constantly scanning sd card - Xiaomi Mi A2 Lite Questions & Answers

Hi all!
I have always kept my music library on internal storage but I recently got a large sd card so I don't have to copy music back again every time I reset the phone. I am currently running stock Pie with June update, no root, bootloader locked.
Since I have put my music library on the sd card (30gb of music on a 64gb card) everytime I reboot or wake up the phone, I got a notification of "scanning sd card". And the music library in several players I have tried (pulsar, shuttle, musicolet) is empty and slowly repopulates.
When I first used the card I put it into the phone and formatted it as portable storage, then copied music in it.

I thought i was the only one with this problem. It happened after the PIE update. It was ok when i was on OREO. The same thing happened to my note 5 pro after the PIE update. It seems this is related to PIE rom, slowly remounting the sd card ofter boot. I changed a few cards before thinking it was the card problem. Hoping the devs would solve this problem with the next update.

Give PowerAmp a try, it's something, and works even after reboot

With the smaller sd card and music library on the phone storage I didn't have this problem, did you?

I'll give it a try, thx
EDIT: the same problem persists also with Poweramp.

I used memory card since i bought the phone, it's a 64 gb card. Never had any problem when i was on oreo. The music from internal storage seems to have no problem. Tried a few cards and seems like the 32 gb card loads faster. The 64 gb and 128 gb loads slowly and these are high speed read/wirte cards. Also if i didn't use the player after a few days i have to rescan the library again for the music to load. The same goes to some stuff on gallery too. Contents from memory card went blank and only viewable after a while.

I've also same issue on two individual A2 lite with 32gb SD cards (1x samsung & 1x intenso).
I expect that the SD card is unmounted when the device goes into sleep mode. If phone wakes up again the card will be mounted again.

I can also confirm this behavior.
May its possible to get some details with MatLog (during wakeup & sleep). But I'm not able to do this, cause my phone is not rooted.

I have this problem only with the music on sd. Images in the gallery show up correctly.
I have searched for this issue, and it seems a lot of people experienced it also with older android versions and phones. Someone fixed it with an app called Wakelock, others just changed their sd card or lived with it.

Guess i'll just live with it until this phone fails me. This problem doesn't really annoy me much. It's still pretty much a great phone for its price.

For me it's very frustrating, gallery does not work correct if i use it direct after unlock and also camera app will crash if used direct out of lockscreen and phone was in deep-spleep before (target directory is set do SD card). Sometimes (1-2%) if i wake up the phone the card is not mounted properly. Phone reports card is damaged, after reboot everything is fine again.

MicroSD problem [16GB C6]

I'm having trouble with my MicroSD card, Transcend 16 GB Class 6.
It only shows in 3 ways, all of them appear at different times:
1. My music would stop playing. DoubleTwist would show me "Memory Card Error". I fixed it by unmounting/remounting. Happens pretty often, once in 2 hours or so.
2. Market apps would not download. I fixed it by rebooting. Happens once a day.
3. The most serious one: my phone would freeze, and when I reboot, my wallpaper would be reset, all widgets break, Simple2EXT apps would be missing. After a reboot everything would be fine, but my wallpaper and widgets would need to be placed again.
I'm running CyanogenMod 7 RC2, S-ON. What do I do? Is my card a lost cause?
Should I return it? Is it fixable?

[Q] SD Card Woes

Hello everyone!
Last Christmas I got the 64gb SDXC Sandisk card which I have been looking forward to getting for quite some time.
I have a d2att running CM10.0 Stable so I quickly formatted that sucker to FAT32.
I put some of my HD videos on it and I was on my merry way.
A couple of days ago I was running low on internal storage, so I decided to move my music over to the roomy SD card. I took the SD card out of the phone and loaded it from my nicely tagged files from my external HD.
I put it back in the phone and it took a while for MediaScanner to do it's thing, understandable I just dropped around 10GB of music on top of it, no big deal.
After around 10-15 min of searching, the phone finally sped up and I fired up Google Music. What I found was half my music was tagged as "Unknown Artist" or not even showing up. Maybe one or two albums were working okay.
I was curious and tried multiple combinations of resetting the Media data and Google Music data in an attempt to get it to play nice.
No such luck however.
Out of curiosity I installed PowerAmp and had it scan my library, to my surprise all my music was properly tagged and sorted as it should after a long scanning session.
In addition to all of this every few start-ups I get the same lag from MediaScanner attempting to go through my SD card. It is very frustrating as I have to wait 10-15 min for my phone to be useful.
So overall I guess I'm really trying to find out why the MediaScanner lag is occurring here and there as well as to why it cannot find my music properly. Ideas or thoughts?

Lag caused by media scanner

Okay so every time media scanner is running, my phone becomes extremely laggy, as in 4-5 fps. Everything grinds to a halt, for example pressing on the menu button has a 1-2 second delay before the menu opens. I am using a 64GB SanDisk microSDXC card, and yes its genuine I tested it. I have also tried numerous different ways of formatting it (exfat and fat 32) with easeUS, fat32format and other programs. On top of this I have attempted to clear the media scanners data and then force a manual scan with Media Scanner as was suggested in other posts.
I know that media scanner is to blame because if I terminate its process the phone comes back to normal with 1-2 seconds. I should mention that this only happens when the SD card is inserted and has several files on it (currently 4622 songs). This behavior also happens on all kernels and roms I have tested (roms: stock unrooted, stock rooted, AOKP; kernels: stock, Lean kernel, Underwear, and KT747).
If anybody has any suggestions it would really be appreciated. I am open to anything and am willing to give more information if necessary such as processes using up CPU when this is happening or anything else.
Thank you.
Just put a .nomedia file on your sd card directory that has songs in it.

Wow this actually seems to be working. I haven't experienced any lag in a couple of hours. Do you know if this is a normal/common problem? i tried searching for it and couldn't find any mention of it.

[CM14]Spotify freezing and crashing phone

Hey Guys, newbie here!
I've been using CM13 for a while now. Recently my Spotify app started freezing and crashing my phone when accessing my 64GB MicroSD card. I can not reproduce this however since it seems to happen randomly. But when Spotif or my SD card are uninstalled i do not get these freezes.
I did a clean install of the most recent CM13 Nightly and the Experimental CM14 release, which did not yield any results other than corrupting my data file system. After fixing this, I now run in the Experimental CM14 without Spotify.
If you have ans Idea I would really appreciate the help from you guys.
*Edit* This is about the LG G3 D855 which I am using with a 64GB Sandisk MicroSD card.

Wow, reading that post, it's almost as if I posted it myself.
I have similar issues as you. But I'm using stock. I thought it was something wrong with my new 128gb microsd. I even gotten a new battery just in case, as I see other people pointing to these random issue to battery issue.
Until I realized Spotify somewhat actively caches stuff on my microsd card, plus the earlier issue of using network data in the background even when not actively in use (killed my wife's data usage for that month).
Issues I've seen are phone not waking up from black screen (or taking a really really long time to wake up), issue playing the next song with my regular mp3 player with songs stored on microsd, spotify freezing, bluetooth freeze on connect, etc.
Just recently I've just tried to clear all data/cache on the spotify app (took a long time, I clicked the button and went to sleep). Then as soon as I'm back on spotify, I go to settings and tell it to cache on phone sd instead of external. So far my phone seem to be running better. Will have to wait a few more days to see how it goes. Hope this helps (for myself as well : ) )

LineageOS GT-1915 serranoltexx: icons disappear in launcher

Running the latest nightly build 14.1-20171006 LineageOS, some icons disappear from the launcher screen when I restart the device using my SD card as adoptable storage.
As far as I can guess from other posts, this is likely an issue of the SD card being mounted too slow, so that the launcher removes the shortcuts. However, I am using a SanDisk SD 64Gb SD card Class 10 (C10) / UHS Class 1 (U1) and I double-checked this behavior with an other SD Card with very much the same specs (SanDisk 64 Gb, C10, a litte bit older card). So there is not much to improve on the side of the SD card...
Does somebody have an idea how to solve this while keeping the SD card as adoptable storage? (It is quite obvious that not using adoptable storage will solve this issue, but this is not really an option...)
An other little bug with the current nightly is, that setting a WiFi to trigger a profile that removes the device lock screen makes the home button stop working. (However, I can disable WiFi, lock the device and unlock it again, and my home button works again.)
