Wifi doesnt turn on and data "sleeps" when lock phone. Kernel issue?

Flashed all recommended kernel yet still same problem. Even tried the MIUI.TW version and his recommended kernel didn't help either. (Adam's, Chronic, etc.)

What firmware or baseband were you on when you flashed that MIUI.EU? If you remember.

Thanks.

I flashed MIUI.EU a couple of months back with whatever kernel/baseband it came with... maybe the current version is buggy. There are releases every week, so do check back if they've improved it.

can't seem to have good battery life even though using alucard kernel.

What do you meant by good? 8hours of SOT?

The most i ever squeezed from my S4 is 5Hrs SOT with around 18Hrs standby time.

Undervolt more

4 hours is good enough for me.

don't dare to undervolt, worried motherboard rosak. had a bad experience once.

S4 chipset (i9505) proved to be the most reliable hardware yet to tolerate with undervolting. Ive tried it myself.

If youre concern your hardware might go faulty. Drop by minimum value only, do a test for 2 days 2 cycle charge.

My S4 Pure stock ever squeeze 4hours SOT

-25 should be fine...

I am comfortable by -50, i tried -75, guess what, it still boots and runs fine Damn nice phone we have here

But then i reverted to -50 since my brother use it for play games

The most i went to for my S3 was -50.. anything more than that my S3 will go crazy...

Lollipop 5.0 by end of 2015?

That is because of Exynos chipset is not over/underclock friendly. Samsung closed their source for Exynos that is why it is hard for developers to develop good kernels. Blame samsung, i9500 also less custom kernel because samsung did not open their source for Exynos until now

End of 2014

Wrongly read tu

ya.. end 2014..type to fast..

Keeping my fingers crossed.

Year end. Hope I haven't changed my phone by then.

Again Samsung is using it's very old trick for news announcement, just wondering is there a team of people being employ to make up the news?

Latest was S4 will go straight to 5.0!!!!!!
