Technically impeccable and visually charming, the iPhone-4 has lost the lead in popularity to its fellow iPhone-4s. But they still have a lot in common.
When replacing the iPhone-4 speaker is mandatory?
The sound emanating from the phone's polyphonic speaker sometimes loses its juiciness and the ability to give pleasure with a pleasant tone. It's all to blame for water, mechanical damage, and even frequent use of the phone as a player at the maximum volume level set. Of course, factory marriage should not be discounted either, despite Apple's impeccable reputation. Replacing the iPhone speaker in this case is an inevitable process, which after reading the article will become an understandable and elementary action for you.
Where can I get a speaker for a hoarse iPhone?
Today such a question is solved quite easily. In almost every city there are specialized stores selling components for mobile phones. In the absence of such, you can resort to the help of a mobile phone repair shop, in which replacing the iPhone-4 speaker is a common work operation. This fact simply obliges the workshop to have the required component in stock. Most likely, you will not be denied the sale of a much-needed part. The only difficulty can arise only if you are not sold the original speaker, but a copy of a third-party manufacturer, which can significantly affect the quality of the reproduced sound and, of course, the durability of the work. Usually a copy is much cheaper than the original.
Preparing the place and working tool
The place where the iPhone-4 speaker will be replaced must be chosen as convenient as possible. You should not be located in the aisle or near the doors, as at the most crucial moment you may be hindered or accidentally pushed. The surface of the table should be flat and without unnecessary objects, and the lighting should be sufficient so as not to strain your eyesight. Of the tools you will need: Phillips and iPhone-pentalobe (star) screwdrivers, tweezers and a plastic spatula. The last element is only desirable, since it can be replaced by a regular plastic card (it is needed to disconnect the cable connectors and protective screens).
Step-by-step instruction: direct replacement process
Replacing the iPhone-4 speaker is done in stages. All dismantling operations are described with the phone facing down.
