Samsung Galaxy J5 (2017) starts receiving Android 8.1 Oreo update
For the time being, the update is limited to Galaxy J5 (2017) users in Poland, which suggests that this is just a trial. Even so, a global rollout is to be expected in the coming weeks, so if you're using the Galaxy J5 (2017), you can be sure that you'll be getting Android 8.1 Oreo very soon.
Unlike some other mid-range Samsung smartphones, the Galaxy J5 (2017) will be updated directly to Android 8.1 Oreo. The software version that you should be looking for if you're located in Poland is J530FXXU2BRH5, but make sure you have enough storage on your phone before updating.
We still don't know what security patch it brings and what other changes it brings, so let us know in the comments if you've already received the update.
