Why does your mobile phone hang?
Oops, my phone hung again. This is the third time in the last 3 days. I have to hard reboot my phone to set it right, letting go of any unsaved data. Why does my mobile phone stop responding at times?
You too might be facing the same problem with your beloved mobile. In the middle of something, it stops following your order. It starts behaving in an erratic manner. Here comes the million dollar question. Why does your mobile phone hang?
Let’s try to understand this in a very simple way.
Why is it a serious issue?
If your Android phone is crashing or is hanging very often, rest assured you will have a severe headache. Besides, mental trauma, you may face data loss, application crash, delay in your task execution, flickering videos and phone heating. Above all, your battery will drain out very fast if your phone hangs frequently. These are just some of the byproducts of the actual problem.
Reasons behind a freezing mobile
It sounds very simple, yet the phenomenon is a bit complicated. Why does your mobile phone hang? To know this, I will give you an overview of how a phone (An Android phone) works.
Processor or CPU is the brain of a mobile phone. It receives instructions from various units of the phone like an audio player, video player, camera, Apps etc. It then executes those commands by performing different calculations on them.
CPU performs billions of calculations per seconds. After the calculations, it sends the output to the screen or sound device or to a gaming app(for example).
One of the reasons for freezing up of a phone lies in its incapability to execute multiple commands issued to its CPU in a timely manner. If you are capable of doing only 10 jobs at a time and your supervisor assigns you 20 jobs, definitely you are going to fail. You will not be able to finish them off in the desired timeslot. As a consequence, the next lot of tasks would also be delayed and will be behind schedule. If this goes on for a long time, the queue of unfinished tasks will become quite long.
Not exactly the same, but a similar problem occurs with your cell phone. You start multiple apps simultaneously and your processor is not able to handle all the commands. It results in choking up of the processor and its cache and mobile freezes.
This is not the only reason behind a mobile phone crash. There are many more
Why does your mobile phone hang?
1. Insufficient space in phone memory may prevent apps to work properly
2. Too many apps on your phone may well create a bottleneck and crash your system
3. Virus/malware is a major reason behind the hanging and crashing of a mobile phone
4. Most of the phone models come preloaded with Bloatware which causes performance issue
5. Corrupt system files are also a possibility, although, not very likely
6. Apps which run continuously in the background may create a problem when you are running short of system resources
7. Last but not the least, malfunctioning hardware (less likely) may hang your mobile phone at times
It’s not a rocket science. There are a few easy steps (rather precautions) you can follow to save your mobile phone from being
Delete unwanted data
Maintain sufficient storage by deleting unwanted data – Always keep adequate free space in the phone memory. This is like oxygen for a mobile phone and also the most common cause of a mobile crash. I always use a third party App to keep on deleting temporary files from the phone. It will also help you in finding duplicate, bigger and unwanted WhatsApp videos. Here, I am specifically talking about audio and video files as they consume maximum space on your phone storage. Storing everything in your phone will fill the storage very quickly, and will hamper the phone performance.
Maintain enough free memory for Apps
Leave enough free memory for Android OS and Apps to run — Back to basics! All the apps and the operating system is copied to memory (RAM) before they run. If you are running low on memory, your programs may not get enough space to run properly, resulting in the system crash and hung phone.
Delete unnecessary Apps
Delete unwanted Apps to make free storage – Keep a tab on your storage. Keep only those Apps you really need. I feel tempted at times to keep the Apps I don’t need. If you will install the apps you don’t need tomorrow you have to uninstall the apps you really need. So, resist the temptation. Revisit your App store once a month to check and delete unwanted apps. Besides, freeing up the memory, it will also relieve the load on processor and hardware.
Keep your Apps updated
App developers update their apps regularly to make it free from any bug and security flaws. So, make it a regular practice to update your apps from Android
Install Apps in External Memory (SD Card)
To save space on internal phone memory you should always install your Apps in SD card instead of internal storage. This will ensure sufficient free space in your phone and will not be crammed with app data. Additionally, you can delete app cache or app data to make more storage. Every application stores some data in the phone; you can delete them without causing any harm to your app.
Move all your data to cloud
The best solution to keep your phone free from garbage data is to install a free cloud software (Google drive or Microsoft One drive or any other cloud backup software). These apps automatically upload your data to the cloud whenever there is any change. You can safely delete those files from your mobile phone. Now a day, Google drive comes pre-loaded with all the Android phones. You just need to configure it once and you are good to go.
However, there is one difficulty here; Google Drive provides just 15 GB of storage with your free account. If you don’t want to go for a paid account, make sure you configure only important folders for synchronization. Do not upload everything to Google drive; else your drive space will quickly fill up.
Install Antivirus Software
Virus and malware can make your mobile run slow, hang frequently or reboot automatically. They pose a the security risk to your personal data too. Never ever compromise when it comes to data privacy. When it comes to Antivirus, my personal favorite is AVG free edition. I have been using it since last 8 years and yet to face any virus infection (touch-wood).
Deactivate auto start apps
There are numerous Apps which start automatically when you start your mobile. Unknowingly, they eat into resources and also consume mobile data. Go to settings, check the application and deactivate them if you don’t want them to start automatically.
Reboot Your Mobile Phone once a month
Sound like a cliché however, you should never undermine the benefits of rebooting a system. This is true equally for a computer system as well as a cell phone. After running for a long time continuously, phones tend to accumulate garbage data and files. They fill up the memory and choke its bandwidth. There are operating system specific settings which will be reset only after a reboot. In many, cases you will find that the problem just disappeared after a reboot.
So, if you don’t have a habit to restart your phone, make sure to do it at least once a month.
Factory Reset – the final solution
Though this practice is not recommended, you have always an option to factory reset your phone. If everything else fails, you are left with only one option. Factory reset will resolve most of the existing performance problems except some serious hardware issues. In most cases, I experienced that my phone no longer hangs after a factory reset. But the downside, It will erase all your data so, back up your phone before doing this operation.
Hard reset your phone – Warning!!
If your mobile is already hung and not responding to any key press. You have no option but to hard reset it by pressing hardware keys. The key combination for hard reset varies from model to model. (A very extensive and detailed article – here ). You can find the key combination on the company website or user manual. However, hard resetting a phone too often may damage the phone.
Frequent freezing of phone is a symptom of a bigger problem. However, if your phone has some serious hardware issues (related to memory, ROM or CPU), you must contact the service center to get it repaired.
