I am posting now under every Facebook post or wherever, when there is an update for Umidigi z. It can not be done so here is a bad update policy is performed.
I'm grateful if you let us know, but I'm assuming it will not be until 2018 or later. I can not understand why umi and patners do not give the source code. That would be much easier for everyone.
It is past the time to launch new updates, it is not umidigi, because this is your problem, they launch new devices and only focus on them, forget about others, it is with if they did not even exist anymore
Hi,
I'm sorry but since Marshmallow that feature is not available in any UMi/UMIDIGI smartphones - it's not enough secure. But you can find some such apps in the play store if you need that feature.
