LG G4 Verizon Wireless VS986
Stock everything, unrooted, and up-to-date as of post
Android Version: 6.0
Security Patch Level: 2016-03-01
Kernel: 3.10.84-g4790274
Build: MRA58K
Software version: VS98625A
Device encryption enabled, but not on the SD card.
All apps are installed on the device. The SD card only contains music, podcasts, and pictures.
Issue: Starting this week some times when I reboot there are missing apps when the phone powers back up. I havent noticed this after every reboot, but maybe i...just havent noticed.
A few days ago I rebooted my phone to see it "Optimizing apps" after entering my encryption password as if I had cleared dalvik cache or performed an OS or kernel upgrade or something. After completion the phone started up as normal but probably a dozen apps were missing. Most notably Hangouts, my calendar app, and Google Now... I rebooted again 2 nights ago and Pocket Casts, my budgeting app, and Light Flow, amongst others, were missing. I rebooted again this morning and my fking launcher was missing (Nova). WHAT THE HELL IS GOING ON WITH MY PHONE?
Even stranger is when I reinstall an app I barely need to change any settings; the data must still be on the phone because almost all my settings and profiles are immediately present. When i re-installed my budgeting up I was still signed in and synced (cloud subscription service). When i reinstalled Nova my desktops were exactly how they were minutes earlier before the reboot. After re-installing Hangouts I was still signed into the appropriate google accounts and not signed into the one I don't use for Hangouts. When I re-installed Google Now I wasn't even presented with the setup wizard and tutorial and all the cards I'd expect were there and accurate.
Since the VZW G4 is not easily rooted or bootloader unlocked not only have I been stuck with whatever Verizon and LG deemed worthy of me using (read: NOT using) in addition to already being on my second phone due to the boot loop hardware issue., but now i've got this to deal with? This phone was supposed to be awesome, but if not for the removable battery and sd slot I'd have moved on months ago.
I'm gonna FDR this evening or tomorrow evening if I can't find a real solution. Has anyone seen anything like this before???

bump

Personally I hadn't heard that before, but a quick (Google) search indicates it's happening with various phones. My first thought was check for virus..

Performed a FDR this week and the issue has been resolved. Super weird.

[Q] purchased apps disappeared?!

So i'm runnbing the march 28th cm11 nightly, and a few days ago, I noticed two of my most used applications (also, the only applications I've bought on google play) strangely disappeared from my home screen; I went to the app drawer to put them back, and they were not there either. So I open google play to reinstall them--only it says they ARE installed. Trying to open them from google play results in an instant FC. So from google play, I uninstalled and reinstalled--same results. Going into settings --> Apps, both applications show up, but in place of their regular icons are generic android icons suggesting the apps are on my SD card...

I had the exact same problem and had to go back to the 0326 build. I asked the very same question on the CM thread and somebody suggested that a clean flash should take care of the problem (though, to be honest, I've yet to try).
Sent from my SGH-T999 using xda app-developers app
--EDIT--
Just tried flashing the 0331 update clean and downloaded one of my paid apps. I'm still having the same problem. Going back to 0326.

Sensors issue (acc., pros., gyro., lux). Android 5.0.1

My devices setting: stock OS, stock kernel, latest twrp and chainfire rooted. Nothing else. I updated from Android 4.4.4 straight to 5.0.1 (5.0 skipped) with fastboot clean flash, data, cache wipe.
So, the story went like this. I read a book on Google Play Books in landscape, then I put my device into sleep mode by closing the magnet cover. I closed it in landscape mode and left it in landscape.
Later, when I wanted to use my device again and I opened the cover to wake my device, the display was stuck in landscape. I didn't lock the autorotation.
I downloaded the app "Sensor Kinetics-Innoventions" to make tests of my device's sensors, pretty every kind of sensors. Here are the results, I attach some screenshots showing that the sensors cannot be detected at all (no numbers indication changing around. If you don't understand what I mean, try out the app yourself).

See, even the lux sensor doesn't work. Now my screen brightness doesn't adjust to the surroundings even when "adaptive brightness" is switched on my device.
FYI, I did a clean update from KitKat 4.4.4 to 5.0.1 skipping 5.0 using fastboot and official from factory image extracted system.img, boot.img, etc., wiped data and this kind of bug is what I encounter.
Normally, when the sensors are working, the app would show something like this (after reboot it fixed the issue, but only for a short time and I quickly made a screenshot):
The thing is, now, even a reboot won't fix the sensors issue. I am not in a mood to do all this flashing and setting up again, don't have that f*cking time. [emoji36]
Finally, I found a solution and temporary fix. The bug is actually caused by Google Now (I don't know which version though, maybe the lastest). I went to the Google Now "Ok Google voice recognition on every screen" and disabled it, rebootet and voila all sensors are working again. It has something to do with Google Nows constant voice recognition-ish thing. So this fix worked for me. Anyone wanted to know, here it is. Cheers and peace.
Nice to know
impressive!!! worked for me as well !

ZenFone 2 - Flash memory failing?

Hi everyone,
This is regarding my ASUS ZenFone 2 ZE551ML (1.8 GHz CPU, 4 GB RAM, 16 GB ROM). A few days ago, after 1 year and 11 months of excellent service, suddenly I saw that some of the apps (Play Music, ASUS MiniMovie) were corrupted. But a simple uninstall and reinstall fixed them. Later that day, I was about to open settings when a message popped up "Unfortunately, settings has stopped". Rebooting the phone did not fix it and I was totally stuck as I was unable to clear the data also for the settings app which also requires "Settings" to function. I managed to do a factory reset after which, I could not even get to the home screen because that involves the Settings app as well.

}
I went on to proceed with factory reset from the recovery mode and to my shock, the recovery mode was also corrupted. Screen just froze with a USB logo. I tried to flash the recovery with xFSTK but got write error.
Then I took apart the device and cooled the flash memory (SK hynix manufactured) with some IPA.
The device booted up and was able to get to the home screen. Then I followed the ASUS standard downgrade procedure to downgrade the device from Marshmallow to Lollipop (which should force flashing of the recovery as well and everything). Phone was stable then. Then following ASUS standard upgrade procedure, I upgraded to Marshmallow and did a factory reset again. Set up everything and phone is rock stable now, performs good as new with no slow downs or anything.
My question is "What exactly happened?" It was never rooted and very well taken care of (even looks like new). Is the flash memory failing? Can the firmware get corrupted on its own?
Any answers would be appreciated. Thanks.
Hello I am also having the same issue? Can you please explain more about the way you have recovered. I love my Asus Zenfone2. I am trying to do Factory RESET which causes this issue. Do you mean, use IPA to clean the Memory side? Please help me. My email ID is [email protected]
Firstly, try to flash it with xFSTK using the tutorial here on XDA. If it fails, then you need to take the phone apart.

Unable to Login to Dropbox After Installing LineageOS

As per the title: a couple of weeks ago, I installed LineageOS 14,1 on my HTC One M8 [previously had rooted Marshmallow GPE installed]
Since then, I've been completely unable to login to Dropbox. I just get this really uninformative dialogue each time:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and an equally uninformative message in CatLog:
Code:
03-02 15:31:58.151 E/com.dropbox.android.user.AccountStore(28183): Failed to add account
Annoyingly, even though the error persists, whenever I try to login, I receive an email from Dropbox saying "We noticed a new sign in..." and, when I visit Dropbox in a browser, my phone is listed as being a linked device. I can also access Dropbox without a problem via browser on my phone. It's only the app that keeps throwing up this error.
I've tried all the usual tricks like uninstalling & reinstalling the Dropbox app as well as clearing Cache & Data. Also asked Titanium Backup Pro to remove all traces of Dropbox. But nothing has worked. I still get the same error and Dropbox support have been about as much use as a chocolate teapot –unable to do more than suggest I try re-installing the app.
Now, I'm 99% certain that the problem is with Dropbox but, seeing as it only began after I installed LineageOS, I've got to ask whether anyone else has run into similar problems and, if so, how did you resolve it?
Can't help you, it works perfectly for me...
It's unbelievable. I have nuked every single scrap of data relating to Dropbox from my phone; uninstalled app, deleted cache, deleted data, asked Titanium backup to remove all traces of it. Done a root access search for any files/folders on the whole of my device with 'dropbox' in the name and deleted them too. And yet, when I re-install it again and try to login, the exact same thing happens. I've never known an app to so stubbornly refuse to let its slate be wiped clean.
And, as I said in my 1st post, I'm pretty certain the culprit is Dropbox itself. But I just wanted to check in case there was some weird LineageOS voodoo involved too.

[QST] - N976B - S-Pen stopped working after rolling back to stock

Hi there,
I have an issue with my S-Pen. it suddenly have stopped working with my device.
I own a N976B Note.
I guess it is an issue with the firmware, because the stylus is recognized on my other devices and the other styluses are not recognized on my note.
To help you understand the history i want to sum up some steps.
1. my phone had a t-obile branding, witch i wanted to remove, so i flashed another csc rom to get rid of that. (back in 2020)
2. After some annoyance by advertisement and the wish to get root and a custom rom, i installed Dr.Ketan Rom and was pretty satisfied, but the hassle with manual updates was a draw back, so i decided to roll back to complete stock to get OTA.
3. After some huslte and some rookie mistakes by trying to install a n975 stock rom on my device, i figured it out and flashed the matching rom. but now the stylus or the digitizer seems to be corrupted. the firmware version is not recognized by the phone. see the screenshot below:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After some attempts to get it running again, i installed the very stock rom for my phone several times. (N976BXXS7FUI1)
I even checked "re-partition" and flashed with the matching pitfile in odin.
But there still no luck.
do you guys have some tips?
big thanks in advance!
greeting
Play with it. Spen's can be ornery as mules, once you get it going you're good.
They don't like being neglected for months.
My stock one was neglected. Took a couple days of playing with and then boom it stated charging like nothing ever happened.
Until it shows it's taking a charge it will do nothing. It will play dead.
Try clearing the system cache, reset network, pray to the pagan gods, play with it more... in and out, etc. Try enabling multiple spens, try disabling same... don't cross your spens, use the one for the 10+
Guess it just needs a good fk to get it going
I have 2 10+'s, both stock* and both run very well. Loading custom roms isn't needed, can kill desirable features and makes troubleshooting** much more difficult. That said if you're back on a stock rom the spen and associated hardware/firmware/software are likely good... it's just showing you who's boss. Play with it at least once a day, it will likely perk up in a week and stop it's wallflower act.
*with a package disabler and heavily optimized. I never update if it's running fast and stable; many apps are still running on their factory load as well. One 10+ is running on Pie, one on Q.
**Do Not enable power management. Make sure you didn't disable a needed parent/dependency apk! Do not ever, ever load Android 11 or higher, the kiss of death. Of course I could be mistaken, but probably not...
