Samsung J111f mic issue not getting resolved

<p>Samsung is supposed to be a trusted brand, but this hasn't been my experience lately. Today I handed in x3 Samsung J111f phones at their Samsung Smartcare service centre at Century City. All three these phones have exactly the same problem. About a minute into a call the person on the other side struggles to hear. This is very frustration to say the least. If the phone is switched off/on it takes a while for the fault to stick out its ugly head, but within a day or two it will. </p> <p> </p> <p>The one phone went to Vodacare The Hub at least twice. First they did software, and on the second job they did a PCB replacement, but the problem wasn't resolved. After that the device was sent to Samsung Smartcare, where they also did a PCB replacement. Needless to say it didn't take long before the problem started again. </p> <p>The other two phones have exactly the same problem, but because the first repair was a waste of time sending in, I haven't sent in the other two devices. They've just been lying in a drawer for months because of the feeling of despondance the "repaired" one has caused. I've been told that the mic is attached to the PCB. My question is: If the PCB has been replaced twice now, what else is there to do? I would like to have the option of taking another model of the same value, or pay in for a different model that is more reliable.</p> <p> </p> <p>My Job numbers are ********** 424, ********** 577 & ********** 245. I have no doubt that the faults will be replicated, but only if they take the time to test it properly.</p> <p> </p> <p>I hope Samsung can come to the table on this as these three phone are just paperweights at the moment.</p> <p> </p> <p> </p>
