More than the 7.1.2 update, I hope they get the 8.0 update out in time. Android 7.1.1 and 7.1.2 have some stupid bugs in fairly simple features, and while 7.1.2 ironed out one basic bug, it brought in one of its own. For example, Scheduled DND did not work in 7.1.1 (started but did not switch off as per schedule), while in 7.1.2 the DND bug was sorted but there was a stupid 'HD' notification that the user is stuck with if you use a 4G sim.
As far as I know, Oreo is free of these basic bugs.
The Billion Capture+ seems to have boosted Smartron's sales, so hopefully their support services will be boosted.
