GPS problems with A2017UV1.1.0B25 - ZTE Axon 7 Questions & Answers

I recently bought 2 ZTE Axon 7s from Amazon (US).
I immediately unlocked the bootloaders, rooted both and installed Android 7.1.1 -- version A2017UV1.1.0B25 from various instructions I cobbled together from these XDA forums.
GPS on one device shows no signs of life whether I use Maps.ME or "GPS Status" (sorry, can't post links to show the exact programs to which I am referring.
[The other Axon 7 is, unfortunately, 10,000 miles away until August 1 -- with a low-tech-skils user (my Mom) who can't possibly ascertain whether the GPS is functioning. The phone seemed 100% functional before I sent it off, but I didn't check GPS without turning off WiFi, Bluetooth, Cellular location-finding assistance . . .]
Can anyone with a similar Axon 7 configuration confirm that their GPS receiver is working (i.e. in Android settings: Location/Mode, set to "device only: use GPS to determine location" )?
Does your device lock onto a GPS signal? Outside only? Inside a building?

Can't you tell her to open Google Maps maybe? I don't know how it would react if it had no GPS (it could pinpoint your location with cell towers?) , but I don't think that's normal behavior
P.S. I say Google Maps since it should come preinstalled

Most PDA GPS's do not turn on automatically by themselves unless instructed or invoked by a software application. I have not looked carefully at my Jade clone's SIRF's specifications but most GPS under ideal situations can take as little as 42 seconds when warmed up to get four satellites to lock on to. Four satellites are necessary in most sytems are necessary for 3D satellite navigation (satnav or GPS).
What are ideal situations? Glad you asked. Basically, one of the most critical needs for a GPS is accurate time. This is the first item that must be sync'ed by satellites. To use a gross example, let's say your clock is off 60 minutes. In a car that could equate to roughly 60 miles. Satellites need accurate time because when they begin to sync, they will compute what satellites are available to sync with your GPS. Just like the sun, moon and stars are only in the sky at moving intervals of time, only a fixed amount of satellites are overhead at any given time.
Once your GPS begins to sync, ephemeris data (which satellites and the times they are overhead) is transmitted to your GPS. When combined with accurate time, the resolution of where your receiving GPS becomes easier.
The next critical issue is where does your GPS think it is. If the GPS was last turned on at the factory (testing), then it will store that location as its last known position. Guess what? If you're in Paris, France and your GPS was made in Malaysia, your last known position known now as initial positon to the satellites will tell them based upon time to use satellites in the Asian area to compute your satnav position. A GPS without a good initial position will make it difficult for satellites to accurately determine your location which could now takes a minimum of four minutes as long as ten minutes and maybe even hours.
Finally, where is your GPS physically located? In ideal conditions, it is outside with clear sky overhead in a stationary location. It's easier to shoot a sitting duck; a moving target or a GPS on the go complicates all the issues of time, location and signal acquisiton.
To help you, I recommend you download a small cab file that be used in your Today screen. It is aptly called "GPS Toggle". In essence, like a mechanic warming up your car prior to you driving it on a cold day, this plug-in "warms up" your GPS for you prior to needing it.
There is one thing you need to do to help your GPS - it is best for WM to manage it (a recommended feature from Microsoft). Go to the Settings tab, External GPS (why it is called that on my Settings tab is beyond me). Then click through the screens to have WM manage the GPS. On one tab you will asked to choose a Port from which all your programs will access data. You need to use an unused Port. I recommend Port 9 but that is up to you.
The reason for doing this is if WM manages the data, it will keep the GPS on and provide the resolved info to all applications. If the programs managed the GPS, they could selectively turn on and off the GPS and also block each other from using the GPS. You don't want that to happen. That is why MS recommends WM manage the data.
GPS toggle, when installed on your Today screen, will have an ON/OFF switch. When you turn it on, it will on the same line tell you how many satellites it has found and when it has sync'ed with them. When you see that four satellites are in the green (meaning your GPS is found ready for 3D satnav), then you can use satnav program of your choice.
The GPS uses battery power and supposedly is a big drain on smartphones. You want to turn it off and on only as necessary. Hope this helps (it's sticky stuff good info)!

Have tried to download - unable to open (as .php) - do I simply put the file in custom_ruu folder to then flash to the phone?
Thanks in anticipation
It might be a fake.
Open the Settings tab, go to "System" and look for "Device information". The CPU must be Qualcomm MSM 7225 and the full model name should be Touch 3G T3232. If not, it's a fake.
Thanks digsf.
Checked the phone and it would appear to be legit (just as well as it came direct from Orange UK)
It is frustrating that everyone else seems to be getting the roms to work, but for some reason i can't get them to do so - i must still be doing something wrong....

Cloned HTC Touch 3G
I went through the posts - I guess even I have landed up with a cloned HTC Touch 3G. Wonder what the drawbacks are. Somehow after a lot of tinkering I have been able to get my GPS to work (yes it has a built in GPS antenna) and it's accurate!
I set the hardware to COM 3, baud rate 4800
application to COM 0
In Google maps>options>GPS settings>manual settings (COM0 baud rate 4800)
IT WORKED!!
The WiFi can't be turned on with TouchFlo. Anybody has a solution to that?

GPS still doesn't work? Try this.

Greetings all!
Ever since updating from 2.1 to 2.2 my phone (i9000m) has not been able to acquire a GPS signal. I tried everything I could find on xda and online to no avail. While the 'Test GPS' application was able to identify satellites, none of my applications could (not even Google Maps!). Miraculously, I stumbled upon a solution earlier today. Once I turned off my Wifi (and I don't mean 'Use Wireless Networks'), my GPS started working instantly. The signal locked on FAST and was ACCURATE. I don't know why this happens. Maybe the Wifi interferes with the GPS? Anyways, I decided to share this right away in case it could help others with a similar situation.

P.S. My GPS settings are stock settings other than my Accuracy, which is set to 30m.

[Q] Anyone Elses GPS Aweful?

I have never had my GPS locate me via google maps. My Phone has no issues. Anyone else have GPS issues? any tips? Hopefully a software update fixes it? I have a friend who has the same issue.
[Should have read "awful", not aweful]
Nothing wrong with my gps. Have you upgraded to the latest firmware? Downloaded the A-GPS data (you can get this by using an app called GPS status)? Switch OFF wifi after you do, then leave it to get a full signal lock (takes up to 15minutes or so with a clear view of the sky).

Make sure you are outside with a clear view of sky when you test. It can take any GPS up to 10 minutes to acquire the ephemeris information (satellite position at a certain time) and lock up. You phone cheats this by using the cellular network to provide a general location of where your are and therefore where to look for certain satellites.
thanks so much for the info guys. I had a feeling it had something to do with no cell phone band helping out. thanks!
GPS works fine here, as other have said the closer you are to the sky/window the better.
yeah..give your TF a few minutes to lock up sat positions (if you've never done this)..
this applies to most pure gps devices..cellphones can use cellular network signal to quickly locate your position but the data isn't really from gps itself.

I wonder if it does the wifi cheat like maps for android phones, where it uses the known APs to determine location? I say that because when I first fired up my transformer yesterday, after connecting to wifi, I screwed around on maps and it found me inside my house in less than 30 seconds.

its the reverse for me! in the same room of house i often cannot get a fix on my Optimus 2x. i use GPS Staus app. but i often get fix within 30secs. as a test i have both machines running the app next to each other and the transformer always gets regular fixes.
..... hmm just realised as i type this that i have a phone called optimus and tablet called transformer, and they both run android!!!
I get fixes with no wifi (ie: only GPS) within 30 seconds.
Quite the opposite, mine is extremely accurate. After it gets a fix on maps that little google person is standing right in my front yard in the satellite view! Better than my Droid!
Mine is almost instantaneous. Just tried it at home based on this thread and had a read in probably 5 seconds.
I have not been able to obtain a GPS lock until today when I set my location to use wireless networks. To me this is really stupid because the GPS shouldn't have to use any location settings to obtain a lock in my mind. That is if the GPS chip in the TF is a true GPS chip it should not to rely on a wifi signal to obtain a lock. If the GPS is turned on then it should lock.
I tested sygic gps navigation 11 and signal lock and quality was better than my galaxy s was pretty accurate
Sent from my Transformer TF101 using XDA Premium App
Works fine for me, apart from one minor detail. When I switch from Google Maps to another app, even for a few seconds, then the tablet has to get a lock all over again. There appears to be no way to set the GPS to keep a lock while Google Maps isn't the active program.
That, for me, makes Google Maps near-useless in a moving vehicle. Hopefully other third-party apps won't have this issue.
Google Maps is prety much useless on the Transformer for GPS navigation as a data connection is need. I have heard of people caching a route before hand but ..... Copilot Live 7 is out for android so that is one option. However if the GPS relies on a wifi signal in order to obtain a lock then it is about useless too.

Gps works fine on mine....unlike my icons or Samsung...both returned
gps does use wifi to help gps locate, theres options to turn this off in settings, i went to pick up my dock today and couldn't get a gps lock while in the car with the transformer in my lap(gps status app showed 3 sats but none would lock) just lifting it up 12 inches closer to the windshield made 7 satellites pop up and instantly started getting locks
i think proximity to a window/line of sky is a big factor, and the transformer does have a true gps chip for those who seem to doubt it, also the navigation app keeps running in the background, its better to use that than google maps
No issues with gps here. The bastard finds me every time!

It doesn't rely on WiFi for a lock, it just uses it to allow a faster connection if you don't already have current ephemeris data downloaded. That's a limitation of all GPS receivers -- it takes a fair while to download the ephemeris data if you're out of date or have travelled a significant distance, and without it the device can't get a GPS fix.
You can think of the WiFi location system as analogous to a cellphone being able to use tower locations to help position itself while waiting for GPS ephemeris data.

GPS not working in offline anymore

Hello!
I have LG Spirit 4G LTE H440N
Location is not working, when I turn off data or not being registered in any network after update to v6.0.1. With v5.0.1 things were kind of fine, laggy sometimes, but overall it was working and now with the same apps with preloaded maps it doesn't work at all. Here's what I've done:
- GPS test app locates good amount of satellites "In View" instantly, but it's always 0 "In Use" with no fix;
- This phone was already two times in warranty repairs (both only because of the problem described here), both times HW was changed. First time they changed some part, don't know what that was, but second time it was mainboard, I have a different IMEI now. Warranty is still ON.
- Tried to use GPS in offline with Samsung Galaxy phone, and it works there on Marshmallow.
Can anyone suggest a solution?

Strange GPS Issue

New Sony Xperia X Compact, and out of the box has had a GPS problem. It came loaded with Nougat, and I updated ota each version one-by-one to the latest Oreo 118, then unlocked bl, and flashed Sailfish, and the problem is the same on all.
What it is, is that the GPS signal will get a fix on-and-off after every few minutes, but won't hold steady. Using SatStat app on Android, I saw that the effect was the same with GPS and with network location.
Using a GPS info app, I see that when there is a fix, I get a read on latitude and longitude and altitude, but never anything for speed or direction. Seems like the fix is so brief that there is not a chance to measure it.
It seems obviously a hardware issue, being consistent over many software states, but the hardware is obviously working, so not sure... I would wonder if it was an issue with the carrier, but I used the same sim with the same account on my previous phone and it was fine.
Any ideas?
Thanks
Try GPS Connected app, it's available off Google Play Store.
BTW:
GPS has nothing to do with INTERNET/CELLULAR SERVICES. Your GPS receiver relies on radio waves. But instead of using towers on the ground as the cell phone does, it communicates with satellites that orbit the Earth. There are currently 27 GPS satellites in orbit - 24 are in active use and 3 act as a backup in case another satellite fails.
