How to tell if a Prime is version G1 or G2?
Hello, I have a Prime and was wondering which version I have. Is there a way to check this?

Thanks

The G2 has embossed the "G2" on the back.
Under "Help" -> Tree -> About all revisions up to and including "C" is G1.
Rev D is G2

The HW version is also output by the VERSION(2) command.

What are the advantages of the G2 anyway?

Hardwarewise:

G1 uses a 400 MHz Samsung S3C2416XH-40 (ARM926EJ core, ARMv5 architecture)
G2 uses a 528 MHz NXP i.MX 6ULL MCIMX6Y2 (Cortex A7 core, ARMv7 architecture)

G1 has 32 MB RAM, 256 MB flash
G2 has 256 MB RAM, 512 MB flash

G1 battery: 3.7V/1500mAh/5.55Wh
G2 battery: 3.7V/2000mAh/7.4Wh

Softwarewise it runs at about 3x the speed of the G1:

Also, if you buy a G2 you know you will have a more readable keyboard.
If you buy a G1, you don't know which keyboard you will have without further checking.

What do you mean "you don't know which keyboard you will have"? I have a G1. Are the keyboards made differently?

The more readable keyboard has a darker blue paint scheme, this post shows the difference:

There are two hardware declensions of the first generation (G1) Prime. Rev. A and Rev. C (there was no Rev. B that I'm aware of).

All of the Rev. A and some of the early Rev. C units had the wishy-washy, barely visible colour scheme. Later Rev. C and all Rev. D (G2) Primes have the much better contrast markings.

It's doubtful that there are still any Rev. A models on the market. There are still some Rev. C models available, notably in the Americas. If you buy one of those, you won't know what colours you're getting until you unbox the unit. If you buy a G2 (Rev. D) then you're sure to get the better colour scheme.

Amazon.co.uk still have some listings with the Rev. A model number NW280AA, so maybe! One of the listings offers a selection between "HP Prime" (NW280AA) and "HP Prime -New Model - International Pack" (G8X92AAB1S). There is a separate listing for the HP Prime G2 but about £15 to £20 more than the others (perhaps to try and shift the older models).

I wouldn’t be too sure at all, I picked up a very very cheap (brand new and boxed) Hp50g six months ago , and it turned out to be old stock that had a free 1GB MP3 player in the blister pack. (I know it was old stock because I bought the very same version several years previous to this recent one!)
The MP3 player is truly ancient compared to modern variants. The 1GB is a dead giveaway to its age.

Some stockists just stock a SKU and pay little attention to which version it is, it might have also changed retail hands several times before you buy it.

The last G1s produced had the higher-contrast keyboards but many vendors still have unsold earlier models with the lower-contrast keyboards. Unless you are dealing with a knowledgeable vendor, it's a crap shoot as to which keyboard you'll get.
