Samsung Galaxy S3 not turning on

Views: 429 Replies: 4
Last week, my Samsung Galaxy S3 had a black screen in the morning and refused to turn on. Thinking the battery had not charged correctly, I swapped it for a spare fully charged batter and still it would not come on. Volume down, power and home key is not doing anything.

I left it plugged in for a few days and yesterday I saw the screen displaying a battery icon, but not the normal battery icon you get when its charging, probably its the one you get when you 1st put insert a charging cable to a phone with an empty battery. I hit the Power On key, but it would not come on and the battery icon vanished & has not come back. There are no lights on the phone or noises at all.

I was wondering what your thoughts were on what the issue could be ? I am out of warranty, so I would like to try to estimate the fee before taking it in, I have a kind of backup. It seems Samsung Kies doesn't backup the sim contacts and Samsung Smart Switch I think I need a working Samsung S3 to restore that to.

My phone has never been wet, badly treated or rooted. Thanks for all your assistance.

Welcome to MobiFAQ! How certain are you that the spare battery still held a charge? If you're sure of it, then it might be a motherboard issue. Have you already tried holding the Power button for about 15-20 seconds?

Hi many thanks for the response.

I've tried holding the Power button, but there is no response. The spare was probably ok, but maybe its drained by now. I will probably take the phone to the shop and see what they say.

Is there a way to access my Samsung Smart Switch backup, without having a Samsung Galaxy S3 phone ? There's some contacts I'd like to get at.

If the contacts are already backed up to Smart Switch, you should just be able to run it and see the contacts. Also, if they're Google contacts (not Device or Phone contacts - the default is Device and you have to change it to Google when you enter a new contact), they're backed up at Google Contacts.

Hi, that's really handy, having them already on Google contacts, wasn't aware of that. Thanks so much !

I can't get anything from Smart Switch, as it wants the Hardware attached, which I don't have. It would be good to get my text messages, music etc back in the interim onto my temporary phone. This is the screen I get to :
