Saya juga mengalami hal yg sama s920 baru beli & langsung update ke versi 121 tetapi masih sering hang & restart sendiri, bagaimana dengan lenovo s920 kamu sekarang apakah masih suka restart after open lock screen?

After updatethe lates rom, make restore factory. That all. Now you can install again your app. Umtil now my s920 normal.
