  1. Hi Selva.
    Thanks for the info on galaxy A40s which is made for china.

    1. Please do you advice me to buy this phone considering that I will be using it in Nigeria.
    2. Will I encounter any problem like software update, security patch update, etc. in Nigeria.
    3. Does putting multilanguage Rom and google play store make it vulnerable to brick.
    3. Can the apps made for the China market be removed from the phone?

    • It is always wise to buy your region mobiles. You will get Software support, and anything goes wrong you can claim under warranty within your place. A40s is exclusive to china region. You can buy A40 or New M30s which has 6000 Mah battery with 48 MP Rear camera; The price is more or less same. Other than this you want this model, Yes you can use this in your Area. When software update hits, Use china VPN to get the update. Most of the time, it works.
