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!
Hi everyone - I actually don't know who else to ask but this issue has been driving me mental for the last couple of months. After days and nights of investigating and looking through various forums and articles, I think I can find (or try at least) the words to describe my problem more...technically))
So OK, first off the device is Huawei Ascend G510-0100 running KitKat under the Cyanogenmod platform but the issue was already present with the factory's 4.1 ROM. I thought rooting the phone, installing just brand-new everything and having a bloatware/clutter-free Android OS would rectify all the causes of this nightmare but no. I'm not the only one with this problem: Google-search the issue and you'll find numerous forum threads where users seek for a solution to this "software loophole" as well as one of my friends (Galaxy S2) and another one with the HTC One X+ so I rule out my phone's model, OS version or just my device being faulty from the list of potential causes.
So - every time I turn my WiFi off on purpose or when I go out of my house (where logically my phone looses home's wireless signal) - the location services and the app synchronization processes stumble, mess up, run into and furthermore cause internal system mess-ups from such "unexpected" losts of internet. After that I can't make a phone call, send SMS or run USSD codes (checking credit balance etc) but I can still receive calls and texts - basically I fail to reach my cellular services but the service can still reach me. Turning Airplane Mode on and then off or simply restarting the phone altogether temporary fixes the cellular problem until the next time the internet becomes unreachable to Play Services. I tried turning location and sync off, tried different location/sync options...I wish I could disable Play Services but then I wouldn't be able to use the Play Store - | tried messing around with probably every single option available and possible but the Play Services still failed me and.......I honestly don't know what am I missing and where to look next
Edit: (I never use the mobile data btw)
Any suggestions? Anybody? I'm hopeless at this point :crying:
Thank you all...

Anyone? Please...
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!
i cant talk about heart rates or sport related issues, i havent got the time to use the watch in work outs yet (if i ever get the time).
main reason i got mine was due to having access to messages and alerts without the need to reach the phone (and it aint that good, i can only read last message from apps).
mine was chinese, then flashed the stratOS rom and, now, international rom.
since i got the international rom, and updated to last version, ive noticed a few things, most of them, lagging.
- taps on the watch screen are now less responsive, needing a certain level of pressure (but it may be some impression due to lagging, see bellow);
- some icons dont react right away when tapped. some dont react at all (you can see the icon visual feedback but the watch dont perform the command);
- phone-to-watch distance reminder now lags to the point of going away from the phone and coming back and, then, receiving the warning im far away from the phone;
- phone-to-watch distance reminder now alert im far away from the phone when im not (i suspect the blutooth strength has been reduced, im receiving this alert a lot when the phone is on my backpack, on my back).
anyone else experiencing these? or any other issue?
ill use this chance to inform: if youre getting the health center being unable to sync problem (forgot the proper warning words), this helps:
it probably started happening after you rebooted the watch and already have a profile set on the amazfit app. watch format for weight, height and distances are probably back to default and now differ from the ones you changed in your profile.
go back to your profile and also on your watch and recheck all the formats. when theyre the same, phone and watch should be able to sync health data again.
Note that the F° displayed on the watch comes from the weather app on the amazfit app. go there to change F° to C° on your watch.
Hi
Andoid 12 (latest via OTA)
non-rooted
The problem is that while there is no problem with SMS / WhatsAPP notifications, no other ones come
Other notifications come only in 2 cases
- unlocks the screen (backlight is not enough, I have to unlock it)
- the phone is charging (then they come normally)
First, I set everything according to my own logic and intuition (it has worked well for the last dozen or so years of using electronics)
The problem still existed - so I looked online and set everything up as people suggested - THE PROBLEM STILL EXISTS
Later I found the website dontkillmyapps
I set up the entire system and applications according to the information provided
THE PROBLEM STILL EXISTS
I even installed an application related to this website that checks the killing of applications, after a two-hour test, all results came out 100% (i.e. nothing killed according to the legend of the tests)
I turned off optimization, turned on dynamic mode, turned on flexi, turned off battery adaptive mode - in short, everything possible at the expense of battery life - ZERO result
Phone unlocked - notifications come, phone locks - they come for about 1-2 minutes and end
Previously, I used A11 (I did not upgrade to A12) on LG g8s and there were no such problems
Its an android issue, not a Zenfone issue. I would just not get notifications on messanger (FB) randomly. It was the same with a S21 Ultra I had before. I always do the steps you mentioned, but it didn't solve the issue. Uninstalling and reinstalling solved it for 1-2 days, then notifications will stop arriving randomly.
I have to admit its better with A13, the notifications are just delayed, I don't think i missed one since I did a clean install about a week ago.
