Phone turns on my flash light whenever i hit the power button !

There's this strange problem my phone has where the flashlight is turned on whenever i hit the power button to turn off my screen It has been working fine on android revolution rom for the past 3 months then this problem started occurring just this morning. Going to the official htc flashlight app to adjust the brightness works but it cannot turn off the flashlight unless i initiate a shutdown. anyone has any idea how i can solve this problem ? is this a hardware or software issue ?

If it worked before you tried a new ROM it's bound to be s/w. Is Tasker baked in to the ROM or did you install it? Some third party app is triggering Flashlight to launch when you press the power button. You might want to check the dev who built the ROM's thread or ping him or her.

In aokp there's a turn flash light on by hitting power option in the settings have a look at your roms settings.

this rom isn't exactly new its a 3 month old build and has nv given me any sort of problems before till this strange problem started occurring. Is there any way to disable the flashlight for good so it doesn't keep turning on and draining my battery ?

If it were me, I'd want to figure the problem out as what's causing it may not be limited to Flashlight (EG: other things are being turned off or on and you just don't know it). I you want to disable it, go in to Apps>All>flashlight and clear data, force stop, and then hit disable.

Do you have EQS? If so, try to turn flashlight on then off again from the EQS tab itself.

Extended Quick Shortcuts. The ones that show up in a seperate tab in the notifications panel.

Have you solved this? I am having the same problem. Wondering if it is a little virus or something.

Try freezing the flashlight app

its software related.
i m using viper rom and it has the option to trigger flashlight when power button is pressed (while screen off) . ive enabled it. so yea, you can disable it as well.
so check that.

Well if you're on viper it's an option for flashlight.. You can change in venom tweaks...

man, that's already the 3rd if not 4th thread abut this issue, one being opened by myself...
glad that I'm not the only one...
at beginning I thought it'd be a faulty/bent usb connector, as experienced by others, but since I am redaing of others with the same problem after upgrading, then it cannot be...
have you install;ed the OTA or started from cratch? have you cleaned dalvik cache? (I did with no avail) do you see a pattern in your wakeups? is it every x minutes? is it at random?
as regards me, it happens also when wifi and 3g and sync is off (but 2g on, that is I can only receive calls), so it cannot be anything related to signals...
I have installed BetterBatteryStats and will be sending a couple of resports to the developer trying to see if he can understand what is going on and what wakes up the phone...

I did a completely clean install... Wipe data and cache... Installed the OTA rom available on developers section.
Do tell me if you are able to find a solution.

Check this bugreport:
https://code.google.com/p/android/issues/detail?id=39829

Yeah, the same thing happens to me. VZW Toro. Stock AOSP Rom. I think it's related to daydream. It didn't start happening until I enabled that functionality.

nope... daydream is off on my phone

It seems to be an issue with the WeChat app:

Dunno, but follow the issue on that link. Answers ougta be there soon...

I do use WeChat .. let me delete this application and check ...

I don't have wechat and the problem is there so no it's not wechat

I am in the same boat, Thegios.
No Wechat... No Daydream.
I have noticed my screen waking about every 10-15 minutes. It only happens when connected to my Wifi. My N7 does not wake at all. I have wiped the Cache and noticed my "Android System" hogging my battery stats.
I am trying to search what Apps I have settings for something like "sync only on wifi"... from there I should be able to find what is turning the screen on. I have BetterBattery Stats installed, and am trying to dig a little deeper there as well.

cant b wifi, , mine wakes up also when wifi is off and 3g is off and sync is off
I have tried with bbs as well but found notjing wrong

i've read all the reports of bugs, and the people with issues seem to have flashed the stock AOSP rom.. i dont have any of the issues described and the way i installed 4.2 was first flashing the takju 4.1.2 with nexus toolkit and then i got the 4.2 OTA from "about phone"->update.. oh and i have daydream activated.

For those of you with high android system usage, are you downloading music from Google pay music for offline usage? I did and I got this sudden increase. this has never happened to my phone before. Maybe Google play music needs update?

My problem is resolved by removing WeChat and daydream disabled...waited for like an hour and confirmed about the problem solution that worked for me.
You can try disabling that sleep mode apps in Apps settings.

Your problem may have been resolved but wechat and daydream is not the solution to this as many of us aren't using either and still having this issue. I think I'm going back to bone stock 4.1.2 and going to let the OTA upgrade me to 4.2 and see what happens.
wechat is NOT the solution people, as the Google Code page suggest this is a sync issue that could be caused by a number of apps.

Sorry to report this but my phone has been bone stock since I bought it, got the 4.2 OTA, not using wechat or daydream and I still have this issue.

Screen turning on by itself

When I press the power button on my phone and put it down (whether it be a few inches or a few feet away) it will turn itself on for no reason. I have installed various air-push detectors, I have tried cleaning the USB port (note this phone isn't even a month old in my hands) but nothing is working. If you know what's going on and or how to fix it let me know. I'll post updates if I get it fixed.

I've had that happen many times and even after running a logcat I've never figured out what caused it. Sometimes an app requesting su has been the culprit but most of the time I have no idea.

So you never fixed it? I'll try auto granting and using logcat

i disabled the alarm and as soon as i was going to say it might have worked, i turn my phone off and literally a second later it turned back on

well in that case you probably have to disable one app at a time and test for a day or so to figure out which one causes the wake up:banghead:
my screen on returned with the enabled tunein alarm option. i wrote them a support ticket and hope they will adress that issue as fast as possible.

Yep, it's an app causing the issue. AudioGuru used to do it to me (whenever it changed profile the screen would light up). Since the latest version it no longer does it

it is caused by an application. usually caused by live wallpapers. install dr.web antivirus scan, remove suspicious app. :good:

[How To Fix] Strange things happening to my N7100

Hi Here is bunch of things started happen without reason and cant find fix.
1. Gallery app freez for over a minute and crash if the phone is connected to wifi, but works perfectly if connected to 3g or not connected to any thing.
note: i unchecked photo sync for every account because i noticed that when the gallery freezes the wifi traffic is too high
2. Homescreen picture changes after making or receiving calls from certain contacts .

It's interesting that you mentioned this-I have been having a weird wifi hang lately and twice I have had the home screen wallpaper Change on me when it happened

Whenever I reboot my Phone it asks me which launcher I wish to use. Even if I choose to always use adw.
Anyone knows how to fix this?

hi thanks for taking interest in to my thread
When exactly the wifi hang , because i noticed that when the phone is waking from a deep sleep the wifi takes about 5 to 10 seconds to get back to full signal .
Does the wallpaper changed after you received or made a call?

hi thanks for taking interest in to my thread
try to clear the launcher defaults then restart and then select the adw to be default.
the idea is to restart with the default cash clear. it may help , tell me if it worked.

My wife uses different ring tones for different contacts. The problem is that every now and then it defaults to the main chosen ring tone and have to set them again. I was wondering if any usual updates to apps may be causing it.
Anyone else with this problem?

May be that happens when she plug the phone to the pc to add or remove media . The media scaner that runs after she unplug may cause loss of assigned ringtones. If that is the problem try using airdroid from the market its free very easy to use. If not try to know when exactly that happens .

Thanks for the quick reply. The phone has never been physically connected to the pc. Only connections are via Bluetooth to transfer photos etc. Will check next time if anything changes after Bluetooth connection though.

I can't remember, to be honest.
My note is set to disable the lockscreen when wifi connects to certain WIFI routers. (work/home).
I suspect that might be the problem, but I can't for the life of me remember what program is turning on/off the lockscreen.
Never seen any issues when getting/making calls.

Strange thing: if I choose touchwiz to always open as default then reboot it doesn't ask for launcher again. If I choose adw it asks every time I reboot

[SOLVED] [5.1.1] Screen freeze

EDIT: Thanks to @gewa2001 for the solution. Apparently, the Smart Manager app is whats causing it. If you're not rooted then try to disable it or if youre rooted then you can just Uninstall or Freeze it with RomToolbox and it should fix all the screen freezes.
So i just recently installed the N750XXUDOK5 Firmware for N750 on my Indian variant of the phone. Everything seems to be working just fine except i've been experiencing some screen freezes. Like, it just so happens that im using something and it just suddenly freezes for 4-5 Seconds and then starts working fine. And it happens quite frequently so its kind of annoying.
Also, i dunno if its related but i've noticed it usually happening when i receive a message on whatsapp, just as i get a message a bunch of whatsapp icons pop up on the status bar and then merge into one which then displays a Heads up notification and causes the screen to freeze.
Is anyone else having a similar issue/ is there any way to fix this ?

Same here: occasionally system slow or even frozen since 5.1.1 (no factory reset, but debloated and rooted). Mostly on lockscreen, around twice a day. I switched off the new "app optimization" feature in the new 'Smart Manager' today. No more screen freeze since then. What's YOUR observations?

How to switch off 'app optimization' within the SmartManager app (I got the German language version, so your tags might be called slightly different in English language) : tap on the 'battery' quadrant, then on 'details', then switch to 'off' by using the upper right on/off slider.

Aha. For some reason the Smart Manager app on my phone doesn't have any sliders but i froze the app via Rom toolbox and the rom seems to be not freezing anymore
Guess thats what was making it freeze. Thanks!

I just removed the samsungs weather widget from my homescreen and it reduced the lockscreen freezes to almost 0. If i put it back on homescreen and turn of my device and wake up after 1min, i was getting serious freezes and this helped me a lot.

I froze smart manager using titanium back up but occasional freezing up to 5 seconds still occurs. Will try uninstall.

Just flash the rootable kernel for 5.1.1 from the xda forum and u can root as well afterwards if u want and then no screen freez will iccur. This is the sole method for removing and such issue. Flash THAT KERNEL. THATS IT. no other remedy will ever help
