Hello everyone!
We have an fleet management app that runs continuous background updates every 1 minute using an Android service. We are seeing that sometimes the devices are failing to receive new GPS locations, and continuously report that they are at one location, when they are actually somewhere else. You can imagine this doesn't work well for a fleet management app. Rebooting the device seems to rectify the problem in the short-term. It also doesn't happen on every phone, even if they are the same model with same fw.
Any ideas? Thanks!
For those that have had issues with battery drain like I did, I may have finally found the solution.
After much research and reading many threads I found that the culprit was google play services. Specifically it was Google (I believe on Now) always trying to figure out location.
It always does a quick wifi check to try and figure out what's what. However due to a bug that has been in the coding since launch of KitKat (hurry up and fix it google) it fails and will just continue to try and try and try.
Solutions I found were to turn off location access on phone or edit Google Play Services Permission, specifically disable stay awake permission.
Turning off location, google now access to location, or both resulted in temporary fixes and I believe google still tried to figure it's location via wifi despite being told not to.
Long story short...if having just wifi location doesn't work.. and having location off doesn't work...
Then why not switch mode to high accuracy in which GPS is left on!
Google uses GPS for location, it works in one try, everyone is happy!
Long story short, if you have KitKat and are experiencing high battery drain with you phone constantly awake when off.
Switch your location settings to High Accuracy. Phone is smart enough to not use GPS when not needed.
It worked for me and it might work for you too!:good:
(Hopefully this fixes it for good)

its working bro......cheers......:good: great ........
So usually I just keep GPS off to save battery. What your saying is to keep GPS on with high accuracy may actually improve battery life over keeping GPS off altogether?

what about device sensor's setting?
hi all
is there anyone here already try AppOpsXposed? http://forum.xda-developers.com/xposed/modules/xposed-appopsxposed-appops-4-3-t2564865
it's work at My desire 601 kitkat 4.4.2 without root
this apps can disable hidden system location and other thing but not sure work or not but so far my battery getting better now...
I have the same problem but the solution doesn't work.
I think you fixed the problem by charged the phone and not with switch gps (see your graph).
My solution now is only reboot.

I have GPS switched on. it just doesn't keep it running google play services will turn it on as needed instead of trying to get location from wifi and locking up even when told not to.
Different people have had luck with different solutions and this was mine.
Here are my results from today, the first small block of awake is from me Listening to music for about an hour on 4G.
Not sure what the second block is, might have been apps that updated or the bug returning for a couple minutes. (battery was at 45% at time of pic)
Thanks for this! I'm going to have my wife give it a try!
Hi all,
this is my very first post here on xda, so please forgive me if this is not the proper section for my thread. I searched for other thread about similar issues, but I didn't find anyone. I'm Italian, so I even hope to not being wrong in English writing.
I recently bought (on November 2014) an Huawei Ascend Y550-L01 (Android 4.4.4, EMUI 2.3, ROM B137), coming from a (Portuguese) Samsung Galaxy Y Pro GT-B5512. Soon I experienced a very strange GPS behaviour: GPS turns itself off. No problem in signal fixing, nor in quality or precision. It simply deactivates.
First I noticed this using the OruxMaps app (which works fine on many phones, even my old one), simply recording the track. Indeed, at the beginning the app was being killed (because of the integrated task-killer) when screen was off, but after setting it as a "protected" app, when I record a track, GPS works while screen is on and, if screen turns off, then most of the times (not always) GPS is deactivated from within Android settings.
I even received (from the purchasing time) some GPS errors while in the home screen... I don't remember exactly that error, but in a fast Internet search it was told being caused from the weather widget, precisely from the "actual position" setting. I deactivated it and added manually my town and those errors were gone.
Then I noted another strange behaviour: GPS turns off even in standby, during night. It is on "extreme precision" on evening and it's off at morning. Sometimes I notice these deactivation (in the notification menu or into the energy saving widget) while I'm using the phone (but always when screens is off), without any error or message popping out... It simply gets deactivated.
Any other experiencing this strange issue? What could be the cause? I sent a mail to official support, but they asked me to take the phone in a service point... I can't stay without phone, so I would like to avoid this if it's not strictly needed.
I think it's a ROM issue (said that even in the mail), but unfortunately still there is no alternative one (or at least I found none). I think also that (almost) every app that uses GPS suffers for the same behaviour I faced using OruxMaps.
PS: phone IS rooted by a couple of week, but I'm facing this issue from the first day.
What the hell is going on? Any help, idea or trying suggestion is appreciated...
Many thanks!
Up?
I also see strange problems on the Y550-L01 connected to GPS.
In my case the GPS does not disconnect completely, but during car navigation the signal gets lost from time to time (tested with different navigation apps).
This is only the case when the Y550 is NOT connected to the charger. If I connect it to the power supply, GPS works quite reliable and accurate!
For me this sounds like a software problem (maybe connected to a power saving mode?). I hope a firmware update will fix this soon.
Even to me this is a firmware issue. Before of your answer, I was really beginning to think it's a fault of my phone. Now that I'm not the only one, I went back to think of a bug.
If it is a power save problem, then try to use this app to stop the power save mode :

(ultra light : 35K, free/no adds)
"Wake Lock gives you control over the Android Power- and WifiManager.
For example, you can force the PowerManager to keep the screen on or have the CPU still running in standby mode or make sure the Wifi connection keeps running at full performance.
You can use it on any android phone or tablet.
Use it to keep the screen on in full brightness or dimmed mode during movies or slideshows.
To make sure the CPU is still running in the background doing your tasks when you press the standby button."
Thank you for the report.
It seems that the new huaweï G620S has the same GPS problem :

Any news of an Huaweï update ? Hope yes...

Hi! Better post your question in our small Huawei Ascend Y550 thread. Maybe there someone of us can help.
If you understand German:

These folks have the same proplem, but no solution.
Try it while a charger is attached.
Hi,
If I'm the wrong forum I apologize and would be happy if directed to the proper one.
Androids newer versions have changed the 'GPS' button into a 'Location' button which now offers 3 options for determining your position (recording wifi router information and comparing it to a google database, using the devices GPS, and doing both) each of those options prompt a disturing and annotying popup each time you turn the GPS on, "advising"/badgering the user into sharing his information with Google.
The only solution which I found to this popup problem (without installing any 3rd party apps or rooting the phone) involves disabling the Google Play Service- that however created something strange which I'm not sure about... If previously the user could choose which way of locating he wants and the device remembered it- now every time the GPS is turned on it is automaticlly goes into "local device&wifi tracking" mode (the first option).
I want to know if a)Does the device indeed monitors that information (even if it can't send it anywhere with google services being disabled)? b) any way to stop it? c)can this default be changed so that only the local GPS chip will be used?
Thank you very much!

Hi everyone.
I work in the support section of a small software company that supplies a software suite to hospitals, we have 2 PC applications and an Android application that work in tandem. At one of our sites they have been having an issue whereby some of their devices (Motorola Moto G2, Android 4.4.2) will randomly reset the date and time to random years (1970, 2040, etc) which is problematic as our software is a real time system that requires the use of time stamps from the devices. If they don't have the correct date and time then it can impact the way the software works, to the point where the devices will no longer connect into the system. I will also note that we use an application (SureLock) to lock the phone down so that it can only use our application.
I have tried several solutions to this problem, including making sure that the automatic date and time settings are not switched on, making sure that the batteries are not completely draining, etc. but have been unable to come up with a solution and I cannot find other users who have the exact same problem.
Some excerpts from my open ticket:
"...the issue was related to the date and time on the devices changing to random years (i.e. 1974, 2036, etc). This has been an issue in the past and so they now untick the "Automatic date & time" and "Automatic time zone" settings within android and set the date and time correctly which solves the issue. But the phones are still randomly changing their date and time even with those settings unticked."
"...We charge our phones fully every day, so it would be extremely rare for a battery to be fully drained. Think it must be something else happening."
"...
Motorola – Moto G – Android version 4.4.2
Date/Time not set to automatic – but we have noticed that this makes no difference – problem still occurs whether the automatic is ticked or not.
Issue occurs on random phones and at differing times of day."
"... Problem is still occurring but not so often. I was keeping a track of when it happened but there did not seem to be any pattern. The only thing I noticed was that one of our Operators who has a cochlear implant seemed to have it happen by far the most often. Could there be some interference from the implant?"
I found one other thread on another forum but it was in relation to the Samsung Galaxy Centura, and this was solved by either unticking Automatic Date & Time or checking the calendar application's time settings. I have tried both of these to no avail.
I am at a loss as to what to try next, any help or info would be much appreciated.
