Need ROM for my Stock 4.3 Jelly Bean i9300 - Galaxy S III Q&A, Help & Troubleshooting

Hey guys, so I finally got my hands on S3 and the Stock ROM on this is 4.3 and so out-dated now and it lags when I install many apps. I was planning on installing CM 11 official but it has got some bugs. Can someone please suggest a stable ROM without any bugs and good battery life? Lollipop or Kit-Kat whatever ROM you think is great.

<b>Background:</b><br />
Due to lack of official maintainer for i9300 device for CyanogenMod. I, together with @Moster2 decided that we will work unofficially on i9300 device tree for CM12, to bring Lollipop goodness to our beloved Galaxy S3.<br />
All builds provided in this thread are <b>UNOFFICIAL</b>, which means that:<br />
- There is no official support for i9300<br />
- There are no OTAs available<br />
- There are no automated "nightglies"<br />
<br />
At some point, we definitely will try to make proper pull requests, and maybe even support CM12 officially, but at the moment this project is in WIP - Work-In-Progress state, and many things are still broken/unusable. Until we finish, all builds are unofficial, and proper device support is not finished yet.<br />
<br />
At the moment, this project is considered: <b><font color="green">BETA</font></b>. All core functions <b>should work</b>, ROM <b>shouldn't have any critical issues</b>, but it's <b>still not ready to mark as stable</b>. However, it <b>should work properly as daily driver</b>.<br />
<br />
<b><font color="red">Please refrain from talking about other kernels than stock. We can't track every kernel and it's problems, hence, you're using other kernels at your own risk. Please don't report bugs while you're using custom kernels.</font></b><br />

I think that every ROM including factory stock will have one or two bugs.
However, the three ROMs that I like most ATM are:
DN4 KK 4.4.4 based (do make sure to upgrade to Boeffla 7.6 kernel) - no very recent updates but Lollipop UI mod is available in the Themes section (IMO the ROM performs better without it) For me this has been the most solid KK 4.4.4 ROM
Amcha v6.10 - KK4.4.4 - a great ROM all round IMO based on S3 LTE firmware
Blekota Note 4 lite also KK 4.4.4 based - very good ROM with Lollipop UI, hints of S6 and pretty frequent updates

---

Try this one -
[ROM][GT-I9300][KK 4.4.4]?S5 Sensation ROM™ v11.0?[AROMA][OTA][MAY05,2015] - excellent rom
or qaraqumus ROMs (4.3 or 4.4)
You won't regret...

Try ArchiDroid...

Hi,
After 15 month of experience, what I can higly recommend to you is ArchiDroid. This soft has two versions: AD 1.X (based on stock Android 4.3) and AD 2.X (3.X actually, based on pure CM 12 with magnificent speed & fluidity optimizations). Today a STABLE version of the former one is going to be released, however experimental version which has beeing developed for a few months is far more stable than most LP based ROMs. So you can choose between Android 4.3 and 5.1.1. Want KitKat CM 11 ? You can also have it - you need to download STABLE version of ArchDroid 3.0.2 from the end of 2014. It is not updated any more and got an annoying bug from google (constant FC of Google Play Services app) nowdays, but you can easily find a solution within following links.
Why ArchiDroid ? It's developer put utmost pressure on reliability and quality. No compromises. This is the reason of creation of two version of his soft. Version 1.X is best when your highest priority is compatibility (for example BT headsets), stability and battery. Version 2.X is demon of speed. Beleve me - I used version 1.X quite a long time, being accustomed to stock interface and not so keen on big experiments. When I finally flashed version 2.X, the difference with fluidity and smoothness was so great... I use this version till this moment and prepare to switch to Lollipop (AD 3.1 STABLE). This version is claimed by his creator to be even faster and smoother than KK version (3.0.2). This soft is really stable, fast and battery friendly. Many optimizations means for example, that you can forgot about ads - ad blocking is just implemented in ArchiDroid. What else - using my mobile with some tuning (tasker, greenify, lux) and not gaming - just internet, mail, chat, music - I have everage SOT between 3,5 and 5 h. With great speed of this soft (no lags and difference in speed after half a year w/o reflashing)...
Aha, more than year before, hesitating which ROM will be the best choice for me, I tested as far as I remember 3 or 4 best ranked ROMs. And decided to choose AD - with no doubts.
Here you have the link to AD 2.X (3.X) thread. In a few post at the beginning you will find FAQ Q/A post - read it, it's worth it.

good luck !

The best one is Archidroid 3.X . It's fast,light and has many optimizations and far more stable than many LP roms.

HeartBrake, Did you try any of the ROM's mentioned here or other. I am also in a similar situation and landed upon this thread. I have recently rooted my Galaxy S3 I9300, and currently have 4.3. I am also looking for a ROM which will give me good battery life and better connectivity. I am facing mobile connectivity issues frequently nowadays.

---

What's the main bug with Archidroid 2.x? I'm using Archidroi 1.x at the moment but fancy a play with an AOSP rom. Can it be used on an unrooted phone? I have one phone rooted, but need an unrooted phone for Barclays mobile banking app.
