I bought a samsung Galaxy model GT-S5570 on the 16th of June 2011. Today is the the 11th of July (Less than one month.) This instrument has already been to the authorized service center thrice (3 times). The wifi tends to get corrupted and stops functioning. The service centers reload the software and in a matter of a few hours, the problem arises again. can somebody tell me as to what i can do in order to get this damn instrument working?
