[Q] How do I prevent USB file access at lockscreen? - Nexus 5 Q&A, Help & Troubleshooting

In previous versions of Android, when I plugged my Nexus 5 into my computer, if it were at the lockscreen I had to unlock it before it would show me the files on the sdcard. Now, though, running 4.4.2, I notice I no longer have to do that. I can just plug it in and at the lockscreen go to my files. While convenient, especially for transferring large files, I'd rather a thief not be able to do this. I can't find any setting for it though. Any ideas?

Have you got a pin code or just swipe?

Also on my N7 2012 w/ 4.4.2, also using pattern, I can't access the files via USB until I unlock. Same pattern too.

This is what mine does on both windows and linux.
Plug in locked .. device shows but is blank. Upon unlock, directories become visible.
If I lock whilst already connected, connectivity is not lost.
Not sure why yours acts differently. Would be pointless having a lock if you could still get data
There is no setting for this. Maybe you need to wipe ? If unrooted, backup with helium

+1. I just tested mine on 4.4 and 4.4.2 and have the same behavior. Pin lock.

And this is exactly what my n7 does. But my n5 doesn't. I can immediately access my files.
Franco kernel but was even happening on stock. In fact thinking back my n5 has always done this since I got it a month ago.

There probably was a time when it worked. Probably should do some testing with a full wipe. Maybe its an app

With mine on 4.4.2 it locks device access until pattern lock is put in. Perfect. It sounds like you have an app interfering or need to do a reset.

Ugh. Even with titanium backup I hate doing wipes. But I suppose if it fixes it then it comes back when I restore then I'd know it's an app. I'd hoped this was a known issue.

Take a nandroid. If wipe doesn't fix it at least you can full restore

Partial reboot issue

Hello all.
Hope you guys can help me figure out a little problem I've been having with my nexus.
Its basically quite simple. I've had this problem with both the infin1ty and oxygen roms.
Basically my phone randomly jumps back to the pin entry screen. Its not a total reboot, it Just goes to the pin entry and its like I just restarted the phone again.
Its happened mostly when the phone has been asleep but also one time when I was using it to browse the web. It just jumped to the pin screen asking for my sim card pin code. Its never a full on total reboot.
I don't know what could be causing the problem. The only connection between the two different roms I'm using is the fact that I use the same netarchy kernel, with set cpu and proton voltage app.
I figure if I didn't have my sim card pin enabled then the phone would just connect to the network automatically and I would be none the wiser but due to security I always have my pin enabled. So its quite annoying that when I go to wake my phone to use for something I see the pin screen waiting for me and no signal. I hope some of you guys can help me figure out what's causing the issue.
Thanks in advance

Hey, what do you know ...I'm not the only one. That's comforting at least.
I just switched to a new rom about a week ago now and same issues...it seems whatever this thing is, it runs real deep. Very annoying now.
Sent from my Nexus S using XDA App
Having the same issue - it happens irregardless of which custom rom I use. Doesn't happen often, though, like once a week and usually when I'm not using the phone. Have no clue why...
^^^it must be that we are just a small unlucky minority or else others would probably have found a solution by now.

Really? Interesting...might try that and see. Thanks for the tip

As a general note you should always clear any and all sim card locks before putting them into any smartphones. They almost all use different protocols to communicate with the sim card and without clearing the pin before insertion can cause corruption and that's how these errors arise.

Charge state not changing...

Last weekend, I noticed that my phone e was no longer logging changes in charge state with battery indicator pro. I thought the program was the problem and removed it. The problem remained, so I decided to see how far it went. Even with the phone off, plugging it in won't make the white battery appear on the screen, even though the phone IS charging.
Without performing a factory reset just as a test, can anyone think of any reasons this might happen?
At&t version
Gingerbread 2.3.4 OTA
Not rooted, not unlocked
Bought new in October.
Thanks in advance!

Sounds like a bad USB port. Is it recognized by a pc? Can you transfer data?

A-ha! You are correct! I hadn't considered that branch of my troubleshotting flowchart.
My phone doesn't recognize that it has been plugged in to a PC.
Thanks for the help!
I will research remedies for this problem.

Phone rebooting

Hi, twice today my phone rebooted. Once on a call and when it booted back up after I put phone on charge and left it for 5 minutes and it rebooted again. My phone is all stock on ART runtime. Any ideas? It did happen few weeks ago too while on a call.
Thanks.

without any kind of logs, nor a last_kmsg, it is just a guess why your phone rebooted. since this guess is as good as any other guess, i say that your phone rebooted from fear of dinosaurs.
How can I get the logs that haven't been eaten by the dinosaurs yet?
Sent from my Nexus 5 using Tapatalk
Disable ART it is experimental right now. But with out logs finding out why is a guessing game and an uneducated one at that.
Sent from my Nexus 5 using Tapatalk
do you have root? you can run a last_kmsg after a reboot. the device automatically saves this after a reboot that you didnt do yourself. this will show why your device rebooted.

[Q] How do you turn on the cover warnings?

I received the new warnings about the back cover and charger connection was not closed the other day and hit do not show me this message again. After thinking about this a bit, I want to turn them back on so if I do indeed don't have the cover on correctly, it will not mess up my phone if I get water on it.
Does anyone know where to go in settings to turn them back on? I have not been able to find them so far.
Thanks!

i don't think its a phone check, it is a reminder for you to recheck the covers.
if the cover is not correctly installed, i don't think the phone knows.
Either way, I need to find out how to turn that back on (uncheck the do not show again) so it warns me again..

I also turned off the reminder to shut the charging flap and want that enabled again

Yes it's just one of those notifications that teaches you about the phone. It does not know if the cover/port is open or closed.

I would still like to be notified anyhow because I keep forgetting to shut it and put it in my pocket that way

I'd like to know also. Probably could figure out the app with a catlog. I know a hard reset does it, and reseting TouchWiz does NOT. I assume it's s Samsung app.

Phone Locking Up

I'm hoping that this isn't a unique problem just for me but this is literally the first time I've had this problem. Depending on the use of my Note 5 will determine if I can even unlock my phone the next time I turn it on. I'll go about my usual use of any phone should be able to accomplish (browsing Instagram/Facebook/Chrome/Email/Pinterest/etc.). After a little while it become noticeable that the phone is starting to slow down considerably if I continue to use it. However, the one that really grinds my gears is I'll do my typical browsing and then lock my phone, put it back in my pocket. Something we all do, however, the next time I go to pull out my phone I can't even get the screen to come on for sometimes five minutes. I can hear it thinking with random sounds of the lock screen either responding to my fingers touching the screen or the un/lock sound but nothing happens. Sometimes, I can see the screen and all the notifications that I want to check on but nothing is happening. Sometimes, I'll double tap the home button to get to the camera shortcut programmed to it and sometimes the camera app comes up like it should but it is completely unresponsive.
So the steps I've tried to resolve the issue:
Restore to Stock ROM
Different ROMs
Even leaving the Stock ROM alone and just seeing if it still occurs
I'm just not sure what to try next. There's a chance the problem could be a memory error that's occurring physically but I'm not 100% sure.
Attached is my Note 5's current state of customization. Any help with this would be very very much appreciated.
Thank you
Giving a slight bump here. Does no one else have an idea of what c could be wrong?

Have you removed or disabled any system files? Also have you tweaked the kernel in any way?
I will say that I've had issue with v11 of that kernel you are using. I bounce between v4.1 and Sky-high v4.5 depending on what I need my phone for that day.

I will give those a try. Thank you!
