However, its beauty was soon marred by rather serious problems interacting with the Play Store. Searches would hang the whole system after entering the second letter in a search term. Manual updates would likewise hang the entire system. Auto-updates would never install.
After ~90 minutes of testing and troubleshooting, I have confirmed that the issue is Swype being set as the active keyboard while interacting with the Play Store. The work-arounds are to either not use Swype or to make sure that it’s not the active keyboard when performing Play searches or trying to apply updates.
I do not see this issue on my Galaxy Note 5 nor on my wife’s Nexus; the problem appears to be specific to the K1.
Problems like this can be very hard to root-cause analyze, and the tendency for companies like those involved here – Nuance, Google, and NVIDIA – is to point fingers at one another rather than try to find a solution. I am not hopeful for an official fix anytime soon.
