Zogulitsa zake zidalengeza kubwera kwa mapangidwe amtundu wa mahedifoni omwe amakhala opanda zingwe komanso anzeru.

R&D yozikidwa paukadaulo sidzasiyidwa ndi nthawi.Yison yakhala ikuyenda ndi nthawi ndikuyambitsa zida zake zomvera opanda zingwe ndikupanga kusintha kwaukadaulo nthawi zonse kuti ikhale patsogolo pamakampani.
