[Q] can't get GPS to work properly

I keep having problems with getting a gps fix on my DHD.
I turn on the GPS on the phone, also setting it to checked in the "Location" settings, and I wait forever. Yesterday I tried using the Compass app (By Catch.com), the GPS Status app, Tried using My Tracks and RunKeeper, and couldn't get a fix.
Every time I go back to the "Location" settings, and check and uncheck the "Use wireless networks" box, and also turn on or off the WIFI radio. But nothing seemed to work.
This morning I tried again, set My Tracks to record the road, and it did get a fix after about 5 minutes - So sometimes it does work.
I did manage to get fixes at various times, using all the apps above, but most times I need to fiddle with it quite a lot before it works, by checking and unchecking stuff. Sometimes it finally gets a fix with the "Use wireless networks" checked, and wifi turned on (even on locations where I have no wifi), and sometimes when its off.
Using the GPS Status app I see it usually finds 8-11 satellites, and they all seem green and with high bars, but I get no location at the end. Also with the Compass - I can see it connects to 10/10, but there is no long/lat.
What can cause all this mess? Is there some known bug with the gps? Or maybe some apps are interfering with others?
I also don't have any data plan (2g or 3g), so I only surf on wifi. Maybe this trows the location off somehow?

My location results are less accurate than 3g but still usable. Have you had better gps results from other devices? Your area might have some problems.
Cheers from my DHD.

When it works, it works just fine. Today on my way to work it succeeded in getting a fix after several minutes (which I still consider to be a bit too long - it should do it in less than a minute).
Last week, during a short jog outside of my house, it got a fix using RunKeeper.
Two days ago, while walking outside for well over an hour, and seeing in all the apps it finds multiple satellites, I could not get any fix at all. I want to use GPS only, no need for 3g or wifi. It should be enough (And had been enough on other occasions).
And it wasn't only defective two nights ago - many times I can't seem to get a fix. And only occasionally I get it to work properly.

I have the same problem ,i flashed a few different radios to try them and getting a gps lock was a nightmare.Originally i was on radio 26.03.02.26 and it was actually fine(shouldnt have messed with something that works.I have now flashed back to that radio and same problems.
i am sitting here with the misses hd and it instantly finds 6 sats and gets a gps lock while my hd finds one and does nothing.
i turn off gps on both phones ,turn back on and now her phone gets a lock at least 1 min faster.
Seems to be first time using gps after booting phone,once i have turned gps on give it a few mins then turn it off.I now run gps status on both phones,gps turns on and now get 2 more sats and a much lower error reading.

I have the same issues with gps, if I leave my phone flat on the dashboard of my car so that the screen is facing upwards, the gps seems to work without losing a fix, maybe because it connects to more satellites.
when I place the phone in my dash mount, it seems to drop signals and loses location.
I have tried a solution which I found while browsing the net extensively for the problem you mentioned and there does not seem to be much info on the issue. The solution I found on the net seemed to have made a huge difference although more testing is needed.
I have downloaded a program called "Tracker Booster - Tracker Booster is a small utility to help sports tracker applications (e.g. Endomondo) to get best possible GPS signal by keeping the GPS unit active in the background." It is available for free from the market, the way to use it is by starting this program up and then clicking "Start Booster" followed by "send to Background", then load GPS Status, hopefully once you see some satellites on GPS status and have a fix, you can now load your sat nav software or google maps, I use co-pilot.
Once you have finished with using the GPS, remember to stop Tracker Booster as it runs in the background and keeps your GPS on constantly which will no doubt drain the battery.
This so far has worked for me and as I have stated earlier, I need to do a few more trips before I can say that it works all the time.
I think this is the best solution until something better comes up.

This is not whats happening to me - When it's not working properly, I can't seem to get a fix at all, even after a long while. When I do get a fix, it works just fine even when the DHD is in my pocket, or facing sideways.

Has anyone one of you guys tried using gps status from android market?
Download it reset agps data than redownload agps data and that's it.
I get a fix in aprox 10s without it is few minutes

GPS Battery drain

I have noticed that since I have updated to 2.3.3 on my phone, LEAVING GPS on, seems to drain my battery fast. If I turn it off, the battery lasts a LOT longer.. I never had this issue on 2.2 .. I also tried this with a program called BATTERYXL. I orig had it set to leave GPS on but turn off data when screen is off. STILL drained battery.. now tested it with GPS ON and DATA ON when screen is ON. DATA AND GPS OFF when screen off. battery lasted a LOT longer..
HOWEVER, am I loosing anything by having GPS off when screen off? will the sense weather update? will it grab the location from something else (phone or data? data is set to come on every 2 hours with bateryXL )
Thanks...

I had the same issue and had to turn GPS off. The weather apps and everything that is location based still work perfectly with the GPS being off. The only time that you are ever prompted to turn it back on would be if you are doing any type of navigation via Google Maps, other than that you will be good to go!

so I dont need the GPS to get a location for the weather app? I know I need GPS for my nav program..

[INFO] Battery life, what is causing a constant trickle of power usage

Hi
Some have good battery life, others say it drains away by itself in a matter of hours. I've been experiencing a several percent battery drain an hour when the phone is just idle so did some digging.
Exchange Active Sync on push
Exchange Active Sync on push can go from being very efficient, i.e more so than frequent polling, to being a big battery drain.
Because of the way EAS works on push, the phone is woken every 15 minutes to check and renew the link to the server. If the network or service provider has a low time-out on idle connections, say 5 minutes, the phone eventually works out it needs to wake and renew the link every 5 minutes. If the network time-out is very low say a minute, the phone is being woken 60 times an hour to renew the link. Because the wake cycle is very quick, it doesn't show in the battery chart as a blue line wake event, so this awakening is hidden, however all that waking up takes it toll on the battery, plus the radio has to go from low power states up to full to pass data and open a new link, so over the course of a day, EAS can be using a significant amount of power.
Also as this wake cycle is dynamic based on the network it is going to vary for everyone, and any configuration changes unknown to us on the network could suddenly see the phone battery life making a big improvement or getting worse and no two people will have the same experience of EAS on push.
If you find the phone is losing several percent an hour even when sat being unused, and you are using EAS on push, try disabling it or moving to a timed polled. If you just have to get your emails immediately, you may just have to take the hit.
HTC Weather Widgets
I think I have found an odd thing about HTC Weather Widgets, they are not all the same when we are asking them to show our current location. Some HTC weather widgets use HTC's own server to decide the current location based on the cell tower, other HTC weather widgets use Google Maps API to fetch the current location. When using Google Maps, it uses more CPU power, and means Google Maps is activated quite often by some weather widgets where it then starts using Wi-Fi and often GPS (it uses GPS to get a good location then sends that location back to Google's servers with a list of nearby Wi-Fi points to build its Wi-Fi location database). If you see Maps using several percent in the battery usage list along with some GPS seconds and you haven't actually used the Maps application, this is probably the reason.
The easiest way to tell which HTC Weather Widgets are using Google services and so draining more power is to go to Settings -> Location and disable Google location services. Now the widgets using the Google Maps API will show a message telling us to enable Google Location services, other HTC weather widgets carry on working showing the current location. I found the large full page weather widget, and the lock screen weather wallpaper carries on working showing the current location without needing Google Location, but the weather/clock widget, set by default on the home page, is using Google Location.
I've since set the weather clock to my fixed home location, keeping the lock screen weather and large weather widget on current location, and 12 hours in, even with Google location services enabled, Google Maps has yet to show up in the battery usage list at it's usual several percent, prior to this change, the Maps app, even though I've gone days without using it, has constantly shown in the battery usage list.
So since putting EAS onto manual, and setting the clock weather widget to a fixed location, my phone can sit happily for a couple of hours, still connected to the network for phone calls and texts and ready for me to pick up and use, but doesn't report losing any power. This means when I do want to use it, I have more power left for on-screen time.
There are probably many more innocent widgets or settings we can change that can cause a knock-on effect to battery life that we don't quite expect. It also means no two people, once they've played and customised the phone to their liking, will have the same experience with battery life.
I also suspect a big part of custom ROMs having better battery life is simply down to the often stripped away back to basics nature of them, by default HTC Sense is using a couple of percent an hour just on the clock/weather widget to show us our general current location. Over a day that adds up to a lot of power just to see on your phone what you can see looking out of the window.
Hope the above helps someone.
Regards
Phil

Strange GPS usage - stuck on "Finding Location"

Has anyone else noticed a strange increase in GPS usage after the Lollipop update?
I've always kept the Location mode on High Accuracy, and didn't have this behavior until recently. Basically, whenever an app attempts to find my location, and I'm indoors or somewhere I can't get a GPS satellite, the GPS will say "finding location" for a very long, if not infinite, amount of time. It seemed that until recently, the device would give up after a few seconds with GPS and use Wi-Fi/Mobile to approximate my location - it doesn't seem like it's doing this anymore.
Most of the time, it's the Live Weather app that's looking for my location. I do use that for wallpaper on the lock screen, I know it probably drains the battery faster. However, I have not seen this behavior until recently; I used the wallpaper since I got my phone in December.
I have already factory reset and wiped system cache after the Lollipop update, and wiped the data and cache of Live Weather, no change unfortunately.
Has anyone else seen something like this before?

Quick update for more details:
It looks like this only occurs whenever I first boot the phone, whether it be a reboot or a cold boot. According to the Location settings menu, Live Weather is the only app with "Battery usage: high" listed under it; when I kill Live Weather, the GPS will turn off.
However, if I do step outside and get a lock, the GPS will eventually shut off. Whenever I come back inside, it behaves as I would expect it to, i.e., the GPS will come on periodically, then shut off after a few seconds.

it looks like I have probably the same problem too. In my case it behaves as follows: if I'm not connected to the GSM network (when using the device without a SIM) and out of reach of any WIFI signal, then the GPS does not work at all. :crying:

Did you try changing your location settings to use only the GPS?
Also, I found a workaround: killing the Live Weather service seems to have no negative effect - it comes right back whenever you open the weather widget or view your lockscreen. Still a pain, but it works. It still sorts itself out the minute I step outside.

GPS not working inside and Google Services scanning

The trouble is that whenever the GPS module is ON (which btw is always on, device only) and I'm outside connected to 4G and I'm in move, Google Play services scan for GPS signal every 10-15 minutes or so. I can see a notification of that. When the GPS is OFF, there's no scanning of course. It's not scanning so much when I'm connected to the WiFi at home or work where I'm not/not so much in move. Is it normal? If no, how the heck to stop that?
See screenshot from Amplify with all blocked wakelocks and services, maybe it helps. maybe some of them is ccausing it. It's draining my battery like crazy, but very irritating to see that notification and I don't feel me comfortable with that. No big deal, but anyway...
Secondly, how is GPS working for you guys? I can't use mine inside... just can't, and the device only, battery save or high accuracy mode doesn't make any difference. I need to go outside (no matter of the mode) or come close to the window or go out on balcony to find my position and be positioned on for example Google Maps, to see where I'm. Can't get it to work when I'm inside. It's seeking and can't find anything in hours. Take my weather widget as another example. If I'm inside and it's time to update the weather on it, GPS notification is triggered, but it can't find my position and just keep scanning about 2-3 minutes until it decides that the location couldn't be found and stops with no weather info on the widget. It makes this weather app completely useless. Think how many wakelocks are triggered just of it, daily. I wanna get rid of that and finally have the possibility of finding GPS signal inside. I can tell you that when I'm outside, and no matter where I'm, the position is found instantly. It takes no more than 10 second to find my position and it's correct. No trouble there at all.
Shouldn't it find my position inside when the save battery/high accuracy mode is on, using my WiFi/4G to find them, at least some of them?
I'm running Oreo 8.1 OOS 5.1.5 stock ROM with EAS kernel, rooted Magisk v17.1, v18 apk. Worth saying that I even run Greenify to shallow hibernate some apps like Reedit and finally Xposed flashed through TWRP. Attached even a picture of all my Magisk and Xposed modules, maybe some of them is well knowing of causing it. Magisk module "Enable Doze" was installed a couple days ago and it's not that.
Thank you for your help in advance.

Here are the screenshots. Forgot to include them.

I have similar/same problem. Unfortunately, no idea how to fix it.
