[AT&T Samsung Galaxy Note I717] techntrek:
I thought we could list useful apps we've installed, and a quick summary of why. While browsing the Market I see a lot of comments "doesn't work with X", so I figured since we are blazing a new trail with our Notes we can save each other some aggravation and list ones we've found that definitely work.

Missed Message Flasher by TomatoX. Calendar only gives you one notification of an upcoming appointment, this lets you get multiple notifications until you stop it. Works for missed calls, texts, calendar and many others. I found the test notification in the setup does NOT work, but it does work for a real appointment. Haven't tried it with texts, calls yet. Edit 2/21, so far it doesn't appear to work with texts, let me know if you find otherwise. May try other options tonight. Edit 3/5, I'm still not sure I'm getting repeated notifications for anything other than calendar items, still testing.

Opera Mobile by Opera. Can't stand that the built-in browser can't identify as a desktop browser, but Opera Mobile can.

GPS Status & Toolbox by EclipSim. Nice real-time verification of all of your GPS stats, accelerometer, level, compass. Nice bonus, shows battery stats too (temp, %).

HotSpot Toggle by Mehdy Bohlool. One-click activation of the wifi hotspot. A little annoying that it doesn't line up with the other icons on the home screens, but it works.

XiiaLive Lite by Visual Blasters. For streaming ASX/WMA. I have a lifetime Internet account with SiriusXM. The sound quality from XiiaLive is much better than the SiriusXM app - the bit rate from the Sirius app is awful. I'm using this with a free online service called MusicDock. Use their "Windows Mobile" site (mentioned at the bottom of their home page) along with this app and you are golden.

Equalizer by Smart Android Apps. Simple, but works to modify the audio output, including on Blutooth.

Added 2/22

Battery Indicator by Darshan Computing. Same as Battery Percentage but is half the size (1/2 MB vs. 1 MB) and is easier to read IMO. No way to modify the stock indicator w/o rooting, so for now I'm using this instead.

CPU Spy by storm717. Very small. Lets you see how much time your CPU spends in each speed, including how much time it sleeps. If your battery is draining quickly this will let you see if it is ever sleeping.

Added 2/29

Word Feud by Berthussen IT. Scrabble-like game.

Added 3/05

AirDroid by SAND Studio. Way better than Keis Air - ability to transfer files, txt messaging, etc via wifi.

Music Volume EQ by K & K Design. Works well, autostarts, includes features other than just a basic EQ.

AndroSensor by Fiv Asim. Displays outputs and current draw from all of the sensors in the Note, including barometer.

Added 3/13

Screen Filter by haxor industry. Much more effective than using Dimmer (listed below). Allows you to dim just as much as you want, or as little as you want. So you can go really dark at let's say 20%, or if you just think the stock auto-brightness is a little too bright, you can permanently apply a 75% filter to dim it down just a little and still let the auto feature do its job. I'm currently trying that. Only problem is as you get to the really dark settings you get a noticable gray coloration to the whole screen - minor and an acceptable trade-off. You can set up multiple home screen shortcuts for multiple settings. Can work along with Dimmer but it is pointless, I just uninstalled Dimmer.

Added 3/23

Screen On by Konstantinos Polychronis. Keeps the screen on for selected apps, or when charging. For instance, Google Maps where you don't want the screen to turn off (and loose your position). This is a tentative recommendation - at first it was flaky (didn't keep the screen on) for some apps but seems to be better after rebooting. I'll report back after a while. After selecting your applications from the list don't forget to enable the application with the checkbox in the upper left corner.

Calendar Snooze by Bitfire-development. Adds lots of snooze options to calendar notifications, more initial notification options and more reminder notification options. I still use Missed Message Flasher for text and Google Talk, but I turned off reminders for calendar in MMF and use Calendar Snooze instead. Mostly because it allows you to set a pattern for vibrate instead of having just one long vibration. I notice it better when it pulses several times.

Added 4/9

Increasing Ring by sashomasho. Increases the volume of your ringer and/or clock alarm, so you can start off completely silent or nearly silent and increase the volume over time. Gives you a chance to grab your phone and answer or reject a call without it blaring at top volume on the first ring. Note that it increases the volume based on your current ring setting so make sure you turn your ring volume below full volume or it will appear that the app isn't working.

Can recommend but don't use anymore

Dimmer (Night Mode) by geekyouup. One-click ability to dim your display as far as it will go. The stock brightness slider will only take you to "30", this takes you to "10". A noticeable difference especially in a dark room. Screen Filter (listed above) works much better and is more versatile so I removed this app.

Can no longer recommend

Equalizer by Smart Android Apps. Would randomly stop modifying the audio stream even though the app was still listed in the task manager. Also had to re-start after every reboot. Found another equalizer (listed above) which doesn't have either problem. Also I think it sounds better.

SiriusXM Internet Radio by SiriusXM Radio Inc. Doesn't let you force a specific quality, and found an aftermarket solution (listed above) which sounds much better.

Battery Percentage & Temp by Global Developers Adds a battery percentage display as a permanent notification. Battery Indicator (above) is easier to read and the app is half the size of this one.
