Problems with Huawei Devices #398

Closed corbinlc closed 5 years ago

corbinlc commented 5 years ago

Describe the bug:

This issue is to summarize remaining issues related to Huawei devices. The more recent Huawei devices don't support PRoot doing POKE_DATA on the tracee. There is an expensive and ugly workaround in place, that mostly works, but looks like it still isn't perfect. There are two problems, some things still don't work on Huawei devices, mainly things related to using VNC and GUI based apps, and performance is noticeably impacted on these Huawei devices.

I am going to be adding more details to this and pointing some existing issues at this, so we can track this problem and the related work in one place.

I am starting this to satisfy the desire described in #391 in a different way.

corbinlc commented 5 years ago

Can people chime in with the specific issues they are having (including step to reproduce), what Huawei device they have and what version of Android it is running?

saurabh6377 commented 5 years ago

I think the main problem is android O, userland is broken for android O, there is problem connecting with GUI application like vnc and there is also problem connecting with SSH server It always shows host has disconnected after doing "apt-get update" and "apt-get upgrade" as I mentioned in #401 I am not sure if this problem is Huawei device specific only as I am also using Honor 9 lite with Android 8.0.0 stock ROM. I will update this later by installing custom Oreo ROM on Honor 9 lite and testing userland.

Update: I just saw #380 and #364 and I am sure these are the same issues I encounter every time of doing fresh userland install from PlayStore then I clear data then everything works fine then after doing everything (updating and upgrading) the terminal hangs while installing any big packages (like xfce4, libreoffice, firefox, lxde) even after 6-7 hours installation won't complete (which completes in about in 30 min in my old android N phone) then I kill service in userland then start again everything and run "dpkg --configure -a" package installation resumes and hangs again after some time then I repeat the above process then it hangs once again after that userland won't connect to any SSH or vnc server and I encounter error everytime (SSH server I am using - Connect BOT and vnc - bVNC) I will take proot debug log then report the issue later as I am out of time now. Userland version 1.0.0 Android version 8.0.0

I have read one information here, that Huawei is suffering because of wrongimplementation of one Android Kernel procedure or service I Am not kernel expert, Pokedata. I recommend The most advanced developer here if he could get in touch with Huawei company. The main problem is, that if this Kernel function or procedure Pokedata is not implemented well for Proot, that other phone functions are working perfectly,since I have Huawei with ANdroid 8.1 at home with update from 10 month of this year. Phone is stable, even intensive use of text to speech engines is working. Modern Huawei devices have very advanced power managementcontrols,but default setup is not set to extra suspended battery mode. I think that MR Chanpion and other Proot developers for Userland could try to discusswith Huawei developers. I AM afraid, that Pokedata have been implemented with The intention to disable users of Proot module to use it for advanced tasks, may be, that wrong implementation of this kernel procedure have been The intention of Huawei company.

I have a huawei p10 plus, vky-L09, running android 8.0.0 I can set up a debian filesystem but cannot get r to run. Also see https://github.com/CypherpunkArmory/UserLAnd/issues/405

projectextremum commented 5 years ago

In that case, rooting the phone may be the only solution. What about termux? Probably they provide a native R package. GUI is mostly DIY but it works.

Yesterday, I managed to put xfce4 on an Honor 5C with AnLinux, Termux and bVNC (yes, bVNC). See enclosed screenshot. Because I think that my problem with UserLAnd might be with memory (issue # 423) and lxde which might be bigger, despite the "light" in the name, I'm going to uninstall UserLAnd and bVNC this morning, then reinstall with xfce4 and see what happens. The bottom line is that I would much prefer to use UserLAnd ! screenshot_20181127-175250

JanuszChmiel commented 5 years ago

I have informed Huawei company by using their Facebook WEB page, chat function. May be, that they have only answered Me because of politeness that they have sent my info related to Pokedata Kernel function to The competent team. May be, that developers will not modify their kernel variant, because their Pokedata variant do not cause instability of other standard phone functions. We have to wait for AN surprice.

AuntieE commented 5 years ago

I have since put xfce4 on my HONOR 5C telephone with UserLAnd and bVNC. It seems that it IS a memory problem. screenshot_20181128-114128 screenshot_20181128-114156 I am THRILLED 👍

Hmmm I don't think so. The affected users are using emui 8 (oreo) whereas you are using emui 5 (nougat). Furthermore, higher end models (as compared to your midrange honor 5c) are also affected by this... :(

So it's probably a bug with emui 8

corbinlc commented 5 years ago

378 is also a Huawei device problem

corbinlc commented 5 years ago

One of the things that Huawei does differently that will impact many users is it aggressively kills background apps. This article talks about how VLC Media Player had a similar issue and how you can tweak some settings to help. https://lifehacker.com/how-to-use-the-blacklisted-vlc-app-on-your-huawei-smart-1827898672

I have not tried those changes myself, but we have run into one other scenario where changing such settings helped a Huawei user.

corbinlc commented 5 years ago

Looking at the issue of running graphical programs on Huawei devices again, I do see one issue in a proot log that I just created. I have no idea how quickly that will lead to a solution, but at least there is a symptom I can look into.

Kymonlucky commented 5 years ago

@corbinlc is there any update about "!IS_IN_SYSENTER(tracee)" issue? . Thanks!

ghost commented 5 years ago

This appears to be fixed in emui 9 as I am able to run xfce after updating to emui 9 from 8.

corbinlc commented 5 years ago

This is great news. I hope all the effected devices get EMUI 9 soon. They were all fairly recent devices, so I hope so. Thanks for the update. I will check whether our Huawei device has an update pending.

corbinlc commented 5 years ago

Can people tell me when they are able to get EMUI 9 and also tell me what device they have and whether the update solves issues seen before? I want to gauge how quickly this is resolved by Huawei, to better determine how much more effort I should put into it.

mscion commented 5 years ago

Hi. I've had it running on my Huawei Mate 20 Pro for a day or so now. Seems to connect ok now. I have a couple other Huawei phones I'll try it on and get back to you.

Works on Huawei Mate 20 X. Pretty much same innards.

Am checking Mate 10

mscion commented 5 years ago

Also seems to work ok on Huawei Mate 10. For my 3 Huawei phones I loaded Debian, libreoffice, wxmaxima, and xfce. Thanks!

corbinlc commented 5 years ago

We are no longer hearing any issues as most people have been able to move forward to EMUI 9 and no longer have this issue. As such, I am closing this. Please file new specific issues for any remaining problems.

I had the same response at starting Ubuntu at OUKITEL_C35_EEA_V11_17122023, Android 13 as on #505 by Kymonlucky. I could start Alpine and Debian. I am very much beginner for Android, I just lose just only two days with your info. I understood this could be fatal issue at the note here, so I decided to use Debian. Thank you for your info.
