[Galaxy S 4 i9500 Original Android Development] Mir Asif:
I installed this rom and here's how i did this and how this worked for me...

The first part is for those who have enough time and give attention to details, others should not waste time with the first part and jump directly to the second part.

1.Part ONE (Installation Procedure)...

I had previously updated my Galaxy S4 to stock android 5.0.1 using OTA update, this was the time when my phone was not rooted. so that means i had my baseband,modem

files and kernel etc were already updated to latest lolipop... Due to heavy samsung bloat-ware in the stock rom i rooted my phone and installed CMW recovery.[and then i

flashed Stock based (touchviz) "Prism Barebone" rom developed by devloper [MENTION=4648515]AL_IRAQI[/MENTION].. This is the most stable rom availible out there for those who prefer Touchwiz and

totally stock user-interface...] Cyanogen roms have their own uniqueness so decided to try one and i found the rom in this forum to be latest and a most stable one to

give it a try... I took a backup of "prism barebone" rom using CMW recovery and then i installed "TWRP manager" (i was not able to download TWRP manager from playstore

due to error 927 so i download it from somewhere else) and then flashed TWRP recovery (2.8.4) using this manager... Downloaded the cm-12.1-20150511UNOFFICIAL-i9500.zip

from the latest post and gApps from the first post of this thread using UC browser..(I had no issues whatsoever with downloading the files)

Rebooted into TWRP recovery and formatted all partitions except internal storage and external sdcard and then installed the rom zip and restarted (did not install gApps

yet) the phone started and i selected the language to UK English and then a prompt popped up to create Cyanogen account which i wanted to create but some error occurred

and i skipped the step.. After that i played with it to get a feel of Cynogen... and an hour or so i installed the gApps and restarted the phone and started restoring

all the apps which i had already backed up using "App_BAckup_Restore" and now here's what i experienced so far...

2. Part TWO (User Experience)...

The first things i looked for were the frequently reported audio, audio recording volume and slow camera bugs... what i found was the volume of recorded voices was

really very low, one needs to speak very close to the mic to make the recording sound louder but i found that the phone recorded the voice with the primary Mic located

at the bottom of the phone, so in this case it was different from people who say it recorded with the secondary Mic .. I didn't check any third party recording app

though...

I checked the camera and here i feel like i was a bit lucky because once i clicked the camera app, to my surprise it launched quicker than the stock one and as played

with it, closed and opened it quickly it didnt show any errors whatsoever and responded to every touch instantly until once i tried to open and close it with ninja

speed, there it showed "cannot connect camera" error but i dont thing this is going to happen in real life experience..regarding camera quality,well.. it was par with

stock one.. i mostly use "camera FV-5" and it works nicely on this rom as well.. so, no issues with this department...

I am not very fond of music but to check the audio i opened the music player and played few songs and i didn't have any problems with it... the volume was high as it is

in stock rom, voices were clear... But then i checked the ringer volume and Gosh it was almost half what i used to get on stock, this is same for notification, alarms

etc.. this is serious issue which creates a lot of inconvenience...

Checked the themes app and once i try to download more themes, CyanogenMod themes Showcase doesn't install, it freezes the playstore once i click on install button in

playstore...tried clearing data for playstore but that didn't help either.. EDIT:- it worked after few restarts....

Torch in the notification panel showed a delay of seconds on the first start but then after the first try it improved and the delay time scaled down to half a

second which is manageable...

Charging takes almost same time as it was on stock 2 hours 15 minutes to charge from 5 to 100% with screen off... i cant comment on the battery life yet...

I will come up with an update to my review after a day or two...
