Phone freeze

hello devs :P
I have been playing this game for 3~4years now
and i still love it thnx so much for cool updates
so here is my problem when i farm in vampire feast my phone freezes:(
is it wrong with my phone? should i lower graphics??
and another problem ; it takes soooo much time to log in now
it was ok for just few hours ago
it seems other players are having same problem
THNX for reading this hope the problem gets fixed
<PS can we get platinum for daily blessing?? it used to be so good but now i keep on getting shields>
