It sure looks like the Z10 Pro Max was released to market in a hurry.
Several features, like backup, were not even implemented, other features have proven to be poorly implemented/tested.
Why? Formuler is bringing too many different products on too many different platforms to the market simultaneously with a too small team of staff (developers, test, quality assurance, etc.) and poor processes if you ask me.
Maybe they are scrambling for money to keep the operation running, and therefore need the cashflow, hence bring products to market asap or rather as soon as is inappropriate.
But this is just my speculative opinion.
