I am Pete, and I'll be happy to assist with your question.
Can you please let me know:How old is the Galaxy Ace?
Almost three years old.
Ok, there are four possible causes of this problem:1. The charger is defunct (you have already rules this out by replacing it)2. The charge connection on the phone is dirty or damaged.3. The battery has failed and needs to be replaced.4. The charge circuitry inside the phone is faulty (unlikely).
As you have already tried using a different charger, the problem is most likely with the charging connection on the phone.
Try cleaning it out with compressed air to ensure there is no debris trapped in it that is impairing the connection.
Also try wiggling the cable a bit when it is connected to the phone.
If it intermittently shows that it is charging when you wiggle the cable, then you know that the connection on the phone is bad and it will need to be replaced. A local electronics repair shop can do this for you.
If it still shows no signs of charging, then the battery may be worn out - try fitting a replacement battery.
If it won't work with a new charger, new connector, and new battery fitted, then the phone itself has a fault.
I was able to switch the phone on yesterday so that probably rules out the battery. I have used compressed air and tried wiggling it about but to no avail.
Ok, I would still suspect the connector itself on the phone.
After three years, it has seen a lot of use. And over time, it gradually wears out and no longer makes a good connection with the charger cable.
The next step will be to have the connector replaced.
This is a common problem with phones - they are really only designed to last around 2 years, and the connectors have a life of around 1000 uses, however they don't always last that long.
If you have the appropriate electronic reworking equipment, you could even carry out this repair yourself:http://www.youtube.com/watch?v=YxxpLYf16fc
Or if you need me to recommend a local electronics repair shop to do it for you, just let me know what postcode area you are located in.
You are probably right, Pete, but I had paid my £22 in the hope that my phone would be working again. I am going to ask for a refund - it is not personal - I hope you understand
