Lcd dim issues

I'm having issues where after going to sleep, it wakes up with the lcd very dark. It doesn't matter which level of brightness I put it on, the lcd is still hard to see. Rebooting solve the problem. Just wondering if anyone experienced this too. I hope it isn't my lcd dying...
This happen on both froyostone and bangster. I'm on the latest radio using tmousa.

I had this on bangsters 1.2, but haven't seen it on 1.3b, but only been running that build for a few days.

i had this a few times before on a shubi build. I came to the conslusion that it is the screen not fully coming out of sleep. Seeing as it only happened when I put the phone to sleep and then tried to wake it immeadiately or got frustrated and impatient with it and tried tapping buttons repeatedly until the screen came on.

I had this same experience. Patience is a virtue with these phones. As long as I wait if its taking a bit to come out of sleep, I get zero problems.

thanks for the advice. I hope its just a software glitch. I will just have to be more patient when coming out of sleep.

My solution

Here is my solution, i posted it in a similar thread, I think the key element here is the bsb tweaks part, hope it helps, thanks:
I solved this problem in my phone.
even turn on/off/on/off/on/off etc the screen, the devices wakes up correctly every time.
I don't really what exactly fixed but.
i installed Miris romm 20.0, then i turned off the auto screen off *start/system/power, so the screen nevers dims or turn off. I turned off the charge the device when it is connected to the computer, turned off quiet pickup, turned off 3g.
and now i think this is the key, installed bsb tweaks and turned off everything(even power savings), disable data connections and screen rotation, I only left use high glymp cache. reboot and run android, in winmo i dont have anything installed besides bsb1.6
in android i have the task killer on and set cpu at 768mhz ondemand. no profiles. battery last well over 24 hrs moderate use. by the way im using shubcraft, and the gsensor disabled kernel. thanks,
edit: also my auto sync is off in android and my wifi is always on.

I dealt with the problem by putting a widget to control screen brightness on my home page, if it goes dim I can find it ' blind'

Yeah it does happen to me if I'm being impatient and banging on the screen before it fully wakes up. Haven't found a real solution yet, but so far I would just try my luck by turning on/off/on/off several times, hoping that it get stucks momentarily again to let if "fully" wake up. Worst case scenario, reboot.

lock screen stays on, won't timeout

I used to get great battery life on my Iconia but lately something is turning the screen on (to the lock screen) and staying on and just draining the battery. The screen does timeout when it's unlocked like it should, i have it set to 1 min i think. I'm rooted and running taboonay. i can run logcat but i don't know what to look for.

updated to taboonay 2.1b and it seems to have fixed it. i think it was an issue with it looking for a SIM card.

switched to lightspeed rom. it's doing it less often but it still happens. ideas?

This is no doubt a rom or kernal issue..
It could be a rogue app as well. I do not have any sleep or wake issues. No issues at all im running the near stock rom for us. 3.2

happen to my stock 3.2 A500 too, found some info pointing to wireless, connected wireless router, computers in network etc. Only things i can do to stop it wake up from sleep and stay on, is to disable wireless/airplane mode before sleep.

[Q] need help or advice on deep sleep problem

Hey guys,
i am on latest CM9 quarx build..but my phone is not going into deep sleep atall
it says 0% deep sleep in CPUspy...tat has become a headache..i was on epi CM(..there also it had come problem..then installed latest quarx build..then it was going into deep sleep unto few hrs ago..now it says 0% deep sleep.
I cant few detailed battery drinking info on ICS unlike GB..
Any help would be appreciated name of the app..or advice..or any kind of help will do..
Thank you

Try editing your build.prop and adding
Code:
ro.ril.disable.power.collapse=1
Don't know if this will help , but in the event that it doesn't , try ending processes before locking the phone , or use some system analyzer to see what app is stopping deep sleep
Herpderp Adreno + Tegra.

thanks but i did a full data wipe and reinstalled everything from scratch..later restored apps with the help of titanium backup
its pain in the ass to do everything from scratch...anyways if still i face this problem then will report back..anyways could anyone suggest me some apps which can findout which app or process is the culprit?

Try this one:
http://forum.xda-developers.com/showthread.php?t=1179809

I had the same problem on CM7 120126.2206, and it turned out that Google Maps was the culprit. However, I discovered that Google Maps doesn't prevent the phone from going into deep sleep when the GPS is disabled. Try disabling GPS whenever you're not using it, and see if that helps.
Edit: after further testing, it seems that Google Maps may not have been the culprit after all, or I may have more than one problem with deep sleep. Occasionally the phone gets locked out of deep sleep even when GPS is turned off; yesterday it failed to enter deep sleep even while the phone was untouched for 4 hours. The "BetterBatteryStats" app indicated listed "wifi_wake" under Kernel Wakelocks as the primary culprit. Disabling then re-enabling wifi solved the problem, at least temporarily.

Wake Up and Sleep Bug - ICS AOSP 4.0.4 (khanning88 builds)

Hi All -
Can someone help me solve a problem that I am having with my K1. When my K1 sleeps for more than 30 minutes, it wont restore itself by hitting the on button. I have to hold the on button until the panel lights up and then reboots.
I experienced this when I had Honeycomb installed and the auto brightness was turned on, I have turned off the auto brightness and set the brightness to 40% (estimated) and I still have to reboot to wake the K1 up.
I'm running Lenovo Ideapad K1 w/Rooted Official AOSP 4.0.4 rev. 2 (khanning88 build)
Any suggestions?

I came here researching the same issue. Pretty annoying. You cant sleep it, if it goes too long powers down. Probably best on battery savings, but annoying when you just pick it up and have to reboot everytime in between use.

I don't have any problems with the sleep bug. I'm also running the AOSP ICS rom. You can try reinstalling your rom through CWM.

No problems here either. Get CPU Spy and check the times spent at each frequency (also see if you are going into deep sleep). Before you reflash the ROM, you might try to wipe both the cache and the dalvik cache and reboot - that may solve the issue

No problems here either. Did you flash the rom via CWM or NVFLASH? I installed it using NVFLASH and have almost no problems, id recommend flashing it that way if you haven't.

the problem is not because of the auto brightness. You have to make wifi connection stay enabled during sleep. Go to Setting - wireless - advanced and make it always stay enabled..

[Q]Experiencing sleep of death with Lenovo K1 with CM10 and Wifi IS SET TO ALWAYS ON!

Hi all,
I am experiencing the dreaded sleep of death on my Lenovo K1, I cant post in the android development section as I dont have 10 posts yet. I flashed the V2 CM10 via NVflasher and then updated to V6 via Clockword Recovery. I have checked that my Wifi is set to "Always on", I have not done a system restore so this is a clean device. This is now my 3rd flash of this image with the same problem(My previous JB AOSP worked fine). Does anyone have any idea what I can try next?
Thanks!!!

I'm having the same problem with my WiFi version of the K1. I have flashed krook1's build a couple of times and have tried setting the WiFi to Always on. I also have tried Better WiFi On Off and Soft Locker apps to manage the wifi and keep it out of deep sleep (both recommendations in the dev forum) but neither have helped. Every time my screen goes off, the device appears to continue functioning; I can hear notifications going off for emails or text messages. If I try to turn on the screen again using the power button, the two lights on either side of the home button will flash but the screen does not turn on. I then have to hold the power button down and boot up the device again. It doesn't matter if the screen times out or if I turn it off manually, it will always die immediately after.

Hi,
I was experiencing the same issue, the Sleep of death, and would not wake up after turning the screen off or locking the device.
After a lot of testing without positive results, I found this app from the market:
https://play.google.com/store/apps/details?id=com.omd.autoscreenon
It allows to have a "Wake Lock" sensor on all the time, it drains battery a little faster (I haven't noticed much of a difference) which seems to have solve the wake up problem.
I've tried this app the whole day and I haven't had any SoD so far.
Hope this helps.
