mobile

I have purchased a samsung tab s 10.5 lte when it was released in july 2014. After about 2 months I have noticed an issue with the device.When I play any media file from the build in stock apps or 3rd party apps like mx player or poweramp , Static sound of the content I am playing ( sound not clear- disturbance in sound quality) keeps coming from the speaker or from any earphone I connect to the device The only way to resolve the issue was to reboot the device. But after a couple of hours of usage this issue comes up again. After getting fed up with this I had given it for service in an authorized Samsung service centre. They formatted the device and in the symptoms the wrote "SW bug" and as resolution they wrote "SW updated". Now after 2 months after the service the same problem has started again. My device is not rooted and is running on android 4.4.2 . I have purchased the device in United Arab Emirates. Please suggest any other solution to this problem.
