Whenever someone asks my concern on buying second hand mobile phones I always says NEVER EVER EVER buy any electronic product second hand because the person who are selling it definitely hiding someting from you.
If you think you will check the product while purchasing then you are WRONG.
Some faults and problems in electronic product discloses themselves immediately so you can catch them but some problems arises after somedays use.
So if you think I will visit the person who sold me this faulty product then trust me it won't gonna work because he will say I told you to check the product before buying and purchase after full satisfaction and you checked this product earlier so its not my problem if you are getting problem in this handset.
So gyus plz trust this words they are real because I already suffered from this.
If you have trust on me then don't buy second hand electronic products. It will waste your precious money and time too.
