Amazon has quietly updated its Fire HD 10 tablet, bumping the 32GB model from 3GB to 4GB of RAM and increasing the price by $15. The 64GB model remains at 3GB of RAM.

The upgraded device now ships for £149.99 in the UK (equivalent to $154.99), while the older configuration is still available for £139.99 ($139.99).

Other specs remain unchanged, including a 10.1-inch display with a resolution of 1,920 x 1,200 pixels, a 2GHz eight-core processor, and an expandable storage option through microSD cards. The battery life is still impressive at 13 hours.

Ads on the lock screen can be removed for a one-off fee, but the updated model has only been released with ads enabled.
