[Q] Data network switching

Has any one tried manual data network switching (i.e. from hspda to edge)? Does it save battery life? Is there an automated app for this (like when the screen is off).

Try juice defender APP, it will stop your data when your screen is off.

But, some times, when screen is on, it takes time to get the data network. it happens occassionally, i dont know why it happens.
Any one has idea?

2G/EDGE increases battery life by about 60%, esp noticeable in calls.

Any idea what's causing this

It's like my radio sleeps sometimes. This screen shot shows no data. Once I wake my phone data reconnects. I don't think this is caused by no signal.

Looks like you live in a so so signal area, the closer it is to green then the greater your signal is. I would think that's an issue with the towers in your area cuz as you know the signal fluctuates often even while sleep.

Thanks. I don't understand why it shows no signal when there was signal. As soon as I woke the phone it reconnected to the tower. There's a delay when it switches from 4g, 3g and 1x....This long area of red was probably the phone stuck in the delay between switching? While trying to submit this post I just lost data in a strong 4G area..... I don't get it.

How often within a day/week does this occur? That's still odd behavior that you lose signal or notice signal degradation while sleeping.
Sent from my SCH-I535 using xda app-developers app

This happens once or twice per day. Seems to happen in areas with less than great signal, that's why I think it is maybe getting stuck in the transition between 3g and 1x. No idea why it stays stuck once I move to an area with better signal.... Seems like the radio is sleeping until I wake the device.

It happened to me before. Try to go to flight/airplane mode and back. It should reset everything. I also sometimes press and hold the home button , then remove all applications and go to ram memory and clear it.

That does work but we should not have to do that in the first place. Hopefully a update will fix the data problems.

Are you stock? if no, what ROM are you running? Are you rooted? what apps are installed.
If you have CWM recovery, i would try to wipe cache and reboot, see if it helps at all?? if you don't have much installed, i would say do a full system restore...

one other thing, are you losing data, ie; not getting text and or phone calls? Also, check to see if you have any battery savers checked. Might be just a method of saving battery by shutting off data until it is needed.

I am on stock not even rooted. Phone is a week and a half old.... I am willing to wipe data if you think it would help.

As far as I know I am not missing phone calls or texts. Power saver is turned off. I am basically running the phone the way it came brand new (not many apps, no root, no unlock.... Yet).
Thanks for the replies. Any chance a factory reset would help? My mute/vibrate functions in settings do not mute the phone either... Still get audible notifications and phone rings like normal. Unrelated to the data issue but still weird for a new stock phone.

I'm not going to lie. I don't know if it will help or not. But if you are stock and got nothing to lose it would give it a shot. Can't hurt? Also, as others have said, it sounds ds like it could be because of signal strength. A lot of variables though.

Data wipe did not fix the mute problem. I am very annoyed. Will see how my radio acts today after the wipe.

Just found a post on Verizon's forum regarding this problem. Apparently I was right when I said there was a issue when switching from 4g/3g/1x.

Now before I say this I want to make it clear that I am not representing Verizon or Samsung in any way with this post, I am just updating the users on what I have identified from the test of my device on this reported issue.... So with that said you can take this accordingly..
Ok everyone about the reported connection issues reported, I recently have been able to duplicate the signaling issue reported on my S3 and it appears to be miner for me at the moment but I can say that it is present.. I recently attempted to isolate the bug and I learned that when I placed it in my test rig to monitor the device in the weakest area in my house the software would temporarily powers down the radio for a few seconds that causes the device to loose all connections (Wifi, Bluetooth, 4G and some times also the network connection), this only happens in a weak connection area and it does appear it could be a software related bug with how the radio drivers handles switching the connection from one connection to another.
From the test results this does not appear to be a hardware issue but I do agree that this could be a pain for a user on the border of a 3G and 4G connection because any connection change causes a crash or radio and force restart.
I have reported this to CS and it appears to be a situation that is being looked into and a solution is possibly in the works... Eventho this isnt a major issue for me at this time, I hope to see a update to address this soon.

check any settings you may have done in the "Profiles" option? is that on a option in settings on the stock rom, lol, cant really remember

What a joke. This really irritates me.
Sent from my SCH-I535 using xda premium

This is frustrating. I have lost signal now two times and needed a reboot to get it back. When I did, I was not only losing data, but phone also. I would get this barrage of texts and missed calls.
I am rooted and unlocked, so there in itself could lie a problem, but it comes without warning and the phone appears to be working. Would the SIM card really effect that?

Crazy Battery, can't figure out why.

So usually on a work day, my phone will sit in my car for 13 hours without being touched. By the end of the day when I go to bed, I'll be around 80% to 83% battery.
Today I noticed a couple hours after I got hoe that I was at 31%. For the record, this is a Maxx. I have two different wakelock detectors installed on my phone but I can't find anything that indicates what went haywire today. The Battery section in Settings just says it was "Android OS".
Here are some screenshots of the screens. Do any of you see anything I'm not? I have no idea what the culprit was.

Could point to poor cell service reception but it sounds like the phone was in the same place as other days.

Maybe you could try airplane mode if you notice it happening again ?

Yeah, same place it always sits at when I'm at work.

My battery life has been no where near as good as it was my first few days as well.

Reboot it. Something is stuck on.

Downloading Update

So is google having server issues? I have just gotten my new N5 and during the initial setup, the first thing it asks after WiFi is to update the OS. There is no way that I can see to skip this step. But it is just sitting there. There is no download progress bar showing me how the download is going. It's been there a while. I have no idea if it's ever going to finish. I have very fast WIFI which is working fine(i can use it on my nexus 7 right now) and 125mbs should have been just a minute or 2. It's been half an hour. Can anyone at least confirm if there is a progress bar on the download? If there is and it's not moving I will at least know for sure it is not working(as opposed to working veeeeery slowly).

Pretty sure there was a progress bar when it updated. It just went so fast I didn't even notice. Dead shouldn't take longer than a minute. Let's hope someone can chime in with me and ask you to go ahead and reboot device to see if it helps.

I tried rebooting, didn't help.

Maybe try on a different internet connection?

Sorry dude. I got nothing else. Unless you wanna boot it up without enabling WiFi and see what it does...

Well I still don't know what happened, but it just worked suddenly. I glanced over and it was rebooting. Don't know maybe it really just took over an hour to download. Odd.

Great that it worked out, finally.

It took my buddy 2.5 hours to download the update and took my an hour. So there is something funky with their servers. Also, Google somehow screwed up the wifi web login screen so that the browser remains blank forever.

Hi, I'm having this issue too. It looks like the download doesn't progress. I already tried to reboot the phone and to connect on 2 different wifi networks.

Problem solved as reported here

New 4.3 issues?

I know there are other threads but you have to read 40 Verizon bashing posts to actually find a post that's relevant to actual issues. I'm completely stock and not a fan of the update. Here are my issues :
Lag, lag, lag.... Huge Ram hog. It uses almost all the ram with only my texts open.
Random flashes from the camera's flash. No rhyme or reason.
Phone doesn't make call when picking up in a text.
Widgets on lock screen (texts) locks up when you click on them.
Anyone else having issues? Anything I need to look out for? Any fixes?

You can have posted this question in this thread http://forum.xda-developers.com/showthread.php?t=2575661
And someone would answer you.
As for the camera flash, look in your settings. I remember seeing it in the phone settings somewhere that that you can turn camera flash on for notifications.

No problem. I don't know about the lag fix. Mine lags worst when unlocking the screen.

I have no shortcuts on my lock screen and have no lag?

You don't have widgets? Texts to pop up on your lock screen?
One more thing that sucks... Battery. Less than an hour screen time and no videos, music, or games.
