Does Locker Service work on Salesforce1 App and mobile browser

Question

Dear Salesforce Developer,

I've tested locker services on SF1 App and mobile browser. It doesn't work. So Locker service isn't supported on SF1 App and mobile browser

Sample Code:

Test.cmp

<aura:component implements="flexipage:availableForAllPageTypes" access="global" >
    <div >
        <ui:outputText aura:id="hid_redirectLbl" value="abcd"/>
    </div>
    <aura:handler name="init" value="{!this}" action="{!c.doPreInit}" /> 

</aura:component>

TestController.js

({
    doPreInit : function(component, event, helper) {
        alert(component.find("hid_redirectLbl").get('v.value'));
    }

})

Bug:

[NoErrorObjectAvailable] TypeError: A WeakMap cannot have a non-object key\

Updated: The error will be occurred on iOs version 8.1.3

The higher iOs version is OK

LS is certainly intended to work in all supported browsers which includes those you listed. Your repro case also looks legitimate. There is no open or known issue on this error message currently though. Do you have a salesforce support case open on this yet?
