Everything looks great, AMOLED 4gb RAM, 5k mAh.

The only question is whether Lenovo will give OS update.

If intention to have 2nd phone as back-up/standby, better get the Xiaomi Redmi 4 Prime or Redmi Note 4/4X for "half" the price of P2.

It'll be a waste to have P2 as 2nd phone due to beautiful Super-AMOLED panel, loud external speaker and swift stable OS not being used fully from 8AM to 10PM for 3 days straight.

However, to have P2 as 2nd phone will be long term investment because it has the reversable charging/powerbank feature to re-energise the 1st primary phone on-the-go. Also, the 5,100mAh energy capacity will make P2 to last for 5 years (remember Nokia 3210 & 3310...? Just buy a brand new replacement battery for 4 times...one each year...). At the 5th year, P2 energy capacity is estimated to be 2,000mAh if we know how to take care of the built-in battery properly and provided Super-AMOLED screen is still workable... Can become "harta pusaka" aka inheritance to our grand-child later...LOL...
