[Q] S3 mini signal problem
Hi, I have an issue with the signal on my s3 mini. The problem is, when someone calls me, it says that I'm unavailable, and they get the sms from the provider that I'm available again, but when they call again, same thing happens over and over. There's also a problem with sms, cause I must click resend a few times to send the message. I tried factory reset, changing providers and nothing. Anybody might know what is the cause of this? Thanks in advance.
p.s. Sorry if I posted this in the wrong section.
