[ROM][UNOFFICIAL][7.1.2] LineageOS 14.1 [trlte][trlteduos]

[teegale]

Can this fix also be applied to trltevzw kernel? Or is it specific to trltetmo?

Try this data drop test, install Google duo app from play store and make few calls, as you're calling, swipe down the notification drawer and keep an eye on your carrier signal.

Just tried that. Data didn't drop. Stayed the same the whole time it was calling.

This fix is specific to trltetmo, not trltevzw, but from what I can tell going through the thread, trltetmo has the worst data drops and both trltespr and trltevzw not so much...?

Yes, that is the case. Verizon drops intermittently but when you need the data at the critical moment it drops. Such as forum post, or video call, data drops. I'll have to flash the mentioned 10/22 build and try it out tonight.

 

[GerardSamija]

Speaking of more than one build in a single day, I merged this quick fix into my fork of the new kernel and I'm building a 2nd trltetmo build that could potentially not have data drops. Check the folder in about an hour and a half.

lineage-14.1-20171023_162147-UNOFFICIAL-trltetmo.zip(data drop fix)

The filename took me a moment to figure out... just have to rename it with .zip being the end. Silly me.

Dirty flashed, wiped caches. Checking connection with email (Kaitenmail), FTP Cafe Pro, and Dolphin (visiting a few sites where typically images lower on the page don't load with a flakey connection in effect) and so far it's all brilliant! Absolutely no delays, flawless. I'll observe over the rest of the day and report back if necessary, otherwise report back tonight if there have been no problems. I haven't seen quite this fast and solid an initial data connection with any build since August.

 

[teegale]

Anyway to make the apps in the recent tab smaller sized? Or would that relate to dpi?

 

[GerardSamija]

Data dropped while I was talking with a violinist... I just checked the phone again and found email there I'd deleted on the PC at least 15 minutes earlier - with Kaitenmail polling every 5 minutes that makes the data disconnection at least 10, maybe 15 minutes old. Toggled the connection and it reconnected in a few seconds and auto-deleted those messages. Seems the data fix isn't as perfect as my initial testing showed. Still, once reconnected it stayed solid for maybe 10 minutes. Then dropped again when I looked away from the screen for half a minute, the icon with the x in the corner then reconnecting in a few seconds while I watched. No new demand on data (no Kaitenmail polling in the notification bar, and I know it had auto-polled a minute or so earlier) so not triggered by my doing anything. So perhaps a napping component involved? I've tried the odd data connection retention app back in September (several wipes and clean installs since then) but nothing really made a lot of difference.

is this tmo with the fixes? this morning I played tunein radio off mobile for an hour without any drops... normally it kills mobile after 1 second. same w/YouTube....

the symptom was that the mobile triangular icon would literally disappear and then return. hasn't don't that for me yet with the proposed fix...

Yes, sad to say, this is with lineage-14.1-20171023_162147-UNOFFICIAL-trltetmo.zip(data+drop+fix) flashed and caches wiped. Your experience with data drops seems from your description to have been worse than mine, or at least more consistent in the failures. I've often been able to stream with TuneIn Radio or YouTube (I use Dolphin-Browser for streaming video - can't STAND the YouTube app) for extended periods on cellular data. Got the CBC playing now on TuneIn. No disconnections after 10 minutes. But just before that I saw a string of disconnections which happened with only basic browsing and email, since my previous post.

Hmm sounds like we've been having different issues. My TMO phone would fully disconnect and reset the connection. The "x" almost immediately followed with the triangle icon completely disconnecting (the modem was apparently disconnecting from the underlying USB-like bus that it was attached to) and then reconnecting/initializing and the icon would reappear. But by then the streaming had already errored out so playing tunein or the youtube app would result in an error and nothing further would happen.

That behavior at least for me is gone now. The disconnections your'e describing-- to be clear-- is only the "x" over the connection but NOT the triangular icon disappearing? Does anything appear in the log? Do you notice that the signal drops only in certain areas? Also, to be paranoid, anything show up if you use something like snoopsnitch in case you happen to be near a Stingray or something...? Okay, that's a bit extreme but you never know...

Thanks to @fattire, I expanded the data drop fix to both trltespr and trltevzw in time for tomorrow's builds.

Even better, repopick this:

https://review.lineageos.org/#/c/194298/

This pulls the entire commit that my patch disables. Upstream qcom wasn't even including these changes for apq8084, so removing the whole commit shouldn't affect any of the devices except in a positive way. So if you repopick 194298 before building, let us know if it works

Ok then, I'll revert the current changes and merge this.

Sorry that I was unclear; yes, as I've reported quite a few times in this thread, some of my data drops include a complete darkening of the connectivity icon, going to just a dark grey triangle with black inside. Most are just the x in the lower corner. Some are also just a white triangle with no '3G' to be seen. If I've been less than forthcoming with data drop related verbiage, it's because of the mixed messages all along for the past two months. I was hounded by other users for mentioning data drops in early September, so I stopped posting here at all as a courtesy. Then ripee invited input on data drops... then not so much... then again... it's all a bit confusing. I understand that this problem is a 'known issue' for some variants, mine included (though I'm still confused there, as ripee calls my phone a 910T but Phone Info and Kernel Adiutor tell me it's a 900W8), and that no authoritative fix is yet announced. Last I heard officially it seems the problem itself hasn't been identified.

As for snoopstitch, I'm further confused. I followed your link, downloaded F-Droid, installed from the APK and launched, which promptly took me to the Play Store on the CY Security Antivirus Cleaner page, asking me to install that. So I guessed that this was part of what you're suggesting and installed that. Opening this new install took me to a window with 'Fdro...' in the upper left corner and some other tabs, showing me a message "All apps up to date. Congratulations! All of your apps are up to date (or your repositories are out of date)." Which makes my head spin a bit. Is F-Droid malware, doing something weird? I'm seeing no 'scan' option anywhere. There are tabs called Available, Installed (4), Updates (0), a search icon, a refresh icon, Swap Apps, then two menu icons. I've been about a second away from opening RevoUninstaller since installing this useless baggage... but have held off that impulse pending further input from you, as I really have no way of knowing what the heck this nonsense has to do with my connectivity issues.

As for things appearing in the log, I have submitted multiple logs earlier in the thread, both logcats and dmesg files. So far pretty much zero in the way of feedback on those, from ripee or _mone or anyone else, though they've been requested.

Also, as I've stated multiple times in this thread (and in a PM responding to a PM from ripee this morning) while there are known dead or weak zones for my provider in my city, my house has never been one of those. I work at home, getting out for maybe an hour a day most days, sometimes not at all. With my Note 3 the connection was always rock solid, first with a bigger cellular provider, then with the smaller Freedom Mobile (formerly Wind) which I have used for the past couple of years. 4 bars, period, day and night. Some of my clients also use Freedom Mobile and likewise never have a problem with connectivity on working phones. It's only with the Note 4 acquired in August, and only after jumping from 6.0.1 to 7.1.2, that I've been experiencing problems, and only in Lineage builds. No problem with RR or a couple of other ROMs I've tried - but there were sufficient other problems in various others such that I've come back to hoping Lineage would work out for data, as everything else usually works fine here.

Edit: I've run a scan with the CY Security app. It's claiming a 'Fraudulent SMS Vulnerability' and offering to repair it. Tapped 'Repair Now' and it says "Perfect" and "You phone is in peak condition!" Spelling error aside, that sounds like a good thing... tapping 'Finish' it says "Perfect Protected for 1 day" which isn't reassuring. I'm thinking that app is getting uninstalled. Last thing I want is another background service hogging resources. The Note 4's inherent laggy nature even under Lineage isn't ideal at the best of times. More services generally mean more lag.

I have no idea what the cy security app is. it sounds extremely sketchy. uninstall it, wipe, purge it. get rid of all traces of it

F-Droid is an alternate play store type of app market where every app is open source. snoopsnitch might also available on the play store. not sure. I only linked to the open source method of installing it (fdroid) for you to find more info and the source code, but you should use the play store of it's available there. no idea how you ended up looking at that "security app"unless maybe it was in a "people who installed x also installed y" list or something

snoopsnitch tries to identify if there are any fake cell towers around, such as stingrays, which if you were living near someone under surveillance might account for weird connectivity... it was just an offhand thought...

can you post new logs with this new kernel as of tomorrow build of the moment your mobile goes to the "x"? both logcat and dmesg again. hopefully you won't see the triangle mobile icon just disappear and this is more of a regular issue with the signal not being strong enough.. the log should help clarify now that the other issue is hopefully fixed.....

also since you have this unusual Canadian 900w8 you should look at the stock Android settings (build.prop, the files in /etc, and the init.rc files because there might be something set particularly with the radio that is different from a regular us tmo device.

also be sure to go to settings/wireless and network and reset the mobile settings and cellular network. I'm guessing there is some difference in the files you'll find in the independent device repositories (900t, 900f, etc) that's where id look.

typing this in my phone. took forever sorry for typos... heh

I will make time to grab and share logs of both types after the next nightly. Not sure about timing, as it's really hard to guess when the connection might cut out. Previous attempts at sharing relatively small logcats have been difficult as it seems recordings get very bulky indeed without a disconnect happening. Then I'll shut down recording and it'll disconnect within a second or two. My luck I guess.

Uninstalled the crapware with Revo. Found Snoopstitch on the Play Store - no need for your link with the weird installations. Ran a scan for network malware, which resulted in it asking if I wanted to allow a call to confirm something or other, so I said sure, do that. It promptly opened the dialer and called an area code 404 - Georgia, it seems, whether that's Georgia the country or Georgia USA I don't know yet, cooking dinner and no time to chase down everything. I let it dial, but it hung up, dialed itself again, then hung up. Then the number in Georgia dialed me back. I dismissed that. No added charges, thanks!

Will add more later. This stuff is all too weird and I have dinner to make for the family.

I'm not sure how you are collecting logcats, but i fyou're doing it over adb from a command line (in OS X or Linux, say) you can filter the output using the grep command, or you can filter within adb itself.

I think the callback from snoopsnitch is to verify your phone number-- by dismissing it you didn't verify it. If I'm not mistaken, snoopsnitch uses a 'crowd sourcing' type of method to collect data about where the bad cell towers are. It ties any reporting to a # and verifies the # so that if you are sending bogus or misleading ifnormation, it can be removed from the database. There are some videos about how IMSI-catchers work on youtube. I probably shouldn't have brought this up as it's extrmeely unlikely to be the cause of your issue, but it occurred to me so i mentioned it.

I've no familiarity with any of that. Using Windows 7 on a tablet. Used CatLog and the native terminal with the dmesg > /sdcard/dmesg.txt command thanks to a developer's instructions to get logs. I'm not at all conversant with command line stuff, just a user hoping to help while moving towards a fully realized and stable OS for my device. With sufficient instruction, step by step, I can deliver useful information. Otherwise all I can offer is reporting my experiences, as I did for many developers of Pocket PC software for a decade or so, while I did beta testing and reviews. So yeah, a log file from me is going to contain a lot of irrelevant stuff unless I'm told e actly how to narrow things down. I don't grock grep, sorry, and wouldn't know where to begin to filter an ADB thingy.

 

[tripLr]

Thank you for the mention and of course for your hard work, @jef_00

I'll flash it tomorrow afternoon cuz I have an early morning tomorrow.

I found the thread. Awesome

 

[fbarcenas]

Forgive my ignorance folks, but with the exception of the Exynos units, are there really any physical difference between the rest of the variants? Do they have different modems? NFC hardware? wifi hardware? etc? Because if just look at the specs of each variant the all seem to match (except Exynos units). It almost sounds like I could just flash a trlteW8 build into my trlteVZW unit and convert it. I'm sure I must be wrong, because everyone would be doing it. I just don't know why. So what is Samsung changing among these variants to make the different?

 

[Texas_Ace]

Just curious, Has anyone got Magisk working on the latest versions? it just bootloops for me when I try. I can live without it but it is nice to know it is an option if something pops up in the future.
