Phone call problems

[JaneyB]

When I make a receive a call half way through the call I get a garbled/robotic sound and the call drops out, it doesn't do it everytime but it's frustrating, also on messenger when you are talking it sounds like something is crackling in the background, my phone( samsung a12) is only 6 months old and I still have 2 and half years on the contract, I never had this problem before with o2, I've tried swapping the sim, I've called o2 and they said it could be a network problem, has anyone else had this problem?

Sounds like a faulty phone, you would be best speaking directly to samsung via https://www.samsung.com/uk/support/

And they will recommend the best course of action.

It's an often reported problem.

Check for network issues here O2 Service Status and if nothing showing, report it through the my network app.

Thank you, I've rang Samsung and they haven't given me a few things to try but won't really know if they have truly worked or not until it happens again, and o2 did say something about the network and they are working on it but who knows, thank you anyway guys
