There are a number of threads about the loss of WiFi password after reboot of the Nexus 5 and of the BQ M10 but not much about the same problem on the MEIZU Pro 5 apart from https://forums.ubports.com/topic/708/meizu-pro5-fastboot-mode-locked

I have a MEIZU Pro 5 with 4GB of RAM and Ubuntu Touch 16.04 UBports OTA-7. This is not the Ubuntu Touch edition. This phone came with Flyme OS and I installed Ubuntu on it. I need to re-enter the WiFi password after reboot.

The way this problem occurs is strange because the password is not completely lost. If I open the Settings, go to Wi-Fi and then to the list of Previous networks, my access point is still there and it does have the password. The problem is that when I select this access point in this list, the only option I have is to Forget this network. I can't enable the connection from the list of previous networks.

In order to connect to this access point, I have to select it from the current list of networks from which the password is lost. Once I enter again the password, the list of Previous networks creates a new entry with the same network name albeit with the suffix " 1" added to it. If I reboot again and do the same thing, a new entry appears once again, this time with the suffix " 2". And so on with the suffixes 3, 4, 5, etc...

Has anyone found out how to fix the problem since the thread mentioned above?

Two questions if I may ask:

1 - How would it be possible to lower the minimum screen brightness?

2 - Would it be possible to have a full-screen function like the F11 function there is on Ubuntu Desktop? This would allow to display more lines to read on the web browser by hiding the web page address at the top of the screen. This would be particularly handsome in landscape mode.

I lower the display brightness to its minimum when in the dark but I find this minimum a bit too high. In the dark, the brightness is a bit blinding. How would it be possible to alter this minimum?

All Ubuntu Touch apps store user data in ~/.local/share/app-name/. It is impossible to open a file stored for instance in ~/Documents/.

One way around this would be to create a symbolic link:

 $ ln -s ~/Document/data-file ~/.local/share/app-name/link-to-data-file

Unfortunately, opening such a link with an app yield an empty file. However, if the data file were in the same directory as the link, then opening the link would yield the full non empty file. That is, if the link is created as:

 $ ln -s ~/.local/share/app-name/data-file ~/.local/share/app-name/link-to-data-file

then everything works fine.

It seems that Ubuntu Touch apps are blind to the directory tree. Does anybody know a way around this problem? How could one choose where to store data files and not be restricted to ~/.local/share/app-name/ ?

Shall we ever be able to boot from a mainline kernel and from an SD card on Android devices?

@hankschwie

UT Tweak Tool themes have no effect on the brightness of apps.

@kugiigi You are right. Thanks.

Usually recent mobile phones don't run UT because it takes time to port the software onto them. So I am surprised that the port to the OnePlus 6T was so quick. What happened then?
Has anyone tested convergence on this beast of 8GB of RAM? This could be an ideal device for use as a desktop computer.

@BrisPete Thanks BrisPete. I should have found out by myself instead of starting a new thread... Sorry.

@3t_ed Yes I have experienced issues with the keyboard too.

I can't install Ubuntu Touch on my OP6T. The installer is stuck at

"Waiting for device... Fastboot is scanning for devices".

This happened after the phone became bricked as it booted and still boots with the following message:

QUALCOM CrashDump Mode
Attempted to kill init! exitcode=0x0000000b
complete_and_exit

I bricked the device after running into difficulty trying to install TWRP first:

fastboot flash recovery twrp.img
Writing 'recovery' FAILED (remote: '(recovery_b) No such partition')

Then I read https://android.stackexchange.com/questions/209673/why-cant-i-write-to-recovery-using-fastboot-on-a-b-device which advised to run instead

fastboot boot twrp.img

That is when the phone became bricked...

May I ask if Focal Fossa is working on the Meizu Pro 5? If so, should I upgrade to it or should I stay with Xenial?

@arubislander Just to clarify:

• I don't run any server. I have no network at home apart from the link between my router and my PC and UT phone. The server I was referring to belongs to the commercial email service provider and may be located in another country.
• I am not absolutely sure that the issue does not appear on my PC. It just happens that I have noticed it on my UT phone. But I think it does not happen on my PC.
• I am using µAdBlock. But is this a problem?

@arubislander Thank you arubislander and AppLee. The cracked padlock in red does not always appear like this. Most of the time it appears as a normal locked padlock in black. Here I am talking only about a single website. On my PC with Firefox under Linux, this web site appears with a normal padlock. This web site is my web mail for which I am paying a fee every year. So it is quite a serious breach of security. Could this be a hack directed against the web mail server or even a hack against my home devices?

When I visit a secure (HTTPS) website, the usual padlock in the address bar of the Morph browser sometimes appears as red and cracked. I suppose this means the connection is not secure. May I ask why and how this happens and how to avoid it?

I have lost the four digit password which must be entered after booting. This is on an old device which I haven't used for ages. It does not have any particular data that I would want to keep. So I could erase everything and reinstall the system altogether.
However I suppose I need to enable adb access before reinstalling, but I can't because I don't have the password.
So what else could I do please?

@josele13 Reinstalling Ubuntu Touch won't bring back the EFS partition which is a firmware from the manufacturer.

@josele13 Yes thanks. I had actually already tried this to no avail.

@arubislander I am on the stable channel with OTA-23. I fear that the problem has the same root as the one described in this old post of mine where it has been suggested that I might have deleted the EFS partition when I repartitioned the phone before installation. I had to repartition because I have the non-ubuntu edition of the Meizu Pro 5 with 4GB of RAM instead of 3GB.

@arubislander I have tried the WiFi scanner from the app store. It shows the name of the hotspot with the hexadecimal code in the format [XX:XX:XX:XX:XX:XX]. But the hotspot name is nowhere to be found on the list of WiFi access points on my PC.
