[Q] NxS jumping between 2G/3g?

Anyone else having a problem with the NxS jumping between 2G/3G network all the time?
I tried 2G-only and it seems the it does interrupt connection less often, but it still does. I'll exchange the sim card tomorrow to rule out the last option (I can think of) I got before returning the NxS and asking for a replacement.
(i9023, stock rom/kernel/radio, tried 3 stock roms with diff radios (KA3, KB3, KD1))
Maybe anyone got an idea or a hint.

Sounds like ur in a weak 3g area so it keeps goin back to 2g

Granted I'm not in the best 3G area, but I usually get 3 (of 5) bars in 3G and then it just pops back to 2G.
Might be network pumping (or w/e it's exactly called), gonna exchange the sim anyway to track down the problem further.

Are u on orange in the uk

I have this problem aswell. Thing is 2 3g bars are way faster than 4 g bars. I cant change it to use only cdma in the service menu. Anyone know why.

So does change of simcard help?

I got it fixed for me. I tried n3 and n5 sim cards, no changes. Problems were caused by faulty antennas, after being fixed by the carrier problem was reduced to a minimum. Now to get rid of the so called network breathing, which is a problem of the used communication method itself aka can't be fixed. University ftl!! Simply too many smartphones

[Q] samsung galaxy plus as a phone

Has anyone been able to get this to work as a phone? I got the original tab to do it but you had to change the modem to 2g mode and that made the internet worthless. Wondering if we can get it to work on 3G with phone.

What model is your tab?

I use mine as the phone in some cases and I don't have to change the modem to 2g. I have a p6200 version with stock ics and it works great without changing anything

I'm guessing the op has either got a wifi only model, or a data only sim inserted, I can't imagine any other reason why he would have difficulties using the calling feature

Dropped calls!

Friends,
Quite frequently calls are being dropped with my s6. Suddenly the network completely disappears from full bars to nothing. I've tried different modems, no help.
?
Anyone experiencing the same problems?

Guys I can't believe this. I am convinced that more people are having the same issues with 4g network stability and dropped calls!
Please sound up and let us know.
The GSM network stability is nowhere as stable as with my last s4
My problems include the following
- dropping from 4g to lower speeds, even edge when trying to so something data intensive (browsing)
- dropped calls and random network loss while triggering network activities (browsing, refreshing mails, calling)
- trouble establishing calls. When the network drops out I have to wait about 10 second until I have bars again.
Please let us know how your device is behaving, what might be causing these problems and how to fix it.

Sadly, there are quite a few threads about dropped calls on this and other forums. Some have tried factory resets, unchecking "HD enhanced LTE services", removing LTE altogether, etc. Some report their caller cannot hear them. Perhaps 5.1.1 will fix some of the problems, but that's assuming they're software related. I'm personally wondering if it's a problem with the antenna placement. Some carriers like Sprint in the US have had so many complaints, they have issued special patches. Keep checking the forum and hopefully a solution will be found.

Thanks, I really hope it's a software problem. Sometimes even my Bluetooth connection to the car breaks up. It's like the radio is unstable and reacts when stressed.

Anyone else with these problems ?

My S6 had a poor signal from day 1, it fluctuated a lot and couldn't hold onto network signal well. I sent it for repair to Samsung and I am picking it up tomorrow (they said they have repaired it) so we will see. Maybe everyone needs to send in their device to get repaired.

Same thing happening with my wife's AT&T S6 Edge. The S4 never had the issues in the areas the S6 is having problems with.

Maybe everyone needs to send in their device to get repaired.

It's unbelievable. Samsung is really testing our patience with this device.
- display tinting
- bad reception
- scratches out of the box
- inconsistent home button and volume keys
What's next?

I have none of these issues barring tiny tint on display. They aren't testing my patience. American carriers are notorious for dodgy reception and signal and dodgy software.

Doubt it's the carriers fault. I'm in europe and I'm having crazy dropped calls everyday

Device came back UNREPAIRED! Guess what?! They replaced the display assembly and camera lens cover!! These things were not faulty, not even the issue I sent the device in for. There's no engineer notes other than telling me the display and camera lens cover was replaced and the repair is completed. They didn't even look at the issue I sent the device in for which is poor signal, and the issue still exists!
I've booked it in for repair again! Samsung didn't understand why the repair centre didn't even look at or mention the issue I sent it in for so they booked it in for a "soak test". It's an "Authorized Samsung Repair Centre" that the phone goes to, not actually Samsung themselves. I called the actual repair centre and they told me that their engineers do not read the notes, they just go through a certain procedure with all devices and repair anything they find to be faulty. They said the screen and lens cover may have been replaced because they could have been damaged upon the engineers opening the device.
It's just poor service, very very poor service for a brand new device.

That's depressing. Exactly why I didn't send in my device. Sorry to hear!

My G920FD (Dual Sim) has same problem in Europe, poor reception on 3G and 4G , signal level fluctuated, on GSM i have a lot of call droppings. The phone working well only in the places where the signal strength is very good.

Still can't see that it's the phone. I'm in the UK on O2 network and even when signal is on 1 or no bars I get 0 dropped calls barring one which was the other party in a dodgy signal area. Faulty phones maybe, but general issue with the phone, no way.
I think the amount of replies to this thread proves my point

My phone works just fine now after flashing the latest 1.4 rom with custom kernel.
I'm sure it's a software problem

What happen in this case ??

Airplane mode?
Sent from my XT1063 using XDA Free mobile app

Airplane mode bt the others no....the phone rekognize the card bt do not have signal at all and the wifi&bluetooth they turn on by they don't find any device :/

Try to get latest factory image from google and flash it. The problem may be in radio. Its much worse if the IMEI partition got corrupted somehow or it got wiped, what i know the only way to recover it is to use EFS backup.

I already updated it b nothing I opened it and the motherboard was damaged I think :/ ...I will take it to service tomorrow!!

Note EDGE data connection not working

Hi,
I have a note edge n915G. It was passed down to me. Previous owner never uses data connection.
When i took over, i realize if i switch on data, my signal seems to drop a lot from H+, H to edge and then emergency call and no signal. It connects and disconnects constantly.
Also, it NEVER connects to 4g eventhough i have the right settings and my 4G is working on my other phone.
Flashed CM, stock rom from different n915g country and etc and it doesnt seem to solve the problem.
Could it be a hardware problem? Now i live in malaysia and this phone was bought in Singapore so it'll take quite an effort just to send it in for warranty. Thanks in advance.
edit: even without data, my signal drops on and off. What could be the problem?

Find updated modem and flash in odin
