Screen wakes up from sleep/standby by itself.

Hello guys, I'm interested in buying a galaxy note from somebody, but it has a problem. The screen wakes up from sleep by itself multiple times. From what I understand it turns on, then turns off, a few seconds later it turns on, then off.
I've seen this problem on other forums, and some answers include turning off/uninstalling some programs, but the guy who owns the phone said he restored to factory default. (The phone is rooted.)
Is this a fixable problem? Is it a big bother to stop me from trying to buy the phone? Is this a hardware or software? Did anyone have this problem and fix it? Thanks.
Ah poop wrong section (supposed to be in the Q&A right). Had the wrong tab open, sorry.

You could try cleaning the use port. Maybe the phone thinks something is being plugged in

I have had this problem, but it only ever happens when you turn the Note on while on charge. If you disconnect before turning on it never happens. No idea if that helps, but that is my experience.

i had this same problem and it was caused by go weather app because it wasn't able to access the internet for some reason..
i reinstalled the app and it solved the problem..
i have included a screenshot of night time usage when this problem existed.i did not use the phone during the entire 8 hours..the phone was acting by itself..

Thanks a bunch for the answers guys, some new answers I haven't seen. I bought the phone, so hopefully if it happens I can fix it.
Just in case somebody else is looking for the same answer (since it's a rare problem), some possible answers I've read on other forms (haven't tried any of these):
1. Clear cache/memory from the task manger.
2. Check apps. that connect online (including widgets), and disable/reinstall them (like what johnvarghese said). This might happen with there is no wifi. (Also check which apps might wake up your phone from sleep.)
3. Somebody (on a random forum) told me to turn on the GPS.
4. Some applications can be used for locking/unlocking/ or disabling other programs/ or turning of wifi when the phone turns off, not sure, more info. could be found if you google search.
Again thanks a bunch guys.

Congradulations on your new phone. Ive been a happy note owner for almost a month. On stock 4.0.3 just root. The problem ur refering to dosent seem to me as a problem, my note and nexus s have the same issue and a few friends owners of android devices get the same "behaviour" whether on ics or gb. When i look at my battery stats, during the night the phones battery usage is literally a flat line but with many wake ups in the screen. Above a user posted a screen shot over an 8 hour period with massive drain. thats not normal. you shouldnt worry yourself as long as your battery is holding up properly.

Thanks a lot I'm really enjoying this phone the more I know it's features. I'll probably stop using my Acer a500 tablet and my laptop. I don't know whether to install a custom rom or not I'm afraid of bricking my phone. Also Swype is awesome.

better battery stats, helped me alot.
i had same problem.

I had the same issue,
in my case, mp3 downloader's ad Notification was waking up my screen,
I found it out by using app "Wakelock detector" GooglePlay Link
you need to check for "full wakelocks", check the screenshot

Screend issue resolved (Culprit:- Facebook locked by Applock)
I have locked facebook app with 'Applock software, which was causing the problem.:crying:
Now I have removed Facebook from 'Applock software list.
Now it is working fine. :fingers-crossed:
P.S. other application are still locked by Applock software:good:

Xperia Z1 issues

Guys I recently got my Xperia Z1. And constantly I am facing issues in my Z1. Here are the issues that i am facing along with the pictures.
1. In one week I have faced this issue twice. The issue is that suddenly all the signals disappear ( I am using BSNL sim ). And when I try to register it on network an error message comes that cannot register on network. Make sure your SIM card is inserted or selected network is available. So is this issue with the SIM card or the phone? The first time when I faced this issue I manually registered it on network and it worked. But second time when I tried to register my SIM manually nothing happened. So I had to restart the phone. And the issue seems to have disappeared.

2. I faced this issue yesterday. When I tried opening the camera app (default app) this message popped up. I tried reopening it many times but no success. Only after restarting the mobile I was able to open the camera app successfully.
3. This issue also happened yesterday. I was playing a not so graphic intensive game. Played the game for around 10 min or so. Then I stopped playing it. I checked CPU-Z, about 5 minutes after stopping, for battery and other information and noticed it is showing battery health as overheat. I checked this coz my phone gets quite hot if I play game for sometime. Is it normal for a mobile to get overheated just by playing a simple game for 10 mins?
4. Today I noticed that there is a slight yellow hue present when screen brightness is minimum. I compared it with my Nexus 4, this too with minimum brightness, and the difference was quite evident that there is a yellow tinge. Maybe it is not evident in the pic I am attaching but it is quite noticeable in reality. So wanted to ask whether there is really an issue or not.
Hoping to get my doubts cleared as I never faced such issue in a week old mobile.
Thank you

Are you on a rooted phone using a custom rom?

I suggest you to reflash your phone with Sony Update Service, that will fully reinstall your Stock ROM, save anything u need because that will wipe all of your datas.

Note 3 on Android 4.3 won't enter deep sleep!

Odd bug I found on my note 3 is that the phone will sit at 300 Mhz with the screen off all day without entering deep sleep
It will only do this on WiFi though as soon as I turn it off Deep Sleep will function as it should.
I have the NB4 firmware and Bootloader, Android 4.3.
I am rooted and I have Xposed Firmware installed, anyone else have this issue?

Install wakelock detector.
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
It will tell you what's waking your device. But I'm going to guess you have location services on.

I have the exact same problem. It's a month now and I didn't change my wifi router or anything.
There are no apps directly causing this. I will inspect kernel wakelocks and report back. But I bet that some app is doind something that causes "android system" to wakelock the cpu. I have many apps so it will be very hard since none of them have any battery drain out of the normal usage.

Turn off "Always allow scanning" in wifi. (Menu/Advanced.) Scanning wakes the phone, and the normal scan interval is 5 minutes. (It'll still be scanning when you're in the page showing the available connections. You are in there to look for a connection, right? No one would ever be in there for any other reason. (No, Bill Gates didn't say that no one will ever need more than 640K of memory.) IOW, it's going to scan whether you need it to or not if you're on that page, but it stops as soon as you close the page. (Even though there's a Scan Now button. Come on, Google - next time, try thinking. Just a little.)

Hmm nope.. I think something else was corrupted somewhere.
I tried this:
Code:
adb shell pm clear com.android.providers.settings
adb reboot
After setting the main settings again, the phone is now much faster and as of now the problem didn't show up.
I'll keep you posted if it happens again. If not, this could help many many people.

Confirmed: the problem was totally solved.
I suggest anyone with the same problem to give this a try and do not restore the main settings from a backup.. but just set again the home and lockscreen or any of the main settings you need.
I think something gets messed up with intensive use or tests. This apparently cleans it.

A friend of mine had his Note3 very slow and draining battery very quickly after the last OTA update. With my "method" his note3 is now back to normal.

I had the same problem, the phone was at 300 Mhz with the screen off all day without entering deep sleep mode.
All I did was changing the wallpaper to the default one !!!!
Ploblem solved.
Very strange ....
I tried it 3-4 times (switching wallpapers from default to another one downloaded from the internet) to make sure that this was the problem.
At all times the problem came back and disappearing.
Note3 n9005, stock android 4.3, No Root.
Thanks Zibri !!!
ps
How can I try this without root ?
Code:
adb shell pm clear com.android.providers.settings
adb reboot

Sound, Flashlight, Vibration, Camera NOT WORKING AT ALL on my HW P30 Pro

I am using P30 Pro VOG L029 9.1.0.168
Yesterday I was driving and using GPS when suddenly everything goes silence.
1. No Sound (even Music was playing but muted)
2. No vibration at all (even the usual vibration when I turn on the phone)
3. Camera Can't be open. No error message whatsoever. (it's blinking black one time like the camera was running but nothing happened.
4. Even flashlight is dead. (when I press, there is the blue ring light up around the flashlight icon but no flash), and no error message here also).
I haven't tried factory reset yet, because O dont have a chance to backup my files and photo yet.
I have tried running on safe mode. Still same thing happen.
And NO, I didn't drop the phone... I am using UAG Plasma Casing BTW.
What should I do?

hi can i know have you settled the issue?

Hi, I wondering if you have any solution about this issue ? That is exactly what is happen to me

To everyone with the same problem, follow these steps:
1. Drain the phone's battery
2. Leave it on that state for 10 minutes (an hour, just to be sure)
3. Open it again
Phone should start vibrating and playing back sounds now.
Should also fix the camera and flashlight issue.
Your welcome.

Drain the phone's battery until 0?

Exact same thing happened to me on my P30, after a couple of weeks things got fixed on their own. A few days later the flash and the speaker sound went off again, and the cam and vibration kept working .. how weird is this issue !!!

You cant drain the phone's battery until 0, because the phone turns off at 2%

Hi, I know is a old thread but..
I have followed this method 3 months ago and p30 started working again.
Yesterday I had again the same issue but this procedure did not fix anything: camera, flash, vibration and sound don't work.
Do you have any raccomandation?

I've exactly the same problem on my P30 Pro, plus battery drain, heating and slow startup. Tried all the apparent fixes, the above, safe mode, clearing system cache, all with the exception of a factory reset.
Help!!!!

Active Edge stopped working randomly

Hello everyone, I'm having issues with active edge. You can squeeze for assistant or silent stuff. But it stopped working for me whenever the phone is locked. And it'll start working again when it's charging. It stops working again when it's off the charger...
Steps to reproduce:
1. Ensure your phone is not charging
2. Try squeezing for assistant, if it works then let your phone go to sleep and lock (5 sec default)
3. Unlock your phone and try squeezing again
4. If it stops working, put your phone into charging state (wireless or wired), and it should start working again until next sleep
Let me know if you have the same issue too? I'm on the Feb update btw.

Can't replicate it here. Still on the January update but about to install February.

Update:
I found out that "allow when screen is off" is causing the issue. Turning it off and active edge is working now (when screen is on). Perhaps Google can fix this soon

Thanks for replying. Hopefully a factory reset would fix the issue.

I just factory reset and the issue still persists. Just so anyone else having the same issue know this.

Mike does something similar. I sometimes unlock the phone and the active edge does not work. Then I push the power button to lock the device, then unlock and it works fine. Can't really figure out as it's random...it doesn't happen every single time.

Exactly the same issue! It works fine after I turned off "allow when the screen is off". I never used it with screen off, since the screen turns on whenever you lift the phone, or when it detects movement.

Hey guys just a last update: I managed to get it working by reflashing the factory image (not OTA)
