# Bug Report
## Problem
In low memory, and on physical device only: In my `pause` event handler, I
do `localStorage.setItem(...)` . Then in my `resume` and `deviceready` event
handlers, I do `localStorage.getItem(...)`, but the retrieved value is always
null. When using the emulator, it works as expected.
### What is expected to happen?
`localStorage.getItem()` in `resume` or `deviceready` should get back the
value that was set in `localStorage.setItem(...)` .
### What does actually happen?
`localStorage.getItem()` in those handlers just returns `null`.
## Information
This only happens on a physical device (I'm using a Pixel 2 XL). All is OK
in the emulator.
An `alert()` in the `pause` handler (briefly) shows that the value is
correctly set with `localStorage.setItem()` .
This could be related to bug # .
### Command or Code
HTML file `index.html` is:
```
<!DOCTYPE html>

<head>
<meta http-equiv="Content-Security-Policy" content="default-src *">

<script type="text/javascript" src="js/index2.js"></script>
</head>
<body>
</body>
</html>
```
JavaScript file `index2.js` is:
```
"use strict" ;
var app = {
initialize: function() {
document.addEventListener('deviceready',
this.onDeviceReady.bind(this), false);
},
onDeviceReady: async function() {
alert('ondeviceready') ;
document.addEventListener('pause', on_pause, false) ;
document.addEventListener('resume', on_resume, false) ;
let saved_state= localStorage.getItem('saved_state') ;
alert('in ondeviceready, saved_state='+saved_state) ; // is
always null here when on physical device
localStorage.removeItem('saved_state') ;
},
};
app.initialize();
function on_pause() {
localStorage.setItem('saved_state', 'test') ;
alert('end of onpause,
saved_state=['+localStorage.getItem('saved_state')+']') ;
}
function on_resume(event) {
// this never runs-- apparently resume event isn't fired
alert('in onresume,
saved_state=['+localStorage.getItem('saved_state')+']') ;
}
```
