First of all the price is 25990rs available online.
Sound of the phone is a bit good over A7 and Other J7 Series.
Processor is as same as other Samsung android phone. Minor changes are their only.
Camera is better, previous A & J series have 13mp camera while A8 has 16 MP camera with flash(Flash is not new in phones nowadays).
Ram is too low i.e. only 2GB and ROM is also only 32GB.
Looks is also same as samsung J7 2016 series.
The price of phone in terms of configuration is bit high.
When it comes to durability and reliability, samsung is always on top 5 in all mobile companies.
My rating will be 2.5/5
