Checking Available RAM and CPU utilization on your Samsung Galaxy S8 is very helpful if you are thinking about removing more Apps.

Looking at which Apps drain your RAM, CPU time, and battery will help you decide which of them should be removed from your phone.

To do this, just follow the simple steps below:

  1. Go to your phone settings. You can do this by swiping down the home screen to reveal the notification bar. From there, tap on the gear icon to open Settings.
  2. Look for Device Maintenance → Memory
  3. Alternately, you can also tap on “Data Usage,” then scroll down to see which apps are taking up CPU power.
  4. You may also look for “Smart Manager.” You will see the status of your RAM and Storage in this area. If you tap RAM, you will see a list of apps that are taking up much of your RAM.
  5. For Huawei users, you can look for “Storage” under Settings.

All methods from 2 to 4 can be accessed on the Phone Settings alone. There are certain variations, depending on your phone or unit.

This section should also show what is taking up valuable CPU time. Useful if you think some Apps are draining your battery.

If you want to install Apps outside of the Play Store (called sideloading), then go to Settings – Lock screen and security and select Unknown sources.

This setting will allow you to download Apps onto your device that would normally be blocked in the Play store.

Note: use at your own risk.

To delete or remove home screen widgets, simply press and hold. Then drag the widget to the top-right corner of the screen and into the Trash icon.

To use your phone as a WiFi hotspot, tether it via USB or via Bluetooth, then go to Settings – Connections – Mobile hotspot and tethering.

You can then choose from three options:

1) USB – connect your phone via a USB cable. The phone should automatically configure the correct settings.

2) Mobile/WiFi Hotspot – To turn your phone into a WiFi hotspot, press Configure WiFi hotspot. You will then be asked to enter a Network SSID (this is your own name for the WiFi hotspot). Then choose Security and lastly, choose a password (this is password for your WiFi hotspot which you will enter on your computer).

3) Bluetooth – With this option, you will need to pair a Bluetooth device with your phone. On the other device, ensure you search for Bluetooth devices and your phone should show up.

If you are abroad and don’t want to pay high data roaming charges, then you can save Google Maps for offline viewing later. Here are two ways to do this:

The first method will depend whether your phone supports it.

First, open Google Maps and navigate to a section of the map that you want available offline.

Then on the search bar at the top, press the Hamburger / Menu icon and select Offline maps.

Next, choose Select your own map.

Then zoom and pan around the required map area. The size of the offline map will be shown beneath the map area. When done, press the Download button.

Alternatively, open Google Maps and zoom down to street level. Then scroll around area you’ll be travelling too. If you’re visiting a city for example, do this at street level and cover as much area as you think you’ve be visiting. If you’re travelling outside a city, then street level view might be too detailed, so zoom out and just cover the main roads, towns etc.

This will load all the segments into your phone’s cache. Then when have arrived at your destination and you have data turned off, you should see the areas you’ve stored on the phone’s memory.

Note: this won’t give you your GPS location because that normally needs a data connection to pinpoint your position.

If you see an insufficient storage available error, or find that you’re running low on your phone memory (not to be confused with your SD Card memory), then there are a number of ways to fix this.

This error can be very frustrating as it often means you cannot install new Apps, and some Apps may not even function properly because of this. We hope this guide is as comprehensive as possible, but if you find other methods, then please suggest them in the comments below.

The first step is to determine exactly what is eating up your phone’s storage memory. To do this pull down your notifications menu and select Settings and find Storage. It may take a while to calculate so be patient. From here you can see whether it is your Applications, Pictures, Audio or otherwise, that is causing the problem. Obviously, if it is photos or music, then the first step is to remove some of these (ensuring you do actually want them deleted of course!).

If it is your Apps taking up space, then you have a few options, as follows:

Uninstall Apps – Go to Settings – Applications – Application Manager and swipe to the ALL tab at the top. Then look at the bottom of the screen which shows how much free space you have. Often you will have very little Free memory, which is the cause of the error. From here, press your Menu button and select Sort by size. This will show you which Apps take up the most space and which will make the most impact by removing. Obviously don’t delete things like Gallery (which will remove your photos!), Internet (which is your browser), key Google Apps and so on. However if you have Apps you don’t use anymore, then uninstall them to free up space.

Clear App Cache (with an App) – For this method, you will need to download an App called Clear App Cache. However, this will only work if you can uninstalled enough Apps to free up enough space to install the App itself. Once installed however you can quickly clear the cache of all of your Apps, which should free up some space.

Clear App Cache (manually) – Apps such as Gallery, can sometimes generate a large cache (image thumbnails in this case) which can be cleared to free up memory. First, go to Settings – Applications – Application Manager. Then swipe from right to left until you’re on the ALL screen. Then press the Menu key and Sort by size. Then choose the largest App by pressing on it. Then select Clear Cache. Do this until you’ve cleared as much space as you can.

Dump your log files – This will only work on some devices, however it doesn’t cause any data loss. It simply cleans up your App log files. Go to your phone dialler App and press: *#9900# Then Select delete dumpstate/ logcat and hit OK.

Move Apps to SD Card (if you have one) – Settings – Applications – Application Manager. Flick from right to left until you get to SD Card. Then simply tick which Apps you’d like to move from Phone memory to SD Card memory.

Clear Browser Thumbnails – This one seems to be a bug in some versions of Android and/or some phones, but is a very quick and effective fix. Simply open your stock Android Brower, which is usually found by opening the Internet App. Then at the top right check if you have multiple tabs open. If you do, then swipe them off the screen one by one until you have none left. This can clear up hundreds of cached thumbnails which never clear unless this process is carried out. It has been known to clear several gigabytes of space for users that don’t close their tabs often.

Check folder/file sizes – The last method is great and involves installing an App called DiskUsage from the Play store. Once you install this it will show you which folders are the largest. You can then drill down to find out exactly what is consuming your precious space before deciding to remove the files or folders. You can also integrate the App with File Explorer Apps to easily manage your files. When it comes to removing files and folders it’s sometimes easier to do that by plugging your device into a PC and browsing the folders that way.

There are a number of ways to speed up your phone. The following list are tried and trusted techniques:

Firstly, uninstall apps that you don’t use. Over time your device can get cluttered as some Apps are designed to always run in the background. If you don’t use an App very often, then uninstall it to free up memory and CPU resource.

Use Static wallpapers instead of Live ones. Live wallpapers often consume processing power and memory. Unless you really need them, uninstall them.

Use home screen widgets sparingly. These often slow down the phone and use up memory and CPU resources. If you don’t really need the widget, then uninstall it.

Install a great App called DU Speed Booster and DU Battery Booster. These Apps are prefect to run when your phone starts to slow down, you’re running out of memory or you want your battery to last for a few more minutes or hours.

Kill tasks occasionally – Some Apps will run in the background indefinitely unless you kill them. Most of them won’t cause a problem, but it pays to check your running tasks from time to time. Hold down your Home key and check the Task Manager.

No one likes nuisance phone calls, so here’s how to deal with these on your phone.

The first option is to block all anonymous calls, although this may block some calls from people or companies that you do want to allow, so use this carefully.

To enable this, go to your Dial App press the settings icon in the top right. Then choose Settings.

Then choose Block numbers and then Block unknown callers.

Secondly, if you’d like to block calls on a case-by-case basis, then follow these instructions:

First, wait until you’ve been called by a nuisance number. You can either answer and verify who they are, or when the phone is ringing, do a quick Google search for the number (ideally on a PC, otherwise you may need to switch between apps on your phone).

Often the number will come up on Page 1 of Google and be reported as a nuisance call number. You can often tell pretty quickly because the number will have many negative review.

Then once the phone has stopped ringing, go to your Dial App and then select Log to find the number on your recent call list.

Find the number that called you and press on it. Then in the top right, select More and select Block/unblock number.

To manage this list, then go back to the first screen of your Dial App and press the settings icon in the top right. Then choose Settings.

Then select Block numbers. From here you can see which ones to block or unblock.

From now on you will see that you received a missed call, however the phone will not ring and you won’t be bothered by the caller.

If you want to access certain features of your device that are only available to developers, then you want the Developer options setting.

On most devices, this feature is hidden so you will need to pull down your notifications screen go into Settings. Then scroll down to About device or About phone.

Then select Software information and you should see Build Number.

Press on this option a total of seven times. You should get a message at the fourth press. On the seventh, you’ll get another message saying that Developer Options are unlocked.
