“Why my phone hangs so often?”, this is the lament of millions of people all around the world. Gone are the days of simple mobile phones like the famous Nokia 1100. Nowadays, mobile phones have become smartphones. These devices run on complex software (like Android, iOS, Windows, etc.) which require much higher hardware capacity.
Moreover, millions of apps are out there which vary in performance, quality, and resource utilization. Phone hanging refers to the state when a mobile phone will stop responding to the commands of the user. It is also called a phone crash and is characterized by screen freeze. When hung, no matter what you do, your phone will refuse to do anything.
In this article, you will learn about the reasons behind phone hang and possible solutions to this omnipresent problem. Occasional phone hanging should not be a cause of worry, but if it happens often, then you should try the tips given below.
1. Reduce the Number of Concurrent Apps to Stop Phone Hang
Each mobile phone comes has a limited amount of resources like memory (RAM) and processing power. If you overburden the phone beyond the capacity of these resources, the phone may hang. So, you should try and minimize the number of concurrently running apps. There are a number of apps that run in the background. You can free the clogged memory by stopping the apps that you don’t need at present.
To see the list of currently running apps, go to Settings > Apps > Running App.
2. Keep All the Apps Updated
Keep visiting the app stores like Google Play(if you have an Android phone) and iTunes App Store (if you have an iPhone). Mobile app developers keep on improving the performance of their apps. Therefore it is highly recommended that you regularly update all the apps as and when a better version is available. The latest versions of apps may be designed to use lesser memory and CPU power.
3. Shut Down Your Mobile Phone
Shutting down your phone every once in a while is a good idea because it will completely refresh the memory of the phone. When you will restart your phone, its memory will be free of all the unnecessary pieces of data that were lingering on and occupying the memory space.
4. Switch off and Remove Battery
This tip may not have any big effect at all in most cases. But it is also a good idea to remove battery and SIM cards every few months. Removing the battery and SIM will clean the dust from the electric touchpoints.
It is fine to remove mobile battery once in a while. It remove the dust at touch points. It may help in solving phone hang problem.
5. Install Apps in External Memory (SD Card)
Most of the mobile phone users install all sorts of apps on their phones. When installing the apps, they don’t pay much attention to where the app is going to be installed and what impact it can have on the performance of the phone. In most cases, by default, the apps get installed in the internal memory of the phone.
This leaves lesser space for running the apps and that in turn causes clogged memory. If your phone hangs, it is advisable to install apps in the external memory (i.e. SD Card) of the phone. Usually, the external memory is larger than the internal memory. And external memory can also be easily expanded if required (instead of 2 GB card, just insert an 8 GB card!). Therefore, in external memory, more apps can be easily installed without clogging the internal memory of the phone. This will save your phone from hanging.
For this you can set the default write disk. Go to Settings > Storage > Default write disk > Select SD Card. Please note that this setting is available in slightly different location in different mobile handsets. So, you may have to do a bit of look around.
6. Move Installed Apps from Internal to External Memory
You can always move the already installed apps from internal to external memory. As explained above, this will give more internal memory space for the smooth running of the apps. As a result your phone will not hang.
Setting for moving installed apps is usually available under Settings > Apps.

7. Delete Unnecessary Apps
You can also browse through the list of the apps installed on your phone. You might spot a few apps that you had installed once upon a time but you no longer require them. Uninstall such apps immediately. They stay idle on your phone and waste the all-important memory space.
8. Delete Unnecessary Data (like photos, videos, songs)
If you have stored images, videos, and songs in the internal memory; you’re really choking up the internal memory space and that could very well become the cause of your phone hanging all the time.
Go ahead, take a look at all the pictures, videos, and songs, and delete the ones that you no longer need. Alternatively, first, you can take a backup of this data on your computer and then delete it from your phone. Photos, videos, and audio take up most of the space the phone of an average smartphone user. And it is one of the common reasons why your phone hangs.
9. Identify Resource Hogging Apps
Some of the apps use much more memory than other apps. Game apps are among the top memory guzzling apps. You can check how much memory each of your apps is using. For this go to Settings > Apps (or Memory) > Running Apps. Here you will be able to see which app is using exactly how much memory.

If possible, you may try a lighter alternative of an app that is using a lot of memory. For example, if you use a news app and that app is eating up a lot of RAM; you may consider removing that app and install another news app from the app store.
10. Install Antivirus Software
Viruses are a menace. If your mobile phone is playing host to a virus, the virus can considerably slow down your mobile phone. Needless to say, your phone will hang often. So, obviously, you need an anti-virus. Although anti-virus software itself takes up a lot of memory it is better to have the virus removed.
11. Give External Memory Some Breathing Space
So far, I have been telling you about the importance of installing apps on external memory. But it should not mean that you choke up the external memory as well! Keep some space free in external memory also so that apps can easily store and read their relevant data. If external memory is also full to the brim, that can also become the cause of the phone hang.
12. Use Factory Reset Option
This should be your last resort. If nothing else works and phone stills hang, you can reset your mobile phone back to factory settings. Use of this option will remove everything from your mobile phone. You will lose everything that would be there in the internal memory.
And it will be gone forever. All the messages, contacts, apps, bookmarks, photos, videos, songs, ringtones… everything will be deleted. Essentially, this option will make your phone just the way it was when it was produced in the factory.
