automatic screen shut off - G2 Q&A, Help & Troubleshooting

So I've browsed around and there are plenty of screen issues, but I haven't seen the one I'm experiencing nor have I seen a solution. When I press the power button my screen comes on and turns off right away. Sometimes a few seconds after I hit the power button sometimes even longer. Most times I won't even be able to put in my security pin to unlock the phone. I see people saying Verizon will do an update soon but that isn't good enough considering I can't use the phone. I did find a loop hole to this problem. Quick start the camera with the volume down button then press the home button after the camera loads and it won't shut off by itself. I thought I'd post this method up for others having this frustration.
If this particular problem has been discussed and beaten to death then the mods can close the thread.
I've got a YouTube link but I don't have 10 posts to show you. Search for user name "vfreeza" and it is the only video I've uploaded. You'll see my first time turning the screen on was using the quick camera method and the times after is with just the power button. The screen turns off without even my hand touching the phone.

don't cover the sensor on the upper left hand side

Yup I read that too. My fingers rest at the corners of the phone and I've tried the not cover sensor thing as well, makes no difference.

Wish I could disable the sensor. I hate this problem

Just a quick update. I bought a Diztronic tpu case and the moment I put it on all the problems went away. Screen acted nornal and knock works. My guess is without the case my hand is making some kind of connection it shouldn't be when I'm holding it without a case.

Did your old case hug the bezels tight? because it tends to mess with the digitizer perhaps the incipio feather case? or a plastic case of some sort? just curious im pretty sure that was your problem cause if you barely press on the screen youll notice waves in the lcd screen and since the bezels are so small on this device some cases can do that.

thats extremely odd but im glad you got it fixed!

Thanks! This case is never coming off! haha

My phone has that very problem and it's driving me insane.. i love this phone, but it truly is a hassel to use it after its been idle for awhile.. or at night... hands no where near the sensor or anything, it could be laying straight up or down n itll still have that problem.. thanks for reading.
I normally just wipe the sensor area, n it magically starts working again.. n i don't touch it, n the problem comes back after awhile....
Also naked phone besides screen protector, but it's not covering up the sensor.

My phone does the same thing. It's so ****ing annoying.

Smart use of Proximity sensor can kill the need for the lock screen

The main need for the lock screen is in the following situation:
Phone is in your pocket (or bag), a hard key is accidentally pressed, the device wakes up. This by itself is not a problem, since without anything else happening the device will go back to sleep, but, if another hard key is pressed while the device is active (screen press can not happen while in pocket, since it's capacitive), the device can start do annoying things.
Now, if the proximity sensor can be designed to switch on when device wakes up, and put it back to sleep (immediately) if device is in pocket/bag, this will kill the need for a lock screen. This is totally possible and just awaits the programmer who wants to make our lives easier...
hm. try pocketShield?
it locks and unlocks your device by use of the light sensor.
Interesting. I will use it for now.
The problem with using a light sensor is that if you use the phone in the dark it won't unlock. Proximity sensor won't have this problem hence it's a better sensor for the task.
Apparently this will happen even without the help of the XDA community...
I've just sent the following email to PocketShield:
Hi,
I would like to know if you are working to utilize the HD2's proximity sensor for unlock (like you did for Omnia). If so, when should we expect a version with this feature ?
Thank you very much.

This is their answer:
That’s the idea, but can’t confirm that yet because we are not sure if hooking into the proximity sensor will be possible. Hope yes, as in Omnia2. Just received our new HD2 today and will start to dive into it next week.
Best Regards,
Jim

Use TouchLockPro. It has both light and proximity sensor and it is free.

won't this increase battery drain dramaticly? i think it will becouse it will be constantly looking for light and using that proximity sensor..

You are wrong about one important detail though. The screen is very sensitive and can easily be pressed through the lining of your pocket, and even through fairly thick fabric like jeans.
it's a capacative screen...
capacative scree = no stylus/fingernail/penny/spoon
it wont be acvitating throught screen contact.
impossible. (unless you have rrrrrealy thin pants, and the current can pass throught them)

hi, the pants didnt have to be that thin. i think the hd2 screens also vary a lot, in being more or less sensitive. another thing is that people are deifferent when it cames to electric fields. also sweating can affect the display. i startet programs and other touchscreen things already, when the device was in my pocket.

In the case of Pocketshield, it won't. Because all sensors only turn on during a short period of time (seconds). Once you unlock or turn off, sensors go to sleep. This is one of the reasons why "auto lock" is not possible, because that will indeed involve a permanent monitoring on the sensors.

You don't know what you're talking about. I didn't say it was sensitive to pressure, but rather that direct contact between skin and the screen is not necessary. Holding my finger on one side of the fabric, and the other side of the fabric touching the screen, this is registered by the screen as a touch EVERY TIME. There are maybe materials that completely isolates the screen, for other materials it probably depends on how thick they are. For me it is certainly possible to influence the screen even through pretty thick cotton fabric (maybe other types of fabric too, I wear mostly cotton), leather, and even paper. Just to test it, I just did a slide to unlock my HD2 through a pile of papers (granted it wasn't a very thick pile, only six sheets of paper thick), and through my leather shoes (this was a little trickier, I had to to make sure that my foot made good contact with the leather at the point where I was sliding my phone across the shoe). i can interact with the screen through normal denim jeans fabric without any problem, and the pocket lining of trousers are usually quite thin, so accidental interaction with the screen seems almost unavoidable if the screen is unlocked in the pocket.
I have actually had some problems a couple of times when the slide to unlock had been deactivated on my HD2. I once took my phone out of my pocket and it was at the confirmation screen for factory reset, and I have actually had the phone hard reset on me once which I suspect may have been caused by the slide to unlock being deactivated. I would never knowingly put an unlocked phone in my pocket, and I wouldn't recommend it to anyone, but you're welcome to do as you please.

oh, i didn't know it was that sensitive, then, i can really see a need for an apps like this.
but, what about just a normal case? slip it in and out? i mean, i think that COULD solve your problem in a 'no thrills' sorta way... but it wouldnt be as exciting now would it?

Attention with clicking screen and dust under it !!!

Hello,
I got my N1 1 week before, and i'm really satisfied with this phone.
Since the first day that i got it, i tested it by applying pressure to the corners of the screen, just to check if it had any problems of clicking screen like the other users reported, and it was ok, no clicking and everything normal.
But today, i tested it again and i noticed that it clicked near the touch buttons at the bottom of the screen I applied pressure on it, and it seemed like it glued again and didn't click anymore, after several hours it begun to click again
I think i will apply the hairdryer method, before dust goes under my screen.
I just opened this thread to warn the other N1 owners, to check their phone again, so you are all sure that you have no problems with your screen.
Best Regards!
What's with this clicking?! I don't understand where you see the problem
Thats a good point cause I just got the N1 couple of days ago and noticed a clicking sound on the top area. Didn't know this was a known issue. Gonna have to look into it further.
I tried telling you guys in the thread I started (the other one about the dust under the screen), where I first suggested using a hairdryer... that everyone should go ahead and warm up the screen and make sure it's sealed properly. The glue has to be warmed up well to really get tacky so when it cools it will stay sealed since it's porous.

Yeah I did something like that. When I was leaving work I figured if I crank up the heat all the way up and hold the phone in front of the vent it might achieve the same thing and it seems like its good now. I don't here any clicking any more. I actually realized it was clicking from the bottom area as well aside from the top but it seems good (hopefully).
What exactly do you guys do to get that clicking sound? You press the edges of the screen? Applying a lot of pressure, or the usual? I don't seem to be getting anything weird, but I'm not pressing too much either.
You have to press at the corners with a good deal of pressure to hear the clicking.
Hm, I don't seem to be getting any noise. Is it loud, or barely noticeable?
Also, if I start to hear it in the future, is it an indicator that I might get the dust problem? Should I heat it with a hair drier? Won't that melt the plastic parts of the phone?
Press hard then let go and you may hear a very faint click. You have to listen for it. If you hear nothing then I guess your unit is fine.
Hairdryers shouldn't melt the plastic components, but should be hot enough to warm the adhesive up.

Ah, sounds like breaking the glue under the screen or something..
I used the hairdryer and it seems to work for a short time on the 4 softkeys.
Will try the upper part now
Did the hairdryer thing a month ago and its still holding strong
This message was deleted by its author
I am having trouble with this, after reading this thread I noticed the 2 bottom corners of my screen do click when pressing down on them hard, so took out the hair dryer and did each corner for about 2 min on full heat full blast, screen was hot to the touch, applied firm pressure while it was cooling afterwards, and there was no clicking at that time.
Now afew minutes after it is still clicking.
How did you guys do it exacly?
edit: nvm got it, had to hold down harder and right at the edge of the screen.
Yeah Mafi0s0, thats what i did too. I realised my screen clicking again after doing it the first time. Doing it the second time - it required alot of pressure, but doesn't seem to clicking anymore.
Thanx for the tips guys, I also had the same problem, but applying more pressure fixed the thing.
Mine also had the clicking at the bottom, and i have some dust under the screen.
It fiexed for now .. but i will probably disassemble it to clean all the dust if it gets worst.
This hair dryer method hasnt worked for me at all, I have tried 3 times, I just checked then and the clicking is heaps bad, its very loud. I am gonna get dust under my screen for sure if I dont fix this.
How have you guys who have been successful done it exactly?
Today I noticed 2 very small dust particles under my screen. After seeing this thread I did the corner test and it turns out the the bottom right of my screen clicks. I did the hair dryer trick and it seems to have fixed it.

3 protruding buttons cause battery drain too.. need a case to deal with this

I carry my phone around in my trouser pocket in one of these.
http://cgi.ebay.co.uk/BLACK-LEATHER..._MobilePhonesCasesPouches&hash=item483990906e
I am always on the move with the phone in my trousers and I am sure that the buttons get pressed all day long causing the phone causing the screen to switch on. I find that with my screen off all day over the weekend, the phone lasts about 16 hours without charge (which is pretty **** anyways) but when I am out, it lasts about 8 to 9 hours max.
Does anyone else experience this?
nope i dont experience this
its more likely caused by your phone going in and out of high/low/3g/3g areas while its in your pocket. the buttons are quite hard to press accidentally imo
Apart from the top power button, it's only the middle button that wakes up the device. I have a gel case on mine (not that ugly ass full silicone wraparound crap) and the edges protrude a lot further than the buttons, so I don't seem to have this problem either.
I believe I have also had this issue. I haven't tested it via battery life, but I do sometimes pull my phone out of my pocket to see the screen on.
Additionally, I downloaded a no-lock app from the market, and whenever I went out and had the screen lock disabled, I'd pull my phone out and it would be doing something (using calculator for example). I've since, re-enabled the screen lock
Wish we could disable the menu button from turning the screen on.

I have this exact kind, 4 different colours.
Just a random eBay ad to show you what it looks like.
The lighting is a bit bright making them look a bit more glowy then they actually are in this auction.

They have terrific grip in your hands and protect the device face down, face up and from any edge impacts. Call it the cheapest insurance policy you can ever have. I have a black x10 and got clear, smoke, blue and red ones. They all look really nice on the device.

Front screen only GLUED on? It is popping off!

Okay, I read that someone lifted part off the front by removing a screen saver! Now with me, I recognized that on the left side bottom, left to where the slideview and call buttons are under, the ENTIRE part seems to come up.
It is lifting itself and I bet in a few days/weeks this will get off.
So my question is if anybody had this happen and knows what is under there? Is there a possibility to GLUE it back on?
Now since I am watching this, I think the ENTIRE front can come off eventually and if it is just glued on at the bottom where one has to press the buttons all the time, it is only a matter of (short!) time until this gets out of hand.
Anybody found anything about taking this phone apart yet?
That happens to my phone, I do not bring it back because I buy it in a duty free shop here it japan and also that is the only issues on my phone and only some bugs. I just press it always there to bring it down but it keeps popping up. I think i can glue it, so I do it to fix the problem. Just be carefull if you do it, I notice that under the plastic screen there are buttons (as I think it is) the hard part that you feel when pressing the slideview or call. When you use a liquid glue and put to much, it can go to that button and worst may stuck that part or go inside the phone and also the part where the mic is. I put glue just on the sides just make sure to put small amount at a time. I cannot give the brand of the glue that I use because its in japanese.Now only the small part in the call buttons is up a little because I cannot put enough glue on that part, but in the slide view button its now okay and working well.
This is my firts post on xda hope it helps a little.

[Q] Capacitive button tester

Is there a tool that can test/adjust the sensitivity of the Epic's capacitive buttons? Mine seem unresponsive and I'd love to know if the hardware is not sensitive or the software is ignoring the taps.
Something that displays a readout showing which button is being pushed would be really useful.
Thanks,
Jason
there really isnt. its being classified as a hardware issue. i swapped the board out on mine the other day with a returned phone and it started working. taking the phone apart to fix the button at the bottom is a complete pain in the face. and if the gorilla glass faceplate comes out (which needs to happen to swap out the buttons) then it never really goes in correctly. nor does it stay stuck.take it back to sprint and see if you can do a 30 day exchange on it.
Thanks. I got mine at Best Buy and have their insurance. They'll fix/replace it for free but they have to send it to their service center and give me a loaner. I almost replaced it within the 30 days but when I took off the screen protector (Skinomi) to give it back, the keys were working great. I decided to hold on to the phone. Now I have another protector on it (Realook) and am having the same problem. I'm assuming the button is less sensitive than it should be so it works fine without the protector but not well with it. I might have to switch to a partial-screen protector.
So if my buttons are very difficult to press then its an issue and not the general design of the phone itself?
My wife said she has no problems with the buttons so I'm going to have to compare hers to mine.

Same exact situation. I was using the Realook screen protector and everything worked fine except for the back button. After I took it off I noticed that the back button worked just fine. After using it a little longer I still feel like it's not as responsive as the other three buttons.

There's a couple of ways you could do this:
Every time you press a capacitive button, it should blink right after it registers. This indicates it was pressed.
Another way is to boot into Clockwork Recovery Mode, goto Advanced, and use the key/button test option that's in there.
I'm also using a Realook screen protector, so far it's the best I've tried. I've used Zagg, Invisishield, StealthGuard, and Amzer protectors and non of them had the clarity or feel of the Realook. It feels and looks like nothing is there, aside from being an oil magnet. Anyhow, I don't have any reduced sensitivity when using it compared to bare.
One trick I use to apply the Realook is cover the whole phone with 4 or 5 strips of scotch tape (overlapping each other) before application, it helps to get rid of all the super fine dust particles that are floating around. Also, use a high power flashlight, and shine its beam across the surface of the screen, it will make all the dust you couldn't see before light up. Have a few looped pieces of scotch tape ready to pluck off dust particles that get stuck on the protector and screen. Then get the Realook protector ready, pull your strips of scotch tape as one from the top and quickly align the protector, pull more tape off and follow with the protector, this insures no dust thats floating around will get on your screen or protector, if some does, you have the flashlight to easily show you and the tape at the ready to pluck them off.
Reason I said the above is because you might have minute dust particles that are creating a gap with just enough space to prevent your capacitive buttons from registering.
I took drastic measures and cut a rectangle hole out of the Realook protector so I could have direct access to the buttons. It is ugly, but it works. The back button works much better now.
