Review : The primo R1 phone has 1.21 GHz CPU so it will run the phone very well and dual core but it has only 512 mb RAM so it is the bad side of the phone , It it will take more place when installed apps . screen size is 4" for this it is comfortable to carry .It has Battery only 1500 mAh so its charge will remain 1 day with rough using .camera is 8 mp so that you can take high quality image .There are many kinds of sensor that will help you to enjoy the phone . Fm ,WIFI and GPS is the most attractive of this smart phone .
