As for me, I'm perfectly fine with P30Pro. It's the phone to keep. Not sure how important those security updates are, but for me it doesn't mean a lot. My phone is working just fine, battery life is great, photos are also great. My wife is currently using my old Mate 10pro, and I must say, it's still working perfectly. Baterry is as stable as the first day. If this one stays as stable as the mate 10pro, I'll be happy. So, for me, it's the phone I'll keep as long as it works.
