Re: my screen has gone blank and i cant get contacts from the phone
If the contacts were Google contacts (as they should always be), they're at Google Contacts.
If not, you'll have to find a shop that will temporarily plug a screen into your motherboard, so you can export your contacts, import them as Google contacts and let them sync.
There are two possible reasons for the blank screen. Probably it is a faulty display or some issue with the PCB. You have to get it checked my 6the nearest service center to get it fixed
