First of all, the Quark Android Wallet was updated by Hashengineering on June 21st - check it out here:

Lastly, after a couple of setbacks, we now have been working with the pacatum coding group (http://btc.pacatum.com/) and they have worked diligently to complete the lions share of the coding related to the coming update which will change Quark from POW to Hybrid POW/POS.

It is true that the Quark Wallet for android has been updated by Hash Engineering (as that is me). Many users have reported several problems such as freezing screens and on older android devices the app never syncs with the Quark Blockchain (meaning it takes forever). For instance on my own Android 4 and 7 devices (app installed on June 21) it has been nearly two weeks and it is only at block 3 million. This could be fixed with an update to the app by building a checkpoints file. Unfortunately, building of the checkpoints file (requires downloading the blockchain from a client on the same machine and saving headers to a file) is also taking forever on both of my development machines. Based on my own work, I don't know if new users can get this app to work.

If Quark is changing to a POW/POS hybrid that will definitely break the app if it isn't already broken. The app will not support any POS blocks. As soon as one is included in the blockchain, the app will reject it and the app will be stuck on the previous block. Fixing that will require a ton of work (it has been done by the peercoin developer), but it requires a special block explorer (also made by the peercoin wallet for android developer). Hash Engineering will not be doing this upgrade.

The bottom line is that given this knowledge, users should transfer their coins from the Quark Wallet app to other addresses maintained in other Quark wallets.

In the near future I will be taking the Quark Wallet app off the Google Play store to prevent new users from losing coins.

But is it possible for the right bounty?

Depending on the success of the qrk come back right now in progress could you do this if required for the right reward? How much would you have to do from scratch and how much could we borrow from ppc?

Sure the right bounty can fix it. However, the special block explorer is not something that I do. Many have asked for POS wallets for android and none have provided a working block explorer for the app to use. This project will require several expert developers.
