I have a g1 that is about 3 years old or so, and I am having a problem. When the phone is booted up and the screen is off, pressing the power button will turn the screen on, but the back light is off and the phone is unresponsive. If I lock the phone again and unlock it by pushing up the keyboard, the backlight works and the screen works too. If I slide the keyboard down, the back light goes and phone becomes unresponsive. The only way to get the backlight back on is to lock the phone, and unlock it by sliding up the keyboard. I realized that when the back light is off and the phone seems unresponsive (keyboard closed), the touches and button presses are actually recorded, because when I slide the keyboard up, the presses and touches are carried out as they were put in (even though the back light stays off). This has been happening for a few months now. Any ideas?

Just got the diamond2 and am loving it. Came from the touch pro. Problem is I have been pocket dialing while its in my leather case. This is not good, as I am a real estate salesperson and it is calling some important people. Does anyone have a solution? BTW, I was using touch lock pro on the touch pro.
Thanks!
hi lorettaboy
you should lock the kets by holding the end call button for a few seconds and that should sort your problem out
I forget what it's called but there is this locking software that will completely lock the phone if you rotate it around the long axis one way and unlock if you do the same the other way.
I have been using throttle lock though. It is like the Android unlock screen where you draw patterns.
If u press the power on/off button for a second, the screen goes off.....isnt it ok to avoid your problem?

I think what may be happening is that the power button is being pressed while in the case unlocking the phone and keys. I had this happen before and still does sometimes when in my pocket.
4 characters: S2U2
Hoping wm6.5 features a lock that's as functional as S2U2.
I personally use http://pocketshield.netserver01.com/ It locks your phone when its closed, and you have different ways to 'wake' it. the 3 that I set it currently is:
1. if the phone is in the case (aka dark) it will not unlock even if phone is ringing, but once you remove it from the sleeve/pouch it will be unlocked.
2. If its night time and the above prevents you from unlocking in the night, shaking phone left to right once will unlock it
3. lastly if I take out stylus it will unlock.

Googled it, light sensor lock sounded interesting, tested it. Never got the light sensor unlock to work. Had to keep tapping the lock button for a varying number of times to unlock. But worse: got catch-22-ed twice within ten minutes.
The first time I got caught with the screen on, the 'turn off' dialog active, and Touch lock Pro active but not clickable because of the turn off dialog. No way to unlock the device and the power button was hijacked by Touch Lock Pro. Removed back cover, took out battery and restarted.
The second time the device locked with the screen off, and the power button couldn't turn the screen on again. No way to find out what happened this time. Removed back cover, took out battery and restarted.
This tool is possibly the least compatible tool with the TD2 you will ever find
I recently bought a used Nexus One, but it's in great shape. It was preloaded with CM 6.0 RC1, so I decided to update it to stable CM 6.1.1.
I love the phone and CM, but there seems to be an issue whenever waking up the phone from sleep.
If I have the phone on a perfectly even surface (table, etc.), wake up and unlock the phone, it will sometimes wake up with the screen orientation in landscape mode instead of portrait. This even occurs when I lock the screen in portrait mode.
Another issue is when I'm using my phone in bed. When I lay down and hold my phone above my head to browse and stuff, the phone will act very oddly. For example, if I'm in the browser and scrolling up and down with my fingers, it would register as a press on the soft keys. This ONLY occurs when I hold the phone above my head to use the phone (imagine the phone upside down).
Any ideas? There seems to be something loose in the phone. I searched the forums and people guess that the accelerometer is loose, but it's normal.
I have this too. My phone is unusable if its flat, i.e if it's layed down on a table. If i do this the screen barely responds at all to touch.
Anyone else having this issue? It's pretty annoying!
So on Monday I went out and got a shiny new Turbo. I'm loving it so far and hoping for root and or bootloader unlock eventually. This morning though something odd happened. For a period of about ten seconds my capacitive buttons quit working completely - no vibrate when I touched them, no nothing. The phone wasn't frozen or anything. Then they suddenly started working again. About five minutes later it did it again, but it hasn't done it since. Should I be worried? What should I do?
I'm having the exact same issue, seems to be random.
Ok I have the Moto Maxx and noticed that too... then I figured that in my case it happened because I was touching the screen with my palm while tying to reach for the capacitive buttons. The buttons stop working while you are touching the screen. Check if that is what is happening to you.

I've even had it do that if there is any liquid on the screen...like maybe a few small drops of water after you just washed your hands or something like that.
Does the proximity sensor disable the buttons? Thinking that if the phone thinks it is near your face for a call, it might shut off the screen and buttons to prevent accidental presses.

They will automatically dim and turn off when in a well lit area/room. If you are in a dark environment they will always be on.
Just hold the device under a lamp and watch buttons dim slowly off. Turn lamp off or go to a dark room and watch them illuminate back to life after 8-10 seconds.
Pretty standard, however, if they are going on and off constantly in the dark, than most likely a defective unit.

I'm pretty sure this is what happened to me, after playing around with it I noticed my phone does the same thing. That's a load off my chest, I was a bit worried about it. thanks!
Screen pinning vs Long press for menu
Just a note, I recently discovered that if you have lollipop screen pinning enabled under the security settings and also the "Use long press for menu" setting enabled under display settings, they seem to conflict and cause all kinds of key lag with any of the capacitive keys. Must be because both utilize a long press of the recents/overview key. As long as you only enable one or the other it should be fine. Just thought I'd throw that out there.
I have had this problem too, it simply has to do with the fact that the screen is and capacitive keys are combined. You can use one or other, but not both. If you encounter this, just mess around on the screen for a few seconds and the keys should work again.
Clear cache. That usually fixed the problem for me.

This has just started today. When I switch the screen on after the phones in standby it opens on the Google now screen.
So I one click the power button, the screen goes off, leave it for a bit one click the power button and the screen lights up on Google now rather than my home screen.
Any ideas what I've done to upset it?
No one else having the problem? I find when I close the double dip flip lid it presses the home button rather than shutting off the screen. Amazingly the lid just has to hover above the home button for it to open Google and the screen goes off as and when as I have it on auto timeout.
Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.
