Strange SD card problems and other comments

I have the N910T, and I'm using a Samsung 256GB card (which also has an ext2 partition for link2sd, on my previous rom)

My previous rom was stock EQI2, and that is my modem version.

I encountered the following:

1. After flashing RR+gaps, and leaving the SD card in, I get asked to chose a language. Then I see "Just a sec" or something like that, with a spinning circle, from time to time the screen turns black, and then comes back, but boot never finishes. (clean wipe)

1a. If I take the SD card out after flashing both, installation proceeds to the end.

1b If I flash just RR, not gaps, and leave SD card in, first boot proceeds to the end.

2. After installation finishes (with or without gaps), on booting with the SD card. I see two notifications: Discover Trust, and "Checking SD card..". If I try to unlock the phone at this stage, I see "Phone is starting". After various unlock attempts, it usually does manage to finish booting.

When I boot without SD card, I can boot without any problem.

The same problem occurs with all Pie ROMs I've tried. Except that others are stuck in "Phone is starting", whereas RR eventually manages to boot.

If it will help I can send logcat of these boots.

3. Camera doesn't work. On unofficial LineageOS 16.0 it does work. Other camera apps do work.

4. I tried to enable Wifi calling. I modified build.prop as described, and *#*#4636#*#* does show that the phone is capable of

WifiCalling. I can also enable Wifi preferred in Phone settings. But I think that is it. I don't think Wifi calling actually works. Same phone, same network (mint on tmobile) I did have wifi calling in my previous rom.

Download section have Bootloader/Modem. Do i have to use them during install or is those just if problems occure? If needed how to choose right? Didnt match perfectly for current numbers.
[Galaxy Note 4 Android Development (Snapdragon)] BeckPC:
It may be missing a few 'improved' features, but it snaps a photo when you press the button. It does it MUCH faster than the ones built into these phones. At least with this camera, you might actually catch what you wanted to snap a photo of, instead of the back of their head. With the long delay, the action has already passed.
[Galaxy Note 4 Android Development (Snapdragon)] sronweb:
If you don't have problems I guess it's ok to keep the original bootloader/modem. They are anyway not specific for Pie. In case you can compare with the version that you have and the one for your region and provider or use the international version.
[Galaxy Note 4 Android Development (Snapdragon)] Tilagoon:
Looks great but could you manage to save the pictures to the external SD card ?? :confused:
[Galaxy Note 4 Android Development (Snapdragon)] novaol:
Hi Mobspyguy, I really love the ROM very much but till now you have not answered my question on the issue when the phone is off, it drained twice as much power as compared to a phone that are ON state. Is there something we can disable on any background apps, drivers or anything that might still be turned ON even the phone is powered OFF??
[Galaxy Note 4 Android Development (Snapdragon)] bobkoure:
It (camera app writing to either local storage or sd card) seems to be recently fixed in LineageOS 16 (build 05/12 and later) but those builds also take for...r...e...ver to boot unless you've cleared Dalvic/cache just before boot... It's been dubbed 'infini-boot'. My wife has a trlte running LOS16 build 02/something and both camera and boot are OK. I don't really care about the camera as I usually have a DSLR in my bag - but she definitely does.
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
The ROM cannot drain your battery if the phone is powered down....
[Galaxy Note 4 Android Development (Snapdragon)] techeazy:
Just flashed this ROM on my Galaxy Note 4 and THANK YOU! The ongoing rebooting itself issue has stopped. It's not the battery. It's the stock Marshmallow ROM. So far so good with this 9.0 ROM. THX again!
[Galaxy Note 4 Android Development (Snapdragon)] Note4Addict:
Thanks for this input. I'll be sure to give it a try. One thing though is that Kernel Adiutor doesn't seem to keep it's settings as it reverts all the time back to the intellactive govenor and the MPDecision Hotplug at restart. Is there any workaround or alternative to avoid this behavior?
[Galaxy Note 4 Android Development (Snapdragon)] Tilagoon:
Did you activate the switch "apply at startup" (or equivalent) ?? :confused:
[Galaxy Note 4 Android Development (Snapdragon)] Note4Addict:
Yes I did. Nevertheless it keeps reverting. If I remember correctly, I read somewhere in the Kernel Adiutor forum that this is due to the lack of development for the newer Android versions.

Really you prolly should be using: https://xdaforums.com/android/apps-games/app-smartpack-kernel-manager-t3854717

[MENTION=6363151]mobspyguy[/MENTION] :

Perhaps we can have SmartPack Kernel Manager added instead of KA by default - lol, it would save me one step when setting up :)

p.s. i use the same settings as you, and no drama

I might add that ForceDoze still works well on Pie. Of course as always, only if you set it up properly.

But as ive said before (at lest in the LOS thread) installing Greenify post Android 7/Nougat is pretty much pointless...as agreed by Greenify geeks..dont take my word for it
[Galaxy Note 4 Android Development (Snapdragon)] novaol:
I've always thought it is the battery problem but after spending money in getting another new battery, same issues. I've also sent the phone to check if there is any faults on the motherboard and the guys gave a thumbs up stating my phone is without faults. Samsung service center guys kept asking me "Its time to upgrade the phone". Hee hee

So did the impossible and that is to restore the ROM back to factory ROM and boom the problem is gone. For 1 week I tried on the original ROM and non of the power drain issues were found, turning OFF for the night and powered ON in the mornings and the battery level is almost the same or just dropped a little. I switched back to this latest ROM build as to those of the past versions, and the problem resurfaced again.
[Galaxy Note 4 Android Development (Snapdragon)] ghostwheel:
Try off overnight, with battery removed. Then the phone can really not drain the battery!

Another possibility is that the draining does not happen while off, but instead that the battery percentage is wrong, either before or after powerdown. How does the drain depend on how long the phone is powered off?
[Galaxy Note 4 Android Development (Snapdragon)] MaXi32:
Last time I use wanam xposed. May I know which version of xposed do you use? Can you share the link? I'm afraid of bootloop coz of xposed.
[Galaxy Note 4 Android Development (Snapdragon)] Isaac_T:
But the battery drain while phone is off has been a lineage issue since Oreo I remember, and maybe even before that. It's something that the phone doesn't completely go off! If I remember, it was something that you have to have a charger plugged in or something when you turn it off.

Either turn the phone off and remove the battery, or leave the phone on. I never turn it off because I use it as alarm clock. I have an automate flow that disables WiFi, 4G and put the phone in power saving mode at night, and in the morning it turns everything on again. I use around 1-2% at night.
[Galaxy Note 4 Android Development (Snapdragon)] wiktor44:
Is anyone else having issues with usb transfer? through a search in the settings ive tried to change it to MTP mode from charging only however my phone still doesn't appear on my computer when plugged in with a usb. I've tried a brand new cable and the problem persists. If someone else could test trying to transfer via files via usb and confirm that would be great! (SM910F)
[Galaxy Note 4 Android Development (Snapdragon)] tbmmbt:
My SM910F transfers via USB fine. After you connect the cable pull down the notification shade and tap the 'Charging this device via USB' option at the bottom. Then change it to 'File transfer'.
[Galaxy Note 4 Android Development (Snapdragon)] wiktor44:
I don't get that option, ive tried doing it through the settings but the options are all greyed out. There should be an screenshot attached to show what I mean.

**** edit/ solution ---- turns out my laptops usb ports arent recognising android devices - rom is fine with regards to usb ports
[Galaxy Note 4 Android Development (Snapdragon)] tbmmbt:
Hmm, that's strange then. I have the same options but I can select all of them. When you say you've done it through settings, was that via the 'Developer options' section? I've also got it set to 'File transfer' in that section too (see screenshots) but that shouldn't matter, you should still be able to change it when you plug it in without it being greyed out.

I'll see if I can think of something else that might cause the problem, maybe someone else can suggest something too.
[Galaxy Note 4 Android Development (Snapdragon)] ALPHA85:
Guys I'm stuck with a big problem , I can't activate apps services I don't remember which settings I changed
[Galaxy Note 4 Android Development (Snapdragon)] tbmmbt:
The general consensus these days seems to be that Greenify on anything after Nougat is probably not going to make any noticeable difference. I used to use it on MM and tried it briefly on Pie but it did nothing for me so I got rid of it.
[Galaxy Note 4 Android Development (Snapdragon)] andropest:
As Isaac_T already wrote, this problem occours also on other Lineage based ROMs. The S5+ with LOS also have/had the same problem. I think there is a workarround. Don't power off the phone directly but reboot to TWRP and shut it down from there. IIRC someone wrote that there is no batterie drain when the phone is powered off from within TWRP.
[Galaxy Note 4 Android Development (Snapdragon)] jufegoco:
It's something related with smart pixels or other settings for "superposición de pantalla" sorry but I don't remember how to say that in English... [emoji3526]

Exactly

Wasting your time and prolly adding CPU cycles using Greenify on anything above Nougat, had this convo with the Greenify geeks last year and confirmed its near pointless on anything above Nougat

The best you can do (what i do at least) is:

Background Permissions

RunInBackgroundPermissionSetter: https://github.com/MrBIMC/RunInBackgroundPermissionSetter/releases

Note: the 1.5 version on github is the latest version, later than in XDA Labs

- disallow background running on apps you dont need running in foreground (yes you can do this via PrivacyGuard, but this is easier)

Autorun Apps

Stop apps running at boot up (sadly autoruns and similar apps dont work anymore - if anyone knows of an app that does startup entrie son Pie, let me know)

- System > Advanced > Developer Options > Memory > Apps Started At Boot...click on any you dont wanted started at boot and click on Start At Power Up and set to Ignore

Doze Mode

ForceDoze still works just fine on Pie - https://xdaforums.com/android/apps-games/app-forcedoze-force-doze-mode-screen-t3377694

- know how it works, how to set it up and it works a treat
[Galaxy Note 4 Android Development (Snapdragon)] tullian:
Or, since it doesn't cost more than a bit of time, one just tries it instead of trusting blanket statements.

The result for my 910F on RR7 was a reduction in battery drain over night from 1.7 %/h to 0.4 %/h. That is wifi off, of course.

It was even better on AICP 13 where I could use Greenify's Xposed features.
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
Or you could re-read the part where even Greenifys creators agreed above Nougat its next to useless....and possibly adverse :)

and direct quote form that convo:

Cant be any clearer than that....
[Galaxy Note 4 Android Development (Snapdragon)] tullian:
There is a near infinite number of combinations of devices, installed apps and people's preferences to have wifi, location, bt, mobile data on or off. I'm sure that Greenify doesn't do much or even anything for many of those. Whatever "many" may be.

All I'm saying is that Greenify demonstrably improved battery drain for me, so saying "above Nougat its next to useless....and possibly adverse" is not generally and unconditionally true.
[Galaxy Note 4 Android Development (Snapdragon)] MaXi32:
I can confirm GPS locking has issue.

I have N910F bought from USA and I live in Malaysia. I have read some posts in this thread to add or uncomment NTP_SERVER. I tried them all, reboot many times. I also tried asia.pool.ntp.org

I also tried flashing few bootloader and modem, using ripee, the stock modem and bootloader and I cannot get it to lock. The GPS can see the satellites but it cannot lock.

Just now, I went back to stock ROM to check whether I have issue with hardware, the GPS work very well in stock. I'm not giving up to find solutions yet (use GPS everyday to work). Is there anyone having the same problem with GPS?
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
Really? Read it a second time, or is that 3rd....ive lost count

The use of the words vast majority are used and you still think thats not general enough

We need to buy you a dictionary and thesaurus just to be safe :) :)

All the power to you if youve spent x hours getting some semblence of positive use out of it ( in one small sample set which you will probably never match again), but again the vast majority will not

Hopefully this even clearer than my previous already very clearer reply...but if you want ot discount myself and the makers and fanboys of Greenify, you be you...

---------- Post added at 11:58 AM ---------- Previous post was at 11:56 AM ----------

Yup, even with the normal gps.conf tweaks i use i find it takes ages to get a lock and it seems to toggle the fix off and on...you can watch the GPS icon dissapear and reappear int he status bar....i think this is common across the LOS 16 base though....
[Galaxy Note 4 Android Development (Snapdragon)] MaXi32:
Just now I use the OFFICIAL HAVOC-OSv2 Android 9.0 that can found from this forum and the GPS lock is working fine less than 10 seconds lock. Isn't Havoc based on LOS 16 ?

Edit: I also tried changing kernel to flashpoint v3 and didn't help too.
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
It may use LOS as a base, but ROM devs then often cherry pick from other repos....which is prolly whats happened with Havoc

I have my own issues with Havoc....lets not go there :)

Flashpoint Pie v1 and v2 are better than v3, it has the odd issue...cant promise you it will solve the GPS issue as i havent used Flashpoint kernel in a while ....and not sure its kernel related...
[Galaxy Note 4 Android Development (Snapdragon)] tullian:
Good grief...
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
Glad it finally seems to have sunk in :)
[Galaxy Note 4 Android Development (Snapdragon)] tullian:
Interesting interpretation.

Thanks Isaac, will take a try on this method. Tks buddy

Btw.: I'm andropest, not Isaac_T. :cowboy:
[Galaxy Note 4 Android Development (Snapdragon)] MaXi32:
I also tested the RR-Oreo build and it has no issue with GPS lock. I will flash this ROM again when the next ROM is update and hopefully it has great news on GPS. Currently I'm using stock ROM at the moment due to heavily rely on GPS.

Thank you so much!
[Galaxy Note 4 Android Development (Snapdragon)] novaol:
Oops!! My bad.. But anyway after tested the method for one night. TWRP's method works when shutdown thru this method, it does not drained the battery. Cheers

What happened here with my N910F 7.02?

I pressed power button, chosed reboot, system and to my surprise all my pics and movies in the DCIM folder are gone, all subfolders still present. All received pics in the whatsapp folder gone, all sent pics in whatsapp remained. All pics only affected on the internal storrage.

Once i also rebooted to recovery to restore from a plugged in usbstick -backup was gone. That was the reason i always have chosen shut down and started normaly, but today ive forgotten. I also checked for emmc bug, but everything ok.

Also checked for virus - nothing.

WHat happened yesterday: i had to search s pic, but the galery didn't showed files from external sd card. So i long pressed gallery, chosed "app info" and stopped the app. I also tried app info and cleared cache, but the galery still didn't show up files from the external sd. I've let it as it was. today i rebooted and all is gone. maybe it hase something to do with with the galery and cache clearing. I don't know.

What app do your recomand for file recovery?

Thanks
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
Dunno how you managed to erase the files, sometimes its just a momentary glitch in the sdcard being read, its happened to me. Always keep a backup...i always have 2 independent backups of anything i love. Dont learn the hard before you adopt the same strategy

If you can plug it into a PC via card adapter, try photorec/testdisk, always, its very good and free

[Galaxy Note 4 Android Development (Snapdragon)] xda-graphite:
Thank you

I've lost some files 2 times from external sd (not cheap ones) on samsung phones.

So i made some backups.

I didnt' thought to loose the files from the internal drive.

exact workflow:

i've opened the galery to search a pic and realized that only files from internal starrage are shown, external sd card files are missing in galery. (with an file explorer files on external card are ok).

by app info i forced terminate the galery, restarted it but still the same.

so i decided to clear cache of the galery also by app info way and forgot about it.

today i restarted the phone and nearly all picture, videos and mp3 files from the internal storage are gone

inerestingly nearly all, in the whatsapp directory all jpg in the sent directory are still there.
[Galaxy Note 4 Android Development (Snapdragon)] 73sydney:
Sorry i skipped over the part where you said it was the internal storage, sorry. Dont ask me to explain that, ive never seen it happen.....and ive flashed more ROM's than most people have had hot dinners. Never lost anything off internal storage ever.
[Galaxy Note 4 Android Development (Snapdragon)] xda-graphite:
Me too.

That's the reason why i didn't understand what hapened here.

I don't want to try it once more.

my first thought is it deleted the files instead of the cache

gps is working fine and locks fast. ROM from May 15th.

Would like to change saving folder for pics as well but dunno how.
[Galaxy Note 4 Android Development (Snapdragon)] bobkoure:
With the camera that comes with the ROM ('Camera'), I don't think that's possible - but you can with OpenCamera (free/no ads/open source) on Google Play. It's in Settings/More Camera Controls. If you want to write to a folder on your micro SD card, enable 'Use Storage Access Framework', then tap 'Save Location' and navigate to the folder you want OC to write to.

---------- Post added at 11:42 AM ---------- Previous post was at 11:34 AM ----------

If I turn on 'Back button long press kills foreground app' in Developer Options, it only sort of works (long delay, some apps won't close)

BUT if I go to Settings Buttons/Hardware Keys and set a long press on the back button to custom action 'force close app' it works perfectly!

Took me a bit to figure that this custom action was available, thought I'd ought to mention it in case somebody else is trying to make that developer option work.

1. What is your phone model? Mine is N910F.

2. may I know what is your modem or bootloader version, did you flash the provided modem and bootloader?

3. Also do you have any custom kernel other than default?

4. Did you make any changes to the gps.conf?

Have to ask though why is it that SD card (micro SD card) does not show up in titanium nor can I save to it - I've read google has denied access or changed something not sure how true it is but since going from 4.4.4 to 7.1.2 I saw it, and again see it in android 9 - that SD card isn't readily accessible.. Is there a work around or can force ad card to be read/write globally

[Galaxy Note 4 Android Development (Snapdragon)] steepdgaf:
Are you referring to titanium backup not accessing external storage? If so....

Go to Preferences -> Backup Folder Location.

Click on Storage provider at the top (it's not obvious that it's clickable).

*Open Titanium. Click menu bottom.

Click on DocumentProvider storage. That will take you to a File Manager interface. You may have to click on the 3-dot menu on the top-right to enable the (external) SD card to be shown, then click the menu lines in the top-left and select your SD card, and click the "Select" at the bottom right. (You don't have to select your Titanium Backup folder here, you're just using this to get access to your SD Card.)

Now you should be back in Titanium Backup and you can browse like you used to to get to your preferred backup folder on your external SD Card.

If this is not what you are referring to then I apologize...
