Hi sport, Called on you 'cause you da bestist ! Mobile Devices: 1) LGL83BL Nexus 4 Stylus 3, S/W Ver. L83BL10b Android Android 7.0 Build NRD90U. 2). Amazon Fire HD10 (2019) Model KFMAWI, hacked to become psuedo-standard Android using an Android Debug Bridge via "[Windows] [Tool] Fire Toolbox V22.0" from forum.xda-developers(dot)com. As such, the device reports an OS of Android Version 9 (Pie) Build PS7318. WHY DIDI I DO THIS? To have access to more than the skimpy Amazon Apps. To date, I've had no issues for months using Google Play Apps. So, here's the deal ... On both devices NPM Settings does not permit an Auto-lock beyond 2 Hours. The "Keep open indefinitely" setting forces the Vault to close immediately once minimised, or using it a single time on Chrome, or any App Login for that matter. As such, the max. time period I can keep it open is on the 2 Hour setting. My devices are never more than arms breach away, and the Lock is seldom, if ever, needed. Any help is greatly appreciated. P.S. KODOS for still kicking around ! Your pal, Art
