Low RAM and crash
« On:January 09, 2016, 02:54:00 PM »

I had done factory reset last week. Again facing same problem: low RAM. Where has gone memory ? I'm unable to use any apps like - settings, my files, camera, image viewer, browser, whatsapp ... Everything is crashing. Only operamini is running correctly.
Is there any way to free RAM?
Please help me out.

1.
Can you please post Screenshot from Smart Manager app.

2.
After Power off (Reboot)
Check again Smart Manager

Is after Reboot same problem?
Or after Reboot you have "few minutes" normal status?



I know on my Z1...
Handset do crazy things if not enough free space...
And I can read problems also on Z3...

We need to find where exactly is not enough memory...

Btw.

You use Themes from Theme Store?

I know from bada time...
Themes are like "System Files"...
They could also consuming big RAM...

?

This is funny...

In my Log example from Z3 BOL4 I can see also only 100 MB free RAM...

?

Will check other Logs...

But for instance my Z1 COL6 has 369 MB FREE

And we all know, Z1 has only 768 MB Total... instead 1000 MB (1GB) Z3

Best Regards

Edit 1.

I had downloaded ACL only for testing purposes and tried few times for launching SHAREit. I wonder how is it possible ACL consumed 210+ mb user data.

At the moment I have ACL not installed...

If I remember correct, their is an option... in ACL.

Something like standard is as Background... or you can set ACL only start with app...

But I am at the moment busy with Here Maps maps download...

I will try later...
