The Positivo Twist Mini S430B is a budget dual-SIM phone designed for basic use with a 4-inch display and limited specs (512MB RAM, 8GB storage). Users frequently report severe system lag, app freezing (especially WhatsApp), bootloop, device stuck at logo after updates, low battery life (6 hours typical use), touchscreen unresponsiveness, and inability to multitask or run heavier apps. The combination of Android 6.0 with only 512MB RAM creates constant stuttering and crashes. Many also face forgotten password locks, “no service” on SIM cards, Wi-Fi issues, and complete inability to boot. Flashing the official 20170213 firmware below completely restores your Twist Mini S430B, removes locks, fixes system corruption, and returns it to original condition.
