About Samsung Galaxy J7 2017
The Samsung Galaxy J7 2017 presents a straightforward design that fits comfortably in the hand, measuring 76.4 mm wide, 151.4 mm tall and just 7.5 mm thick while weighing 170 grams. Its front is occupied by a 5.49‑inch color TN‑TFT LCD screen delivering a resolution of 720 by 1280 pixels, offering clear visuals for everyday tasks such as browsing, messaging and media playback. The device supports a single SIM card, keeping the layout simple for users who prefer one line of service.
Under the hood, the phone runs Google Android 7.0 Nougat and is equipped with 2 GB of RAM, providing enough memory for basic multitasking and app usage. Power comes from a 3300 mAh battery, which aims to sustain a full day of moderate use without needing a recharge. Together, these specifications position the Galaxy J7 2017 as a modestly sized, entry‑level smartphone focused on delivering reliable performance for essential smartphone functions.
The Samsung SM-J730K Galaxy J7 2017 TD-LTE KR upgrades the panel to an AM-OLED display measuring 5.48 inches with a Full HD 1080x1920 resolution, a step up from the base model’s TN‑TFT LCD. It runs Android 7.1.1 Nougat and is equipped with 3 GB of RAM, while the battery capacity rises to 3600 mAh. The chassis measures 74.8 × 152.5 × 8 mm and the device weighs 181 grams.
Compared with the J727U and J727R4 LTE‑A models, which retain 2 GB of RAM and the standard LCD screen, this variant offers more memory and a sharper AM‑OLED panel. It also differs from the Duos‑enabled J730F/DS and J730FM/DS versions by featuring a single SIM slot; the J730FM/DS shares the 3 GB RAM but keeps the dual‑SIM configuration and likely the LCD display, whereas the SM‑J730K combines the higher RAM with the AM‑OLED screen in a single‑SIM form factor.
