I received an update 3 or 4 days ago for CRC7 March Security Patch. Battery life ain't any better. In fact its the worse now. Its pretty annoying that I have to charge my phone 3 times a day. Is there anyone else facing the same issue?

I have updated my phone to Oreo, I am enjoying it but I am experiencing some applications are constantly crashing. Like Instagram, Youtube, S Internet etc.. Is there anyone else having the same issue or its just me? Any possible solutions?

why Samsung Why..?

I bought a new S8 but unfortunately I cannot verify my IMEI number. Neither on Samsung's website nor on Imei.info. Does this mean my phone is not original?Any possible solutions?

I have a note8 used almost a week only. Battery is draining very quickly. Is there any quick fix available or is it going to be the same?
