Look at youtube "How To Increase RAM On Your Android Phone" or ROEHSOFT’s RAM Expander for 10$.

Please do not write in the thread about issues other than those related to this ROM.

Thank you for your understanding. Do not waste your time and others.
[LG Optimus 4X HD] kostarum:
Ok, aggred. Thanks.

I still have big problems with lag,on latest 7.1.2 ROM, but battery is good.
[LG Optimus 4X HD] csk1jw:
Please be reasonable when complaining lagginess on such an old device. The comparison should be relative to what this phone used to be. I would say the UX is on par or better than LG v20c stock JB ROM even though Nougat is more advanced than JB. I had more recent phones such as OnePlusX and BLU R1HD. It is just not possible to make this old device as snappy as those devices in 2015 and beyond due to technologies advances.
[LG Optimus 4X HD] csk1jw:
Actually, CPU & GPU are less of an issue for day-to-day phone usage. The main factor for UX snappiness is really the storage I/O, not just throughput but also latency. CPU & GPU are just good shows for benchmarking. The 1.5GHz Cortex-A9 in Tegra3 is actually more powerful than lots of low-end phones shipped in the last 2 years based on 1.2GHz Cortex-A7. Apple uses the in-house propriety NVMe interface for storage starting with IPhone 6S and onwards, while Samsung and others go for the industry UFS 2.0/2.1 standards. Modern storage I/O such as those enable very deep I/O queue and prioritization options to maximize throughput and hide latencies.
[LG Optimus 4X HD] SMaxtor:
ROM works fine for me without lags. But there is a bug with the power government. If you use "interactive", background apps lost there priority (massiv lag after display goes off). Root your phone, install no-frill from store and change your power government into "ondemand".

New build 20170502

New build is up.

Finally, I am glad to declare that I was able to fix the random apps close issues since the 1st release of Nougat-based ROM. The back-ported kernel feature from AOSP kernel-3.4 helped to root cause this. Unlike MM, Nougat requires this kernel commit to provide stack trace during SIGSEGV fault in user space. With the stack trace in logcat dump, I successfully traced back the cause of random apps close.

This is the offending Google commit that caused the random apps close.

hwui: add extension to support unpack operations in OpenGL ES 2.0

OpenGL ES 3.0+ lets us specify the row length for unpack operations
such as glTexSubImage2D(). This allows us to upload a sub-rectangle
of a texture. Also, the GL_EXT_unpack_subimage extension can also
support this feature in OpenGL ES 2.0

Change-Id: Id43c2c55c5eaefbace67087c955f0b4324fb2c35

Apparently, the GL_EXT_unpack_subimage on Tegra3 OpenGL ES 2.0 implementation does not quite work for Google's use case on Nougat. There is no need to patch vendor blobs to fix this.

Last thing to this - if the problem persists, just write me a pm with the kind of gapps you want (pico, stock, ...) and I can upload it in my dropbox and send you the link to that.

If this doesn't change anything the problem must be connected to your network / provider (and most probably is anyway, as others can download without a problem).

Wow i was actually right when i said there was too much io! I cant believe you found this! you the best!

Guys my father fried parts of p880 motherboard by "making" a charger, basically connected it to ac (he is old, 60+)... I'm ashamed of him now! The phone doesnt work ofc... I disassembled it, speaker on its own works, vibrator too... Is there a chance that the phone is repairable without changing the motherboard? You can see burn marks on 2 places. What do you think are the chips alive, can this be repaired without new motherboard? Sory for off topic but this is probably the only alive thread...
[LG Optimus 4X HD] Phil_Smith:
Imho this is waaay more effort than it's worth.

This device is really getting so old. Would you really consider buying parts for it and spending this much time in trying to repair it, instead of buying a way better phone for less than 100 bucks?

As a hobby, yes - I think this is why the bulk of us is keeping it; but anything other than this - I'd suggest to let go ?

Just tried out this awesome ROM, man the experience is great. No major lag, no bug and battery life send to be nice. This can be considered one of the most all-around best ROM. Also the installation is now simple and easy. Big thanks to the OP for delivering such a masterpiece.

New build 20160915

New build is up.

Bluetooth and remote submix audio are fixed. Since this is a kernel fix, it would have probably been the cause for random apps crash as well. The random apps crash seemed to be gone after the fix for audio issue.

This ROM should be as stable as the last MM ROM. The only regression now is the Screen Cast. If you need Screen Cast, then you should still stick with MM ROM.

Impressive Antutu score from AOSP Nougat

AOSP Nougat posted a very impressive Antutu v5 score on LGP800. The UX runtime as shown improved substantially compared to my best score with MM ROM. This is 100% stock, no overclock.

Hello, I have since yesterday testing the new version. Whether it has improved a lot ... but still gets slow and jammed. Also, I think or it seems to me that heats up a bit more than normal.

Also continues to present several restarts of the Apps, but much less.

Certainly it takes a very good way.

At the moment I return to the MM that works very well, I'll try the latest update.

regards

Hola, llevo desde ayer probando la nueva version. En si ha mejorado mucho...pero, todavía se pone lenta y se atasca. Además, creo o me lo parece que se calienta un poco más de los normal.

Tambien sigue presentando varios reinicios de las Apps, pero mucho menos.

Desde luego lleva un camino muy bueno.

De momento regreso a la MM que funciona muy bien, voy a probar la última actualización.

New build 20170520

Hi, new build is available. Instead of waiting for Google's June update, I decided to share this build because there were good improvements in kernel to make LG-P880 more appealing despite close to 5 years old device.

With the updated zram & zsmalloc, I enabled CONFIG_PGTABLE_MAPPING for zsmalloc allocator which is used by zram. This reduces CPU hogging due to swapping to zRAM because previously the CPU had to deal with compression/decompression operation and memcpy operation. Some kernel memory is also wasted through intermediary buffers used by memcpy. With CONFIG_PGTABLE_MAPPING, zsmalloc will use page table operation in MMU instead of memcpy. This is 6x faster (a no-brainer!!) for ARM CPU according to the author of zsmalloc.

Yes, I did feel the difference after enabling this kernel option for zsmalloc. Task switching now seems faster as long as there is no background sync jobs.

About zCACHE

Although cleancache is also updated, it will remain no-op for now because zCACHE is not enabled. Yes, I did get a chance to check out zCACHE, and I think at its current state, it is a conflict for Android because it is taking away memory that Android framework can use to cache dalvik processes.
[LG Optimus 4X HD] b886b:
Man, [MENTION=5799877]csk1jw[/MENTION] you continue to impress us. I am using your last build of this ROM and it already is very smooth and appealing. Couldn't imagine the now even more refined performance improvement. Will try to install the latest ROM tomorrow.

Full Open GApps-package

I used the FULL gapps. With the other, smaller packages, I had problems during the installation and first booting (services broke/stopped, ...). Now mostly everything I need works sufficient for me. You can later disable unnecessary apps (and services) to improve the memory of the phone. But you can also try to flash a smaller gapps package, depending on your needs. Just try it. Perhaps they all work for you. :confused:

Hi [MENTION=5799877]csk1jw[/MENTION],

as Google updated their sources to AOSP, will you build a June security update for us?

You improved the kernel in your last build. Is there the security fix included which I asked last time, or not?

Thanks in advance for feedback and your hard work for our phone.

Cheers,

[LG Optimus 4X HD] csk1jw:
I am already testing 7.1.2_r17 (NJH47B). Last time, you mentioned about CVE-2017-2636. I did actually tracked down the upstream fix for this, but later discovered that this is not applicable for kernel used in Android. That feature is not configured to be compiled and included. That's perhaps why AOSP security bulletins never mentioned about it, so I abandoned the fix. I am not able to upload anything at the moment due to a service disruption to my internet provider.

[LG Optimus 4X HD] Phil_Smith:
Having no play store because you don't wanna install gapps?

You could try this alternative, if so:

https://xdaforums.com/apps/magisk/module-nanomod-5-0-20170405-microg-t3584928

This also offers an alternative to the play store (called yalp store).

Otherwise you will have to find the apps you wanna install as .apk files and download them from your browser, or flash some others (like gmail eg) in recovery, if they are available in .zip format

That would not be possible as Google has made the playstore dependent on the Google play service. However if u want to have a working playstore with only minimum resource consumption, u can try installing pica gapps but do remember to flash web view.zip.

Currently I do not have access to my p880. I would do this:

Copy the file p880-ota-eng.njh47bz.zip to old_boot.zip and to old_meta.zip.

Insert the boot.img file from the previous version into the old_boot.zip file.

To old_meta.zip, insert the META-INF directory from the previous ROM.

At first my congratulations for this awesome ROM which takes the good old P880 to the present age with the newest Android version.

I installed this rom following the instructions of [MENTION=5799877]csk1jw[/MENTION] but with pico-open-gapps and web-view fom deltadroid. After 2 days it began to lag. No resource-eating apps were installed. I observed this behaviour in the last 2 versions of csk1jw's AOSP 7.1.2.. The speed before this is really impressing for this device.

In the penultimate version the lagging comes with the imposibility to slide down the 2nd slide of the notification-bar.

Have somebody a solution for this? Thanks
