5 Harmful Things to Avoid on your Android Smartphone

Mobile phones have gone from mere communication device to a whole a lot of things. Whether a safe house for your information and important documents or a physical statement of who you are, our phones deserves to be taken care of at all cost.

Android smartphones are generally durable in nature, they are designed to last for as long as possible but due to improper usage, they begin to lag in terms of overall performance. Below are five most harmful things you should avoid doing on your Android phone if you don’t want to kill it before you know it.

1. Installing apps from unknown sources

Google Play Store is the official app store for Android phones. For security purposes, Android phones are set to refuse the installation of apps that are not from Play Store.

Turning off this setting and installing applications you downloaded or that was copied to you can be very harmful to your device. Some of these apps may be infected with malware or out-rightly malicious. Before installing apps from unknown sources, make sure it is from a verified publisher.

2. Skipping System updates

System updates are very important and should be done as soon as you receive the notification on your device, same goes for your Android app updates. The update could be a severe security patch or a response to a new security threat.

From my experience with Oukitel phones and Infinix phones, you won’t normally get notified when there is an available OS update but there is a ‘System Update’ app that let you know if your system is up to date. It is your responsibility to always make sure your software is updated; you can as well set your device to accept updates automatically.

3. Always charging your phone to 100%

As crazy as it may sound, always charging your smartphone to 100% has been proven to have a negative impact on your battery’s lifespan. According to a research that was conducted by Ashley Carman for Circuit Breaker, a scientist confirmed that anytime your battery reaches a 100% charge, some certain reactions that degrade the electrolytes and depreciates the battery occurs.

The research also debunked the rumor that leaving your battery plugged in overnight kills the battery… no, what does is letting your battery reach a full charge. According to the scientist, you should disconnect your charger once your battery reaches a 90% charge and never let it go below 30%.

4. Rooting your Android device

Phone Rooting is a very common practice in the Android world, it removes the restriction on what apps you should install or use and gives you maximum access to Android OS customization.

This is not that bad but you should be very sure you know what you’re doing, also be aware of the cons of rooting your Android device. A rooted Android phone is much more vulnerable to malware as there are no more restrictions preventing them. You may also end up bricking your device in the process of rooting it, I have once been in this type of situation with my Infinix Zero 4 Android device.

5. Making use of Public Wi-Fi networks

Unlimited data plans and gradually fading away and we all know mobile data can be expensive most times. Wi-Fi networks are generally cheaper, so for this reason, most smartphone users always leave their phone’s Wi-Fi turned on so they can browse at cheaper or no cost.

Every bit of information you receive or send over a public Wi-Fi network is visible to anyone that knows how to go about getting it. Public Wi-Fi network is an easy route for hackers to make their way into your Android device, always be sure the Wi-Fi network you are connected to is secured with a password or you will end up losing very vital information to shady people.

Takeaway Tip: Always set a PIN or Password on your Android Phone

Re-entering your password or pin every time you want to access your device can be very stressful and sometimes annoying but it is the best way to keep your device and the information contained in it to yourself.

You can alternatively use a lock pattern and set the device to lock after a certain period of being idle, your device should always require a password, a swipe pattern or a PIN to grant access. In a case of the device being stolen or misplaced, your information won’t be appropriate.
