For users I think that it's a placebo -- the Sprint ROM didn't include QGPS. I have made cold boots with a new ROM and without QGPS and returning the same sporadic (15 seconds to 10 minutes) lockon's as setups with QGPS installed and apparently having updated the data for the GPSOne chipset.

I don't believe that our GPSOne setup offers WAAS.

Again, I don't believe that there is a magic bullet to get many of the units more functional with their GPS. As have noticed when comparing my dad's to my Titan, there are hardware differences returning varying GPS performance, and it's a luck of the draw. Mine, apparently returns excellent performance for times to lock-on, but this is not nearly as precise and timely as my i-blue 737 bluetooth receiver. The internal may be a nice feature -- when effective -- but its antenna and GPSOne chipset cannot equate to the performance of a decent external GPS receiver. Rather than mess about and cross my fingers (reset the device or not? wait and pray?) for an internal lock-on, I'd much rather quickly turn on my external bluetooth receiver placed on my dashboard and know that I WILL have a precise satellite lock within seconds of starting up my mapping software.

Even on a unit without the apparent hardware flaws and the internal GPS working as best it can, this GPS is a nice toy but not up to par to alternatives.

Hey listen...lol...I never said that I actually believe that anything I do has anything to do with getting it to work right...I merely posted EXACTLY what I do each time because it works perfectly for me each time I do it. I've tried leaving out a step or two from my explanation, and it doesn't work. So SOMETHING I'm doing must be right. If people don't want to try it, they don't have to ;-)

As for using this unit has a primary gps, helllllll no. I didn't think GPSOne had WAAS, but I do it anyway just for ****s and giggles. I use a Garmin Nuvi 350 in my car for my primary gps with sirf and waas. My titan gps is just for fun.
[Mogul, XV6800 ROM Development] scorp508:
Ok... I think I figured it out for my device. For some unknown reason in the External GPS settings my COM4 setting on the hardware tab is not being saved. It keeps reverting to <none>, and causing the ****tyness. The baud setting is staying on 4800 appropriately.

If I do this, it works.

1. Go into External GPS and confirm software tab is <none>, hardware tab is COM4 and 4800 baud.

2. Open QuickGPS, download the data.

3. Launch Google Maps or Live Search.

4. GPS locks on in about 5 seconds with great accuracy.

I'll try to figure out *when* the COM4 setting is being lost and if there is any predictability to it.

I just drove home from the gym locked onto 5 satellites. Peeking at the screen now and then it seemed like anything above 25MPH had the GPS one step behind me. gcincotta, doing 55MPH up Route 1 by Kowloons showed the GPS beacon about 150 yards behind me. Then all of a sudden the map itself wasn't updating even though I had EvDO and full signal strength going. I drove off the edge of the road into the white background never to be found again. :D:eek:. Both google and live maps weren't updating the map in the background for some reason, maybe driving was causing too many data refreshes to attempt to happen? It is working again right now sitting here in my living room.

Its still overcast and rainy right now, maybe with sunny skies and a couple more sats locked in it will be better. Walking it would have been perfectly fine... but who knows if I could actually get any sats to lock on in Boston. I definitely wouldn't rely on it for driving around somewhere I didn't know, but if I can get a quick "You are here, idiot." then that is perfect for me.
[Mogul, XV6800 ROM Development] aph:
I mean hard reset. I could soft reset 10 times with dcd and it wouldn't pick up anything once it had gone dead (TomTom GPS status showing only gray satellites and not getting a fix.)

nueROM is slightly better. Still blacks out (same as above) sometimes, but a soft reset will fix it. And yes, I use GPS quite a lot (used a BT receiver prior to 3.27) and it's frustrating when it doesn't work.

Haven't tried stock 3.35 yet but will stick to nueROM unless it craps out on me too.
[Mogul, XV6800 ROM Development] JerrytheGreat:
Scorp,

Isn' tthis backwards? Mine only works with software set to com4, hardware set to none (using DCD 3.0.1, Alltel)
[Mogul, XV6800 ROM Development] scorp508:
I'll try mine that way and let you know how it goes. I drove 50 miles yesterday with mine set the way I originally mentioned and it was the same deal. It locked onto 3-7 sats the whole way. I noticed if I only had 3 or 4 sats my location was off a little, but as soon as it had 5+ the accuracy was much better.
[Mogul, XV6800 ROM Development] aph:
nueROM is crapping out too, no fix even after soft resets (waiting 10-15 minutes for one). Disabled aGPS and it got a fix once, then stopped again.

This is very frustrating
[Mogul, XV6800 ROM Development] mr.ellsworth:
I used Live Search yesterday from Springfield, MA clicked on Directions start point set to Current GPS then set my destination to my friends in Merrimack, NH and it took me there flawlessly. It was a little over 100 miles. Tracked down the road perfectly. I have never done anything with GPS settings other than click enable GPS or Use GPS in Google Maps and it has always worked.

im really reluctant to post because of the success ive been having. and not wanting to jinx myself at all.

after similar results to everyone else here for a month or so, in terms of reliability(or lack thereof). the past few days have been great.

what ive been doing, is using holux gps viewer first, if i havent locked in a while then after opening it on com 4, i click cold start, if ive had one recently but its been off for a little while, then warm, and if im coming from a lock...rare...then click hot.

once i see the lines begin to scroll on the initial page, i know the gps is looking for a lock, and is not ahving some issue. if its not going anywhere, or doesnt seem to be responding, then i soft reset, and try again. from cold start

by looking at the status page, im able to see if im coming close to a lock or not, and if its worth it to wait, or try some other step.

once i have 4 blue bars, then i start whatever other program i wanted to use gps with, and i get as many satellites as i had blue bars.

ive used this to start google maps, gpstoday, and navizon, all without issue by starting and being a little patient with gpsviewer.

my preference, is that its better to stare at gpsviewer looking for a lock, able to see that its actually trying, than staring at google maps or whatever application, where it just says "seeking..." or whatever.

thats been my experience, hope it helps others
[Mogul, XV6800 ROM Development] gc14:
You could stare at gpsviewer if you want...or you could do what I do and start gpsviewer, minimize, put gpstoday in persistent mode and check the box in the options that says keep device awake while in persistent mode. Then just put the phone down for a little and check in a few...if the square is green on the today screen you're good to go, if not, then wait longer.
[Mogul, XV6800 ROM Development] dagurasu:
I agree about using gps viewer. Sometimes I feel hitting cold or warm start there does something useful, but also it may just be I like to stare at it and can actually tell if it is actually making any progress or if it needs a reset.

Hardware variation or not, I don't believe these problems can't be fixed by software workarounds. Does a soft reset do anythig to the state of the hardware that cannot be done by software? I mean the slow locks some experience might not be fixable, but the need to reset should be.

Oh well, I was hoping to hear better things. From what I hear there is no reason to expect stock to work better than dcd 3.0.1 though, which is really what I was wondering for now. I really felt the leaked rom was better in some of ways, but not enough to bother flashing back to it.

to gccincota, no offense, I understand you're just saying what worked for you.
[Mogul, XV6800 ROM Development] gc14:
Nah, I was just saying instead of wasting time staring at the screen, he could minimize it and just let gpstoday do its thing...and just keep checking the box on the today screen...
[Mogul, XV6800 ROM Development] roninld:
After going to DCD 3.0.1 from DCD 2.3.2 (actually went to stock in the process), was having issues with my GPS as well. I had done the hard reset by holding the 2 soft keys and the reset button, and was still having problems.

I just did a Clear Storage under Settings, System Tab, and GPS is working much better so far. One note, after doing a Clear Storage I was forced to reprogram the phone by dialing *228 opt 1 because when it came up everything was blank.

my alltel 6800 consistently shows me in the Himalayas using google maps and live search. I'm using the sprint radio, DCD 3.0.1 alltel rom, and have tried quick gps, gps viewer. I'm in Florida.....NOT THE HIMALAYAS!!! Any ideas??? The ROM smokes otherwise.....Thanks DCD!
[Mogul, XV6800 ROM Development] scorp508:
Well my GPS performance has flushed down the ****ter. Now I can't even get a single satellite to lock after waiting 15 minutes. This is using COM4/4800BPS on either the software or hardware tab, neither works.
[Mogul, XV6800 ROM Development] Gilliland:
I don't understand this use of the hardware tab. In my experience, it is not possible to set the hardware port to any value other than "None". If I set it to any value, then click OK, it gets immediately reset back to None. It never retains any other value.
[Mogul, XV6800 ROM Development] Gilliland:
GPS won't work in Caribbean

I spent the past week on vacation in the Caribbean. There were no Sprint towers handy, but I figured I might be able to use the GPS if I set it to standalone mode (GPSMode 1). Unfortunately, it did not work. I used GPSViewer just to see how it behaved. I found that the GPS found a lot of satellites - sometimes as many as twelve! But it never once got a lock on its position. It told me "No Fix" no matter how many satellites it had acquired. I waited half an hour or more in some cases hoping it might lock on a position, but it just never happened.

I thought that something might have gone wrong with the software, so I did a complete hard reset and started over. Same result - lots of satellites, but no fix.

I brought it back to the US and tried it here (same standalone mode, no change in settings), and it got a fix within 30 seconds. But only if the phone is turned on. If I leave it in Flight mode, it still can't get a lock.

Looks like "standalone" still depends on access to the Sprint network for some aspect of its function.
[Mogul, XV6800 ROM Development] Keystone:
The GPS hardware will work anywhere in there world and there is no reason why your carrier network is necessary for GPS functionality. If ephemeris data is downloaded over the network rather than from the satellites then that can speed up a satellite lock. I do not have have a data plan and have consistently disabled the assisted feature of the aGPS hardware. This does not prevent me or others from achieving a GPS lock upon satellites. As this thread demonstrates....other factors do....... Unfortunately it sounds like you were simply unlucky in experiencing the sporadic nature of our Titans... Location wasn't the issue -- just bad luck with timing and your device.

Remember that weather can impede signal reception. Was it clear skies?
[Mogul, XV6800 ROM Development] Gilliland:
No, that won't explain it. I had completely clear blue skies. I had solid reception of at least six, and at times as many as twelve, satellites. And I tried this experiment at least six times over a three day period. The satellite data was being received, but the Titan GPS simply couldn't do anything with it.

The minute I got back to the US, it locked on its location without difficulty. And that WAS under cloudy skies.

Have you actually tried using yours in the Caribbean? Or are you just stating what you'd expect to happen?
[Mogul, XV6800 ROM Development] Keystone:
Myself and others have experienced that very same behaviour.

No, I have not brought my phone down. We have yet to isolate a single cause to the problems (need to reboot to reset, etc.. as well), but it is due to the devices's hardware/drivers rather than your conclusion of GPS not being global. I was just stating the satellite reality that the location you were at did not negate the ability of GPS.

As others (myself, right at this moment) experience the same behaviour as you did, it makes far more sense to place blame upon the hardware rather than some mysterious GPS void in the Caribbean or being away from your home carrier. Sometimes many satellites are visible and the strength may read as being strong, but no lock is attained. That sucks, but that's an apparent aberration of the Titan's rather weak and inconsistent GPS performance. Possibly the device gets confused when re-initialising and/or finds itself a great distance from the memory of its previous lock? You are not alone with such problems.
[Mogul, XV6800 ROM Development] dagurasu:
I got a gps lock not just in airplane mode, but actually IN an airplane and certainly with no data or phone signal (I hope the feds don't come after me... I think this is legal use of a phone on a plane, since it's entirely passive). I couldn't get a map position because my maps come over the network, but I did got longitude and latitude with no problem. I did ask google maps for a map and it registered the gps location.. showed the blue dot and then tried to dowlnload maps but failed. I turned off google maps and gps. Once on the ground google maps, before asking it to use gps, loaded the map for where I had been because it was still the last location stored in GM. So in the end I got the information I wanted... ie, what was outside the window.

Anyway, the device is absolutely capable of working without a data connection.
[Mogul, XV6800 ROM Development] Gilliland:
That theory may turn out to have some basis, and it may also explain why the GPS is effective with access to a tower, but not otherwise. It may be that the GPS is able to resolve the satellite data only if it has a "starting point" - either by using its last known position, or by determining an approximate location from the tower network. If it can do neither (as in my case), the GPS simply fails to work.

If that's the case, it should work fine in standalone mode as long as you haven't traveled a long way since the GPS was last enabled.

In any event, I don't understand the limitation. GPS technology isn't supposed to fail in this manner. Standalone GPS units don't depend on any "hints" to get an initial lock, so why should this one?
[Mogul, XV6800 ROM Development] aph:
I'm back to using a standalone unit over BT...

Will try a stock Sprint flash as a last resort and report back

Not Working

I have installed many ROMs also and still no gps

For some reason everything seems to work...(as in the gps being read)

Except when i start up Google Maps my gps doesnt respond

I just get a message saying gps active/seeking sattilites

I dialed ##DEBUG# and the gps data says N/A

Also im outside my house with clear skies so i know thats not the problem

I DONT KNOW WHAT IM DOING WRONG!!!:mad:

I have gone thru a few Sprint Moguls and still have 3 of them in front of me. I can update the AGPS data with the latest QuickGPS download so that they all read 7 days 0 mins. Once I fire up either Google Maps or TomTom all 3 devices, I have one unit that gets a lock within 10 seconds, another that gets a lock in roughly 30 seconds, and lastly one that locks in about 2 minutes. This has been done at various times during the day after a fresh reset and recent AGPS data download to all phones.

The phone that locks the quickest also has a considerably stronger signal in TomTom than the other two phones.

All phones were flashed the same way and only have stock DCD 3.0.1 ROM other than the GPS software (Google Maps, and TomTom). It just goes to show you that the hardware variances between the units are large! There might be nothing wrong with your phone for taking so long to get a lock, if ever. Just a weak GPS antenna or one that is not connected to the mainboard properly during manufacture/assembly. I guess they are all within manufacturer's tolerances? I would try to cherry pick one, if a Sprint store allows for it.

Sadly for me, the one that is slowest to get a lock is also the one that has a perfect screen that is absent of the white LCD bruising, and this one is the oldest of all of the phones.

any one have any idea why my gps would quit working after i did a hard reset? it always worked before then too.... :(
[Mogul, XV6800 ROM Development] aph:
Tried the stock Sprint ROM (actually just tossed the old phone and got a new one). The GPS worked but intermittently.

I figured if my GPS wasn't going to work I may as well have a clean phone, so I flashed key's cleaned v.1.3.1. Just for fun I also installed GPS Viewer since it seems that starting with it is what a lot of people who have good experiences have in common.

Ran QuickGPS, and ran GPS Viewer sitting in my living room (where I've never had a signal before, even when the GPS would work otherwise outdoors). It acquired a cold start lock in 4 seconds! I'm still shocked...

My recipe for success:

1. use key's cleaned v1.3.1 kitchen

2. cook it with QuickGPS

3. prime with GPS Viewer

I will revise this over the next few days if I determine that some steps are not needed.
[Mogul, XV6800 ROM Development] dagurasu:
As I recall somewhere under settings/device id, the ame place you see rom versions, there is also a hardware revision. Can you check this and see if they are all the same? Maybe it's actually possible to figure out which phones are bad. Also you can find a manufacture date if you open /windows/epst.lnk and click chose view. If we figure out which ones are bad, there will be a stronger case to go to sprint with to ask for a replacement.

Over the weekend I went San Gabriel Canyon in California and although I was not able to get a cellular signal, I was able to receive a GPS signal using Tom Tom Navigator 6.

I used WiFiFoFum to prep my GPS and in about 5 to 10 seconds I got 5 satellites and was able to use Tom Tom to search for tourist attractions, restaurants, and even my way around the mountains.

I was hiking out in the San Bernardino mountains near Palm Springs, using Garmin XT Mobile. Phone was off, but GPS working perfectly. No problems. Had the phone forced to on to track my progress. Only problem I ran into was when I accidentally pressed the power button, hibernating the phone, then messing up the GPS when it came active again so I had to soft reset.

Using DCD 3.0.1 without any prepping tools.
[Mogul, XV6800 ROM Development] bdokka:
Live in Seattle, have DCD's 3.0.1 and GPS was working flawlessly. Went to Dallas/Fort Worth last week and it took 15 minutes just to find a network signal initially and the same after doing a soft reset. GPS only worked once during the whole trip and only for about 10 minutes. Once I got back to Seattle, GPS would not work for 3 days, it is now working intermittently. Nothing like it did before the trip.
[Mogul, XV6800 ROM Development] indeo:
Not sure what this is worth to anyone, but I would like to state a theory I have. And also, I don't know if someone said this already, I didn't read every single post of this thread, but most of it.

First -- I believe that the GPS radio in these phones have a lifespan of sorts, as in they dye off sooner or later and become intermittent, inoperaple, etc.

Also, I'm on my third 6800. My first one I bricked (oops) using a very experimental ROM that I should have never tried to flash. But before then, the GPS was kind of flaky, it only fixed when it wanted to. The second one (i traded up at the verizon store) worked great. Instant lock - less than 10 seconds. And i was using the same custom ROM as I was on the first one (not the experimental ROM, of course.) Now I'm on my third one. AND -- I still have my second one, just without a number on it.

I CAN PUT BOTH OF THEM SIDE BY SIDE

The one that always got an immediate fix still does. The one I have now takes minutes, if it EVER GETS A FIX. Doesn't matter if i'm inside, outside, moving, standing still, or hopping on one foot.

Some of us may have just gotten shafted on cheap equipment, makes more sense if they're refurb'd like mine are.

Same issues with GPS not working

My hardware version is 0003. Does anyone have a higher version? I got mine late november.

So my GPS rarely works, one night inside I was trying and trying to get it to work, soft reset, turn GPS on/off/back on, change all settings. Couldn't get it to work for the life of me, then all of a sudden it started to work.

At that point I don't know what I did to get it to work, so I tried to get it tro fail. I was inside, it was raining outside, and I was getting a lock on 6+ sats (massachusetts). I did a soft reset, played with all the setting in GPSViewer, cold start, etc....nothing I did would get it to fail. It would lock in seconds. Power off, or let it go into standby, still all worked.

The next day, it wouldn't work. Again I tried everything, then it finally started to work after an hour of so, and again I couldn't get it to fail.

It is useless if I have to wait that long to use it. In GPSViewer it looks like it is getting sat data, just never gets a fix on the sats.
[Samsung Galaxy S9+ Questions & Answers] IndDoc:
I have the Indian version/ exynos version of the S9 plus, and the screen seems to be overtly warm or yellow throughout. The whites are mildly yellow instead of white.

I tried everything. Changed the screen mode from adaptive to basic to cinema to photos. Still warm. I tried reducing the reds also. Still a bit yellow. Is this a problem with other users as well? Anyone can help me with this? Do I need to send it for replacement?
[Samsung Galaxy S9+ Questions & Answers] th.android:
I've seen a lot of devices in stores (UK) and most of them -but not all- have a cool white temperature.

As with all panels, unfortunately this boils down to a lottery. I'd suggest you try to replace your phone if you're not happy with it and hope for a better white balance on the next one.

My first S9+ had cool whites but uniformity issues (left side cooler than right side) along with black crush. My 2nd unit has good uniformity, cool whites but sadly still black crush.

Actually it might be worth checking the thread about the colour blending https://xdaforums.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385 and see if your device has this problem before you make a decision. If you like watching video on your device, it is a much more serious issue than white balance.
[Samsung Galaxy S9+ Questions & Answers] IndDoc:
Thanks for the suggestion. I went through it and posted it there as well. I don't have the black crush problem (lucky me i guess?), but this yellow tint is unbearable. I think I'll go to the store and show it to them.
