Hi everybody....
I am from India, Bangalore

My mega glass got broken, I approached Samsung
Service centre , Bangalore for glass replacement..
But they are not ready to accept the handset..
They told me to send it to Dubai...its quite difficult
for me....Is there any alternative way....any unauthorized
Service centre in bangalore ...pls let me know....
Any help will be appreciable....
Thanks in advance...
