1) Battery life: even for an Android, the battery life is REALLY low, but in many cases it became longer with the use of the device. Many people tried to remove the skin case and noticed a significant improvement: they said that the case was too tight and continuously pressed a button that kept the display turned on, therefore consuming energy.
2) Display: it has a flickering problem, in some cases this problem is unnoticeable, in other cases it's very annoying. Someone said that it's a sort of interference due to 2G connection, but in the end it's not sure if it's an hardware or a software problem.
3) Firmware: Samsung released a new firmware to improve battery life, but this upgrade brought further problems: it causes casual reboots, mysterious disappearing of some market apps, and often doesn't prolong very much battery life.
So, i hope that the galaxys that you will get in england will have those problems fixed. I also hope we'll get a new firmware soon...
Can you please tell in this thread if your galaxys present those problems? Every i7500 user would be grateful knowing that you haven't got any malfunction.
Sorry for my poor english and good surfing!
