Should i buy galaxy s6 inspite the swiftkey bug in it? I love the phone

[AC Question]

If you all went though the recent news galaxy devices can be hacked including s6 Firstly i use only home private WiFi and not public ones...so if i buy my s6 will i be at risk? And if i buy it month later ill not get the knox update to solve the problem?? Should i still buy the s6 and if yes ,when? Im selling my current nexus 5 for it
