I have one to blow your mind.
It is little yet powerful.
Want to know which app was used last time in your phone is pretty much easier by moving to recent app history or app switcher like this…
But what if someone has cleared it….don’t worry I’m with you.
Open your phone dialer and press *#*#4636#*#*
It will open up something like this.
Click on Usage Statistics.
Something like this will open up.
Move to Sort by – dropdown menu.
click on last time used.
All done now see the statistics with full details.
STUCK WITH YOUR MOBILE LOW WIFI SPEEDS

Want to remember something, moreover need a reminder every time someone messages you!!! Goto: 
Want to know someone’s Router Password, if you have access to their phone.?! Goto: 
Yeah, that’s right…. You are at the right place.

Here’s your soul saver.

Second open the setting panel by using the three dot panel, then select Advanced

Now select the option 5GHz. That’s all its done. You’re on your way for the free journey. Breathe easy and browse greasy.
REASON: Wifi in our phone uses 2 frequency bands, namely 2.4GHz and 5GHz.
2.4GHz band is like this busy street
5GHz is like the outer ring road in Bangalore and Hyderabad
DISCLAIMER: Your Access Point(Router) and phone must support two bands. Although, most of the latest phones and routers have both bands support.

 The trick lies in messaging yourself in WhatsApp. So that, every time someone messages you, you get reminded of the task.
Creating a WhatsApp group is all you need.
First, create a WhatsApp group with you and your roommate only (although you can include as many as you like).
Next delete your roommate, and only you remain in your group.
It looks similar to the one below
 All you need is the access to the person’s mobile and ES File Explorer.
Go to the following directory in his phone.. /data/misc/wifi. You will find a wpa_supplicant.conf file there just open it. All the passwords and networks are enlisted there.
Edit 1. Thanks Akash and Srikanth for reminding me.
PICTURE CREDITS: Myself and Google :p
Trick This can be also done by saving your whatsapp number as a contact. And initiating a chat from your contacts app.
Trick This trick requires root access, I had that in mind, but forgot to mention that.
A)Sometimes eventhough your router supports 5Ghz its not enabled by default, So you must explicitly go ahead and hard code(:p enable) that in your router settings. I presume you are aware of configuring Router settings, if not please inbox me.
B) Trick  can also be used in public wifi such as train stations, bus Stands. Here you can reap the phenomenon benefits of wifi and reach at a download speed upto 15Mbps. I personally reached at the download speed of 6Mbps at Vizag railway station.

Use Mouse and Keyboard with Android Phone
Tired of typing in that small screen of smartphone just connecting keyboard to your smartphone makes it so simple.
I have typed C programs,text documents,played games and done many interesting stuff with smartphone.

I was unable to send the messages to anyone in my Moto G2 Android Phone. Every time I tried to do so, I got the error and an exclamation mark just like following image.
Upon contacting the Customer Support of Airtel I was informed that I should confirm the Message Center Number to them so that they can check if it is correct or not.
Message Center number is responsible for routing your messages through Service provider to the intended recipient. I tried to find it in settings but to no luck. Earlier it was really easy to find the Message Center number but things have changed now. These days Motorola phones (not sure about others) kind of PING the service providers when you insert the sim to fetch the Message Center Number. In response the service provider sends back the Message Center Number that Phone registers in its Registry kind of. That’s why I wasn’t able to find it easily.
Let’s see how to reach there and make the changes if needed.
- Type *#*#4636#*#* in the Dialer.
- Following Screen should show up. Tap on Phone Information.
- Scroll down and have a loot at SMSC:. This is where Message Center Number is inserted.
If you click on Refresh, phone will fetch the current message center number and it will show up here. This is what I told the Customer care executive that she confirmed is wrong.
She gave me another one and I put that in the open area next to SMSC: and clicked on Update. This fixed my issue. Just look at the first screenshot again, you will realize that I am able to send the message now.
