GPS on Froyo seriously messed up! Can this be fixed?

There are a few threads on the various Froyo releases, their features bugs etc. but nothing that touches on Froyo's GPS issues specifically.
I'd like to know whether anyone has successfully changed the 'look ahead' behavior that all the Froyo firmwares come with so far.
For those who have not experienced, i.e. not YET noticed this 'feature', here is a brief description:
On Froyo the GPS is showing you exactly where you are even while driving at speed. There is no delay whatsoever. All is well while you are going in a straight line.
The problems begin when you either stop abruptly or take a sharp turn. It then takes the GPS up to a few seconds to come to terms with what just happened. I can only assume this is due to some software component 'smoothing' the path by making up positions, i.e. looking ahead.
I uninstalled JPH and JPK. GPS doesn't do me any good when I see myself still driving down the same road after I took a right turn 5 seconds ago. JM8 and a number of other Eclair firmwares do not suffer from this.
Has anyone successfully 'downgraded' the GPS component of Froyo? Is this even possible? Is there a way to disable the 'look ahead'.....somewhere hidden in settings or some hidden menu?

Did you turn on the "Use Sensor Aiding" feature? That's new in Froyo. Try turning that off. It's in the Location menu.

Thanks. I thought I had that disabled. Is this on by default? I'll give that a try next time I load a Froyo firmware....if there was a quick way to nandroid back without an Odin restore, EFS fixup plus all the Voodoo conversions that would be sooner rather than later ;-)

Isn't it meant to aid while walking? I can see that this may be causing when driving.

Well, there is absolutely no reason this option to decrease performance.. At least shouldnt be, unless Samsung screwed something up as usual. (which actually may be the case)
I had mine set to "off" by default. There is next to no difference while driving.

As I said in the OP, I've always had the issue that GPS took seconds to realize that I changed direction or suddenly stopped. I'm just guessing that something that is intended to help stabilize GPS at slow speeds (walking, swimming with the dog, etc.) might cause a similar effect while travelling in a car.

swimming with the dog? I shat bricks ;d
Anyway, yes that right. Since its like phone is calculating from the sensor (compass, g-sensor -> speculating here) reads the approximate direction and pace you are moving at. It *might* be a problem with g-sensor read, becouse I find it quite flaky (using gps testing utilities exposes its terrible lag and low sensitivity)
BTW is it better after disabling it?

Well, there was a guy in another thread who claimed his Galaxy GPS was spot on. To proof that he uploaded a track of his walk with the dog and it clearly went right through the river a couple of times........I thought THAT was hilarious! ;-)
I might flash Froyo once again and play with that setting......still hoping that the Galaxy CAN do acceptable GPS. :-|

i'm mostly happy with the gps software on JPK (compared to JM8 which was already better than "official")
but the lag you're speaking about is killing me. there's waaay too much delay. sure it makes nice recorded tracks, but using it you'll see its crap
going to try my track with aiding stuff off tomorrow although im not sure its going to help

Well i am using JPK and the MOTONAV is running......ok, but i got "GPS LOST SIGNAL" every 10 minutes and the map jump around, after 10 seconds it will find signal again and back on track. anoying.

I borrowed an iphone 4 to test that thing's GPS and compare it to the Galaxy.
I have attached the Horror kml track file. It's no better, if not worse, than the Froyo stuff. I certainly did NOT expect that!
The kml can be viewed with Google earth and other GPS programs.....
And for the record....I did drive ON the road at all times ;-)

There is a new trend obviously. The more expensive the phone, the more messed up the GPS. LOL
What a total fail for the high-end devices these days.

Maybe they looked at the iPhone and thought it was a great 'feature'.

Oh man, if 2.2 firmware didn't get the GPS issues resolved, then it's pretty much useless for me. I'm happy with the overall phone as it is, minus the GPS issues.

The GPS issues will NEVER be resolved - it's a hardware problem. You probably just won't ever get Samsung to admit it, now they try those lame "sensor aiding" dirty fixes, but that's just another proof that it's a hardware problem - why else would they spend time doing the sensor aiding?
EDIT: I hope Samsung proves me wrong

PROVE IT!!! You are presenting hypothesis as fact, and that might be acceptable in places such as Digg, but it is inappropriate on developer websites.
Also, how do you know that sensor aiding required much much work? After all, it's predictable polling from already working/predictable sensors, unlike GPS sensors which pick up a fuzzy idea of where you are, is affected by satellite coverage, etc.
Sensor aiding can assist even GOOD GPS receivers indoors, tunnels and in areas where signal can drop (heavy trees, huge skyscrapers). Yes, even on Garmin units, this can be handy. We all know that the faster you travel the greater inaccuracies which are incurred, and this can help reduce inaccuracies in those scenarios. There are plenty of reasons to implement this functionality, and not all point towards bad hardware. Samsung probably has a few groups of programmers being thrown at different problems, because programmers aren't scalable, and there is a limit to the number of developers which can work on a specific issue/bug/improvement.

You SAID "The GPS issues will NEVER be resolved - it's a hardware problem", and spreading random rumors like that makes XDA appear unprofessional, and benefits nobody. I've just simply noticed a recent trend towards guesses being slowly changed to fact here in XDA developers, and I'd like to try to reduce the frequency of that happening

Could bad service cause bad battery?

Where I live in usually get a constant 1 bar never really lose service but never really better. I'm at home usually or school and still one bar. But I do always use wifi and don't surf the web on cell data. But could this still cause bad battery?

Yes, if your phone is constantly struggling to maintain a lock on the signal then the battery will drain faster than if it had a strong signal.

You nailed it.

Makes sense thanks. There's nothing I can do really then? Maybe airplane mode at night? And hope for better sevice soon...

Yep... Airplane mode definitely at night.
Certain roms will do well under bad signal.
For me, that is MIUI. I have classes in basements and my apartment complex is off campus in a no-service zone...
MIUI rom has great standby battery life so I can avoid dropping 10-15%/hour during class.

Call sprint and get an Airave for your home then. Tell them you never get service, and your battery dies. They should give you one for free.

Also, if you turn off data, then bad signal doesn't drain the battery as fast. Before I had an airave, which I got the same way as quoted above, I found that by turning off data I would drain my battery A LOT slower vs if I had data on. This was on AOSP so it may be different for Sense...

The answer is yes, because your phone struggles and goes out of its way to find signal, causing more power to be consumed.

[Q] Desire - refusing to wake up after being locked / screen off.

My Desire sometimes refuses to wake up after being locked, it's never switched off or failed whilst using it, only when left alone. I'll press the power button to wake it and get nothing, only way to recover is a battery pull.
I'm running Cyanogen nightlies. So it's Aosp and no overclocking at all. Recently tried the latest crop of Sense roms all the same symptoms. Might only happen twice a day but that's too much.
I've read a few threads on here but never found any great successes, I've ruled out the battery by changing it, and the SD card by changing it (and even not using one).
Would I gleam much from the logging programs? I assumed if it crashed it wouldn't of logged the problem, if you see what I mean..
Any ideas on things to try would be much appreciated. The phone has never been dropped from any height or otherwise damaged.

..I'm assuming that'd fit in with when I switched from Vodafone to GiffGaff and got a new Sim card? Timing seems to fit too.

It was on 'WCDMA prefered'. Changed it to 'GSM only', as I figure O2's 3G signal is poo, well here it is anyway. I'll keep an eye on it and see how we go.

No it's when it switches from HSDPA to 3G to 2G etc... and for some reason it doesn't wake up.. I don't know the details exactly lol.. all I know is it fixes it most of the time lol..

Ah so the phone is at fault, and it just starts doing it one day if you're unlucky?

It's a really grey area for me lol, I haven't looked far enough into it to know for sure. I get the sleep of death in certain locations when I lose signal or it changes from 2G to 3G or whatever (not always).. sometimes I never get it at all, sometimes I do.. It's really strange lol

[Help][50% SOLVED] LTE = random heavy battery drain aka "plummet"

jeffreii said:
UPDATE/CONFIRMED:
The plummet is back.
After 10 days of plummet-free use with LTE disabled, it has returned after less than 48 hours uptime following my re-enabling of LTE.
For me, I am quite convinced that some LTE bug - perhaps with switching back and forth to HSPA+ - is causing the plummet. Unless some very knowledgeable devs join this discussion and help to find the root cause, I only see two options to avoid this problem:
1) Disable LTE and live with HSPA+ speeds
2) Wait for an OTA update with a fix, assuming Samsung/AT&T know about it
Personally I am sick and tired of wasting my time diagnosing this. I have lost time and enjoyment of my device trying to keep a stable testing environment. I now know the general cause and solution and am satisfied with that.
Thanks to anyone and everyone who helped.
Again, here is the link to my method for disabling LTE:
http://forum.xda-developers.com/showthread.php?t=1826409
It's unfortunate that using HSPA+ only also disables 2G, but that's not really a problem for me in Miami.
Click to expand...
Click to collapse
Anyone who can help diagnose the cause of this would be my hero. Please read carefully the evidence I already have.
Scenario:
Battery life is great for awhile and then suddenly it will start plummeting for no good reason. It will continue to do so, even if the screen is off and the phone is unused with all tasks closed. It will not stop dropping fast unless I reboot it. Then battery life returns to normal/excellent..a day or so later it starts dropping fast again.
Things I've tried:
-Factory reset - reinstall only most common apps
-Exchanged the device at AT&T - same result
-Monitored with GSAM (Badass) Battery Monitor and Better Battery Stats. No culprit found.
Important notes:
-As per attached screenshot*, I have tested ways to stop the drain without a reboot. Turning off wifi does nothing. Turning off mobile data does nothing. Turning off the radio (airplane mode) is the only way to stop it - but once I turn airplane mode off, it continues to drop quickly. Only a reboot is a working temporary fix.
-The phone itself is reporting the "cell standby" as the major culprit. I am not sure if this is inflated due to the known bug in reporting that data.
-There is something quirky with the "mobile network signal" bar - I am in Miami where signal is strong almost everywhere. The steep decline occurs even at my apartment where I always have 4 or 5 bars of LTE signal. I am almost never in any area where there is no signal, despite what the line indicates.
Attached screenshots:
1 & 2) good battery life followed by a sudden and steep decline
3) the subsequent "test" listed in note # 1 above with the resulting plateau achieved by turning on airplane mode with the drop continuing when airplane mode was disabled
4 & 5) I then charged the device to full overnight and unplugged it in the morning. I let it sit unused for about 2 hours and the battery dropped 25%.
6 & 7) these screenshots are from normal excellent battery life scenario where the "plummeting" battery did not occur
Thank you so much for any help

Since turning on airplane mode stops it my guess is that its a bad radio. Only option would be to exchange it and tell them this is your second defective unit.

What are the odds of me having two units in a row with the exact same problem, which does not appear to be widespread?
The bad news is that I am past my 30 day exchange window.

If you got that unit during your 30 days you should have 30 days for that unit and if you don't then go through manufactures warranty. Unless your willing to play around with roms to see if that solves it.
In terms of odds maybe your ATT store just got a bad batch either that or you have incredibly bad luck but I do know of one other person who had the same problem if I remember correctly.

My understanding of the return policy, as confirmed by the rep, is that exchanging your device does not reset the 30 days. I would have to go through the manufacturer warranty now, facilitated by AT&T. Much more hassle than just going to the store and swapping it out.
I received my first S III in the mail from AT&T Online. 30 days later I went to one of several local corporate stores and exchanged it. They were definitely not the same batch. This is probably not bad luck and I have heard from several others that they have this same problem...
My next step, after some more logs and troubleshooting, would be to factory wipe again and use the phone stock with no apps for up to a week to see if I can reproduce it. Sounds terrible but I'm willing to do it if it is necessary. Still hoping someone here on XDA can help me pinpoint the problem.
Thanks again for your response.

I get this battery drain maybe once a week, a friend of mine also gets it occasionally, It is very unlikely that our phones are from the same batch, because he got his 2 weeks before i got mine. It seems to be a more widespread problem than we think, and i hope samsung, or someone on XDA, can figure it out and fix it.

Do that and remember to do a test using airplane mode if it doesn't loose battery while in airplane mode then there are two theorys then: samsung software bug that affects radio or hardware issue.
It also depends how many "several others" are, remember even 100 people are a minority compared to the millions of units sold.
Keep us updated so we can get to the root of the problem.

Whats your screen on time, battery stats indicated a deep idle of only 2hrs.
And damn your cell standby % is huge. When I had the cell standby bug it only rose to about 15%.
IMO that high cell standby is not normal even with the bug.

This has happened to me on several ROMs, but it doesn't happen very often. It does seem to be radio related. The last time it happened, I checked the battery graph and the signal strength was solid green from exactly the time the battery started plummeting. Not sure if that means anything but it's another data point.

Strange thing is the bug just reports the % wrong and applying the fix won't actually solve is drainage issues, although if he does apply it and still sees a high percentage its most probably the radio or he could apply it see normal cell % and we be back to square one.

I agree that its gsiff_daemon bug. I get it on occasion when streaming music through web. Even when I close it will drain the battery quickly. Do a search for that daemon and see if that shows up in battery stats. Usually shown as android system. When you hit refresh under battery stats it usually displays the gsiff name quickly.

I noticed the same thing with the mobile network signal bar being solid. I still don't understand why that bar has so many gaps where it appears to show the radio off when it's not...anyways I thought there was a correlation there but have since seen plenty of "plummets" without the solid green mobile network signal bar.

gsiff_daemon is not in my BBS logs...see the new logs I'm about to post.

Ok so I've been continuing my tests from above.
I first charged a bit and then turned off wifi since wlan_rx_wake was a biggie in my BBS log. You can see the log for that period below. Battery continues to plummet as it did before.
I then turned on airplane mode and started a new BBS log. The battery stopped going down. In fact it was one of those situations where the charger mis-reported the actual charge and in nearly two hours time BBS sees the battery as having gone up 1%. That log is also attached.
Also below are screenshots of this whole process where you can see the battery plateau created by airplane mode.
Perhaps we can compare these 3 log files to determine something? I am going to post them in the BBS thread as well.
Thanks again everyone I hope we can get to the bottom of this!

Thanks again for looking. Honestly I am assuming it's a bug deep in the software or something...either that or one of my apps.
First I thought it was an app. Then I thought it was hardware. Now I am just trying to re-evaluate and look at all of the evidence.
Part of me wants to just reboot every night and forget about it...

[Q] Signal Booster

I live in a "dead zone" in a valley. The k3 modem works the best but in my basement there is almost no chance for signal. Is there a script that could be written to boost my signal strength wen necessary? In an ideal world with a toggle. I'm usually charging in this area so battery isn't a concern. I need to study tasker or similar I think for that type of option. Forgive me if that is the wrong idea. I use KT kernel and don't understand all of ktweaker settings and there is so many. I don't know if one will control this option. Ive seen threads about antenna and hardware to install I just didn't know if more power directed toward signal would help. Thanks for any input.

I live in a "dead zone" in a valley. The k3 modem works the best but in my basement there is almost no chance for signal. Is there a script that could be written to boost my signal strength wen necessary? In an ideal world with a toggle. I'm usually charging in this area so battery isn't a concern. I need to study tasker or similar I think for that type of option. Forgive me if that is the wrong idea. I use KT kernel and don't understand all of ktweaker settings and there is so many.

hmmm.. not sure about codes that can boost strength. If there is, please sticky this.. haha
I live in a dead zone as well. There are a few solutions (costing lots of course)
You can look into a device called zboost. Google it and see if its right for you or not.
Hope this helps!

Signal isn't fixed by code. Its fixed by your provider putting up more towers. Only thing you can fix is the signal picture to make it show more bars when you actually have little to no picture. But that would just be a false read and you would still have no signal.
Sent from my SGH-I747 using xda premium

Cell phones are optimized based on how much "power" they can utilize to search for a signal, and how much they should be use after a lock and sustained signal has been established. The more the power phone uses, the more hotter it would become, and the more radiation it would emit.
This is what you see as SAR rating on your phone.
The max power used is normally limited at hardware level too (to the best of my knowledge).
Just giving my 2 cents here

Thanks guys. I was hopeful. Att is the ONLY carrier that will even kinda work. Not like I like I live in the boonies either. Maybe they will add a tower someday. Thanks again.

I had to purchase a 5W booster to fix my issues (my provider paid for it or else i could cancel my contract)
