Is there an Ubuntu Touch Full Screen function similar to Ubuntu Desktop's F11 function? If not, would it be possible to have one? This would be particularly useful on the web browser when holding the phone in landscape position.

@kugiigi You are right. Thanks.

Whenever I rotate my Nexus 7 in landscape mode, I get a split screen instead of a full screen when using the web browser. Could anyone tell me how to get rid of this split?

@AlainW94 Yes I do have a /data/calibration/mac_addr file. It contains the same MAC address as the one displayed on Settings -> About.

Regarding the syslog file, here is the output for a search of @@@@:

cat /var/log/syslog | grep @@@@

@AlainW94 Here are some errors found in /var/log/syslog:

@AlainW94 I tried again and I got the following output for syslog:

cat /var/log/syslog | grep wl0
Mar  7 14:44:23 ubuntu-phablet kernel: [    8.877130]  [6: NetworkManager: 3204] [c6] Firmware version = wl0: Nov 24 2015 11:23:00 version 7.45.71.r5 (r587357) FWID 01-ec3fd0c

@AlainW94 "cat /var/log/syslog | grep wl0" gives no output at all.

@AlainW94 from the beginning.

@AlainW94 I haven't tried to re-install Android and I am a bit reluctant to do so unless I have some evidence that this is the way to solve the password issue. I haven't tried the WiFi on Android. I replaced the factory OS with UT as soon as I got the phone. I have no reason to think that there was any WiFi problem with the factory settings. I don't know what WiFi "log files" are nor where to find them. I also don't know what WiFi band my phone is using.

The problem is that I am still in the dark as to whether the EFS partition is the issue or not.

When you wipe or format with TWRP, there are some options to choose what to wipe and what to keep. Could it be that those of us who wiped everything loose the WiFi password while those who didn't have no such loss?

I also don't know if re-installing Android would restore the EFS partition or not.

Yes @matteo I would prefer ATU to be on the Open Store. I haven't installed it. I would prefer to install lshw and hwinfo directly with apt-get install or dpkg -i. But there are some dependencies. I know we are not supposed to use these Ubuntu Desktop tools on Ubuntu Touch. However I have managed to install htop with apt-get without much trouble. There is now an app in the Open Store for htop but it may just install htop with one of these Ubuntu Desktop tools, I don't know.

@Stefano I also have a Nexus 7 (2013) and I couldn't get UT to boot properly until I replaced the version of Android I had with an older version of Android. I have no issue with the WiFi password on this tablet. The nexus 7 works remarkably well with UT.

@matteo what is this software called "ATU"? Where did you get it from?

@UniSuperBox Thank you. Actually, I don't know if the WiFi is working correctly with Android. I removed Android and installed Ubuntu Touch as soon as I got the device. I haven't tested the password issue with Android.

Do you mean the EFS partition is custom to the serial number of the phone or custom to the Pro 5 in general (identical to all Pro 5s)?

I could check what hardware I have in my Pro 5 if only I knew how to install lshw or hwinfo. I am a bit worried about installing anything with apt-get. I once installed a package with apt-get and the phone wouldn't boot afterwards. I had to reinstall the whole Ubuntu Touch OS. Should I use a Libertine container to install such a small package as lshw or hwinfo?

Thank you @Stefano. I suppose this implies that the Flyme OS image includes the EFS partition, doesn't it?

A temporary or permanent fix could be to add a command line to the .profile or .bashrc file. The WiFi password could be automatically re-written by this command line at boot time. But I don't know what file the WiFi password gets written to nor if it has to be encrypted like the login password in /etc/shadow. Does anyone know?

No one has said if it is possible to install the Ubuntu Desktop packages $ lshw (list hardware) or $ hwinfo (hardware info) on Ubuntu Touch. This could tell us if there is any variation at the hardware level between MEIZU phones with the WiFi password issue and those same phones without this issue.

I followed this excellent guide when re-partitioning before installing Ubuntu Touch 16.04:
https://wiki.ubuntuusers.de/Howto/Installation_Ubuntu_Touch_auf_MEIZU_PRO_5/

All went well except that I had this error message:
Note: sector size is 4096 (not 512)
Found valid GPT with protective MBR; using GPT

and then this message as well:
GPT PMBR size mismatch (15267840 != 15267839) will be corrected by w(rite).

I have no idea if this is relevant or not.

@Stefano You said you had 3 different Pro 5. Did anyone of them had 4GB of RAM?

@UniSuperBox
Thanks, you must be right: the Wi-Fi MAC address changes after reboot. The bluetooth MAC address and the IMEI do not change.

I am surprised that the Wi-Fi MAC address changes because I thought the MAC address was some sort of serial number somehow electronically "etched" on the Wi-Fi chip inside a read-only memory that could not be overwritten.

Does EFS mean Encrypting File System? Such a system is said to exist on MS Windows systems only.

I don't know if I have an Exynos or a Qualcomm device. Is it possible to install a command like $ lshw or $ hwinfo to list all the hardware inside the phone?

Anyway, I don't think I have a backup of EFS, whatever this partition is.
