Some points to remember:
Wi-Fi tethering : Tethering is connecting one device to another. In the context of mobile phones and tablet computers, tethering allows sharing the Internet connection of the phone or tablet with other devices such as laptops. Connection of the phone or tablet with other devices can be done over wireless LAN (Wi-Fi), over Bluetooth or by physical connection using a cable, for example through USB.
If tethering is done over Wi-Fi, the feature may be branded as a mobile hotspot. Mobile hotspot is a feature present in smartphones nowadays which lets you convert your smart phone into a portable router. One can setup a password protection to it easily so that no one without the password can connect to your smart phones. The Internet-connected mobile device can act as a portable wireless access point and router for devices connected to it.
Bluetooth: Bluetooth is widely used for communication between smart phones and other accessories or between PDAs and information kiosks. Various versions exist as given below:
Bluetooth 1.x: Capabilities - Basic rate bluetooth (that would be about a theoretical maximum of 1 Mbps data rate)
Bluetooth 2.x: Capabilities - Basic rate + EDR (that would be about a theoretical maximum of 3 Mbps data rate; optional), EDR: Enhanced Data Rate.
Speed 24Mbit/s (4.0) ; 24Mbit/s (3.0+HS); 3Mbit/s(2.0)
Bluetooth 3.x: Capabilities - Basic rate + EDR (optional) + HS (optional) Speeds up to for +HS: 24Mbit/s
Bluetooth 4.x: Capabilities - Basic rate + EDR (optional) + HS (optional) + LE (optional)
LE stands for Low Entergy.
Bluetooth Range: Among different bluetooth specifications, there are 2 most popular classes (types) of devices:
Class 1: range up to 100 meters (in most cases 20-30 meters)
Class 2: range up to 30 meters (in most cases 5-10 meters)
Configure Screen lock : Our smart phones carry a lot of personal information. All of your text messages, emails, notes, apps, app data, music, pictures, and so much more are all on there. While it's a very great convenience to have all of these on your phone, it's also a major security risk if all of this data is easily accessible. The best way to prevent simple unauthorized access is by setting some sort of lock on your phone. Two popular choices, especially on Android phones, are passwords and pattern
POP3 and IMAP Connection :
POP3 : Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline. You can set up your mobile phone to send and receive email from your email accounts. Using POP3 (Post Office Protocol version 3 ), your email are retrieved and stored locally on your mobile phone and at the same time they're deleted from the server. It is therefore not possible to access your email from different devices.
IMAP: The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers."
Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by multiple users."
