2. Remove the battery.
3. After a few seconds, put the battery in and switch your phone on.
For phones with non-removable battery:
1. Press and hold the power button until the phone vibrates and switches off.
2. Switch your phone on again.
Reset the settings
Restore the original factory settings as instructed in your phone's user guide.

Check the following:
Charging times differ between charging models. USB charging is limited by the maximum current output of the USB device, and may take longer than charging with conventional chargers.
Note: all batteries including high-quality batteries like Nokia's will eventually lose power retention capacity. If it is time to replace your battery with a new one, be sure to purchase an original Nokia battery from an authorized Nokia dealer.
Both earpieces (Right/Left) are used when the Bluetooth Advanced Audio Distribution Profile (A2DP) is activated when listening to music or watching a video. When you make a call on your Nokia device while using a Bluetooth headset, the Hands-Free (HFP) or Headset (HSP) profile would be activated. Only the Right earpiece is used at this time. This is a Nokia safety feature as the headset may be used in a vehicle as a Hands-Free device. This allows the user to still hear the environment around them while on an active call.
If you forget or lose the lock or security code, try first the default lock code 12345. If it is not accepted, contact the nearest Nokia Care point to unlock your device. To find nearest location to you, go to your local Nokia website, and navigate to Support > Troubleshooting (or Repair & Recycle).

All Nokia phones are tested for heat tolerance in accordance with industry and government standards. All models meet industry standards before they are offered for sale. Only Nokia models that meet heat tolerance standards are on the market.
Many phones may seem warm to the user, like most battery-powered devices during excessive use. Higher level phones such as 3G phones, or phones operated in many modes at the same time, such as phone, internet and GSM, will seem warm to the user. Warming may also happen during charging or when listening to music for a longer time, for example. Certain phones only used in talk mode may also seem warm to the individual user.
However, the heat level on all Nokia models is within the safe range. The phone does not require repair since it is operating safely in the manner designed to operate.
