Android Tips and Tricks - The Ultimate
After purchasing the first android Smartphone now it’s the time to master over it..., so here I’ll be talking about the ticks that can be played on your Android Smartphone...
a. Does your Smartphone lags nowadays, does some apps terminates unexpectedly..??? If yes, then you are facing the shortage of RAM. If you are having a Smartphone with less RAM ~512MB then you might have been quite familiar with these kinds of issues, the other reason is you might also have installed as many apps and these apps will have some process that are running background of the scene...!!! So the best way to tackle with these kinds of issue is to upgrade the RAM, which is practically expensive, but the smart way is to install some RAM Booster app and to run it periodically, in-order to clean up the cached datas, history, logs and temporary files. I personally suggest you to have Clean Master
b. Is the A/V player less effective...??? If yes, in case of Music player Android 4.0 provides an in built Equalizer, that supports 3D Effects when you plug-in the headset, so it’s better to Upgrade your Android version if you are lower than 4.0.4, the other option is to try Music Player for Android , Poweramp Music Player 
In case of Video I blindly suggest you to have Vplayer and this is really awesome.
c. Worried about the battery...??? Just Chill here I have DU Battery Saver with the rating of 4.7 in Google Playstore this is been the all time favorite of more than 25,000,000 users...! So you should really try this for once.
d. Do you use 2G, 3G... nG data plans a lot, then you must have a closer look on the data usage to know your exact data limitations and it’s also necessary to have a look on all the apps that are consuming your bandwidth, so I suggest you to use Onavo Count 
e. Now its the time to use your Android device as PC’s webcam, here I had already discussed about the usage of Smartphone cam as your Webcam ...
f. Have you forgotten to backup your phone or sim contacts...??? If not Reade this related to the back up of your contacts
So these are the basic apps that you must have in your Smartphone, there are so many other apps, ill be talking about them later in this post itself, well if you find something is been missing please feel free to share with me...
