When it’s time to upgrade to a new phone it’s important to delete the information on your old one to help keep your private information such as email addresses and contacts safe

To format your phone and delete all the information in the memory there are two options.

The first should work for most recent Nokia phones:

1. Dial *#7370#
2. Type in your lock code. The default number is 12345. (If you’ve changed this number and forgotten the new one, this format
method won’t help)

the phone will restart back to the original out-of-the-box settings and your information will be wiped.

The second method works with the Nokia 5800 V. 20.0.012

1. Turn your phone off
2. Press power button to turn on
3. As the phone starts booting up, hold down the red and green buttons on the front together with the camera button on the side.
You’ll still need your lock code for this method

Once restored to factory settings, don’t forget to remove your SD card and SIM.

To remove the SIM and SD card:

1. Take off the back cover by putting your thumbnail in the notch on the back at the bottom and pulling backwards away from the phone. The back cover will open like a book as opposed to sliding open
2. Take out the battery
3. Open the side access doors (they’re on the left-had side as your looking at the phone from the front
4. Push out the SIM card by putting the stylus into the hole under the battery compartment
5. Push the SD card in with your nail or the stylus and it will pop out

It should now be ready to pass on

When you boot your HTC phone with Andriod operating system, it’s a fair bet that you’ll have a whole load of applications starting that you don’t need or want to run.

There is, however, a very simple and quick application that allows you to disable start-up processes very easily.

Simply download ‘Startup Auditor’ and install. You will now be able to choose which applications start-up when your phone boots.

The software has a trial version with ads (and other restrictions) but the paid-for version also has a trial period. To buy it costs around 63p (at the time of writing)
