First and top most priority to provide carrier aggregation.lot of network issues.worst buy Samsung m series.never recommend to any other to buy m series phone from now.
A series is better than M series in many ways: 1. A series have knox security. 2. A series get updates faster than M series. 3. A series have are better optimized and give better performance than M series. 4. A series is full of features.
yes..eventhough m51 is almost close to premium midrange category still they cut down few features..no CA ..some additional features missing as we see in A series phones..totally disappointed work by samsung
