100 percent but it wont be on October 21st probs starting or November or mid November

then note 10 note 9 s9 probs in the span of 10 days to 2 weeks and then midrange

is this ur phone or someone in America or korea

depending on ur phone if u have an s10 probs in a few days as india has a large fanbase for samsung if u have a note then 1 to 2 weeks and if u have a midrange phone probably 2 weeks or maybe even 10 days
