I'm not sure whether these problems applied to all 5800 users but hopefully could find some answers here..

Recently, i just upgraded firmware from v30+ to v40 and i faced a few problems here

1. no response on clicking snooze or cancel button on touchscreen when alarm rings.

2. text ringtone rings from time to time, no messages or text or emails on checked.

3. the phone seems more lag than before.

Anyone facing the same problem ?
