Default Wifi issue and dead pixel

Does anyone else have wifi issue or is it just because tab 4 wifi signal is weak? I have no issue with any other devices but for tab 4, it would constantly disconnect and reconnect every 5 to 10 minutes; strangely it occurs more frequently at night. Also, on my tab 4 8" there are about 5 or 6 dead pixels at the centre of the screen. I need some advice of how to deal with this. Any solution? I try the dead pixel fix it app hut to no avail.


I live in coquitlqm, canada btw. And I have tried to call samsung, but it was a pain in the back, to say the least. They redirect me to richmond samsung store but there's one in metrotown too which is easier and more convenient for me get to. Is there anyway to tell if they replace for you a new one or refurbished one?
