Error "camera module is not ready" or "Camera module not ready"

The error "Camera module is not ready" may be due to several reasons:

• Perhaps you've formatted the phone card or deleting things you should not, and "hangs" because the camera can not find some necessary folders.
• The mobile phone is poor (as UTStarcom, Sigmatel s3, n95, ZTC T88) using some of its many brands. They are generally very poor quality.
• There is a problem with the battery that provides little energy. It may be that the battery last long without downloading, but provide little Amps due to the poor quality of the battery.
• Also when recharging half (eg a hurry and desenchufas mobile without being charged at all) sometimes causes problems with the battery.
• The battery is Li-Ion (like almost all) and is coming to an end lifecycle (no matter if you use more or less, the Ion-Li "break" at 2 or 3 years to begin to be used.
• Has been damaged part of your mobile phone circuit, which is responsible for processing the data from the camera.
• It has damaged the chip that collects images.
• The camera has been moved or makes poor contact.

SOLUTIONS
In some phone models, sometimes the camera does not make good contact (eg due to a stroke) and leaves the place. Try removing the mobile phone and the camera move a little (carefully). Most often returns to work well.
If still not working:
Follow these steps:

1. Turn off the phone.
2. Remove the battery to the phone.
3. Connect the charger to the phone (without battery).
4. Connect the charger to the socket 220 / 110V.
5. Try turning it on and see if the camera works. If it does not light, turn to step 7.
6. Turn off the phone again.
7. Unplug the charger.
8. Put the battery in the phone.
9. Connect the charger to the phone (with battery).
10. Connect the charger to the socket 220 / 110V.
11. Charge your phone to the maximum.
12. When finished loading to maximum, turn on the phone and try to use it.

With this we have restarted the whole issue of voltages and currents as far as possible.
And now the final part:

1. Type the following: * # #
2. Now you're in the ("factory mode") "factory mode".
3. Now click "Select sensor type" ("select type sensor").
4. Choose the "gekewei" option and then "ok".

If still not working:

• Try a new battery (or a mobile phone of the same model, maybe someone you know can give you the awhile.
• If this does not work, the problem is certainly serious and should be on the integrated circuit. And that should fix a technician for repairing phones.
