My screen randomly switches/flashes on and off....

It's quite obscure... while the screen is switched off, it arbitrarily switches on, but within a split second, it switches off (causing a flashing effect). Anyone else experience this? Any solutions?

My girlfriend's xperia play does the same thing. while the screen is turned off, her phone will turn on as if you were to press the power button, then turn back off after about 5 seconds, and will keep doing that for hours. ive been trying to figure out whats causing it but i have no clue. did you ever figure it out?

simple,
1. diagnose what's ur phone problm...
- flash it to original ROM / stock ROM or any recommended ROM
- if problem still --> h/w problem
2. if u had xperience in disassembling phone, try to disassemble it, and see if something broken. 1st priority, check flex cable since it is usually broken. if nothing wrong --> service centre is least option

Possible work around for WiFi connection cycling from Boot and sleep....

For those having the constant cycling of the wifi after coming out of sleep or reboot, try this workaround.
Boot or wakeup Nook.
Enable wifi (any method)
Go to Google maps
(don't worry if the map isn't showing yet)
sweep to an area of the map you haven't been before
zoom in several times.....
wait up to 10 seconds....
Hey look the wifi connected and is stable.....
turn off maps...
I have been using this workaround for three weeks now and it works every time and I don't know why this works, but it seems that having an app drawing data seems to break the wifi out of its cycle loop.
PS. I am using this rom...

and this statusbar hack...
http://forum.xda-developers.com/showthread.php?t=999214

Happened to me once. I just turned off wifi, then turned it back on.
I also set wifi not to turn off with the screen. I turn it off manually.

And something I noticed in the last few days is that the wireless is really prone to this problem if you use the advanced settings to toggle wireless off when the screen blanks. I currently have tasker set up to turn off wireless when the screen is off and that doesn't give me any problems. I've been doing this for weeks on the recent cm7 nightlies without a problem

You should've just put that in the title, that you have Nookie Foryo 0.6.8 running Brian's status bar hack.
But thanks for the suggestion. Will give it a go.

There is an app in the market called waketimer that does this also.

I have the wifi cycling issues coming out of sleep with my Froyo Nookie 0.6.8 too.
The work around I found was just to hold the power button until the shutdown menu appears. Do nothing and in about 15-30 seconds I see the wifi connect on the status bar, then I cancel the shutdown menu.

After autonooter3, I'm having the same issue for the first time ever on this device, on rare occasion the wifi won't startup. I downloaded/installed a free app called "Auto WiFi Toggle" and I haven't see the issue surface since.
Could any of you folks let me know if this little app may have solved the problem, or is it just sporatic luck.

Nook shutting off

Has anyone experienced their nook will shut off where the only way to restart is to power it back on?
I am running miui.us if it matters.

Yes, it is called Sleep of Death (SOD). It happens when you have wifi set to stay on when the screen turns off. After a while the system will go into deep sleep (as it's supposed to do) but if you have wifi set to also stay on, sometimes it will not wake up. There are workarounds to prevent this, but they are usually not very satisfactory if you want wifi on. Search the forums for discussions on SOD. It affects all newer versions of CM7 including miui.us.

I have this too, also running miui.us. My solution was to set the Nook to never sleep. I tap the power button when I'm done, the screen goes blank, I tap the Nook button or power button to use it again and it pops up in a second. Wifi quickly connects and I'm in business.

[Q] Wifi/3G not connected whilst phone is in 'sleep'

Okay. I noticed today that when pressed the power button to wake my phone from sleep the wifi or 3g (depending on where i was and what I was connected to, ie home or away) icon was not showing and thus indicating that it wasn't connected. Hmm, I thought it was odd, maybe it was a display error. But I then noticed that my emails and gmails all came through a few seconds after I unlocked the phone (and the connection icon appeared) and that they had all been sent whilst the phone was asleep. So, it seems to me that the phone is disconnecting from any data source when it goes into sleep mode. Now, I am right in thinking that the whole point of push notifications or setting your email to sync every 5 minutes is that the phone will remain connected even whilst asleep, and then wake up (briefly even) when it picks up an email?
I had no power saver on, no smart sync, wifi set to never sleep. Is this normal? It's pretty important that I get my emails as and when they sent to me. Any advice would be great. I am wondering if it's a bug, and whether I need to take to the phone back to exchange for another one?

you're sure power saver in the top menu wasn't on? because that's what it does, turns off wifi and data when the screen is off for an expended period.
maybe cycle it on and off a couple of times and see if the problem persists...

No, isn't normal.
So, can you upgrade to the latest firmware and, maybe, do a full wipe?
Did you install some app for battery?
And check that your power saver isn't on...

Check under power, setting that sleep mode is off. That on by default on mine. It turns data off after extended screen of time and doesn't require the power save to be activated.

Hmm, no additional battery apps, power saving toggled and definitely off (I purposefully turned it off because of it's data management policy), and sleep mode set to off.
So, I'm right in thinking that you/others actually get notifications then? and wifi/3g is working fine? Looks like it's a return and hope that the next one works (I only got the phone 7days ago). My software update says no updates available, though this is likely to be EE fault. If I can get the shop to exchange I might just do that. Ho hum, another 3 hours setting the thing up again then...

It seems to be a Wifi switching itself off problem...

So, a quick update in case anyone else is having this problem.
I reset the phone to see if it would make a difference and it kind of has. Now I have noticed that if I am using mobile data it's fine. Things are pushed, notifications come through. But if I use Wifi it's a different matter.
it seems that with Wifi on and connected then it works for around 15 minutes when the phone is sleeping (I have done a few tests). After this it seems to shut wifi down and hence no notifications. So it would seem to me that although Power Saving is set to OFF, and Sleep mode (ie no data in sleep) is set to OFF, the phone is still disconnecting from WIfi regardless of the settings. Which is a bit frustrating as I don't want to be connected to the mobile network all the time, especially at home, but still want to know if I receive emails.
Anyone else experienced this Wifi switching itself off issue (and then switching itself on as soon as you manually wake the phone?)? I have to decide whether to return the phone for a replacement or not. If this is a wide ranging issue it might not be worth it - though I'd have thought a simply thing, like keeping wifi on at all times wouldn't be hard to make sure it worked.

there are a few apps available on the play store such as "keep wifi alive" which might do the trick.

Okay, now I feel a bit of Doughnut! I think I've found out what was causing this. So, even though I had Power Saver OFF, Smartsync OFF, Sleep Mode (disconnect data whilst sleep) OFF, I hadn't had a proper look in the Wifi settings, and under Advanced I found:
Advanced>Keep Wifi on during Sleep. This hadn't been set to Always and was set to 'Only when plugged in'. So, changed to 'Always' and now it seems to work (and that would explain why I got emails through the night when charging).
So, apart from feeling a little red-faced for not exploring every single menu available, I am happy it (seems) sorted. If anyone has wifi dropping whilst phone is sleeping it seems there are four steps:
SmartSync = OFF [in Mail app]
Power Saver = OFF [in status bar and Power Settings]
Sleep Mode = OFF [in Power Settings]
Keep Wifi on during Sleep = Always [in Wifi>Advanced Settings]
Hopefully this'll help anyone else who has been having a bit of prolonged blond moment with the phone settings. {retreats to corner}

I have similar problem. Even when I have everything OFF as you suggest, I get disconnected a second after screen goes off. When I turn phone back on, I can see that wifi is on, but all aps are off and wont connect again. I have to turn wifi off and on and applications like skype go again online. I have this problem at home and also at work on corporate network. I have even tried apps that should keep wifi on, but with no change.
Interesting is that after the phone goes to sleep mode, I can see that speed of wifi is changing on phone. The phone actualy stays connected to wifi, but doesn't send or receive data.
The router at home is TP-Link 1043ND with DD-WRT (flashed to last firmware to see if it fixes this problem). I'm not sure what brand and type are corporate APs, but could be some cisco or similar.
Any advice what else I could try?

[Q] Z1 screen takes a couple of seconds to turn on

Hey guys, I just updated my C6903 to 14.1.G.2.257 last night, I have an Australian stock model.
I noticed this problem yesterday, but if I press the power button to turn on screen it takes about 2-3 seconds for it to turn on. This is consistent behaviour, happens all the time except for when the screen is turned on around 5 seconds from the last turn off.
I have turned stamina mode on and off, auto brightness on and off, and it didn't seem to do anything. I have also done a factory reset too and the problem is still there.
Anyone else experiencing this?

I haven't seen this problem but you might want to try a factory reset.

I did that and the problem persisted.
However it seems like I might have solved it... the problem is now reduced a lot - it turns on immediately most of the time. I have a feeling this might be tied to the temperature of the phone, as yesterday and today I was setting up/playing with camera, etc.
Will continue testing and see what happens.

Similar issue. I had this on my galaxy note 2 as well. It turned out there that it was just a thing with exynos 4 quad where it took a little bit to get out of deep sleep. I assumed it's a similar thing with the snapdragon 800, but maybe it's actually a bug. It would be nice if it were.

Mine takes max 1 full second to turn on at the longest if not its normally instant

disable "auto kill when screenoff" in your task killer app.
