Both my Phone and TabA have 2GB RAM 32GB Internal + 32GB in SD, I run 2 apps Oziexplorer and NDS while on the road going Bush, when near Site NDS is turned off and a Geological App is turned on "Trilobite Solutions" , I use Ozi to log tracks from home to site and hand held GPS "early Etrex" and Trilobite on my phone while wondering around swinging the Detector, both devices will get me back to the car if needed, also carry a UHF Radio. Map storage for the 2 apps "ozi-tril" have 19GB they are stored on SD, I have no problems installing NDS and using the 2 apps.
Like you said others use there phone like a PC and have everything on them, it's a wonder the phones crash, I paid $349 for phone and $499 for the Tab, If I break the phone the Sim goes in the Tab, What is on the SD card is the same for each, soon as I walk out the door the Phone is offline " Data is turned off" as i use a prepaid system and the phone is for phone calls only.
So yes others have problems. Thxs for the help too.
