I never used the led notification, but the audio notification still works. I just tried it out with my Touchdown mail client which pushes mail from my Exchange server at work.

So with wifi set to never sleep, I get a notification tone as soon as I get an email regardless of whether the screen is off. However, if wifi is set to go to sleep whenever the screen is off then if I get an email while the screen is off I will not get the notification tone until I turn the screen back on.

This behaviour defeats the purpose of having push email, since I have to check my phone to see if I have email rather than my phone telling me when I have email.

One more thing that I just noticed is that when the phone is stuck in the blank screen mode, I am still able to receive and answer calls using both the talk button as well as doing the accept slider motion on the blank screen where the accept slider is usually (although it doesn't vibrate as usual).

Also, text messages arrive fine with the normal audio notification but of course I just can't see them until I pull the battery and restart.

I hope someone is able to come up with a fix for this soon as this problem is really annoying.

Haven't had time to work on a fix yet sadly... Not even sure where to begin.

Default Possible workaround

Hellooooo,

Possible workaround for the black screen issue:

xda-developers - View Single Post - Can't turn Desire on from standby

Keep in mind this fix is geared towards Telus users. If you're a fido/Rogers user, please select GSM only instead.

Keep me posted on if this helps out!

Another fix according to reports would be to rollback the kernel. I'll see if I can post a zip to rollback the kernel to the old version... Only catch to this is you need the phone to be rooted + have recovery installed.

karender, would 3g and 2g switching have anything to do with our shine plus blackscreen problem? rfyhn and I do not use the mobile network, only wifi. I experience the blackscreen while using the phone sitting in one place, not moving from one cell location to another.

I'm giving possible fixes, not detailing rocket science. And 2G + 3G is not only for data. It can be for voice also... What's the harm in trying? If it helps, good... If it doesn't, too bad we'll find another solution (Like the kernel)...

Well my phone just blanked out 3 times in the past hour. This has been the worst so far.

I was not criticizing, just adding 2 cents to discussion with hopes of eliminating the source of the problem. I appreciate your efforts to look for a solution.

I get the exact same problem. Might be related to the wi-fi monitoring performed by Juice Defender.

I'm pretty convinced this has something to do with Juice Defender. I installed Ultimate and it crashed a lot more, many times in a row.

Come to think of it, karendar may have a point. I don't recall it ever crashing over data.

My girlfriend's phone had the issue this morning. Here's what happened:

She's always on wifi because she doesn't have a data plan... She always has an alarm that runs on the phone. The alarm runs at least 10 times per day (LED notification). It "froze" this morning when it went to sleep while the alarm was ringing. So here's the possible scenarios:

LED nodifications cause the "freeze"
Sound playback causes the "freeze" (Or access to the audio module)
Wifi causes the "freeze".

I quote freeze, because it's only a partial freeze... The buttons are less responsive than usual (As in they do respond, but delayed by 10-15 seconds) and the screen backlight is completely out. (If I put a flashlight next to the screen as I've mentionned, there is something on the display, but very faint)

So... I'm thinking the kernel code or .so drivers are the possible culprits. Considering I'm not a kernel dev, I can only find workarounds. I'll post the 2.1 kernel for flashing and testing to a courageous soul willing to attempt running it later today. I'll also post the 2.3 kernel just in case.

The tester will have to have Amon-RA recovery installed to be able to flash these kernels. So root + Recovery from all things root needs to be installed.

Thanks!

so juice defender fully removed, and hardly used wifi yesterday and it crashed only once. Today I will try not to use wifi at all.

For all those without a Telus data plan, the lite is 100 megs for $10 a month. I have never gone over the 100 megs. 100 megs is plenty for email, IM and the occasional pic upload.

Default Wifi set to 'always on' in the sleep policy settings

Hi Guys, I'm new to the forum so you have to bear with me if this has already been covered.

My wife's LG Shine is having the same blank screen issues after the 2.3 upgrade that seems to be affecting a lot of users. She has put her SIM back into her old BlackBerry so I have been messing around trying to fix the problem myself (with limited tech experience).

I noticed that if I set the WIFI to always on in the sleep policy, the screen problem does not occur as long as the wifi is continuously connected to my home network. If I take the phone outside and it loses signal, the screen issue starts again and I have to remove the battery. When I left the phone on in the house, it went 48+ hours without a problem but I had to pull the battery 3 times as soon as I went out.

Hope this helps.

this is absolutely true!! I have noticed the exact same thing and it is my belief that the problem lies solely with the wifi ( the wifi locks up and displays an error message and the next time the screen turns off I am unable to wake up my phone ).. when wifi is off I never have a problem with the screen waking up

Question because alot of you are in this thread: Who here has 2 phones due to the 2.3.3 issues? If someone has a 2.3.3 phone they have as a spare, who's willing to do a little experiment? We successfully fixed a bricked phone with a procedure with the joint efforts of Jiilik, myself and seanre453.

What we need for this person to do is use a flashing procedure to flash back the 2.1 ROM through a tool we found. Procedure will be added to this forum shortly. It'd be of great help if someone could test it.

Reason we ask for someone with 2 phones to do it is because this might brick the phone! We can't be sure the phone can be reverted fully with baseband, ROM, etc. from 2.3.3 to 2.1.

Thanks in advance to the courageous soul who tries!

Talking Suspect WiFi issue

My phone: LG Shine; rooted. My provider is Telus in Edmonton.

Android v2.3.2 very stable with almost zero problems. Upgraded to v2.3.3 via LG Mobile Support Tool and almost immediately I start to experience the freezing problems described in this thread.

After a bit of messing around I disable Juice Defender and the freeze problem almost, but not quite, disappears.

I am using the paid version of Juice Defender and it was working well with the 2.3.2 ROM.

On another board I discovered that dialing *#*#4636#*#* on the phone keypad brings up a test menu. (4636 = INFO). Some neat stuff in here. I didn't mess with any settings but noticed that the WiFi related items cause the phone to freeze. Eventually I get a screen asking if I want to force quit the application.

Bottom line is I fully suspect the problem is related to WiFi.

I will see if I can go 24 hours with no freezing. If not, I will disable WiFi completely and see what happens.

I did basically the same there. My phone froze once, all day. Wi-fi was enabled just that one time...

Uhm... 2.3.2? Was that even released for the phone? If you mean the v10d ROM, it's 2.1 actually...

And yeah, it's related to wifi. Not sure kernel is related, must be the wifi libraries.

Good catch. I meant to say 2.3.3 for me.

It only happens sporadically for me on the custom ROM... I posted a flashable zip for testing but noone's testing...

I'm finishing up the last items on my custom ROM and I'm moving back to the Galaxy S2 forums.

Had this problem too, but there's a way to fix it: If the screen goes blank but the buttons light up, hold down the power/hang up button for about a minute until you see the screen flash, then let go of the button, wait three seconds, and then press-and-release any button (except the camera button). You should get the swipe-to-unlock screen (or the security screen if you have a security-unlock code enabled). This will not reboot the phone.

If you had a Bluetooth headset paired & connected before the screen went blank and froze, you may have to manually disconnect and then re-connect to get the headset to work again. Depends on the headset.

Thanks TheSarge for the workaround, I never got the black screen enough to test anything.

Right now, I somehow tweaked wifi to turn off when it goes sleep. It's a pain when you resume it takes a while to connect, but seems to have stopped the black screen.

It must have been something I did in Juice Defender.

Turning Wi-fi off when your phone goes to sleep can be done by going to wi-fi settings then choosing Advanced from the menu button and adjusting the Wifi sleep policy.

Here are some updates on my experience with this black screen issue:

Setting the wifi sleep policy to turn off when the phone sleeps consistently prevents the black screen issue for me.

However, since I often need wifi on all the time it is not a good workaround for me. So far I have noticed that on occasion I can keep wifi always on for a day or so with no black screen but then somehow the problem reappears and then I go back to almost consistently having the black screen problem whenever the phone goes to sleep. I have not yet been able to determine what conditions cause the problem to go away or what causes it to come back but I am still investigating.

When the problem does occur I have not been able to get TheSarge's non-reboot fix to work (the phone never flashes after holding the power button for over 2 min), however what I have found works for me is
1) Hold down the power button for 2 seconds
2) Open the slider
3) Press the direction pad down at least 4 times
4) Press OK
5) Press OK again
After a couple of seconds the phone should reboot.

This helps me avoid having to do a battery-pull which is a pain for me since I have case for my phone that gets looser the more you take it off and put it on.

Also, as Karendar mentioned a few posts back, i've confirmed that if you shine a flash light on the black screen you can actually see the lock screen.

I basically did the above. No black screens in a couple days in a row now. Wifi turns completely off when asleep and it takes a few seconds to reconnect as it powers on. I have no problem with that at all... better than black screens.

You should get the swipe-to-unlock screen (or the security screen if you have a security-unlock code enabled). This will not reboot the phone.

If you had a Bluetooth headset paired & connected before the screen went blank and froze, you may have to manually disconnect and then re-connect to get the headset to work again. Depends on the headset.
Once again, the instant I brag about not having a black screen in a while, it happens immediately.

I tried this workaround and had no luck. I'll try again when it happens next.

I'm convinced that this problem is related to wifi. With wifi on, my wifes phone has the black screen problem many times a day but with wifi turned off it does not happen.

Yes it is in fact related to Wifi... LG actually have a support case opened for it, but it'll idle for a few years before it's fixed I'm sure.

Complain to Telus, maybe it'll make things move... I can't do it myself because I don't even have a service with them, just bought the phone used and unlocked it.

Yeah, they told me they would have to send it away and reflash it with 2.1. I going to upgrade my phone soon so I think we'll just wait till then and give the wife my old phone.

i updated my phone last week and i was happy for the first 5 minutes but then i got extremely pissed when my phone lost WiFi , then i locked it. i went to unlock, and nothing would happen. i was fooling around with some settings and i found out that if you turn WiFi off the black screen problem goes away completely, but because i don't have a data plan, and there's no internet, it defeats the purpose of having a smart phone. at least i can still make calls and text...

This update was a joke, I can't believe telus is still advertising it on their website.

On my phone, it always happen when I am using the Market app. The app with the new look on Android 2.3 is slow to start, most of the times it won't download apps unless you turn off the screen and turn it back on and worst of all, suddenly the wi-fi goes out and IF you turn off the screen, then the phone hangs and you must reboot. When I see that the wi-fi has just disconnected, I turn off the phone with the power button and restart it. Saves having to pull the battery but is still very annoying.

Keep in mind this fix is geared towards Telus users. If you're a fido/Rogers user, please select GSM only instead.

Keep me posted on if this helps out!
I may give this a shot. I see no one gave this a try yet. I've had it.

This did nothing - black screen 3 times in the past few hours after changing to preferred. I'm changing it back.
