SAMSUNG its a one of the top brand in the word.
-coming to the j2 pieace its a very cheap and best phone.
-its features are quite better and I use j2 piece.
-its usage is good and even not little bit heat for continues working
-compare to other brands its better for that price but other brands like redmi gave more features than this pieace but its heating for using more than half an hour .
So, internally some damage will br done
