Let me share a thought for everyone's mind. Don't ever trust chinese oem's on updates.
Expensive disposable smartphones, sadly. Each year Google and Apple put "slowdown bombs'' in the firmware so that there is no way to use our tech more than 3-5 years.
P9 Plus ?! I paid 650 euro last year for this flagship and still 7.0 and many software bugs, outdated security and so on. With this attitude, disrespect for customers you will have no future, no way to gain market share.
