Samsung Galaxy A5 (2015)

Samsung Galaxy A5's system-on chip is Qualcomm Snapdragon 410, which is a 64-bit 1.2 GHz ARM Cortex-A53 processor. The graphic processor of the phone is Adreno 306. The smartphone has 2 GB RAM and 16 GB internal storage, with support for removable MicroSD cards of up to 64 GB. The device's MicroSD card slot has been designed to allow insertion of a SIM card, and thus the A5 can also be used in Dual SIM mode.

The Samsung Galaxy A5 shifts away from the plastic design of previous phones, featuring an aluminium unibody with chamfered metal edges. While its design is almost similar to the earlier Samsung Galaxy Alpha and Samsung Galaxy Note 4, the A5 has a larger 5-inch Super AMOLED HD display compared to the 4.7-inch display of Galaxy Alpha, as well as being slimmer at 6.7 mm, becoming the thinnest Samsung smartphone at the time of release. The A5’s display features screen protection, utilizing the newer Gorilla Glass 4. The phone carries over the 13-megapixel rear camera sensor from the successful Galaxy S4, with software tweaks for sharper detail and better low-light capability. The front of the device features a new 5-megapixel camera for better detail capture, with the phone marketed towards a 'selfie' oriented younger audience.

The device runs on Google's 4.4.4 "KitKat" Android operating system out of the box, featuring the improved TouchWiz Nature UX 3.5 as well as introducing a theme suite, later made standard on newer devices. The Note 4, Note Edge, and the Galaxy A-series were the only devices to ship with this interface on Android 4.4.4. The Galaxy A5 would later receive Android 5.0.2 "Lollipop" in May 2015. Android 6.0.1 Marshmallow for the Galaxy A-series was announced in July 2016 and the devices are currently receiving the newer operating system. The OTA update also brings a slightly updated TouchWiz UI that remains largely similar to the nature UX 3.5 and 4.0 user interfaces from the Note 4 and Galaxy S5, but features newer 'squircle' icons introduced in the Note 5. This is considered to be the last major Android update for the phone, following Google and Samsung's 2-year software support policy.
