Hi,

I have this quite rare problem. Sometimes, when somebody tries to call me, the call will go directly to my voice mail without even leaving any indication of the missed call to my phone. I discussed this problem with my carrier (Elisa) and they think that the problem may be that when I am in 4G network, the phone can't switch to H+/3G/2G fast enough to handle the icoming call and that's why it will go straight to voicemail.

After that to phone goes in a sort of limbo and all incoming calls are going straight to VM. Restarting the phone remedies this, so I think the problem lies within the phone, not the carrier.

This is quite a rare problem but since I use my phone a lot in my work, it occurs at least bi-monthly. Somebody sends my an email saying they couldn't reach me, even though I've been looking at my phone all the time. Really annoying.

I have a theory that if I am using 4G (surfing the web, using spotify) it triggers this bug but I've not been able to replicate it yet.

Anybody else with this problem? Is this something that could be fixed in an update?

Hello again @arulrajah,

I see. Have you been able to try rebooting your device to safe mode? If the same thing still happens while in safe mode I would suggest a software repair using Xperia Companion as the next step.

I've experienced the same problems for a few months. I can add that when making a call it takes a long time for the phone to connect to the network and text messages typically arrive 10 min after being sent.

My phone has been set to prefer using the 4G network over 3G and GSM. I have always assumed that the phone when using that setting would automatically and continually chose the network with the best signal. This is not the case.

Today (after yet another missed call that went straight to VM) I checked the signal strength while the phone was connected to the 4G network. It was appalling ranging btw -100 and -114 dBm. When making a call the phone switched to HSDPA/3.5G and the signal strength went up to -75 dBm. After the call the signal strength dropped dramatically as the phone returned to the 4G network.

I have now switched the network setting to HSDPA/3.5G, rebooted the phone and will see what happens. Hopefully my calls will come through. But it is not a solution. I need 4G for certain services and the phone's ability to pick the best network is crucial.

Tried both the Safe Mode & the repair option. But, still the same.

@arulrajah, are you still experiencing this if you use another SIM-card? If so I'd suggest that you contact your network operator about this.

arulrajah

Even with another SIM card from another provider gives the same problem.

Didrik

@arulrajah, if you still experience this after what you've already tried and if it still happens when using a SIM-card from another service provider I would advise you to have your device sent to and examined by an authorized service centre. Contact your Local support for information about how to have your device sent in.

Kanikki,

further testing shows when this problem is occuring go to

Settings>Network & Wifi>Dual Sims>Dual Sim Reachability> and set that to on let sim 1 forward to sim 2 incase of error and vice versa that allowd calls to now come thru

I know the above does not remedy the problem but just bandaids it I like the answer someone gave about db strengty with the microwave, I am to try and relax the setting as much as possible to where we let sony make the choice between 3g forced and choiced.
