Samsung Moment :: Lost Network Connection
Dec 7, 2009
After reading the forums and changing settings and doing a few battery cycles, I had been getting really good battery life of at least two days on medium usage and 3 days on light with my connection not having any real issues. Then, 2 days ago I installed weatherbug and beautiful widgets. While I enjoy both, it seems like my network connection goes down fairly often now and I need to turn on wifi to check email or do anything else web related. Has anyone else lost their network connection and been able to narrow down the cause? I'm hoping it's not one of these two, but I can't imagine what else it would be.

I am checking to see if my app has a network connection Whenever I rotate my screen between landscape and portrait this method returns false. It makes me wonder if Network connections are getting killed during the rotation?

I'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.
The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.
The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.
When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.
When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.
Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.
Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.
Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.

If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.

I was running the JI6 2.2 with cognition beta5.5 and was attempting to update however I needed to swap kernels since the current kernel didn't verify signatures. I was using vmware on a mac and i started it but then continued to use the mac side however the computer disconnected the phone from the windows side and now it is stuck showing an image of a phone next to a computer with a triangle with a ! in it between the two. Pressing all hardware buttons does nothing but black the screen and go back to the same screen. I've taken out the battery, sim, unplugged the cord, everything. Can't get back into download mode to redo the kernal swap. It's definitely connected to a valid, and working, usb port and i am now on windows itself instead of vmware. What do I do?

I have lost every thing on my sd card music, pistures, ringtones, all of it. I'm not sure what did it but the last message I got was there was too many songs on it and that is not true. It's an 8gb card with 700+ songs 15 pics and 4 ringtones so it being full is bs. I don't know what killed it but I suspect Ringdroid or 91Pandhome both have been acting funny for a couple of days force closing alot. Anyone else have this happen to them and is there a way to recover the data on the card as my laptop just does not see it anymore.

On my bus commute to work, using my 2.1 Samsung Moment, I pass through some areas with less than ideal connectivity. Sometimes when I'm accessing a news app, an exclamation point appears and I lose all connectivity. I usually have to restart the phone to regain connectivity. Is there any other way to regain web access other than restarting the phone?

My parents just recently bought their first smartphones. They both have Samsung Moments now and think the phone looks promising, but they've already ran into their first quirk. I searched for a good halfhour to see if I could find an answer to their problem but I couldn't find anything. So without further adieu.their problem. They had older phones that used simcards. The sprint store loaded all of their contacts onto the moment and all was peachy. As soon as they went onto the market they had to establish a GMail account to be able to use the market. Once the GMail account was established all of their contacts were wiped. We can't find them anywhere. If anyone has had this problem or would possibly know how to locate the contacts it would be greatly appreciated if you could post the steps to do such a thing. Also if there is anyway to put a simcard onto a computer and transfer it to a phone they still have their cards and I could try to do that.

Going overseas in a few weeks mainly for sightseeing. I'm not worried about using my phone (I know it won't work on the networks there) but was wondering if the Moment would be good device to take for checking email and Internet in those spots I can get a wifi connection? Will it even work? or should i take my laptop?

Okay this is starting to irk me, i've been trying to teather using PDA net through my stock USB cable, i plug in the cable the phone and computer reconize eachother i mount the cable through the notification bar, start PDA net, everything works great, i start watching a show on fox.com and get 15-20 minutes in when i get the usb device being disconnected tone, look over at the phone and it says preparing SD card as if i had unmounted it, if i try to unplug the usb and plug it back in it charges but i never get the notification to mount the cable again. I have to power off the phone and power back on to fix this. WTH is going on here, i know a lot of people were having issues getting the usb connection going but that appears to be fixed by removing and reseating the sd card, which i have done many times. I will have a perfect connection with the laptop and phone sitting still on a table when i randomly lose the connection and have to reset the phone.

Moment keeps losing evdo. Then the browser will timeout on all web pages. Email will not send or receive. Sometimes when this happens, I cannot text, or make a call. When it happens you can only see the up arrow on the left. Sprint store swapped it out for another Moment, and it did it in their parking lot. A few times after this happens I have to do a hard reset to get my email working again. Typing is slowing down on here as well.

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I keep having this problem with my Moment where it will refuse to do data connections. Sometimes rebooting helps, sometimes it doesn't. It happened three times today, and I was ready to throw my phone out the car window. It's happened on and off since I got the phone 2 months ago. I hoped it would go away after I updated to 2.1, but no dice. My wife, who doesn't use the phone as heavily, doesn't have these problems. Some days (like today) it seems worse than others. I see scattered forum posts about "evdo lockup" and "cdma lockup", but no real idea of how to diagnose what the problem is, and more importantly, whether it's worth taking it back to Sprint and trying to get them to do somethin.

Does anyone know how to completely disable the mobile network on the Moment? I need to so I can use it for my Battle.net mobile authenticator while I am using my fiance's new Samsung Reclaim for a month (to get the upgrade price on it) and she has my Hero. Basically, anytime I need data on it, I want to use WiFi but if I leave it on it can and will probably mess up calls on the Hero. My Hero has a nice little check box to disable the mobile network, but the Moment doesn't.

anyone else having this problem? using 2.1 under caulkin's kernel. it seems like I can kind of overload the phone doing too much and the mobile network connection on my phone will disappear completely. this is while downloading something that may download too fast, sometimes it happens loading .GIF images too. I'll have to restart the phone to get the internet back. this happens no matter if I'm using wireless, USB or bluetooth tethering.

Running 2.1 dd03. I've had a few issues, the worst being-
- Occasional complete data connection loss with no 3g/1x icon (never with 1.5)
- Google voice search works from the soft keyboard but prompts "server problem" from the widget.
- Tower based location puts me 20 miles away from home in the same place all the time (cj05 days are here again).
- Phone turns on by itself when charging and occupationally unlocks and stays on (never in 1.5)
- Phone seems to heat up more and burn battery more rapidly (vs 1.5) when in low or no signal area.
Here's the new one I had this morning. I received a call, but when attempting to answer dropped/lost the call. I went to the call log and re called the number, connecting with the other parties voicemail. After leaving a message, I hung up with the red hard button. After a short time I tried to call again, but the phone wouldn't connect (stayed on dialing). I pressed the red button to cancel the call and then pressed again to turn off the phone. The screen would not turn off. I could navigate the home screen and pull down notifications, so it wasn't locked up, but I couldn't turn off the screen. The red button would quit apps, so its press was registering, but a long press didn't bring up the power off menu. I had to pull the battery to power down. This is a long way from a release OS version. Fix soon.
