GPS itself does not need a network connection to any server to work. It just needs a signal from a least 4 GPS satellites to calculate a good position fix. There is also the GPS Almanac, which basically provides future data on where the satellites are expected to be in a given time in the future, usually up to 7 days. This can be used to speed up the ...

If you simply want to find each other, I would use Google Latitude, included in Google Maps, which allows almost live updates (about every five minutes-ish, usually), and gives all the options of Google Maps, including just a few clicks to see a map or use the built in turn by turn Navigation to find each other. See this similar question for some other ...

No. Bad cellphone coverage decreases battery life because the phone has to transmit with more power to be able to communicate back to the cell tower. It's like when you can barely hear someone hollering at you: you shout louder too to make sure they can hear you. But GPS is a one-way signal: the phone only receives it, it doesn't transmit anything. It doesn'...

if you believe that your parents are tracking you with your android.do this 1:backup your favorite apps. 2:factory reset the phone. 3:encrypt your phone.(this way nobody else can access your phone) 4:for extra protection you may add pin so that you can lock down parents from accesing your settings. 5:if you are going a step further you ...

GPS generally affects battery life significantly only when used (in standby, its energy consumption is neglible, usually far below 1 mW). But when it tries to aquire a fix (i.e. you want to know your current position), it might reach consumption values comparable to your device's screen (~500 mW). So in your described situation, it might influence battery ...

Dan already pointed out that this is more a social problem. Talk with your parents, express how you feel about this. The feeling of being constantly monitored is sure not very pleasant. That said, the only way to make it hard for someone to monitor the location with the help of your Android phone is by ensuring that you have a clean initial setup and a ...

While a data connection might prove helpful for a faster fix (see: AGPS), it's not strictly necessary to have one. There a a lot of "Offline GPS Apps" available. I personally e.g. used Locus Maps successfully for that in the past, but there are plenty of similar apps available. Tracks can be stored on the device, of course, and do not need to be sent to a ...

GPS - all GPS systems get signals from the satellites. They never send data to the GPS satellites. Your phone would need a much larger antenna to send a signal to them. Systems like OnStar do send your position back to their servers. Google servers do get your position information so they can calculate directions and pull in the tiles for the map. The US ...

There are some solutions available on the playstore. One of them is Traccar (the link belongs to the Android client), which logs to a traccar server you can define. The server software is open source (at least that's what the app description claims), so you can use it on your own server. Written in Java, it should run on most operating systems. For more ...

No, there is no way to track it without having it configured in some way to connect to a wireless source of data. Without a SIM card you can't do that via a service provider and without having the Google account configured (and thus an authentication token that identifies your phone) you can't do it via WiFi (if you have it turned on).

It is actually not the hardware at all. There is a special file in the android system called gps.conf. This file specifies the GPS servers that the device will use. Each manufacturer wants to use their own special GPS servers instead of the main ones from Google (some have different values for different devices). This means that different devices connect to ...

It's likely due to the fact that GPS is simply not very well suited for getting precise altitude measurements, and never has been. Certainly not typical consumer-grade chips. Garmin suggests that variances of up to 400 feet are to be expected in their devices, for example. It's just a geometry problem. With that in mind, I would doubt that Android has much ...

I had exactly the same problem with the gps data on my android smartphone. I live in the UK and noticed that the altitude displayed was consistantly 40 - 50 metres higher than the mapping showed. I too thought that this was a lack in gps accuracy. In fact the answer was that the gps was showing altitudes related to the wgs84 global spheroid whereas the UK ...

If you have access to the Google account on the phone, you can use Google's Android Device Manager to locate the device. This requires the phone to be powered on with location services enabled. This will notify the phone as well. If you do not have access to the Google account, you need a preinstalled tracking application, like Google+. Some more examples ...

It's not entirely clear from your question what exactly you mean by "tracking". If you only wish to record a log of where the device has been (so you can look at it later, or retrace your own steps), then you don't need any internet access for that. The device just receives the GPS signal, calculates its position, and saves that position to a file every so ...

GPS is a passive system. There is a constellation of satellites in orbit, with atomic clocks on board, that essentially just shout out their identifications and the time, for anybody who will listen. A GPS receiver listens for the signals and uses the differences in times that it's hearing from the different satellites -- due to speed-of-light delays and ...

That's a little confusing: No SIM = no SMS. No network = no connection = no communication. GPS is only a receiver, it does not send. That leaves binoculars as only tracking method then – which, besides, even works with devices not featuring GPS. As long as visual contact is possible, at least ;) Apart from that, I guess we've got an XY problem here: "good ...

A switched-off phone is, well, switched off. That means all its radio modules are off. That means that it is not connected to any external equipment. That means that you cannot track it. BTW you also cannot track your phone if it's in flight mode (I mean here full flight mode with wi-fi switched off).

Basically I want to set up a widget / shortcut on their home screen .... There are a number of social media apps that can do this but they are not one click as you mentioned besides setting up a widget is not possible Hence, suggesting automation as an alternative I prefer Macrodroid, being easy to learn and free (upto 5 macros). You would need to install ...

Well, you can try using avast! Anti Theft, but you must first install avast! Mobile Security because it comes bundled with it. Can be considered as bloat because you don't seem to need the anti-virus features. But avast! Anti Theft is integrated online, which means that you can control your phone using the avast! web site, apart from controlling the phone ...

The best option is Google's My Tracks Follow the link and see the features yourself. Everyhing you want is there. And the best part is it's free!! Hope this helps

Each app on Android stores its data on internal storage by default, below the /data/data/<package_name> directory. Due to the sandbox princip, except the app itself and root nobody has access to that if not explicitly defined otherwise by the developer (e.g. Skype currently has a serious security flaw giving everybody read/write access to all its data, ...

You can check this on google location history.... and I can attest it isn't entirely accurate (more so when the points are several kilometers apart, and I probably walked at supersonic speeds) As @flow has said though, its more of a socio/cultural issue as a technical one - I shouldn't be judging someone elses culture but this kind of unfounded ...

Answer to both is: "Depends". Airplane mode What is that nowadays, where air planes allow you to use WiFi and Bluetooth? Don't say this is an unrelated question in this context. Not only does the term originate there, but it can be as variable as how each airline deals with it: $ adb shell settings get global airplane_mode_radios cell,nfc,wimax,bluetooth,...

Go to Settings, then Location. Find Google Location Settings and individually switch off both Location Reporting and Location History. Underneath Location History, select “Delete Location History” to wipe clean the cache of locations. Repeat the steps for every Google account you have registered. Note that disabling all location-finding features will throw ...

Trusted Contacts is the solution you're looking for - it's an application made by Google, which allows you to share your location with friends and family and integrates with Google Maps' location sharing solution too. Simply install the application on the family member's phone and make sure you are selected as one of their Trusted Contacts. Whenever you ...

I'll neither say yes or a no to this question. :) Debateable - if you're acquiring a GPS fix through Wifi, you will not get it in the woods or mountains :) However, if pulling 3G data across in order to acquire a fix, the question then steps in, how much battery juice is eaten up when trying to get a good "proper" signal (in between switching masts to ...
