iphone 5s 16GB suddenly has no free memory- why?
I had about 600M free last time I checked (not long ago) - last night I got the low memory warning - was initially 30m then 15m, now zero! is this something to do with 9.0.2 which is now prompting me to install? I haven't installed as I was waiting for 9.1 (I'm still running 7.1.2 due to 8 requiring huge amounts of free memory to install).
I haven't downloaded any videos or anything else that would take a lot of memory
any insight gratefully received!
