Display does not dim anymore

5 replies · 4,052 views · Started 06 July 2011

Hi there,

this is my first post in this forum.

I have an E7 now for about 3 Months. Recently the 'Light time-out' stopped working, and I need to manually lock the screen with the hardware key to dim/switch off the display. I have closed all apps shown in the dialog 'Open applications' shows and also removed all widgets, but not the favourites widget.
WhatsApp is running, invisibly, in the background, but it was working before with WhatsApp.

The timeout is set to 5 secs for the light and 1 Minute for key lock.

I guess I do not need to mentioned that I also tried to reboot the phone. On my previous E71 I would also try to remove the battery for 10 mins to soft-reset the phone, well this is no longer possible on the E7.

You can see I'm rather desperate on that issue and manually locking/swithing off the display is a real hassle.

Could you give me some hints on that?

Try hard reset your phone:
*#7370#
Need to go offline first I think. Password might be: 12345 or 0000

Well, I was hoping for a more gentle method. I tried *#7780# to reset factory settings (without deleting any user data nor installed applications). However this didn't help either.

I could imagine that a single application / process in the background keeps the display active.
If there was a process list viewer and process kill utility such as JBTaskMan (for previous S60 releases) I could try to terminate some of the processes to test which one keeps the display active. However I'm not aware of such a tool.

I bought JBTaskMan for S60 5th edition, it runs but it is not usable without the soft keys available in S60 5th.
Would you have any other suggestion?

Thanks for the hints,

Those apps are either not installed nor running.

I tried JbakTaskMan as a task manager/process killer, which I bought JBakTaskMan as I was a happy user of it on my previous E71. Though it was sold for my E7, when I install it I get a not hat it is not compatible with my phone and it's not usable due to missing soft keys.

After this experience I'm reluctant to buy another TaskManager which may not work either and I haven't found a free / shareware version that I could test before buying.

Don't do a hard reset!

I found out the hard way that it messes up the Qt libraries so Ovi Store doesn't work, no matter what libraries you re-install. The only way to fix it is to re-flash the firmware yourself or send the phone to a service center.

I suggest uninstalling programs one by one to see if an errant program is hogging the screen, or tinker around by changing themes and screensavers. A cold boot could also help: turn off the phone, turn it back on and quickly hold down the power button for a few seconds until it vibrates a few times, then turn it back on again.
