[Q] Accelerometer turns off - Galaxy Note II Q&A, Help & Troubleshooting

Is there any way to force the accelerometers to stay on when display sleeps?
I'd like to use apps that require accelerometers to work even when screen is off, such as accupedo and "Zombies, Run!" (on a treadmill).
Currently it's not possible since they stop working when display goes to sleep.
Any way to fix this?
Thanks in advance!

Screen Standby
Okey so a temporary workaround can be achieved by installing Screen Standby from Market (root).
I believe this could probably be achieved by patching the kernel since it's likely a config option (works as I'd like on the sgs3).

[Q] Force WiFi to stay active when screen is off?

Hi everyone!
I'm using OpenDesire 4.0.4, and while it's more or less the perfect ROM for me, I'm getting a little annoyed at the WiFi. As the ROM is based on CyanogenMod, it has the same WiFi behaviour: When the screen turns off, the WiFi enters power saving mode, regardless of the apps that are active at the time, or the amount of traffic over WiFi at the time.
The problem here is that any application that's using WiFi pretty much just stops as soon as you turn the screen off.
1. Sipdroid during a call: Massive packet loss as soon as the screen turns off. You may hear a garble or two, but nothing intelligible.
2. SwiFTP and other FTP servers: Connecting to the FTP server and navigating to folders takes ages when the phone is in standby. Transferring files is more or less impossible (times out)... Everything's fine when the screen's on. If you transfer a big file and turn off the screen during the transfer, you basically pause the transer - turn the screen back on and the transfer goes back to full speed
3. Market: If you turn off the screen while a lot of apps are going to download, like after pressing "Update all" for a few apps, more often than not they'll just fail in the background.
Now, I could beg and ask the ROM developers (Kali for CyanogenMod on Desire, or AdamG for OpenDesire) to just change this behaviour, but it seems that most people are happy with the situation, as it causes the WiFi to use very little battery on standby... so I'm asking if anyone knows how I could change this myself. Is it even possible to do this at runtime without baking it into the ROM directly?
Or am I SOL until (or rather unless) AdamG or Kali takes pity on me?
I'd love to hear some input - hell, maybe I'm just doing it wrong ... Thanks in advance!
PS: Yes, my WiFi Sleep Policy is set to Never, and the Desire DOES stay connected when the screen is off. Just in a very low power mode...
-edit- Should have searched, sorry: http://forum.xda-developers.com/showthread.php?t=752856
-edit2- Looks like there really isn't a fix for this... Anyone found a way to completely disable PSP on the Desire/Nexus WiFi?
I'm on the same ROM as yourself. What value is your "screen-off lock screen delay" set to?
In my observations, the transfer in the state you mention still persists albeit at a very slow rate and the WiFi chip is certainly placed in the LOW power state, although on.
I'm unaware of any workaround but what I use myself when transferring bulk 1-7GB files through WiFi from my PC/Laptop, which is to change the value of the screen lock delay at screen off under Settings>OpenDesire>User Interface>(last option) to a high figure, like 10-30m, depending on how long I'm expecting the transfer to take. It's a trade-off but you'll still save over 95% of the power since your screen is off but the WiFi/SD/CPU remain working as when the screen is on. Maybe you've tried this already?

That's not a bad idea... brb testing .
-edit- Didn't work
As soon as the screen times out, my transfer speed drops to nearly 0 - even with the lock delay set to 30m... :'(
OK, that's confusing. I'll be back by tonight or morning... I have much testing to do on this since for sub-20mins, my connection runs plus 200Kbps according to the PowerTutor log in such a state. Usually it would drop to 0.3-8Kbps when the screen switched off.

Mine drops to practically 0. So low that due to overhead, FTP transfers pretty much stop completely...
I've seen that the linked kernel module provides a temporary workaround for you guys now. During the course of my testing your concern I basically found my WiFi module isn't ever turning off nor switching any connections off - it's always awake and can always transfer some data. Even in the LOW state it is connected at 24Mbps. Whatever I did I couldn't change this behavior on 4.0.4. Time for another wipe...
OD has many user preferred options baked in working fine alongside the conventional options so it'd probably be best suited for a toggle of this feature to be implemented for you guys (if at all possible). Not sure if that WiFi module power state behaviour is write-able and changeable on-the-fly before a reboot, should be, as it's only changing a hardware state.

The new Wifi module is working perfectly here. No more performance problems, and my power consumption has actually gone DOWN. Probably because I have a bunch of connected apps running in the background and PSP is very inefficient for that.
Also, the delays in Chrome To Phone and Appbrain web installs are gone...
I'm loving this fix...

FRX03...GPS...Sleep Mode...

I searched for Sleep Mode and GPS problems, and of course since those are very common words in most posts, I was having a hard time actually finding if anyone else has my problem.
I am running the most current kernel of FRX03. I have a sprint Rhod400. This problem pre-dates the current kernel, and I am not sure how long it has gone on, because I was having a lot more issues with sleep mode back in the earlier kernels anyway, as I think all people were. I am running with sleep mode set to 1.
Whenever I start a GPS program, usually it is foursquare, when I kill all the apps including foursquare using Advanced Task Killer, the phone will not go back to sleep. I have also looked at the "running services" setting and nothing is running besides Android. It seems to me the GPS stays active even though the GPS icon and all hints that it is actually running ceases to be found. I am guessing this is causing the phone not to go back to sleep. I have not really tested it out with navigation or maps to see if it happens there also, but if my memory serves me right it does.
Any suggestions on possible fixes?
Disable GPS. It's a known bug, which has already been filed on the bugtracker.
If GPS is enabled, phone will not sleep - and I don't mean enabled in that there's the GPS icon in your notification bar, I mean enabled (checked) in Location & Security. Uncheck it there, and the phone will sleep.
This is all interesting, because my RHOD400 seems to sleep just fine (much of the time) with GPS enabled!

Enable GPS, then open an app that uses it. Leave GPS enabled, but close the app. Now try to put your phone to sleep .
I've definitely seen intermittent issues with sleep and GPS. Not sure if it's every time, but I noticed when the phone doesn't sleep, I disable GPS in loc&sec and it'll go to sleep.
The only other serious sleep-related problems I've had is with rogue apps stealing processor cycles and keeping the phone awake.
I'm running NAND were pm.sleepmode = 1.
Yesterday I left my GPS enabled and I seemed to be getting better battery life? Maybe it is just a fluke... But you never know!
I will try it on my other phone running HARET.

Well better battery life is probably related to usage.
However, that would be interesting if on NAND the GPS no sleep bug is non-existent...
I honestly haven't tested it in a while. No one has specifically looked at fixing it. I guess it's possible a commit happened to fix it - just usually doesn't work like that .
I use the 11/22/10 XDAndroid build from the .cab and the bug is present. LED doesn't turn from orange to green until I turn off GPS in settings and turn off the screen.
He probably thought that it was sleeping because the screen turned off (I used to think the same thing).

No I knew it wasn't sleeping. I know the purpose of the LED being on always(sleep mode debugging). I was just trying to figure out why, and if there was a fix, which there isn't. In the earlier version of XDAndroid builds it was more than just GPS that was causing sleep issues, so back then I didn't think much of it not going to sleep, as I couldn't get more than about 4 hours of battery life out of those builds anyway. Now I am getting at least 12 with heavy usage and way more than that with light usage. So things have improved indeed.

Indeed! So that is the fix - disable GPS. It sucks, but it's on the punchlist of things to fix. Unfortunately I don't know of anyone looking at it specifically at the moment, but I'm sure it'll get addressed.

Tab S 8.4 ramdomly sleeps??

Searched the forum and did some google searches but only came up with one thread somewhere else that never went anywhere. This may be glitchy apps (although I have both on my Droid Maxx as well with no issues) but I thought I'd ask anyway.
So the problem is the tablet(SM-T700, Android 5.02) will seemingly go to sleep while actively using an app (so far it's common in 8 Ball Pool and has also happened during Beach Buggy). I don't know if it's app related or a setting somewhere. I have power saving modes turned off (as well as auto screen brightness). Anyone else experience this?
Well it may be a combination of the app not telling the screen to stay on (twitch app had this issue for about 3 days then it got an update) any you having the auto screen off timer set too short.
The permission used is under others and is called quite simply (prevent tablet sleeping). With out that mode set if you do not touch the screen in (insert screen shutoff timer length here) the tablet will turn the screen off to save power.
Thanks, I'll check that out. I'm going to run a few more apps and see if it happens with them also.

GPS/Location lost when screen is off??

Hi!
I used to have no problems with this situation on any of my previous phones:
In apps that uses gps, like runkeeper, i get very fast gps lock.. but, then, once I disconnect the screen, the "location" seems to be turned off.. The gps track stops counting. When I turn the screen on again to check what is happening, the phone instantly gets gps lock and registers that new spot. Basically what happens is that I will get a track but, instead of having the full track, I only get "straight" lines between the points the gps locked when i turner the screen on to check what was going on..
I have the location in high accuracy..
Any ideas?
Thanks!
I have the Impression there is a different location provider for the new chipset. When i am at places without any gps signals (for example a tunnel) the reported location is moving with the same speed and direction i had before coming into the tunnel. There also a change in my Google location history. When the screen is off it looks like the location is provided by phone cell only. The reported location is more than 300m away from my real location. I have not seen this in the same locations with my older phones. (Edit: All with Oyxgen OS 3.1.2)
I have the same issue as op on 3.1.2, not rooted.

I have this stupid thing also, stupid phone,
The gps loses the fix right after you leave the app that uses it. It doesn't work in the background, I'm gonna have to return my phone sadly.
So does this happen with the newer firmware? Can you put it in the background with the screen on and it run? It seems like a software issue more so than hardware, maybe I'm wrong but who knows..
Sent from my SM-G935T using Tapatalk
obviously a software issue, but they won't fix it since nobody talks about it. If you switch to another app that doesn't use GPS or turn off the screen the phone loses the fix right away.
Still happens with Oxygen OS 3.2.0
Can you give a try launching a nav session in google map. On my lg G2, when I get a fix in google map then turn the screen off, I will loose my fix. But if I launch a turn by turn nav session I will keep my gps fix even if I turn the screen off.
Could this be related to doze hibernating Maps or whatever app /?

Yes. This is likely related to the aggressive Doze mode that has plagued users in receiving notifications. Try disabling Doze by following the instructions in the link below and try GPS again. If it works, then Doze is the cause.

Turn off power saving mode for using GPS while turn off screen
I have used Strava and it can not be received GPS signal when screen off. Then I turned off power saving mode and it was OK.

its dose feature that's interfering. I had the same issue. disabling dose does the trick.

And this is why I make my rom that disables doze all together. It kills battery more then it saves.

Wake up on plug

Hi guys,
does anyone know a way how to enable wake up on charge on an S9 (G960F) with OneUI 2.0 (aka official Android 10 ROM)? This has been the default behaviour prior to OneUI 2.0 upgrade - I believe all Samsung phones did that since like Android 7.x. But some people seemed to dislike it so they removed it now.
So far I tried Routines (Good Lock module) with no success.
My use case is to put a sleeping phone to a Qi charging stand on my desk, let the phone wake up automatically and then timeout back to sleep while turning on the screensaver (Chronus Pro in my case). I don't want the phone to never sleep while charging. I also don't want to use an always on display instead of a screensaver. I just want my phone to wake up when it starts charging.
nvm, its not there anymore. sorry mate, it slooks like 3rd pty apps is your fix
Well of course I need a third party app. Tasker seems to do the trick but feels like a huge overkill. Any other tips? I'd rather stick with something free.
Solved. Set up a simple macro in Macrodroid. I even limited it to daytime so it only does its job when I'm at work.
