OnePlus recently launched its OnePlus 6 with glass sandwich design (front-rear glass frame), but looks like the design backfired as users have reported their phone’s back panel spontaneously cracking.

Many users of the newly launched OnePlus 6 have reported that the phone’s glass back panel cracked by itself, without any drop. Users took to the discussion website Reddit to report the cracks.

Two of them reported cracks at the exact same location near the phone’s volume keys with a similar pattern. Both of the phones had official protective cases and both the users said that their phones weren’t dropped right before the cracks, however, one of the admitted to dropping the phone previously on three occasions.

Those users that have never dropped their phones once and always had them in wooden cases went through similar situation too.
