Default Low system RAM notice on Star n9770

I have an n9770, and itís been great, but recently I keep getting notices for low RAM.

I love this phone, but the low RAM makes it almost useless.

Is there a way of increasing the RAM? Can anybody give me step-by-step instructions so I donít brick the phone?

I have connected to the phone with MTK Droid Tools, but didnít press any buttons etc. as I donít know how to use, and didnít want to ROOT, as my banking app wont wonk on ROOTED phones.

I have seen a post at where a senior user claim to have repartitioned their phone, but with no model details, and I understand that these Chinese phones are very model/ROM sensitive.

Really appreciate if anyone can help

Below Iíve listed the dump from MTK Droid Tools
