With android 4; 6 works as sound adjustment. In the instructions link to paid applications. Check on other applications is not possible. It is not clear whether it works or not (for me useless goods) Do not miss the benefit: return part of the cost of the goods back. Register on the link bar code, activate the cash store, make purchases in this store, take the goods and confirm the delivery. Enjoy the benefits. Accumulate or immediately transfer to the phone, accounts, cards, electronic money. Activate the cache is also possible from the application for mobile devices or through the addition for the browser. I use this service for more than 3 years is not the best yet. More profitable than other known service. Register, do not miss the benefit!!!
