POWER button to show UNLOCK on screen, then I simply unlock the screen with drag.
How to setup that my HOME button working the same way as POWER?
How to show UNLOCK screen with HOME button?
This normally works (HOME and POWER buttons) on my Sasmung Galaxy S and Galaxy 3 model, but can't figure it out how to setup this on Mini.
Thank you.
u hav to remap the wakelocks in keylayout. This feature is not present in GB i think. So to use this feature, flash a custom rom like CM or stock

Screen not working?

Turned my phone on today to find the touch screen is not working. The exterior lock button wakes the screen up but I cannot enter my pin to unlock the phone and touching emergency call etc does not do anything. I have tried turning the phone off and on by holding the power button (as I can't select any of the options when I try to turn it off). Has anyone experienced this or a similar problem and knows how to fix it?

If you keep the power button pressed it will reboot. If you hold power and vol up it will boot into recovery from there you should be able to factory reset. That said if you don't know what your doing it won't help and if the touch screen has become disconneced it also won't help.

Smart Lock disable swipe to unlock

on my older phones (xperia xz1) there was an option to disable the lockscreen at all if the device is unlocked by the smartlock. this way i only need to press the powerbutton to get to the homescreen.
was i could not find any settings or apps: anyone knows a way to disable the lockscreen while smartlock has the device unlocked?

I have a Note 9 (SM-N960F) model.
Stock Firmware, no root.
Using Nova Prime launcher.
I have Fingerprint unlock and Smart lock enabled.
If i pick my phone up from sleep (locked)
i either press/swipe down
where my Home button (not visible) should be and phone goes directly to Homescreen.
Otherwise, i use Fingerprint unlockfrom "sleep" directly to home screen.
No need to press power button.
I'm sure this is better options.?
Only if you reboot phone or randomly sometimes (it's a security measure) I have to manually unlock.
This is the exact problem
Of your phone is already unlocked you still need to swipe up. I don't want to see any lockscreens at all. Why is this even implemented this way.
What I want is being able to use the phone without any unnecessary swiping after pressing the power button. (Razer phone 2 and Sony had an option for this)

i think you misunderstood my point.
I was trying to describe my button press action.
You don't actually swipe nothing.
You don't see the lockscreen, at all.
Call it press etc,
where the home button is.
It unlocks to Desktop.
You don't see the lockscreen at all.
From device sleep,
i "press " Home button
and device goes straight to Desktop.
Fingerprint it's the same. It goes straight to the Desktop.,
( You don't see a lockscreen)
Good luck
Yeah i got it
But that's the problem: you still need to swipe up the lockscreens if you try to unlock by the power button. Unlocking via Iris or fingerprint or pressing the invisible home button world great and you skip the lockscreens completely. But after pressing the power button the is 1 more action that is needed.
On the screenshot you can see (in German) "unlocked by smart lock" after trying to unlock with the power button

dont use the power button.
use the finger print or home button in conjunction with smart lock policy.
you'll get better milage off of the power button this way.
Yeah... Don't use the power button...
No sorry not an option ^^
Is one of the reason I don't use it, and also because I don't know the effective range.
But leaving the home button enable requires to let the "screen touch sensor" active so it will inevitably consume more battery am I wrong?
Are you on Oreo or Pie?
On Pie, this works fine for me. I press the power button, it unlocks with intelligent unlock and goes directly to the home screen/last app. No swipe needed. Does the same when I press the hard press home button.
If you're on Oreo, do what bober10113 says.
I am on Pie, and I am constantly getting the lock screen where it says unlocked by smart lock, but I still have to swipe.

Android Pie Screen Lock with On/Off Button and Screen Timeout Lock

Hello Everyvone,
since i've upgraded to EMUI 9 i'm searching the option to disable the screenlock by pressing the on/off button.
Sometimes i disable my screen just for seconds and want to came back without need to unlock it.
Until Android 8 there was an option for this in every Android version. But where can i find this now in Android 9?
Same problem is with Screen Lock by timeout. Normaly after screen timeout i configured 3min where the device was not already locked. So with just pressing on/off i could have came back without unlocking again.
Any ideas how to get this back now?
Yeah the brainiacs at Huawei removed this with the Emui 9 update, it is still possible in stock Android 9 afaik. Now you can't set any time limit or anything, just instant lock when the screen turns off whether it is by pressing the power button or after your chosen time. Really annoying but not surprising. I wonder if this is to force us to use fingerprint unlocking, which I don't use because... Huawei.

Question When I press power button, phone goes to lock screen instead of turning off display

Hi, when i press the power button on my pixel 7, sometimes (i would say 50% of the times) it goes to the lockscreen instead of turning off the display. I cannot figure out why sometimes it does and sometimes it doesn't. Is this an intended behavior or it's a bug? Maybe I've missed some "smart" feature?
It could be the feature "pick up to wake" . So when you are pressing the power button and move the phone at the same time it wakes up again.
Does it also happen when the phone is flat on the table?
To have more control over when the screen turns on, consider these settings
Display:
- Disable wake on plug
- (Other important settings here too)
System->Gestures:
- Disable tap to check phone
- Disable lift to check phone
- Enable long press on fingerprint sensor to unlock phone
- (Also consider changing press and hold power button)
I had this on Android 12 Beta when I changed the animation speed to x0.5
