Hi, I just wanted to let you know that I was able to solve the problem.
I followed the instructions found in the fairphone forum of others who had the same problem.
I disassembled the fairphone and unscrewed the camera module.
I cleaned the contacts with a cotton bud soaked in alcohol.
Reassembled everything, the camera app works great since yesterday.
I hope it keeps working.:cat_face_with_wry_smile:

Hello, I have solved because the connection problems did not come from the smartphone but from the operator.
A website that monitors the performance of operators on the internet confirmed what I said.

Hello,
Since yesterday the internet connection, despite being started the procedure for recovery in a correct way, can not stay and the phone does not connect.
Is there a proper procedure to solve the problem?

Hello, thank you for your comments but, in fact, you have not answered my simple question: how can I reinstall Ubuntu Touch?
I know Ubuntu, the big brother for desktop, and then I would know how to do it.
But in the case of Ubuntu Touch I am ignorant in the matter.
What can I do about it?

I installed Ubuntu Touch on the Samsung S3 Neo but something doesn’t work: at the beginning it remained the Samsung logo and the camera app only works the selfie.
How can I reinstall the operating system?

Hi, I’m asking if there’s a possibility of installing a screen saver from our operating system.
By the way.
I have installed Ubuntu Touch for 3 days and everything works perfectly.
I like it: very fluid and easy to learn.
I’m so glad I finally quit Google.

Hello, I successfully installed Ubuntu Touch via installer with an Ubuntu Mate OS pc.
The only problem remains the camera that does not work or at least vertical striations of each color appear and the image does not appear.
Do you have any ideas to solve the problem?
Did someone have the same problem?
Thank you in advance.:cat_face:
