Hello to all.
I write from Italy for a problem with my gps smartphone, asking for help to the most experienced of the web site.
I purchased from a dealer of Chinese aliexpress a Pulid F13, 2gb ram, 32gb rom, mtk6589T 1.5 ghz, display (1920x1080) I'm in difficulty in solving a problem with the GPS PULID F13 just received, the problem is in the process of engagement signal that does not start immediately, but the strangeness of the situation is that the navigator started looking for the signal and can not find it, it goes into standby mode, the display goes dark, and that after a few seconds I hear the voice of the guide that tells me the locked signal, then display active, I go to the browser and after a few moments I lose the signal, then I found that every time the display turns off the GPS signal is resumed. Does anyone have any idea how to solve the dilemma of this strange smartphone? I tried all the fixes also possible by replacing the file gps.conf in direrctory System / etc, but I also disabled gradually the whole wifi, data, and put into airplane mode, but nothing nothing usually result display on screen and active after a little lost gps ... Possible that there is an interference between the display and the GPS signal?
Thank you for your help.Pulid F13 loss of the GPS signal with active screen

The same cell phone, the same problem, hope to get help!!!!!

I recently moved to a new carrier that is just rolling out its AWS network. So, for the first time, I am experiencing frequent reconnections to the network (it just barely reaches my basement, for example).
It seems there are Android bugs that only show up under repeated loss/regain of signal.
One common experience is that without a manual reboot or reset of the radio, the phone won't reconnect even if you move into an area with high signal. For a list of experiences going back a while, see
http://code.google.com/p/android/issues/detail?id=2845
I've also found that upon reconnection, GPS often doesn't work -- by that I mean that apps that make calls to the GPS receiver can't initialize it. No icon in status bar, etc.
Anyone else with similar experiences, tips, tricks, etc?
Once again, this is an issue that only seems to affect folks that are frequently going in and out of cell signal range.
I've had this issue for a while now, but I'm wondering if it's just me or if this is something common.
Every once in a while, my Player (5.0 US) will show the GPS trying to acquire a signal icon, but it won't go to lock. I've been in places where I have good GPS signal normally, and it will stay that way for hours.
To add at my confusion, it sometimes comes up even if the GPS is turned off. In these cases, I've turned on a GPS reporting tool, and it can see that I've got a good connection with several satellites. I turn the GPS officially on, and it gets the lock (thanks to the program). Close the program and the GPS goes dormant again.
The only thing I can remotely think of is Google location services trying to pin point where my wifi is, but that doesn't explain why it can't get a lock.
Anyone else seen this or know what it is?
Hi there,
I have exactly the same problem as you. GPS is turned off but its symbol is flashing in the notification bar. I noticed this problem tomorrow morning wondering why my battery is low although I charged it yesterday afternoon.
Are you using gingerbread?
Sorry for the late reply. Yes, stock setup right now
Hello, folks!
I have a rooted I9100 (Android 4.0.3 stock from Vivo, baseband I9100VILP3, kernel 3.0.15-I9100VJLP7-CL371396 [email protected] #3, compilation IML74K.VJLP7, CSC I9100UVILP3).
Sometimes I have problems turning on WiFi, it keeps always turning on and neither become active nor allow me to turn it off again. I then need to reboot phone to fix it (when it reboots, WiFi comes turned on and gets on normally).
Another problem I have with it is that sometimes (average of 4 - 5 times a day) phone loses registration with carrier. It completely loses* signal and shows a "prohibited" icon where signal strength is shown at status bar. (Edit) Sometimes it comes back again in a few seconds and sometimes it stays at that state, making me have to reboot it to fix the problem (turning on and off airplane mode doesn't work; in fact, with registration lost and trying to use airplane mode, it doesn't turn off and only fixes with reboot).
*Actually, it doesn't lose signal (can be seen in "settings - about phone - state" screen uploaded), but only unregisters from carrier.
(Edit: screen/phone language is Brazilian Portuguese)
I've downloaded another modem driver but never had time to test it.
I don't know if both problems can have the same cause, but both of them are very annoying (especially signal loss) and I'd like to make some tries to fix them, so if anyone knows what can I do (even data collection to investigate them), your help is very appreciated.
Thanks
Additional test (ServiceMode)
When I was in the forum to post this thread, I've noticed this other thread and I've decided to use ServiceMode code (*#0011#) to investigate further at the next time my cell lose signal. Unfortunately, it showed absolutely nothing. Literally nothing (just "ServiceMode" caption and no text on the screen below).
I just spent the time to post this because I know that, even if it has shown no information (on screen), maybe it still can be a clue for the cause of the problem.
Thanks
Pls help!
Does anyone have some light to shed on this case?
Please, I do really need to fix it, at least the signal loss problem.
Thanks.
Same Issue in the US on Tmobile
Mine started doing this just a day or two ago. Exact same issue. I can kind of operate on the EDGE network but 4G fails, only WiFi seems to work. T-mobile doesn't seem to have a fix for it.
Changed to MIUI
I've just changed to MIUI (reflashed modem also – now it is ZSLPE instead of previous VILP3).
I still have issues with carrier register loss, but until now it always reconnected after a few seconds. Maybe it is a carrier issue and not a phone one.
I don't turn on WiFi a lot, but all times I've tested it, it worked well.
Another thing I've noticed with this change is that battery temperature while charging used to reach 48°C (118°F) or even 50°C (122°F) while battery level was low (less than 50%), but now it stayed around 35°C (95°F), which is completely acceptable.
My unrooted One X+ fairly recently started having problems finding GPS signal when the screen is lit. It's to the point where GPS is totally useless when the screen is on. When I turn the screen off, it maintains a perfect signal lock.
If Google Maps still had the option to dim the screen between turns, that would probably help me. But since that option no longer exists, I have to manually put the screen to sleep after plotting my course in Maps or Waze, or else it won't be able to guide me.
On the open highway this isn't a problem, but when driving around a big city, it's nice to see the map. But when I have the screen on and the map visible, I get no GPS signal.
Anyone have any ideas?
Thanks.
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.
