Description: If the user opens the Usage app, then browses the internet, changing the current data usage values, returning to the Usage app will display a largely blank screen with only the Header and Settings 'Gear' icon displayed. If the user selects the gear icon, then dismisses the settings screen, the usage app will redraw properly Repro Steps: 1) Update a Flame to 20140908040204 2) Open the Usage app and set up a data limit. 3) Open the Browser and navigate the internet, increasing data usage. 4) Return to the Usage app Actual: Usage app is not rendered properly. Expected: Usage app is rendered properly.

I'm also unable to reproduce on 2.1 but I saw this bug on reporter's device. Marty can you do an analysis on the reproduction rate and report if there is perhaps a pre-requisite that may be missing that could be affecting this? (example: data limit set, different tracking, how many apps open, etc)

After further investigation, it appears this is a 319MB related memory issue. I was able to reproduce this bug without a WiFi or Data network connection, and opening the Camera app and taking a picture. I was NOT able to reproduce this bug at all using a device set to 512MB memory or on 2.0 (319MB and 512MB). Updated STR: 1) Update a Flame device to BuildID: 20140911064110 set to 319MB memory. 2) Open the Usage app and Set up a data alert. 3) Tap the Home button (leaving the Usage app running). 4) Open the Camera app and take a picture. 5) Tap the Home button, then tap the Usage app to re-open it. ------------------------------------------------------------------------ This issue occurred 7/7 times using these new STR on Flame Master set to 319MB memory.

Attached file patch v1.0
Hi Salva, the error is produced when the App is killed by the oom killer. On this patch, I reset the value of the location hash, because when the App is relaunched after being killed, it keeps the value of its previous execution. I'm not sure if this behaviour should be the correct, IMO when the App is relaunched, the hash should be cleared. Regards

Comment on attachment 8488567 [details] [review] patch v1.0 The patch is ok but I would prefer to take advantage of this suspend new feature and call the onhashchange handler to resume the application from the same screen it was before killed. What do you think?
