If you want to buy a new mobile phone then you have to be cautious about many things. Buying a new mobile phone is a great thing. You should buy a phone that has minimum 2GB RAM and atleast 16GB internal memory.
However it is not applicable for many user but I say in a general condition. If you buy a phone which has less than 16 GB internal storage then you will suffer from storage problem. So before buying a new phone you should look after the storage capacity.
