[LG V20 Guides, News, & Discussion] xdav20:
Just reporting back what I have observed and experienced lately.

The TWN variant of H990DS, in OP partition, /OP/OPEN_TW_DS/apps, there is an app called friDayAppAssistant.apk. All Mobile and Desktop Antivirus scanners detect it as a threat, Android/Adware.Commplat to be precise. I have removed mine to be on the safe side. Apparently, the app is some sort of free social media.

When I copy files either from USB or Internal storage to external SD certain files are then renamed. I have disabled both MTP services, without any adverse effect, but the renaming issue remained. For instance, all Titaniumbackup files with .gz files are renamed to gz.zip and .properties are renamed to .properties.txt. This is not the only issue and I have to do a lot more because of this annoying issues. Does anyone know what service is responsible for this so I can stop it please?

Rant break, Android 7.0 (a.k.a Nougat) is a regression rather than progression. My productivity level has significantly reduced and I have to do a lot more for the same thing. I can discuss in details to prove how brainless Google developers can be, but this is not the place.

Out of nowhere, I get this random digit zero appended to the folders and files names.

After TWRP's backup kept failing in which I had to pull the battery out, I discovered very unpleasant things. All my music files were disappeared but not the folders, found some junks in sub-folders previously when usually such files should be placed in LOST.DIR folder, and generally slow file operations for sometime. I would say I experienced most things on both of my H990DS phones. Both SD Cards were formated by Phone hence, FAT32 format. I took both out and used the USB SDCard reader to see what Windows 7 does when I plug them in. I immediately got promoted with Scan to fix option. Both contained all sort of issues. Decided to reformat them with EaseUS Win app to FAT32 in case Android corrupting the SD Card during the format process. Took me until 4am to get everything back to normal again.

I ended up reformatting all USB drives back to FAT32 as well. The old problem with my Lexar USB Drive has returned. Everytime I use it in Android then Windows 7 has to scan it first, no such issue in Stock as I tested before. This happens to both phones on jalex>werewolf kernel where one of them always remained on jalex v0.1 kernel but the other one I flashed emdroidle's v0.2.3a experiment6 before reflashing jahlex's again when it crashed the system after I inserted USB Drive while screen was off.

TWRP backup works again but something tells me all the problems will reoccure sooner or later. I cannot use neither of my phones as long as I don't feel my setup is reliable. Three years with constant intense use of SD Card and Internal storage with my LG G Pro 2, never experienced one the mentioned problems. Only moved from Kitkat to Lollipop a month ago when I purchased H990DS. You may have forgotten, but life with Kitkat and even Lollipop was tremendously easier. Nougat is a nightmare for both developers and users. Well done, multibillion dollars company.

I don't know where the underlying issue is but one way or the other all custom kernels have disk operation issues and USB storage which may or may not be correlated. If you are not experiencing these problems because, perhaps, you don't use the SD Card as extensively as I do.

Final Rant Break, I think restricting external storage from apps was a brilliant idea but the implementation was awful. Now that I cannot edit my files, to do so, I have to move it first to the internal storage where all apps can access, read, and write unrestricted. Great security feature Google. The options should have been given to the users, same as Contacts, SMS, and so on.

I don't know if anyone is aware of this or not. A single brain washing article on Android Authority (I may be incorrect about the source) web site stated how the absent of Internet permission per app was justified with some BS reasons and many bought into it. The most unlikely manufacturer, [MENTION=2021504]huawei[/MENTION], that everyone was afraid of just less than five years ago, in fact allow restriction of Background, Mobile, and Wifi per app on Mediapad M3 with 4G. Well done Huawei.
