The Challenge
Electronics retailers lose millions annually when customers default on smartphone installment plans and disappear. Conventional MDM solutions are either easily bypassed by factory resetting the phone or lack automated payment schedule enforcement.
What Devsynx Built
Devsynx engineered a hardware-enforced Android MDM solution with firmware-level persistence that survives factory resets, flashes reminder notifications on delinquent accounts, and completely locks device functionality if payment milestones are missed.
