GPS

Hey guys, can someone confirm that when using the GPS function it does or does not use data plan? I know some phones such as the iPhone and Blackberry uses data for GPS, and I know the Touch HD is not required as it has the GPS receiver in the device. If someone can confirm this that would be appreciated.
Thanks

Hi!
No the phone has built in GPS Receiver

Awesome, I'm glad that they don't use data for the GPS function, that would be such a killer on data. Thanks for clarifying.

A GPS by definition must not use data. There are other methods of determining location besides GPS, but they are definitely not called GPS. Note that your device, though equipped with a GPS can ALSO use the cell network for finding its location.

So in the case of the iPhone 3g, what would you call that? My dad uses his "GPS" quite a bit but of course uses the data to download the maps. I'm assuming that the HTC Magic has the maps downloaded on the phone already therefore not needing data. Also when the cellphone uses the cell network to triangulate your position, that is not using data correct? I appreciate all the responses and clarification.
Thanks!

I have no knowledge or interest in apple junk.
However, you seem to be confusing the GPS with *what you do with* the data from the GPS. In your example, to me it sounds like it probably has a normal GPS that does NOT use data. GPS does NOT provide maps, pictures, or anything of the sort. GPS provides locational information by comparing the signals from several satellites to generate information like latitude, longitude, altitude, and bearing. This is all a bunch of numbers that the typical user won't be able to make much use of, so along with the GPS itself, you have some program that *does something* with the data. If you use google maps, then your phone will pull appropriate information from google's servers based on the information retrieved from the GPS. Another program that you could use, for example, is "gps status" (available on the market, use "gps status 2" for android 1.5 equipped devices), this will display the GPS information (and accelerometer) withOUT the maps/pictures/etc., and thus will NOT use any data from your data plan.
Regarding the cell tower location method... it doesn't use any data plan data, however, that does not mean that it is free.... check with your provider for specifics. Generally, cell tower location is crude whereas GPS is fine.
Does that help to clarify things?

Yes it does, thanks for your reply.

Other questions... CAn I use GPS software without Internet connection? Or I need all time internet to magic downlaod maps and info? It is any program Tomtom style for android? Thanks.

if someone has, or does release an application that contains its own map tiles, it will be entirely free to use, but will probably cost a fair amount to buy (the map tiles don't come cheap to the developers). Also I would expect such an app to be fairly large, and (if it does even fit) would eat up most or all of the 512 MB you can store your software in.
thinking about it, they could always give you an sd card with the maps and only have a fairly small app in the phone memory. although that's another matter
As long as an app uses google maps (or other online map resources), it will cost you data to use it.

data flow meter

hello to all. my problem is a tricky one: i was wondering if i could find a data register which shows the amount of internet traffic that my phone makes. I recently got a bill for over 100 euro for my internet usage and as far as i know i have done no outstanding data transfer appart from the usual mail and weather application on my htc diamond. I run the standard wm 6.1.
Many thanks in advance.

A inflow cadence is an instrument used to measure direct, nonlinear, mass or volumetric inflow rate of a liquid or a gas. When choosing flowmeters, one should consider similar impalpable factors as familiarity of factory help, their experience with estimation and conservation, spare corridor vacuity, and mean time between failure history, etc., at the particular factory point. It's also recommended that the cost of the installation be reckoned only after taking these way.

[Q] An app to gather network health statistics?

Hi all!
I'm an Android user. I use it heavily for web-based uses - browsing, streaming music and various network-enabled apps. And I'm a little disappointed. The problem appears to be a network issue, but many, if not most, of the time, I can't get a reliable data connection on my phone. GSM is totally fine - never had a dropped call or lack of reception. Just data. Even when I am in a area of strong coverage (full bars; 3G/HSPDA icon showing) I frequently am unable to do simple web access - can't open Google, or an app is unable to do light data connection (e.g. Facebook app grabbing a profile). Sometimes it works fine and when it does, it works bloody fast. But it's that unreliability that is frustrating.
Now, I'd go to my network and ***** about it but they - quite understandably - would be unable to do much about it without a more technical description of the problem. They'd just find some way to blame it on something else, as they do. What I'm looking to do is characterise the problem by gathering some stats on connection reliability. If such data could be collected, I would be able to back up a case that there's something foobarred with the network (or persuade myself that there isn't).
Question is: does such an app exist? I'm not looking for one of the many speedcheck apps; I'm looking for something I can run for a couple of days during which time it tries to make many mobile data connections. It would record success/fail, reported network strength/type, perhaps latency, connection speed and location as well. It would do so once every, say, 5 minutes, to build up a profile of how the reliably I can get my connections.
Anyone know of such an app? If not, I might write one; do you thing such data would be useful?

Sheepish bump...

issue when used with the Sony PlayMemories app

so, I have a couple Sony cameras that have the wifi/NFC feature..... which is great because I can transfer full res photos to my Note 3 wirelessly either wifi OR NFC (NFC method is a little faster). It's a great feature because there are times/situations when the Note 3's camera just can't capture the scene (especially in low lighting environments).
But the problem I'm having is... EVERY single time after opening the app, my phone stops receiving service from the carrier (Wind Mobile, I'm in Canada). I can't make calls, text or get internet/data service. Yet, the "4G" and reception tree would indicate that I have service. The only way to solve the problem is to restart/reboot my phone... which can be a nuisance
I'm wondering if anyone (by any chance) have had this issue, and if it's a bug with the app... who or where can I report this too
thanks in advance for any help

I have no problem with my phone. From Vietnam
But I heard some reports here

Using smartwatch for medical studies and data analysis

Hello
I'm a PhD student in epidemiology in relation to air pollution and I'm specialised in data analysis.
We work with a few dozens of volunteers that will be given some portable sensors.
The sensors can measure GPS but aren't as precise as a A-GPS (with google services).
I need to be able to precisely track localisation of volunteers in order to know where they are ; street/inside/etc.
We also want a general activity indicator, and hearthbeat plus podometer could be very interesting too.
Since I'm not lucky enough to be given Apple watches, I found smartwatches on aliexpress that are bellow 100$ and that can do all of the above, that has GPS, LTE, sim, and on board sensors. In France we can provide every volunteer with a 2€/month sim card.
Three problems : It's often very hard to get the data measured by those watches by the included app.
Also, I want to be able to measure data on an occurence that fits the battery limitation.
For example I only want GPS data every minute. This consumes way less than navigating with Google Maps directly on the watch for example.
I don't have any background in software developpement, but I happen to know python, and made a few GUI for Windows.
Basically I want only a fit-tracker that will log every data every X-minute depending on the limitations.
So I have a few questions ;
Do you think that by developping on those watch I could be able to pick the data even tho it would be a chinese watch with no documentation ? Maybe android lets you have full access to the data ?
Is this feasible or does this require too much knowledge ? I guess Android watches are way less documented than smartphones.
Any recommendations?
