1.66 question.

Hi everyone.
Since upgrading to 1.66, I have noticed something rather annoying and hope someone can provide a solution to fixing it.
When I was on 1.48, the H icon at the top of the screen would always be there. I was effectively connected to the internet all the time, and was able to leave MSN messenger etc open and I'd always be online.
When I upgraded to 1.66, the icon at the top of the screen is always 3G. It only changes to H when I'm actually using the internet. If I open the browser and check out a website, the 3G changes to H and the website begins to load. It changes back to 3G when any internet connectivity is idle.
I can only access the internet when H is displayed, but I want it connected permanently like it was on 1.48.
It's like the phone is disconnecting from the internet when I'm not using the browser. It's not very useful when I need to keep MSN messenger open all day.
Thanks.

It's not disconnected when it says 3G. It simply switches to the slower mode when nothing is being transferred to save resources. As soon as something actually needs to be transferred it goes to H again to get the fastest available speed.

Ah, okay. I can't seem to visit any websites when 3G is displayed though. Perhaps that could be to do with my operator settings or something?

i have had the same problem since installing the sms patches.... i have since hard reset to remove the patch... and testing it now... it is very anoying because it keeps my msn disconnected...

I'm using Dutty's 1.5 (it's a great ROM!) with a 2.07 radio and I've got the same problem..
When it says 3G, nothing seems to come through.. when it changes to H, the webpage starts loading...
Does anyone have a fix to make it not switch back and forth between H and 3G? It gets frustrating because it often takes 1 or 2 seconds to switch between the modes....

Let us know how to you get on because I need this fixed.

My MSN stays connected fine in 3G. Push email works perfect too.

The icons only show the available type of signal.
They don't mean you are connected.
When you do connect by opening an app that uses the appropriate signal then the icon changes to show the signal that you are connected with.
If H is not available in a particular area then it will stay on 3G and if that's not available then G with show.

Hey guys. I'm on my 4th HD2 handset now since upgrading my vodafone contract one month ago. First two handsets had similar probs as allot of you have had, i.e sms not working, alarm not working etc etc. I upgraded to the 1.66 rom when i got my 3rd handset from phones4u. I then started getting the same issues as you just described- internet only profficiently working when H coverage is active. When it goes below that then nothing happens at all. I returned the handset today and got a new one. This one already had the 1.66 Rom update installed and sure enough, had the same internet issues. I started fiddling with settings and changed the band setting from 'auto' to 'WCDMA'. ( just trial and error, so senior members please chime in if i have given bad advise!) This seems to keep the network coverage constantly in H and since changing it several hours ago i have not had any issues.
Start> Settings>Wireless controls>Phone>Band> Change Auto to WCDMA
Give it a go!

Wouldnt that make the phone stick to the 3G/HSDPA/WCDMA band only and cause the phone to have no reception around certain areas that still operate on 2G GSM?

Exact.
I rather tend to do the opposite for that reason if I have trouble (sometimes you're in areas where 3G reception is low and it keeps switching between 3G and EDGE all the time), I'll force EDGE only. It's slower, but at least the connection is constant.

When at work mine fights bewteen 3g and h and both are like 1 bar signals, i'd rather disable both when at work as G is full signal.
Is there a way?

[Q] Data connection and other 3G problems..

Hi to all SGS2 fans out there
I'm a happy user of SGS2 but I noticed some problems during WCDMA usage. After few minutes of using 3G/HSDPA connection is still looking good on the signal bars but I'm unable to open any webpages/android market etc. I have to disable and re-enable data connection in settings to get it back working... for another couple of minutes..
Secondly I have short breakups during calls. When I'm talking to someone the phone mutes for a second. It doesn't happen every time - but it's quite often.
I'm currently using Lightning ROM 1.5 - but I had the same issues on 1.4, 1.2.
When I'm using GSM only - everything is fine.
Do you think I have a faulty unit?

I'm getting a similar issue. Currently on VillainRom 1.4. Full 3g bars but cant use browser, market, etc.

hi,i have just sign to forum now,i was looking around and seems like very populer here.
Anyway i have same problem here plus when i have 3G or HSDPA on my bar it is changing every few seconds (for example a few seconds staying 3G and a few seconds staying on HSDPA,not stable and non stop) and seems no stable and killing battery.I have already change my phone and sim for this reason under my warranty,if anyone give advise for this problem it will be really helpfull,thanks.

its a normal thing when some kind of background data or sync or net is active it will turn "H" and when not internet is active it will stay "3G"..

[Q] 3G connection problems after leaving WIFI on Note 3 [UK]

On my Galaxy Note 3, when at home I am connected to my WIFI. When I leave the house or switch off my WIFI the phone seems unable to connect to the network (in this case Three) and the browser, email and any other data apps state they cannot connect to the Internet.
The only way to resolve it is to switch on Flight Mode and then turn it off again. I saw a comment in the reviews for the Note 3's keyboard fix that one other person is experiencing the same as me.
Is anyone else having this problem and do you know of a permanent fix? The only info I can find is a similar issue on the Note 2 at time of launch which look to have been corrected by a patch.

i have this problem so i flashed h3g uk firmware and it kept failing, so i flashed back to uk btu firmware and im stuck with the exact same problem. no idea how to fix either,
p.s my problem only seems to be with google now, play store and sometimes on any app that uses internet i get news feed error no connection ect..

I am on Three network and mine works OK.

Solution
I think I have found a work around to this annoying problem. It was losing the ability to use any data when I left a WIFI spot I was connected to, or when out and about and the phone picked up an open WIFI spot. None of the WIFI advanced options made any difference. It would affect 3G data too, I'd lose all data access until I toggled Flight mode off & on...that was the only way I could get it working again other than restart the phone.
I found a post about a similar issue with the Note 2 when it was first released and it mentioned a WIFI power saving mode. It turns out you can get to this from the SeviceMode screen by dialing this number *#0011# (ServiceMode will start as soon as you enter the second #) - assume it is the same for all. Once in ServiceMode, tap the menu button and chose WIFI. You will then see a WIFI Power Save Mode label with a button underneath. Tap the button to set it to OFF.
I've been testing this all day, normally I'd lose data at least three times, sometimes more, while travelling but so far today everything has worked flawlessly ... no loss of data connectivity. From what I have been reading, switching off power save mode does not affect battery life despite what you might think and I've not noticed any unusual battery drain today so far. So if you are experiencing the same annoying loss of data, try this before you take your phone back. Hopefully this is a software issue that will be fixed in the future.

I swapped the phone
Hi,
I had something similar, except it wasnt wifi related, it happened after I lost the signal for a while (eg, in a lift/elevator).
I tried a new simcard, and that didnt help (also Three UK).
Then I got the handset swapped for a new one at carphonewarehouse, and it fixed the issue, so I put it down to a lemon unit.
cheers

on my s4 and n3 i did more than 10 tests each on wifi and 3g with phones simultaeneously, both on same network, both held in my either hands, both using speedtest both connecting to same server, both on the three network sims on the one plan with unlimited internet including tethering (both pans in my name), same location, same times tests were done.
both on 3g and wifi the n3 is MUCH MUCH slower than the s4 both on three network and same wifi
********************* on wifi on 3G
S4 PING TIME 32 to 173 66 to 86
N3 Ping Time 30 - 37 73 to 1110
S4 upload speeds 8 to 17.79mbps 1.65 to 2.27
N3 upload speeds 7.11 to 12.58 1.74 to 3.77
s4 download speeds 17.79 to 22.38 6.61 tp 7.68
N3 download speeds 7.93 to 12.58 mbps 0.92 to 8.04
the numbers are not just it, even during speed tests i was losing wifi connection on the N3 a couple of times and see the same happening on streaming youtube where it keeps stalling on wifi unlike the s4. surely there is something wrong with the hardware of firmware

Looks like the WIFI setting only helped and it has not solved my problem. l now lose network data connection less often when leaving a wifi zone but it still happens. More worryingly on two occasions now I have lost all access to three including calls, texts and data. Toggling Airplane mode brings everything back to life but this makes the service unreliable.

Sometime I also have this problem. This is similar to when I went overseas, I turned off the data roaming, but it always unable to connect to data when I returned. Usually I have to reboot it.

same problem
Same problem any one can help without custom rom

Just got this alert as it was in my spam box hence the late reply.
Had done this comparison video of the note 3 versus nexus 5 WiFi speeds on same router and nexus 5 was giving speeds of up to 50 Mbps and the Samsung galaxy note 3 was giving 0.5mbps plus drop outs! See video https://www.youtube.com/watch?v=w-XvFPwTAGA
The router works fine with my 3 nexus 7 tablets, 3 Tegra note 7 tablets, Samsung galaxy note (original), 2x android mini PC, 2x smart TV's from Sony and LG, 2x smart bluray players from Sony and LG, laptop, smart camera from Samsung, Panasonic stranger, my NAS drives, 2x old HTC desire phones, a few other old phones from Sony and Nokia and media player from samsung and archos, the only device that ever had a problem with any Router is this Samsung galaxy note 3.
Main problem happens when there are open WiFi networks around our you have selected the auto detect in settings. Here is the solution https://www.youtube.com/watch?v=MjL8JbSQCvw and now I get 50mbps with same phone and router! So it was **** Samsung software to blame!
Now I have triple sim adapter in phone and all three give me 3g signal in Many areas.

I have a Note 3 and this always happens to me when I return from travel overseas. I turn off mobile data and data roaming and use Wifi, but am never able to reconnect when I return. The first time I fixed this by rebooting. This time I tried restarting my phone, removing the battery, turning off Wifi Power Saving Mode by dialing *#0011#. Fortunately I was able to fix the problem simply by toggling Airplane mode without having to reboot. Hope this helps.

LTE 4G problem! No automatic switching from 2G/3G to 4G network during data flow

Hello,
I don´t know, maybe I´m blind and could not find similar problem in the forum, or maybe none of you noticed it?
Since weeks, I enjoy the immediate network change 2G > 3G and 4G (just looking hat the Phone, but not used a App thats need data connection)
Today I just go on my work route and listen to internet radio for the first time again, that of course is continuously loading data.
But to my shock, I realized that he not switch from the usual point of H network to the 4G LTE network as usual.
I suspected bad and wanted to exclude the TuneIn app, and i turned on at the same time Google Maps, colesed TuneIn, scolled in Maps so that data flow´s ........ nothing happens, it stays in the H+ network, then i changed to the speed test an check the speed ..... it´s about 5 mbits, so actually still no LTE ( it does not show so well on )
I do this few more minutes and then closed all the apps at the same time. Now he has logged into the LTE network !
What a F..K is that? :-/
That means, if i'm traveling around and an app constantly pulls data, the Note stay only in 2G/3G network, because it changes only to 4G when no data flow is!
WTF!
Could someone test the same, maybe mine is broken or something like that.
Greetings Frank

I had the exact same problem on my note2 also. Its very annoying. Fortunately for me that only affects me if I am tethered, otherwise I don't have an app that keeps pulling data for too long. I have not found any solution for this issue. It seems that is how the radios are supposed to function to not disable a data connection in the middle of something.

Ehrpd seems to have fixed the whole cutting off of data streams for me when switching back and forth between networks, which is awesome. Unfortunately the note 3 seems to love 3g and hate 4g most days unless I toggle airplane mode manually.

Only with your Note 2, or with Note 3 too?
My Note 2 LTE with Vodafone was horrible, after 2 months I gave it back to the dealer and changed my contract also back. To much trouble all the time. LTE not usable if you are on road / driving.
Now with Note 3 i changed back again to LTE Test driver
It works much better, but the switching problem between 3G and 4G is really bad for me.
Which provider you use?

Same problem with my Lenovo A6020A46. It can't auto change 4G/LTE to 3G/2G. Don't know what's wrong with this ROM. Even its the latest Nougat updated on 07 Aug 2017.

[Q] Random mobile data connection drop problem with S4

Hi there,
First of all, I ran an extensive search over google and also on XDA forums before posting this.
My S4 (I9500) is experiencing random data connection drop problem for some time now. It starts with no data transfer (upload/download arrows not being active), then connection goes from H+ to H, then to 3G, then drops, back to H and continues until I turn off and on MOBILE DATA from toggle buttons. Then it works normal for some random time, then it happens again. Sometimes an hour, sometimes after 5 minutes.
I found this thread , however trying the workaround there by entering the provided code, I get "Connection problem or invalid MMI code". So that fix is not working either. I tried to go in service mode > debug screen > nas control and change revision to Release 5, but it says NOT SUPPORT. Haven't tried the other releases since I dont want to mess with it. I am also aware that the workaround in the above thread is for S2.
When this happens, it is just mobile data, there is no problem with network signal.
Has anyone else experienced something like that on their S4s?

The method you tried using is probably outdated and for a different phone.
Are you sure it isn't your provider?
Did you try another modem?

Nope.. I am working for a service provider company. Other people with iPhones in the same location as I am, are not experiencing the same thing. I heard similar problems with other S4 users, but they dont know any workaround either.
I tried both auto connect and WCDMA only options as well. Doesnt make a difference. My S4 doesnt support LTE, so I only have 3 options, third as GSM only, which I don't think it would be a solution.
Only temporarily solution so far, is turning mobile data off and on, which lasts from 5 minutes to 1-2 hours.
Btw my android version is 4.4.2
