1. I can see a different size memory for background for different devices (f7 65536, f6 32768...). I can't find table for all devices, so is 32768 the minium for all of them (CIQ >=2.4)?
2. How to find out about objects in background. I can see used :18920 free:9720 total:28640 but want to now what is in the 18920. I need about 11kB so have to free something.
