Answer #1
Sorry i can’t help as i don’t know anything about that phone.
But i have the same problem with my phone, the more i write, say an email and it just keeps getting slower and slower in response time.
I just put it down to my phone not having enough free memory.
But my phone is an old phone and i’m sure yours would have much more memory than mine.
Answer #2
try with factory reset
back up data before
Answer #3
I did a quick search and this may help.
