proximity sensor and an ambient light sensor problem...

I made a few phone calls and I noticed the screen will go off for a few seconds and then go back on and stay on... Why?
It is wasting out my battery this way.

The phone goes off as you bring it close to your ear to stop your ear pushing anything whilst you are on a call then when you pull away the screen will come back on is that what you mean

Lol, no, that's not what I meant.
Supposing I make a phone call, the screen is lit as normal, I then place the phone to my ear to speak, the screen goes off, after 2-3 seconds it will come back on and stay on!
Even if I took the phone away from my ear while talking, and then put it back on my ear, the screen will once again go aff, and after a few seconds it will come back on and stay on until I finish the phone conversation.
Sounds strange but that's exactly what it's doing.

sounds like you got an app controlling screen timeout while on call. check through your apps see if any of them have permission to control screen time out

What app could that be? I do not have many apps but will list what I have...
Barcode Scanner, Color Flashlight, File Manager, Fishing, Yxflash Player, Rock Player, Root Explorer & Uninstaller...

best is to go to menu>settings>applications>manage applications and check through manually. i had a similar issue with my x10 and found it was a app causing the screen to stay on while on a call

I just went through the applications. All I could see was around 50 or more applications, what am I to do or look for in each one, how do I find out which app is causing the screen to stay lit and how to stop it?
Sorry for this, I'm just new to the streak!

No quick way to do this but its most likely an "installed by you" app so try them first

This is EXTREMELY strange because all the apps I have installed were on my previous HTC Hero & HTC Desire and never did either of them give me any problems with the proximity Sensor...

I'm suffering the same problem, I did a hard reset a few days ago and only have handcent, Share price and astrid installed so can't see how its an app causing it.

It's firmware 1.6

Yeah but which build is it 4399 or 3883?

It's build 3883. Yesterday I downloaded the update to 4399, tried to run it several times, it does nothing and just reboots and turns back on...
However, could the proximity problem be a fault as I've never had this problem before and I've had dozens of touch screens in the past...
I will now backup my data and do a factory reset to see if it solves the problem.

Flumps, thanks a billion for your help, seems you was right!
I just did a factory reset to remove all installed apps & settings, when the booted back on, I made a phone call, put it to my ear for about 10 seconds, the display shut off AND STAYED OFF UNTIL I TOOK THE PHONE OFF MY EAR!!!
Strange though, what app could it be?
What I will do now is install the apps again ONE BY ONE to see the culprit, and if I find out I will let you know.

Ok, I just installed all the previous apps I had one by one and testing the phone.
Have a guess WHICH app was the culprit????
The dam Advanced Task Killer!!!
I am not at all surprised though because other people said that task killers are NOT recommended on the Dell Streak.
The only weird thing is that I've used the Advanced task killer on 3 other Android based phones including HTC Hero, HTC HD2 & HTC Desire and I never had this problem...
I take it the Dell Streak does not like task/app killers...

haha, glad you sorted it bro! ya, task managers are abit meh on the streak, best to stay clear for now.

Thanks!

Do you use the app screen standby by nkahnt?
When the message screen standby mode comes my screen goes to the brightest mode instead of beeing shut off.
Any ideas?
Do you have a standard nexus 10 with the latest android version?

Lg g2 sprint variant "Knock on" feature broke

Well. It worked up until about 20 mins ago. Then randomly just stopped working. Ive rebooted, shut down, enabled and disabled the feature in settings. Fixed permissions for the heck of it. Cleaned the screen. Reset calibration, etc. Nothing seems to work. I can double tap to shut the screen off easily, and it works flawlessly, but trying double tap to wake is completely useless. Any suggestions?

Well thats ****ing depressing

Tons of lg users are experiencing this issue. Its a design flaw with a hardware component that easily breaks. Wonderful build quality -_-...right. So only option is replacing the phone. But to how soon, until the other one breaks. So its kinda like. Well. This blows. I suppose Ill install a custom kernel and enable screen wake features that way.

Okay. So after hours of tapping. Which might i add. My fingers hurt, I am now able to activate the screen. Pausing after each tap, using my finger print area to tap "not to be confused with finger tip". The screen will activate. Also note, the standard two taps works sometimes, but with four presses, i seem to get the best results. Give it a try people. I have a theory the hardware has not failed. But yet, the activation area pixel size value changed. Either due to a conflicting app install. A intermittent system glitch etc

I'm having the same issue with my G2. Knock-on/off was working fine. Had the phone in the sun for a little while (maybe 2 hours) and the knock-on has stopped working completely. Used a drawing app on my screen and found no dead pixels or strips. Knock off still works perfectly though.

This could also be an issue with your proximity sensor. If something (screen protector, finger, dust, etc.) is blocking your proximity sensor, it could be reporting to the phone that it is in a pocket, and to keep the screen off. Try to clean that area, and avoid obstructing the sensors "view". As for the leaving it in the sun, you could have damaged the sensor? You could test it by making a call real quick and see if the screen turns on when you pull the phone away from your face.

The sensor seems to be working fine. Just tested it.

Ya i got the same problem....at home it works perfect but when i went outside in the sun i can double tap like hell and screen didnt turn on(it turns on but cant see anything because its too dark like screen brightness is lower than low)...also power button didnt work...the proxi sensor is ok...i run the test menu and it shows that everything is ok...i also sent it back to my carrier and after a week of testing got it back. They found nothing and said that my described problem is a "feature".... sometimes it turns on after tapping und pushing the power button like hell and sometimes it doesent..
Your screen turns also on with very very low brightness or it is off? When u look really really close u can see it...for example hold power button and u can hardly see the white power off/reboot popup...but i dont know where the problem can be...germany d802 version..(Sorry for my BAD english)

My screen turns completely on and off when I use the button/knock-off feature. I'm going to take it to a technician today and see what they have to say about it.

First, What are you running on your device? Stock? Rooted...

I had given up on knock on but tis actually works. (not 100%) but it actually turns it on. WOW
Is there a way to adjust the "activation area pixel size value"?

This^. For me I have to use my entire thumb or even palm, but it occasionally works.(still like 1/30 tries). This leads me to believe that it is software related. This one issue is killing me. I hate using the power button on the back so I only used knock on. Now that it's not working I'm hating this phone. Knock off works great and I know knock on is kernel based so maybe someone can create a kernel that fixes this issue.

This did work for me. Fixed the knock on feature on my D802.
Credit: Smith I Run (Thread from android central. Can't post link to thread)
There is a solution; (not sure about it, my friend had the same problem and he fixed it with this method)
Open dialer menu and type;
5689#*980# (Sprint)
3845#*801# (T-Mobile)
3845#*803# (AT&T Canada)
3845#*802# (International)
3845#*800# (At&T)
3845#*980# (Verizon)
And when hidden menu is showed up, go to "Settings"
and go to "Update Touch Firmware".
The touchscreen won't work until after 5 seconds, Wait for it and if touchscreen gets working, exit the menu.
Lock the phone and try knocking on the screen, It should be working :laugh:

Notification of high temperature when enabling hotspot

Recently when i wanted to use the hotspot, I got a notification for high temperature. Funny thing is when I touched the back of the phone, it's not hot at all. Is it possible that my phone's temperature sensor is damaged? I'm not sure as I've tried checking the temperature sensor with an app from playstore and it's working perfectly fine. Can someone please help me with this?

Is it possible that it might have to do with me blowing the phone with hairdryer to apply skin? I once blew it til it becomes quite hot to the touch, and notification pop up to remove some apps from the background. but when i enable hotspot from settings, doesn't have the notification. idk whether it's software bug or something else.

Maybe it's your rom, if rooted...
