Default [Q] Sim card detection problem

The last days my phone has been having trouble detecting my sim card. The things I've tried to do to solve the problem is to take out the sim card, factory reseting, reseting to the latest upgrade through LG's PC suite.

The thing that works is factory reseting and this works a while but then my phone stops detecting my sim after a while and I have to do it all over again. First I thought it was rooting or xposed modules that was the cause, but then I made a backup with LG's tool and after rebooting the problem occured again.

Anyone had the same issue?
