[Galaxy S 4 i9505 Original Android Development] side:
Some of you may know me at S4 forums. As promised, I will support S4 for yet another year and bring up the Android Pie.

So here we are. In this thread I will give you a small bite of S4 pie.

Some of you may have some questions.... So lets get it started.

Before first boot

1) Is that AOSP ? Is that LineageOS ? What is it?

- This is 99% pure AOSP sources with some LineageOS additions under the hood in order to allow our old S4 boot the Pie.

2) Is that an Alpha-beta-gamma-etc version of Optimized LineageOS 16.0?

- Maybe... But actually no... However it will surely be the base for my OptLos16.0 releases.

3) What to expect from it?

-

NOTHING

. ITS NOT RECOMMENDED FOR DAILY USAGE.

IT'S JUST A PREVIEW

... A SMALL BITE FROM THE ANDROID 9 PIE.

4) Whats working?

- It boots and charges. Nothing else is working.

NOTHING

. The only thing you can do is explore the UI, move around and such. It's just a sneak peak.

5) Whats NOT working ?

-

EVERYTHING

. Camera, GPS, nfc, wifi, vibration....

NOTHING WORKS

.

6) Can i report bugs ?

- Hell no. There is no reason to report bugs. I know what's NOT working so I can fix it when I have time. Repeat with me...

IT'S ONLY A PREVIEW

.

7) Why did you release this, you attention whore?

- S4 is dying from one day to next. Users are kicking out their devices....Give me ONE reason to NOT release a preview... There are only a few of us left who still use S4. I want to provide all the fresh stuff I can.

I promised(https://xdaforums.com/showpost.php?p=77404240&postcount=1690) and I delivered.

8) "If JDCTeam were still active they would not let you release in such early stage"

- I know. Sorry guys. Our S4 is dying. I don't listen to "rules" when its a need.

9) Will it ever be stable?

- Yes. That's a promise.

10) So how do i install it?

- I used the latest official TWRP and simply wiped & flashed the zip. No special technique or circus.

After first boot

1) It's laggy. WTF mate?

- Of course it is. And its not Pie's fault. There is much stuff missing inside. Do not expect anything.

2) I pressed power button and it doesn't wake up

- Yes. That's what happens to old devices. Same happened to Oreo when it was first released. I will fix it soon. Relax people. Patience. Please remove and re-insert your battery again. Set the screen time-out long so you don't encounter it.

For now DO NOT LOCK / SLEEP YOUR DEVICE.

3) I had random reboot / freeze / SystemUI crash

- Yes. That's normal. Although it didn't happen to me.

4) I cant find the recents menu

- Neither did I. Since ADB is disabled for now i cant debug it. Could be launcher. Try Nova. Patience.... the best will come soon.

In conclusion

I would like to thank:

Every Optimized Lineage / CM user that is / was active at forums and pumped me up to bring Pie to S4.

Every OptLosOreo Slack member that helped me in his own way.

Every code stealer. I want you around guys.

Specially:

[MENTION=4385445]Creeper36[/MENTION] The guy under the hood who's always supporting me for 3 years now. He is back !

[MENTION=1711160]Buff99[/MENTION] My other half on optlos15.1. No buff - No RR for JF - No updated kernel.

[MENTION=7166104]Patrick x[/MENTION] The most loyal member. Been with me since day 1 of telegram.

All others from OptLosOreo Slack team especially Splesher, JMvstheworld, RuKaDa, Tim, SalimPS , Kesaras (I wont tag em to avoid spam).
