hi i'm planning on buying a new smartphone and i'm having a hard time.
i've been using the iphone for the past few years and since then lot of different OS for phones has came out. I have a few questions about them
1. a phone with andriod or windows. Am i able to upgrade to the new os when a new one comes out? ( like the iphone) does it cost money?
2. which os has an app store like apple.
i know it may sound like i should just get another iphone but the carrier lock is very annoying and also i live in taiwan now so these are my only choices now.
