I noticed that when there are many apps open, launching the camera app causes all apps in memory to be purged...
Yeah, the camera app is rather inefficient. They need to fix it up big time.
Another bug too. While charging your phone overnight, sometimes there is this 'system memory reset log' which purges all apps running in memory. issue still there in 9.2.1
Where would I find this? I can check if fixed in 9.3 for you. My phone is a 6S+, but I doubt that will make a difference.

Settings / Privacy / Diagnostics & Usage / Diagnostics & Data
check for any logs with 'SystemMemoryReset'
are apps reloading often for you? do u close background apps?
We need 4GB RAM! 2GB is not enough!
Gosh, Apple!
