Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

Your right, my experience doesn't tell the whole story for everyone. I am running the newest nightly on two 32gb wifi only Nexus 7's both with M-kernel.

Both have the newest bootloader 4.18 and TWRP 2.4.4.0

Maybe it is a hardware difference or problem?

[Nexus 7 Original Development] Tone_Capone:
I'm not running into any issues like the ones you are describing. The only times I have any lag is right after boot, but after a minute and everything sets in the tablet runs smooth as butter, and that is with only 2 cores running.

I'm not sure what to tell you, perhaps the Google Currents bug is effecting you more than others. I'd look to see what apps are holding the most ram or perhaps Better Battery Stats could help find your memory leaks.

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

I having issues with system function lag as well. 1+sec for the app drawer to load, 2+ for the home screen to load after pressing the home button, and general stuttering. I am on the latest boot loader, latest TWRP, full wipe(minus SD) before installing. Running with frankcos latest. Things are smoothing out as time goes on, but I still feel the clunk.

Edit: forgot to mention, I'm running on interactive governor with noop as my scheduler.

This is my first post in this thread and I'm sorry that I'm QQin. I am loving the ROM, even with a hair of lag. The features and customization well make up for the lag, and I'll continue to use it regardless. Thank you for your time and making this.

@nickmv Exactly the same with me. I too thought it might be in part my Nexus 4 comparison. I've already returned to stock already and it's a LOT faster. No idea why some people are finding this and others are finding it smooth but it's a pain, hate being limited to stock!

Think I'll maybe wait till at least the next release before reflashing, pray it goes to plan then.

Nfc no idea if it works I have only used once. Logs and I will try but I can't test. I know s beam is weird try a third party app.

Lag, I'm sure this is one of the faster n7 Roms can't comment on 4.1 I haven't used in months. If you can provide some numerical evidence. The best is to run adb shell mircobench that's Google internal benchmark which I use for testing. Cf bench and antutu are also good. I can run builds with different optimizations if you guys want to compare but I don't have time to test personally. I do know 4.1 was faster though

Translation for pa prefs I merged a few days ago should be in the next build.

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

OK I'm going to do a clean wipe, only install antutu and do a few benchmarks. And I'll also record a video of me opening app drawer and various apps, returning home, to show the lag I'm experiencing.

Its strange only 4 of us so far are experiencing this and many other people are not. I wonder if there's something us 4 have in common... Let's see, I'm running the latest twrp, with multirom unbuntu, but I'm going to delete because I never use. I use the stock PA kernel. I'm on old boot loader. Not very many apps installed....

I switched to franco kernel insted of stock pa becouse oft better battery life. But the issue is the same with pa stock kernel so i think Franco kernel is fine and dosent procedure this issues.

Well it can use wifi direct and bluetooth for the file transfer.
[Nexus 7 Original Development] Tone_Capone:
If that doesn't fix it i would use the Nexus Root Toolkit to flash the tablet back to stock, lock the bootloader, and start from scratch. Did you use the latest image of TWRP when flashing from 4.1.2 to 4.2.2? If you weren't your file system may be compromised. Starting from scratch should fix the issue.

The discard flag is I'm my ram disk however I have noticed that it helps especially of you transfer large files in your n7 often, so it's worth a try it helps almost as much as flashing the factory images. It also helps Linux users so it's not a placebo

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

If I understand it right then yes, you're correct. The NFC is simply used for initial pairing and then sending the file share request which initiates Bluetooth. The actual file transfer is done via Bluetooth as the transfer rate for NFC isn't sufficient for this. I read that here on xda I think in the One X forum but I couldn't find the post. I guess if your Bluetooth is FUBAR you'll have problems transferring data with it.

I think you're spot on.

Ok guys im going to do do a performance comparison, the builds will be named 1,2,etc to avoid biased. Im going to do at least 4.

My preferred benchmarks are cf-bench and antutu. Ideally on pref romance governor but as long as you list what you used its fine. When you have done that test bluetooth I know one of the optimizations broke it but dont know which one

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

No, SOME nexus 7s are affected. It depends on your storage chip. I can't remember but I think the Samsung chips are the ones needing trimming. All 32GBs are okay ASFAIK. Google set it up so the discard option is ignored if you don't have an affected chip, even though it is enabled in ram disk for all.

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

Just to add my two cents here. You should know that if the partitions are mounted with the discard flag, the fstrim utility doesn't do anything. The partition is already trimmed as files are deleted.

That said, I specifically remount with nodiscard and then have this tool run nightly instead. As a Linux user, my experience with ext4 in combination with my Samsung 830, Samsung 840, Kingston HyperV 3k, and Mushkin Atlas are all slightly slowed by mounting with discard.

Of course this only occurs when you delete files or space is somehow otherwise freed, but the delay was noticeable and the time command confirmed (timing the deletes was actually unnecessary as the delay was that significant). But what TRIM does is zeros out the block so that it can be written again. If the block is not zeroed the controller has to zero first before writing data. It is not like traditional rotational media where a used block can be directly overwritten.

Now I am not sure in what ways the nature of emmc differs from traditional desktop media, and I really haven't done any comparisons between the use of discard vs batch fstrim jobs. But this is just a habit that Linux has put me in.

If you can find the fstrim binary, you can have it simply run with cron. There are instructions somewhere on these forums about how to install cron to your device. Or you can use the cron application from the play store... though if you are going to go that route you might as well use the fstrim application from the play store.

Maybe that was more like six or seven cents I threw in there.
[Nexus 7 Original Development] aaronpoweruser:
Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

Anyone as long as they provide consistent data

The memory emmc chip is wired. So the discard flag is ignored if the chip feels it doesn't need it, so fstrim helps talk to matlic about it he is more kernel oriented. I personally find it to help

At a guess it's probably because a lot of people are just blindly updating via the GooManager update notification without coming into this thread to see what it's for.

Looking at the download count at http://goo.im/devs/paranoidandroid/roms/grouper/butter it's definitely heading that way.

Re: PARANOIDANDROID 3.1 nightly(03-02) (4.2.2) | Hybrid, Pie, Per App Color

Not sure when I'll have time to flash them all but I'll download them all today so I have them. How does the following sound:

- Flash each ROM with no gapps, doing full wipes each time.

- Leave off for 5 mins. Power on, leave on for 10 mins.

- Installing nothing but the benchmark software.

- run benchmarks.

If I can I'll do both stock and M Kernel.

Just for laughs, when you test each one, unzip one of the PA ROM zip files into a folder and see if any are faster or lag free. I noticed when unzipping a large zip file, there is intermittent lag, the unzip animation pauses and so does everything else including the charging animation on my tablet.
