Hi,i would like to know,what is the updated M51 phone.For me M51 phone quiet nice because it chipset and big battery for long screen time.It almost perfect for me.I am using it for my delivery job and dont need a charger while working.Hopefully samsung will make another updated with higher quality for their new version of M51.
the newer version of Galaxy M51 is now Galaxy M53, which is the successor of Galaxy M52. Higher quality is promised. you might want to usha this product. I have attached the link for you
