Iphone 6 + keeps crashing

Honestly wondering if anyone else use iphone 6+, toram keeps crashing every 10-30 mins in game. I can still progress a bit, but it's slow. Massive maps like einklang and venena has been making toram crash alot. My problem is that my character is locked in einklang, kind of being a dumbass, i pressed the wrong tp and went on einklang. Now, I can't even start my game because even for a sec on that cursed einklang map I crash. I could probably ask my sister to move me out of that map, but i don't know how i'll be able to progress if i keep crashing there, especially since there is also main quest too. I'm considering using an emulator, my laptop is a lenovo yoga 520, but don't know what's a good emulator to use. I'd really appreciate it if people help me with this I'll change devices to iphone 7 in probably a month but i think i'll delay my progress for a long time with that month gap especially since i'm on a new account. There's no way in hell i'll leave 100m+ worth of spina and equipment there . Please help me out, thank you so much!!!

 

I sometimes experience this when my ios alt account in on International. ^_^

 

for some reason, it's only einklang map i bug out TwT even in int it can handle it even when crashing from time to time, just not einklang.
