You are showing Sprint as your model and firmware. This is the international section and using anything in here can turn your phone into an expensive paperweight.

Have you tried changing what channel your router is using? If you have too many riders on the same channel or their frequency are grossly over lapping can degrade their signal quality to almost nothing. Changes to one that's not in use and see if that doesn't give you a stronger signal. You can use an app like wifi analyzer to see if they are.

no matter what i download its always paused.... please help. when i restart it pervious download goes thru but if i try to dl something else it says paused again..
try connecting to wifi...sometimes that helps. or reboot your phone. this could be caused by a market overload or your data reception might not be strong enough in the location you are in.

Problem with wifi

Hi, I've searched the forum but have not found a solution hence my post.
I've been using the Nexus S since december and the wifi has been working fine. Normally when you switch the wifi on and it connects to a network the "E" edge symbol goes off and the wifi symbol becomes green and all works well.
Recently this has stopped happening. When I switch the wifi on it connects to the network but the wifi symbol on the top status bar remains grey and the "E" remains and i'm not able to use the internet at all.
The only way to get the wifi to work is to manually switch data off.
I'd appreciate if someone could help with this.
thanks,
Sid
im sort of having a similar situation i think since the update, my 3g icon stays and wifi icon shows no signal but i'm still connected on wifi
This might not help with your issue but do you have the Wi-Fi sleepy policy set to never?
Is anything wrong with your router?

It controls when your wifi goes to sleep. By default it shuts down wifi when your screen goes off. To prevent that you need to change it to never.

3G works like on-demand

Hi All,
I have been having problems with my S3 for some time now.
HSDPA. Sometimes it works and sometimes it does not. It works as if it was set up to work on demand.
Where could it be set up like that? I have checked every menu and cannot find anything.
Help much appreciated.
I don't understand, do you mean it keeps switching between 3g and H when you ate using it and not using it?

HSDPA works and in a few seconds stops. No data at all. Then HSDPA works again for a few seconds and so on. No pattern or anything. I tried to keep it running by keeping Skype work, but it would disconnect from data completely again. It is connected to HSDPA network and I can make calls over that, but no data.
Sounds like your being ping-pong'ed between antennas.
Usually flashing a eastern modem (I can recommend the ZN... ones) should fix it since they are optimized for large cities which have this issue.
Also, having a proxy server configured in the APN settings may cause this issue if it's overloaded and causes connection resets.
If you have one configured, write down the settings(in case you need it ) and try removing it.

Some good ideas.
Heading to the modem collection thread.
No proxy in APN.
An interesting thing is, that I went to another city a few hundred km away and everything was ok, so I thought it was the phone and it started working again. I am back in my area and it is happening again. The only thing is, no one else is having these porblems, even people using S3.
EDIT:Just fashed ZNLH3 using CWM and will start testing. Right after starting the phone, there is no data active.
EDIT2: I forgot to mention, that when I switch to GSM only mode, EDGE works just fin, no disconnects at all.
Try fast dormancy apps from play store and disable it.
The switching between hsdp and 3g is not a problem. It is a technology to preserve your data usage when you are not using.

There is no problem switching between 3g and H, there is a problem with switching between HSDPA and NOTHING.
ZN modems did not work.
Will try fast dormancy, the setting was not available in the ZN modem under *#9900#. Will try LH1 and Pay Store.
EDIT: FD switch installed and FD disabled. Will do some testing and report back. Working on LH1 modem now.
If you still have suggestions, they are more than welcome.

I am having exactly the same problem on 3UK... the data connection just stops working for no apparent reason
For another test, download a terminal emulator app from play store and then ping google.com or any other site in a loop ... See if you get breaks ...
Keep phone still ... Then try same with moving it around your house ...

Must be something with the phone, as I disabled FD and data connecition is gone again.
My problem is that my data does not work when on 3G but it works when on H+.

Position has not effect, it happens wherever I am.
I will try with ping and see.
EDIT: PIng seems to make the connection persist. Will keep it running and see.
Been running ping for over an hour now and no data cutoffs. Means there is something that keeps disconnecting me.
How do I find out what and fix that?
To answer my own question:
I instaled DLI1 last night and so far in almost an hour not a single data blackout!
I was wrong blackouts still happen
Using DLI1 and FD switch, it now works much better, but there are still blackouts.
I will look for the GSM Monitor software and see if that can help me identify the problem..
problem is your location ur phone is jumping between 2 bad signals/towers and one of those towers does not have 3g on it only 2g
I say this because I have same problem at home. certain areas of house amazing 3g reception others .ir does not work and ye so .ir flicks between them and I often eexperience "blackout" . .signal says on H but no data throughput.
try downloading gsm monitor from play store will show u how string signal is and which tower it .
hope this helps
really hope u find a fix ( I've just accepted it )

I'm pretty sure that disabling fast dormancy will fix this. I've seen people with that problem before and was fixed instantly. Search the forum for the fix. There is a file you download to insert that will fix it.

FD is disabled and it is still happening.
Did you try enabling wcdma only mode? Settings-more settings-mobile networks-network mode.
That might work by forcing it to stay on 3g/h+

Of course, I have had it set up like that since the beginning.
Remember that my problem is not with constant switching between HSDPA and EDGe, but with switching from HSDPA to nothing.

[LOOKING FOR A FIX] DATA drops

Hi guys. I've looked around and it seems that data drops are fairly common as of lately. I would like to find out what exactly the problem is.
Here's my situation. Data drops first occurred about a week ago, I was running RBJ and Harsh kernel with hsic fix in. Mainly it happens when exiting wifi range. Went back to nandroid with RBJ/Bricked and it was fine. Tried harsh again issue reappeared. Tried flashing pre hsic kernels and problem persisted. Full wipe, dirty flashes, different kernels etc. Problem is still there intermittently. Now I'm running stock everything and it seems ok for now, but I did experience it once. I guess more testing is needed. I'd think it could be carrier issues, especially as Orange UK confirmed they are having problems at (that would include T-Mobile) but my wife is on the same carrier and doesn't seem to have this problem.
So what you say? What rom/kernel combo you had issue on and on which one you didn't? Can anyone see a pattern?
Problem first appeared:
RBJ
HARSH
Orange UK
West London
As suggested per _ICE_
Post these please.
Hardware: rev_x (10 or 11) <-- go to boot loader to check
ROM:
Kernel:
Network:
Location: City, Country
Description: One of the below or other
1. There is 3g or H sign above signal bar but the tiny arrow pointing up is constantly showing and you can't get access to internet ?
2. There is no 3g or H sign above signal bar but you have blue signal bars ?
3. No 3g or H, grey signal bars and all of the sudden signal bars dias appear and reappear
What do you mean by no data?

no1 and greyed out icon (no connection to google servers which atomatically mean no connection). The rest exactly as you described in that line.
Simply everyone put the same commits in their kernels and therefore caused them all to fail. Those HSIC fix broke other stuff too which is why everyone was reporting the samething. They've been reverted in CM and Franco and other kernels.

I'd agree that it was the case if it didn't keep happening after going back to complete stock via flashing images.
I wonder if something happened to sim along the way?

I doubt it is a sim issue. I get the same thing when I am in different areas of my house. Living room is great but the master bedroom and media room give me data drops. Have you tested to see if maybe this is the same thing happening to you? Certain areas causing it?
My phone will have full bars and show the H but out of nowhere I see the data drop, buts its only in certain areas. It has never happened in the living room where I spend most of my time. Oh and I am not on WiFi because I disconnected Time Warners crappy service and am waiting for Verizon to come set up if anyone is wondering why I was using data instead of Wifi .

Same issue here, it's driving me nuts.
The problem is, I have full service and with a data connection with a H.
Whenever I use an app or anything that would use the data connection, it wouldn't work. It just won't work. It does this, sometimes and sometimes in certain areas.
Say I have full service with a strong data connection, I'll use instagram and refresh, the arrows for data connection won't be there and nothing will show.
It does this constantly. I'm running the stock rom with Franco's r23 kernel. It's been doing this with the stock kernel as well. Using T-Mobile in NYC
It's quite annoying, and I really don't want to wipe and or flash another rom as it happens once in a while.

I only noticed the data drop issue recently, but that might be because I'm on wifi the vast majority of the time. Undercover - I'm experiencing basically the same issue as you are, however my data signal seems to reconnect itself after about 15-20 seconds.
Running stock rooted ROM, motley kernel here, UVed quite a bit, though I don't know if that would cause any problems. Will try changing some APN settings tomorrow and see what happens
When having been connected to wifi overnight and leaving the wifi area, the phone does not switch over to mobile data. The signal bars stay grey.
I have to toggle airplane mode, and then it connects fine. Another fix is to search for provider and reconnect to the network (takes longer obviously)
Is this the same bug?

had this problem on my htc desire and now i have it on my n4
but it occured since 4.0
I seem to have problem with both data and also wifi.
Right now I am looking at my phone connected to wifi and its all grayed out and streaming music stopped. It seems that problem is worse when I have same time connected to bluetooth.
Something is seriously wrong with the new Android.l
No problems here. I'm on T-Mobile if that helps. Cm10.1 and Franco r28.

I get dropped/inconsistent signals as well but only in certain areas of my house or certain parts of the city I live in. I'll have a few bars of H and then poof no signal. I can almost predict when I'm going to run in to that little problem because my loading times and such will be all around slower. Even though I should have a fast connection according to my signal bars. During times when I'm experiencing fast download speeds my signal never falters. PS I'm completely stock, not unlocked, not rooted.

Wi-Fi frequently losing internet ?

S7 edge was working perfectly. All play store updates and the Samsung security updates installed.
Now after a few minutes on the internet while using Wi-Fi and the Wi-Fi symbol has an exclamation mark next to it. Internet access stops. Switch Wi-Fi off and on again and I get a few minutes use again.
No other devices have problems on same Wi-Fi, internet works fine on mobile signal.
What the hell is going on ?
