Samsung's Galaxy J5 and J7 launched in June last year with Android 5.1 Lollipop and the ones launched today are no different, even though the latest Android 6.0 Marshmallow is now present in Samsung's Galaxy S6, S6 Edge phones and is now rolling out to Galaxy S5 handsets.
Samsung has not mentioned or given any indication on whether Android 6.0 Marshmallow will be rolled out to the new J5 and J7 devices.
In terms of display, the specifications of Galaxy J7 (2015) and Galaxy J7 (2016) are completely similar, featuring resolutions of 1920 x 1080p which are otherwise referred to as Full HD displays. The same applies to both variants of Galaxy J5 which feature HD displays with resolutions of 720 x 1280 pixels.
However, the display in Galaxy J5 is larger at 5.2-inches compared to the 5-inch display in Galaxy J5 launched last year.
Galaxy J7 2015 152.4 x 78.6 x 7.5mmGalaxy J7 2016 151.7 x 76 x 7.8mm
Galaxy J5 2015 142.1 x 71.8 x 7.9mmGalaxy J5 2016 145.8 x 72.3 x 8.1mm
The just-launched Galaxy J5 is slightly shorter but .3mm thicker than its predecessor and is slightly wider as well. On the other hand, J5 2016 is 3mm taller and negligibly thicker than its predecessor.
While J7 2016 at 170g weighs 1g less than its predecessor, J5 2016 weighs 159g compared to just 146g that its predecessor weighed.
While Galaxy J5 and J7 phones launched last year sported 2,600 mAh and 3,000 mAh batteries respectively, the ones launched this year feature more powerful ones of 3,100 mAh and 3,300 mAh ones respectively. This would mean that the new phones will last longer than the existing ones under normal usage.
Last year's Galaxy J5 came with 1.5GB of RAM and 8GB of storage coupled with a microSD card which offered up to 128GB of additional space. Samsung has decided to maintain the same configuration this time and has retained the microSD card as well.
On the other hand, Samsung has doubled the RAM in Galaxy J7 from 1.5GB to 3GB but has kept internal storage constant at 16GB. The microSD slot with additional storage option of 128GB also retains its place.
Galaxy J7 retains its camera specifications with 13MP and 5MP auto-focus ones and the rear camera in the newer version can shoot Full HD videos with resolutions of 1920 x 1080 pixels at 30 fps. Galaxy J5 also retains the same cameras as the ones launched last year.
If you are an existing user of a Galaxy J7 and want to upgrade this year, all you will get is an improved battery and double the RAM along with the same OS, display, storage, RAM and cameras. These improvements will offer you longer usage and a smoother performance.
However, aside from a powerful battery, Galaxy J5 now features a slightly larger display as well but is 13g heavier than the existing one as a result. The absence of Android 6.0 Marshmallow in both phones is probably the most disappointing factor, but we aren't sure if these phones will sport Lollipop or Marshmallow when launched in the UK.
Despite sporting an older OS in the Chinese version, both phones come with dual SIM support, 4G connectivity, Voice-over LTE functionality as well as NFC for making contactless payments.
