Samsung a disgrace.

Bought an S8 in March.. Following an update recently from Samsung...all my sensors which include the iris, gps, magnetic stopped working..and according to this page https://us.community.samsung.com/t5/Galaxy-S8-Questions-and-Answers/Samsung-S8-plus-all-sensors-not-working/td-p/288310 many ppl have been suffering from this and the only option is to change the motherboad. however, the company is refusing to do so because of a cracked in my screen using typical lacklustre excuses to avoid helping...so at the end of the day I have a 10 grand smartphone but which is worthy of only 400 rands....i had S4 then s6 then s7edge before i moved to the s8...suffice to say this is my last ever phone from this so called great company.
