You can try a wipe cache partition to see if that solves the problem!
Power off the device, while powered down, press power button and Volume up button simultaneously until the phone vibrates and the Samsung logo appears. Let go of buttons, you will now be in the bootloader screen, using the power button for Yes and the volume buttons for scrolling, scroll to Wipe cache partition, press power scroll to yes, press power, reboot press power.
If this doesn't work I would take the device to a authorized Samsung service center to have it evaluated.
