Samsung j7 looks good in Golden colour, But in white colour isn’t, But the thing is Android version phones are stuckes so much, and major problem is Battery backup is less, when we use samsung mobiles more options that we want to use but due to battery backup we cannot use as much as we can, and mainly when the picture quality is high in any phone, the size of the picture also increased due to which more Memory space is required.please fix those issues, but operating is very easy and interesting so that customers will attract towards Samumg android Phones.
