Simplify your Android device experience with Pie Control: Pie Control (coolAce), Unique Controls, and Simple Control

Read the article on how to enable the mode on Android. As a rule, they are disabled by default. The Android operating system is represented by no interesting mode that allows you to make any changes to the platform. By default, most of them are hidden from the user's eyes, so that newcomers who do not understand the intricacies of the functioning of the system accidentally do not interfere with its operation. However, from time to time there are situations that require user intervention, which can only be done through these very modes. Today we decided to tell you about each of them: what are they for and how to use it.

How to enable safe mode on an Android phone

What is safe mode on Android: in fact, the mode in which the device appears in its original form. That is, only applications and services installed “from the factory” are launched.

As a rule, they resort to safe mode when it is not clear why there are related problems in the operation of the device, which may be due to installed applications. In fact, it helps to make sure that the culprit of the brakes is precisely the program, and not viruses, for example.

To enter safe mode on Android, you need to perform the most simple operations:
  1. hold down the power button until a window with the "Shutdown" and "Restart" buttons appears
  2. touch the “Shutdown” button and hold your finger (usually a couple of seconds) until we see a system message that requires confirmation of the transition to safe mode,
  3. confirm the action by clicking "OK",
  4. a smartphone or other Android device will reboot.

Confirmation that you have entered safe mode will be the corresponding inscription in the lower left corner. You can enjoy a smooth interface by uninstalling in a single application that are in doubt. To exit safe mode on Android, just reboot the device.

However, not every model with its own varieties of operating system works according to this instruction. For example:

  • HTC smartphones are put into safe mode by pressing the Menu button during system startup,
  • a number of Samsung smartphones are entered into the mode by holding down the Menu during power-up, when the logo appears on the screen,
  • in the case of CyanogenMod and some other third-party firmware, instead of holding your finger on the “Turn off” button, do the same with “Restart”.

If none of the methods worked, look for information about the security mode specifically for your model on the official website or thematic forums.

Activate developer mode on Android

What is: a special mode, closed by default from the user, which provides access to other useful functions and modes. As a rule, it is activated for any user who has mastered Android at least a little - it turns on in just a few clicks.

You should immediately warn that after activating the developer mode, you should not thoughtlessly include all additional functions. Yes, they are quite interesting and useful, but you should carefully study the descriptions for them.

Activating developer mode is very simple:
  1. go to the device settings
  2. we go to the very bottom of the window, where we select "About phone",
  3. we find the line “Build number” and tap on it many times (during the clicks a window will appear that will notify how many touches still need to be made),
  4. as a result, a message appears stating that you have become a developer, and an additional section with the corresponding name will appear in the settings (in some OS builds it is placed in advanced options).

Also note that in the case of third-party firmware, you must click not on the build number, but on the version of the shell. For example, owners of Xiaomi smartphones need to tap according to MIUI.

Developer mode can also be turned off. This is done using the last button located directly in the mode section. In some cases, the developer’s active mode can cause malfunctions in the functions.

What can you do in developer mode on Android? Here, it increasingly depends on the specific device, as well as its firmware. In some smartphones, the possibilities are minimal, in others there is a whole bunch of them.

Here are the most useful and interesting features:
  • Prohibition to turn off the screen. After activation, the display backlight will not turn off when the device is charging.
  • Visible clicks. In the active state, this function displays the point that will appear at the places where the screen touches. A very useful feature if you are recording any video tutorials on Android.
  • Visible touch. Instead of a dot, lines repeating your gestures will appear on the screen.
  • Onscreen buttons. Some models provide this function, despite the presence of full navigation buttons.
  • Animation Settings A very useful feature for owners of weak smartphones. In developer mode, you can set transition effects to a minimum to reduce resource consumption.
  • Various graphic settings. A number of smartphones allow the user to prioritize the use of hardware and software. You should not make changes without becoming familiar with the Web, which performs a specific switch.
  • Show processor load. A small window will appear on top of the interface, in which the system load will be displayed. It will be useful to gamers.

In general, you understand how many useful settings are hidden from our eyes. And we didn’t list everything, but with each new version of the OS, developers bring new ones.

Turn on debugging mode on Android

What is the debugging mode: in general, we can say that this is a useful tool that allows you to restore the smartphone after any malfunctions, get ROOT-rights, reflash the device and so on. Most often used by developers who test various tools and applications.

The debugging mode is useful to you whenever you go in to make any changes to the system directly from the computer. So, how does the mode turn on:

  1. If you are an old-school user who is still working with a device running Android 2.3, then:
    1. go to "Settings", where we need the "Applications" section,
    2. from the proposed list, select "Development",
    3. it remains only to put a checkmark in front of the first item "USB Debugging", simultaneously confirming the action.
  2. In a slightly different way, debugging mode is enabled on Android 4.0 and newer versions:
    1. first we get access to the developer mode, which we read about in the previous paragraph of the article,
    2. by going to the "For Developers" section, which appears in the settings, put the toggle switch next to "USB debugging mode" in the active state.

That's all. You can now connect your smartphone to a personal computer and do the necessary work.


Modern mobile devices are equipped with large screens, because of which it is difficult and sometimes impossible to control the gadget with one hand, which complicates their operation. Here you need some way out or a software solution. And here Pie Control can come to the rescue - the so-called dock panel, which opens from the edge of the screen and duplicates the classic Android OS keys.

Initially, this feature was presented in unofficial firmware Paranoid, CyanogenMod and only then exported as a separate application. It just so happened that Pie Control has no official version. All such programs were created by various developers, and this is good, because each of them brought a little of their own to the application.

So, further we prepare three top applications with Pie Control: Pie Control (coolAce), Unique Controls and Simple Control. Moreover, the first and last programs are made by one developer.

The following devices were used as test equipment:

  • Xiaomi Redmi Note 3 Pro smartphone (OC Android 7.1, Resurrection Remix 5.8.1, Snapdragon 650 processor 64 bit, 6 x 1800 MHz, Adreno 510 video processor, 2 GB RAM),
  • Jinga Basco M500 3G smartphone (OC Android 5.1, MediaTek MT6580 processor, 4 x 1300 MHz, Mali-400 MP2 video processor, 1 GB RAM),
  • Samsung Galaxy Tab 2 7.0 tablet (CM 13 based on OC Android 6.0.1, TI OMAP 4430 processor, 2 x 1200 MHz, PowerVR 540, 384 MHz video processor, 1 GB RAM).

Beginning of work

The first launch of Pie Control is accompanied by the initial setup of the application and its activation. And we immediately notice that not only the Russian language is absent here, but also the others, we will have to be content with English.

Already from the main application interface it is clear how and where the side menu will open. For each display orientation, we can configure the panel to open from any part of the screen, choosing between the sides of the screen, the bases and corners.

For the convenience of opening the Pie Control menu, we can configure its opening area. Again, for each part of the screen, for each corner, this area can differ markedly.

Please note that the size of the menu that opens depends on the display of a particular device and can be adjusted in the settings as we wish.

As an example, pay attention to the open menu Pie Control (coolAce).

If you notice, then the upper, lower and side menus contain two rows of function keys and additional information, the corner - three classic keys to control the system, as well as date, time, battery power and so on.

The display of all secondary information is regulated in the program settings. They are located in the same menu, only on the next two tabs.

The most pedantic users can even change the color of all panels and select other icons.

If we are talking about the parameters, then we will not move away from them to the side. Each Pie Control menu item can be customized in accordance with our preferences, and to be more precise, you can replace quick access to certain programs, functions, set their number and other nuances.

Owners of the Pie Control Premium application will be able to customize the third row of icons and functions, get folder support and the ability to display icons with useful functions in the corner menus. It will look especially interesting on tablets and other devices with a large screen, since the diagonal allows them to do so.

There are no dedicated settings in Pie Control, since they are combined with the settings of the menu, interface, and utility functions. And we all spoke about this earlier.


Pie Control (coolAce) will launch and will work on any current device with Android OS 4.1 and newer versions of the system.

For the entire time I used the utility, I did not encounter any problems, except for the lack of Russification and problems with the response in the range of the shortcut for opening the menu. True, the last problem is related to the screen of the mobile device and its response.

Application version 6.1.3
Distribution size 5.81 MB
Installed application size 16.02 MB
RAM consumption 40-60 MB

I have no problems launching the application, since for normal operation of the utility you need 40-60 MB of RAM and up to 20 MB of internal memory. Do not forget that the program is constantly in standby mode and consumes device resources. So, in the first test configuration, Pie Control consumes up to 3-4% of the total battery charge and 0.1% and 5% of the processor power, respectively.

Personally, in my opinion, Pie Control (coolAce) got closer to the original Pie Control and got around it! Yes, it was bypassed. Indeed, in this utility, in addition to the controls and a couple of elementary actions, it is possible to place application icons, assign various options and much more.

The utility is free, but if we want to add another row of icons, a folder, choose a different design style and something else, then for this you will need to purchase an additional package of options for $ 1.99.

App Rating: 9 on a ten point scale.
