So I've been playing with my PM-325 for about 3 days now and I've noticed a few things here and there both pro and con.
Really nice 128x160 screen. It's also much brighter than my N400.
Compact. The slide out keypad makes it easier to handle. It's still not as easy to hold has my N400 was, but it's not bad.
Decent VGA Camera. Nothing spectacular, but I'm excited to have it.
Clear ringer speaker. Not distorted at high volume like some other phones.
Bluetooth. Currently supports the Headset, Speakerphone, and Dial-up Networking profiles.
Voice memo. It's kinda nice to have. Has a 3 minute total storage.
Compatible chargers. I can keep using my Samsung N400 chargers.
No speakerphone. There's only a "Monitor" (one-way speaker) function, and it's not really loud enough.
Custom ringers are ignored in Roam. When I set a custom ringer for someone, I'd rather that I be allowed to decide if I want a roam ringer to override the custom ringer. I've got a pretty good roaming plan. I don't really care to be notified if I'm answering a call in roaming.
No Bluetooth OBEX profile. It'd be nice if I could sync and share my contacts wirelessly.
Paging through SMS messages is slow. You click the next button to move to the next message and there is a .5 to 1 second delay.
When the cover is slid shut, the screen shuts off after only 3-4 seconds. There's no option to have it stay on for X amount of seconds. So if I get an SMS, I have to check the sceen quick before it goes back out again.
Speaking of notifications, after the screen has shut off, there's no visible indication that there's an event to respond to. What if I walk out of the room and don't hear the voicemail or SMS notification? I'd have to open my phone just to check if I missed something. It really should have the red LED flash until I acknowledge the event.
The service notification sound is so quiet it's nearly silent. The same goes for the call connect/disconnect sound.
Insufficient ringer looping on alerts. If I get an SMS alert, the ringer only plays once. On my N400, the ringer would loop for about 15 seconds. I have to choose longer polyphonic ringers to ensure I hear the alerts when I'm sleeping.
Ringer looping isn't seamless. On my N400 there was about a 1/4 gap in the ringer loop. I accepted it because I figured that the N400 was a poor quality phone (and I've come to accept that Samsung products in general are low quality), and therefore I simply figured a new phone would fix the problem. But I was way off. The PM-325 has HUGE gaps in the loop, and the gap lenghths vary, so you can't really work around them. It's really disappointing.
I'm sure I'll have more comments to come.
