If I may I find that some Roms have a noise while using headphones in call. I noticed in purity and cm11. Noise is gone in 4.4.4 stock unless opening hangouts (only app I tested with). I also find the call quality to be less and more dropped calls on cm11. I have been on cm11 for a while and before that purity. I haven't tested many Roms.
[Nexus 4 General] showstopper1:
It has something to do with kernel mahdi s a bit slow as it s packed with features but with some simple tweaks with my favorite kernel the ROM flies.

Ls is the fastest of all though an amazing ROM.

Slim laggy and slow... L O L :D

This is a very foolish and silly thread l am going to stop there
[Nexus 4 General] vfdb:
lol slim is not slow or laggy
[Nexus 4 General] kalpik:
Yeah, too bad I don't have any way to quantify slow or fast. Only place I notice it is that the keyboard gets laggy in the slow ROMs :(
[Nexus 4 General] Planterz:
Some ROMs by default have different animation scale settings (in developer options). Default stock is 1.0x, but I've seen some ROMs that 0.75x or 0.50x as their default. This can make certain ROMs feel faster "out of the box".

I've tried maybe 20-25 different Nexus 4 ROMs in the past few weeks, and frankly none of them have felt slow or laggy, and I've never even tried switching to ART.
[Nexus 4 General] kalpik:
Yep, but I always set animation scale at 1x. Also, the lag is evident in opening the recents menu, and typing on keyboard. Even on google keyboard, if you have haptic enabled, you can feel that sometimes the keys lag, and sometimes the haptic feedback lags.

Which slimkat build number did you test ? (and same questions applies for other roms)

How did you test it ? MultiRom ? Or Clean install after wiping the device ?

I personnally use Slim roms since 3.0, and didn't feel lags, especially on my Nexus 4

(it's laggy in fact on my Nexus S, but, not the same hardware !).

What a pity for a recognized contributor to provide so false informations.
[Nexus 4 General] kalpik:
Latest version of all ROMs. Clean installs. No multirom. I'm sorry if people can't corroborate my findings. Guess I'm far too much sensitive to lags, than most other people ;)

I am on latest Mahdi and experiencing the very same LAG you were talking about. Swiftkey behaves absolutely erratic.

Thought of trying to SLIMKAT. After reading the post, I am puzzled . Love many of the features of Mahdi. Been with it

for more than 6 months.

I'm currently using the ROM in my signature. It may be placebo, but this ROM is blazing fast. If you've time, just try it ;) before i was on Mahdi too, but as said before, it became more and more unstable :(
[Nexus 4 General] Flipz77:
Something you shouldn't have been doing for at least one year, TITS (that is to say) since KK was released.

True performance is on ART. If someone wants to stick with the old fart for xposed it makes sense, but one can't judge a ROM basing on keyboard responsiveness.

Time to start a fresh with lollipop. I don't remember when I clean flashed a factory image and all the data partitions last!
[Nexus 4 General] kalpik:
Found another way to reproduce how I classify ROMs as fast and slow. In a slow ROM, do a clean flash, and when entering your wifi password, if you tap the keys really fast on google keyboard, you'll notice that it will lag, and the vibration will lag too. This lag isn't present in fast ROMs.

[Nexus 4 General] PsychoAssasin:
Maybe you dont perceive the differences, but others do.

Not every thread needs to talk about science and numbers.

On topic. I found C-rom 7.1 to be the smoothest ive tried and best on battery for me. Havent been able to find anything as good on those fronts since development ended sadly. Its still a very good and feature packed rom to date though, and im going to be flashing it back tonight.

crDroid is very Fast/Smooth ROMs.
[Nexus 4 General] leiros:
While I do not think that Slim is a slow rom (Still on the early 4.3 version), I do agree that slim does lag with swiftkey and emojis, also trying to access emojis in the facebook messenger app.
[Nexus 4 General] shaggydiamond:
I personally think the 4.3 custom rom days were much better.

4.4 roms always felt slow and buggy to me.
[Nexus 4 General] zephyr79:
I'm not too sure if I agree, one thing I will say this is only in my own experience and don't wish to tread on anyone's feet in that 4.3 for me at least had much better battery life, maybe its all in my head who knows? :confused:

B16 L Port + Adreno drivers+ Hellscore B63 the Fastest of all.. A lil less than Velocity. :p :D
[Nexus 4 General] imperator01:
Guys, I own two n4,one is stock rooted and one is on Lolipop now.

Believe what you want, but custom kitkat roms are not faster or smother than stock kitkat rom.

I did some comparison test in scrolling and app opening, and I couldn't spot any difference.

Maybe if I had a high speed camera and record the comparison I did, maybe in slow motion you could see one being faster than the other, so we are

talking about milliseconds.

Sometimes the stock kitkat on dalvik beats custom kitkat rom on art in app opening speed.
[Nexus 4 General] Popo001:
The difference with ART on kitkat is more about scrolling rather than time to open an app which is almost similar (I repeat : in kitkat).

However, for a same rom, I always see a difference in scrolling, it's definitively smoother with ART, it's obvious in Google+ or Facebook apps.
[Nexus 4 General] vampire36:
Try velocity for once...

Would change your perception guaranteed...

[ONE Q&A, Help & Troubleshooting] kynx:
This is my first post, please be kind. I really didn't want to be "that guy" and post a thread like this... but afters weeks of searching multiple forums (including xda), googling, testing, contacted game dev support, etc... I find myself desperate enough to create a thread about the compatibility of one (notoriously stubborn) game and CM11 Nightlies. I believe this is the only community that could possibly shed some light on the issue.

Game: Puzzle and Dragons (North American version)

ROM(s): Any ROM based on CM11 with nightly changes from September on.

Result: The game will go into a data download loop at first load, and/or FC after initial data download.

I'll try to rattle off all the details I've come across in my research. Puzzle and Dragons (which will be referred to as PAD from here on) will not run if it detects Xposed, I acknowledge this and it is unrelated to this specific issue. The japanese version of PAD also does not run if it detects root, certain build.prop values, and also had a data download loop bug which was related to Date/Time/Timezone. Also unrelated, as my problem is with the less-strict North American version.

I have flashed countless CM11 based ROMs and have determined that there was something changed in the nightly commits starting in September that is causing the problem. Every instance I've found of a user posting about this has reverted back to previous builds, been ignored, told the game developer must fix (which I happen to agree with), etc. I'm not really looking for a fix so much as trying to understand the change that is causing the issue and whether I should keep my eye on the game developer's updates or on the CM11 nightlies, and what to look for. The reason why I have been trying so hard to resolve this, and the reason why I've posted this in the OnePlus forums specifically is because I have one of the OPOs that has very bad touch screen issues and I have been trying to run the latest and greatest fixes for the touchscreen. I am hoping that this community would be less likely to give me the lecture about running "nightly, unstable builds and expecting everything to work". Unfortunately - PAD is the one stupid game that I play on my phone and I'm embarrassed to admit that I've put far too much time into it.

TLDR: I have an embarrassing game addiction, bad touchscreen, and a need to understand things.
[ONE Q&A, Help & Troubleshooting] kynx:
Thread was ignored but I figured I'd add more information for any of the others in my situation that may be googling their hearts out, as I have been.

The bug in PAD is present on the official 38R OTA update from OnePlus. I have contacted the game developers again in hopes that they will recognize the issue now that it is present on a stock, manufacturer provided ROM.

Could anybody using stock rom (e.g. 44S) feedback to Gungho? Since CM11S is the stock rom for Oneplus One, Gungho might try to support it......
[ONE Q&A, Help & Troubleshooting] mrpitou:
some people already did the feedback to gungho stating they have the 44S which is the official ROM. They answered the same noobish thing ...

If you are not aware, there's a fix allowing you to play PAD even with a 38R+ version or any other ROM :

get the libc.so from a 33R version (from /system/lib) and copy it over your version from the 44S for example, and PAD will run ... BUT you will lose the sensors like screen rotation ...

I tried 44S and Paranoid Android 4.6 beta 3 and it is the same ... I don't know if it is a bug in the AOSP since PA is not CM based anymore ...

so its still not fixable ? even after all those updates of pad ?

Hello,

A complete fix has been found 3 days ago, you have to get the libc.so from slimsaber.

Hi,

I found that upgrading my CM11 nightly to CM12 nightly solves this problem, maybe for those using CM 11S it also works. But DON'T USE CMupdater to upgrade, because you also have to upgrade gapps at the same time, so use recovery to flash both CM12 and gapps-lp before reboot.

okay basically I installed viper rom, everything is working fine, however the moment i turn the phone off and back on it hangs on the htc logo with the red text at the bottom. The strange thing is, If I press any volume buttons I can hear the phone make the sounds and everything, as if the phone is actually on in the background? Can anyone please help me out with this?

The only way I manage to get out of this issue is to install the rom again, and just never really switch the phone off?

one more thing, can I ask what are the full requirements that you need for isntalling the viper rom? unlocked bootloader and rooted and a custom recovery? or do I also need the s-off and the supercid and all that stuff?
[One (M8) Q&A, Help & Troubleshooting] BerndM14:
What version firmware are you running? If you installed the latest 2.xx.xxx.x capable Viper ROMs on a 1.xx.xxx.x firmware then you'll have boot up problems, it can take up to 10minutes or so to boot up. If you're still on 1.xx.xxx.x update your firmware.

[One (M8) Q&A, Help & Troubleshooting] BerndM14:
Yeah that just pretty much confirms you flashed a 2.22.xxx.x based Viper ROM, but it doesn't tells us what you ran on before you flashed the ROM.

Do you have adb installed on your PC? If not get it from mini-sdk there. You can just extract it to c:\mini-sdk . Open command prompt and type cd /d c:\mini-sdk OR just go to that folder hold shift and right click then select "Open command prompt here".

Make sure you have USB Debugging enabled on your device. Reboot your device into bootloader mode. Connect your phone to your PC and in the command prompt type:

fastboot devices

To make sure your device is connected, it should show you your device's serial number.

Next type:

fastboot getvar all

Paste the output from that command in your next post BUT MAKE SURE YOU REMOVE THE IMEI AND SERIAL NUMBER IT'S PERSONAL INFO

[One (M8) Q&A, Help & Troubleshooting] BerndM14:
Thought it might have been so. So you still ARE on 1.54.401.5/10 as your bootloader 3.16 is still from the 4.4.2 1.54.xxx.x. It changes to 3.18 once you update to 4.4.3. So you need to update your firmware.

You could either go back to stock, you can get a backup from COLLECTION of Stock backup's Instructions on how to restore it can be found in the first 2 posts of that thread as well. The stock recovery itself is also there.

HTC One firmware collection for different CID/MID | 2.22.1540.3 Mike1986 also has a very good tutorial on how to flash firmware on there.

[One (M8) Q&A, Help & Troubleshooting] BerndM14:
Some of it you won't be able to reset tampered flags etc as you're not S-OFF.

Going back to stock:

1) Download nandroid backup from thread I linked to(Collection)

2) Flash custom recovery, I take it you already have one seeing as you have the red text and bottom. Just make sure you download and flash a custom recovery applicable to the nandroid you're downloading. If it says "TWRP" then flash TWRP, if it's Philz then flash Philz.

3) Unzip the nandroid download into the folder for your backup on your device. Again this information is in post 2 on the thread I linked to. Else just create a backup of "boot" alone and it'll create the directory path for your backups on your device. Unzip the nandroid and place it in there.

5) Boot into custom recovery and Restore nandroid backup.

6) Flash stock recovery. Boot into bootloader if you're not already there - fastboot flash recovery recovery.img you do have adb/fastboot now, just make sure the recovery.img file is in your adb folder and open command in there like before(for getvar).

7) Perhaps not necessary but can do it anyways - fastboot erase cache

8) Reboot device - fastboot reboot

9) Accept prompt for OTA update, install and your firmware is updated.

Done.

Additionally for you if you want:

10) Flash TWRP/Philz recovery back to phone.

11) Flash Viper ROM

First boot up will take a couple of mins or so to setup, afterwards it'll be fine.

there was a slight delay, so it actually disconnected about the time I hit the button. sometimes the call would answer instead of dropping, depending on which button was hit.
