Hi, @chamis
A lot of retailers do not do warranty work unless you purchase (or are given in the deal) a warranty agreement from them but ''there is always the manufacturer's warranty'' on the product. In most cases it is for 1 year (12 months) and as you have a new model phone you should still be covered. Verify this by checking the purchase receipt for the phone. If the phone is still within the warranty period consult the warranty information contained in the documentation that came with the phone as to what you have to do to make a claim for a manufacturer's warranty repair or replacement.
If you cannot find the documentation, go online and search for ''Samsung galaxy A9 (2016) warranty '' for your location.
