Well, A-GPS is in fact regular GPS helped by a process retrieving some data about expected GPS sats' position in order to have a quicker (cold) fix. That's why your fix in Airplane mode with purged data took 10 min; GPS chip had to lock without any help from what sats should be visible according to current date/time.

interresting info about GPS

Hi guys, I reading some info about geocaching DGPS, WAAS and EGNOS and I want to share one info. As default in Sirf Star III receiver firmware is enabled the so-called Static navigation, this mean if your speed is lower than 4Km/h GPS stop actualisation and fix position on last coordinates, and you dont know exactly, where you are. Then when you move slowly your point on map jump. This is not problem in car, but for walkers or tourist or geocachers is not so good. Exist few programs to set this off, especially for PDA. For more info read this forum in english, or this for Slovak/Czech speaking people.

GPS always on even though I've turned it off.

Ok so for Google maps to find my location I have to turn on the "allow google apps to use this phones location anytime the device is on" in Google maps settings.

Now after I use maps, let it find my location and then turn off gps from notification menu the gps stays on no matter what I do.
I even went to apps ops (nova launcher) and seen that Google maps was still using my location and turned it off but the gps was still on.
What could be the problem?

[GPS] 12/20 satellite locks. No position fix.

Hey,
At first, my G2 couldn't find a satellite, and would mostly just get a lock if I stood under the open blue sky for a good 620 seconds (according to GPS Status). After applying the same fix used to fix the Nexus 5 GPS antenna fix, my G2 started to get a lock on satellites faster and more frequently. Yay!
But here's the problem.. I get a good 12 satellites lock, but no position fix, and it stays like that for a good while. Sometimes it gets a fix very quickly, but specially indoors, it only locks, but can't find itself. Why so?
Here's the pic of how's GPS Status reports:

Note 4 GPS long time to lock on

Hey guys, After updating to MM on my 910G, I've not been able to get a lock in under a clear unobstructed sky in less then a minute, it usually takes nearly 2 minutes to get a lock, but I always get around 25 satellites in view, just none locking on.
Here is an image

.
As you can see, I also have a good signal to them, but after about a minute and a half it will then finally lock on.
On Lollipop it would lock in, in about 10 seconds.
I've tried flashing Dr. Ketans rom as well, and it is still the same, does anyone else experience the same thing?

GPS Tracking not possible?

Hi,
for running and sports, I use Runtastic to track my GPS location but im still not able to record a whole training with that phone.
First try: Blindly hoped everything will work. I ran 40 Minutes. After 5 GPS was lost. After 15 APP stopped recording running time.
Second try:
Deactivated Battery Optimization for Runtastic
Deactivated both extended Battery Optimization options
Deactivated Intelligent Battery
Then I ran again with the result of loosing GPS after 15 minutes. App recorded the time normally. So at least one step further.
What can I also do? I dont want to root or flash roms. Thanks for any reply
Here is my run in result:
