Dear pcheng,
  Could you help have a test on flame with v2.0, I think both dolphin and flame have the same issue.
  Thanks.

I propose the cause is

in gaia/apps/system/js/screen_manager.js

_reconfigScreenTimeout: function scm_reconfigScreenTimeout() {
    // Remove idle timer if screen wake lock is acquired or
    // if no app has been displayed yet.
    if (this._screenWakeLocked || typeof(AppWindowManager) !== 'object' ||
        !AppWindowManager.getActiveApp()) {

"!AppWindowManager.getActiveApp()" is true when USB cable insert, and "this._setIdleTimeout(0)" let screen always lighting.

Hi Vance,
  Please ensure that don't touch anything when starting up, wait for five minutes and then insert USB cable.

I reproduced this on Flame V2.0 with following steps, but NOT on V2.1. 

STR:
0. set screen timeout to "1 minute" and set screen lock

1. reboot device    *** DO NOT do anything after startup *** 
   Device stays on lockscreen.

2. Wait for the screen time out *** DO NOT turn it off manually ***

3. Insert USB cable and wait *** DO NOT do anything *** 
   -->  You will see screen stays on lockscreen but can NOT be turned off automatically.（sreen timeout is 1 minute）


Per the steps, I think this is a minor issue.

Is it worth fixing, especially if it happens only on 2.0?
Does the screen turns off when you unplug the USB cable?

engineers in sprd don't decide whether some bugs should be fixed or not.

we try our best to fix all of them.
