N1 data connection issue... please help!

Hi everyone, I had a quick question I needed your assistance on.
Sometime I put my N1 into Airplane mode to save battery and when I finally turn airplane mode off I can never seem to get a data connection unless I totally shut off the phone and turn it back on again. Coming out of Airplane mode there will be a 3g signal on the status bar but only the up arrow will light up and anything needing data (browser, market, etc) wont work unless I totally shut off the phone and turn it back on again. Is this happening to you too?
The same thing happens if I open up the Quick Settings app and turn off mobile data (to save battery) and when I turn mobile data back on I have to restart the phone entirely for it to work properly.
It seems like my phone might be having an issue with data connection so I might have to call up HTC about it but I wanted to find out from the other members on the forum if this was happening to them too.
Thank you for your help

It's happened to me before using APNdroid.
Apparently you can fix it by turning the radio on and off in the testing menu (*#*#4636#*#), never tried it though.

~Myn's rls5 4G (issue or not) any one else~

I have now flashed release 5 twice and both times my 4G has stopped working. It will not come on with the drop down toggle and it will not start by using settings. The only way I can get it to work is to use switch-pro widget (I discovered that switch pro would work on accident).
I just want to clarify if I try to turn on 4g with the drop down toggle or in setting my 4g will search like it will come on but than it just turns off. So I decided to try to use switch pro widget and my 4g turned on and worked fine. I have flashed rls5 two times and did a full wipe both times, I did use TI backup to restore I'm wondering if that is causing the issue. I did check 4g with the toggle after flashing the seccond time and it did work.
So immediately after flashing rls5 4g works but something is causing it to stop any one have any ideas? I'm thnking maybe TI backup.

Delete switchpro and then try turning on 4G. It could also help to "clear data" from the switchpro application under the managing applications section.

Thanks MDizzle9, I was having similar issues (albeit completely different ROM). When I took out the SwitchPro (and wiped its settings before I did) my 4g now scans and actually stays on. Working great now!
Mahalo,

Yeah fixed it for me.

Make sure you do a full wipe before installing RLS5. I tried to just install over RLS4 and my 4G did not work. Backup, full wipe, install. Now going to give the removed data governor a try.

If anyone else is having this issue I have verified that by going into "Settings > Manage Applications > SwitchPro" and pressing "Clear Data" the issue is resolved.

Myn's RLS5 4G
My 4G will turn on and scan and even show bars but it doesn't work. It never fully loads. 3G works great. Wifi needs to be shut off and turned back on all the time to work correctly. Is anyone else having the same issues?

My 4G would not turn off unless I turned it off and rebooted two or three times.

Gps?

Hi, I have a rooted eco5 with absoluetly no bloatware. Whenever I use gps it says it cannot find me. Is there anyway to fix that? I've heard of an app that fixes gps, but I don't remember the name. Also I'm sorry for not using the search function, lol

GPS Status?
There is also a mod in the development section that suppose to help fix it.

Thanks for the help. It was gps status.

Yes. Unfortunately the Epic suffers from a few GPS problems under EC05 and we're working on a comprehensive fix for them. However, we're still trying to understand exactly what folks's problems with the GPS are. If you're willing, you could be an incredible help with that.
Has your GPS ever worked prior to EC05? Did it stop working after you upgraded, and hasn't since?
Also, please use GPS Test when testing the GPS as it allows for the easiest understanding of what your current problems are. When using GPS Test, you'll probably want to go into Menu, Settings, and disable the "Keep screen on" option so your screen doesn't shutoff while attempting a fix.
Can you run GPS Test and report what happens? A "good" fix is when the "GPS on" light turns green in 10 seconds or so. A "poor" is when it takes anywhere from 30 seconds to a few minutes to get a fix outdoor in clear skies. "No" fix is when it's unable to get a fix even after 4-5 minutes of good visibility.
If you can report back how GPS Test works, we can debug this a bit further.

I can report on a rooted stock EC05 that GPS has stopped working altogether. Using gps test it never gets a signal. In Maps, the gps icon doesn't even turn on any more. Yes, gps is enabled under settings. This behavior first appeared after I installed Advanced Task Killer and I am not sure if ATK is killing some process that keeps gps from starting. Any ideas or any more info I could provide you to try to help figure it out?

So in GPS Test the "GPS on" light just stays yellow and the GPS icon in the notification bar just blinks? And this is across full reboots (power cycles) too?

It's probably unrelated to ATK. Did it work in EC05 prior to ATK?
We've identified a few issues with the GPS in EC05, one of which is that the GPS can crash and programs are no longer able to use it, but it recovers again after a full power cycle.
What we haven't been able to identify yet are the exact causes of why the GPS doesn't work at all for some folks. Mostly since everyone who has posted in the development thread now have working GPSes, so we no longer can get solid debugging info on them.

Yes, definitely. Are you familiar with running adb commands?
If you can, what would be really helpful would be to enable "USB debugging" on your phone, and reboot (full power cycle) it. Then, as soon as the phone is booted (network is up and it's done "Preparing external SD card"), plug in the USB cable and run on your computer in a command line:
Code:
adb shell "logcat -v time > /sdcard/logcat.txt"
That command shouldn't return immediately, which is what we want. Wait a few seconds, then run GPS Test and wait about 30 seconds or so. Then close GPS Test, and do a Control-C in the "adb shell" terminal which stops the logcat.
Finally, pull "logcat.txt" off your SD card and either attach it here, host it, or email it to me, I'll PM you the details.
Sorry it's a bit complicated, but that's the only way we've been able to get all the necessary information on what the GPS does from boot through a first fix attempt. If you have any questions about running that, feel free to ask.
Thanks!

Hi Mkasick,
so I just rebooted, and fortunately (or unfortunately) gps works. This is how it seems to go for me. It will work for a while on a fresh reboot, but after a while (maybe a day or half day) it fails to start again. When it doesn't work, the gps test behavior you describe is exactly right - icon says "on" and icon light stays yellow. So I assume the ADB logcat file is not meaningful to you if it works right now, correct?
I should also say that from time to time, toggling other radios using the drop down menu from the status bar also fails to work. Wifi specifically will fail to toggle on. Again, this usually happens after the phone is on for a day or so. Glad to hear that ATK is not the likely culprit because installing it has really improved my battery life a lot.
Let me know what I can do to help. You are awesome for working to make this phone better for the rest of us who don't have any coding skills. Should I get that logcat file the next time I notice the gps won't start?

OK, there's a few different issues that can cause that.
One is that the GPS will randomly crash upon exiting or switching away from a GPS-utilizing app, roughly every 1 in 20 times. When it does, the GPS no longer responds to any commands and the GPS icon will stay lit even after you close an app. We're finishing a workaround for this and I'll post it in the next day or two.
The other issue is that the GPS's ephemeris data appears to go stale earlier than it should. Here the GPS appears to work normally, with regard to icons blinking and such, it just can't use any satellites it finds for a few minutes, but if you're outside on a clear day it will eventually fix again. The existing workaround may address this. If you find the GPS won't fix, you can toggle the GPS icon outside of an app and that will download new assistance data which should hopefully help.

Probably not. Actually it might be hard to debug the GPS issues further until I get the crash workaround posted. In the meantime, you can at least discern if the problem is the crash by installing CatLog, and after the GPS demonstrates issues, open the CatLog and look for a line that says:
Code:
E/libgps (####): RIL Request: ERROR 1 (n=110, r=0)
The "n=110" is in particular a good indication of a GPS crash.

I've seen this on occasion too, but not frequently. I haven't had a chance to look into this issue further. It's possible ATK could be responsible here.
Mind running a few days with ATK off just to see if those issues continue to persist?

Thanks! At this point, I'm not sure a logcat will show anything new as long as your GPS does work after reboot. Probably the most useful thing would be to report if the existing workaround helps when your GPS stops working, as long as it's not due to a crash (which CatLog can verify).
I'll try to get that second workaround posted soon. This GPS crashing is annoying and hinders the debugging of other GPS issues.

So neither of the types of crash you describe really apply to what is happening to me. After my gps fails, the icon never comes on. Under the settings menu it says it is enabled, but no application ever gets the icon to come up and there is never any kind of message saying gps signal is lost or unavailable or anything like that. I will try to do what you say with regards to CatLog and send you whatever files seem relevant. ATK will be turned off.
Thanks again!

That could be a crash. If the icon is on when it crashes, it will likely stay on until "Use GPS satellites" is toggled, at which point it will turn off and stay off. If the icon is off when it crashes, then it never comes on again.
The status of the icon doesn't matter as much as the GPS is utterly unresponsive as far as the phone is concerned.

I've just posted the crash workaround. Feel free to flash it (gps_request_sync-EC05.zip in that thread). It's been tested on stock EC05 and SRF 1.1.0, althugh I think it should work on any EC05 ROM.
That alone may resolve your issues, if not, also try the assistance workaround in the same thread and we can go from there.

My GPS was working perfectly for months using the forced cold start. It has had the problem since the update to Froyo.
I tried this one and it is a "fail" as doesn't work at all after a couple of days.

It seems to work at first but I think the "fix" has to do with rebooting the phone, as after a couple of days of uptime the problem of the Epic not using satellites that it sees returns.
I am now trying this one:

My GPS randomly gets no lock without a reboot. This has happened after EC05 update. Now have Bonsai 4.0.1 and Genocide 1.0 kernel. This fix should resolve that right?

wifi wont turn on

rooted, otherwise stock 1.83 atrix (not unlocked)
Just spent a few hours getting my new phone all set up. When I was done I turned wifi off to see how fast mobile data was here. Now wifi won't turn back on.
When you turn it on, it sits at turning on for a few seconds, then shows scanning for a few, then wifi turns back off.
None of the usual tricks bring it back. On older android phones, deleting wpa_supplicant.conf would usually clear this up, but that didn't help either.
Just gave up and did a factory reset, even in the setup wizard wifi wont turn on. :/

Now that is crappy as hell.
SBF it with the 1.83 on the forums, and then try everything once more. If the wifi still flips out on you, warranty it.

[Q] GPS problem

Looked to the best of my searching abilities, and prob just missed something. However, is anyone else having a problem with the GPS? In particular, when I start an app, any app, that requires GPS, I have to turn the already on GPS off, then back on. Otherwise, even though its marked as on, the apps will say 'searching for gps'. Now, after I turn it off then back on, the apps immediately get a lock and operate as normal. I didn't spend much time with the phone before rooting it and have no idea if the problem existed before hand. Maybe I have a faulty phone? Or maybe I should flash back to stock?
If no one else is experiencing this prob, I'm thinking I should return the phone. Just need to learn how to revert back to stock with no one the wiser.
TIA

I've never had that issue. But i used GPS Status to clean the gps data and download more accurate one. It makes the signal stronger I think or we'll at least it seems to grab more accurate readings.
If you download it from the app store. Hit the menu button > tools > Manage A-GPS State > Reset. Then go back in and hit download.

Just tried mine again. Works as it should. I have GPS on all the time and when I go to map or navigation, it instantly shows my location and is ready to navigate.
The issue you are describing was common on my HTC Evo 4G LTE, though. That was pretty much the scenario anytime I wanted to use the GPS apps.

I use them on all my phones. It may connect good but I noticed on like navigation app it would bounce from spot to spot I was driving to. But when I use that gps status it smooths it out for me so it's smooth and moves as I do.

Found the program and tried what you suggested. However, I again had to turn the gps off then back on for even that app to work. I am going to figure out how to flash back to stock and try it again, then decide if i need to return the phone.
Thanks for you suggestions.

some of this could depend on the area you are in. downtown with skyscrapers = less accurate gps. Or at least in my experience. No matter what phone I have had.

Just a quick update:
Figured I had nothing to lose by trying one of the new roms that are out before I returned it. After flashing I went back to test the apps and they now work without a hitch. So, seems there was simply a software glitch preventing apps from seeing that the gps was already on and ready. I'm just relieved not to have to go through the extra steps to get navigation up and running!
Thanks again for the responses. Saved me a trip to test another phone! :good:

Glad this worked. what rom did you use? I am on uscc and have the same gps issue where you need to toggle it off then on and instant lock. Maybe we can extract the gps part and make a zip that updates just that part.

Exactly same issue with stock rom

I have exactly the same issue with the stock rom of my Galaxy S4 (i9505). Mine is not rooted, just standard. After having tried many things, I found the same workaround to switch off and on the GPS to have the navigation software working. This issue occurs with all software making use of the GPS signal.

i just unrooted my phone back to stock MDC did a factory reset.. rebooted now my GPS wont work.. location error.. failed location current location? i tried everything turn data on off.. wifi on off.. reboot ect..?? please help.. thanks

Sorry, never saw the responses posted and figured my situation was isolated:
Problem resurfaced even on new rom, so returned to the store for a replacement, no problems since.

Solution found
I found the culprit: After uninstalling Yahoo Weather, the GPS works just fine!!
