I want to use a Samsung device (4.1.2) within WPA2-Enterprise. When I install a certificate in order to connect to the RADIUS server, the phone immediately wants me to set up a PIN to lock it. I can't disable this setting afterwards, only by removing the certificate. Which locks me out of the wifi.  Is there any way to deactivate this behaviour of android and to keep the phone usable without entering a PIN to unlock it?

:     The type of lock that's acceptable may be predetermined by your system   administrator.   Where I can define what's acceptable? I can regenerate the certificate if needed.  So I can use slide lockscreen again.  (I'm using CM9 RC1, Android 4.0.4)

On my CM9 / ICS 4.0 phone, if I incorrectly enter the drawn pattern five times in a row, it locks itself for 30 seconds. I can't enter any more passwords, but I can click a "forgot my password" button and enter my Google Account password.  On my rooted 4.0.3 tablet running a custom ROM, my lock screen is set with a numeric PIN. If I input it incorrectly five times or more, it locks itself and I can't enter any more passwords.   I'm not offered the option to enter my google account password to bypass this, although I have configured a Google account on the device.  I want to activate the "I forgot" button in order to enter my Google Account credentials. Is it possible?

I am trying to make my main desktop be able to reboot right into the desktop without asking for a password, but I still want to be secure when I'm accessing it remotely. No one is ever going to physically touch my PC except me, but security is security dealing with Remote Desktop.   How can I enable RDP without having to type the password locally?

We have a very large wifi network at Stack Exchange, and the primary guest network is tightly locked down.  Our firewall rules permit essentially just http/https and vpn connections.    When our Android phones connect to the wifi, they show good coverage but the WiFi icon never turns from grey to blue.    What is the Android phone checking to make the grey/blue wifi icon decision in JB 4.2.2?

I'm using a PIN code to log on my computer. However, Num ⇩ is always turned off, even if on before shutting down my computer. This is quite annoying as I always have to retype my PIN.  I've tried the suggestions  (same as ). But with no result. If I don't enable num lock on log in screen and use the numbers above the normal keys, num lock turns on after log on. Then it's too late, unfortunately.  So, how can I make num lock enabled by default when logging in? Thanks.  Edit: While I still want to solve this, I've figured it is not such a big problem. I will need to press some key for the "enter PIN screen" to show, and using Num ⇩ works and enables num lock. But then, still annoying if the computer was only locked (with num lock on) and I turn it off, hehe.

Pressed the onscreen button on my s6 edge this afternoon and a strange new display swipe screen is showing up - picture included. I have no idea where this came from and I have to swipe it just to get to my pin lock. I've checked my apps, my settings, my locked screen, I've disabled some of the apps I thought it could've been but to no avail. Does this look familiar to anyone, and if so how do I get rid of it? It's eating up my battery life.

For hardware reasons (My menu key doesn't work) I can not add an APN via settings. I read  about using sqlite and  about using code. But I need a more convenient way to do it. I need to do it using adb.

I have played with Android device manager and I have blocked my phone. I have deblocked but everytime my phone enters into standyby it apears me the message "locked by android device manager" and I have to enter the password again.  Do you know how to remove this message?

I'm setting up a server for backing up my desktop box remotely. I want to prevent remote password access to the server, permitting only users with private keys (AKA my desktop box) to access it. How can I block remote password access while allowing physical password access to the server?

I have an Samsung Galaxy S3 Neo.  Bus 002 Device 042: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]   The keyboard &amp; language setting is português.  I today installed Android Device Manager and to test it's functionality I locked the phone with the password: "abcd" (4 letters were required).  After entering the password and confirming with the "OK" button of my keyboard, the phone showed me that the password is wrong. "Senha incorreta".  I reset the password after some tries to "123456" and the phone reloaded the lock screen. Again the password showed up to be wrong. I also tried the alphabetic password: "abcdefg" - same error.  I changed the language of my Google account from German to Portuguese and reset the password to "123456" again and I tried to really reboot my phone and unlock the SIM card again. But anyways I can not get through my lock of the Android Device Manager.  I tried to enter the password 35 times wrong with hope to get a chance to authenticate with my Google Account login.  I also tried to connect the phone with adb but it does not show up in this state with:  adb devices   So what can I do to get access to my phone again?

On many microcontrollers or other devices without JTAG/SWD functionality, there is a reset pin which when low unconditionally and asynchronously forces everything into a known state.  On devices with JTAG or SWD functionality, however, things seem to be more complicated since it's possible to perform some JTAG/SWD functions while the reset pin is asserted.  I have some Freescale KL15Z-based boards which include the SWD pins on a connector with the reset line and some other diagnostic I/O pins.  Occasionally when connecting or disconnecting a cable, the parts seem to get into a weird state such that even reset won't kick them out.  I'm wondering if some stray pulses on the SWD pins might be putting the device into an "ignore the reset pin" state.  I have found that when using the debugger, I seem to have frequent difficulties getting the devices to reset reliably; I don't know if the issues may be related.  What is the relationship between the reset pin and the SWD functionality?  Conceptually it would seem most helpful to have a design where any falling edge on reset would be guaranteed to actually reset everything, and SWD communications which were supposed to happen before user code startup could be performed with reset held low, but I don't think that's how the Freescale KL15Z chips actually work.  What's the best way to solve such reset-related problems with the Freescale or similar parts?

I'm trying to come up with a WiFi solution for an industrial building, 100 ft long by 50 ft wide, with 3 main areas. See image below  Concrete walls separate the rooms, and the one long room is a semi-corrosive wash-down area. Staff use mobile devices that require a strong, uninterrupted WiFi connection, and they are often moving throughout the building while using the devices. I don't want repeaters or extenders or any other mechanism that would result in multiple SSID or channel connections for a tablet to contend with (dropouts for reconnection, or failure to switch to a stronger signal, etc). I just want to use one access point, but just with better coverage. Instead of trying to buy the most powerful access point on the planet, using brute force to blast through those walls, I was thinking of using extension antennas. So I'd take a consumer-grade access point with 3 standard antennas, remove 2 of them and replace with coax extension cable (green in the image) and keep 1 original antenna (blue). Especially for the wash-down room, I was envisioning drilling a hole in the concrete wall and slipping the antenna cable through, so in the end, only an antenna would be exposed to the corrosive environment, and still provide good signal strength to staff in that room. My ultimate question is: will this work? Is there something I'm not aware of, like perhaps that access points with multiple antennas aren't designed to work with their antennas separated by 10-20 ft? Thanks

I know the definition of Airplane mode is all communications and radio signals are blocked. But is it possible to turn off the "calling/receiving" part of the phone so your phone is not connecting to a cell tower and only allow Wifi? I've looked into a couple of apps in Google Play but they're either not working or out of date with newer versions of Android.   I know there is strong opinions on both sides of the issue but I'm worried about radiation from my phone since i use it a lot in bed and I hold the phone close to my head and face. At night I'm not worried about receiving calls, so I just want to turn off the phone part and  use WiFi. Is there a way? Or am i just crazy and paranoid?

Recently a user unplugged their company PC from the network and used USB tethering with their Android phone to bypass the company network entirely and access the internet. I don't think I need to explain why this is bad. What would be the best way, from a zero-cost (i.e. open source, using scripting and group policy, etc.) and technical standpoint (i.e. HR has already been notified, I don't think that this is a symptom of some sort of deeper underlying corporate culture problem, etc.), to detect and/or prevent something like this from happening again? It would be nice to have a system-wide solution (e.g. by using group policy), but if that is not possible then doing something specific to this person's PC could also be an answer.  A few details: The PC is Windows 7 joined to an Active Directory domain, the user has ordinary user privileges (not administrator), there is no wireless capabilities on the PC, disabling USB ports is not an option  NOTE: Thank you for the great comments. I added some additional details.  I think that there are a lot of reasons why one would want to disallow tethering, but for my particular environment I can think of the following: (1) Anti-virus updates. We have a local anti-virus server that delivers updates to network connected computers. If you are not connected to the network you cannot receive the updates.  (2) Software Updates. We have a WSUS server and review each update to approve/disallow. We also deliver updates to other commonly used software programs such as Adobe Reader and Flash via group policy. Computers cannot receive updates if they are not connected to the local network (updating from external update servers is not permitted). (3) Internet filtering. We filter out malicious and, uh, naughty(?) sites. By using a tether you can bypass the filter and access these sites and possibly compromise the security of your computer.  More background information: HR was notified already. The person in question is a high level person so it is a little bit tricky. "Making an example" of this employee although tempting would not be a good idea. Our filtering is not severe, I'm guessing that the person may have been looking at naughty sites although there is no direct evidence (cache was cleared). He says he was just charging his his phone, but the PC was unplugged from the local network. I'm not looking to get this person in trouble, just possibly prevent something similar from happening again.

I just installed Ubuntu 14.04 Server and cannot get wifi configured correctly to work with WPA2 personal and could use some help.    There was a simple wizard during install where I selected my SSID from a list and entered my passphrase and that worked great.  Now that the install is done I am having trouble configuring wifi.  My Access Point is setup to WPA2 Personal TKIP or AES. Any advice would be greatly appreciated.  I have been messing around with WPA supplicant ant my /etc/network/interfaces file with no luck.  Thanks

I am trying to install the self-signed certificate for my web server in Android 4.3. I have the .crt file in the root of the SD card (which is actually emulated as I have no SD card in the slot).  To install the certificate I go to Setting -> General -> Security -> Credential Storage -> Install from device storage.  I get a dialog box showing the name of the certificate (the filename  minus the .crt extension) which I can modify (but don't), a "used for" pull down with "VPN and apps" selected and text at the bottom of the dialog which informs "Package contains: one user certificate". Everything looks okay, so I click "Ok". The dialog goes away and a toast message pops up with "[name] installed".  However if I immediately go to "Trusted credentials and select "User" there is nothing there! The new cert is also not under "System" but I would not expect it there.  If I go to a browser after this and try going to my web site, I still get the warning that the site's certificate is not trusted. I have also tried rebooting, but it doesn't make a difference.  What am I doing wrong? The complete lack of error messages isn't helpful.  Is it possible my certificate is in the wrong format? I have tried using the .crt file in the server's ssl directory and I have tried converting it to DER format.   Update: I read somewhere that Android requires certificates to be in p12 format, so I converted the Apache2 certificate to p12 using the following command:  openssl pkcs12 -export -inkey server.key -in server.crt -out ~/server.p12   I then repeated the above steps, got the same success message, and then proceeded to still not see the certificate in the user credentials and I still get the untrusted certificate error from the mobile browser.

I work on a site that serves mobile phones and shares some file. When I publish my site in http everything works great.  But when I activate SSL and publish my site via HTTPS with my own certificate, Android doesn't download any file from my site.  I create my own SSL CA certificate via openSSL in my local  PC and not purchasing from standard seller like GoDaddy.  How do I install my CA certificate to Android?  Do I have to purchase SSL from a standard seller to solve this issue?  My android version is 4.4.4.
