Which mobile phone is better apple or Samsung? This is endless debate. Every mobile phone has its own features. in my perception the Samsung Galaxy has been a good mobile and users can visit website for reverse phone lookup. We all know that Apple is best for security but it can be hacked. But both are good in quality and service.
