In order to unlock your tablet, you can download and install Screen Lock Bypass Pro from Google Play Store. This utility will bypass the lock screen and will allow you to reset/remove your screen lock password, pattern or PIN number. Alternatively, you will need to factory reset your device. To do this, turn off the Levono IdeaTab A2107A and press and hold the Volume Up + Power buttons. Then, release the Power button but keep the Volume Up pressed until the Android logo appears. Select Wipe Data/Factory reset and the device will be restored to its factory condition.
