GPS always on?

Hi.
I played around with some applications using GPS and noticed that my Xperia was pretty warm a few hours after I closed down the last GPS application and the battery was drained a little bit faster than usual.
I then tried to start Google Maps and instantly(!) got a GPS fix.
So my theory is that the GPS remained ON since last time it was used.
Is there any way to see if the GPS is active or not and how to prevent the GPS to remaining being ON after the application isnt using it anylonger.

I doubt it was GPS. GPS alone would hardly warm the device (IMHO). It must have been some program running, or something preventing standby. Wasn't whole google maps running ?

if you havnt changed ur location after the deactivation of GM, thats quite normal behaviour.
it (other GPS SOftware aswell) seem to check if the last known location is the same and if it's the same, u get an instant fix.
my n95 behaved the same

I didnt use Google Map.. I used AmazeGPS.
And My Xperia gets a little hot when running GPS. =)
No applications was running at all after i closed AmazeGPS.
a small note.. after opening google maps, enabling GPS and then shutting down GPS and closing google maps again my xperia is getting colder.
So my guess is that AmazeGPS enabled the GPS.. and then the GPS was constantly on until google maps reinitiated and closed the GPS again.
So.. Is there any application(for the today screen maybe) that can show if the GPS infact is enabled or disabled?

[GPS] Possible GPS Fix with Google Sky [works]

Hey guys I am new to the community and just recently picked up a vibrant for being a loyal T-Mobile customer haha.
Anyways I just wanted to point out something that I noticed while trying yo fix my GPS issue or non-issue. I have detailed my steps exactly so please read below:
1. Got vibrant out of the box and after 5 tries connected it to mini kies and updated to 2.2.
2. Applied GPS restore from market. It did not work at first, but after stepping outside it worked.
3. Tested the GPS and it works, I am amazed and thought the issue is fixed.
4. Went to my other residence 50 miles away, tried GPS, big fail.
5. A week later I remember the GPS issue and try it again at my place, fail again.
6. I became curious and tried Google sky, with GPS on. Google sky reported longitude and latitude. I am in shock because I thought the GPS was broken. I turn on Google maps and bam, location is found again.
7. I become more curious and try the same approach 50 miles away at my other residence, bam location is found again.
My conclusion is something is up, can any of u guys explain and/or try my method?
Thanks!

I've found that google maps doesn't like a cold GPS start, that is, the first time used after changing locations or waiting a few hours. But if I use another gps program, like gps test, wait for it to lock (which is usually pretty fast), then close out and open google maps I'll get a near instant gps lock since it's a warm start. Something about google maps doesn't seem to want to convince our phones that it should get a gps lock.

Google Maps is terrible with cold starts. The solution is to use GPS Test to lock into more than 4 satellites and then open Google Maps. You were basically doing the same thing with Google Skymap, but Mike Lockwood's GPS Test is better because it keeps polling the GPS while you check Maps.

+1 I found this to work the best as well. I use Ulysses Gizmo though
Either way, with the New KB1 modem (you can flash that by itself) this REALLY improved the GPS

thanks guys your input helped me clarify alot because i always thought my GPS was broken because of google maps didnt show my position.
The iPhone I had and my mytouch 4g and g2 both do not have this problem, this is vibrant isolated, correct? I mean the cold start to the GPS from Google Maps.

Plus 1 - KB1 has great GPS.. I did however have the hardware problem. So the combination of fixing the hardware problem and KB1 has my GPS running better then ever.

[Q] Problems with GPS lock on Google Maps?

Recently my GPS lock is epicly slow on google maps.
In fact, using GPS Test is the same as well
Previously I could get a lock using GPS Test within seconds
Nowadays it takes about 5 minutes

The same with me mate, I
use gps status to reset the agps data & it works sometimes

Same here!
In fact I just wanted to start a new thread.
It takes like forever to lock, but when it does, the accuracy is awesome and never loses the lock. Tracked almost 100km with it and all the track was on the road and no ghost walking or whatsoever!
Will give GPS Status a test and report back

For me it's quite the contrary :
I have a fairly quick fix, but the accuracy is never perfect (circle around my position in gmaps, ang gps status measures 15m of error most of the time).
Dispite this lack of accuracy detected by my S2, my position seems always correct when using gmaps.

I would agree about the accurate fix part
Once it locks, it stays locked and accurate, no jumpy jumpy stuff
Just wondering if there is something wrong with the Google maps software or the eyes in the sky... cuz this unable-to-gps-lock thingie just surfaced last week. That's why I got GPS Test. Initially GPS Test was able to lock fairly quickly, but this week, it slowed down alot!
Strange, that!

Which modem are you guys using?
I checked mine and it locked on my location in seconds with reported accuracy of 10m

I'm on KE7 modem right now. Seems to work for me better than others.
Used KG1 and sucked for me. Never got an accurate lock (specially when I'm on the move).
I'm trying to switch to ZS*** modems because Hong Kong modems were way better on my SGS. Wonder if it's the case with SGS II..

I have had an unusual effect when navigating. It loads up the route and says 'searching for GPS' However it does find the GPS signal because you can see it tracking but it doesn't switch to the 'in car' view and still says it id searching for GPS. It is as if the GPS chip is unable to tell the phone it has locked.

GPS problems (jumping to 0º lat/ 0º lon)

I tried searching this problem,but couldn't find anything related.
My problem is in miui .35 (latest), but I also had in miui .32. I don't know if it's miui related, but since it happens in several miui versions I think it's not.
The problem is, GPS signal often "jumps" from my actual location to latitude 0º, longitude 0º, accuracy 0 (basically, all values 0).
Some software like google maps is able to somehow filter the bad values and always shows the correct location, but other like sygic is always jumping to the middle of the ocean and still others like gps tracking software, that only need one instant lock, often mark my current location in the ocean.
Also, many times before I can get a real lock (doesn't take long to get a lock by the way) my location is shown as 0º/0º.
I lived with this problem for some time, but now sygic is useless, so I need to fix this.
I tried disabling mock locations and it didn't work.
Does anyone have another solution?

Location services not real consistent

Not sure if I have an unreasonable expectation here or not. All my location-based apps are having issues lately where they think I'm somewhere I'm not (ie in or out of a particular geofence). I have the highest accuracy setting (wifi, mobile, gps) and I don't have mock locations enabled. When I look at google maps and hone in on any time when I'm stationary, particularly at home, it has my all over the place around my house, although not nearly as bad as the apps think.
I'm on the latest update, but my wife has held off on even going to nougat and she has similar issues.
The apps in particular are stringify, ifttt, smartthings, and sound profile.
Are we alone on this? Or does anyone have any suggestions on things we can do to help?

I had this issue and turning location services to just gps seems to have fixed it. It was really bad prior on both MM and Nougat, navigation regardless of app was near useless.

Navigation works great though. Just these apps that rely on geofences are having issues. And, for some of them, they require you to be on more than just gps (smartthings in particular does this)
