That happened for me aswell. When i flashed the rom for the first time, it also disconnected when i went to the wifi settings via notifiaction bar (holding the wifi icon). After a full wipe and reflash that bug was gone.

I remember after the reflash i also had the disconnection bug, when i unlocked the tablet (only occured when the tablet was in standby for a longer time). But at least it did not disconnect during the actual use of the tablet. It only disconnected when it was in standby. There is also a option in the settings where you can actually can set this as a "feature" but it was disabled for me (Wifi alway stay activated in standby). Not sure if thats the real name of the option, cus my language is set to german. Maybe the disconnection bug has something to do with this option? Maybe its set to "never" although the user sees it as "always". Try to switch it to never and then back to always again. Could work but no guarantee.

//edit it also could be a problem with the wifi channel of your router. Maybe changing the wifi to another channel does the trick

//edit edit. One last thought: it could be just a displaying bug aswell, because i still get notifications about social media, updates etc, when my tablet is in standby. I will verifiy this thought with pinging my tablet in standby. You can also try this to see if it really disconnects or just displaying it as disconnected
[G Pad 8.3 Original Android Development] testman86:
first thanks for your detailed answer.

The problem while accessing wifi settings over notification bar I never had. This does/did in my case never influenced wifi behaviour.

I also thought that this setting "Wifi alway stay activated in standby" could be buggy or displaying the wrong setting even if it shows "always". (btw I am also german so I got what you meant ^^) So I toggled from " always" to "never" and back to "always" to at least try if this caused the behaviour.

Hmm, and the wifi channels should only be a problem in 5Ghz networks cause I think some channels are blocked in some countries. I am on 2.4 Ghz and not many wifis are disturbing each other here so I will keep first the router settings as they are. But could also be the reason (but all other devices never complained).

Mine was really disconnected and not just displaying wifi connection lost, cause some apps were giving errors that no internet connection is available. And after wifi was displayed as connected apps work properly again.
[G Pad 8.3 Original Android Development] c0re.f4m0us:
Then your last chance is a full wipe.. i really cant say when the disconnects stopped for me.. as far as i can remember i did a backup of everything and then wiped dalvik cache, cache, system and even data -> flashed the latest rom version -> still had the bug -> changed wifi settings to 2.4 ghz only -> still had the bug -> reboot -> success! :good:

The latest official CM13 for my LG G2 has the IR blaster working. Is it possible this is a lead to getting IR blaster working on the LG G Pad 8.3 (v500?)

Forgive me if that's a ludicrous supposition. The only thing I know about CM ROMs is following the instructions on how to install them. I just know that the two devices were released around the same time, so I thought it would be worth mentioning.

Apparently it was added on or around the 20160122 nightly, according to this reddit post

https://www.reddit.com/r/lgg2/comments/427dut/latest_cm13_nightly_has_working_ir_blaster_drivers/

I'm not sure how to find changelogs that old to find out what the change was, but I can confirm it works on my D801 T-Mobile variant.
[G Pad 8.3 Original Android Development] c0re.f4m0us:
I have another bug to report: When i got out of standby a notification about my sd card being corrupted pops up for a really short time. It took me a few times to see what the message says. This would not bother me but after 2 or 3 days the tablet ejects the sd card and does not recognize it anymore as long as i dont reboot. Even physically ejecting the sd card and inserting it again does not help.

I use my sd card as external storage. Its a 64gb sdxc sandisk. I tried formatting it with sdformatter and with this rom by itself. Always the same result.
[G Pad 8.3 Original Android Development] csick:
I've been having this issue since you first released your cm-13 builds. Like I said, I switched to adrianom's ROM for my daily driver, but I keep trying build of your rom every now and then, always having the same issue.

I also tried going back to the 4.2.2 bootloader to see if that made a difference, but it didn't.

I have attached my last_kmsg. This time, the battery drained all the way after the screen went black. Not sure if that makes a difference or not.

edit:

Yes, I did a clean install of this Rom
[G Pad 8.3 Original Android Development] Deltadroid:
Your logs show the following problem:

mmc1: CMD23: Command CRC Error.

This indicates that there is a problem with your eMMC since it is not responding when a command is given to it. Replacing your sdcard might help solve the problem.
[G Pad 8.3 Original Android Development] csick:
I started getting microSD card issues once I went back to the 4.2.2 Bootloader, which was what I was on when I posted that log.

I flashed back to the 20F bootloader yesterday, and I had the black screen issue again last night. (See attached logs)

I don't see all those emmc CRC errors in yesterday's last_kmsg, so maybe it's unrelated?

I'm going to remove my microSD card altogether for a few days and see if that resolves the issue anyway, just to be sure though.
[G Pad 8.3 Original Android Development] z0mghii:
Does anyone have any problems with their power button being flaky? Sometimes it takes me 2 or 3 tries for the screen to either turn on or off. Double tapping seems to work consistently.
[G Pad 8.3 Original Android Development] c0re.f4m0us:
Here is my logcat. I get a lot of unmounts and mounts. Would be really nice if someone could look into it :)

[MENTION=4517918]fefifofum[/MENTION] Hello, could you take a look at the gpu governos? I can only use ondemand or performance, if I select anything else it won't stock and it'll go back to previous governor. Thank you. (I would like to use simple governor has I think is the best for performance/battery.)
[G Pad 8.3 Original Android Development] tmihai20:
[MENTION=7513504]c0re.f4m0us[/MENTION]: I am not a specialist, but I could see that you have a 64 or more GB SD card, formatted as exFat. There may be a faulty media file (an mp3, a photo) because the Android Media Provider tried a lot of times to access the card and at some point the system unmounted the card. Maybe you should reformat the card and try to figure out what file is giving issues to the Media Scanner/Provider. Try to have the card also checked for bad blocks, there were some mentions about not being able to write, but it could have been because Android unmounted the card.
[G Pad 8.3 Original Android Development] c0re.f4m0us:
First of all thanks for the fast reply! Yeah its a 64gb sd card from Sandisk. I reformatted the sd card a few times already. With the sd formatter and by cm itself. After further investigation i also found a thread on xda, that claims that SanDisk cards could cause this problem. Some claim its because of the exFat, but fat32 does not work. Sadly i have only sandisk cards around. When everything else fails, i guess i have to buy one from samsung.

//edit: okay fat32 does work, i thought cm formatted it back to exFat, but the error remains

UPDATE: Looks like there is no issue with my SanDisk 32gb sd card. Also i remember that i had no such bug in the AOSP rom with the 64gb sd card.
[G Pad 8.3 Original Android Development] csick:
OK, to update, since I removed my SD card completely, I haven't had the black screen issue at all (going on 3 days now), so it's likely there's some correlation there.

I have a bunch of SD cards lying around so I'm going to try some different brands and see if I can't find one that works well (I was using a g.skill, probably not the most reliable brand for SD cards)

Interesting, I was also using a 64GB card when I had the black screen issue. I have a SanDisk 64GB card I can try to see if I have the same issues as you.
[G Pad 8.3 Original Android Development] c0re.f4m0us:
[MENTION=4029905]csick[/MENTION] thanks for investigating. It would be nice to know if someone else can reproduce the issue. Further i can't confirm the blackscreen bug like you had.

After looking through the DMESG log i found some interesting points:

Like you i got a cmd command error

mmc1: CMD13: Command CRC error

and another one:

mmcblk1: response CRC error sending SET_BLOCK_COUNT command, card status 0x400900

DMESG log is also attached.

I checked the SD Card for bad blocks as well - with no luck (fortunatley). When i dug through the internet someone claimed that selinux enforcing mode is the problem so i set it to permissive. But no luck there. Havent tried it with ext4 only with exfat so far.

Maybe someone comes up with a solution which may fix the blackscreen and sd card issue if there is some correlation.

Fantastic rom. Tried to make V50030B work for me, but was suffering from android 5.0.2 memory leaks, which I couldn't fix, so i took a plunge into cyanogenmod. I don't know why i bothered with the stock in the first place, as this is better in every single aspect. 100% reliable so far, more fluid, better on battery and nicely customisable. Thanks for your work!

Youtube @60fps

I can't play videos in the Youtube-app @60fps since i can remember...

3-5 seconds stream and then video is freezing, audio works furthermore.

An error of the app or maybe depended on your Rom?

On my smartphone (without cm) it works...

It does freeze at 720p60 as well, but only in YT app. When I am watching the same video using Chrome, it works fine even at 1080p60.
[G Pad 8.3 Original Android Development] Deltadroid:
Recently, CM13 code changed in system/bt that changed the clock reference when playing back videos. While trying to unify the clock code, they actually changed the time reference from MONOTONIC to BOOTTIME. For me, this has caused black screens while playing back videos. I personally had to revert these changes to get a normal playback without black screens.
[G Pad 8.3 Original Android Development] Giaki:
With latest ROM landscape lock screen is not working anymore, it is always set to portrait. How to change it? Thanks

when i wake the tablet from standby the wifi is always dropped but reconnects in 1-2 seconds. anyone else has this?
[G Pad 8.3 Original Android Development] Cal:
This is the first "quirk" I've had with the past ROM updates, and I too have a very slight pause on wake & connecting to 5G. I switched to 'auto' WiFi and all seems fine.

Very fast now...just a bit quicker than the last upgrade.

Great work! Thank you Fefifofum, and for great assistance, don't forget Deltandroid's constant monortering or we might not be so 'perfect'.

[G Pad 8.3 Original Android Development] testman86:
Holy ****, the latest version is really fast! I just upgraded from the previous one by dirty flashing and just wiping cache/dalvik.

Browsing in Firefox got really really smooth now.

And I tried to reproduce the Youtube issue with 1080p@60fps but video was playing flawless. Just when I tried to skip through the video playback stopped after few seconds and just audio keeps playing.

And the wifi issue I also had. I even had the problem that connection drops while using and did not reconnect. I switched to 2.4 Ghz channel and just have this idle connection lost but not while screen on anymore.
[G Pad 8.3 Original Android Development] takis:
60 fps are unsupported how can you have so??
[G Pad 8.3 Original Android Development] testman86:
I used the latest Youtube app and tried with this video https://www.youtube.com/watch?v=79ImZE0K7xc . If just watching from beginning video and audio were playing without issues. But when I start skipping through the video, video stops after few seconds and just audio keeps playing.
[G Pad 8.3 Original Android Development] luisbraz:
Suddenly I've start to have sd card dismounts! It only mount again after a reboot.
[G Pad 8.3 Original Android Development] Deltadroid:
I just tested this video and skipped around back and forth and it plays perfectly. Although, I'm using some modified kernel sources with a patched clocksource for video playback.

I guess our device does support 1080@60 after all.

Hi there. Thanks for the fastest rom ever. Unfortunately, there are many bugs as far as i have noticed.

- Wifi is loosing signal from time to time. Quite frequently.

Above all your works is highly appreciate it! Great job!:good:

I've been having WiFi disconnects for some time. Occasionally I'll wake the device and see no WiFi connection. When this happens it gets stuck in a loop of connecting then obtaining ip but it never actually connects. I can only resolve this by toggling aeroplane mode. After I do that it connects immediately.

I've been meaning to provide some logs but never got round to it (sorry). Fingers crossed that you've fixed it but if not then I'll grab logs for you.
[G Pad 8.3 Original Android Development] Deltadroid:
I've recently noticed the same behavior with Wi-Fi reconnecting in a loop and never connecting until I switch Wi-Fi off then on again. Hopefully, these latest changes will solve that issue.

It seems like this started happening after updating the Wi-Fi regulatory database (db.txt). It also seems like this only happens when the Wi-Fi signal is very weak.

I will test fefifofum's latest changes tonight.

I'm not having any problems either. before 240616 rom wifi was reconnecting every time when waking the tablet, but it was taking half a second and wasn't causing any problems. Now it stays connected. Not suffering from apps freezing/closing either, apart from getting "Gallery has stopped working" every time i switch to a 2nd user profile for the first time. (Since I downloaded a wallpaper on that user profile and applied it) Not really a big deal though so can't be bothered to fix it.

What is force closing?
[G Pad 8.3 Original Android Development] glyrakos:
Force closing is when you are in an app it is terminated suddenly. Sometime there is a message saying that something went wrong and some not.

Next builds i have installed them through dirty flashing and up to 29/5 everything was ok. Since then i face this problem and i revert back to 29/5 by dirty flashing and everything is ok (up to now 4 times)

I discovered I had a backup saved from December 3rd, 2015. Loaded it an it seemed very smooth and all good with 5g and 2.4g. Layout was a bit different and kernel was older, but it seemed very solid.

Perhaps too much tinkering to try and satisfy everyone and everything that can occur? Must be thousands of reasons to try...and either all is good, or for one improvement, 5 fail. Hard to please everyone and *nothing* will ever be perfect - but Fefifofum is trying...thanks to him I don't look for other ROMS.

EDIT: NOW USING 2016-05-21 Same weak WiFi connect on 5ghz (if it connects at all), but 2.4ghz connects and works *strong*. Both *were* working good with same router, same ISP, same signal strength. I get NO disconnects - or dropped, unless I touch the tablet along the bottom center.:confused:

EDIT 2: Just now 5ghz is starting on it's on...but not consistent. Must be something with my ISP provider - but is that possible with only one of 2 bands messing up??
