Ok so I bought my first android and wondered as im not tech is there anything I should know?

Ive heard the androids can eat your credit away if you dont disable automatic dls. Is this true?

Shouldn't do - just make sure you've gone into Play Store settings and have set Auto-Update Apps to "Wi-Fi only"

Only if you set it up to download updates, or check email frequently, or download apps that frequently sync. Out of the box, they should be fairly light users of data. By once you install Twitter, Skype, Whatsapp, Facebook, Angrybirds, etc, etc, you need to monitor default settings and usage.

Be careful of some free apps that are ad supported. They might be downloading a new ad every few seconds (For a while, Angrybirds was doing this, but I think they fixed it).

By credit do you mean data allowance or do you mean in app purchases?

Say for instance I have 8 pounds credit and I top up 10 pounds so it makes 18 pounds credit. Whats what I mean.

most modern phones will use data in the background. unless you turn it off.

if you are on PAYG you need to ensure you have a data tariff or turn of cell data.

At the moment im on a pound a day for 50mb i think.

I only really will be using the net while im at home so dont want it downloading stuff when im out and about and using my data up.

You'll certainly need to be careful there. If you're on one of those tariffs that charge a pound a day even if you download a tiny amount of data that day, you'll probably be safer to turn off mobile data altogether and only switch it on when necessary.

This is easy to do by swiping down from the top of the screen and switching off the mobile data toggle.

Edit: you'll still be able to browse and download over wifi both at home and using hotspots when out.

If i was you, I would switch to another tariff/operator.

Just turn off mobile data . Simple .

If you want to check your Facebook one day whilst out and about , just turn it on .

Then turn if off again when you have finished . It can't use your credit if it's disabled

You can stop your apps updating while you are out and about by going into the Play Store selecting Menu and select Auto-update apps over Wi-Fi only or disable all updates.

Not sure how it works with PAYG, but if possible add some type of data tariff to it

I have had these where they charge £1 and it quickly adds up if you use any data (even a small amount)

IMO, A smartphone needs data to get the full benefit

If you drill down in the EE site, they do a data booster of 500MB a month for 6 months for £20 on PAYG.
