[G Pad 8.3 Original Android Development] juniorhxcx:
Thank you, what a great news. This bug MicroSd is pretty boring!

I learned that it's not hardware problem (my fear), but the EMMC controller. The bug sdcard removal is caused by a bug in the Erasmus Mundus driver that dates back to the sdcard when you think that the sdcard is hung up. That in the case of ROM Stock 5.0.2 LG, in the case of Custom do not know whether it will similarly.:Boa:
[G Pad 8.3 Original Android Development] cronot:
Really?? I've been using a variation of this workaround for awhile to avoid the SD dismounts, and it works, at the expense of slightly increased battery usage. Will your fix work without sacrificing battery? I'm dying for some technical details on this :)
[G Pad 8.3 Original Android Development] Deltadroid:
I can confirm the sdcard unmount fix works without increasing battery usage. The real fix uses a working emmc driver instead of a workaround shell script.
[G Pad 8.3 Original Android Development] fefifofum:
Sorry I cannot give you technical details, I simply replaced the mmc driver with the one from palman latest kernel release. I think it's a better solution that trying to fix myself what LG broke.

Flashed latest build 20150921, and WiFi disconnects are more frequent now.
[G Pad 8.3 Original Android Development] Barracuda77777:
strange, I also flashed but having no problems at all. been watching netflix with no issues :)
[G Pad 8.3 Original Android Development] jt1998:
clean flash or dirty flash? If dirty, I'd recommend a clean flash of ROM, flash gapps, wipe cache/dalvik, then reboot and see if issues persist.
[G Pad 8.3 Original Android Development] scaramonga:
Just used the in-built updater, so yeah, maybe a clean flash will help.
[G Pad 8.3 Original Android Development] Deltadroid:
You don't need to flash anything over. A factory reset is the same thing as a clean flash.
[G Pad 8.3 Original Android Development] jt1998:
I did the same but had no issues with my wifi afterwards. Good luck!
[G Pad 8.3 Original Android Development] scaramonga:
It's weird, as I have both 2.4GHz & 5GHz setup, but the 5GHz always reports 'out of range', and doesn't show if the 'preferred wifi band' is set on 'automatic' in settings. Changing this to '5GHz only' is the only way to get it to show up and connect, which it does does just fine, and with a strong signal, but it keeps disconnecting every 10 mins or so, for about 15 secs at a time?
[G Pad 8.3 Original Android Development] Deltadroid:
I have the same problem. Working on a fix.

I'm having the same Wi-Fi issues with official cm12.1. So, apparently the bug is coming from the official sources.
[G Pad 8.3 Original Android Development] Cal:
Having NONE of the problems reported. I always dirty flash - but I do always use Advanced>clean both catches before flashing.
[G Pad 8.3 Original Android Development] Deltadroid:
The bug is triggered by starting torrent downloads and putting the device to sleep.
[G Pad 8.3 Original Android Development] luisbraz:
Some people has issues on official cm 12.1 in the s4 mini. Perhaps the problem is in the cm code.

Sorry if I said something stupid, but I'm just a user and know nothing about building roms! :)
[G Pad 8.3 Original Android Development] Deltadroid:
That is good to know.

On a side note, I just noticed that the sdcard unmount bug also exists in official cm12.1. The unofficial rom here has the only working emmc driver for our v500.
[G Pad 8.3 Original Android Development] Cal:
I was responding to the WiFi disconnects...nothing showing about torrents, or I'm blind. Please state the issue in the last 10 or so posts please.
[G Pad 8.3 Original Android Development] Deltadroid:
Yes, the Wi-Fi disconnect happens when I start torrents and put the tablet to sleep.

Edit:

Actually, it still happens just doing nothing.

Edit 2: I want to specify that the Wi-Fi icon in the status bar still appears connected when this occurs. The problem seems more like a DNS issue. I've tried both dhcp and static IP with the same results.

Thanks for your work Deltadroid , thanks to your ROM i finally can move app to SD and i can see my 5 GHz band on my Archer C7 router unlike with the official 12.1-20150901 ROM

Thanks! I hope i do not have to do a clean install?
[G Pad 8.3 Original Android Development] Deltadroid:
Smooth as butter with the latest release. Thanks! All the little annoyances I used to have with official cm seems to be fixed with this rom. :)

Edit: the battery management is much nicer on this rom than on official cm also.
[G Pad 8.3 Original Android Development] fefifofum:
That depends. Did you read the install instructions on first post?

Thanks! Nice to hear about battery management. I spend so much time with usb connected for debugging that it's hard for me to tell about battery... :o

Yesterday i did a clean install of your ROM with Delta's gapps. Everything works perfectly. An unexpected bonus is ability to install apps from Amazon Appstore without unmounting SD card. I acted like a newbie and actually did not read the information about install. Sorry for that. How do i get home i install the new version. Thanks again!

does the quickremote app work for anyone, not sure if it is my tablet or my tv?^^

and is anyone else having problems with hwa on videos? this issue appears even on stock cm.

when i go forward and backward in a video for a few times, audio and video became async, plus the video starts to lag.
[G Pad 8.3 Original Android Development] Deltadroid:
The quickremote app is added for testing purposes because the infra red driver works with this kernel. The problem is that the system development kit for the quickremote app does not include open source for the framework necessary to use quickremote. If someone ever figures out how to add the necessary framework to our system, then the remote control app should work.

IR

Hi,

I can not get working the IR remote. I have tried a this app and many other.

https://play.google.com/store/apps/details?id=com.raon.aremotefreegalaxy
[G Pad 8.3 Original Android Development] Deltadroid:
It needs framework support added to the ROM before it can work. The framework is closed source, so we need to reverse engineer it first.
[G Pad 8.3 Original Android Development] mityokm:
Thank you
[G Pad 8.3 Original Android Development] fefifofum:
With what video app are you having the async issue? With what video formats do you have the issue?

Yes, IR remote is not working and it's a known bug, already described in post 2. I don't think there is any aosp based rom for the gpad in which IR remote is working yet.
[G Pad 8.3 Original Android Development] Darkmasterhk:
thanks for replying.

MX Player Pro + codec (ac3 + dts) -> mkv /mp4 -> h.264 + ac3/aac

here mostly the lag happens

vlc -> same video/audio

strong async

i think vlc is still in beta? anyway i only used to verify whether the lag is an MX or rom bug.
[G Pad 8.3 Original Android Development] julesism:
YES! I can connect to my 5Ghz WiFI with this ROM/kernel! It's been an issue for me ever since I started using 5.1.x based ROMs. The official and _infected CM12.1 builds (and several other 5.1.x ROMs) do not "see" certain 5Ghz channels, especially the higher channels. I saw this ROM and decided I'd give it a try..... tablet automatically connected to my 5Ghz WiFi :)
[G Pad 8.3 Original Android Development] fefifofum:
I'm unable to reproduce the bug you are having. I also use MX Player (no Pro) and tested with several mp4 and mkv files, no way to get async. Does anybody else have this issue? Could you send me by pm a video sample that gives you problems, or maybe a download link? Otherwise I will need a logcat and dmesg to see what's the error.
[G Pad 8.3 Original Android Development] Deltadroid:
When using MX player, is there a difference between HW and HW+ enabled playback?

Testing with HW enabled uses the stock video hardware acceleration. HW+ could have issues.
[G Pad 8.3 Original Android Development] Darkmasterhk:
Well uploading the movies wouldn't be legal, I guess. (Digitalised DVD collection)^^

Reproducing the MX lags takes some time (as mentioned async only in vlc).

I get them mostly after switching between some movies and scrolling forward and backward in time.

Here a video showing the "lags". since the last MX update it seems to be better.

edit: Drive link

First half with HW second SW, look at the stage when it rises.

Attached a log it should also include the vlc async issue.

HW+ seems better than HW, but as mentioned the lags only appear rawly and only after

many switches in the time line.
[G Pad 8.3 Original Android Development] Deltadroid:
I had problems with async using HW+ after seeking through video. Switching to HW did not have async after seeking through video.
[G Pad 8.3 Original Android Development] Darkmasterhk:
as mentioned no async with mx, the movie just starts to "lag", as if it skips some frames.

it feels like watching a movie on an old pc.^^

for me only sw fixes the issue.
[G Pad 8.3 Original Android Development] fefifofum:
Ok, so let's forget about vlc and HW+ in mxplayer, async it's their issue. About lags, I don't get any lag even when watching full hd videos, so digitalized dvds shouldn't lag either. I guess the problem has to do with the encoding and/or the media repos we use (which are included in cm sources). I will need a logcat to see what's the problem, but possibly there is nothing we can do about it...
[G Pad 8.3 Original Android Development] Darkmasterhk:
so, issue resolved... it was actually my fault, I accidentally mixed my older encodes(xvid) and my newer ones(x264), so the issue appeared because of some faulty encoded movies.

I'm really sorry to have caused you trouble because of my bad organized movies. :(

[G Pad 8.3 Original Android Development] Deltadroid:
I'm surprised to hear that. I have not had one since changing to the palman emmc driver. It was happening to me constantly with the LG emmc driver.

Make sure your card is formatted to FAT, not exFAT.
[G Pad 8.3 Original Android Development] luisbraz:
I have a sd card in the tablet and I think that it never unmounted! At least, I never had an unmount notification, and when needed, it's allways there!
[G Pad 8.3 Original Android Development] Deltadroid:
There is usually no notification. It is only visible in the logs.
[G Pad 8.3 Original Android Development] luisbraz:
Where can I find those logs?
[G Pad 8.3 Original Android Development] Deltadroid:
Would you happen to also be using Google Webview instead of the stock webview? I'm starting to wonder if Google Webview is causing these reported problems with the internet.

Perhaps we should also not be calling this a wifi disconnect problem, since the wifi still seems to be connected from the looks of the icon in the status bar. A better description of the problem is actually that the internet just stops working for a few minutes once in a while. During this internet outage, I am also unable to connect to the router from the tablet on the local network. The network just becomes not responsive and it has nothing to do with sleep mode or torrents.

This random problem with the internet seems to be a bug with an application that gets installed from the Play Store because I have no internet problems with a clean installation of this ROM with no other apps installed.

logcat
[G Pad 8.3 Original Android Development] cronot:
It's formatted as FAT32. It also has an additional ext4 partition that I use with Link2SD to hold the obb files from some games... Yeah, I realize this is frowned upon here, but I also can't see how this would cause the FAT partition to unmount.

Another telltale sign is if you have an app moved to SD (standard Android way), the SD has unmounted and you try to launch that app, it will either crash or android will say the app is not installed; the later used to happen on older builds, the former happens with more recent builds (past 3, I think). The only fix for this behavior is either rebooting or going into Storage settings and unmounting and remounting the SD.

The unmounting didn't happen again since my previous report, so I'll leave that be for now - if it's rare enough, then I guess I'll just endure it, the improved battery life is hard to let go... if it gets too frequent tough, I'll have to go with that damn workaround again... :P

Edit: Oh Shucks... it just happened again. I guess I'll have to live with that workaround anyway...
[G Pad 8.3 Original Android Development] scaramonga:
Interesting.

Fresh wiped device, (cleared the lot - Data, System, Cache, Dalvik & Internal) installed latest rom (21) from external source, minimal Gapps package, Exchange, GMail, Chrome & YouTube packages from OP posting. That's it, nothing else.

Still happening.
[G Pad 8.3 Original Android Development] cronot:
Another unrelated problem (not too big though, just a bit annoying): has it ever happened to you that the wallpaper is reset to the default lollipop wallpaper on its own, from whatever wallpaper you've set before? I'm not sure if that's specific to the G Pad though, I *think* I've seen it happen with my phone once as well, but I'm not sure... But it happened twice today with my G Pad. I'm getting a little worried...
[G Pad 8.3 Original Android Development] Deltadroid:
Thanks for the info. It sounds like Google Webview is not the problem then. I will keep testing to see if I can narrow it down.

---------- Post added at 03:17 AM ---------- Previous post was at 03:16 AM ----------

I have not had this problem before. It sounds like it is related to the launcher. Is your wallpaper on the internal or external sdcard? I would suggest having it on the internal sdcard.

---------- Post added at 03:21 AM ---------- Previous post was at 03:17 AM ----------

Link2SD could be causing it. It would be interesting to test without Link2SD to see if your problem goes away.
[G Pad 8.3 Original Android Development] cronot:
It's on the internal sdcard. That's where Wally saves the wallpaper anyways. Doesn't the theme engine, launcher or whatever copies the image file into /data before setting the wallpaper, though? Using the wallpaper directly from whatever media it is, doesn't sound like a good idea to me. I know for sure that I've deleted image files that I've been using for wallpaper and the wallpaper would still stick, even after reboot.

As I said, it's not a big deal, it's just weird.

Did that - got rid of the ext4 partition and reformatted the SD card only with a FAT32 partition. Still got the problem. Do you mean I should uninstall Link2SD completely?

Edit: Uninstalled Link2SD, still had the problem. One curious thing I've noticed - the wallpaper thing have been happening more frequently, and it seems it occurs at the same time there's an SD card unmount. Maybe it's just coincidence, I can't see how these problems could be related since the wallpaper is saved on internal sd anyway... I'm just really puzzled because all these strange behaviors started pretty much out of nowhere, everything was working really fine for a day or two after I've updated the build.

Edit:

Here is the official Google bug tracker for this issue.

https://code.google.com/p/android/issues/detail?id=170078
[G Pad 8.3 Original Android Development] fefifofum:
Anyone who wants to report bugs should read post 2. There are apps that help you get logs if you don't know how to do that.

What I don't understand is why I never had a single sdcard unmount (and I'm not the only one), while some users have sdcard unmounts frequently (and not only with this rom). I'll need logs if you want me to try to fix it.

That issue shouldn't be device specific, so probably an update from cm will fix it. You could also try to delete the data from your launcher to see if that solves your problem.

That bug was never present in my builds, and it was recently fixed in official builds.

I don't think that is related to the issues you are having. Those logs are related to gapps and network location. Maybe you could test if a clean install (without installing gapps) gives you the same issues, so we can find where the issue is.
[G Pad 8.3 Original Android Development] Deltadroid:
If you have ever factory reset your device while there were apps/games still moved to the sdcard, then your .android_secure file has stale containers in it which can be several gigs in size.

If you have any apps moved to sdcard, move them back to the internal storage and reboot to recovery and delete /external_sd/.android_secure. This will cause a fresh .android_secure to be created on the sdcard without stale containers in it.

I've noticed that my .android_secure was filled with stale containers for all the apps I had moved to the sdcard before I had factory reset the device. My logs still had messages about games and apps that I had previously moved to the sdcard before factory resetting on a clean installation.

For what it's worth, SD isn't mounting at all with latest build ... I had the dismount error with previous builds at random but at least it worked a bit after boot :) now log mentions «unmounted» when I try to mount it. Having quite a bit of data on it I can't reformat it at will but will do so if needed.
[G Pad 8.3 Original Android Development] Deltadroid:
Does the sdcard mount in recovery mode?

I would start by making sure no app installations are moved onto sdcard. Next, manually delete /external_sd/.android_secure on the sd card in recovery mode. See if that helps. Your android_secure could be causing the sd card problems.

Wifi Issues

I've found an option on the router that may fix the wifi dropouts.

With some WLAN access points there can be power save related problems when WMM (Wi-Fi Multimedia) and U-APSD (Unscheduled Automatic Power Save Delivery) are enabled in the access point. This may cause the data transfer to phone stop every time the phone goes to sleep mode. As a result, when using e.g. the web browser, the user might have to push the link several times until the link opens. Incoming VoIP calls or push e-mail may not work properly because the phone does not receive the data packets when in power save mode.As a workaround, try disabling WMM power save in the WLAN access point.

[G Pad 8.3 Original Android Development] Deltadroid:
I think our sdcard driver can not really handle app installations moved to the sdcard. Formatting .android_secure helped in my case. My android_secure was filled with several gigs of stale data. The latest version of TWRP is currently not properly formatting android_secure in a factory reset. Although, android_secure can be deleted in recovery mode and a new one will be created when booting back to the system.
