The actual weight of the J5 is 159 g that is pretty heavy I would say
And It has 5.2 Super amoled display
and it has 282 ppi that is pixel per inch
that is pretty low I would say
but that Display Quality is Gud
The battery is Ok
its is 3100mah that is gud for that phone
even the amoled display save the battery so u get better battery backup
its internal is 16gb
and u can Expand it upto 128 gb that is pretty good
