The quality of parts in the mobile phone industry is a minefield. We procure only AAA quality parts.
Although more expensive, AAA parts have better build quality, use AAA Gorilla Glass (on screens) & last about 3-4 times longer than copy or aftermarket parts.
High warranty rates, faulty parts & quality issues relating to copy/ aftermarket parts are not worth the trouble so it’s in our best interest to procure only the best.
