N okia today announced three new Symbian^3 smartphones at its Nokia World event: Nokia E7, Nokia C7 and Nokia C6. These three share the OS with the upcoming Nokia N8, which (according to Nokia) is the only N-series device which will be based on Symbian^3.
The E7 is a device aimed at business users, with a full QWERTY keyboard, a 4-inch, 640×460 pixel touchscreen with Nokia’s ClearBlack technology for improved outdoor visibility and an 8-megapixel camera capable of recording 720p video. It touts 16GB of storage memory, and 350 MB of internal memory. In accordance with its business pedigree, the E7 can create PowerPoint slides on the go. It comes with a price tag of €495 ($638).
Nokia C6 has a 3.2-inch AMOLED screen (also with ClearBlack technology), while the C7 has a 3.5-inch AMOLED screen and a case consisting of stainless steel and glass. Both devices have an 8 megapixel camera with dual LED flash and the ability to record 720p video.
Nokia C6 has 340 MB of internal user memory, while Nokia C7 has up to 350 MB of internal memory and 8 GB of storage memory. The memory in both devices can be expanded with a 32 GB microSD memory card, and the price is €260 ($334) for the C6, and €335 ($430) for the C7. All three devices should become available before the end of 2010.

From screen separation to USB charging issues, here are the EVO 4G pitfalls users complain about most.

Poor battery life

Sure, your shiny new EVO 4G will function as a Wi-Fi hotspot, sharing out your 4G signal to up to eight friends, but you had better find an outlet if you want to keep them happy. Although the EVO 4G has roughly the same battery capacity as most other smartphones, heavy 4G use can quickly whittle it down within just hours. It’s not a manufacturing error: Just an unfortunate consequence of pumping data way faster than your 3G peers.

USB charging issues

A small number of EVO 4G buyers report they have had issues charging their phones via the microUSB port. Some claim their phones will not charge at all, while others experience intermittent charging. The problem appears to be due to the female microUSB port working its way loose from the motherboard. HTC is aware of the problem and will exchange phones within the standard one-year warranty period.

Light leakage and glass separation

The 4.3-inch display on the EVO 4G, gorgeous as it is, has had some issues. Early adopters complained that the screens on some phones are not properly sealed, leading to light from the backlight bleeding out, and potentially in the long term, dust build up. HTC claims it has remedied issues at the factory that caused the problem.

Unresponsive touch screens

The EVO 4G uses the same capacitive technology found on devices like the iPhone and Droid, but some users complain the device can become unresponsive when it isn’t grounded (being held in the hand). Check out the demo video below.
