I bought this phone as a replacement for my Samsung 8500, (a phone that has served me extremely well over the last three years). I researched many many phones before I decided to get this one.I am rather disappointed with this phone for several reasons.1. Signal strength meter consistently at 1 or 2 bars only. I very rarely ever see more than two signal bars, but I don't have many problems with making calls, and it does better making a call in known weak areas than the 8500 did. The thing is, I only know where the weak areas are from past experience using my 8500. I sure wouldn't know where the weak areas are by looking at the signal strength on this phone, it's ALWAYS low.2. When using a headset (which is how I make about 90% of my calls), the person I am talking to tells me that I keep cutting out (digital packet loss). The problem is worse if I am in a weak service area. If I unplug the headset and hold the phone to my ear, they can hear me fine. The problem is NOT the headset. I have several headsets, and they all do the same thing. Also, although the handset has a good volume level, when I use my headset, I can hardly hear. My 8500 was usually too loud, but could be turned down. I never had any problem with hearing or being heard with any of my headsets on my 8500 unless I was in a bad service area.3. Call timers... What call timers! They totally did away with them. Other than the CURRENT call you are on, there is NO history of how long past phone calls were. Once you hang up, it's gone... FOREVER! It makes it difficult to bill for my phone time when I cannot go back into the call history to see how long a phone call was. As far as I am concerned, with the amount of memory the modern day phones have, there should be a cumulative call timer for every listing in your phone book, and possibly even in the caller ID list. The phone should have the length of the call listed for every individual inbound and outbound call. The lifetime counter (odometer) is completely gone too. Why!?!?4. Major software bug. Text messages cause a ghost data session. Anytime I receive any kind of text message or e-mail, I cannot make an outbound phone call without having to log onto and then off of the internet or power cycle the phone. It totally defeats the purpose of having someone hit 2 in voicemail for the caller to have their caller ID number sent to your phone as a text message. When you go to read the message and hit the button to call them back, it says you cannot do that until you press end to quit the data session. When you do that, it still does not end the data session. This is a MAJOR problem for me as I receive a majority of my messages via caller ID and text messaging.5. Ringers do not stay where I want them. I leave the phone on vibrate most of the time, however, if you leave the flip open, it turns escalating ring (louder the longer it rings). If you have it plugged into the charger, it just goes into straight ring on extremely _L_O_U_D_! This is beyond annoying when you are trying to sleep.6. Wireless web. Although the speed of the 3G wireless web is impressive, many of the features that I used to be able to get into with the 2G (straight text) wireless internet are just plain gone from the available menus of 3G wireless internet. The ones I used the most, the Sprint wireless web people tried to help me get them back, but some of them just plain and simple will not work on the new phone. I thought that I would be able to get to all of the stuff I got with my old phone plus a whole lot more. Instead, they just removed about 75% of what used to be there and replaced it with subscription &amp; pay based services. The ones that I miss most are Yahoo finance message board and Buzztime trivia. GONE!7. Backlight Part 1. The color screen is very nice, however the controls for the brightness could be a bit more flexible. First of all, there should be some way to get light into the phone other than strictly from the backlight. When I try to look at the phone during a call, the display is completely black. It is NOT possible to read anything on the display without the backlight. (The outside display CAN be read without the backlight)8. Backlight Part 2. I leave the screen settings in "power save mode" most of the time, because the display is just too bright (especially at night). The bad part about using "power save mode" is that when you do, the keypad lights are turned completely off (a problem at night).9. The outside display is awesome. I love virtually everything about it. I wish that there was an easy way to make the backlight come on to look at the time. While on the subject of time, I don't know why the spinning compass (when searching for service) is more important than the current time. Leave the time up on the screen and do something else for searching for service.9. The camera is easy to use, does well in poorly lighted rooms, quality is decent, and the "fun frames" are pretty cool.
