Connection Dropping :(

Hi there
First time poster, shame it has to be a cry for help!!
I've got the touch HD, and I love it, however over the last week or so its started losing its HDSPA and 3G connection and dropping to phone only. At first I thought this maybe network related (T-Mobile), however it seems to do it in all locations.
I'ver noticed when it does it, the data connection slider in the settings tab, is switched to off, and as soon as I flick it back on, it picks up the signal fine (only to lose it again after a random amount of time). I've downloaded Tweak HD and set the internet to always on, however that doesn't make a difference.
I've not installed any custom roms, its the factory build, really hope someone can help
Thank you

Do you see the connection drop while the screen is on or is it after you have put the phone in standby (screen off)?

It seems to be random, I can be halfway through browsing the web and it'll drop or just coming out of standy.
The most common time seems to be when I do a send/receive on the email tab, it shows the 'H' icon then as soon as it starts syncronising, it drops out to radio then I have te re-send to get it to connect again.

I seem to recall the same thing happening to me back when I was using the stock rom. For the first week everything was fine, then the connection would drop when I turned the screen off or even when the phone was on. If you've tried setting the connection to "always on" and that does not fix the problem, then I would next try and download Schaps Advanced Config and enable/disable the different power management settings. I've suggested this to a few others for disconnect problems in standby and it seemed to work.

Data Constantly In Use

So for the second day straight my phone battery has dropped to half in about 4 hours screen off in my pocket... After closing every program and turning off data sync, the 3G connection is still constantly in use. I downloaded a network traffic program to check usage, and to my surprise my phone had downloaded over 60MB in just 1 hour. I restarted the phone and the problem seemed to be fixed, however it's started back up again, even after restarts and switch from airplane mode and back.
I'm already using SwitchPro, I have all sync options turned off already. The problem didn't come up until a few days ago.
I haven't installed any new programs or widgets in the last couple of daysIs anyone else having a similar issue? Have you been able to solve it?

I had the same issue then I flashed Fresh. Now it is working proper. I would suggest flashing a dif ROM or factory reset.

Load aLogcat or Quicksysteminfo , from market and look at your logcat file. The cause will be obvious from there. If the phone is "idle" and the logcat is recording what's doing the data moving, you can then kill it.

Is it me or is the hands free Bluetooth constantly running even when unchecked.Maybe im looking at the log cat wrong but it appears that way

It looks like location services was using all that data. I think anyway, I'm not sure If read the logcat right, but a lot of that information dealt with location stuff. I went to settings, privacy, and disable google services from using my location and the constant 3g seems to have stopped.
Why would it just go ape **** like that after having the phone for 3 weeks?

I just noticed the same problem, turns out it was the people app that was causing it. I killed it and data traffic stopped. You can launch it from the menu and it loads back up and is fine. Just seems to be when it starts by itself when you first boot up the phone.

[TIP] GPS Issues Workaround

Obviously Samsung has no idea how to write proper drivers for Android phones running the QSC6085. I found a workaround that fixes any issues with GPS.
It's completely simple, turn off WiFi and 4G when you're trying to get a lock.
Proof 1: I stood outside in broad daylight with clear skies connected to my home's WiFi network. Using GPS Test, my phone discovered 12 satellites and made 0 connections for 3 minutes. I closed the app, disabled WiFi (used 3G) and I got a lock of 4 satellites within 15 seconds and 6 - 8 after another 15 seconds.
Proof 2: I left my house and went straight from WiFi to 4G. I got in the car and turned on Google Navigation. I set it to my destination and waited for a lock. After a minute I turned off 4G and got a lock within 15 seconds.
THIS PHONE HAS NO MAJOR GPS ISSUES. Obviously these are simple bugs and I have no doubt in my mind that Samsung is aware of these and will fix them in the next update.
Other GPS bugs I've noticed:
No matter how many satellites I have locked on, my accuracy has never gone below 30 meters.
SNR numbers are really low. According to a leaked ROM for the Vibrant, this can be fixed.

K.. I checked your tips..
3g only[Inside Apt] -- floats between 7 and 8 sat and usually 6-7 locks
Wify Only[Inside Apt] -- Solid 9 satalites and 7-8 locks
4G[no wifi] : stopped with 4 sat and 4 locks but I noticed that my 4g likes to sleep

Yes, it seems that when using WiFi, that updated ephemeris data is not being transmitted, however, it's not bulletproof - after a day or so, it'll try to lock, the 3G connection will go dormant, and it'll just sit there...

I have three epics and have been working with *#1472365# settings and testing for about a week.
I am concerned you maybe getting a false positive on repair of the main problem until you confirm, with no resets and further changes to *#1472365# (which reset the cache) that 24 hours later and in a diffident position you do lock most sats Epic sees.
There are a dozen things you can do to flush out the xtra data cache, just none that I have found that persist and to it regularly (ideally with a couple hours at most for ephmeris, and a day o r two for alamanc). Most proper aGPS implementation will also give the device a minute on warm/hot start, and if is seeing and not locking, grab new assistance data from the best source (first choice network, second birds)
I do think sammy is teid itself up in knots with drivers because of the many different agps environments Galaxy S is sold in. It goes way beyond GSM v CDMA, but also even bigger considerations, like agps data source adn methods, and even whether the device is in a unlimited data carier environment (like our epics) or not.
have you done any testing with the xtra settings themselves? seems to me that is where the rubber hits the road?.

The only change I've made with my phone's *#1472365# settings is setting it to Cold Start to save battery. I know in testing builds of the Moment aGPS addresses were set to internal testing ones that didn't work.

No problem with GPS here. I use Navigation and CoPilot and both pick me in seconds. Navigated from the mechanics workshop today just to test it out and worked like a charm. Guess some have it and some don't.

yes me too, and further, with speedtest app, the only way i can get it to lock on a server that is near me is to have wifi on when I start the app, then it locks on my server, otherwise, it has me 1500 miles away as closest server.

No, we all have the same bug and Sprint Device team is trying to get samsung on it.
You just haven't been in a condition where it occurs, whcih is turning on GPS in a different location say 8 hours later absent flushing the cache.
The Epic doesn't properly check the cache for staleness, so everyone who uses GPS will come up on this problem eventually. It is a bug Samsugn has had before.

the reason why I am asking is Epic has in that debug menu are setting to set time for attempts as well as flushing the cache manually. It would be interesting if we could get that going.
the reason I say so is cold start is a good workaround but it will murder GPS TTFF (time to first fix) in non network conditions. It will make it worse than standalone. Literally every time you start it will be a cold start and you will have to wait for almanac, which is 5 to 15 minutes if outside of network coverage. That is what I am seeing with cold workaround. I am still playings with forcing warm
Are you seeing that? with cold stat set, enable airplane mode, restart Epic, restart GPS and see what happens.

This method did not save me today, when after letting my Epic's GPS go unused for > 24 hours I tried to get a lock with WiFi and 4G disabled. Multiple satellites were visible, but only two were used. Gave up and rebooted. After which, almost immediately, I got 8 out of 9.

Yes I think the OP got hit with what hit us in all testing. That is why i am doing careful controlled tests. Since the main issue has to do with failure to consistently and properly remove expired and invalid assistance data cache lots of things may be removing that cache, for example any changes to that cause a reset.
Right now the only consistent way to remove it without user intervention is to go into the debug and set as cold start. The problem with that is it introduces a new problem affecting standalone TTFF, ie once you get outside of data range you will do worse TTFF than dedicated handlheld GPS units that keep almanac in ephemeris.
This problem is akin to some condition where the phone will freeze and not make calls if you don't use it in 24 hours but most people didn't realize there was a time consideration. 90% of the people would be saying there is no bug or that they have a fix.
to test any fix you have to:
get a gps location.
not use GPS for 12 hours or move location significantly.
do not reset or action that inadvertently fushes cache.
test again.
In every case and attempted workaroudn with this test but cold start hack I cannot get a gps fix on any of our three epics.

@aero1,
The complication in my last case is that I was in Cold Start mode. Maybe I just didn't give it enough time.

Cold start set in *#, data connection on, clear sky and no fix within 30 seconds? Please say it isn't so.

That's the setting alright. I think at first I had 4G enabled when I started GPS Test. But the first thing I did was disable it, thus defaulting to 3G, with GPS Test still running.
But it's possible I didn't give it enough time to lock. I was in my car and perhaps too impatient. I may have given up and rebooted after less time than that.
Since then I have left Cold Start set, and have not experienced a no-lock error condition again. But I have rebooted a couple of times for other reasons. When I started my commute home this afternoon and started GPS Test, it was slow to lock but it came around to a full lock in a minute or so.

I've been using the GPS quite a bit this past week. I've had no problems getting a fix except for onces. It was due to the typical bug (find satellites but not connect). I went into the GpsTest shortcut and set it to Hot Start then back to Cold Start. Immediately the GPS started working again.
Switching back and forth clears the GPS cache and fixes this issue. To me, that's the only problem this phone has. As far as I know, this can be an INCREDIBLY EASY fix if anyone can go into the source and put in a way to periodically clear the cache.

WiFi issue - Disables itself

Rooted Samsung S4 MDL ROM OUDhs SWM Touch Recovery v1.0.3.5
This problem may have started about 11 days ago when for the first time my phone ran out of battery on me. (Had used the NAV a lot that day). I'm not sure if it is connected or not. I'm not sure when I first noticed WiFi was turned off. I think it was over the weekend, but who knows.
Problem: When I leave an area where I am connected to WiFi it disables WiFi and will not reconnect anywhere until I turn WiFi back on. When it detects the loss of the WiFi signal it will show the list of Access points it sees. I don't see it that often because usually it is in my pocket. I just watched it once or twice to see what happens as I drove away from work or home. It will go on to AT&T mobile data and stay on it even if I am in an area with a saved WiFi connection (such as home or work). I essentially have to remember to turn on WiFi anytime I get home or to work.
While looking for a problem I found a setting in the WiFi settings section under advanced. The setting is Check for Internet service "Auto switch between Wi-Finetworks and mobile networks" This was unchecked. Last night I checked it. I figured it may have unchecked itself or something when I ran out of battery last week. Well this didn't help. When I got to work this morning I still had to toggle on the WiFi.
Any ideas?
FYI, I am still on stock ROM. Anytime an update comes down it downloads it, if I reboot, it won't install so that is a good thing. I still have root and SU.

The autoswitch would do it. When you turned the auto switch setting back on did you do a full reboot? Sometimes that's the only way some settings will take action properly, even if it doesn't tell you too.

I didn't do a full reboot after changing it last night. i did this morning however after checking which recovery I had for sure... so I guess I'll find out if that took care of it when I leave work in a few hours.

Nexus 6P LTE won't turn off, even in safe mode. PLEASE HELP.

Hey,
I've had my 6P for more than 3 months now, and have experienced no issues - everything used to work fine.
But starting about a week or so ago, my data won't turn off, no matter what I do. The only way I can keep my data off is if I put it on airplane mode, and I can't do this, as I need to call and text. I've checked and unchecked the box a million times, rebooted into safe mode, factory reset my device, and when all else failed, get it replaced. This issue has not gone away, even on my replacement 6P. My data is being pissed away by background usage, and at this point, have to keep my phone on airplane mode all the time, meaning no texting or calling.
I'm on 6.0.1 with the February patch.
I've scoured the internet for solutions, but no one else seems to be experiencing this issue.
Please help me.

a) uninstall the apps that are "pissing away your data" in the background. Not difficult.
b) options - data usage - cellular data. click that off. if that's what you're doing and it keeps turning itself back on, on TWO different deviced it's something YOU are doing/have done to turn it back on. Likely the same garbage app that's draining your data in the background.
what do you have installed

I'll delete an app, and check to see if the issue is gone, and reinstall if it isn't (obviously get rid of it if it's causing the issue). I'll go through all of the non-stock apps and report back.
Thanks for the reply!

I went through every single one of my apps, and none of the apps seem to be causing the problem. Also, the problem remains on safe mode.
What now?

What cell provider do you have?
This is a known issue on project Fi, I've had it for several weeks as well. On Fi, it only does this if on T mobile, not Sprint. Not sure if other providers have the issue. I just received the March security update today and it didn't fix it.
