由于电池信息在更新电量信息时重画Status Icon Bar背景，将其他icon都覆盖掉，而后只画了电池图标，导致其他图片消失。
需要修改函数：
void SUBLCD_screens_hide_status_icons(void)
{
#ifdef __MMI_SUBLCD__
/*----------------------------------------------------------------*/
/* Local Variables */
/*----------------------------------------------------------------*/
GDI_HANDLE act_lcd = GDI_ERROR_HANDLE;
S32 x1, x2, y1, y2;
/*----------------------------------------------------------------*/
/* Code Body */
/*----------------------------------------------------------------*/
#ifdef __MMI_SUBLCD_SHOW_ANALOG_CLOCK__
return;
#endif
GDI_LOCK;
gdi_lcd_get_active(&act_lcd);
if (act_lcd != GDI_LCD_SUB_LCD_HANDLE)
{
UI_set_sub_LCD_graphics_context();
}
wgui_status_icon_bar_get_clip(WGUI_STATUS_ICON_BAR_SUBLCD_H_BAR, &x1, &y1, &x2, &y2);
wgui_status_icon_bar_show_sublcd_background(x1, y1, x2, y2, MMI_TRUE);
if (act_lcd == GDI_LCD_MAIN_LCD_HANDLE)
{
UI_set_main_LCD_graphics_context();
}
GDI_UNLOCK;
#endif /* __MMI_SUBLCD__ */
}
