I have a perplexing problem with two phones that I have. The issues is, when the phones go to sleep (either by timing out while on battery or when I hit the power button on the phone to turn off the screen), the CDMA radio will shut off after a while and won't turn back on until I perform one of the following:
1. Reboot
2. Make a phone call
3. Send a text message
4. Switch in and out of airplane mode.
I know when it's off because I will suddenly get a flood of text messages when I perform any of the above tasks.
I thought originally this was something wrong with my phone (maybe too much flashing), so I got another Galaxy Nexus (Sprint). Unfortunately, it does the same thing. If I keep it on a charger and do not turn the screen off, everything works fine.
The phones are a Galaxy Nexus that works with Sprint. Since I don't know when it happens, I captured a logcat of the phone overnight after I turned the screen off. The next morning, I had to dial out to "wake" the phone.
I have factory reset the phone, flashed another rom (it seems to happen to anything that was based on CM), All these have happened multiple times trying to fix the issue. I have wiped dalvik and cache with no avail. Is there something I'm not trying?
I tried looking around to see if anyone else had this problem, but came up empty.
Perhaps someone had had this problem as well and can direct me to a fix.

I've been using my S2 as a music player for a while. and its been running Liquidsmooth 2.10. and its worked just fine for ages.
my s4 was damaged, so i was using my s2 as a backup. it worked fine for a week or more, then suddenly one day, it just just killed it self. nothing was changed as far as rom/kernel or anything. i was just typing a text and all of a sudden the screen flickered, and the camera flash went off a couple times, the screen turned back on and the off again. then it just turned off.
i have not been able to get it back on since. it will show the SII logo for a few seconds then turns off. then proceeds to vibrate once every 2 seconds endlessly. thats all i can get out of it. it wont go into download mode or recovery or anything because as soon as i put the battery in, it tries to boot itself.
anybody have any ideas what is goin on here?

Sounds like the power button may be stuck which is a known issue with this phone. Here is a thread on the issue:

I've come to find out if the phone crashes this will happen, it's normal behavior believe it or not. If you will be patient and wait for about 7 to 10 minutes, the phone will finally reboot. The next reboot will be normal time again. This might be the device's way of protection, IDK.

thanks, this did the trick. but i think it may have been more so the volume up button. there is a metal piece that surrounds the volume button on the board, somehow it was coming off, pushed it back on and mashed the buttons a bunch, came right on.

This is almost certainly caused by a bad/stuck power (on/off) switch. It's a very common problem on all the US-carrier Galaxy S2 models. (Sprint, Boost, Virgin, Telus, T-Mobile, AT&T, etc. I don't think Verizon sold the SII)
You can check the switch by gently touching the physical switch (plastic cover/"button" removed) with a toothpick/pen/etc. As a "snap-action" switch, it shouldn't activate until you hear/feel it "snap" closed. If it's activating with a light/slight/tiny touch, the switch is bad. On my Sprint GS2, even the slightest brush against the power button caused it to wake the phone. Sometimes it would stick "on", and then the phone would reboot. I bought a new switch, soldered it in, and have no problems since.
If you don't have insurance coverage and are out of warranty, you can replace the switch yourself. Several eBay sellers offer replacement power switches for the SGH-T989 Galaxy S2. (about ten bucks)
Or, if you don't have mad soldering skills, several offer mail-in repair service as well, and most seem to have great feedback.
I am/was having an interesting problem with my SPH-L710. I was recently at the gym listening to music on my phone, and it was functioning normally. I took my phone out of my pocket and pushed the power button, but the screen wouldn't turn on. The music was still playing, so I knew that my phone didn't just freeze. There was no immediate cause for my phone to stop working (ie I didn't drop it or get it wet at the gym), although I've dropped it several times before today without incident.
I took the battery out of the phone for a few minutes and restarted my phone. The phone turned on normally except the screen wouldn't turn on. I called myself from my landline and used the normal gesture to answer my phone and confirmed that I'm able to receive phone calls and that touch controls are working. I also tried booting my phone into both the recovery and ODIN download screens. I'm not sure if I successfully booted into those modes, but I do know that my screen didn't turn on when I tried to boot into those modes.
I took the SD card out of my phone and activated my backup phone through the Sprint website. I tried resetting my SPH-L710 after deactivating it, and the screen was functioning again. I reactivated my SPH-L710, and now it appears to be functioning normally. I have no idea whether taking the SD card out or deactivating my phone actually solved my problem or if it was just coincidence.
My ROM is MD4 with root. I have Team Win Recovery Project v2.5.0.0. My phone has been nagging me to install 4.3 for a few months now, but I haven't gotten around to researching updated ROMs yet.
My phone now appears to be functioning normally. Has anybody experienced anything like this before?
So i have a weird problem with my note 2. For some reason the phone has no sound whatsoever and when i try to make a call or play sound the phone shuts off or freezes. Also when i turn the screen off after 20 seconds or so the phone will not turn on unless i pull battery and power on.
Started after i pulled the battery last week while phone was on went in to replace the vibrate motor. After i booted touch became super laggy, system kept crashing. And phone kept powering on then shutting off after full boot. Probably a dozen times. Ended up damaging my sd card in the process. I've re flashed a few roms and nothing really helps. When i'm in recovery the phone is fine. I've wiped everything a few times also. Currently on 4.3, I was running sky note F1 update 3. I've tried stock, meanbean and even slimkat 4.4.2 but no success. I swapped my board out into another note 2 to see if parts were defective and still have same issue. I havens flashed a bootloader yet though don't see how that is going to change anything. Anyone have some input or help with this would be great.
Thanks.
Hi,
I installed the cyanogenmod 11 nightly like a week ago on my galaxy note 2 and all was running perfectly until this morning.
When I woke up this morning the phone screen was black. The phone is actually working, I can hear emails notifications, phone ringing etc.
The buttons light up when i press them. When I connect it to the PC I can browse the phone contents etc. All seems to function except the screen.
The battery is charged. I tried to remove the battery for a long time and try again but still nothing.
I can't get into recovery or download mode as the screen is blank (sometimes there is a like a weird area at the top where there are like different colored pixels present). I know people will say the screen might be damaged but last night before I went to bed it was all fine, the phone was placed on the table, and this morning when I picked it up screen is blank.
I want to flash back the stock firmware. However I can't get into download mode in order to use Odin. Is there any other way to get into download mode or hardware reset the phone?
Any suggestions are welcomed.
EDIT: The touch screen also seems to work when I touch it as I can for example call numbers for which I had speeddial scortcuts but it is still completely blank.
I think this is hardware issue. You must replace the screen

Yeah I think so too. I've sent it to Samsung.
It was rooted and had cyanogenmode so probably I have no warranty
However I managed to install stock ROM so hopefully they won't (can't) notice.
