[Q]no gps

I'm on olympia rom 1.2 eh06. At first my gps was just crappy, 2 sat lock at best. Now I get 0 locks, I find 10 though, and my gps icon won't show up, although it used to. My gps refuses to turn on. Anyone know of a fix? Or what happend? I mean I'm going to upgrade to eh17 soon and hope its fixed but id still like to see any insight into this. Thanks!

Try reflashing, try Odin back to stock confirm it works and flash again, try clearing GPS Agps with GPSstatus from the market, try ##gpsclrx# but you have to have your MSL number handy, get it from connectbot>local>Epic and type getprop ril.MSL in the box. Caps are important. Or as a last resort try the EFS clear noobnl suggested but it requires going through hands free activation.
I used the gpsclrx.

Ill try these options out, thanks!

Just to add, from my experience all samsung phones have a problem with gps lock.
i910, had bad reception took for ever
galaxy s 4g, never had a lock ever. I would carry a shift around just for gps.
Epic 4g, at first it was hard. Then after rooting its just unusually good for samsung.
Nexus S 4g, this thing has trouble picking up wifi let alone gps.

SOLVED[Q]Wifi continuously scans even though connected

I am on Legendary 2.1 and just had it pointed out and I verified that even though my wifi is connected to my router it continuously scans every few seconds. This has got to be a battery drain. Is there a way to turn off the scanner when connected or set it for every 5 minutes instead? Thanks.
Edit: Thanks TeamERA for explaining that it only does that while in the listing window so it can update the list immediately. It defaults to the scan interval in build.prop when that window is closed. Thank you.

I think romtoolbox allows you to change that Im not sure but you can check it out.

Sorry root tools by jrummy allows you to change wifi scan intervals

I'm pretty sure you should be able to turn off 'network notification' while connected...this should stop scans since this option is made to notify when a network is available. In theory, if its not notifying you if new networks are available, I would assume it's not scanning. Good luck

I tried SleeperROM and it does it there too. Can someone look into making the scanner manual only?

That would be awesome cuz you have to figure that's a lil bit of a battery drain.

I found a program called wifi buddy on the Android market. This program allows you to disable wifi scanning.

I will try that...thank you! Probably add hours onto my battery life on weekends at home with wifi on.

Wifi buddy settings only control that app not the system settings so disabling wifi scanning only worked inside app not to system wifi scanning
Sent from my SPH-D700 using xda premium

I'm not knowledgable enough yet, but has anyone looked into using SQ Editor? Perhaps something can be manipulated in system files to just disable intermittent scanning all together? Only initial scan when wifi is activated? Just an idea...

That's what I was hoping for. Can't seem to get a DEVs attention to look into this. Build prop edit doesn't do anything.

Trying to find any sort of process or folders in root explorer that relate to wifi/scanning and coming up empty...I'm with you Kenny, we need a dev to pick this up, especially if editing build prop showed no results

I think my phone is doing this too.
In betterbatterystats mmc_delayed_work (under kernel wakelocks) accounts for 90% of my wakelocks, this does not happen on 3G so it is definitely related to Wifi.
I thought it had something to do with my router (DIR-655) as other people said they experienced unusual drain with that router.. Not so sure now.

This is probably the main reason people are complaining about their battery life on the gingerbread builds. I think it is more of a EI22 issue. How did EH17 or the previous gingerbread Roms handle this and if it handled this issue better can we take something from to fix our problem.

It would be nice to actually have the system manipulated, however, I am pretty sure that Juice Defender has an option of wifi control...I think (and I don't fully remember, just went to Thunderhawk and haven't put it back, trying to figure out other ways to better battery, as is everyone else) that you can allow JD to stop all wifi unless user selected.

So I don't claim to be a dev, but I just thought of something that might lead you in the right direction. I remember a post about lowering the signal threshold on your phone to get better 4g connectivity a couple of months ago in the general section. Its a dialer code and you need your msl to gain access. This is one of the phone settings like at the bios level. When I did this, I was able to see a boatload of settings that you would not find anywhere in the os settings. If you know where I am talking about and know the dial code to get in there, I do remember seeing some wifi stuff. Maybe something in there you can change scan or retry rates, with signal thresholds that might work for you. Write down all changes you make if u need to go back.
Again, just a thought trying to help.

That's a good idea. I will check that out when I get a chance.

Am I the only one with Wifi sleep issues?

Just about every time my phone deep sleeps, wifi shuts off completely. I've tried multiple roms and kernels, and every advanced wife setting combination possible. Thinking it's a hardware issue in which case bye bye nexus.
I've googled and googled and only really found suggestions like "uncheck wifi optimization" or "make sure turn wifi off while sleeping is (un)checked". Tried all of that, and still persists.
Anyone else have this issue, or can someone give me an out of the box tip?
Thanks

You've probably already tried this, but have you tried a full wipe? Also, have you tried wiping you device's internal memory (SD card), and have you tried reverting to complete stock and starting over?

its a known issue with 4.2.2 roms, nothing much you can do about it, temporarily it can work but problem will repeat itself

I have done a full wipe, but not wiped the sd card, or reverted to stock. Hoping to avoid such a tedious task.
So my options are either suck it up, revert to a 4.1 rom, or get a new phone?
Thanks

Thanks for your suggestion, let me try and report back later to see if this works.
This problem has been constantly bugging me that I want to dump this phone. Seriously disappointed with Google over all these bugs...

but I keep wifi optimization off... should I keep it on?

If you are unlocked, you can flash some custom kernels to fix the problem. I use Fancy Kernel and the developer included a fix in the kernel.

After fiddling with the Wifi Optimisation, I would like to report back that it DOESN'T WORK.

My wifi will NOT TURN ON

So I wanted to flash the new jedi rom on my note2. I was running myrom. Through recovery I wiped the system and then I wiped cached. The usual. I have flashed many roms so I knew what I was doing.
So then I flashed the new jedi rom. And its wasnt working because this kept popping up without even letting me use the phone-> 'android.process.acore has stopped unexpectedly'. And then I was like wth? I flashed back and recovered my previous rom and data and that rom worked just fine again.
So I did some reserch and I came across another forum that claims the fix is to flash SUPERWIPE. So I did so, then I flashed the jedirom again and it was working fine without any popups of any errors.
Then I noticed my wifi would not even turn on at all. I press the botton to turn on, and it says turning on, then it will go back to saying turn on, as if I never tried to turn it on at all. Please help guys as much as u can. Everything else works jist fine on my phone btw.

Its happening to me too. Except for the whole other problems. It happens randomly, not only wifi stays "turning on" my bluetooth doesnt work. This gets fixed over time idky but its really REALLY annoying.

Had that happen on my phone. Wifi and bluetooth wouldn't turn on. It would fix itself sometimes, but as soon as I leave a wifi area, it stops working even if I go to another wifi area. The only fix I know of is to do a warranty exchange. That's what I had to do.

My bluetooth isnt working as well! Wth x [ I need to fix this
Sent from my SGH-T889 using xda app-developers app

It happened to me once before not to long ago and I returned it for an exchange. But a couple weeks ago I flashed a carbon nightly and the WiFi wouldn't toggle on again, flashed a different kernel and presto it was back.

Im not to knowledgeable with kernals in all honesty. Im very comfortable with pretty much anything else tbh. What kernal would you recommend for me? I guess ill try that, hopefully it would work for me

Bad battery drain issuse

My phone has a bad battery drain after switching to cyanogen mod 10.2, I hate stock and don't want to go back. Do any of you have any suggestions on mods or something to save battery? Greatly appereiciated!

I had a very similar issue with Cyanogenmod with the Chomp messaging app installed. Uninstalling it solved my problem. Do you have this installed, by any chance? If you go to Settings --> Battery, what do you see sucking up the most power?

I dont have chomp installed, and its showing my screen is taking most the power. The drain even happens when my screens off so i dunno lol. i may just buy a new battery to see if that helps, thanks for the reply though!

I feel your pain. Ive had this problem since the inititial stock ICS update though, not when i switched to cyanogenmod. Long story short, I tried just about every rom and kernel available to no avail.
Turns out the problem was my phone wouldnt deep sleep for very long, even when idle for hours. I reverted back to stock GB 2.3.6 and that seemed to work. I left my phone idle for about 10 hours (During the night and morning) and it only drained 16%. After calibrating the battery it lasted even longer. I know you hate stock, so heres another possible cause/fix: The process mediaserver seems to be draining plenty of peoples batteries. I found the attached .apk somewhere on XDA and its supposed to kill mediaserver and keep it from restarting. I havent tried this personally but it appears to work for other people.
If the kms app doesnt work, take a quick look and see if your phone isnt liking nap time-- If thats your problem, here is the link for stock GB (Rooted, of course). The download contains Odin and the .tar file you need to flash. Dont worry about wiping your data or anything. Just go into download mode and let odin do its work.
Good luck
--Edit--
Found a great ICS rom based on el29 so it will deep sleep. Called The Blu Kuban, I'll post link when I'm home. Fixed my issues and then some, definitely worth trying. Use the Nova launcher not Apex. Much better.

Did some research and the Virgin Mobile model is virtually identical to sprints so those roms will work. The carrier wont know the difference (and the phone either) so the network should be fine. Let me know if the kms worked and/or if u installed a custom rom.
