Actually I recomennd all the teenagers to buy samsung galaxy j7 or j7 prime
J7 prime is little bit larger but j7 is cool mob its battery capacity is 30000mah and it consist of 13 mp rare back cam and 5 mp rare front cam which seems to Be awesome clarity in just affordable amount it has 2gb ram and which is very suitable for internal of 16 gb its cool and affordable
Its super cool and its hang proof too it supports a bigger version of games like asphhalt 8 and u can also install the great immortals and gta san andreas too
