System Keeps Crashing - Google Pixel 2 XL Questions & Answers

Starting early July, my Pixel 2 XL on stock Google ROM has been crashing constantly. Tried a whole sort of troubleshooting but cant seem to fix it. Looking to see if someone can see something that I dont.
Symptoms
When Pixel 2 XL, on (PQ3A.190705.001, Jul 2019), charging and left alone, the phone would become unresponsive for up to 5 minutes, then proceed to do a soft restart and show the Phone is initializing. No problems when running the phone off the charger.
Troubleshooting
Tried the basic troubleshooting steps from Google Support (Update to latest system update, remove free space, safe mode, factory reset)
Tried reflash June factory image from Google (PQ3A.190605.003, Jun 2019)
Tried different charger
Disabled digital wellness app
Disabled the Private DNS and uninstalled Blockada (heard issues with it)
Nothing seems to work. Google support suggested that I get it exchanged under warranty, however, I feel like it is a software issue more than hardware. This is because when I monitor it under logcat when it stops responding, I see there is a whole bunch uncaught FATAL EXCEPTION so it seems that something is causing it to error out.
I am not too familiar with Android logs so I cant pinpoint it out. If anyone have more expertise can help with taking a look at the log to see what the root cause is, that would let me know what I should do for next step (ie try Android Q Beta if it is a system issue, get a new phone if it is a HW issue, or change certain settings).
Here is the log file
Thanks

No response bugs

Some background info.
I bought my pixel XL from the Google store and I believe it came with the 63L build out of the box. I have since made it a point to completely wipe and fastboot flash the latest image Everytime an update is release, right now I am on the 26U build. The only thing I have done to my phone (and these bugs happen before and after) is bootloader unlock and root.
The bugs.
Every once in a while, my volume controls will quit working. I notice it happen more if I cast to my Chromecast and play a song or video (seperate) on my device. I'll hit the volume button and literally nothing will happen. To fix this I usually have to turn the display off, wait a few seconds, wake it back up, then the controls work fine again. I do not believe it is a hardware issue because i can fix it Everytime it happens.
The second bug, probably the most annoying, is that my nav bar will become completely unresponsive occasionally while in landscape orientation. Say I'm watching a video on YouTube in full screen, if I swipe to pull out my nav bar and hit the home/recent/back button, nothing will happen. I will see the animation however no vibration (feedback) or a action occurs.
This happens in games, YouTube, web browsers, doesn't matter as long as my phone is in landscape mode. Also note that when this happens, my device refuses to rotate back to portrait. This leaves my only solution (same as the volume bug) to turn off the display, wait a few seconds, and then I back on. Sometimes, however, this don't even work, and I'll have to jump straight to settings from my lockscreen to force the phone to portrait where the functionality of the nav bar returns.
I've contacted google, they run me through the typical steps "delete cache, have you tried a reset, update to the latest software", but nothing fixes it. They have told me repetitively it's not a common problem and it's not a problem that's worth rma'ing over.
I've been discovering my pixel has many small issues that no one else has. Such as the horrible transfer speed explain in my earlier thread, these bugs above, refusing to charge when the device is off, etc.
Has anyone had similar problems?
@noidea24,
I've had none of those issues. In fact, my Pixel XL has been flawless.
Not good. I guess I'm going to try and force a RMA.

Sorry to nit, but when I read the statement above I can't help but wonder if you actually did a factory reset. Reason I say that is you stated "have you tried a reset" and you didn't explicitly state that you did.
I kind of doubt the responsiveness stuff you're referring to is hardware related, it's probably software.
Whether or not a rogue app is affecting your device or a root app is impossible to determine without doing a factory reset and carefully adding one app/change at a time until the problem comes back. It's a PITA but that's what I'd do first to rule out hardware, and I'd simply run email and messaging apps unrooted for at least 24 hours to rule out hardware issues before I start loading up my favorite apps.

A factory reset is far from a pain in the ass, and yes, i have done it many times. the only things that makes it suck is when i have to transfer files back to my device because (as mentioned) i have terrible transfer speed from pc to device.
i have literally done everything i can to make this devices worth the price, and things are only getting worse. Since the post (later that night) i factory flashed once again, and re locked the bootloader. No root, No extra apps, hell, the only apps i had on my phone to begin with were facebook messenger, and that pixel car racer, i dont use anything else. ive had an even worse bug come in where my phone completely freezes when opening google camera and swiping to the video section. ill have to hold power until it force resets.
ive been with xda since my Motorola droid, Ive built roms for the community for my lg g2 and my nexus 6. hell, i even built kernels for my 5x (not public), so im a little past your average user complaining about some things that dont work due to user error. these are legitimate device flaws and malfunctions, and i was simply asking if anyone else has experienced them. and since it seems no one has, i have deemed my device faulty. now i have to come up with $600 for a service hold to get it replaced.
My experience with Googles first official flag ship has been pathetic, and im hoping that this replacement device i get (eventually) will persuade me not to go back to my 6p.
Well if that's the case then yeah I hope a replacement device will solve your issues. Sounds like it will.
Didn't mean to rile you up, just looking for clarity.
Good luck!

Recent Issues

I've been experiencing several issues with my Pixel XL recently, and I'm not sure how they might be related to one another or how to resolve them. Before I resort to possibly resetting the device entirely, I was wondering if anyone might have any bright ideas.
1. I was having issues reconnecting to the Project Fi network after the connection was lost without resetting the device. This appears to have been resolved after a call to the Project Fi team, but toggling airplane mode did nothing.
2. Play Store app updates seem to take forever now. They get to 100% downloaded and just sit there for minutes or longer before installing.
3. Notifications for apps are just broken a lot of the time. They arrive hours late if they arrive at all.
Rebooting and/or clearing the cache do not seem to help with the above issues.
Does this all point to anything? I've never bother rooting the device, so I'm not sure what could possibly have messed things up this badly.
Sounds like a factory reset is needed. Sucks but it'll fix all your issues.

Strange [and serious] lag issue, please help

I had my Pixel 2 XL since first release, running stock releases updated each month, stock kernel, and using Magisk. I also have a Pixel 2, configured exactly the same way as the 2 XL and the exact same apps. Apps are updated at the same time, same for patch releases. I carry both and use them interchangeably each day. They provide carrier/coverage diversity and allow for a longer day without charge.
A few days ago, with no known reason, my 2 XL started exhibiting a very strange lag behavior. In trying to resolve the issue, I have tried clearing Dalvik, flashing back to February, re-flashing March, and today flashing to April. I have also cleared certain app data and tried a custom kernel Nothing has helped. The problem does not exist on P2.
The lag I have observed so far:
1) I use the Google Calendar "agenda" widget. On boot, the widget is blank and shows "loading" and can take 10 or 15 minutes for the agenda items to populate (as opposed to immediately upon start up).
2) Playstore app updates: It downloads the app, but seemingly hangs and the update is VERY VERY slow.
3) On flashing the April patch, on first boot, the "Completing Android update" notification progress bar took about 45 minutes to complete (as opposed to a few seconds like it should).
4) I use Lightflow. On launching the app, I keep getting "app not responding" message. If I keep tapping "wait", it will eventually load. It is just loading VERY slowly.
I firmly believe that all of these issues are related to a single problem, like a system resource that causing these lags. At this time, I cannot update apps because it would take hours just to update one app.
I really don't want to do a factory reset if I can help it. Too many things to reconfigure, even with TiBu. Does anyone have any idea as to what might be the cause? I would really appreciate any input.
Thanks.

I don't have a good answer for you my friend other than trying to run it in Safe mode for a while to see if it helps. Other than that, only other thing you probably can do is a factory reset, which, I know, bites the big one!

Thanks for that suggestion! The only condition I was able to test was to update apps. It went fine in Safe Mode. I rebooted back into regular mode and app update would hang. Based on what I read, the culprit would be a 3rd-party app?
I looked through all the apps that were updated in the past few days and do not see an app that would have the sort of large impact. There is no abnormal CPU utilization. Keep in mind that my Pixel 2 has the exact same apps and are updated at the same time. It has no such issues. I'm still lost.
The only update that could have an impact is Google Play Services. I'm on beta 12.5.21. Again, no issues w/ Pixel 2. I assume others don't have issues, we would otherwise heard about it by now.
Edit: Does safe mode run the ROM version of the Google Play Services?

Yeah the only slowdown I've ever had was I think right before the February update. I never restart my phone or let it die so I had been 25+ something days of uptime. Restart was all I needed and it was the only 25+ days uptime that had any slowdown. I'm stock and only beta app I'm running is LastPass.

My phone lags BADLY when I use Snapchat and facebook.
Considering the affected apps (Google Calendar agenda widget, Lightflow, Playstore "install" process, etc.). What do all these have in common?

Did you ever figure this out?
I'm still on March and have started having this issue. It's related to charging the device. Whenever I charge (and even after pulling off the charger) Lightflow becomes extremely laggy. Also, installing apps from the Play store exhibits the behavior you described in OP. Interacting with notifications is very laggy as well (i.e. - tap a notification to open the corresponding app, and the notification disappears and nothing happens...then 2 minutes later the app opens). This goes on until a reboot. After that, everything is fine until I charge again. Which, fortunately for me, is only once every 3 days.
Was not having this issue until recently and have been on March for a few weeks.

I have not, unfortunately. The Playstore app install has, for the most part, resolved itself, but the hang does return from time to time. Lightflow is still a problem. I wrote the dev but there is no response. The other issue is the Google Calendar agenda widget. It takes 10-20 minutes to load on reboot. Mind you, the month widget works just fine.
Take a look at these threads:

https://forums.androidcentral.com/google-pixel-pixel-xl/855985-screen-widget-loading-8-1-boot.html
They describe similar issues. I've also found other, similar observations but with no resolve.
I am on April and have tried a custom kernel. No joy.
Edit: Since I cannot test the calendar widget nor Lightflow in Safe Mode, I don't know if it actually is a system-related issue.
Edit 2: I do see a strange connection with charging, especially with Playstore installations and lags.

The only widget I use is the Fit step counter. That has always taken a minute or so to even show up on the home screen after a boot (8.0/8.1) for me. I don't feel it's related to my issue as that has persisted through all software versions I've used so far.
I'm beginning to think the lightflow issue is just that....a lightflow issue and it is affecting notifications, globally. And, it is somehow tied to charging state. I've seen lightflow do some weird crap over the years. I remember a simple gmail update caused lightflow to send my then device (htc tbolt) into constant reboots.

Well sir, you are EXACTLY correct. Based on your ideas, I disabled Lightflow and rebooted my phone. All was back to normal. Once I re-enabled LF, the problems came back. Thank you very much for pointing out your observations. I would have not considered LF to be the source of the problem, but it is now so clear. Again, I can't thank you enough (I'll "thank" both of your posts)!
I will try clearing the LF data to see if that solves the problem. I will report back.

Light Manager might be a viable alternative for you if LF doesn't play nice for you. Works great without any lag issues :good:

Well, that's not exactly the news I wanted to hear lol.. I've tried light manager before and didn't like it at all. Light flow is kind of a crucial app for me. I guess I will just charge the device in the off state. Everything works fine until it gets charged overnight.
Now that you've sort-of confirmed light flow as the cause, I wonder if it might have to do with the charge state hooking. Do you have charging/charged profiles set up in light flow? If it's as simple as removing those, I could deal. I'm at work so can't really afford to test it right now.

I first endured the slowness and made a LF backup. Then 1) I cleared the data and rebooted the phone without launching LF, the phone restarted normally, calendar widget was fine, 2) launched LF and granted notification access, restarted phone, all was well, 3) restored from LF backup, restarted, all is still well and LF launches fine. Corrupted data?
At least I'll know what to do next time. For your similar issue, just make a LF backup, clear data, reboot, restore, and hopefully it resolves the issue for you. Let me know.
Edit: Regarding your question on charge state hooking--I had LF running for many years and on the Pixel 2 XL since new. The problem only surfaced recently. My Pixel 2 is also fine. I would guess that there was bad data somewhere. Like I wrote above, a reset/restore brought everything back as before.

Yeah, I went through all of that last week. I went from the newest version back to the last known stable (for me) version. I always keep a back up of the settings txt file as well as a TiBu file. My current version (previous stable) was installed from scratch.
Everything was fine for the first two or so weeks on March build. This just started after I applied the libs from the multi-touch fix. I removed that as I had hoped it would be related to the phantom swiping when scrolling (I don't game on the device) but it doesn't seem to be related the swiping. At first I thought that module was causing the issue as it started the day or two after adding it. That's the only change I have really made since setting up the March build. Not sure why it would just start out of the blue when it had been working fine for at least 2 weeks before.
I'll try some things over the next few days. First thing is going to be removing the charging profiles from light flow and see if that makes a difference.
Have you tried hooking up the charger since cleaning your data?
If removing charging profiles doesn't help, I'm going to reflash March build (removing -w from batch file) to both slots, redo twrp, elx kernel, magisk. I may do this anyway, even if removing charging from light flow fixes it.

I have connected/disconnected a generic charger twice and once connected to a PC (slow charge). So far, still all good. The problem began in late/mid March. The April patch did not solve the problem. I am using Magisk. Stock/ElementalX made no difference. I will see if the problem resurfaces.
The likely cause that there are code issues with LF. I had LF slow down regardless of charger connection so I'm curious to know if removing the charging hooks help. I'm on the latest version.
Just curious--what not go to the April patch?

I'm an "if it ain't broke" kinda guy. Everything except the phantom swipes has been perfect on March build. At this point I'm convinced the swiping issue is due to LG and therefore nothing to be done about it. I'm getting too old to flash a new ROM every week like I used to

Gotcha! Since my last post, I have connected/disconnected charger five times. Each time with several minutes of wait time in between. I have also tested functionality while the charger is plugged in. All still good.
One side note, I have noticed, with many phones, that strange and undesirable things happen when you connect the charge while the phone is mid-boot. In my situation, the LF problem may have surfaced because of that.

Well for me I was just charging normally. Hope it holds up for you. If so I'll do a clean install again and setup from scratch.
Try clearing excess text messages and cache for apps. A friend of mine had thousands of text messages and social media buildup, and the phone got very slow and buggy, especially the camera app. After deleting thousands of texts, switching to Textra, clearing the app cache for frequently used apps, the phone is back to very fast again.

Constant/Excessive Crashing

My phone can have a habit of crashing constantly, but I never get any ANR dialogs or warnings, (at all,) that could help me pin point the reason for the crashes. This has been driving me insane, I've switched ROMs, factory reset, even factory flashed my device, but it will still eventually start crashing again. So, my question is: Which logs would I need in order to pin down what is happening, and how would I obtain them?
Based on the things you've tried, I would suspect a worn out battery. Does the "crash" tend to occur at around the same battery level? You could try a complete discharge followed by a complete charge to see if it improves any.

Check to see if it could be a combination of software or some setting that is crashing with each other. You need to cover more info. Are you rooted? What monthly patch are you on?

Since first submitting this thread, I have started to suspect it is related to WiFi, at least partially. I rarely, if ever, use WiFi. However the few times when I clean flashed my ROM as a solution, I used WiFi to reinstall all my apps. After finishing the downloads I would disable WiFi, yet immediately after a crash, WiFi would be enabled, and the "WiFi will automatically turn on when you are near..." notification would be present, (leading me to believe WiFi enabling itself is what triggered the crashes.) Though not all crashes demonstrated these factors, so I don't think WiFi is exclusively to blame.

I'll have to keep an eye on that. Currently, I don't know where the batteries charge has been each time.

I apologize for not including this information in my initial post. Yes, I am rooted. I'm running Magisk v20.3, Magisk Manager 7.5.1. I'm currently on Android 9, though I believe when I tried Android 10, the problem persisted. I'm running Bootleggers ROM 4.3 Stable from 03-sep-2019 (I had run both stock and Dirty Unicorn, however Bootleggers appears to be the most stable.) Build Number PQ3A.190801.002. I can't think of any other particular info to include.
Edit: My phone also reliable crashes when opening System Settings>>Apps & Notifications>>(Selecting any particular app,) and I have crash logs for those crashes which I'll share in the even that they may shine light on the issue.

Galaxy S9 locks itself when screen is rotated. (Samsung support unable to fix issue)

First of all, let me state that I am desperate. After going through many fixes and channels, I cannot find a fix. Let me also state that I am new to the forums, and apologise if I miss out anything here. Do let me know if I have missed out any important information.
The issue: When the orientation of the screen changes to landscape, the phone immediately enters the lockscreen.
Further defining the issue: This issue occurs only when the orientation of the screen changes. When screen rotation is locked and the phone is turned on its side, the screen orientation is unable to change and the issue does not occur.

Timeline of issue (includes events leading up to issue and attempted fixes. Please note that I do not know what I am doing.):
9 March - Bought Galaxy S9 second hand from a phone shop, factory resetted prior to purchase. No issues watching YouTube videos or Netflix videos. Phone is kept at home and charged regularly.
? Apr: Phone settings are adjusted and a theme is downloaded. No issues still.
8 Jun 7:00am - Phone is prepared for daily use. App Inspector and ADB Debloater are used hide some apps (read: every form of Bixby) . Only system apps with a clear and unneeded function are hidden. Multiple apps are installed from the Play Store. One third party app, Ymusic, is downloaded from a website.
This app has not caused any issues on 3 other Samsung devices (S7 Edge, Note 9, S7). APK extractor is used to extract Video Editor from a Galaxy S7, and it is installed on the Galaxy S9. The S7 does not have any issues.
All apps downloaded are already present on the Galaxy S7 with no issues except for a remastered version of a game called "There Is No Game Jam Edition". The older version of the game has no caused any issues.
8 Jun 12:13pm - Two videos are watched on the YouTube app in fullscreen with no issue. Soundcloud is visited. Visited drugs.com and reddit.com. Watched more videos on YouTube app. Tested smallest possible delay in double pressing left menu button to switch between apps (like alt-tab but for Android). Discovered that while the S7 has no noticeable delay, the S9 requires more than half a second to pass after the first press in order for the second press to cause the next app in the list to be selected. If the two presses are back to back with no delay, the S9 simply stays on the app selection screen.
8 Jun 2:13pm - Watched a video on YouTube app. Turned screen to landscape, and phone locks itself.
8 Jun 2:58pm - Engaged Samsung official support in remote control session. Samsung tech used General Management in settings to reset all settings twice. Tech also removed lockdown mode from power button menu. Tech uninstalled some possible culprit apps: Ymusic, 1.1.1.1, Malwarebytes. Tech guided me to boot into safe mode. Issue persisted even in safe mode. Tech instructed me to factory reset phone. He also stated that if the issue persisted, I would have to send it to Samsung's service centers for an inspection. I expressed concern that I may have caused the glitch and that following the same setup procedure as before would simply cause the glitch to return.
Note that I also do not have access to my laptop to "debloat" , as I have sent it for servicing on the morning of 8 Jun. In addition, I have developed some sort of swollen infection on one of my fingers that makes typing into a command prompt to "debloat" not just uncomfortable but also very unhygienic (I did not see pus until this time). Writing this on a mobile device, on the other hand (or my thumbs) , is OK.
8 Jun 6:29pm - Posted this issue on Samsung Reddit and twice on corresponding Discord. Posted on Google Android help forum.No replies on all. Messaged Android enthusiast friends (who may/may not be technically competent). Friends suggested deleting One UI cache and data. Issue persists.
9 Jun 10am - Posted issue on Tech Support Reddit's live chatroom. Some members suggested posting to XDA.
9 Jun 1:34pm - Discovered that minimum delay between presses of left menu button to switch apps is now insignificant.
are you sure all you did is debloating? because I did it once and I got zero problems, beside debloating shouldn't cause your phone to do that far. and non of the apps you mentioned above could cause the problem imo.
My suggestion :
- just use custom rom, if you want to stick to OneUI but got no Bixby and unnecessary Samsung apps or what so ever just flash Alexis ROM (OneUI 2.1 already). It is a bit tricky, since you have to unlock bl, and flash twrp and other thing. but it worth imo.
- if not, just flash again the stock firmware and redo the debloat
I am very sure all I did was disable and hide some apps with obvious purposes (such as Bixby) with ADB. While I am open to the possibility that something I disabled caused the issue, it makes no sense that a few hours would pass before the issue appeared. All I did in those few hours was watch YouTube videos use Ymusic, so I could not have possibly picked up any form of malware (which would be blocked by Malwarebytes anyway) or made any changes to break my system.
For now, I am going to factory reset my device and test landscape orientation after disabling each app while simultaneously praying to the Android gods that nothing goes wrong. Alexis ROM looks like the solution I am looking for, but unfortunately I know my limits and installing a custom ROM is beyond them.
This is a problem with my stock android s9
I'm frankly just about to give up. I factory resetted the device and redid installing all the apps, set them all up and got the settings in order. Guess what, the same exact glitch occurred out of the blue. Along with two more- a noticeable delay when double pressing the overview button and the lock screen clock settings being un-clickable. I'm running out of patience and hope for this device, but then again all the others I have are equally broke. Pity, was hoping to start working food delivery, too.
UPDATE: With guidance from a friend, I have used Odin to flash a friend's functioning copy of Android 10 on my device. I am going to configure it as usual and pray that nothing goes wrong. Will update here in about 24 hours' time, the time it usually takes for the glitch to appear. It should be noted that yesterday, I was watching videos on Landscape mode just fine until I decided to finish up changing my settings. That was when the glitch occurred, so I highly suspect that some setting I changed is causing it.
UPDATE 2: After flashing my friend's ROM, I went on to install only 1 app (App Inspector) and remove only 4 system apps while paying attention to any changes(disabling Always On Display broke my lockscreen clock settings so that was nice). Still, I could rotate the phone to landscape just fine. It was when I pressed the setting "lock home screen layout" that the glitch occurred. On one hand, this adds up, as the glitch occurred soon after changing this setting yesterday. On the other hand, I do not recall changing this setting the first time I configured my phone. I will experiment further and update this thread.
