6 ways to unlock your tablet if you forgot your pattern

How to unlock the tablet if you forgot the pattern for entering the system?

A graphic key is a very reliable data protection on a tablet computer, but sometimes the gadget owner himself becomes its hostage.

For example, if he forgets his key.

It is also not uncommon for a device to fall into the hands of a child, which creates a graphic password by accidental actions, saves and, of course, does not remember it.

And it becomes impossible to log in.

To everyone’s joy, this situation is not fatal. In most cases, the tablet can be unlocked by resetting the pattern.

• Via SMS
• Through a phone call
• Using a Google account
• Through the Recovery menu
• Through data reset
• By flashing method

It happens that you have to sacrifice information stored in the device’s memory, but more often you can get by with “less blood”.

Here are six ways to unlock your Android tablet if you can’t remember your pattern password.

Through a phone call

How to unlock your tablet with a call if you forgot your pattern?

• Make a call to a locked device from another phone.
• After receiving a call on Android 2.2, it becomes possible to enter the “Settings” application. “Protection”. “Lock screen” and change the pattern.

Another option is to call from the locked tablet itself.

After dialing the number and pressing the call button, the desktop literally opens for a moment.

If at this time you have time to click on the application icon (any), it will be possible to enter the “Settings” and reset the key.

Via SMS

This option is one of the quick and easy ones, but it will only help those who foresaw a situation with an accidental blocking of the gadget and installed the SMS Bypass application on it in advance, and also received superuser rights (root).

Naturally, the device must be equipped with a SIM card reader.

So, how to unlock an Android tablet using SMS Bypass if you forgot your pattern?

• Install the app from Google Play. It’s NOT free, but it only costs 1.99. To install, you need access to the global network and a Google account.
• Give the app full access to the device.
• Set in SMS Bypass the secret code to reset the pattern (its default value is 1234). To prevent outsiders from doing this, it is advisable to come up with a more complex code.
• When blocking, send an SMS with the text “secret_code reset” from another phone to the SIM card number of your tablet. For example, “1234 reset”. The pattern will be reset.

Samsung

The most interesting in the context of the topic under consideration are the Galaxy Note smartphones and Samsung tablets that support the pressure sensitive S-Pen and are equipped with a Wacom digitizer. We can take advantage of all these advantages and transform a mobile device into an almost complete graphic tablet:

• Download the VirtualTablet Lite (S-Pen) application on your phone or tablet, available for free on the Play Store: https://play.Google.com/store/apps/details?Id=com.Sunnysidesoft.Virtualtablet.Lite (there is also a paid one version without ads).
• Download and install the VirtualTablet Server program on your computer, available at http://www.Sunnysidesoft.com/virtualtablet/download/
• Start VirtualTablet Server on the computer after installation. If you plan to connect via Bluetooth, then when prompted by the program, allow the search, in my example I connect via Wi-Fi (the computer and smartphone must be connected to the same network). Wait until the Status field in the program reads Ready. Please note that it must not be blocked by a firewall.
• After starting the server, launch the VirtualTablet application on your phone or tablet, and then select the connection type: Wi-Fi, Bluetooth or USB (for the last point, you will need to enable USB debugging on Android).
• When using a Wi-Fi connection, if both devices are connected to the same network, you will see a list of servers in the application (or you can manually enter the IP address). Select the required server and click the “Connect” button in the application.

Done, the virtual graphics tablet on your mobile device is launched and can be used in graphics programs.

For example, paint in Photoshop using all the additional features of the brushes, and if Windows Ink Workspace functions become available on your computer (the icon usually appears automatically in the notification area), you can also conveniently use the free Microsoft Fresh Paint application (available in the Windows 10 store).

If necessary, you can change the pressure and travel sensitivity of the pen in VirtualTablet Server on your computer. Also, pay attention to the following point: if your computer uses more than one monitor, the graphics tablet will only work for the monitor number 1 in Windows.

How to use Android as a graphics tablet for your computer

Among other interesting options for using an Android phone or tablet, one can single out the use of a mobile device as a graphics tablet for drawing on a computer, this will be discussed in this material. See Also: Unusual Ways to Use Android.

This feature is most interesting for Samsung Galaxy Note phones and other devices that support a pressure-sensitive pen. But, if you wish, you can take advantage of such opportunities on second Android devices: the only thing is that the drawing accuracy on a regular touch screen will NOT be too good.

A pen-free Android graphics tablet

If your Android device does not support pen input, you can still use it to draw on your computer, but with your finger. Unfortunately, in this case, the accuracy will be insufficient, and the pen may “jump”, which is due to the way the capacitive touch screens work.

This can be done using the VirtualTablet application already described above, but you will need to go to the application settings on the phone and in the “Input Mode” item will install “Finger Touch / Capacitive stylus”.

I recommend using this particular application, but there are other SIMilar utilities in the Play Store:

• Graphics Tablet. supports the same capabilities as VirtualTablet (pen and finger input, pressure) and also requires a driver to be installed on the computer. Connection only via Wi-Fi. But I couldn’t find the driver, but there is information about it on the Official page.
• Wi-Fi Drawing Tablet. no pen or pressure support, a kind of mouse emulator using your phone or tablet. The link to the server application for the computer is in the description of the application in the Play Store.
• Tablet Stylus. paid, not tested, but the software on the Official page is very SIMilar to the previous version, except that USB connection is supported. The link to the server application is at the end of the application description in the Play Store.

How to connect a tablet to a PC as a monitor?

Each owner of a tablet computer sooner or later thinks about how to combine his gadget with a stationary PC. For example, can you use a tablet as a monitor to connect to the system unit? The advantages are obvious: a compact and high-tech display can give a head start to profile monitor manufacturers, and, moreover, will save a considerable amount.

It is possible to use a tablet as a monitor. The easiest way is to connect it to the card located in the system unit via a cable with HDMI. mini HDMI connectors. Naturally, if this function is supported and there are corresponding inputs and outputs. HDMI. cable transfers any digital data, be it a photo. Audio files or something else. However, not all so SIMple. The HDMI connector on your tablet is a transmitter. And only the transmitter. SIMply put, it is capable of transmitting data to another source, but receiving information from it. Not anymore.

Attempts to transform an android tablet into a full-fledged monitor have been made more than once. Alas, today it is impossible for an ordinary user to fully implement this idea. Developers are NOT in a hurry to make life easier for buyers. Until manufacturers make HDMI output universal, it remains to be content with only a fraction of its capabilities. That is, to use the gadget only as a transmitter of information. Unless there is an enthusiast who will undertake to convert HDMI into a tablet. an input so that it can not only transmit, but also perceive signals directly from the card.
As of fall 2014, this continues to be a pipe dream.

An advanced computer user can try to solve the problem at the program level. Applications, developed just in this case, will reduce the time of “Shaman dances” to the required minimum. But before starting this procedure, you need to answer yourself a few questions. The main one is how often and under what circumstances I will use a tablet instead of a monitor.?

The fact is that you can use your tablet as a monitor in completely different ways:
1. Emergency situation when there is no alternative and is NOT foreseen;
2. The display of the tablet is used as an additional monitor if the main one is present. The information that is displayed on the main screen is duplicated on it;
3. The display of the tablet complements the main monitor and works in tandem with it.

Each option requires an appropriate approach and has different requirements for the owner in terms of technical literacy.

How to connect a tablet as a monitor

For installation, you need a cable with a USB-connector (to connect directly) or a contact via a wireless network (connect via Wi-Fi). Corresponding programs are also required. You can download them for free on the Internet.

Step-by-step instruction:
1. We are looking at the office. Site and Install the iDisplay program on your computer. The version of the program must be selected in accordance with your operating system. It’s free.
2. Find the iDisplay tablet app on Google Play. Here they are already asking for 5 for the application. We pay money or use internet search and download the application for free. Install on a tablet;
3. Restart your computer after installation;
4. Open iDisplay on your computer and SIMultaneously launch it on your tablet;
5. Further steps differ depending on the connection method. If the connection is via a USB cable, click “USB Connection”. If connected via a Wi-Fi network, the program will ask you to add a server. Press the plus key several times;

6. If everything is done correctly, the program will invite your data. Specifically, IP addresses, port and username. The port number can be found by moving the mouse to the iDisplay. IP should be viewed on the network. Choose a username to taste. The requirements here are NOT regulated;

7. Select “Add and Connect”.

If the previous manipulations were done successfully, the message “iDisplay autorization“. The window that opens will offer you to choose one of three options for further actions. For those who are not at ease with English, here is the translation: first.” reject tablet connection “, second.” connect once “, third.” Connect automatically every time you enter request from the tablet. ”We recommend choosing option number three (in English”.Always allow“).

Further customization

After you managed to “make friends” a computer with a new monitor, you need to choose in what capacity it will be used most often. Let’s remind: it can be the main monitor (when there is no other one), duplicate or additional (“expand the screen” function). Standard setting. right click on the desktop.

In cases where the tablet is the only PC monitor, in the desktop settings, you need to click on “Show desktop only 2”. Next, they will right-click on the iDisplay shortcut, select the “Settings” line and click on “launch at Windows startup” so that a checkmark appears there.

After rebooting and turning off the standard monitor (if available), the desktop will be available on the tablet screen. To do this, you need to enter the iDisplay program from it, which will start in automatic mode.

The inconvenience of the proposed method of connecting a tablet as a second monitor may be this: if you need to connect a monitor instead of a faulty one, you will have to rely mostly on memory and intuition. It’s basically impossible to set up a program on a broken screen, so you have to find another working monitor somewhere for at least 10 minutes. Well, or take care of the compatibility settings in advance. Another disadvantage. When starting the system, it is necessary to manually start the connection with the PC each time.

In parallel with this, you can use all the advantages of a tablet computer. In particular, use touch data input and move around the apartment, regardless of the maximum wire length. A tablet with a large display and a good screen resolution will help you enjoy all the delights of a stand-alone monitor.

The creators of Android have provided an obvious option. an intricate figure that the user himself invented will be forgotten and he will lose access to his favorite gadget. Therefore, there are several ways to restore it when blocked. They differ in the degree of complexity and conditions. You must have a device with Internet access, a Google account, certain skills, etc. Let’s list what you can do if your Android phone is locked in order of increasing complexity of the actions performed:

• Unblocking with your Google account
• Reset all settings.
• By discharging the battery.
• Deleting a special file.
• Service Center Help.

There are many options, but it’s safe to say that the phone will be unlocked. Now in more detail about THESE methods, so that users can choose the best one for themselves or prepare in advance.

Unlocking your phone if you forgot your picture password by resetting all settings is a reliable, but rather painful way for the user. After all, sometimes very valuable information is lost. This can be avoided by knowing certain tricks.

The trick is as follows. You need to go to the Recovery menu. How to do this and how to navigate through it is described in the previous section. Then follow the path: Recovery. data. system. Find and delete gesture.Key in this folder. After restarting the phone, the lock will be unlocked.

Important: With this method, as with the previous one, you should be extremely careful. In case of incorrect execution, you can convert the smartphone into an ordinary brick.

How to unlock a phone locked with a graphic key by discharging the battery

Wait until the battery is discharged. To speed up the process, it is necessary to “torment” the battery so that the screen is constantly glowing. When the charge remains a few percent, the phone will notify about this and open a menu with power settings, that is, the lock will be removed. You need to quickly find the page with security settings in the menu and disable the lock. If there are sockets nearby, for example, on a hike, you can recharge the gadget using the Power bank.

And if there is no time to wait for the battery to discharge, because it can take several hours? Go to the next unlock method!

Note: This item is relevant for later versions of Android. In smartphones of 2018-2019, it is not always possible to go to the settings through the notification in a low battery. Most often, the system redirects the user to the page for entering a pattern or pin.

Unlocking via service center

In fact, this is the easiest way. You take the locked phone to a service center and they will carry it out NOT under warranty repair. This method has two drawbacks:

• You will spend quite a lot of time on this, especially if they do not immediately get down to work;
• It will cost you some money. Depends on the smartphone model and the appetite of the service center.

This review contains several unusual (at least for novice users) scenarios for using an Android device. Perhaps among them there will be something that will be useful to you.

What an Android device can do that you did NOT guess

I will start with the SIMplest and less “secret” options (which are known to many, but not everyone) and continue with the more specific use of phones and tablets.

Here is a list of what you can do with your Android, but most likely NOT:

• Watching TV on Android is something that many people use, and, at the same time, many are not aware of this possibility. And she can be very comfortable.
• Transferring images from Android to TV via Wi-Fi can come in handy sometimes. Most smartphones and almost all modern TVs with Wi-Fi support wireless transmission.
• Using the phone as a remote control for TV. fewer people already know about it. And such an opportunity exists for most modern TVs with Wi-Fi and other methods of connecting to the network. No IR receiver required: download the remote control application, connect it, start using it without looking for the original remote control.
• Android phone as a webcam for a computer
• Use Android as a remote control for a Windows, Mac OS or Linux computer or laptop

• Use Android as a graphics tablet for drawing on a computer or laptop, including using the pen and taking into account the pressure.
• Make an Android tablet a second monitor for a computer. this is NOT about the usual broadcasting of an image from the screen, namely, using it as a second monitor, which is visible in Windows, Mac OS or Linux with all possible parameters (for example, to display different content on two monitors).
• Control Android from your computer and vice versa. control your computer from Android. There are many tools for THESE purposes, with different capabilities: from SIMple file transfer to sending SMS and chatting in instant messengers by phone from a computer. Several options are described at the indicated links.
• Share Internet over Wi-Fi from your phone to laptops, tablets and other devices.
• Create a bootable USB flash drive for your computer directly on your phone.
• Use Android as a gamepad, mouse, or keyboard for your computer. for example, to play games or to control a PowerPoint presentation.
