The mobile data on this phone (SM-S901B/DS) drops temporarily when receiving a call, it goes from 5G to 4G, then to 3G and then finally to H+ (2G) and this lasts for about 10 seconds and interrupts the connection, it screws up my Clash Royale matches whenever I receive a call. Is there any fix? Is this network/provider dependant? My previous Poco F3 with a Qualcomm SoC did not have this behaviour, it would remain on 5G without interruptions when it received a call.

Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?
It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?

I am facing a problem related to 3G data connection.
The problem is as follow, while having a talk (voice) many times the data connection (3G/H) drops due to some reasons and never re-established until phone call is over.
I found this to be very annoying, if no phone call been done the data connection is perfect 99% of the time but doing voice call disconnect the data (both 3G/H) and never re-established until the phone call is over.
Once the call is over, the data connection resumed (3G/H indicators shown)
Please advise
Thanks,
Because the voice call needs your connection to the operator and that's why the data connection is terminated while the voice call is active.
Happened to me on every phone (LG KU 990, Samsung Omnia, HTC Desire).

You are correct but...3G/H supposed to allow data&voice in parallel, and sometimes is does work such. But once the data connection terminates it never re-established until voice is over.
You are right, but not at all operators, just tested ORANGE SK with HSDPA signal... drops after a voice call is beign made.
BTW, are you GSM or CDMA?
Just learned, that if you are using a custom ROM, can make this problem. Also are you set to WCDMA preffered in the *#*#4636#*#* menu?
GSM
yes - WCDMA is set
Network type - UMTS
Is it just a case of the icon disappearing during the call? Try starting a download whilst on 3G/H/E connection and then make a phone call, switch to the market and check to see if the progress bar is... progressing (excuse the pun!), if it is then data is still active. If your on a GPRS network, data would be disconnected for the call.
I bought the N7105 from Phones4U and unlocked it to use when my SGS3 LTE was playing up but since moved my 3 SIM into the phone. It was working flawlessly for about a month but then started, maybe once per week or once every second week, getting fixed in a state where it seems to think that there's no mobile signal. Fair enough, sometimes I lose signal, however when the signal comes back the phone remains stuck in this condition. HSPA+ data is working, it shows the correct network name and can receive incoming calls but the "no entry" icon is in the notification bar and when I try to make an outgoing call I'm prevented from doing so with an error message indicated "The selected mobile network is not available". Disabling the data connection, searching for networks and toggling airplane mode don't seem to help and I can only make outgoing calls again by doing at least a soft reboot. The device is not rooted and is running stock 4.1.1. Has anyone else experienced anything like this?
Hi all,
I can't receive any calls or text on my Redmi 1s when my mobile data (3G) is on. I've tried this on both Mokee and Paranoid (and have no plans to go back to stock). I use BSNL 3G, if that holds any relevance.
Any way I can change the priority that the phone is assigning to 3G so that I can receive calls and text normally.
Anyone else facing a problem of lost data connection during a call? It happens even even with wifi connection. I sometimes need to use the internet during a call... but the internet connection automatically disappears for the duration I'm on call. As soon as I end the call everything is normal.
When on LTE the phone automatically switch to 3G/UMTS during call (VoLTE is not supported by much providers yet).
During the switch if you're in a bad 3G area or with many people on your cell data connection is lost, the phone gives the priority to the call obviously. LTE is working very differently so that's why you can have a nice LTE data connection and without moving a ****ty UMTS data connection.
I've managed to browse web during my calls without issues on the 5T.
