Sometimes Google Android Jellybean 4.3 slow down for a few seconds after it starts up, and the icons/short cuts disappear for a few seconds on the home screen, and my tablet becomes unresponsive when loading apps, or trying to load apps after start up. I think it is caused by Apps which start up, and have performance problems where it slows down Android 4.3 after start up.
I think I fixed it by uninstalling Facebook, Facebook Messenger, and a few other third party apps. I now mostly use the web browser version of Facebook at M.Facebook.com which is good enough for sending a quick message, browsing the news feed, etc. But, I notice Facebook Apps used the most RAM according to Clean Master’s Task killer application. Twitter, Pinterest, and Tumblr also have mobile versions of their website, and there are sometimes third party app developers which make apps you can use to access different social networks, and services, but use less RAM, and CPU cycles than the official app from Facebook, Twitter, and Tumblr.
I also used Clean Master to see which apps start up during start up, and uninstalled the third party apps like Facebook which use a lot of RAM compared to other Apps like Hangouts, Gallery, Chrome, etc which also start up when I turn my Android tablet on. Running the Task Killer App in Clean Master once every few hours or when your device feels slow may help make Android feel more responsive by stopping background tasks.
Clean Master also has a cache cleaner, and junk file cleanup program which cleans up Android cache which may help with performance by making more free space available. Uninstalling big apps could help speed up your device. I read some Google Android devices with Android 4.1 had slow down problems when their internal memory got filled up. If your phone or tablet supports Apps to SD, you can move apps to an external MicroSD card to free up space on your internal memory card in your device which may free up space.
I read in blogs that Android 4.3 runs a command called TRIM which improves the performance of Android’s storage drive. TRIM is run when your device is charging, or idle with a full battery, so you can try leaving your device on while it charges to turn on TRIM to make your storage performance better after TRIM.
Removing Homescreen Widgets from your Homescreen could also improve Android’s speed while you use it since Widgets sometimes download information from the internet, run animation, and use up some RAM, and CPU cycles to use to display information on your Homescreen.
Using a picture as a wallpaper image rather than a live wallpaper may also make Android faster on slower devices. Turning off notification for apps which always send you notifications could also improve your performance. You can turn off notifications, sounds, vibrations, etc for Apps in the Apps settings section, or in the App section in the settings for Android where all the Apps are displayed in a list with a black blackground, and white text. Also, disabling automatic updates for Google Play can make your device faster since Android is not always automatically updating your apps when new app updates are available.
Using a different Launcher like Smart Launcher Free is probably one of the best and simplest ways to speed up your Android device during startup because it maybe lighter, use less RAM, and less CPU resources than the Launcher which came with your phone or tablet. I notice App icons on the desktop load a lot faster where there is no problems with Android shortcut icons disapearing after startup, and reappearing after a few seconds after startup. Now I can startup my tablet, and launch apps after Android finish booting up instead of waiting a few seconds after startup to launch apps. Apps also seem to load slightly faster with Smart Launcher.
I read Google Android Kitkat 4.4 will work faster even on slower phones and tablets with only 512MB or more RAM, and slower CPUs, so if your mobile device company release Android 4.4 update for your phone, or tablet, I recommend installing it. Most Google Nexus devices will be upgraded to Google Android Kitkat, so I recommend buying the Google LG Nexus 4-5 smartphones, and Asus Google Nexus 7- Samsung Nexus 10 2013 tablet, so when 4.4 is release, you won’t need to wait months for the updates, or no updates at all to 4.4 if your device maker decide not to support 4.4 on your phone or tablet by releasing an update.
If you need a tablet or phone which has very good performance, lots of free RAM, and CPU cycles to use for gaming, video editing, and multimedia, buying a new more powerful tablet like the Google Nexus 7 2013 Tablet with a Quad-core Snapdragon CPU, 2GB RAM, and 16GB of storage is a good choice, or using a cheaper phone or tablet like the ASUS MeMO Pad with VIA A4 1.0 GHz, 1GB of RAM, 16GB storageto run less resource heavy apps like Facebook, Facebook Messenger, e-mail, and social networking apps may also be a good idea, so Apps like Facebook and Facebook Messenger won’t slow down your faster tablet or phone when they are not installed on your tablet, or installed on a tablet which can easily handle the extra RAM and CPU usage from Facebook, and other apps.
