Network 3G and H swapping problems...

Hi
I have this problem and i think ive come across a few people with the same frustration.
Which is the constant switching of our galaxy s fone networks frm 3g to H.... Happens so constantly it disrupts and keeps me in limbo so many tyms i cnt even tether properly with this problem!!!!
Please olease is there any fix for this out? Ive looked everywher!!!!! And if not. . . please as a humble request can a dev please create something so that only H frequencies are chosen and are prioritized so that it doesn switch to 3g please?????

Ha.
Yeah mine does too sometimes.
A way I get past it is to tap back button and select again and it quickly loads up in h.

Could be a problem with XXJVS radio? I go back to XXJVR to compare results.

HSDPA is an extension of 3g. It uses the same frequency. The reason it is switching is to save power for better battery life. It switches to H when you are using the connection, but than switches back to plain 3g when it is idle.

I think there's a problem with it. Uhm however I'm on XXJVR modem for now.

I think so too. I'm on odexed jvr and only sometimes it hangs switching between h and 3g.

Mate. What's with your logs obsession????
Too much hassle to log. Hardly ever happens and when it does its an easy fix.

user experience is well problematic
one will see 3g changing to H and call it a bug or so =)
i belive only on what is there in logs

Yes ofcourse its an extension from 3G to H .... But i am still using the dam network n it still keeps changing to 3g and H is there no way to keep it on one of em?

That's just how dataconnection works. .if you want to keep your connection in H-mode constantly, you need to make your phone to ping something for every 3 seconds...like ping -t 3 8.8.8.8 in windows (if I remembered it correctly).
In short: connection is in H-mode as long there is traffic. .

In my experience (from reading stuff here and observing my phone) it seemed that constant switching between H and 3G drains battery faster than if we could force the phone to use only H. From your post, I understand this is not the case. I never thought that 'switching' was a battery save feature...

I'm using CM7, and although it switches to 3G for a short period of time very infrequently, most of the time I have an 'H' displayed, even when it's idle. I also don't notice any significant battery drain. Maybe my phone is just crazy, though.

I've had this since day 1 with my phone, through many different roms... it's frustrating as all hell and really hurts my battery life and my patience

The switching from 3G to H is not the problem and not the cause of the problem here - it's just the symptom.
It's because data is lagging and stalling further upstream, so the phone is simply returning to idle as it should.
The solution is to change carriers to something that gives more reliable data.

Take a look at http://forum.xda-developers.com/showthread.php?t=837716 for a guide to disable HSDPA for better battery life.

Very useful info .... I asked for a solution to stay on H i get a reply to disable to SAVE battery life which is clearly not most the prioritized issue here... But thank u.... Any one else with a solution to either stay on H or 3G????
i had a sony x10 mini pro and problems were similar... But then from control panel i selected 3G only ( only options were 2G and 3G) and when it was onnit it NEVER gave up H ... Constantly stayed onnit so if its possible on a fne **** that m preetty sure we cn do it on a galaxy s

Wouldn't the most likely cause of your phone switching back and forth be because you're losing connection? My phone stays in H when I need it, and leaves it when it doesn't. So...

Nope i have constant network on full bars... Keeps working only until the H starts swapping is the time my phone enters limbo and i lose connectivity

The problem is that it literally hangs between 3g and H changing constantly without loading anything. If I say for example on xda, touch a thread and it does this, it may stay in a changing to and fro for minutes and not load. But if I select thread again as soon as it starts doing it it opens to thread quickly and normal.

Wifi connection problems after using onavo data monitor app

Last week when the Onavo data monitor app appeared prominently placed on the market home screen I gave it a try.
Unfortunately it created a very annoying bug on my phone running JVU and Semaphore 2.5:
whenever my phone looses it's wifi connection for any reason it will not recognize and connect to available wifi anymore even if placed directly near the router with full signal strength!
The only way to get it connected again is switching wifi off and then on again...
I already uninstalled the app and did a factory reset but nothing changed. Probably it messed up some system files that don't get touched during factory reset.
As I'm in vacation now and don't have my data cable with me to flash a fresh firmware, is there any way to resolve this issue in other means?
Sent from my GT-I9000 using Tapatalk

Nobody here with any idea how to resolve this? It's really annoying as even battery consumption goes up very much when the phone looses wifi and auto connects to 3g.
Sent from my GT-I9000 using Tapatalk

I have no idea about your problem. I also have just installed Onavo on JVU firmware for a couple days, but everything is still ok....
So, I'm thinking the cause is from your router!! Why don't you try another wifi network?
Good luck!! ^^
Sent from my GT-I9000 using xda premium

Thanks for your answer! It doesn't depend on my router. As I said I'm in vacation right now and therefor using many different available hotspots, it happens on all of them... :-(
Sent from my GT-I9000 using Tapatalk

Any issues with battery drain and onavo? Cause it was sucking mine dry!! I thought it was semaphore's fault (i'm on icssgs 4.2) until i figure it out and uninstalled it. Now it is Almost as prior installing onavo. I have a feeling that it left some garbage behind though.

It definitely left some garbage behind and this thread is about to find out how to get rid of it.
Battery drain was and unfortunately still is very high on my device thanks to the non desired 3g connection instead of wifi...
Sent from my GT-I9000 using Tapatalk

Try to flash a new kernel again. It may help you updating some files that control wifi.
I used onavo for couple of days, battery drains. Its functions already in ICS roms, Less but good.

Thank you so much! That did the trick. The onavo garbage seems to be gone for good now.

Could you please tell us about the battery usage. Do you noticed some changes in battery life?

Nexus 4 losing mobile internet when idling a long time in wifi

Hello all,
currently my Nexus 4 is losing it's mobile internet connection when i am a long time connected to a wifi. I am on O2 germany as a carrier, when android was much younger, like 1.6 i had the same issues, but somewhen on android 2.X it was fixed.
Somehow it looks like in 4.2 it's now the same issue
When i am just a few minutes in the wifi and lose wifi connection like moving away from the building everything is fine and the nexus 4 is switching to mobile internet
when i am a few hours in the wifi and to the same it's not switching, i've got cell connection for call and text but no Internet,
switchting from 2g to 2g/3g fixes it then, but it's somehow annoying
any ideas or anyone with the same issue?
edit:
seems that people are having the same issue on the galaxy nexus too, but even with older android versions

it actually happens to me as well. I live in Australia and thought the problem lies with my provider. And yeah I can get the 3g connection back when i tried to change to 2g then back to 3g connection. Has this issue been reported before? hope it can be fixed soon.

This has happened to me twice since I got my N4. I'm in Canada btw. I wonder if it is a frequent problem out there.

Me too...is there a fix?

my solution so far is: airplane mode on -> airplane mode off

This is what I usually end up doing. Although it sucks that a phone of this caliber has problems with this.
Sent from my Nexus 4 using xda app-developers app

Im having the same problem. Doesnt matter which rom im on. Been on stock, modaco, and some PA rom with this problem. Also used matr1x kernel and franco kernel. Solution for me is to jump into airplane mode and back.

I'm in the same boat and only quick fix is airplane mode on/off.
Sent from my Nexus 4 using xda premium

I have the same issue.
I dont know whose fault it is, Google, LG or my carrier... but it's quite frustrating from time to time.
I thought i had solved it by activating "choose automatically" in mobile network settings> network operators.
It worked yesterday and this saturday, i didnt drop 3g connection when i disconnected wifi.
But i lost it again this morning as i left for work, just like last week...

I've had this problem since 2.1. I seem to remember it being on the Google fix boards. The aeroplane on/off is the easiest workaround. But, still, it's annoying, and it is also not consistent. If it makes you feel any better, the same issue arises on iphones. This suggests it is not simply an android issue, it might be interesting to know if bb or wpx does it.
Sent from my Nexus 7 using xda app-developers app

i think the issue is neither LG nor Google
i think it's something with qualcomm driver and the provider
because on older devices i had with qualcomm chips had the same issue
the sgs2 and the hox which had exynos and nvidia chips didn't had the issue

Idk if knowing that others have the same problem makes me feel better, i just hope they can fix it.

That's likely the one, I'll rely on your veracity.

so if you check the google support forum thread
it looks like a lot of users are having this issues
i don't undersand why google is not even giving a statement

It happens to me very often, because I turn off data overnight. Airplane mode doesn't help, the only thing that brings connection back without reboot is Mobile Networks -> Network operators -> search... It finds my operator again and connection comes back. I had the same problem with Galaxy Nexus 4.1.2 (fixed in 4.2, though), but airplane mode did the trick there.

Its quite annoying to restart phone every now n then everytime internet stops working.
Also, tried Airplane mode on/off its worked.
Are there any experts that can help to resolve the issue for a better & permanent solution....?!

GS4 data very sporadic

My s4 data is bad to kick off and back on. It has done had since I first got it. I have 3_g at home and it's very solid signal, I never lose signal in fact i keep 4-5 bars but data kicks in and out all of the time. My old phone was very solid never lost data signal ever. I have tried the 3 different radios and several ROMs but they all do the same thing? It doesn't show roming and it looks to be on sprint solid. I know I've read about losing data due to flashing but mine works fine then it doesn't work, off and on, off and on all of the time... Rebooting sometimes brings it back, switching radio off will sometimes too but sometimes I just have to walk away for 10-30 min and it'll pop back up... any ideas?

I will assume that you have updated PRL and profile. If not, do so. If that does not solve the issue, call Sprint to see if thry are working on towers in your area.

Yes I did update profile/prl as well. I have a second phone we keep in the house (as my house phone) but it keeps data signal just fine never drops either. I haven't called Sprint I may try that but I really think its buggy firmware

I called Sprint, wasted 10min of my life lol. But I set force cdma, we'll see how that goes. No lte here anyway.. in fact 2g some of the time.. gotta love sprints data (shoot me)
Sent from my SPH-L720 using xda app-developers app

Hope the problem works itself out. One last suggestion would be a factory reset (that is if you didnt wipe data through rom flashes). Doing so can potentially fix a lot of different isses....maybe this as well. Good luck

4.3 keeps dropping internet connection?

Hi, I've had my nexus 4 for about a month now, when I got the phone I automatically updated to 4.3.
Since the very first day I've had it, it has kept dropping internet connection randomly multiple times everyday? The signal bars will go from blue to grey and stay like that until I either reboot the phone or turn on airplane mode then turn back off again.
Its becoming a constant hassle trying to use the internet because it keeps hanging.
Has anyone else come across this problem? If so what did you do to fix it?
Thanks alot
Sent from my Nexus 4 using XDA Premium 4 mobile app

Do you mean WiFi or carrier data? And how good is your carrier signal? You can try flashing a different baseband.
For WiFi, try turning off Wifi Optimization.

Its the carrier data that keeps dropping, I also get full bars most of the time.

Its surely a baseband problem..nothing to worry..
Just try different basebands and test them and see what works for you,but for that you need to be rooted..
Before you asking or creating a new thread refer to efrants thread for unlocking and rooting.:good:
