This is about to change when next month arrives but not from Samsung. Third-party firm Zens has announced its wireless charging solution for the Galaxy S3 which will arrive in September, according to PocketNow.
Zens said: "The power receiver solution is neatly integrated in the Zens battery cover for the Samsung Galaxy S3. Simply replace the standard battery cover of the Samsung Galaxy S3 with the Zens battery cover and the phone will work seamlessly with the Zens Wireless Charging pad,"
This does mean swapping your existing rear cover and swapping it with one sporting a Zens logo instead of Samsung. Thankfully Zens has created two covers to match the pebble blue and marble white colours of the S3 - not so great if you've got the Samsung Galaxy S3 Olympic edition though.
The firm also makes a wireless charging products for the Apple iPhone 4/4S.
Until Samsung gets round to launching its own wireless charger, and S Pebble mp3 dongle which also hasn't turned up, the Zens wireless charging pad and battery cover will do the trick. There's no price or exact date yet so stay tuned.
