If you feel the phone is too hot, we suggest to launch Hi-Manager, and optimize memory, after part of background app terminated, the temperature will be lower.
The metal body is too hot!
Compare with plastic, metal conducts heat more easily. So phone with metal body is not prone to overheating crashes and other failures. Then it’s more safety, no need to worry about metal back-shell is hotter than other phones.
If you are living in west Africa, because of the weather is too hot, the temperature of phones will be higher than in other regions.
I do not like phones with metal body, I prefer phones with plastic shell.
Advantages of metal body:
1. Because high strength of the metal, metal body have more compression, tensile & kink strength; then the mobile phones have a longer life;
2. Because high hardness of the metal, metal body can resist more scratch & grazing; then the mobile phones is more safety;
3. Compared to general plastic shell, metal material body can upgrade style of visual sense. Most high-end mobile phone use a metal shell.

2. Signal strength is indicated by the signal indicators at the left side of the phone's display. These indicators move up as the strength of the signal increases and down as the signal decreases.
3. To increase your phone s signal strength, try moving your phone slightly, or move towards a window if you are calling from inside a building.
4. If the phone s profile is set to Silent, Flight, Offline, or any other profile where ringing is silenced, it will not ring.
5. Change the profile to General or Normal as instructed in the user guide. Check also the settings of your active profile, especially Ringing tone, Ringing type and Ringing volume.

What is PIN number and what to do if SIM gets blocked?
As soon as you insert a SIM Card in any Handset it asks for PIN (Personal Identification Number) which is a password that is known to the authorized user only. The PIN code can be set to protect your SIM card from unauthorized use.
To prevent continuous attempts to "guess" the PIN number the SIM card automatically gets locked-up after three consecutive wrong entries. If the SIM card is locked-up, the "Blocked" message will appear and an unlocking code will be needed. Further repeat wrong entries of PIN may lead to damage of card.
The blocked SIM can be then opened through PUK number (PIN Unlocking code) which can be obtained from your service provider after establishing your identity. The PUK is an 8 digit code available with your cellular service provider. Also one should remember that 10 times successive wrong entries of PUK number may damage the SIM card forever.

How To Fix The Problem of Phone Gets Hot?
The biggest concern here is that there could be something physically wrong with the battery, and it is overheating – this in turn can lead to battery drain problems or worse. One way to check for battery problems is to remove it from your phone and place it on a flat surface. If it spins freely when you rotate it (try turning it over as well), the bulge that makes this possible is indicative of a problem that needs to be addressed. It could be a simple matter of buying a replacement battery, but it's worth taking your phone into an authorized repair shop to get it checked out.
If your battery seems to be physically OK, it's worth checking that your phone and all of its apps are fully up to date. To ensure that you have all of the latest updates for your phone, head to the More section of Settings and tap About Device. Now tap Software Update followed by Update. Download anything that is detected and you can then check for updates for your apps. Fire up the Play Store app, head to My apps and hit Update All to grab any available patches. Having the latest versions of your apps is always a good way to save battery life.
How To Check For Android System Updates?

How to Cut, Copy and Paste?
This looks simple but can be tricky sometimes when you use different apps. In general, these steps can be used in Email or some other apps:
1. Double-tap or touch-and-hold to select a word.
2. Drag the handles to adjust the area if needed, then tap Cut or Copy.
3. Tap an insert point, and drag the handle to adjust it if needed.
4. Select Paste (Hint: tab the handle when the 'Paste' button doesn't appear).
Note: When working in a web browser such as Android's Browser, use touch-and-hold to select a word since ""double-tap"" has been used to enlarge or reduce a webpage.
How to extend your battery performance?
1. If your phone has an AMOLED screen (like most Samsungs), use a dark colored background, because AMOLED screens only illuminate the colored pixels. Black pixels are unlit, so the more black pixels you have, or the more darker pixels, the less battery you need to light them up.
2. Using darker app backgrounds/themes and darker launcher themes will further prolong your battery life (if your device has an AMOLED screen).
3. Don't use display auto-brightness. It may sound good, but auto-brightness is usually way brighter than you really need. It's much better to manually set a super low brightness level that is still comfortable, and then just bump it up when necessary. This is one of the main ways to improve your battery life as the screen is one of the biggest battery suckers.
4. Switch off vibrate. Unless you really need that added awareness, turn off vibration. It actually takes more power to vibrate your phone than it does to ring it. Turn off haptic feedback too. Sure it feels cool, but it doesn't really add anything to your experience, and it's another battery drainer.
5. Only use original batteries or respected third party manufacturer batteries. Saving a few bucks on a battery that might damage your beloved smartphone is a poor choice indeed, and may also deliver sub-standard battery performance.
6. Set your display's screen timeout to as short a time as is practical for you. Just think, if your screen timeout is set to a minute, it'll use four times the amount of power to have it on, every time you switch your screen on, than if your timeout is set to 15 seconds. Studies report the average smartphone user turns their smartphone on 150 times a day, so anything you can do to limit that frequency (through self-control or other methods listed below) will help keep your battery running for longer.
7. Set ''sleep times'' or ''blocking mode'' to switch off Wi-Fi and mobile data when you don't need them. If your phone is basically off limits at work, set your device to not ring, vibrate or connect to the internet while you're at work. Likewise, you can set your phone to airplane mode when you're asleep or use sleep or blocking modes to set up limits for what your phone does during certain times of the day, whether that's while you're asleep, at work or in a meeting. Get to know the specific settings your ROM offers. Not only will you have to fiddle with your phone less throughout the day (or night), but you'll be saving on battery life too.
8. Turn off smart features like air gestures, smart scrolling and the like, especially if you have a Samsung. Unless you really use these features every day, they're just using battery power for a feature you don't use.
9. Turn off GPS, Bluetooth, NFC, Wi-Fi and mobile data whenever you don't need them. Turning off location data, or setting it to use Wi-Fi or 3G data rather than GPS works perfectly well. Only turn on Bluetooth and NFC as long as you need them, and there's no need to have both Wi-Fi and mobile data turned on at all times. If you use Wi-Fi a lot though, say at home and at work, then it makes sense to keep set your Wi-Fi to ''Always on during sleep'' as this uses less power than to have your Wi-Fi reconnecting every time you wake your phone.
10. Use lock screen widgets or notifications if your ROM supports them, or install an app that does it for you like Dynamic Notifications. You'll be able to get basically all your content without having to unlock your phone fully and navigating around. You still need to light your screen up, but you'll have it on for much less time than normal. If you have an AMOLED screen device, using a lock screen notification app with a black background can save your battery life significantly.
11. Ditch widgets you don't really need, especially those that are connected to the internet like weather widgets.
12. Keep your apps updated. There's a reason developers constantly update apps, and many of these reasons are memory and battery optimizations. Keeping your apps updated also means you have the best optimizations available. Likewise, delete old apps you no longer use, as these may be running background processes that chew up RAM and battery life.
13. If your phone has a battery or power saving mode or other battery management option, make use of it.
14. All ROMs, whether it's stock Android, OEM UI's like TouchWiz or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption here and there. Find these various options for your device and ROM and make them work for you!
15. Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every fifteen minutes, just go into yourSettings and Google account and turn off auto-sync for those apps you don't need constantly updated.
16. Set apps to update only when you launch them. If you rarely (or very frequently) open an app, it might be better to only have it update when you do so, rather than updating automatically all the time via push notifications or sync intervals. If you only check email once a day, why not let the app update then only, and if you're on a widget or app every couple of hours anyway then why not have it update each time rather than every fifteen minutes when you're not even looking at it.

What is the Difference between 2G and 3G Technology
Second Generation (2G) technology was launched in the year 1991 in Finland. It is based on the technology known as global system for mobile communication or in short we can say GSM. This technology enabled various networks to provide services like text messages, picture messages and MMS. In this technology all text messages are digitally encrypted due to which only the intended receiver receives message. These digital signals consume less battery power, so it helps in saving the battery of mobiles.
The technologies used in 2G are either TDMA (Time Division Multiple Access) which divides signal into different time slots or CDMA (Code Division Multiple Access) which allocates a special code to each user so as to communicate over a multiplex physical channel.
3G technology generally refers to the standard of accessibility and speed of mobile devices. It was first used in Japan in the year 2001. The standards of the technology were set by the International Telecommunication Union (ITU). This technology enables use of various services like GPS (Global Positioning System), mobile television and video conferencing. It not only enables them to be used worldwide, but also provides with better bandwidth and increased speed.
This technology is much more flexible as it can support 5 major radio technologies that operate under CDMA, TDMA and FDMA. CDMA accounts for IMT-DS (direct speed), IMT-MC (multi carrier). TDMA holds for IMT-TC (time code), IMT-SC (single carrier). This technology is also comfortable to work with 2G technologies. The main aim of this technology is to allow much better coverage and growth with minimum investment.
Figure: Evolution of Mobile system from 2G to 3G
Difference between 2G and 3G Technology
· Cost: The license fee to be paid for 3G network is much higher as compared to 2G networks. The network construction and maintenance of 3G is much costlier than 2G networks. Also from the customers point of view the expenditure for 3G network will be excessively high if they make use of the various applications of 3G.
· Data Transmission: The main difference between 2G and 3G networks is seen by the mobile users who download data and browse the Interneton the mobile phones. They find much faster download speeds, faster access to the data and applications in 3G networks as compared to 2G networks. 2G networks are less compatible with the functions of smart phone. The speed of data transmission in 2G network is less than 50,000 bits per sec while in 3G it can be more than 4 million bits per sec.
· Function: The main function of 2G technology is the transmission of information via voice signals while that of 3G technologies is data transfer via video conferencing, MMS etc.
· Features: The features like mobile TV, video transfers and GPS systems are the additional features of 3G technology that are not available with 2G technologies.
· Frequencies: 2G technology uses a broad range of frequencies in both upper and lower bands, under which the transmission depends on conditions such as weather. A drawback of 3G is that it is simply not available in certain regions.
· Implication: 3G technology offers a high level of security as compared to 2G technology because 3G networks permit validation measures when communicating with other devices.
· Making Calls: Calls can be made easily on both 2G and 3G networks with no real noticeable differences except that in 3G network video calls can also be made. The transmission of text messages and photos is available in both the networks but 2G networks have data limit and the speed of the data transmission is also very slow as compared to 3G.
· Speed: The downloading and uploading speeds available in 2G technologies are up to 236 Kbps. While in 3G technology the downloading and uploading speeds are up to 21 Mbps and 5.7 Mbps respectively.
