I have upgraded my Moto G2 phone set to Lollipop version, After I did this facing issue with screen pattern lock/unlocking.
After I unlock screen, it goes lock again and this continues until I frustrated and I leave my phone untouched for sometime. Then I try after some time should be ok.
Very annoying and making life complex when desperately need to use.
Please some one share if you have face similar issue and resolved. Thanks.
