i780 - Cannot operate camera with GPS

why is that? what about taking pics for GPS applications (such as Run.GPS)
its so annoying to stop the GPS and then take the picture!!

I have the same problem, tried something with te gps settings and this is the solution:
GPS - Original settings are GPD1 with COM9:4800 and checked auto managed.
Set to COM8 for programs and hardware at COM9:4800
Then the camera wil function properly

I have the same setting with you but can't use the camera when GPS running.

yep
you cannot take a picture once GPS is on - whilst in other phones its no issue
there is also something with alarms and GPS which get along together
go figure...

This really is lame, so no auto trace gps with cam options ;(
lame that samsung didnt fix this, these are small annoyances what would make me go to another brand phone.
I didnt find any solutions for this problem..

thyis and so many other issues on this phone
the most simple matter - there is no cable to do hot sync and charge together...go figure?
battery is so low when GPS runs, I cannot complere a singe bike trip with it

I have a theory about why GPS on TP2 cannot fix satellites quickly

Or, in my case, cannot get a fix at all in most places.
The only place I can get a fix is an ideal spot near my office, in an elevated garden (on top of a shopping arcade). With nothing taller than me in a 10m area, and nearest buildings only two or three stories high, I can view 16 satellites and immediately get a fix on 8 of them. In all other places, no matter how long I wait, will see 16 satellites with 0 fix.
With more testing I found out to get a good signal strength in normal situations, I have to do either of these:
1. Enable flight-mode (i.e. turn off all other wireless communications).
2. Slide out keyboard.
Doing both will give me a fix within 5 seconds in all out-door or near-window locations. Just enabling flight-mode results in less than 20 seconds. Sliding out keyboard has a lesser effect, but usually will get a fix within 2 minutes.
I used HTC GPS Tool and NaviComputer in the tests.
With HTC GPS Tool:
- Flight-mode OFF and keyboard in, in the ideal spot I get about 50% signal strength for the best satellite.
- Flight-mode ON, signal strength goes up to 80%. Sliding out keyboard has no observable effect with flight-mode ON.
- Flight-mode OFF and keyboard out, I get about 60% for the best satellite.
So it seems the true reason is the GPS antenna in TP2 is poorly located, getting interference from phone antenna and the machine itself.
If you own a TP2, could you test it and tell me the results? (should observe stronger signals even if you don't have a problem)
If most people get same results as me, I'll send a report to HTC. I absolutely love QWERTY keyboard on my TP2, and my next model will definitely have one. I want HTC to learn about this problem (or acknowledge it) so future QWERTY models won't have the same defect.
Thank you in advance for your time to perform the tests.

good test, strange result

Well I never have gps issue with my tp2 so I don't understand your problem

It also depends a lot on which radio you use. Some radio's give you a faster fix and some don't.

As I said in the first post, I observed improved signal strength with either flight mode on or keyboard out.
Even if you have no GPS issues, you may still get better signal strength if you perform the test. You can view signal strength with HTC GPS Tool. That's all I ask of the community - to see if TP2 has a design defect that weakens GPS signal reception.

I'm using this Radio from HTC - version is 3.46.25.30. The HTC Diamond 2 I mentioned in the first post has an even older radio version, yet receives signals better than my TP2 does, until I enable flight mode or have keyboard out.

im using the latest radio and i get a fix in a few seconds. it took ages on other radios. its very deja vu with the touch pro. the gps sucks up until a certain version of the radio.

I logged the NMEA data with HTC GPS Tool, and without flight mode and keyboard out, most NMEA sentences contain blank fields. GPGSV reports 16 satellites, but GPGSA will report status 1 (no fix available). Also GPRMC failed to return time.
If I slide keyboard open, I could see more data fields - GPRMC returning time for instance. I'm pretty sure sliding out keyboard or enabling flight mode have no effect on how the radio driver interprets GPS signal received.

Could you tell me your version, is it official? Where did you get it (I assume here in XDA? I've seen plenty of custom radio ROMs)?

You can get the official radio's here. (There are no custom radio's) http://forum.xda-developers.com/showthread.php?t=549939
Just try some radio's for yourself. There is no best radio, because it depends on which place you are etc. So what works best for me is not necessarily the best for you
ps you need to have hardspl installed.

you will not be able to connect to all those sats no matter what equipment you have. in total "There are 30 GPS satellites" so I AM GUESSING here. that there are around 15 on each side of the earth. and if you divide it for the top of the earth and the bottom that leaves 7.5 sats so if its showing 16 there must be one extra uneven one in range. so that makes 8 connectible to. im pretty sure that you cant connect to a sat thats on the other side of the earth. or on the bottom.
but thats just my research and my thoughts. i could be wrong. but i dont think i am.
so in theory you should only be able to connect at 8 sats in any one time. OR it could just be that out of the number of sats your connected to. if any other were added it would give you a wrong position

to lock on satellite with the htc gps tool takes about 1 minute with data communications on . in airplane mode it takes about 5 seconds. this is consistent for me.

I've tested several Gps apps both on Winmo and Xdandroid.
Something is sure: apps make the performances
On Android, Google Navigation is 5 time slower than Navigon (same place same conditions of course)
On Winmo Waze is 10 time slower than Tomtom and lost the grid even with good conditions.

In the UK GPS works fine from my car, inside not so good. It's better in open not urban areas.

I will at times have both my TP2, 6.5, iGo8 right next to my Asus R600 (standalone GPS) and the Asus will fix a satellite within a few seconds, while the TP2 usually takes a good 2 or 3 minutes.
I always attributed this to the type of receiver and antenna, but that's just speculation on my part.

With QuickGPS data, my TP2 gets a lock within seconds, even indoors.
You MUST keep this data up-to-date, lest lock times suffer.

[ION] Phone freezes after turning on GPS (ICS ATT ION)

Recently, I noticed that my phone always freezes after turning on GPS. Right now, I am still running it on 6.1.E.3.7.
I've tried several apps as well as GPS test in service menu, the results are all the same, the screen blacks out and phone automatically restarts..
I've also purge the GPS assistant data, no use..
However, if i open GoogleMap with GPS off and then turn GPS on under the request from Googlemap, "this app requires GPS service blablabla..", the phone won't freeze.

have you had this problem only on 6.1.E.3.7? (if yes then proceed)
i suggest you update or rollback to another update, it may be that that version is causing the crash, it may be fixed in a newer version if avaliable

[Q] Intermittent GPS Operation

When I start GPS operation I get a FIX very quickly in 2-5 seconds. Then I operate my navigation program and it's OK without any issue.
When I close the navigation program and leave the GPS status ON the device turns OFF the GPS as it should and again it's OK.
And now comes the problem.
When I open again my navigation program the GPS comes on but cannot detect any satellite. I Use GPS status program and it shows an empty screen without any satelite detected.
To overcome the problem I turn OFF the GPS, Wait for 2-3 minutes and turn GPS back on to get a very quick fix.
Has anyone encounter such a problem?

I leave my GPS always on, sinds it is only being used when needed. But never had this problem. I would try out some GPS apps to monitor. Otherwise you may have a defective or bugged out GPS and then I would return for warrenty. But if there is anyone you know with the same device see if it also happens to them with the same use senario. Otherwise you should contact the app dev.

Problems lately with GPS

Just recently over the last couple months, I have been having a problem with getting a good gps signal in programs such as Waze and Google maps. I have done all kinds of searches and many mention to go into settings and in location settings, turn on High Accuracy. That option is bo longer available and not sure if it was eliminated in Pie. I have been doing all the latest updates and believe I am current. The only thing I have been able to find is to go into settings, then Biometrics, and there I found location. The only choices under Improve Accuracy is to turn on Wifi scanning and Bluetooth scanning which I have done. There no longer is a choice of High Accuracy and the ability to turn GPS on or off like I had in previous phones and previous versions of Android. I have even tried turning on High Performance under Battery Power settings and turned off any choices to optimize battery or disable apps. I ended up downloading 2 different GPS apps from Store, GPS Status and GPS Fix/Optimizer. I will normally use Waze or Google maps through Android Auto. I can tell when there is a problem when the position indicator keeps bouncing all over the place in Waze and cant find exactly where I am. When that happens, I will check on GPS Status and it always shows that it is having a problem acquiring the satellite signals. I will then open up GPS Fix/Optimizer and on the home screen, there is a button that will say Service Off. I press it and it will then read Service On. Switching back to GPS Status will now show that it is starting to acquire multiple satellite signals. When I switch back to Waze, now it is able to show my exact location and begins to work properly.
This is driving me nuts. I never had this problem on any other of multiple different phones or Android versions. I can get GPS working but have to jump through all these hoops each time and it sucks. So what other steps can I do to be able to fire up Waze and have it find me right away?

It's not just an Android Auto thing, it happens with GPS in general. There have been many posts about it over on Reddit in the Note 8 Forum dating back to March. The best fix is to just toggle location whenever you notice that GPS isn't working.
The scary thing is not only has Samsung not even acknowledged there is an issue, newer phones are also starting to have the problem. Just saw people complaining about the same thing in a S20 forum. Just like our issues, they started after an update.

Did you ever find a fix for this problem ? I am dealing with this too and have been for a while. GPS when using as a phone is no issues at all but, once you connect Android Auto, it's a mess. Very hit or miss and even if I hit where it works, it will drift off and require me to unplug/re-plugin my Note 8..
I posted to a few other places on this issue, nothing has solidly fixed this. Otherwise my note 8 works fine, so I no reason right now to upgrade, till the phone I want drops a little in price.

Anyone else figure this problem out ?

I still havent found a fix. Here is another thread I started on the main Galaxy Note 8 that produced a lot more discussion but sadly, no fix yet.
https://forum.xda-developers.com/galaxy-note-8/help/recent-gps-problems-t4058849
For me at least, it seems like it may be an issue between Android Auto and my Chevrolet. Still not entirely convinced but folks over at Android Auto claim that there is a communication problem with Android Auto trying to communicate with the internal gps on my truck. Supposedly even though I dont have traditional on board navigation, there is still gps communications going on. I believe that with Chevy, it is the onstar system. Android Auto is programmed to utilize vehicle gps because it is supposed to be more accurate. Unfortunately, if that is the case, and there is constant communication error between the Note 8 and vehicle, the result is that the apps in AA like Waze and Google maps continually have location errors. I inquired why AA couldnt just allow users to utilize the phone GPS as an option and was again told that a vehicle gps would be way more accurate so that option isnt available. When unplugging usb from vehicle, it defaults to the phone GPS and begins working again almost immediately. So is the problem with AA programming or communication problems with my Chevy truck? Who knows. Sometimes they communicate just fine from the get go but other times, not so much. I just wish the problem could be fixed. I would be leaning towards AA programming as this does not just happen with Chevy vehicles but AA just passes the buck.

Yep, saw that thread as well and the one on Android Auto's site, I even replied to it. Wishing there was a solid fix here but, no... I have a Lexus LS that I added on a 3rd party Android auto device on. I had this same issue when I had a 2019 Ford with Android Auto as a rental. I figured 6 months later (I just put AA in my car about 2 weeks ago) it would be resolved by now.
Not 100% sure it is the GPS car thing you were told, as other phones plug into Android auto and have a seamless experience if this was the case, all phones would have this issue. We are using the same software. So why is the Note 8 different ? Well, I hear this effects other Samsung phones but, none as bad as the Note 8. Newer Android 10 even Samsung phones do not report this issue, as far as I have heard.
Oh, well the quest goes on... If you find something, please drop me a line....and thanks !

"Me too" - Driving me crazy. Toggling Location services off and on sometimes helps, but not always. I'll be moving, and the map doesn't reflect any movement.

Toggling when driving is not a good idea, Normally unplugging and plugging back in works just as well. Funny for the last week, it was working fine (get lost when in a lot of trees and sometimes not recover but, on the highway it was perfect), till this morning and it was a mess.
There was an update for the Note 8 on Verizon a week ago, I need to double check all the power saving features and make sure they are fully disabled...

I had also started a thread on the Google Android Auto community back in May where the developers monitor posts. Just recently (about a week ago) it seems they are acknowledging that there may be a problem and posted they were going to send out emails to several that were affected by this. They gave directions on how to forward a bug report to them when the problem showed up. I was one that received the bug report email. I have since submitted 2 bug reports to them but have not received any kind of reply. Hopefully I hear back sometime soon and they are able to identify exactly what the problem is. If I do, I will post their response...
