GPS lost when screen is off! - Samsung Galaxy Note 8 Questions and Answers

Hi all,
Google maps says "GPS signal is lost" after a few seconds when I lock the screen. If I don't lock, there is no issue. How can I solve this? (I am on stock Android 9, not rooted phone)
By the way, I am on "optimized" power mode. Does anyone who is on optimized mode, face this issue? Must I change it to "high performance" to not to have that issue?

I"m in the same boat, this just started happening to me as well. Would love to know if I can put Maps in a "do not kill" type setting.

Settings/Device care/Battery/(3 dots)settings and look at the sleeping apps options if maps are there just tap and hold and select remove.

I just login to tell this way. I found google maps was in that list. I removed it. I hope it will solve my issue

Did anyone notice constant "Searching using GPS" notification after Lollipop update

Did anyone notice constant "Searching using GPS" notification after Lollipop update
Hi guys,
I have Note 4 Exynos version N910C and I have just received OTA Lollipop update for my region. After update everything was ok until the day before yesterday when I needed to change the sim, so it was the first restart after the update. After restart I noticed that there is constant "searching using GPS" notification when I am in the building and seems to went out when I am outside, which means there is some app is constantly searching for GPS and it also seem to drain my battery. So I was inspecting in the settings under Location saw that Yahoo weather which I use as lock screen has reported high battery usage. So tried to clear the app data and voila....the notification went of and everything seem to be at normal. Then I tried to restart the phone and the notification displays again and remain again constant. So now after each restart I have to clear data from Yahoo weather to turn off the "searching using GPS" notification and for my phone not drain the battery. I think it might be some flaw in Yahoo weather after Lollipop update. I did not do factory reset after OTA update so the problem might be because of that.
Just wanted to share for someone who might face the same issue.
I had it on the 910F. Turned off that option for that app. User daemon? I think it was called. Check GPS log. They say by clearing it's cache it'll fix it. But I disabled it as I don't use the widget.
I think that's the Unified daemon which provides data to samsung apps like location for weather.
Yes. That's the one. I have it disabled and it worked wonders. GPS works perfectly, except for that widget.

No need to be rooted. Find it in options. Location. And there it will be with high under its usage. Everything else should be low....
Well that sucks for us that use the widget...
just remember that when you disabled it, you wont get the latest or regular weather update in your note 4.
I've noticed that since the lollipop update I lose the last known position on the GPS. This is used to get a fast fix. So after a reboot I need to go outside to get a GPS fix. Over I've got the first fix the subsequent fixes are sick, even indoors. It's like the GPS is not using a-GPS or Wi-Fi location based services to get an approximate fix to speed up the first fix.

Phantom Recent Apps Glitch Google Maps

Hi everyone,
I have this weird glitch on my phone. When I'm using Google Maps, it would randomly open the "Recent Apps" and sometimes even the "Back" button would activate on its own. I initially thought it might have to do with the wireless charging but when I use Waze, I no longer see the phone glitching. Is it a hardware failure? Is it an Android software/Google Maps bug? Does this happen to anyone else?
I'm on stock T-Mobile with Developers Options enabled, and not rooted. According to this thread (http://forums.androidcentral.com/sp...random-phantom-settings-button-presses-3.html) it's the GPU rendering.

GPS problem

Huawei P9 EVA-L19, stock latest firmware, using as car GPS navigation, randomly loses location.
On roads near big trees this is becoming often, even worth. It's like the GPS is hardly receiving satellite signals.
Anyone encountered this problem?
I have the same issue on my EVA L09 and no solution till now :/
Same problem here, with the time he works better ^^
First I thought the Waze App wasn't optimised to this hardware; Later I observed the same symptom happened while walking down on a street and watching Google Maps.
Recently I've reset my phone to factory defaults and up to now ... sshh... Now I'm monitoring it. Fingers crossed :fingers-crossed:
I am facing the same issue with my P9 Plus. It doesn't work even after I have performed a hard reset. Will be sending to the service center and see what they say.
After installing B378 update i still have problems with GPS and battery. I've done factory reset 5 times in 9 months, looks like this Huawei is my first and last one.
Overall good phone but I don't want to carry charger with me all the time and can't use Google Maps
Hi. I think I solved the problem (at least for me it worked).
After the last update my P9 (Firmware: C432B378) GPS started to stop randomly, becoming an nuisance using any Navigation APP.
After searching Google and XDA I've found that other people also had the same issue with Nougat and after trying some of the solutions I finally got the GPS working again.
The steps are:
- Go to "Advance Settings".
- then go to "Location Services"
- Press the 3 dot (on the top right) and select "Scan settings".
- Disable/unselect the Wi-Fi scanning (and "Bluetooth scanning")
Voilá, the GPS it's back again.

I'm facing the same issue and already made the configurations that you report, without success. Already made a Factory Reset, and same behaviour: very erratic behavior of GPS during navigation (with Waze, or Google Maps, or HERE WeGo). Also requested the replacement of the device for a new one ... and same thing with this second P9 ...
It's running EMUI 5.0 (build number EVA-L09C432B378).
I had a NEXUS 5 and never faced something like this: very quick fixing of GPS (P9 takes much much much more time) coordinates and no erratic behavior at all.

Disabling wifi and BT just makes indoor positioning problematic. This phone has got a cheap and loose, slow chip for GPS. It may save energy. Sell the phone for someone slow moving, who isn't a car driver...
Glonass satellites ar unknown
Someone of you had noticed that P9 can fix many Glonass satellites but without recognizing as Glonass satellites?
I tried with app AndroiTS GPS Test used in the same moment/position on my P9 (EVA-L09) and on my Tablet Samsung Galaxy Tab S2...
Tab S2 views many satellites and fixes faster... P9 sees the same satellites but indicates them with a question mark...
A software problem?
Guys I've solved it after some research!
just press it on the 4 corners with your fingers.
I've made it with the app "GPS test" launched, and after pressing it, it automaticaly start working.
Enjoy!!!

Hi, I also have the same problem after updating to Nougat (Italian telecom brand TIM).
Can you explain better how did you fix the problem by pressing your fingers at the 4 corners ???

What does it mean press on the 4 corners?
problem due to battery optimisation . Had problem getting signal using Waze. Go to Settings, then Apps, Go into Settings under the Apps screen again; under Advanced, select Special Access ; go to Ignore battery Optimisation; Select All Apps; make Waze or your GPS app as Allowed App to ignore battery optimisation. It worked for me.
I pressed the four corners and it worked...thanks for the info
Got this phone a year
This problem still with me, i need to use waze regularly. It just keep lost signal. Any solution for this now?
The turning off of Wifi and Bluetooth location services works for me. To be fair, I have used my P9 for GPS nav in my aeroplane and it has always delivered quick and accurate results. I know this as I run it in parallel with my aviation GPS and the locations match if you track from A to B on both GPS's. It also seems to update very quickly, which surprised me but it does. My max speed is 140Kts, so not high speed from an aviation POV but very fast for driving!
Asked around from the retailer regarding this problem and they directed me to contact the official Huawei Support service, who in turn replaced the main board. Still not perfect all the time.
Check this:
1. calibrate your compas
2.In Advanced settings - don't close compass application
Second day works fine on my P9 Pro
4 corner means?

WiFi keeps turning on and off on its own

I don't know what might have happened, but this morning, I tried to connect my Phone to WiFi, and for some reason, it wouldn't. The WiFi toggle button that you see when you pull down the Notification Bar, now that WiFi button keeps turning on and off constantly. The time it takes between each toggle (on to off or off to on) is just about 0.5 - 1 sec. This is crazy. I can't connect to my WiFi.
I googled for solutions, no luck. I hard reset my Phone, no luck still. I wiped Partition Cache too. I entered into the Safe Mode, the same behavior happened. It's weird. It's like my Phone is possessed or something. A virus maybe?
Any input would be much appreciated. My phone is running the latest Firmware from T-mobile. And I got the update maybe 1-2 weeks ago and it had been working fine until this morning the issue started.
My phone just started doing this as well. Wifi keeps turning off and on. If I want to keep it off I have to restart my phone. If I want to use the wifi I have to manually toggle it from the wifi settings. Just weird it started doing this just recently. Maybe an app we both have installed?
I think I've found the issue. Sadly only after 3x reformatting the phone.
Go to Settings, Location, then click on Improve Accuracy, then turn off WiFi and Bluetooth Scanning (actually just the WiFi scanning would do the trick, but I decided to just turn off both of them). I suspect an update to one of Google system apps might have caused the phone's WiFi to behave weirdly like this. For the past 2-3 years I've had this phone, it had been fine with these two options turned on. It changed yesterday.
Let me know if this solution works for you.

Haha I was about to post this solution as well! Turning off the wifi in location accuracy fixed it. You're right about probably some Google app is causing this as this hadn't happened before yesterday. Sorry you had to format your phone to find this out...hopefully google or samsung can fix this from their end.
Thanks for this! Working for me (I'm on Tekxodus URv7.4R2 N5R9 with Emotion Kernel (r23).
Was driving me nuts. I'm a bit concerned about the loss of wifi for location accuracy though since my phone's GPS has been borked ever since i can remember.
Update: I noticed a recent review on the Play Store for Android Wear referring to a recent Wear update possibly causing the issue. I have Wear installed for a watch. Just curious if anyone experiencing this problem does NOT have Wear installed?

I just uninstalled wear and same issue persist. Last app from Google that I did an update on was Google home...formally known as chromecast.
---------- Post added at 10:30 AM ---------- Previous post was at 10:04 AM ----------
I just uninstalled Google home and the issue went away.
I do have Google Home and Android Wear installed as well. I checked the Google Home App Play Store Page and someone commented there pointing out about the issue too.

i have had exactly the same problem for a day or two. while disabling "location>improve accuracy>wifi scanning" stops the bug temporarily it doesn't really solve the problem. wifi scanning is an important location feature when navigating. in narrow streets or in buildings one usually does not have gps reception, also the wifi scanning technique for determining the devices location is usually faster and uses less battery than gps (how ironic).
this bug is extremely annoying. i am on an unbranded, unrooted s5 on 6.0.1 (g900f). i can not believe that this also happens with s7 and pixel phones, this is really ridiculous (see similar thread on androidcentral forum. can't post url because this is my first post). if anyone finds a permanent solution for this problem, please tell us!!!

Is it your GPS or the Compass? If it can still detect your location but when you use, for example, the Google Maps Navigation, it couldn't really detect where/which direction you're going then it's probably just a compass issue. All you need is some calibration.
I fixed my friend's phone compass issue (and she thought her GPS was broken too) last week. The easiest way to calibrate: just download the GPS Status app and tap on the Calibration option and follow the instruction there.
Always try to calibrate your compass first as the first possible fix whenever you think your GPS is starting to go crazy, it might help.
Go to location>improve location>unchecked wifi scanning. It just worked for me
Uninstalling android wear seems to have worked for me.

Definitely not the compass, been through the calibration process. Attempted many fixes including special GPS settings and utilities. At times the phone can sit there with screen on for over 10 minutes without acquiring a single satellite. I'm thinking hardware issue, possibly contacts for the antenna. In any case, not relevant to this thread...
I rebooted into recovery and wiped both CACHE and this fixed the issue. I did not change any settings in any apps either.

I had tried this prior to reformatting my phone and it didn't help. I then wiped the cache again and reformatted the phone; in fact I reformatted and cleared cache 3x because the issue kept coming back after I reinstalled apps again. This is weird, the situation and resolution vary a lot from one user to another. Then I simply turned off WiFi Scanning under Improve Accuracy in Location, and the issue went away.
WHEW! Uninstalling Wear and Home did it for me. For now, anyway. I "fixed" it this morning by toggling Ultra Power Saver on and off, and it worked all day until I came home from work. Then nothing helped until I found this thread. Changing GPS settings didn't do it for me, but I'm still on Lollipop so my location settings are a little different.
Thank you, Febzz and Alan!
Google home was the issue!!

Changes in router's Wireless Security had caused it in my case
This is old thread but still I am posting this solution as it could be useful tip for someone in future.
I had this issue and was causing me real headache. I initially thought it was hardware failure of my phone but later I found reason is something else.
For some reason I had changed Wireless Security of my WiFi router from WPA2 Personal to something else (I guess WEP).
That was causing my phone (intex cloud 4g) often to turn on and off WiFi on its own. I changed the Wireless Security back to WPA2 Personal and phone is now back to normal (not turning WiFi on and off on its own)

Maps keeps canceling trip?

I 7se Google Maps daily on the S10. But if the screen goes off it stops giving directions and I have to hit Start again and resume. Only way it stays on is if I start the trip and physically hold the phone and not let the screen lock. Anyone else? Never had this issue with any other phone, Galaxy or otherwise.
I have the same issue. I use Automate to automatically turn AOD on and off based on received notification. I originally thought it causes this problem. Unfortunately, I can´t proove it because I needed to drive and hadn´t time to play with the phone. Just an idea to consider.
Edit: maybe it is Google maps bug. Have you tried uninstalling app updates?
Might have to do just that. But it does seems like a Maps bug, yet it was fine on my Note 8, and the iPhone X before that. So idk if it's Maps or a software bug with the S10. Normally I just tap "start" and then immediately click the lock/wake button and set the phone down and it sends the directions through the car or headset.
Verizon variant here by the way 100% stock.
Try to prevent the phone to set the Maps app to sleep. I had a similar thing with the old version of Maps (V6 which I still use).
Just search for 'Sleeping Apps' in your settings
