And HK users rejoiced.
the flood gates are now open for those freaking out because it didnt land on their device out the gate like it did for others lol.
its sent in waves going by serial number batches so it doesnt overwhelm it. you can also manually try to search it once you see others are starting to get it..sometimes youre lucky and it pulls it right off the bat..other times it might be a while.
personally i would hold off for a few days to see what all issues people run into before pulling the trigger..thats how i usually do it..well usually..this last one i just went for it but lucked out and didnt see any issues some others have seen. running rather smooth on my end with my M7.
i thought it was starting up this weekend?
