Dah agak dah..
I want to add but joytest already gave a good answer for you.

Time to flash new ROM la.. wahaha

Custom ROM may noy solving your problem but the most important is knowing what is pulling your phone
I have a friend complaint slow but after diagnose it is due to an application that installed recently taking a lot of memory to run. What I did was clean data for that apps.

anyway to restore my whatsapp conversations? that is crucial to me
but i don't want to root my phone.

hope it above 5.5inch

Whatapps conversation is stored in internal storage what you need to do is copy that folder toba location and after reinstall whatapps, you just replace with the backup copy.

Note 1 is already not convenient if note 3 over 5.5 need to carry beg all the time very troublesome

Good for some bad for some. I'm on the side that wish it bigger

experienced this in the past week.
so today all i did was discharged the battery to 0%, remove the battery for few mins n reinsert. Also replug in the usb cable to the charger, den charge the phone w/o starting it. 2 n a half hr ltr battery fully charged.
well, it seems problem solved, i hope it wont repeat history in the nxt charge cycle la

Hoping note 4 will be 6.3"

nobody care it already ...

backup
else reflash the ROM

I didn't restart also @@
yet, even on note 2 also lag
on xperia z also lag, early game when jump
then no more

continue at v31
