How To Block Apps From Accessing The Internet On Android

If you have a lot of apps on your smartphone, you will consume a lot of network resources. For example, playing PUBG in the background can slow down the Internet; Therefore, you may want to block its access to the Internet. You can block some apps from using mobile data, but there will still be no problem connecting to Wi-Fi and consuming resources. In this article, we will teach you how to block apps access to the Internet on Android so that you can solve the problem. So, when buying a phone, remember that you can block your apps from accessing the Internet on Android.
If you want to minimize internet usage for apps and not block them completely, there are some common practices you should consider. You can use the Data-Saver feature in Android 7.0 and above. To access this feature, you must go to Settings and select Wi-Fi Network from the Network & Internet section. Note that this section is displayed with a special icon on some phones.
The Data Saver menu has a switch in the off position, and when you turn it on, you will see a list of controllable apps allowed to access the Internet.
By activating the data saver, you can stop the automatic playback and download of videos and limit the download of unnecessary images. You can also turn off location access for all apps when they’re not used again for further restriction and reduce data usage in the background.
To completely block Wi-Fi and mobile internet access, you need to download and install a third-party app from the Google Play store; The app to prevent Android internet disconnection is known as NetGuard, and it is also used in non-rooted phones, and it can be considered as one of the best apps to block online access to apps. Note that this app is free of ads and other privacy issues.
For users traveling internationally, NetGuard offers excellent features like blocking system apps. It should be noted that the NetGuard app will work on Android version 5.1 and above. Once you enter the app, you will see NetGuard disabled, and to activate it, turn on the toggle switch; This feature is very similar to using a VPN.
You will see two colors for network icons, each of which indicates on and off; This mode and colors will be displayed prominently next to the apps. All you have to do is tap on the icons to disconnect and connect them to the Internet.
In some cases, especially for messengers such as Slack, the incoming message of the desired application is received by the Google Play service, and you must disable the Internet for both cases.
The download manager controls the app’s Internet access in other cases, such as Zoom and YouTube. Fortunately, NetGuard supports all system applications.
You can change the Wi-Fi and mobile data icons to green again to restart the apps’ internet access. Note that this app also performs additional actions, such as blocking ads and recording the exact time the phone connects to the Internet. Finally, set up a metered Wi-Fi connection on your Android phone if you have limited Wi-Fi bandwidth. It should be noted that preventing applications from accessing the Android Internet without rooting with the mentioned methods will be possible.

How To Calibrate The Battery On Android Phones

One of the things that may happen to your smartphone after a while of use is a decrease in the device’s accuracy in showing the battery’s actual capacity. Sometimes there is a problem with old products: even though the battery is not at zero percent, the smartphone turns off.
This happens when the battery is out of calibration and needs to reset. Next, we want to explain what battery calibration is. (What is the caliber of the phone?)
  • Samsung smartphones have a feature called Quick Reset. This feature allows you to calibrate the battery of your Samsung device easily. To calibrate your Samsung phone, do the following:
  • Use your smartphone until the battery charge reaches 5%.
  • From the call application, enter the code *#0228# and select the option to make a call if the code is not activated automatically.
  • A pop-up menu will appear. From the displayed menu, select the Quick Start option.
  • Now, wait for the device to turn off and turn it on again. Check whether the battery charge percentage is lower than the previous number.
  • Connect the smartphone to the charger and wait until it is 100% charged.
  • Turn off the device and turn it on again. Also, disconnect the charger from the device.
  • Go back to step 2 and do this two more times.
  • By now, you should have done Quick Start three times, and the battery charge should be 100%. Dial the code *#9900# from the call application.
  • From the menu that will pop up for you, select the batterystats.bin reset option.
  • Exit the menu and restart the smartphone.
There is also an Android battery calibration app, and you can use the Android battery calibration app to do this. You can also access the battery test code on smartphones of different Android brands. In the following, we have put a list for you that you can quickly access to test the health of the phone battery from various brands.
The method we will explain below can be done on all Android smartphones. Of course, in the rest of the article, we will explain what should be done to calibrate the products of other brands.
  • First, you need to drain the battery capacity. To do this, use the smartphone until the device turns off.
  • Turn on the device again and wait for it to turn off again.
  • Now, connect the smartphone to the charger and wait until the device is fully charged.
  • After the device is fully charged, disconnect the charger from the smartphone.
  • Turn on your smartphone. Check the battery charge level. If it does not reach 100%, connect the charger to the smartphone again, so it is fully charged. Now, wait until the charge reaches 100%.
  • Disconnect the charger and restart your device. Connect your smartphone to the charger again if the charge percentage is not 100%. Continue this process until the device shows 100% charge after restarting.
  • Use the phone until the charge reaches zero percent, and the device turns off.
  • Connect the device to the charger and fully charge it. Your smartphone will be calibrated by doing the mentioned method.
If there is a problem with the battery, sometimes the best way is to take the smartphone to experts and have the battery replaced. Of course, if you use a smartphone with a replaceable battery, you only need a new battery to fix the problem by just replacing the battery.
Of course, most smartphones that can be found in the market today use an integrated body, which does not allow the battery to be separated from the body. On the other hand, you should remember that sometimes calibrating the battery may not work, and your device may still have problems.
If you have recently installed a new app update for your smartphone and after that, your device’s battery has a problem, the problems may be due to app problems. In such a situation, it is better to wait until the release of a new update by the manufacturer to solve the problem.
Now that we know what phone calibration is, battery calibration should be done when you have doubts about the device’s performance in displaying the remaining charge percentage. If you don’t see any problem in the performance of the device in displaying the correct capacity of the battery, there is no need to calibrate it. The following are the correct times to calibrate the battery:
Even though your smartphone reports that there is a significant percentage of battery charge, it suddenly turns off.
Even though you use the smartphone for a long time, the percentage does not decrease or increase.
A lot of time has passed since your smartphone’s battery life, and you are suspicious about its performance.
Before we say the phone’s calibration, we must mention something. The smartphone should be able to monitor the battery and inform the user when the battery is fully charged or when its charge level is close to zero and needs to be recharged. However, the mentioned feature in the smartphone has a problem, the device cannot display the exact amount of charge in the battery.
Such an event may occur due to app problems or the increase in battery life, and its performance may be affected. In any case, there is a solution that increases the accuracy of displaying the battery capacity. Of course, you should remember that doing this will not improve battery performance. Such work helps the device to show the available battery capacity more accurately.

How To Improve Headphone Sound Quality On Android

Not satisfied with the volume of your hands-free voice? Many reasons can cause this issue, and there are many ways to solve this problem. This article discusses various methods, from the simplest to the more complicated ones, to increase the headphone Sound quality on Android phones.This technique is very effective when using Bluetooth headphones. You can also use this method to increase the volume of AirPods on Android. Below is a guide on how to make the headset sound louder when paired with an Android phone.
  • Go to your device’s system settings and click “About phone”.
  • Now, follow the steps System > About Phone > Build Number to enable Developer settings.
  • Tap on “Build Number” a few times until you are notified that Developer Options are enabled.
  • Open the Settings app again on your smartphone and look for Developer Options. Scroll down the list that appears and go to Networking.
  • Turn off the Disable absolute volume option.
This will make your phone distinguish between hands-free and phone volume. Now you can adjust the hands-free and phone volume separately. Note that the method of activating Developer Options can differ for each Android phone. For example, in Xiaomi phones, this feature is activated by tapping on the MIUI version. For more information, search for how to enable Developer Options on your phone.
This is the easiest yet most expensive way to get the most volume out of your smartphone. Buying quality in-ear or over-ear headphones can be an expensive move, but if you get the right product, it will be worth it. There are several options on the market that you can choose from. Many are designed to cancel noise outside the headphones to ensure the best audio experience.
This method will be costly, but it is a possible option for true music lovers. For some of these music lovers, more than just getting the best headphones are required. This group of users go to get a digital to analog audio converter. DACs handle Bluetooth and wired hands-free audio setups. Using this tool, in addition to a louder sound, you will get a higher quality output from your smartphone to be hands-free. Some DACs also offer wireless connectivity for Bluetooth hands-free.
If none of the above solves your problem, the problem may be simpler than you think. If you use wired hands-free to enjoy music, try cleaning the 3.5mm jack. The headphone jack (if present) is prone to attracting dust in the long run. You can use a clean ear to clean the hands-free input.
Similarly, in-ear headphones, especially the silicone series, require regular cleaning. Getting the handsfree dirty is normal and not a big deal, but cleaning it can be helpful. This is easy to do. To clean the dust that enters the hands-free sound channel, blow into it (remove the silicone series first.)
Also, always ensure that the 3.5mm metal end of the wired hands-free is clean and especially not wet before using them. Otherwise, your phone may be damaged.
Do you use Spotify, Deezer, Apple Music or Soundcloud services? By default, the streaming quality on these platforms is either set to auto or the lowest possible. Therefore, there is a possibility that the quality of playing music in these programs is low due to the low speed of the Internet.
This sound quality can also affect the volume. In the Spotify application, by going to the settings and in the Audio Quality section, then Streaming quality, select the music playback quality from automatic, low, medium, high and very high. Other streaming apps have similar settings, although the naming and path may differ.
Android phone owners can check the sound settings in the Sound and Vibration section of the settings. Find the Sound quality and effects section at the bottom of the settings list to check the sound quality. By entering it, you will have access to the equalizer settings of your Android phone. Here you can use the manufacturer’s default modes. These modes can be rock, hip-hop, jazz, classical, etc. Select the mode you want or enter the correct settings manually.
Note that the exact path of these settings and how to change them may differ depending on your Android phone manufacturer.
The Android operating system has plenty of excellent and high-quality music players. By changing your music player, you may notice an increase in the volume of your Samsung or other brands of hands-free. Especially if you use the main players of your phone, third-party players usually offer more features and better sound quality.
In the following, we will see that you will have access to the equalizer settings in the settings of Android phones. However, some players allow you to adjust the Bluetooth and wired hands-free sound through the equalizer settings. In addition to players, you can use advanced third-party applications to adjust your equalizer and sound. Note that only some equalizers will work on your ears. These programs increase the quality and sometimes the intensity of the phone’s sound.

10 Reasons Why Android Phones Overheat

Mobile phone overheating is one of the most common concerns of smartphone users, which sometimes worries them. Almost most smartphone users have experienced overheating at least once. Several factors play a role in the heating of the smartphone, which we have prepared a list of below. Stay with AndroidTechniques to know what are the reasons that android phones overheat.
Nowadays, the use of Internet users has increased significantly. Surfing the web, playing online games, etc., and using various social networks such as WhatsApp and Instagram require your phone to be connected to the Internet. Your continued use of the Internet increases the temperature of your smartphone. It is also necessary to know that you should expect more heat when you share your phone’s Internet with others through Hotspot.
Apps like WhatsApp, Instagram, Facebook and Twitter, which are constantly running in the background to keep their content up to date, have a significant impact on CPU and RAM processing, which also causes the phone to heat up.
You may have experienced slowness and speed drop as the temperature of your phone rises. This process may be due to the processor being locked to cool down your phone as a security precaution. Malware running in the background may be the reason for this lock; Therefore, we recommend you check your phone for malware.
Smartphone users often use screen protectors and frames to protect their devices from impact, but they ignore the fact that they prevent the heat of their phone from dissipating. Like other electronic devices, a mobile phone needs energy, and the use of this energy produces heat. Most smartphones dissipate the heat produced by the body and the holes they have, so using a frame and protective layers can make heat dissipation a little more complicated.
Most of the mobile battery charge is consumed by the display. The higher the display brightness, the higher the battery drain. Discharging the battery, on the one hand, and high screen consumption, on the other hand, cause the temperature of your phone to increase significantly.
100% charging of the mobile phone, in addition to shortening the battery life, also increases its temperature; Therefore, our advice to you is to avoid charging your phone 100% and charge it between 20 and 80%.
Using a fake and non-original cable and adapter is another reason that increases the temperature of your smartphone, in addition to reducing battery life and charging.
You should also remember that some chargers are designed for more powerful devices, which can damage the battery and cause it to overheat. We recommend you use the charger and cable suitable for your phone. You can read the guide to buying chargers and charging cables for more information.
Our smartphones are now full of information, from family photos and videos to work projects and chats. So, none of us like our smartphones to get damaged, and we must delete the data on them. In addition, the price of a smartphone is not such that we can replace our phone with a newer model in case of failure, which makes us take more care of our phone. One of the things that can cause severe damage to different parts of the phone, in the long run, is the issue of Android overheating. When the phone gets hot, in addition to reducing the hardware performance, the battery and other parts are damaged, and we should prevent the phone from getting hot as much as possible. What should we do now, so the Android phone does not heat up?
Generally, it is normal for Android and iPhone phones to heat up. We cannot expect that the phone will not heat up when it is connected to charging or playing heavy games but to improve this issue, we can take various measures, which we will discuss below why the phone gets hot while charging.
  • Do not expose the phone to direct sunlight. This causes the phone to heat up.
  • Turn off fast charging mode if you are not in a hurry to charge your phone. In Samsung phones, you can easily disable fast charging by turning off an option and charging your Galaxy normally. Fast charging causes a high temperature and hurts battery charging in the long run. To turn off fast charging, go to Settings>battery and device care>battery>more battery settings and turn off Fast charging. Whenever you need to charge the phone quickly, you can enable this option again (it is impossible to turn this option off/on while connecting the charger to the phone.
  • When charging the phone or playing games, remove the case from the phone so that the heat can be easily transferred from the inside to the outside. The presence of the frame plays the role of insulation and prevents heat from escaping.
  • Do not operate the phone while charging. In addition to heating the battery, this causes additional pressure on the chip and battery when charging. If you have to do something with the phone, take it out of charge and work with it. In general, smartphone batteries are currently in such a way that there is no need to charge them fully, and you can charge your phone with a 30% charge when needed. Therefore, if you are working with the phone while it is charging, disconnect it first.
  • This overheating may be due to the constant opening of applications in the background. To solve this problem, you should put your apps in the following categories to save battery power and prevent all apps from accessing the background. Go to Settings>battery and device care>battery>more battery settings. In this section, be sure to activate the Adaptive battery option. By turning on this option, the phone will automatically limit access to less-used programs and optimize the battery charge in the best possible way, according to your use of the phone.
  • Follow the path above and go to Background usage limits in the settings of the battery section. In this section, activate the Put unused apps to sleep option so that less used apps go to sleep mode and then put your apps in one of the three categories below. The first category is Sleeping apps. Go into this section and add apps to this section (via + on the top right) that you use less often but still want to receive notifications from. These programs run in the background, but only partially. The next category is Deep sleeping apps. You should put your unused apps in this section. We all have apps on our phones that we don’t use much, and we want to use them once in a while, and it doesn’t matter if we don’t get notifications from them. By adding programs to this section, their access to the background will be limited, significantly affecting the optimal use of charging. The last category is Never sleeping apps, in which we do not recommend placing any program in this section; Because these programs will always work in the background. Only put applications in this section that are of double importance to you.
  • If you play a lot with your phone or do heavy work, after every 30 minutes, put your phone aside for 5 minutes so that the phone can remove the generated heat and its performance will not suffer. If you continue to play with the phone while it is very hot, it may cause severe damage to the screen or chip or even the battery, so be sure to take the issue of overheating seriously when doing heavy work with the phone.
