Samsung Captivate :: GPS Using Wifi - Instant Lock Indoors - Google Maps
Jul 27, 2010
So before I start, let me say that I have tried this on my wife's Vibrant and my own captivate I get a lock immediately in google maps.
After seeing skyhook in the LbsTest settings I decided to look further into what skyhook is. I read the article below: Samsung to Put Skyhook on Mobile Devices - Midmarket from eWeek
So I thought hey... there are lots of wifi networks around where I live I wonder if it would help if I turn my wifi on.
I get an almost instant lock accurate to 50 meters (good enough for navigation). I have tried it over and over and when I turn off wifi, I get an accuracy of 1700 meters. Turn it back on and get accuracy to 50 meters.
It works indoors and out.
I just noticed that for this to work YOU MUST HAVE "USE WIRELESS NETWORKS" CHECKED under location and security then turn on Wifi (you don't have to connect to any networks). My guess is it narrows down your location based on Cell tower triangulation, then uses wifi to narrow it down.
Here is a blury, crapy, video I made of it:

I posted this in the Captivate forums but it worked on my wife's Vibrant too, so I wanted to share:

i took the captivate on the road and used it as navigation. it worked great for the first 3 hours of the trip, reception or not. i was amazed until i received a notice that my phone internal app memory is low and i need to uninstall my apps. theres no way my memory should be full because i've checked it every few days and i've had 1.6 gb free. all of a sudden i've got 126mb. i'm guessing that Google maps had downloaded the maps in advanced and had just filled up the internal memory. unfortunately i have no clue how to clear the maps. until i can figure this out i cant receive emails, or texts or any messages because the memory is full. does someone know how to clear the old maps from the navigation app? i'm on the road so i havent been able to look at it extensively. i will research it more when i get a chance and post anything i find.

Google maps application is crashing constantly after the 4.4.0 update on my Captivate.At first, I thought it was the lag fix that caused corruption so I re-flashed the stock ROM and it still crashes.The only fix so far is to downgrade to 4.0.0.Is anyone else having similar problems?

After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.

Recently got my first smartphone (Desire obviously ) - still getting used to it My question is about Google Maps - is it possible to use Google Maps with wifi alone? Does anything else need to be turned on and do they cost extra? (I do have 500MB of Data Usage available).

I am thinking of getting a HTC Hero. I am not well up on smart phones. I do like the iPhone but that seem way too expensive compared to the deal I can get on the Hero. On Google Maps, the manual says the phone needs connected toi wifi oir gprs for GM to work. I am going on holiday and dont want to use a huge amount of GPRS in case the bill starts to mount up for international usage. Can the maps for the area I am going to be cached on the phone in some way?
The other question I have is - can the phone be used as a GPS tracker. Say, recording my location every 10 seconds. Then downloading this to my PC and Google Maps when I get home so i can trace wherev I have been. On comparisons between the Hero and iPhone - this is nearly like a religious debate. Is the Hero a fair match for the iPhone.

I have a confession to make.One of the first things I did when I got my Captivate was tried to De-TouchWiz it.I immediately got a new launcher and used lockbot to change the lockscreen.Well, what I'm finding out is that there are some things about TouchWiz that I really like.For example I love being able to change wifi settings etc. on the drop down notification drawer.I also love being able to change the brightness by swiping the notification bar.The one thing that I decided to come back to as a UI element is the Lock Screen.I didn't even give it a shot when I first bought the phone and today I've been using it and I love it.The puzzle message system is just a great tweak and I love how you can just move the puzzle piece into the puzzle hole to go straight to that application instead of swiping the whole screen to unlock and go to the home page.I also really like that you can kind of swipe any which way to unlock the screen, as well as the fact that it's transparent to your wallpaper/live wallpaper.All around, bravo to Samsung on the lock screen.I hope others are enjoying it as much as I am.

I notice that the home screen is customizable but not the four applications on the bottom, the call, email, browser and applications. How would I change those icons with different icons? Mainly the email and browser. How do I turn off or at least severly limit the data that goes to and from my phone. I do not have wireless and am just a bit paranoid about going over my data limit. I got the phone from work and this is my first smartphone so I am a bit nervous about anything I do on it.

Well, my GPS was working alright, but I just need to know what I need for a lock. Recently, I checked, and it wasn't locking on, so I turned on the GPS Test application. I was connected to 9-10 satellites, each with the number 30 next to it, yet I wasn't locking in for some reason. I just don't get what I need in order to get the actual "lock" so that it works properly.

Has anyone noticed the differences in using the two maps in terms of location accuracy? Specifically with GPS off. I don't expect either app to be extremely accurate in finding my location with GPS off, but what's odd is that Google Maps put's me about .25 miles WNW of my actual location while AT&T Maps put's my location .25 ENE of my actual location. You would think that the operating system determines the location and provides the app of that information, but that doesn't seem to be the case (since the two maps are showing different locations).

Has anyone been able to change there lock screen? I am wanting to take it back to the vanilla side slide with answer and mute or even the up and down slide like the HTC's have. Has anyone found an app worth having to do this? I have read about alot of the apps but they get a lot of mixed reviews that they only sometimes work or are bugged? Just wondering if anyone has been able to do this yet and what they used?

Noticed today that when the phone is unlocked with the power/unlock button, that the screen starts off at a significantly lower brightness, but the light sensor seems to then kick in and the correct brightness is then displayed after. This happens for only a fraction of a second, but is quite jerky and immediate.Is this normal, or should the screen brightness remain one constant level from unlock? Of course, changing when it should based on lighting conditions.The same also happens when the screen is about to sleep. Once the lock button is pushed, the screen brightness almost notches down in 2 steps. First at half the brightness, or so, and then off completely. Again, not necessarily smooth, but quite jarring.Again, is this normal of other Captivates?

Is there any way to change the lock screen? I have he Galaxy Captivate. I know there's one app called "Simply Lockscreen" which does work, but it doesn't display certain things like the date for example. And it's a bit buggy it seemed.

An AT&T customer support person told me today that my GPS (even with their AT&T Navigator) will not work with my current SIM card. I have an orange 64K SIM card (63513G) and connect to 3G and HSPDA.
Do I really need a new one or they just trying to force me to get a new data plan.
I have an ancient plan called Media Max (pre smart phone plan) with unlimited data and do not want to change.

I am new to Samsung Captivate. When my screen is locked i see a series of symbols in the upper right corner. I see the same symbols when I pull down the notification bar, right above where it says "No Notifications" if I don't have any. They are @@@^oe@@ I find it very weird. I have been looking and I can't figure out if I can change those symbols or just get rid of them.

My wife and I have had our captivates for just over a month and have loved the device despite the few minor issues that we've experienced with them. I check the boards daily to see all the latest, but didn't see anything on one issue that i am experiencing.
When using the camera to take pictures of my infant son, if i try to take a picture, then another and sometimes a third (infants are hard to keep still for a picture) without closing the camera application, a few times i haven't been able to press the take picture button and have noticed a "lock" icon on the camera screen, then can not exit the camera app at all and need to power off the phone, then bring it back up. Does anyone know what causes this and if it's something that i am doing unknowingly when bobbling the phone trying to positing him for the picture?

If you download the free app called "wifi analyzer", it can help you make an instant wifi connection with the Droid X.
As some of you have reported (and I have personally experienced), it can take too long for the phone to connect/reconnect with your home wifi signal.
Solution:
Toggle on Wifi, then immediately open Wifi Analyzer. For some reason, it forces the handshake almost instantly.
You're connected. And in a fraction of the time compared to if you let the X just run its course.
