OE - in this case, the android Ebay app is vastly superior to simply browsing to Ebay on a phone.

I'm running the S3 version of the phone with the same android version and all is well but I'm on a 4G network so its hard to tell if the OPs problem is an older phone, an older app version, a 3G network or something else.

I suspect if it was the network or a real issue with this android version, we'd have read more about problems.

OP - you might want to ask about this on an android forum since I imagine quite a few people there will use the Ebay app.
