Dhgate, popular seller, lists the P780 with an 8 GB ROM (meaning storage) and the P780+ with 16 GB.
Both have 2 GB RAM.
Your PC has a hard disk and it has memory.
The phone's RAM is the same exact thing as the memory on a PC.
When a phone says ROM or storage, it's like the pc hard disk (just no moving parts, it's done with chips).
The storage on the phone is divided into 4 or 5 general areas.
Please think of these areas like special folders, just like on a pc. Unlike a pc, their maximum sizes are FIXED by the factory.
Here are the storage areas -
1. Reserved space you don't see and we don't show - for all of the actual telephone radio stuff to work. Before your Lenovo can be a smartphone, it has to be a phone.
2. The Android system plus the pre-installed apps your phone had when it came out of the box. A little bit of Android is hidden in part 1, above, but most of it is in /system.
3. Separate space for your apps and the private data that goes along with ALL apps, and all of that is in /data.
4. Space for your pictures, movies, music and so forth. This goes by many names, depends on the phone.
5. Optional - an SD card that you plug in. This gets used exactly like part 4, above. You can think of it like adding a second hard disk to a pc.
The first part you don't care about.
Storage Truth shows you parts 2 and 3.
Most people here are used to the part 4 number mixing in with the part 3 number, but I think it doesn't on the Lenovo.
To see parts 4 and 5, and get the rest of your phone story,
@scary alien and I recommend another app, called DiskUsage.
You'll find it linked, along with some good explanations about Storage Truth and DiskUsage, here -

Now you know about storage and how it's like pc hard disks, and how to check it out 100%.
Let's talk about RAM, or memory.
There are no good tools to show what your phone has.
Apps ask the operating system - how much memory is there?
Depending on how you ask the operating system, or which part you ask, it gives different answers.
Plus, it has a hidden, reserved part for the hardware function, just like for storage in part 1, above.
So most people get confused or believe that they've been lied to about RAM.
Dhgate has to give refunds if specs don't match, so I would trust that your actual RAM is 2 GB, available for use after the reserved hardware, probably about 1.7 or 1.8 GB, available after Android starts, probably around 1 GB, and probably left over, free memory after your apps start running, anywhere from 150 to 400 MB, depending on your personal app use.
Android handles the RAM automatically so you don't have to worry about any of that usage.
By the way - a lot of spec sites and websites will call storage as memory.
That is silly.
Do you call your pc hard disk, "the memory?"
No. No you do not.
You call the hard disk a hard disk, and many sites selling PCs call the hard disk, storage.
Only RAM is memory.
Anyway, please check the link, read the information there, use the tools together, maybe read this post more than once to help with confusion from my bad writing style and then ask any questions.
