Long delay unlocked after PIN entered - Samsung Galaxy J3 (2017) Questions & Answers

Anyone else have this issue? Enter PIN and press "OK" then phone takes 5 seconds or more to unlock, just delays doing nothing for 5 seconds or more. Sometimes 10sec and sometimes screen just goes back to sleep
*More: reloaded factory F/W, no lag, nothing. Then load TWRP and SU/Root, no-encrypt file. Lag. Big time. Something around the rooting...

I guess it's caused by super su..i have facing this problem before. So i change rooting method with magisk & the problem is gone.

I have magisk and still face this problem...

Same problem using su

Occasionally get locked out upon waking up Nexus 5

Sometimes when I press the power button to wake up my phone, I immediately get locked out for a short period of time as if I entered my password incorrectly multiple times. I have to wait before I can enter my password for the first time. There is no popup saying I entered my password 3 times incorrectly and the locked out time is very short (about 5 seconds). I'm running rooted stock 6.0, and the only app I can think of that could possibly affect my lock screen is gravity box's quick unlock for pin passwords.
Has anyone experienced this before and know how to fix this? It doesn't happen very often, so it's not too much of an issue, but I would like to fix it if possible or at least know why it happens.
Thanks in advance!

Random Reboots Nougat

I have installed Italian OTA Nougat for about a week with clean install (no root).
The phone have suffered 3 random reboots in 5 days. I can't find the culprit of it. It's bizarre that after every random reboot there is a completely white screen after I insert the sim code and unlock the phone. I must press home button in order for the phone to be usable again and go to home screen.
I guess that the obvious answer is factory reset it again, but i really don't have the time to set it up again from scratch. Any ideas or suggestions? It's there a log of the phone that I can use to find the culprit? Thank you for your time
Block this app causes the issue with the white screen. I have uninstalled it and i how Random reboots stop too.

[Question] Android randomly reboots, but doesn't ask for SIM pin code on reboot.

For the past few years I was starting to notice that every now and then my phone would just reboot for no reason. (Interval being like once or twice every 3 months, and no reason meaning no noticable reason (no software update, no freeze, no low memory, no extended use etc.)).
And this isn't even a normal reboot, because if I hold the power button and then reboot my phone, when it's done I am prompted to enter my SIM pin code, and then my device pin. However on these random reboots, the phone only asks for the device pin, never the sim.
When the random reboot happens, my phone vibrates as the screen fades to black, and soon after I see my service provider intro and the device and android specific intro, and then the phone asks for my device pin.
This was happening with my older phones, Xperia GO, Z3 Compact, and now it is also happening with XZ Premium. On the XZP, I have fingerprint detection on, however on boot I have set it to always ask for the PIN, and disregard FP detection on boot. That's why I know it rebooted, even if I don't notice it happening on the spot.
Anyone got an idea why this is happening? Always have latest available firmware installed (vanilla OTA android), and also latest app versions. (Also I don't usually shut down or reboot my phone, I leave it on "forever" most of the time and just charge it at night. Most recently I put it on charging and the phone rebooted when I plugged it in.)
What I want to know: why the reboots are happening, how to stop them, and how to force the system to ask for SIM pin when a random reboot happens (without it I lose an extra layer of security if this glitch happens).
1. First remove sim and look your problem solved or not?
2. If not I suggest you to flash your firmware

Random Restarts After Rooting

A week ago I rooted my note 20 ultra. Everything works really well. The only problem I have is the random restarts. Sometimes when I use my fingerprint unlock the phone just crashes into the boot screen and then boots back up to the home screen. Whenever the prompt comes back up to put in my pin, I put it in and the phone crashes again. This happens a few more times until it stops occurring and I am able to log in perfectly. I believe that the issue could be occurring due to a lack of memory, but I would like some second opinions. What do you guys think?

Pixel 2 XL starts, unlocks, then reboots

My Pixel 2 XL has an issue where the phone will boot and sometimes reboot randomly during the boot process. Other times, it successfully boots. When it does, all is well as long as the phone remains locked. Once the phone is unlocked however, it freezes after a few seconds and the reboots. When the phone finally unlocks without a reboot (seemingly random), it has no further restart issues and is good as long as it remains on (often weeks at a time).
I suspected it was an app causing the problem and tried booting into safe mode, but with the same result. Perhaps something that runs at startup is triggering the issue? The phone is quite old now and it has been dropped a fair number of times, perhaps it is a hardware problem, but it seems strange that the phone is fine as long as it can make it past whatever is happening at startup.
There are two things that I can visibly see happening at startup. The google assistant icon appears in the notification bar, followed by the voicemail icon.
Any ideas on this?
