I am satisfied with this phone though I am still learning how to use it. I like it. It is unlocked for real and I can use it with any company and even out of America with other sim cards. Just what I really wanted

Samsung S5230 Tocco Lite Unlocked Phone with Quad-Band GSM, 3 MP Camera MP3/Video Player, and MicroSD Slot--International Version with Warranty (Noble Black) Review

I've had this phone for about a month now, I am fairly pleased with its performance. I am somewhat demanding of my phones and always look to get the most bang for my buck. With the Tocco Lite I can honestly say that it is worth the money. The only complaint that I have got to date is an issue it has with its blue-tooth. I use a hands free blue-tooth earpiece that also has headphones with it the Samsung WEP870, great little gadget, the sound quality is excellent. The problem that I noticed right away is that once you turn off the MP3 player, unless you will use the headpiece, you absolutely must turn off the blue-tooth on the phone as it will eat up the battery within hours. When I did it the first time, the phone glitched. Even though the blue-tooth icon disappeared on the screen, the phone's battery continued to drain at a rate of one bar in about 2 hours. After trying a few things I finally came to a conclusion that the only way to turn off you blue-tooth after you used it with MP3 player is to restart the phone completely. That of-course resets the arrangement of the gadgets(a.k.a. apps for smart phones) and any other system setting that you have changed.
Besides this one little issue, the phone performs fairly well. Oh, another thing, it works pretty slowly if you are trying to use anything else with the MP3 player working.
Hope this is useful.

Panasonic Lumix DMC-G2 12.1 MP Live MOS Interchangeable Lens Camera with 3-Inch Touch Screen LCD and 14-42mm Lumix G VARIO f/3.5-5.6 MEGA OIS Lens (Black) Review

Panasonic Lumix DMC-G2 12.1 MP Live MOS Interchangeable Lens Camera with 3-Inch Touch Screen LCD and 14-42mm Lumix G VARIO f/3.5-5.6 MEGA OIS Lens (Black)

Panasonic G2 is a successor of G1, which is the first micro four third camera. G series focus on make the camera as small as possible without sacrificing image quality and control. G2 adds video recording and touch screen feature.
Panasonic G2 main specs
- 12 megapixel - four thirds sensor
- 3"' 460k resolution swivel and touch screen LCD
- 1,280 x 720 high-definition at 60fps
- Built-in Electronic viewfinder (1.44 million dots)
BODY DESIGN
Panasonic G2 weights 371 g / 13.09 oz body only, 593 g / 20.92 oz with battery, memory card and 14-42mm lens. It has dimension of 124 x 83.6 x 74 mm exclude protusion. Compared to regular DSLR camera, The package is significantly smaller and lightweight. Compare to advanced DSLR such as Canon 7D , G2 is approx. half the size and weight. As a result, it is more fun to carry around and it takes only a bit of room to store.
Like G1, Panasonic G2 has built-in electronic viewfinder which is helpful for composing photos, the rear 3' inch LCD is also very bright and nice to use. It can also swivel so you can compose a picture in unusual angle for example overhead or very low in the ground.
New in micro four third system, LCD screen is now equipped with touchscreen technology. You can touch the screen to select or change various settings and also you can touch the screen to set auto focus point.
Therefore, changing AF points in G2 is very fast. In regular DSLR camera, you might need to scroll around until you get AF point that you want. in G2, you just touch it. AF point could be also be enlarged or decreased for precision.
HANDLING
Panasonic G2 is nice to hold, thanks to the grip. It also has many dedicated buttons and switches. It has one main dial, camera mode dial, Release mode switch, Auto focus mode switch, metering switch, ISO button, WB button, Function button, AF/AE lock button, display button, delete button, live/lcd button, intelligent auto button, and video recording button.
As a result, control and handling is significantly better and faster than many entry level cameras where you need to dwell deep in the menu to change setting that you want.
IMAGE QUALITY
Image quality in low ISO setting is excellent. However, like all four thirds system camera, image in high ISO is not as good as regular DSLR camera that has APS-C sensor.
Image quality from ISO 100 to 800 is excellent. in ISO 1600, image starts to lose some details, sharpness and a bit of saturation. In ISO 3200, image starts to breakdown and 6400 is reserved only in emergency situation.
AUTO FOCUS PERFORMANCE
G2 is an very responsive camera. It shines in auto focus performance. AF speed is almost instantaneous whether in bright light or low light condition, I feel it can beat some beginner DSLR cameras. In G2, you can also touch the screen to set up AF point which is very convenient.
Auto focus tracking work well in slow moving subject, such as people walking, however, sometimes, it failed to track, especially fast or erratic movement. This is where the area G2 lacks compared to regular DSLR camera.
There are plenty to like about Panasonic G2
+ Small and lightweight relative to DSLR camera
+ Built-in high-res electronic viewfinder
+ Touch screen that allow you to change setting, set AF and flip image in playback
+ Swivel LCD screen help to compose photos in awkward angle
+ Fast Auto focus performance
+ Many dedicated buttons and switches
+ What you see is what you get (changing color balance, film mode shown in LCD)
+ Very good performance (responsive)
What I don't like about Panasonic G2
- Auto focus tracking is not reliable
- Image quality in ISO 1600 and above is not as good as regular DSLR
- Harder to achieve shallow depth of field (Defocus background)
- 1/2 to 1 second screen freeze after capturing photo
- Auto ISO is not very accurate and tend to stick with ISO 400
COMPETITORS
Samsung NX10 - Digital camera - prosumer - 14.6 Mpix - body only - supported memory: SD, SDHC - noble black
NX10 has bigger image sensor (APS-C) and higher-res (610k) AMOLED screen, however NX10 built-in viewfinder, body handling is not as good as Panasonic G2. G2 also slightly faster in auto focus performance.
Olympus PEN E-P2 12.3 MP Micro Four Thirds Interchangeable Lens Digital Camera with 14-42mm f/3.5-5.6 Zuiko Digital Zoom Lens and Electronic View Finder
Olympus E-P2 has a smaller design and more appropriate to be compared with Panasonic GF1 instead of G2. The main advantage E-P2 has is it has built-in image stabilization, however, it falls short in many areas such as slow auto focus especially in low light condition, low res LCD screen, and no built-in flash.
CONCLUSION
Panasonic G2 is the best flagship micro four thirds camera in 2010 with many new innovative technology such as touch screen LCD and full HD video recording. It is fun to use and carry around. However, G2 still has the same problem that has plague many four third system cameras which is image quality in high ISO setting. Despite it offers up to ISO 6400, but I recommend user to stick with ISO 800 or lower.
Subjective rating relative to mirrorless camera system 2010
Image Quality : 4/5 (with 14-42mm kit lens)
Features: 5/5
Performance: 5/5
Body / Handling: 5/5
Value for money: 3/5

Well, nobody is perfect. This samsung S5230 is not perfect either, has very well touch monitor (not sensitive); The body is light, good small size, good reception, good sound, good display, ok photo, allow MicroSD with a good size of memory, quad band and unlocked, well structured display interface and button placements, very responsive lock button, etc. etc... The battery life is terrible, between 24-30 hours with very light use, i.e. 3-4 calls a day of 2-5 minutes/each. However, with the price of $130s, compared to LG Vue, or even iPhone... I think I can live with that (I have iPod touch that is pretty similar to the iPhone, just w/o 3G, GPS and GSM capability). Not recommended for those who are traveling a lot, but good for those who stay stationary a lot The features are awesome.
