MCPE 1.1.5 keep crashing while playing for some minutes

Hey team. Mcpe crashing while playing for some minutes. I tried resetting the device, downgrading chunks to 8, using default skin/texture pack . Nothing of them worked. My device is S5 neo (SM-G903F) based on Exynos Octa 64 bit processor with 8 cores(1.6ghz). I would be happy for a solution thanks. Ps : my device wont even show an alertdialog when mcpe crashes.
