Screen dims, but never shuts off

I just noticed this morning that when I hit the power button the screen only dims now. I swear it used to shut off the display completely before today, and I know for certain that is how it worked on 1.6. This really is annoying, because now when I put it in my pocket the 3 buttons are constantly being depresses and they vibrate, which lights the display again. That coupled with this stupid lock screen that I have to try to open 3-4 times is really making me angry. Maybe it's just me thugh.....

I'm assuming you upgraded to 2.1?
I remember reading somewhere that someone had a similar issue after upgrading to 2.1 but then they re flashed 2.1 a different way and problem went away.

Same issue here, it really eats up my battery life, and I do end up pushing those soft keys all-too often... I am on 2.1 and that is definitely when the problem started, I'm going to try reflashing to see if I can eliminate the issue.

try the steps found here on streaksmart.com. She reports that she has no issues when its done that way. I don't have my streak yet but will follow these steps when i get it.

I had a similar problem before, only the screen would go off and on again and stay on!
Turns out it was an APP that done this.
It is possible an app is causing the problem.

Don't leave wifi on when not using and the problem disappears.

I've been experimenting with what's been causing this on mine, and I noticed that sometimes wifi will not shut all the way off. It hangs at "Turning off..."
So I tried not letting it sleep with wifi on, I turn it on if I need it, then turn it off (really a big pain in the butt) but went two days with no "no sleep" problems.
Today I tried leaving wifi on all the time, not two hours later it happened.
Since it's not happening to everybody, I wonder if it has something to do with our wifi setups. Maybe the router brand, or the encryption type, or something?

Last night I powered off the phone before better. I have wifi on all the time and I never shut it off. Today though, I have had no issues with the sleep function. It's still mid afternoon so we'll see if it continues this way. If so I will explore the wifi solution as well.

I was having this problem and somehow this setting was wrong:
SETTINGS>>APPLICATIONS>>DEVELOPMENT>>STAY AWAKE
mine was checked and we all know what that mean. Check yours to be sure if your not up for flashing again. Just a thought in case you overlooked this...

Yes, it means the screen will not time out and go off when it's being charged, but you can still turn it off, and mine wasn't plugged in when I couldn't turn it off.
I don't think this is related to what I've been seeing, but thanks.

It seems that Bluetooth did it today. I was fine all day going black on sleep with power button, but once I switched on wireless to connect to my car stereo it never went off again. Even if I turn off the wireless I have to shut down and reboot.

Same here. Started car and it showed zero signal strength for the phone on the dashboard display. Pressed the power button on the Dell Streak and the car display then displayed the signal strength. From then on, the screen would dim but not shut off.

Was your wifi also enabled (even if not connected to any AP's) when this happened?

Yes, and I couldn't turn it off once the "screen dim bug" took hold. Today I've rebooted and left Bluetooth OFF and Wireless ON and have not had an issue all day long, and that's making calls, using 3G, wireless and running a pile of apps. I think I can live with no Bluetooth until the next release.
Pete

I don't think it's BT. I think it's wifi not recovering properly from sleep mode.

Fair call. However, I've now had BT off for 6 hours and I'm using 3G, wireless and USB transfers and it hasn't hiccuped yet. This is the longest I've had with no screen dim bug.
I did notice that when I walked out to the car, the Streak could still "see" my home wireless network, then starting the car and the BT pairing and connecting is when the screen dim bug came back.
Maybe it's when both are run at the same time and both are connected/paired?

I agree its looks like its a wifi issue. I always keep my bluetooth off and it still did it.
I got mine fixed... but the problem is i did a bunch of steps and now cant figure out which one actually fixed it. its been running great for 12hrs now.

What I did, since I noticed that wifi sometimes didn't sleep or wake itself up properly all the time (which i think is what's affecting our Streak sleeping), was turn off the wifi sleep. In other words when my device shuts off wifi stays active.
However, I then used "Tasker" from the Market and setup two profiles. When the screen goes off it shuts off 3G, wifi and autosync. Then when the screen comes on it turns on 3g/wifi, waits 20 secs and enables autosync (which then initiates a mail/calendar/contacts sync).
This has worked perfectly, and I get mad good battery life to boot. Now this means I don't get mail/updates (facebook, weather, etc - still get calls and txts obviously) but for me it's not a big deal especially for the battery life.
I may eventually setup more Tasker events to duplicate "Juice Defender" and poll every half hour (3G only, when screen is off only) to get my updates, but for now it's been working great.
I also setup profiles so if I'm not where I have wifi pairings it shuts down wifi. Also if it detects I'm connected via wifi (at home for instance) it disables my lock screen. I also have it set to only start GPS for apps that need it (Maps, Navigation, Places, etc) and that helps save battery too.
Tasker is an awesome app for $3.99. It has a steep learning curve, but there are enough walk-throughs available to teach you how to do the basics.

Found the fix on Modaco. Have a look at the last page of the thread called "2.1 Bugs ....., Add what you find please....."
I never knew there was an "Advanced" menu for WiFi!

yeah that is not it. I also have mine set to never time out so does that mean it will never shut off either? Anyway, it keeps happening through the day. Wifi and bluetooth do seem to have something to do with it, but I need them both on all the time so the only thing I can do is reboot. Then it is good for a couple hours. Are the any apps that have a reboot? That's one thing I miss on the iPhone.

[Q] Annoying wifi deactivation

Hi,
when I am downloading a large file, my screen turns off after some time when I do nothing. So far so good. But when I resume to my Android I must see that the Wifi-connection was turned off, too - I think because of battery power saving.
But it was turned off during my file download, so I have to download it again and I have to keep my screen not to turn off by tapping on it periodically. That's what is annyoing me.
I recognized that the connection is not deactivated directly after the screen was turned off. It lasts some time (minutes?) then the wifi connection is turned off, too.
Is there a way to prevent the deacitivation of the wifi connection when the screen is turned off?
Thanks for your answers.

Yes,
Goto settings>wireless connections>wifi adjustments
There you should find an option for WiFi selection politics. Just choose not to never disconnect.
Cheers

Hmm, it is already set to "Never disconnect".
I think this setting is only useful when you want to switch automatically between mobile data (GPRS/UTMS) and WiFi.

No. That happens whether you want it or not if you have a wifi access.
Or I have a couple of busted phones at home that totally ignore this setting.

Tell your screen to never shut off, then change back.

Wifi issues?

After I got the touchwiz update and the second smaller one my wifi is messed up. It doesn't stay connected once the tablet is left alone for a couple hours. The signal strength color turns to white instead of blue when it does this. To remedy I have to turn the wifi on and off on the tab. Anyone else with this issue?

I am not seeing this issue. Have you tried a factory reset yet?

check to see if you have wifi set to never sleep (in advances settings). i had similar issues and setting it to never turn off worked for me. no battery drain issues with that setting either.

Thats bugging me too. Not always but from time to time I see "No internet connection" when the tablet is left alone. Before the updates I never had this. The other issue is wifi roaming. To get connected again I have to push power button, sometimes unlock screen, even sometimes it waits until the wifi settings screen. Dumb!

Ya I have it set to never turn off. I would hate to have to factory reset it and lose all my settings and Apps got a ton of stuff on this bad boy.

Apps are easily re-downloadable. If you're rooted then install Titanium Backup and back up all your apps with settings.

Do you have aan older router? I have the same problem (I have to turn wifi on/off if I leave the tab alone for 20+ min) but only at my office where my router is a bit older. At home with my brand new Linksys I have no issues.
My wifi is set to never sleep btw...

Screen on with no reason and battery drains...

i have read an old thread with a similar, not solved, problem, but i didn't wanted to write in a so old thread...
so...
when the wifi radio is on, my iconia a500 suddendly turns on the screen and it stays on also for various minutes, sometimes i guess also until the battery is completely finished (i have found more than once the tablet off because of battery drained in the morning, so i guess it was with screen on all night long)
this happens also if i set wifi to go off when display is off.
i have tried many different roms (taboonay, lightspeed ... and now i have thor rom 14.2, installed yesterday) but the problem is always here.
if i manually turn off wifi, this seems to never happen... or at least it never happened while i was watching the tablet during the last months
does anybody knows a solution, a hint... or anything that could be helpful to make this issue less annoying?
thanks!

You might have a program installed that is constantly calling for wifi access?
That's the only thing I can think of?
On my Rom, I haven't ever experienced that problem.
My settings are as follows:
Airplane mode on
Wifi On
Wifi disconnect policy: when screen turns off.

also when i just turn it on it happens, even with no services or program needing wifi...
but you gave a me a good idea to try...
i will put airplane mode on and check what happens now
and anyway, i'll check again my programs

Post your findings

i'll keep my eyes on the screen

hm for me it sometimes happen but it's like once it two or three days so it's hard to track it down ;/

For me it is quite common....
To check it i keep it next to the tv while i watch it, or next to the computer
Dal mio Iconia A500

Can someone please clarify what I am missing in these settings:

If airplane mode is turned on doesn't that over ride the wifi on setting?
So if airplane mode is on wifi will always be off so the disconnect setting has no bearing.
Can someone please confirm above or explain..
thanks

no, you can put airplane mode and then turn on wifi
and seems like it is working well... but i don't want to talk too early...

Airplane mode is for tablet/phones with data connections. Airplane mode just turns that off

Yes, but for some strange reason it helps with the wake up problem some have

That's what I was getting at - when airplane mode is turned on it overrides all other settings and wifi can not be engaged in any way until it (airplane mode)is turned off.

Yup I was just answering Spud
Airplane mode only refers to the 3g/4g cell radio (so it turns off wireless network data/phone calls/texts etc.). You can still turn on wifi and use it when airplane mode is on because this is a different radio (well in the a500 there is no 3g radio). After all many airplanes now have wifi on board, however you're still supposed to have it airplane mode.

Thanks.
I haven't been able to turn in wifi with airplane mode on - it takes a longer push (hold) on the wifi button to engage.
I now have wifi on with airplane mode on - didn't realize airplane didn't also disable wifi.

Incorrect! You turn Airplane Mode on, which turns off wifi, then turn on wifi with Airplane Mode still turned on (and airplane mode stays on with wifi turned on as well).

after some days trying i have noticed that putting in airplane mode solves the problem...
but not always the tablet turns off wifi and stay in airplane mode when i turn off the display, it is surely some annoying app (or widget) that makes this happen.
i'm trying to understand which one

The only way to do that is process of elimination. Knocking out the variables one by one until you find the culprit, which has the potential to be a long, painstaking process. Start by uninstalling, one by one your apps that require internet access, and wait a couple days In between each one to see how your tab reacts.Then again, it may be an app that you wouldn't think needs wifi access to work, but in the background is calling for access.
Good luck with it!

[Q] App or mod for wifi sleep when screen is off

Can you recommend an app or a mod which control wifi connection when the screen is off? I notice that if I enable wifi, I got 20% battery drop per a day, but I got 2% drop if I disabled wifi. Still, I like to have wifi on when I am using it, and clicking several time to enable wifi is quite irritating (relatively). So I thought there might be a good resolution to handle this my lazy problem.
I searched it on android market, and can find several. Can you recommend any one which will work well with NookTouch? I appreciate your inputs.

Same problem pal. But I also can't fix wifi not reconnecting when nook is up from sleep state issue. Suggestions?

I use the power widget that comes with ADW. I can turn WiFi on and off from my home screen with one tap.

Is it possible for it to be done automatically? Like on my smartphone? When wifi is turned on and my nook goes to sleep mode then when it wakes up wifi is off, in "disconnected" state.

I use the program Llama. It lets you set up all sorts of conditional changes for phones (similar to Tasker).
On my nook, I have one event trigger. When wifi turns on, Llama delays for 5 minutes, then turns wifi off.
It isn't exactly the same as turning off wifi when the screen turns off, but it helps me save battery. I currently have it send a notification to let me know it is turning off wifi, so I have the option to keep wifi on if I so choose.
Edit: Llama does have an event trigger for Screen Off, but I couldn't get it to work. Maybe the Nook doesn't turn off the screen in the way standard android phones do, so the trigger doesn't run.
Edit 2: I just realized you wanted one that turns wifi off when turning the screen of, then reconnects when turning the screen on. If Llama correctly detects the screen off/on triggers, you could set up two events, one to turn wifi off and one to turn it back on. I haven't gotten it to work, so maybe Llama isn't going to work for your particular needs.

The NST is so heavily customized by B&N that you cannot rely on the "usual" events being triggered.
They only did what was necessary to save enough power and get the device to work and I don't blame them for that.
I'm pretty sure there's an event triggered that can be used for this particular task tho, if I get some spare time I might dig into it.

Well, I'm the impression, that my nook does that. I mean, when in sleeping mode - the WIFI is OFF. But when I awake the NOOK, wifi turns ON by it self and connect to internet. What I suspect, you might have the problem that other users experienced (including me) ... that you will have to change one file. Read more about it here.
I hope, this will help you.

Thx for all help !
