IMPORTANT NOTE!

INSURANCE FOR YOUR PHONE! As you know, the insurance companies and some mobile phones store offer insurance for your phone. So for a small monthly fee, your phone gets premium insurance policy, that will fix whatever warranty can't fix. Even in case of burglary your phone will get replaced with a new one. So, you accidentally break your screen, insurance will cover it, break the USB port, insurance will cover it, the GSM is no longer working, insurance will cover it.

Here is Orange insurance for my country: ORANGE INSURANCE

You can search on google your local stores/insurance companies that offer services in your area, and for a small fee (in my case 3 euros/month for a 250 euros smartphone device).

BUT BE CAREFUL AND READ THE CONTRACT FIRST WITH MAXIMUM ATTENTION. NOT ALL INSURANCE COMPANIES COVERS EXACTLY WHAT I SAID!

1. Introduction

What to check before buying a new Nokia N900 handheld device:

Major scratches on the screen

If the slider is okay (not too lose)

Bluetooth and Wi-Fi capability

IR Port capability

Accelerometer functioning properly

Camera flash

Light sensor and proximity sensor

Open terminal and type "cat /proc/cpuinfo" and check revision ( since 2101 and 2104 are factory faulty - not all of them so you need to check the following 2 steps if the revision version is 2101 and 2104)

MicroUSB port (check for it not to be loose and work properly)

GSM Driver (by applying pressure in corners or keyboard and see if the GSM signals fail - the "E" key is close to the chip, check that zone first)

KNOWN BUGS/WARANTY PROBLEMS RELATED TO N900 DEVICES:

Nokia often offers new N8 or E7 devices as warranty replacements for N900s. Although warranty terms and consumer rights legislation differ across jurisdictions, users have reported success in refusing those and pressing for an N900 in at least the EU and India as recently as August 2011. Owners who are not confident of getting an N900 as a warranty replacement often attempt to repair their own devices, or sell the Nokia-provided replacement to buy an N900 instead.

The N900's proximity sensor, which is designed to lock the touch screen when the phone is against the user's ear to prevent accidental operation, locks the screen unintentionally in bright light (usually outdoors) when a call is placed or received. Nokia has acknowledged that it is a "hardware issue" and cannot be addressed. To unlock the screen in a phone call, a tactile unlock switch in the right side of the device can be used. This however will keep the touch screen active and accidental operation of the phone keys in a call may occur when device is used as a handset. This issue has been blamed on the application of screen protectors, however N900 users without screen protectors are also experiencing the problem.

Also the N900's MicroUSB (charger) port is very fragile. Some people have successfully fixed this problem with either epoxy glue or soldering the USB port down on the motherboard.

Also the SIM-card reader might be badly soldered to the board. Multiple N900 devices are troubled by the problem that the SIM-card cannot be detected anymore. Users may be able to fix this by putting something between the GSM related chips and their cover.
