My consuming MB quickly when I opened data

@bolbakam not much of a hardware repair issue here. This sounds actually pretty normal since data does consume your memory (storage) rapidly. This all sounds like a software issue. Check for any Apps that run in the background. Make sure that you start your phone with the least amount of Apps working.

If it still does use the memory at a rate higher than ever, you want to try a factory reset. Before you do that, you should backup all of your files (pictures/music. contact. etc) since a reset will delete all of that.

You also need to know the email and the username/password that was used when this phone was originally set-up. If you don't have this, you will not be able to access your phone after the reset. Don't do it!
