I am trying to set up my new phone and want to understand what information is backed up by chrome in Android/Windows which I can restore. My questions are: Does chrome back up cache, local data like temp files, login data and thumbnails, so that I don't need to set up apps again I new phone, from what I read on internet, apparently not

I'm trying to figure out what is stored where on my Android phone (an unrooted Samsung Galaxy S8 with an SD card). I can examine the phone's contents either via any of the several file manager apps I've installed, or by mounting the entire phone as a network drive on my Windows 10 machine. My File Manager App shows me the contents of "Main Storage" and the contents of "SD Card". The contents of "Main Storage" show up on the network drive in a directory called /sdcard. The contents of "SD Card" show up on the network drive in a directory called /storage/0000-0000 . This is very odd, since the directory called "/sdcard" on the network drive is the *opposite* of the directory called "SD Card" in the File Manager app. The File Manager app shows 57 gigs total in "Main Storage" and 256 gigs in "SD Card". This suggests to me that the former is the phone's built-in memory and the latter is the actual SD card. But I'm thrown for a loop by the fact that the former is called "/sdcard" and the latter is called "storage/0000-0000", which seems backward. I could, of course, pull the SD card out of the phone and examine its contents directly on another device, but I'm squeamish about handling the card. And no matter what I learned, I'd still be curious about the odd naming conventions. So: Question 1: What's going on? What's in which directory? Question 2: If I want to back up all of the data (but not the system files or software) on my phone, does it suffice to make copies of /sdcard and /storage/0000-0000, or are there other places data might be stored? Additional Info: The App X-plore confirms the odd naming, in that it shows me two directories, one named both "Phone Memory" and /sdcard (it shows the former in bold and the latter in roman, both labeling the same directory) and another named both "SD card" and /storage/0000-0000.

I have a Asus Zenfone 2 and a few days ago it ran out of battery and turned off. Then after I charged it up and restarted it, it wouldn't turn on. It gets to the logo and the loading circle and just gets stuck there forever. I can get into recovery, but can't do anything in recovery, because everything gives this error: > E:failed to mount /cache (invalid argument) Trying to wipe cache, factory reset the phone, mount /system, flash a ROM from SD card, ADB sideload, everything gives the error multiple times. Factory reset formats /data fine, but when it gets to /cache, gives the error and aborts. Same thing with fastboot. I tried to flash TWRP (I have stock recovery) and I tried to erase and format cache through fastboot, but both give this error: > FAILED (remote: 'Can not mount the necessary partition') > >fastboot: error: Command failed Is there anything I can do to format the phone or somehow rebuild the partitions without being able to flash anything via recovery or fastboot? I don't know if tools like AFT or xfstk can do anything for me. Edit: I don't think the EMMC chip is dead, because the recovery partition is still fine, I can still boot into recovery and when I did a factory reset, it formatted /data without any errors, only had an error when it started formatting /cache. When I was looking for a solution to this problem, I read somewhere that sometimes when the device gets interrupted, like when it shuts down suddenly, to prevent data loss android would change permissions on the /cache partition to read only or something like that. This would certainly explain what happened to my phone. Just need to think of a way to access ADB shell on it to try to change permissions. Shell doesn't work in ADB sideload mode, that's the only ADB thing the stock recovery has. Is that a similar thing in fastboot by any chance?

I recently bought an Intenso microSDXC UHS-I Premium card, formatted it as internal storage, and the content has been moved without any errors. But after that, the phone started having several issues: - Most photos, videos, music, and recorded audio files are missing. - Some apps—like CamScanner, Foxit PDF Reader, and the camera—don’t work. - WhatsApp media (voices, images, videos) can’t be downloaded or saved. - App updates can’t be installed. - Storage shows a negative value (see attached photo). I’ve tried common fixes online and contacted the manufacturers, but nothing has worked. I also couldn’t find an option to reformat or separate the internal storage from the SD card. What would be the best next step? Should I try reinserting the SD card and choosing "forget" option, enable “Force allow apps on external” in Developer Options, or is there a better solution to recover the files and resolve the storage issues? - Device Name: Redmi Note 9 Pro - MIUI version: MIUI Global 12.0.3 Stable 12.0.3.0(QJZMIXM) - Android version: 10 QKQ1.191215.002

After I got my phone restored from an nandroid backup, I found almost all apps cannot gain access to /sdcard/ (internal storage), including ES file manager, Z archiver and so on. When any of these apps access /sdcard/, or any other equivalent folders like /storage/emulated/0, /storage/emulated/legacy, /storage/sdcard0, they only shows a blank directory, and I cannot create any file or folder. When I try with the stock file manager (My files), it does show the files, but i cannot rename, edit, or create anything. Android File manager is able to copy most of my files out. But It stucks when I try to create a folder or send something. I tried to re-flash the same ROM again (which worked perfectly before), the issue remains. I have backed up important data from /sdcard/. In terminal emulator, cd sdcard, ls gives opendir failed: permission denied. Then I tried su, ls shows the correct directory. How should I fix it? Extra: I found a new folder called knox-emulated in /storage which is not there before. External SD card (/storage/extSdCard) works fine. Device Information: Samsung Galaxy Note 3, Android 4.4.2 Rooted, with a custom ROM modified based on the Stock ROM. Custom recovery installed.

This is the same to this question: https://android.stackexchange.com/questions/57844/cant-delete-file-in-download-folder But for me, the answer is not clear, as per the OP's answer 'he turned on the SD Maid app' but did not state what option in SD Maid resolved the issue. The OP stated as well 'he deleted the whole directory' but not specified if using SD Maid or PC. We have the same scenario where I redownloaded the same file, and after copying it to the exact location where I'm having an issue, it made two identical files and what I tried so far: 1. Highlighted both items and deleted them using SD Maid, it says success but after a refresh, it retains the other file with 0 bytes. 2. Connected my phone to PC as MTP and tried to delete it from there. What I noticed is it only shows one file, unlike looking in any Android file manager. It says success but checking it again on the phone it retains still the file with 0 bytes. 3. Tried apps in Play Store that says secure delete that uses a different algorithm but still, after it says yes, the same scenario occurs above. 4. Perform wipe cache partition in the stock recovery. 5. Clear data and cache of stock file manager. I know my last resort would be a complete factory reset, but is there any other way?

I’m using an LG Tribute phone (Virgin Mobile service). The default email app installed is synced with my Microsoft Outlook account. I only use this account for ticket confirmations, boarding passes and the like. However, recently I noticed it is taking up the following storage: Total: 635 MB App: 24.5 MB App (SD Card): 0 MB Data: 610 MB Data (SD Card): 0 MB Considering my phone only has 2 GB of storage, the above is a heavy price to pay. When I hit the “Clear Data” button, I get the message “All this app’s data will be deleted permanently. This includes all files, settings, accounts, databases, etc.” I don’t want to delete my account so I was wondering if there is any other way to slim down how much data my Email application is using?

I'm getting tired of deleting apps to install an app. Right now I need every app I got but also need to download another app. I got no more space left. I've searched high and low for a way to move my apps, completely, to SD card but to no avail. And I don't want to "link" them to SD. I want to "move" them to create space. Can anyone point me in the right direction please? Thanks! Android 7 | Rooted | Moto C Plus

I accidentally deleted my WhatsApp database folder and have lost all my chat history. How can I restore it? Deleted from phone's internal storage, Android 7, no root access and no other copy of the folder exists. I checked out multiple other links, e.g: https://android.stackexchange.com/questions/93455/recover-whatsapp-messages-database-folder-deleted | https://android.stackexchange.com/questions/173256/recover-whats-app-database-files-crypt12 | https://android.stackexchange.com/questions/208106/how-to-recover-a-deleted-file-from-data-partition etc ...however, the information is old or dealing with rooted devices or dealing with recovery from backups or dealing with SD cards etc none of which work for my situation. I've also tried Tenorshare UltData, but it can't retrieve .crypt12 files. Is there a way to recover and restore my databases/chats?

Is it possible to edit the fstab to mount /data, /cache, etc. from a different partition on the 1. internal memory? 2. external SD card? Details: The default partition for /data and /cache is too small for my needs and I can manage to format the (internal) /sdcard in ext4. My question may superficially seem to be like other questions asking for a way to increase the size of /data, but it's not. Here's why: 1. I need to do it *specifically* by editing fstab, which is the usual way of doing the same thing on a GNU/Linux desktop. 2. The other questions don't ask about /cache and other partitions.

I'm using Moto G 2nd Gen with Android version 6.0. I was using an external SD Card as Internal storage, and I guess it has encrypted the card. Recently, my phone started to work abnormally. It randomly fails to recognize the storage. After a device reboot, it would work for some time and fail again. In the "Storage & USB" settings menu, I clicked "Forget" on the external SD card. Then I realized I cannot access the data from my computer using the SD card reader. How can I re-plug the SD card back as Internal Storage without formatting it again?

You may note the almost duplicate title from this question . It keeps coming up when trying to solve my current issue. I created a little web app to help at work. Just some HTML and JavaScript, and before Android started enforcing the Scoped Storage, I had no issues using it. Now when I try to load the URL (ie: file:///storage/emulated/0/__MyDocs/SignInTracker.html) I get an access denied error. I could use Firefox, but it seems to be because it's not yet using the Scoped Storage standard, which if I understand correctly, will be a requirement in the next Android version, so that means I cannot rely on it working in the future. Also, Firefox just doesn't run as nicely as Chrome. Is there a proper way for a non-Android-developer to use a local web app like this? Is there perhaps a location on the phone where I can place my .html and .js files that will allow Chrome to access them without issues? At work, I'm not online or connected to anything, so loading from another server/computer is not an option. For reference: My Chrome version is 79.0.3945.116, my Firefox version is 68.4.1, and my phone OS is Android 10; Pixel Build/QP1A.191005.007.A1.

My device has terrible adb support. Can I install a ROM without using adb?

Device: Nexus 7 (2013 WIFI) ROM: AOKP_FLO_KITKAT_NIGHTLY_2014-07-31 Rooted: Yes Recovery: TWRP (Not sure if this is needed) I am posting this because I recently started getting "insufficient storage" error on my device. I've had this before and I knew exactly had to fix it because I had come back from a vacation then and there were a lot of pictures on the device; So it was a simple matter of moving all the pictures and videos off the device for it to start working again. This time however it is a little confusing for me. I will start with some pictures: *Settings > Storage* / *ES File Explorer* > Top_left menu > Tools drop-down > SD Card Analyst (click images for larger variants) So far everything looks fine, I seem to have a lot of space left to install one measly app right? Just to confirm, I used Clean Master to try to move some apps to device storage: Clean Master > App Manager > Move No gimmicks here, Clean Master sees that I only have one storage medium on my device. So why do I get these errors? *Google play* (Trying to install an app that is less than 1MB in size) / AIDE (Trying to run an app) I'm just confused about the whole thing. Everything else seems to be saying I **have** enough space, but apps are not being installed because I **don't have** enough. What can I do here? EDIT: Even more weirdness, it won't let me install the 300Kb file with the image I posted above, but it lets me install a 3Mb file from the playstore. Basically I can install some apps but not others and it doesn't matter the size, my device just wants to make me crazy no problem. Ex. This app (2.6M) installed fine, but this one (2.1M) didn't due to "Not enough space". **What I have tried:** - http://forum.xda-developers.com/showthread.php?t=1834105 - Installing and running DiskUsage and here is a screnshot: Couple observations: --> It let me install this App and still not letting me install the other apps I have tried with the insufficient memory message still showing --> The above pic shows that I have enough space left on the /data partition to install atleast A LOT of apps! - Output of running the df command: Note I have tried the solution posted at the "Possible Duplicate" link and it did not work nor did I expect it to. The problem here is not that I have insufficient space to install apps because as you can see, I have a lot of space and I am able to install some apps. The problem is deeper than that and probably has to do with the way files are installed on my tablet

I know there are tons of questions about this, but I have tried many possible solutions to no avail. I believe the "Out of space" error is misleading... I have a problem: **I cannot install any .apk file** no matter what I try... I can install apps using **Play Store** though. When I tap on an APK file in any file explorer, Android Package Installer launches. I tap the INSTALL button but I always got the following error: > Out of space {AnyAPKApp} couldn't be installed. Free up some space and > try again. I have *plenty* of space, but even a tiny 248 KB APK won't install with the same argument... This is the only problem I have with the ROM and it is very frustrating... First, the details of my case: - *Device:* Samsung Galaxy Grand Prime+ SM-G532M, alias Galaxy J2 Prime (Xtreme detects my device as *Model Number:* SM-G950F) - *Android:* 6.0.1 - *ROM:* Xtreme Ultimate V6.0 (15.07.2018) - *TWRP:* 3.0.2-0 - *Magisk:* v17.1 - *Magisk Manager:* 6.0.1 (151) - *Storage:* Adoptable - *Internal storage:* 7.02 GB used of 8.00 GB - *SD card:* 9.09 GB used of 14.70 GB - *Root Essentials "View storage used":* 9759/15787 MB (62%) - *DiskUsage analysis:* /system = 2.94 GiB; Free space 1.61 GiB I've already done my homework and tried all of the following to no avail: 1. Move all movable apps to SD 2. Enable Adoptable storage 3. Wipe *Dalvik / ART Cache* and *Cache* partitions with TWRP 4. Full clean with *SD Maid PRO* 5. Force move apps to SD using *SD Maid PRO* 6. Uninstall *Google Play Services* and *Google Play Store* updates 7. Overcome *unauthorized device* issue while using ADB 8. Trying to install APK using ADB (e.g. adb install someApp.apk). I got: Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] 9. Delete /data/log contents as suggested here 10. Attempt to install in Safe Mode 11. Using Termux and the df command, I got the following output and there is free space in each partition: df output" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> 12. Using pm install test.apk in a terminal emulator (*Termux*) I got [INSTALL_FAILED_INVALID_URI]. Using full path pm install /storage/emulated/0/Download/test.apk I got the same error: Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] The problem still remains. I think this is not really related to the full storage device error, I have plenty and the error seems misleading. It has to be something else... I gave as much info as I thought it was useful. If more is needed, just tell me to share it. I hope you can give me some advice to try to overcome this annoying issue. *P.S. I'll add more attempts to my list as I try them.*

I know, similar posts about this topic have been discussed but reading through them couldn't solve my problem: I have a 5-year-old Redmi note 8 pro (MIUI 12.5.7, Android 11). The internal storage is 64GB of which 42.4GB are occupied but I just cannot find out by what data. I plugged the phone into my Windows 10 pc with the option "show hidden files" activated in Windows Explorer but I still could not see any files that would take that much space. When I select all folders of my internal data in win explorer manually and sum up their size I only get 118MB. I have deleted 1-2GB with DiskUsage but still 40GB remain. The apps I have installed should not occupy more than 10-15GB. So there are still about 25-30gb of unknown files that are swallowing up my phone's storage. How can I find the files that take all the rest of the storage? Also, my internal disk space should be 64GB but windows says I only have 51.3GB which tells me that windows somewhat cannot see everything on my phone.

I bought Samsung J2 prime phone. Some details of that phone as follows. Model - SM -G532G Android version - 6.0.1 I heard that earlier it came with good feature that allow us to format external SD card as internal storage. I tried to format my new SD card as internal storage. But it does not give that option in my phone. Is there anyone who has similar experience to solve this problem? Thanks

I have an Android Voyager, RCT6773W22B. It's version 5.0. When I first got it, and years after that, I could download at least five apps downloaded at a time and have a great sum of pictures in my gallery. I would still have space after this. Over time, I would delete apps I didn't use anymore. If I wanted to download something else and there wasn't enough space, I would delete apps and/or pictures I don't need. Now, I can't download anything due to internal storage. I have no apps, five pictures (not taken with the camera), and I've cleared the cache on everything except Chrome. It tells me my internal storage is completely full and I can't move anything to an SD card. What do I do?

In my Samsung Galaxy S9, WhatsApp is showing that it uses 37.89GB of internal storage when I checked the app info. Due to that, my phone's data is getting full and all the other apps are getting hung due to less storage space left in my mobile phone. When I checked the WhatsApp 'Settings' -> 'Data and storage usage' it shows only 195.1MB of data has been stored for WhatsApp. From where the 37.89GB of data is being shown in the app info on my phone? **Please note:** I don't want to delete my WhatsApp and reinstall it to fix this issue because I don't want to lose my WhatsApp messages, and I can't take the backup also because there is no more space left on my mobile to take the backup.

I'd like to delete some files on my Android device (Xiaomi) by deleting files stored by WhatsApp that I didn't save in my gallery. I have a few questions. 1) If I understand correctly, whenever I send a media by WhatsApp (being it a video recorded in the app or a video/picture already existing in my gallery) it creates a copy of the media in the following folder. Is it correct? Internal memory\Android\media\com.whatsapp\WhatsApp\Media\WhatsApp Video\Sent Internal memory\Android\media\com.whatsapp\WhatsApp\Media\WhatsApp Images\Sent 2) If I delete those media (even if they were originally in my gallery), will I delete them also from the gallery or only from that folder? 3) I see that in my gallery I have some media from Internal memory\Android\media\com.whatsapp\WhatsApp\Media\WhatsApp Video. These are the media I received by WhatsApp and I saved in my gallery (be default or explicitly). Is it correct? In this case, if I delete them, I would delete them also in my gallery (meaning I won't have them anymore on my device).
