Hi k3 experts.

I am using my k3 for two months now. Still using stockrom.
It is a AP new set bought from 1gadget online Lelong
I didn't change the ROM cos I thought it should be good enough. But sadly no, these are my problems:

1. Keyboard slow or non responsive, quite frequent.
When I encounter this, I had to clear all other apps from task. If it doesn't work, I had to screen off and on to make it work.

2. Night mode
I have a habit of surfing before sleep, so I use the lowest brightness and night mode. But very often, the brightness will toggle brighter suddenly ..and I can't readjust back. It will go back to my preferred brightness after a while .like a spoilt kid temper...

3. Wifi speed problems
What I hated the most is this. The speed of surfing, facebook and other apps that uses wifi ... Is simply terrible. It is as slow as a turtle, even though I am using 8mb streamyx and having at least 3 bars signal. It is not my wifi problem cos my other phones, tablet, PC has no problem of slow wifi speed at all. The weird thing is if I disabled wifi and use my 4g mobile data, it is much faster like any normal phone ... Really don't understand what's wrong. I tried everything

4. Running more than 4 basic apps like phone book, facebook, Gmail, WhatsApp
The phone becomes laggy and sometimes hang a little, which I had to screen on and off to get them working. Because of this, I had to keep clearing the tasks and apps running in the background

That said. Any recommendation the best ROM and steps I can changed to? To resolve my problems.

I am using k3-50-t3s now

Thanks!

Just to add.
I deleted facebook and all non essential apps.
I also ensure all apps notifications to be unchecked so there isn't any notifications from non essential . Only WhatsApp and Gmail has normal notifications.

I also use greenify every day to clear and force close apps...to hibernate

No effect or improvement. quite sad.

Thanks for your reply. I tried the whole night trying to root it first, but it wasn't successful. After when i enter the last step to fastboot reboot recovery, cmd just stuck at "waiting for device".

Any tips? I suspect it is because mine is already marshmallow...so it's more difficult?

There are so many different guides, row, ROM, flashing method, rooting method, I am so confused.

thanks bro, great links.
Rooted and installed twrp. Your advice and links much more easier to understand.

accidently forgotten to backup hehehe, but luckily downloaded a row s427, going to test soon.

hahaha. so many different ways of flashing..
CWM la, root first la, OTA, different flash tool, different rom, got ROW, got DEV rom etc.

The first post is also not very clear for newbie like me.
luckily we have u!

Hi guys,

Thinking of upgrading from note3 to note5.

I quite sick of this k3 which is rather laggy when typing or browsing. Always have to off screen and on back to refresh (ramissue maybe). Even Facebook app also cannot work. Can hang.

These issues happen whether stock ROM or custom.

Any k5 users met such issue? If not I will buy.

OK I will try mod the k3 with ur suggestions after I buy the new k5.

I didn't try changing custom ROM again cos quite a hassle to trial and error which is troublesome.
Usually I don't root. But I moddfed k3 cos the stock is so sucky.
Didn't expect Lenovo QC so bad now.
My previous 1gb ram a850 didn't have such problems before.

Purchased a K5 note from gemfive but received a lemon unit that drain battery from 100 to 0 within 1 hour of NOT USING.

Now have to wait for customer service email reply during weekday.
zzzzzz.
