Hello Ani, diffused here with a Curve 8330 OS 4.3.
Downloaded this SMS app this morning and tried it out this afternoon. Upon opening it looks and acts just like the native app. I don't see anything anyone else sees. Install was successful as I see it in my applications list.
Upon opening, it sent and received fine, except I could not delete any messages in SMS or my email. I did a battery pull and it was OK except after a couple messages it did it again.
I received an error popup on my homescreen that seemed to continue throughout the day. It said, "Uncaught exception, jav.lang.NoClassDefFoundError".
I also could not delete emails or forward emails. I didn't get a chance to do much else with forwarding texts but I could reply OK. I know this isn't for email but would it make a difference that I DO have the Empower Email Viewer instllaed on my device?
Now this evening, everything seems to be operating with all normal functions. No more popups and I can now delete both SMS and emails.
I have never had any of these issues come up before since owning my device. I've had it for maybe 9 months.
I'm not sure what else to say so I'll say goodnight. I'll try more tomarrow since I will have more time.
Let me know if there is anything else I can be doing to help here, otherwise I'll continue to check it out and post here.
