A55 5G calls issue: "Can you hear me?"

[mirok]

Many people report problems with this phone during calls.

The call works normally for a while, but out of nowhere the other party stops hearing me during the call, but I can hear them. It's irregular, sometimes it works, other times problem repeats. It's not a microphone problem. This is most likely network related, where the network switches and adapts to the signal intensity (like from 5G to 4G or 3G). The issue is not in areas with strong signal (where the switching is not present). Older phones don't have this problem (like A32). This is a very annoying issue, as you always have to hang up and call again.

Please don't recommend nonsense to me like "reset network" or "turn off 5G", because I did all of this and all combinations. It is most likely hardware / firmware related and Samsung should investigate it, take it seriously and release a firmware fix. This problem occurs on all A55 5G in places where the signal switches (for example, you are on a phone call and go from one room to another with a weaker/stronger signal or network).

The only setting that slightly fixes this problem is to have "mobile internet" constantly turned on and probably disable power saving on the calls app, also turn on LTE calls if possible. However, it is not a definitive solution.

To be a little more specific, I am located in Slovakia and mobile provider is Telekom.

This being a forum for Samsung members/customers, Samsung won't see this, so the only thing we can do here is give troubleshooting methods—we can't provide a firmware/software fix.

Have you attempted to contact your network provider? Have you tested your SIM in another device? Is this problem occurring on all phone calls or only with specific people? Both ends need a good signal. As I would say, 90% of the time, that's the issue. The reason I say this is that if it were an issue with all A53 5G phones, then the forums would be packed with related posts; it would be everywhere on the internet.

As said- is this will all calls you make or specific people?

As mentioned above, these forums are for members to members (customers).

@johnz237 Thank you for your reply. It is occurring randomly. SIM was used previously in other phone (A71) where it worked for years without single call issue. When I put SIM back into A71 it works again without the issue. So it is related to the A55 5G. When I turn off the 5G network, the issue persists, so it is not 5G network ... and A71 has 4G or LTE and also this network switching between signals and the call is working.

How odd. I would say submitting feedback via Samsung Members would be the way to go, to get this information into the right hands.
