Introduction
This guide will tell you how to fix the OnePlus 6 or 6T alert slider from registering only 2 of the 3 positions.
The issue is that one of the sound modes of the OnePlus 6 or 6T does not get recognized by the software anymore. The device can only be set into two modes - either sound, vibrate, or silence - and the third one is not recognized.
The cause is the accumulation of dust in the slider. This prevents the slider from reaching (one of the two) outermost positions. It is possible that the slider does look clean from the outside and that the slider still moves completely to the non-working side, but that it still does not recognize it.
