The Samsung Z1 uses PLS TFT technology with its 4-inch display. The PLS technology works similar to the LG’s IPS technology; it helps in keeping the colours on display unchanged when viewed from various angles. The display has a pixel density of 233 PPI which is acceptable but not astonishing. If you are looking for HD

However, Samsung was generous enough to provide with an LED flash. A VGA camera is equipped on the front for video calls and selfies. The video recording is performed with 480p resolution at 15 frames per second on the Samsung Z1.
