Help Me Debug my Mom's Tablet - LG G Pad 7 Questions & Answers

I set up a v410 for my mom. It runs LineageOS 14.1 with the pico Open GApps. From time to time it freezes and the backlight remains on. This can happen either during normal use or when switched off. In either case we need to do a hard reset. I tried to inspect the logcat output (in attachment) but I don't understand what's wrong. Any clue? Many thanks!

I've had the V400 and I sold it with stock Lollipop Firmware, if I was you I'll go back to stock and then set it up for your mom and she would have less problems with the tablet.

[ASUS A500CG] Screen locks and unlocks randomly after 6.0.1 update

After updating my zenfone 5 (intel 2.0GHz) to android Marshmallow screen locks and unlocks randomly when it's laying in landscape or horisontal position(if I handle it with any angle it also does, but less frequently)
I have no idea what to do. I have tried unofficial CM13.1 and Resurection Remix and it's the same(I made clean flash of course). Dirty unicorns doesn't boot at all, so I have no chance to check it.
Maybe I should flash any speciffic firmware to use marshmallow without problems but I have no idea wchich one... (Is there any step-by-step manual of moving to MM and flashing these ROMs? I'm not sure but i think I have used this one)
The second problem but a bit smaller is that I can't connect to the cellular data internet but i'd focus one the first one.
Here's the video:
https://www.youtube.com/watch?v=qEAg6K3z0OE
If I enable any screen lock I just can't use the phone
Before Marshmallow update(on stock ROM, but unlocked) there was everything ok.
It also doesn't locks on TWRP, only on system
thats came from bootloaderunlock you can use cm 13.1 kernel and enable dnxfix for this second dirtyunicorn is booting when you came from cm based roms you must make a fullwipe then dirty is aosp thanks
Thanks
Ok, I flashed CM13.1 boot img. It's the same. I also tried to reflash whole CM from here: http://forum.xda-developers.com/zenfone-5/development/cyanogenmod-13-t3382702 and it doesn't work.
The phone still locks and unlocks its screen :/
I made full wipe of course...
"dnxfix" - do you mean "dnfix" wchich is mentioned in cyanogen's thread? Ok, I'll try it. And slockfix. It looks promising
Have the same problem here. The problem goes away on airplane mode though.

Most stable Lollipop/Marshmallow ROM?

Hi! I think I've tried every Lollipop/Marshmallow ROM out there, but I haven't found one as stable as KitKat ROMs (CM11/Stock). I just want a Lollipop/Marshmallow ROM that doesn't hang every time I open YouTube from recents (many apps suffer of that too), and with working WiFi (had this problem with CM13), and with decent battery life. CM13 is actually one of the most stable ROMs I've tried, but it had serious WiFi problems (it simply disconnects from the WiFi and then reconnects saying it doesn't have internet access, very annoying), some kind of TV-like static when booting and sometimes when unlocking the phone, and the recents cards sometimes got cut off (though this is not really a deal breaker). The only Marshmallow ROMs I haven't tried are BeanStalk and Mokee because they are based on CM, so I supposed they have the same problems. So, what's the most stable Lollipop/Marshmallow ROM you have tried? And can that ROM be used as daily driver?
Thanks!
Sorry for my English lol.
Which other Roms have you tried?

Exodus (5.0, will try 5.1), BlissPop, DirtyUnicorns, dhacker's unofficial CM12, Mokee (5.1), ResurrectionRemix, unofficial CM13...
EDIT: Tried Exodus 5.1, really slow.
MoKee
So far, so good (It's only been 24 hours since I've installed it) on the 17-01-29 build of Mokee here
Wifi has been solid with no issues, rom seems stable, and YouTube ran fine from recents.
Update: Had strange problem with downloading email attachments with both gmail and Yahoo mail. Back to stock KK for the time being.
Update: Turns out the above email problems had to do with permissions.

It doesn't even boot here, first time it booted but it said that encrypting my device failed (WTF?) and then rebooted to do a factory reset, and it wiped the system partition. xD
I installed it again without Gapps and now it won't do anything, it justs sits there in the bootanimation for several minutes and then reboots. Perhaps​ I didn't downgrade correctly? How did you downgrade? I used RSD Flasher, and it has worked fine for me in the past.

It took me awhile to find the procedure and files that I used to downgrade/upgrade, but I finally did. Thanks to Nobe1976, this method of going back and forth from KK to JB doesn't require a PC; There are 2 zip files that you can flash w/ TWRP to go back and forth. Here's the procedure and file links: http://www.droidrzr.com/topic/50096-how-tomobile-downgrader-flash-back-10-09-14-14/
I too thought Exodus was stable, but slow. I liked using MoKee 5.1, but I had an annoying problem with it that I couldn't solve: Every time I picked up my phone, there was a notification to sign back onto my WiFi network. It did so without asking for any credentials, but it got too annoying for me.
Right now, I'm using PacMan Rom (4.4.4), and it's been performing very well and is stable. Here's the link in case you wanna try: https://s.basketbuild.com/devs/pacman/moto_msm8960/KK/release

Thank you so much! That will save me so much headaches lol.
I'm using lastest CM11 snapshot, working fine, but I find the battery doesn't last as much as in CM12.1.
EDIT: I'm writing from Mokee 6.0! That method for downgrading works flawlessly!
Mokee feels better than CM12.1 except by that TV-like interference when you unlock the device, and I haven't tried the WiFi, but it looks okay.
Thing to remember while reading all of the below, I have an XT905, with a JBBL.
I'm currently using "cm-13.0-20161205-ilichva-xt907_jbb.zip" for my daily. The only repeated "fails" I have is where WiFi will disconnect, however, it only happens if I am not using it and the phone is asleep. One thing I have noticed is that this is the only ROM that actually does go into deep sleep for me. I'm only on Wifi at home for extended periods (ie when phone goes to sleep). This may be the reason the other ROMs don't loose WiFi, because they don't go into deep sleep for me. My Wifi disconnects, and never is connected without internet. I just go into Wifi, select my network and say connect, and its all good again.
Previously (a few years back) I was using BlissPop (Lollipop), but did not use the latest build. I had better luck with "BlissPop-v3.9-moto_msm8960_jbbl-OFFICIAL-20150829-1751.zip"
Others I have used (Lollipop) and found pretty stable (ie used as daily for some time) were:
CARBON-5.1.1-Final-moto_msm8960_jbbl.zip
Resurrection-Remix-LP-v5.5.8-moto_msm8960_jbbl.zip
and for KitKat
LS-KK-MileStone-3.2-moto_msm8960_jbbl.zip
With the CM13 ROM I have a 64GB SDCard, F2FS cache partition, Xposed, Viper, a Linux Swap Partition (512mb) and personally find it to be the most stable ROM I have used (apart from WiFi) on the phone. Some of the Lollipop (bliss pop included) could not run my live wallpaper (Celestial Bodies). I have also noticed that at least one app using the CPU (a Solitaire game attempting to find a winnable deal manually) actually runs a lot faster in CM13 than in the others.
If YouTube bothers you, maybe you should try the alternatives such as New Pipe or OGYouTube etc etc. Actually, I just tried YouTube from the recents,and it worked fine for me.
As for the TV Static on boot (just before animation) I have had that since I first unlocked the bootloader; I thought It was normal. It has been independent of any ROMs and it happens for me on every ROM.
Mokee 5.1
Sorry for going off-topic but would any of you guys happen to have a copy of the last LP Mokee build that was released on 4PDA ?
MK51.1-xt907_jbbl-20160420-ilichva.zip
The link is unfortunately dead and I can't find a mirror anywhere. I'd like to save a copy just in case anyone asks in the future. If any of you have, would you please share privately with me? Thanks a lot!

The TV-like static seems to be something with the JBBL, it happens even in recovery for me (when the recovery locks and turns off the screen). About the WiFi, it disconnected even if I was playing a game or using the internet, but I live in a place where I don't have WiFi anymore, so it's not a problem.
Indeed, Mokee 6.0 and CM13 are the most stable ROMs I've tried, even more than CM11, except for the bugs said above, even the battery lasts more.
BTW, how do you increment swap? I've tried several methods, but it still shows 256MB.

I personally have only seen it happen when the I wake the device up. Never has it occurred while I am using it.:angel: Last night I was searching for another thing in Xposed, and I saw a lot of Wifi type modules. Though most were about turning wifi off when the screen goes off; but I wasn't looking for Wifi stuff, so maybe you could find something that helps.

I tried Mokee, and I cant remember why, but it wasn't OK as a daily for me. To be honest, I would find it hard to go back to a ROM (ie less than MM) that does not have privacy guard. I also forgot to mention on my phone I have Adaway and Lucky Patcher and > 10 boot scripts (such as swap, IO optimisations, trim command, disabling media scanner on boot ... etc etc etc)

I am guessing by "increment" you really mean implement? Assuming that, I use a boot script. Currently I use a swap partition, so, for that I:
1. create a linux swap partition on the SDCard using Minitool Partition Wizard
2. Put the card into my phone, boot it and Find out the partition details (eg "/dev/block/mmcblk1p2" on my card now)
3. create a boot script to enable it on boot. The meat of the script is:
Code:
swapon /dev/block/mmcblk1p2;
Previously I have used a swap file, which is actually more complex. Something like:
Code:
location=/mnt/media_rw/sdcard1/data/local/tmp;
file_name=swapfile.dat;
desiredsizemb=512;
dd if=/dev/zero of=$location/$file_name bs=1048576 count=$desiredsizemb;
swapon -p 16000 $location/$file_name;
Hope the above helps, and let me know if you get it working.

Mokee has be running pretty solid here, I'll try CM13 and/or BeanStalk in a few days, though.
About swap, if I run "free" in the Terminal it shows it has swap memory, and I tried several methods (well, apps) to increment it but no luck. I'll try yours in a few days.
About the WiFi and the TV-like static, I bet is some difference between xt905 and xt907.

Well, the swap you currently see is ZRam, which is a compressed partition of memory used as a swap partition. ie not a file or physical partition on an sdcard (as I use above, in addition to ZRam). To increase ZRam, you loose available memory. That can be simply changed with the following lines:
Code:
echo 1 > /sys/block/zram0/reset;
OR
swapoff /dev/block/zram0;
echo "201326592" > /sys/block/zram0/disksize;
mkswap /dev/block/zram0;
swapon /dev/block/zram0;
The number is 1024*1024*target_size (MB eg 600). I think you have to do it at boot time or you end up with device or resource busy messages.
Or you could use Kernel Adiutor - Virtual Memory
That actually reminds me, one bug I have noticed on all the CM13 ROMs I tried, was that the init.d did not work, I had to use Kernel Adiutor to implement it; and I have a lot of scripts.
Currently running the new Lineage ROM http://forum.xda-developers.com/showthread.php?t=3577746. Thanks to Ilichva...
So far, so good !!! Performing very well with no issues found yet. :thumbup:
It still has the WiFi disconnecting when asleep for me.

Performing well here, too! It has the same bugs CM13 had, but I feel is a bit snappier.
Is it just me, or is the default swappiness set at 100? (cat /proc/sys/vm/swappiness)
I actually tried lowering it to the android default of 60, and the ROM felt less "snappy", so put it back at 100

Possible Wifi fix?

I just want a Lollipop/Marshmallow ROM ... and with working WiFi (had this problem with CM13), and with decent battery life. CM13 is actually one of the most stable ROMs I've tried, but it had serious WiFi problems (it simply disconnects from the WiFi and then reconnects saying it doesn't have internet access, very annoying).

I have made a change to build.prop, which APPEARS to have bettered my Wifi stability.
Now, its only been a few hours, so its pretty early to say :fingers-crossed: it has definitely fixed it, but normally within this time, I would of expected to loose my Wifi connection, but it hasn't. :highfive:
Also, the change I made, I have read is actually only set at build time and thereby built into the ROM and not read from the build.prop.
The build.prop setting is: wifi.supplicant_scan_interval. My RAZR had it set to 30, while my N5 was set to 15. I have set it down to 5 (for testing purposes ) Searching the net will bring up heaps of explanation of what the setting is for (and also info saying its only a build time property)
So in summary, I have set the following build.prop
Code:
wifi.supplicant_scan_interval=5
And my WiFi has been solid for the past 3 hrs (normally in sleep except for being woken every 10 minutes to check its still ok ). Let me know if it works for you.

SM-910F with custom ROM shuts off on boot

Hi there, first off please forgive me if I get any terminology wrong - I've been learning way more about this than I ever intended...
I have a Galaxy Note 4 (SM910F / trltexx) that's causing me problems with custom ROMs - the phone gets to various points of the startup process, then either shuts off or reboots.
I'm posting this in the Note 4 forum as it happens with all the following ROMs:
- LineageOS 14.1
- Resurrection Remix 5.7.4 / 5.8.0 / 5.8.3
I assume that either there's something screwed up about the phone itself, or I'm missing something fundamental about what ROMs I'm installing.
When I first install the OS (adb sideload), it will boot up the first time around just fine.
On occasion (with all of the above) the phone has gotten all the way to the initial configuration screen (e.g. select a wireless network). I've tried all types of wipe and format/reset, both clean and dirty flash, no difference. The point to which it gets in the boot process seems random. When the phone is connected to a charger, it will try to reboot. If it is not connected, it just shuts off.
Stock Samsung firmwares (5.0.1 and 6.1.1) with stock recovery all worked fine.
Recovery is TWRP v2.8.7.0 (that's the only one I could get running, 3.x would not start up)
I've recently had the screen replaced, the shop did a poor job (my proximity sensor started acting up, I first tried replacing it, then tried the electrical tape spacer trick, which worked.) I'm also using an aftermarket Anker battery, for what it's worth (they're great, btw).
Any ideas? As mentioned it seems to boot ok with stock firmware, but I don't want to run stock because that's no fun.
Thanks for any ideas!

Proximity sensor stays in "close" position

Nexus 6p, unlocked bootloader and running 8.1DP.
Whenever I make a call and put the phone to my ear the screen turns off and never comes back on. I tested the sensor with the device info app and I the sensor stays in the "close" position when engaged untill the app is restarted.
I did some research and I found that some users had this issue with the Nougat update but no relevant solutions were found and the 7.1.1 update fixed the problem.
I would like to avoid factory reset or locking the bootloader if possible.
Can anyone think of a possible solution?
I tried the Proximity sensor reset app from the play store and that does absolutely nothing.
EDIT: Stable 8.1 doesn't fix the issue, even after clean install and manual flash and wipe.
I'm on SuperXe 8.0 Oreo built and it works flawlessly. I remember having that issue on nougat ROMs use to drive me nuts. Every time I needed the keypad I had to fight to get the screen back on. ?
Not a factory reset. Manually wipe the phone and apply the latest 8.0 image.
So after manually flashing the 8.0 image everything worked. I thought id give 8.1 DP2 a shot and I wiped and flashed this manually. It worked during the restore but stopped working after all my apps were back, so I thought it may be an app that's causing the problem. Strated in safe mode, issue is still there. I guess Ill just have to wait for the stable 8.1 release. If anyone else is facing the issue please post here.

[SM-T580] Lineage OS bug (Probably only for me.)

I have been searching the internet for a fix for VERY long. I am trying to put lineage OS 14.1/15.1 (I have tried both.) on my SM-T580. Once I install it on to my device, at first, it looks fine. Working like it is supposed to but, when I try to turn it back on, (Not booting it up) either it turns back on but it is not displaying anything. Other times, it shows lines on the screen. I tried installing a kernel, but that didn't seem to fix it. The kernel was for nougat 7.1.2. If someone (anyone!) could help me, I would be really pleased.
