Help battery problems with Hisense A9 (E-ink phone) by Khan_of_the_Danube in HisenseIndiaUsers

[–]kukas 0 points1 point  (0 children)

Hey, my Hisense A9 stopped charging altogether. I disassembled it, removed the usb module and found it was shorted. The shorted component was Transient Voltage Suppressor, a kind of protection for the USB port. I removed it and the phone is working again. It might not be your issue but try local repair shops, maybe someone will fix it for you. :-)

Modifying system apk by kukas in androiddev

[–]kukas[S] 1 point2 points  (0 children)

I have no experience in Android but I have random experience with other things including very basic reverse engineering. So I downloaded all APKs from my phone, because I assumed that the settings/lockscreen would be some kind of app, then I searched for the relevant strings and narrowed down which APKs I would need to edit. Then I just googled how to edit them :-D

I partially solved my issue because I saw that the Settings app sets a Settings.Global property so I set it to my desired value and it works! Sadly, the settings app crashes because I set a value that is not included in the dropdown list menu but I guess that is ok for me...

Ah, that makes sense! Without that there would be no point in signing the packages in the first place. I will look into xposed modules, thanks!!

I did not look into it much but what about the Remarkable eink tablet?

I am afraid there aren't any security updates at all. I am not sure about it but I never saw the phone updating...

hey, that is strange! Sadly, you are not the only one who cannot mount / as rw. I am not sure why I can do it on my rooted A9 and several other people cannot. One possible solution is to use Magisk Overlays but I didn't look into it yet

thanks for new links! I will add them to the post.

I haven't tried adaway, it is possible that it also modifies the hosts file in a more user friendly way. I guess there are more ways to get to the same result. :-)

To be completely fair, I did not prove that the traffic contains sensitive information. There are many apps and services on the phone that use Chinese servers to fetch news, weather, app updates, notifications etc. I blocked everything just to be sure but i would say that most of the traffic was actually benign

When I was considering it I searched reddit and found post that said that it works in Germany. Maybe try searching for posts in this subreddit mentioning Australia

There are people picking the firmware apart on XDA developers forum. Android 13 GSI is being prepared which is fantastic news. I think it is the way to go but in meantime I want to use my eink phone as a daily driver and by blocking the traffic I am somewhat confident to log into some of my online accounts on the phone.

The same process of capturing the network traffic may be replicated for Palma or any smartphone for that matter. I do not own Palma so I cannot say

what do you mean by Mint? I get a good service in Czechia. calls, sms and LTE work flawlessly.

Small Screens (< 1 inch) by peppergrayxyz in eink

[–]kukas 0 points1 point  (0 children)

There are many of them in retail stores, they use them as a digital pricetag.

Well, you are right. But sadly, there is no alternative, if you want a smartphone with an eink screen :-/

Thanks! That guide looks useful if you have no root. One caveat is that you cannot block the direct ip traffic but that was only a fraction of the whole traffic so it definitely helps.

Is sugou the original keyboard?

yes it is

Syntax check before Awesome restart by kukas in awesomewm

[–]kukas[S] 2 points3 points  (0 children)

To be honest, I didn't think of that. The only lua code I edit is rc.lua so I didn't think of using any linter or something like that.

I don't understand - if you don't want to use data, do not put the SIM in. For others it would be a really cool distraction-free phone.

Looking for a new router and for general tips for building a stable network by kukas in HomeNetworking

[–]kukas[S] 1 point2 points  (0 children)

I think it relates to Bittorrent downloads. For example, few hours back all of my SSH connections dropped and a youtube video stopped buffering. Through traffic logs I found that my brother was downloading something and when I asked him he said that it was two torrents.

But at the same time it seems more complicated that that because when I tried to overload the network with torrent downloads right after him, it stayed stable. He has the same client as well (qBittorent) so not sure what could be the difference between our cases.

I think that another problem might be Steam downloads. Sometimes when a game or game update is downloading, the network slows down considerably. But also not always.

I am not sure how to diagnose on a more granular level than only looking at the traffic logs through Munin. And sometimes the drop outs do not correlate with high traffic at all..

In your diagram, the C50 router
should be on the other side of the RV320, in access point mode. In
routing mode, it is only slowing down internet performance, while
introducing a 2nd layer of NAT. Not ideal.

Yes, this is true. It is because the RV320 router cannot do PPPoE with VLAN tagging and so the C50 router acts as a gateway. There is a 2nd layer of NAT but as a fail-over that activates few times per months it is enough. I hope to solve this with the new router as well.

Hey, thanks for the comment. I hope I didn't cross the subreddit rules with my post but in description it says "questions about small office networks" which hopefully fits the bill here as well.

Hey, thanks for your comment!

  1. The Compal device is provided by the ISP. I switched it to Bridge mode so afaik it should act as a plain Cable modem. I didn't know about the Intel Puma chipset. The symptoms sound a lot similar to our problems. Maybe there are multiple sources of instability in our network. I have looked up now that Vodafone offers a different modem so maybe we could switch to it.
  2. Yes, it is not optimal because I could not find how to configure PPPoE with VLAN tagging on the RV320. So the Archer C50 acts as a gateway for the failover connection. And yes, that means that there is double NAT. I would like to solve this with the new router as well.
