Shin Megami Tensei: Persona 3 Portable

[SNap92]

Hi guys i recently started persona 3 and I love it to death but i have a small problem it keeps crashing during my time in the tower (mostly when i walk around I don`t remember if it has happened during battle) also the frame rate during a combo attacks and persona summons drops down significantly.

Does anyone have any kind of solution for this i play the game on my tablet it`s a Samsung Galaxy Tab 4 7.0 LTE:
1.5GB RAM
1.4 GHz Cortex A7 QuadCore
and sry i can`t find the exact model of the video card it says Mali 400 MP4 but that is the video chipset i don`t know if it qualifies as the tablet`s video card

I should also mention that i am playing the game in version 1.00 not 1.01 because i am afraid that if i upgrade the problem might get worse. Will the situation resolve itself if I update the ppsspp?
