can anyone tell me about the service centres of samsung in dehradun ?

I have purchased galaxy s7 in feb at 22990. I have so many chocies but still I chose this because of it's features like water resistant but I think Is that a bad decision. Still ot getting oreo till now ! It is June. Frustrated.

I want to tell you all that within this week. you all will receive oreo update with samsung feel version 9.0 and with security patches. ! :)

Will i get Face unlock on galaxy S7 after oreo update ?

when galaxy s7 will receive oreo update in India ? waiting eagerly...
