I have recently bought a tablet (Sero7 Lite) and when I first booted the thing up it said that there were system updates available (which I THINK is the source of the problem). So I installed them and a couple of days later I noticed a screeching noise coming from my tablets speakers when I attempt to play sound. I thought it was just a blown speaker until I noticed that it comes from my headphones when ever I plug them I and play something (anything with sound). PLEASE HELP
Is it just a detective tablet or what. PM me for a solution or just reply.
Thanks In Advanced
P.s. Returning it is not an option.
