RFD Nexus 4 settings Kernel Custom Rom Screen Color Calibration

Filed under: Uncategorized — Tags: , , — heredago @ 14:14

Well I am about to sell my N4 today regrettably, but over the short period of time I’ve had it I will post a quick summary of what to do to get the most out of your N4 – this only applies to people who are willing to root and unlock the bootloader on the device:

– Install a custom ROM of your choice (I had CyanogenMOD 10.1)
– Download and flash faux123 kernel
– Purchase the faux123 kernel Enhancement Project app for ~$4 CDN
– Use these kernel settings with the app:

CPU: Max clock 1.134 GHZ, Min Clock 384mhz; CPU governor: intellidemand, mpdecision OFF, Snake Charmer ON
Voltage: -100mV across the board (you should be able to push this further – inch lower and lower to the most stable setting)
Governor: Up Threshold 75, Boost 0, Two Phase 702000, LMF Max 1134000, Sampling Rate 50000, Optimal Freq 594000, Synchro Freq 918000; CPU Eco Mode ON
GPU: Governor: ondemand, GPU Clock 400mhz, Vsync Toggle ON
IOSCHED: Scheduler: fiops, Readahead size 2048
Misc: Dynamic File Sync ON, TCP Congestion westwood
Vibration: (your choice), mine is at 80%
Screen: R: 255, G: 255, B: 255; Gamma Amp 0: 17, 15, 20; Gamma Amp 1: 1, 2, 3

Now I know that was a lot of ***** , but with these settings it makes the N4 a perfect device, really… the screen is now not washed out and is close to near identical to the iPhone 5 calibrated screen in terms of colour reproduction… no joke. 

The battery life with these settings are amazing. The battery % just won’t go down when I expect it to, and it really holds up with these settings. Personally was able to get over 4 hours (almost 5) with just screen time ON alone. This is with Gmail Push, Wifi on Sleep OFF, auto brightness ON. A member on XDA was able to get almost 6 hours (5h 50 min) screen time ON with these settings. 

These settings are not my original ones and are all on XDA, but shared here as a concise summary. I encourage everyone to try these out as it really brings out the max potential of the phone. Makes the N4 truly a worthy device to have with the new amazing battery life and corrects the crap screen calibration out of the box.
