If you own a mobile device, you may have experienced the issue of your device restarting on its own. This can be an occasional occurrence or it may happen frequently. In this article, we will explain the reasons why an Android tablet may reboot by itself and provide some tips on how to resolve this problem.
Mechanical breakdowns
Mobile technology is a delicate device that requires careful handling. Dropped and exposed to shocks, moisture, as well as extreme temperatures, can lead to the malfunction of internal components and ultimately result in the tablet rebooting itself. The best course of action in such cases is to visit a service center. It is not advisable to try and troubleshoot and fix the issue independently. At times, a faulty battery can be the culprit behind this behavior. It may become defective due to improper usage (tips for proper usage can be found here), or it may simply reach the end of its service life. If the battery is removable, one can consider purchasing a replacement battery. Otherwise, it is necessary to seek assistance from a service center.
Firmware
- official;
- customized;
- testing.
The official firmware is created by Google engineers or a specific tablet manufacturer. These updates are released periodically and aim to enhance performance, improve speed, and introduce new features. While most firmware updates are reliable and don’t cause any issues, occasionally they may contain errors that cause the tablet to reboot spontaneously. Fortunately, the solution is straightforward – reverting back to the factory version of the operating system and waiting for a more stable update from the manufacturer. Thankfully, manufacturers typically address these issues promptly.
Custom firmware is developed by third-party developers and has the capability to completely transform the user interface. It is important to note that these custom firmware options are not official, which means that installing them can be a risky endeavor. It is recommended to avoid installing new custom firmware and instead opt for one that has been thoroughly tested by many users and has received positive feedback.
The idea behind test firmware is self-explanatory. Third-party developers create firmware and invite interested individuals to test and evaluate its performance, convenience, and other attributes. These test firmware options are often available on websites dedicated to mobile devices. However, it is important to note that there is a higher risk of encountering errors and experiencing improper functionality with these test firmware options. If the device is not new and the potential consequences are not too severe, taking the risk may be acceptable. Otherwise, it is advisable to refrain from testing such firmware alternatives.
Viruses
While iOS is known for its low occurrence of viruses, Android lacks the same level of security. This is because of its open source code, which allows anyone to create a program and easily introduce a virus. If your tablet suddenly restarts on its own, it could be due to malicious software.
Here’s a helpful tip! In this situation, it’s advisable to install an antivirus program and perform a memory scan on your device. Kaspersky and Nod32 are excellent choices, although they require payment. However, they do offer a trial period which allows you to assess and clean your device. Once the antivirus has done its job, you can remove it. However, to prevent future issues, it’s recommended to keep it active.
To mitigate any unnecessary risks, it’s important to download and install verified applications from trustworthy sources, such as official stores like Google Play Market or the manufacturer’s dedicated stores (e.g., Samsung–Galaxy Apps, Xiaomi–Mi Store, and more). It’s essential to avoid installing software downloaded from third-party websites.
Applications
It is important to mention that at times the issues can originate from the programs themselves. In the event that the device started to exhibit irregular behavior following the installation of a new application, it is advisable to uninstall it and verify that the malfunctions have ceased. Once again, the problem lies in the open-source nature of the code – not all applications are developed by well-known developers. Numerous users create their own applications, and due to limited resources, they may not be able to conduct thorough debugging.
Another crucial element is that if the tablet is not from a well-known brand, even popular and relatively new applications may lead to malfunctions. Each manufacturer has its own Android firmware, making it impossible to tailor the program to all brands simultaneously. Typically, apps are tested on more widely recognized market leaders like Sony, Asus, Samsung, and Huawei. Once it becomes evident that the app is appealing to users, optimization for "no name" brands such as Prestigio and Irbis is initiated.
Instead of installing multiple different options, it is advisable to consult reviews and forums where experts can suggest the most suitable application for a specific task. This advice is particularly important when it comes to antivirus software. Having two antivirus applications installed can cause the device to malfunction and require a complete reset in order to revive it.
Memory
An issue of great concern with Android devices is their growing propensity to become bogged down with excessive memory usage. This is particularly noticeable in relation to messaging apps, which store photos, videos, and other data in multiple locations, often causing the situation where a photo deleted from the gallery still manages to linger in the device’s memory. It is highly recommended to use cleaning utilities on a regular basis, with CCleaner serving as an excellent example. This application ensures effective memory clean-up in even the most inaccessible areas, addressing the problem of the tablet slowing down and freezing, as well as the possibility of experiencing repeated reboots.
An issue with the drive is a defective memory card. If the device starts malfunctioning, it is advisable to temporarily remove the card and verify if the problem persists. In case it does, the old microSD should be formatted as the first troubleshooting step. If that doesn’t resolve the issue, then purchasing a new card is necessary.
Software failure can occur due to various reasons, such as user actions, installed programs, or external influences. When such failures happen, it can be noticed that the device automatically turns off and on, freezes during the booting process, or continuously restarts itself. Frequently, this situation occurs when the device is in the middle of a system update, and there is a disruption in the internet connection or the device shuts down because of a drained battery.
When faced with this situation, the sole solution to rectify the flaw entails performing a complete system rollback to restore the tablet to its original state, thereby erasing all data. In order to execute this process, the user must access the Recovery mode by pressing the physical buttons "power + home + volume" on the tablet. It is important to note that the specific combination of buttons may vary depending on the manufacturer, thus it is advisable to search for the appropriate sequence for the particular brand.
Battery discharge
There are instances where the tablet hasn’t been utilized for a period of time and the battery has completely discharged. In such situations, the device may not power on immediately and show no indications of activity. A similar scenario can occur even during normal usage. In these cases, it is advisable to keep the device connected to a power source for some time and observe its response. Typically, the gadget can revive from this dormant state after an hour or more of being plugged in.
