My galxy j7 have been using since 13 months no techinical issus, no heating up , good battery backup with 2500 mah battery. Although ram is 1.5 gb can absolutely bet other phones having ram of 2-3 gb. Overall quality is best nice speed and smooth functioning. This phone also have special features of s bike mode that make a unique feature the Camera quality excellent and front camera with 8 gb along wuth front flash made it aeye catching smartphone if ever. I think its the best phone to but at this price.
