Lock Screen "Try Again In..." countdown even though I never failed - Android Q&A, Help & Troubleshooting

(Sorry for posting this to a general forum, but I figured there's a good chance this issue is not model-specific.)
I noticed some strange behavior (henceforth referred to as "the behavior") on my stock 4.1.2 T-Mobile GN2 lock screen (numeric PIN) recently. Twice, on random occasions, when I pressed the power (right-side edge) button to wake up the phone, before even touching the screen I immediately caught the "Try again in X seconds" in the middle of its countdown on the lock screen, just below the clock. The first time the countdown was at about 1s (almost done), and the second time it was at about 10s. There is no way myself or anyone else had physically tried and failed 5 times. Both times the phone was sitting near me face-up on a table, nothing else touching it, and nobody else around.
The first thing that came to mind was some kind of malware. But if an attacker is already "inside" so to speak, why would they want or need to brute-force the lock screen? And can the lock screen even be seen from "within"? I thought it was only relevant to physical access (on-screen or USB storage).
Does anyone know details about the lock screen mechanism to say what on earth this could be? Google search returns a few similar reports but only in dead-end threads. Even though my device is stock I figured this question may be above and beyond the usual users' forums, so I am hoping the expertise at XDA can help. Thanks in advance.
Here are more details that could be relevant:
- The device works fine otherwise.
- I saw the behavior happen randomly twice in the last 24 hours, and I had rebooted in between. Prior to that I had never seen it. I cannot recreate it at will.
- WiFi and GPS were set to off. The first time the phone was on AC charger (mains, not PC), the second time it was on battery.
- There have been no major changes (that I know of) to my phone. I have not even installed any new apps in the last few weeks.
- When I try failing the lock screen 5 times on purpose, I get the "Try again in X seconds" countdown under the clock AND a popup with OK button saying that I failed. In the behavior, there is no popup, just the "Try again" countdown.
- I do not notice any other suspicious activity like unfamiliar processes or unusual bandwidth usage, although I do not have the tools or know-how to examine individual packets or anything like that.

[Q] Random strange things happening

Ok so I want to convey all the relevant information without this being a mile long.
I have a o2 UK SGS2 running on a 3 sim. I have flashed on Lite'ing 6.1 with ninphetmaine 2.0.5. Up until the following, everything has been 100%.
This morning I downloaded Destinia and played it for a while. Before quitting I took a quick look at in app purchases to see if they charge ridiculous prices (they do). I'm not interested so I quickly spam back to close everything. This is when **** ****s up. OS becomes unresponsive immediately and I have no choice but to pull the battery. (power menu disappears instantly, no registered actions from soft keys or menu button in OS). No change on reboot.
I try reflashing Lite'ning. Mostly no change but I got the chance to get into task manager and uninstall Destinia/Launcher Pro.
I reinstall launcher pro, and now it works most of the time except:
1. Quite frequently the voice action app will load itself, and the unlock notification will pop up.
2. MTP notification will appear occasionally and phone will act like it's plugged in
3. Random Launcher/OS crashes. Sometimes screen on but no response from apps or OS. Sometimes screen won't turn on at all, just softkeys and darkness.
4. at first unlock after boot, camera makes standard focusing sound.
5. on boot, little popup dialog will read "in app purchases not supported in this version of android".
Really I doubt there's going to be any solution other than "wipe and reflash" but I'm really interested if anyone knows what would cause all these problems.
Cheers

Whatever that means looks to be the source of your problem..

what this means is that pressed back from the game's in app purchases screen, back to the main menu and then back to the Launcher, I'm sure everyone has done basically this countless times.
Fine but my dictionary defines spam as a different meaning .
But as posted that's where it all went wrong for whatever reason .

Right I wipe-flashed stock 2.3.5 and it's STILL doing this. Voice actions popping up at random, all sorts of apps crashing and hanging all the time.
This has to be a hardware problem now, right?
just a stab in the dark but run a virus check.
I've never had a virus in my life, but I checked anyway and nothing.
Right so I've been watching my phone today. It's still doing random voice action popups. If I leave the phone on standard standby it will be fine for a while. It will then randomly turn on the screen by itself. The screen will stay on, if i leave it long enough the whole thing become totally unresponsive. If I press power the phone will wait a few seconds, then restart. If I don't touch it, it will just restart on its own eventually.
Can anyone recommend at least, some logging software that will let me look at the underlying OS and see what's happening when this is going on.
Is there any possibility your phone also goes to car-mode by itself?
spare parts app??
Your phone is more or less doing the same thing as mine is. It's a hardware issue from the seems of it. The voice command thing is from a dirty pin in the USB connector part which apparently isn't that hard to clean, for users in the thread below it actually helped to solve the issue. But my persisting issue is the unresponsive screen and power button causing an active screen to dim out and making the screen unresponsive..

Im getting random voice talk and mtp etc. phone is all ovr the place. flashed litening and nimphet last week and seemed fine. used mhl hdmi cable and problems seemed to start from there.

Read your thread http://forum.xda-developers.com/showthread.php?t=1278790 and your problems are down to the letter the same. I've resigned myself to it being a hardware fault and put in a service request with samsung. Wish I had better news.
Yea me too. My issue is that my SGSII was manufactured in UK so I'm at odds seeing as how I'm in America. The people at the Samsung call center referred me to the UK number so I guess I will have to bits the bullet.

New, Stock Phone Begins Locking Up ~30 Sec. After Boot; Req. Factory Reset to Fix

Last night I was reading Twitter before going to bed when I noticed that my GPS kept ticking on and off after I'd posted an update (I let my Twitter app access GPS to assign my location to tweets). Thinking that odd, I rebooted.
Talk about the reboot from hell.
Approximately 30 seconds after booting back up, the phone locked: I could tap buttons and feel haptic feedback, but no changes to the screen occurred. I eventually got the bright idea to lock it and unlock it; pressing the lock key blacked the screen, but pressing it again did not bring the screen back. Scared, I eventually pulled the battery and started up again.
It happened again. And again. In the midst of all this, I slowly learned a few things: it wasn't tied to any of the new apps I'd installed (I had enough "functional time" each boot to uninstall a couple of things), it wasn't tied to internet connectivity or GPS (I had time to turn both off), and the SGS3 has a dev option to monitor CPU usage of various apps/threads. That little HUD, which overlayed everything else, would remain updating through a lockup, and I found that a process named "df" was starting up and immediately sucking up the entire CPU and not letting go.
I eventually found that it worked the processor so hard that the phone would overheat if left alone and "soft reboot" (OS restarts, but no Verizon/Samsung loading screens), so I was able to at least stop pulling the battery!
Finally, I turned it off and let it cool down for a few hours whilst Googling: no results anywhere for a similar problem or regarding the "df" process. Turning the phone back on after its reset didn't help at all. The lockup time was so quick that I couldn't even initiate a factory reset--it would lock up in the midst of preparing to perform it!
I eventually restarted it into the bootloader (meant to go for recovery, oops) to poke around and got a really scary image: a "Custom" screen before the bootloader starts that the devs are saying means that system apps/files have been modified. Now, since I don't have root yet (no hacking/voiding warranty JUST yet), I am not ABLE to modify system apps, which means that something got tweaked all by its lonesome, and THAT isn't supposed to happen. It was probably what was causing the lock, though--some driver somewhere that's supposed to say "Processor, don't try to calculate pi to infinity" got hosed or whatever.
I eventually got into stock recovery and was able to initiate the factory reset from there without the use of the actual OS (thus avoiding the hard lock). The phone rebooted fine, let me sign into Google, and spent the rest of the night redownloading apps. It's fine now.
EXTREMELY worrisome. Possibly a hardware fault with the EMMC chips holding my OS or something--there's not a lot that can knock out system files on a non-rooted device. At least it doesn't appear common, insofar as all my Googling leads to no results at all.
Any ideas as to what the heck happened?

[Q] GS3 waits up to two minutes before placing a call

My stock Verizon GS3 waits a while before it makes a call.
I can click on a favorite, dial a number directly, or select someone from my contact list. When I hit dial, the phone does nothing for up to two minutes. It remains completely usable (I can surf the web on 4G, open and close apps, whatever). Just no phoning. Then, after a delay of anywhere from seconds to two minutes, it will suddenly dial the number. From then on, it works the way it should. The next time I try to dial, assuming I have waited a bit, it all happens again. If I try using the phone right away after it has sort of "woken up" to the fact that it should dial numbers, then I can continue to dial new numbers without a delay. Only after it sits a bit does it get stuck again. If I try to hit the "dial" button a number of times (aka, retry dialing because the phone isn't doing what it should) it queues these requests up and once it gets unstuck, it will dial all the numbers one after the other.
This issue also affects two other widgets (and nothing else that I can ascertain). These are the Assistive Light widget and the Negative Colors widget. They behave the exact same as the dialer. I can hit them as many times as I want, and it will simply seem to ignore my button presses. But, after a delay of up to two minutes, suddenly every button press I hit will be queued up and executed all at once (causing the screen to flash negative and positive, and the flash to go on and off a bunch of times).
I am running go launcher and the stock android 4.0.4 on Verizon.
Some specific questions:
1) What should I look for in the logs to indicate that the phone is placing a call (or handling the Assistive Light request)? I have tried to isolate the portion of the logs around when this happens but they are so dense I have no idea if I am even looking in the right area.
2) I occasionally see "VoIPInterfaceManager" referenced in the logs, but as far as I know I am not using VoIP (I had skype installed at one point but then deleted it when this problem started thinking that maybe it was interfering, but to no avail). Is this in any way relevant?
3) I have an extra SD card installed (yanked from my old DroidX). Could that be the issue? I just pulled it out again, but the phone does not always misbehave, just sometimes (say, 75% of the time) and it just happens to be playing nice right now even before I pulled the card so I don't know if it helped or not.
4) Is there anything I can do to start diagnosing this issue (i.e. apps to try to diagnose what is going on, developer modes to put the phone in)? How about anything people can suggest to even start narrowing down what the culprit may be (hardware? downloaded app? os?)
Thanks, and sorry for the long posting. This is making me nuts.

So several days have passed, and it appears to still be working. I suspect the sd card was the culprit. No idea why. But I am a happy camper again.

A different screen issue: Graphical glitching when scrolling: locks up phone

Hello,
So it's 6am here in the UK, and I went to check my phone as I'm waking up to find that the screen is acting up! It's been unplugged all night, and the night before I was searching google before just locking it and going to sleep. Before locking the phone, one of the web pages (atleast what I believe) was acting up, causing *their* page to make this weird grey, green and red lines over a chart I was looking at. I took no notice, went to sleep.
Turns out it's not the web page: scrolling in google, and most other apps now (including the settings) causes this weird glitching to occur.
Pretty much any UX and UI scrolling causes this, with the only solution being to close the app - it locks up the phone while the glitching animation occurs.
Any screen shots I get now are completely grey - really odd!
Thank god I am still in my 14 days - going to send it back.
What do you guys think? Return the device and get a different handset all together, or try again with the Mate 20 Pro? Happy to experiment with this if any of you want to know more.

Scrolling through google: streamable.com/wnjq8 (Big problem)
Scrolling through reddit: streamable.com/hdh3u (fineish)
Scrolling through settings: streamable.com/1oyhl (Oh dear...)
*****EDIT******
So my phone specs are as follows:
Mate 20 Pro 128gb 6gb edition /w a 128gb nano sd card
Model: LYA-L29
Device: HWLYA
Some settings I had enabled when this first occurred:
I had the screen set to WQHD+ instead of the Smart resolution: since turning this back on, I have noticed the bug to occur less, but still occurs.
I usually have the notch set to default, as I quite like it, but since this has occurred, I have got 'hide notch' enabled
I do have the on screen display setting so I can see the clock when its locked.
I have restarted the device many times, sometimes I restart, I notice the gluegate issue, but it never occurred while using the phone, only while shutting down (green edges)
Chrome seems to be one of the main apps this occurs on, particularly when scrolling - It can even crash chrome too. Oddly, reddit seems fine.
When closing apps via the bottom right corner and swiping up, this bug has never occured.
FYI I've only had the device for about 2 weeks, (just under thankfully) so I'm hoping the new handset doesn't do this!
So I closed all the tabs on the phone, and also enabled 'eye comfort' mode (should have really done this one at a time) and it seems to have cleared up the issue in everywhere but chrome. It's nowhere near as bad, but not something i'd settle for. The current isse now is that chrome sort of stutters-ish. I'll post some more experiments in a minute.

Yes many times - sadly didn't help much.
The issue came back, so I'm currently talking to three to send out a replacement
So my new handset arrives on Monday: so I got the weekend to experiment with this handset. Hopefully possibly help some people in the future. I'll post some specs and models later along with some other videos.
Has your new unit solved these issues as I have the same also where the screen locks up and shows the image or something like a hundred times. In addition to the grey screen

Question Random reboot - any Pixel 6 (non pro) users affected?

Wazzup.
Over at the Pixel 6 Pro fair, we have quite the number of people having problems with random reboots. We are trying to narrow it in - Android12? Pixel 6? Software? Hardware?
So - anyone here with the same set of problems? Or does the Pixel 6 not have that kind of issue?
For reference: https://forum.xda-developers.com/t/random-reboots.4353231/
I have gotten several random reboots as well. 256gb seafoam pixel 6. In particular, I was using "Frep" automation app (unrooted, used pc to start server) to do repetitive image searches in a game. Also the phone was sitting on a wireless charger while doing this. I noticed my phone felt pretty warm, wonder if it could be overheating?
Could be a naughty 3rd party app. Have you tried safe mode?
I posted this here:
P6 Bluetooth Problems
My p6 will see most some of my Bluetooth devices (laptop, tablet, TV, earbuds) . It pairs with the earbuds, but everything else it will try and pair, usually does not. If and when hen it does pair, that pairing is dropped dropped within 5 secs...
forum.xda-developers.com
My random reboots (or crashes that forced me to reboot) almost entirely stem from the wifi+bluetooth implementation. I found a sure-fire way to crash it during setup. Without word vomiting here, connecting the P6 with and to other devices has proved more difficult than any previous Pixel (for me).

Not yet. It's also hard to "force" it (the reboots, I am not able to replicate it manually). Yesterday it just randomly happened whilst the phone laid idle next to me, thrice at the morning, about one time through late afternoon, then one time evening. I just notice the screen lighting up, then the Google logo comes, meaning the phone restarted.
I'm also pretty sure that Bluetooth/Wifi settings differed when the reboots happened, ergo at some times bluetooth was on, then when it rebooted, bluetooth was off. At no time when the reboots happened had I a bluetooth device connected. WiFi was online though, all the time.
What all the reboots have in commong though (at least the ones where I am concerned), is that the phone is just laying next to me, or somewhere, being in idle - doing as far as I know, nothing. It never happened when I used the phone or put it under load, so my P6 never "crapped" out under me. That's why I am not that concerned about this as of now, but it's certainly a nuisance to unlock the phone every time with my darn pin.
(Concerning 3rd party app) - I'd say that's unlikely. I copied my files over from my Pixel 4 XL and have not yet added one singular other app to my P6 Pro, so it should have gone naughty before my transfer over.
Hi! I experienced a big crash on the pixel 6. When I was configuring telegram, the app crashed and then the screen got black. After a minute it rebooted to the Google logo with a loading bar underneath. It was blocked in that state, but I could reboot it with volume up + power button.
I was pretty scared as the usual button down + power button didn't do anything lol

Odd. I never had a problem whilst using the phone, my phone only rebooted when laying idle (even though today I had no reboots at all, alas I didn't use the phone much, maybe 2h SoT without any heavy lifting).
Something in android 12 is bugging around, maybe we have to open support tickets.

I just talked for a while with a Google rep and he said that they are not aware of any reboot problems, no people over at Google Forums have reported such a thing. "We do not monitor Reddit or XDA" - so he said he opened a support ticket to the responsible team and they would look into it, he also asked that I / we report/feedback this under -> Settings -> Tips & Support -> Feedback.
We also talked about a lens flare problem, that at least the Pixel 6 Pro has. If you shot some photos where the sun is directly shining into the camera, you might want to re-check them. Most of mine have either some sort of big circular green dot in them, or a big beam of light like in a phone with a very bad HDR processing. It seems to be some sort of software glitch, he also reported that.
So hopefully those things can get fixed.
This was the follow-up email:
Thank you for contacting Google support.
This email is regarding the chat conversation we had earlier today, I'm sorry we weren't able to complete it. Hence I wanted to follow up via email to ensure all your queries have been answered.
Please re-launch the camera app and check if the issue is fixed.
Please be assured our developer team is working on this to fix it as soon as possible. We would really appreciate your kind understanding as we work on this to fix it for you.
If there is anything apart from this that needs clarification, please feel free to reply back to this email. I'll be more than happy to assist you.
Thanks!

I'm having similar restarts while phone is sitting on a table doing nothing. Tried a factory reset and was fine until overnight on charge and it happened again.
Also have had a few times where wifi has stopped working for some reason. Not sure if related.
Not had any reboots but quiet a few app crashes in especially FB will be scrolling away and bang just closes also Amazon app ,
Well that was interesting.. When it rebooted that time, it gave me an error screen saying it could not load and may be corrupt. I had two options, try again and factory reset. Try again got me back running, but I'm wondering do I got as defective device now.. or if it's software related.
So after a lot of messing around, I think I have narrowed down what may be causing my reboots. It only seems to happen when I am using "Frep" to play macros on a game while charging my phone.. the phone gets pretty hot, and reboots when I tap the screen or try to swipe home or recent apps. Maybe its overheating, or maybe its "Frep" playing naughty.. but Frep did work perfectly fine on my old $200 used Nord N10 5g. Will update if it reboots while not doing this.
no reboots or crashes so far, not doing any gaming - but using phone for email, surfing, whatsapp etc and also a work profile for MS outlook and teams.
I have/had similar issues with my Pixel 6 (128GB - europe unlocked).
I was transferring old data via cable from my old (Xiaomi Mi A1) to the Pixel 6. This resulted in sluggish performance, crashes every 15 minutes. The crashes would randomly occur and behave mostly like this:
Try to unlock phone with fingerprint sensor
Fingerprint sensor lights up, nothing happens, no haptic response
Swiping up to the PIN entry. Enter PIN and hit enter. Nothing happens. Now freeze.
Screen turns black and it takes phone to reboot on average ~7minutes
Factory Reset; Installed apps manually (standard messaging apps, no games etc), better performance, problem persists
Factory reset; boot into safemode. It now took way longer to provoke the issue. But it still happened.
After this I contacted the customer service and they will provide me with a replacement. But now after a night of idle, the phone was working for 3-4 hours without any issue at all with most of my apps installed. It just now went into a random reboot (could only notice because it asked for PIN because of the reboot). But not the 8 minute blank black screen type of reboot.
I am really unsure what is the issue at hand here. But have to say that experience is less than ideal.
Mine just happened last night, not charging or running anything 3rd party apps (all from App Store). I tried to use the camera after eating dinner and noticed that double clicking power button doesn't open the camera anymore. After unlocking the phone it appears that the phone has restarted.
Is anyone running Private DNS on their system like Adguard DNS or NextDNS? I did some searching and people reported some private DNS were causing Android to crash. It was suppose to be fixed in previous Android versions but it could be back again.
I haven't noticed any random reboots (and the lock screen will require a pin to be entered after reboot and says this on the screen, so you should know the phone rebooted). I've had the P6 since the official release date. In fact, I haven't restarted the phone in days.
I run a wide variety of apps. Some from the Play store and some sideloaded. I think that any reboot issues are probably app related. Remember that A12 is very new and the are surely still some compatibility issues that app developers haven't found/fixed yet.
