I've got a bit of a bizarre problem with my Android phone: My internet connection is working and fully functional, since Chrome and most other apps have no problems. However, some apps do not detect an internet connection. They display 'No internet connection' errors or similar. Some apps do this far more frequently than others, and some can reconnect randomly. Here are some observations: - My banking app does this almost every time I want to check it. - Various messaging apps will receive messages hours late (sometimes). - This issue is temporarily resolved on reboot, and for some time all apps can connect to the internet. - Terminating a process and relaunching it does not let it reconnect to the internet. - Some apps can be using the internet just fine at the same time that others are not. - Some apps never do this, such as Chrome, Google, various games and others. As far as I can tell, it has existed since I got the phone a few months ago. I've tried disabling Samsung's battery manager in case it is messing with apps to save power. I'm currently running my phone in safe mode - but it's unclear if this has had any effect yet. I'm on WiFi, and I don't use mobile data. I own a VPN app but it's almost never enabled (except when traveling). The VPN app is one of the badly affected apps. Other devices on the same WiFi network do not show similar issues, and this problem occurs on any WiFi network. Any advice on how to fix or troubleshoot this issue would be appreciated.

I have just received a video from a customer, via Whatsapp, and I'd like to download it. There was no automatic download, configured on my Whatsapp, and now, even after having configured it, this has not performed the download. The video is quite large, and forwarding it to mail or teams is also not an option. When I start the "Samsung My Files" app, I arrive inside some subdirectory I can't get out of. So, basically: 1. How can I download a video from a Whatsapp on my smartphone? 2. When downloaded on my smartphone, where is it? 3. When plugging my smartphone into my PC, I don't see my smartphone. How to configure that? I'm working with a Samsung Galaxy A51 Thanks in advance

I cannot get apps enabled or disabled using ADB. - Android: 8.0.0 - Device: Samsung Galaxy A520 (SM-A520F) I don't have root access to my device. To get the list of the disabled packages I use: $ adb shell pm list packages -d package:com.samsung.android.game.gamehome package:com.microsoft.skydrive package:com.google.android.webview package:com.google.android.videos package:flipboard.boxer.app package:com.samsung.android.ststub package:com.sec.android.emergencylauncher package:com.samsung.android.dlp.service package:com.samsung.upsmtheme Q1: Oddly, this list doesn't seem to include the apps I really disabled in the Apps section: - Briefing - Google Play Movies & TV Why is that? Then I run through the list and enable every package, e.g.: $ adb shell pm enable com.google.android.webview Package com.google.android.webview new state: enabled Q2: Despite some packages are reported as "enabled" they are still in the disabled list: $ adb shell pm list packages -d | grep com.google.android.webview package:com.google.android.webview Why is that? Q3: How can I get the list of packages that I myself disabled in the Apps section and how can I manage this list using ADB?

i'm wondering how to tell the difference between a Samsung Galaxy A5 2017 flashed with something like XEU or one with BTU. That is if it's already installed and if I don't know what type it is. Any answers are appreciated. Thanks.

Ever since I bought my Samsung Galaxy A5 (2017), I've been using its Always-On Display feature, which displays a clock or calendar with unread notification icons, or one of four preinstalled images on the screen while it's in the "off" state (e.g. locked).  I'm using the Image option as you can see on the screenshot above. I've heard recently that Samsung phones are notorious for being susceptible to screen burn-in because of their AMOLED displays. Is that something I should be concerned about when using the Always-On Display feature?

I have been doing a lot of hobbyist electronics recently and was wondering if I can use my old Samsung Galaxy A5 duos phone, samsung galaxy core duos gt-i8262 and/or Samsung Galaxy Tab 4 7.0 3G in some of my projects. I don't have a lot of knowledge on android and was hoping I could skip having to learn android development, I was wondering if I can install a linux distro (like ubuntu touch) on these devices to simplify things, but my research so far heavily implies that's a no. What I basically want to achieve is as follows: - Use aforementioned devices (and their peripherals like camera, accelorometer etc) in my projects, running programs in a familiar language (like c/c++ or python), in a close-to-linux environment - If i can't use the peripherals, at the very least, I want to use the CPUs on these devices to execute a program - Preferrably, not use android or at least not a heavy OS to dedicate as much CPU and RAM to my programs as possible - These devices would be controlling other electronics of the project using a microcontroller such as arduino - To summarise, I want to get these devices to work as much like a raspberry pi board as possible (excluding the GPIO pins part) What I think are my options: - Building a linux kernel for these devices - Building a custom version of android for these devices - Just using the version of android these already have on them and somehow working on that To top it off, the catch with the Tab device is that it won't boot beyond the samsung logo screen, so I'm not sure if I can get around having to install some new OS onto it anyway. I know that phone manufacturers make it a lot harder for tinkering with the innards of their devices, so is it possible to have these functionalities on these devices? And are these the only options or is there a better way to go about doing this? Any help would be great. Thanks.

The screen on my Galaxy A6 is dead. Until I possibly get it repaired, I would like to shutdown the phone, mainly to stop the alarm which I cannot turn off without the screen. I have seen plenty of instructions on how to force it to reboot (power + vol. down), and on how to hard reset it. But that is not what I want. I just want to turn the phone off. (it would be easy if I could remove the battery, but that is not possible either, and I didn't think of checking that before buying that thing...)

I have been reading numerous articles on this, but nothing seems to work for me. I have a Galaxy A5 (2017) running on Android 6.0.1. When I plug it into my Ubuntu 14.04 laptop, the phone is recognised and I can browse the folders and see files. However, I cannot open any of the files, nor can I copy anything to the phone. When I first plug it in, this is the dmesg output:

[ 2168.258890] usb 2-1: new high-speed USB device number 9 using xhci_hcd
[ 2168.276856] usb 2-1: New USB device found, idVendor=04e8, idProduct=6860
[ 2168.276860] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2168.276862] usb 2-1: Product: SAMSUNG_Android
[ 2168.276863] usb 2-1: Manufacturer: SAMSUNG
[ 2168.276864] usb 2-1: SerialNumber: d31e7ed99d31e7ed

At this point, "SAMSUNG Android" shows up in Nautilus, with nothing in it. The phone then asks me if I want to allow the connection, which I do. Then dmesg displays the following additional output:

[ 2190.116385] usb 2-1: USB disconnect, device number 9
[ 2190.417923] usb 2-1: new high-speed USB device number 10 using xhci_hcd

Another Nautilus window pops up and the contents of the SAMSUNG Android device now contain "Phone". When I open that, it displays the directory structure. Like I said, I can browse through it, but not actually read the files or copy anything to it. The "Use USB for" setting on the phone is set to "Transferring media files"; "Transfer media files to a PC via an MTP connection.". When I change this to "Transferring images"; "Transfer images and other files via a PTP connection if MTP is not supported.", then I can open images on the phone, but I am restricted to only directories containing images. Any ideas?

I lost some notes from the app Samsung Notes and I think I know why or at least how to reproduce the event. This happens when the phone has no space left (0 free bytes). When whatsapp app makes a backup at 2am, it eats a lot of space and then a few minutes later it comes back to normal. When I click in a note to open it while the phone has 0 free bytes, the note doesn't open anymore (message: "Can't open note. File corrupt"). It also doesn't let me share it anymore or convert it to pdf or text (message: "File corrupt or not supported). The phone is a Samsung Galaxy A5. I'd like to know if the notes are really lost forever or there is something I could do. Thanks.

I cannot add Google account to my Galaxy A5. I input email and password correctly, agree terms. Then the circle spins and nothing happens, account is not added. I cannot sign in to any Google stuff such as Gmail as well due to the same reason. I tried clearing cache of Google Play services but no help.

As per the title, I used to have an Android (v5) where I would copy some text once, and keep pasting to wherever; On my new phone (Android v10 - Samsung Galaxy A51), clipboard text disappears after a paste; Is there a setting to allow retaining last copied text ? [cannot create samsung-galaxy-a51 so using samsung-galaxy-a5 instead]

 I can not turn on HDR. It is grayed out. I tried all modes front and rear camera and it is always Grayed out and I cant turn It on. I am using a Samsung Galaxy A50 that I recently bought and Samsung live chat support was not helpful. I am on the latest software.

I use Samsung Galaxy A5 (2015) and I have just upgraded the firmware to Android 6.0 (Marshmallow). The phone supports 3G but the option to set it is LTE/3G/2G (auto connect) on Network mode. How do I get the phone to use 3G only?

I use Samsung Galaxy A5(2016) and have just upgraded the firmware to Android 6.0 (Mashmallow). The phone supports 4G but the option to set it there is LTE/3G/2G (auto connect) on Network mode. How do I get the phone to use 4G only? **P.S.** I have tried *#0011# and have entered Q0000 as answered here but it is not working.

Straight to the question: ------------------------- To solve the issue I think I have two options: 1. I read on XDA that the 4 files firmwares (service repair firmwares) are needed to fix the phone, but I couldn't find that type of firmware for my model, anyone has any idea how to get those? 2. Downgrade: I'm on build 6 and there is only one update for build 6 released, that means I can't downgrade my phone to anything. I'd really like to fowngrade to build 5 firmwares, any way around this? Long story: ---------- I use my phone very normally, minimal apps, no custom ROM and no root etc. My phone is in very good condition, no damages, no drops, protective case and screen protector (I take good care of it). I was watching YouTube then Wi-Fi suddenly disconnected and it just doesn't turn back on, the circle-status-bar icon just keeps rotating right next to the Wi-Fi toggle switch and it says: "Turning Wi-Fi On" (or similar, my phone is not in English). When I reboot the phone, the wifi state is on (though it's not on) switching Airplane mode does not change Wi-Fi state. Toggling Wi-Fi icon from Quick Lunch menu (Notification Menu) switches the on state of Wi-Fi to off, toggling again, switches it to the "Turning Wi-Fi on" mode. Here's what I've tried so far with no avail: 1. Rebooting phone a couple of times. 2. Resetting network settings (+resetting both sim-cards networks) 3. Resetting all settings. 4. Booting into stock recovery and wiping cache. 5. Backing up my data, removing all accounts (to prevent anti-theft lock-down), booting into stock recovery and wiping data (factory reset). 6. I tried adb shell, dmesg and I searched for "wifi" in the output, here's the result: Line 125: [ 1407.084890] I[0:WifiStateMachin: 5871] mif: LNK-TX(16): fc eb 0b 00 07 00 1b 00 0a 50 02 01 c0 ff ff ff Line 347: [ 1445.061702] [0: mc_log: 2225] MobiCore mcd: d01|TZ DB Utils: Wifi UID: 1010 Per user range: 100000 System UID: 1000 Line 518: [ 1447.799328] [3: mc_log: 2225] MobiCore mcd: d01|TZ DB Utils: Wifi UID: 1010 Per user range: 100000 System UID: 1000 7. Redid number 5, but this time I removed SD card and both sim cards before factory reset. 8. A website suggested to have all Wi-Fi devices turned off, I turned off my router. 9. Tried a soft-reset on my phone in those first steps that I forgot to mention, a website said that it is the equivalent of removing the battery and re-plugging it for non-removable battery phones. 10. I watched this video: https://www.youtube.com/watch?v=F2K6AhkN98Y and since I never use bluetooth, I never checked but now I did and it turns out, bluetooth doesn't turn on as well... hardware problem? When I toggle the BT switch, the toggle moves but doesn't change to blue color, when I press back to previous window then go back to BT setting window, the toggle is off. 11. My phone already had the latest firmware, so I downloaded the same (latest) firmware from sammobile.com and flashed with AP mode from Odin 3.12.3 and I wiped cache and data (factory reset) from stock recovery. 12. Turning BT on from *#7353# (Quick Test Menu) just shows" Bluetooth is being turned on Please Wait..." and it just hangs there. 13. Installed TWRP with Odin, and installed a custom ROM https://forum.xda-developers.com/samsung-a-series/development/rom-resurrection-remix-rr-v6-unofficial-t3765542 with TWRP. Wi-Fi doesn't want to turn on. 14. I even tried this custom ROM https://forum.xda-developers.com/samsung-a-series/development/rom-advanced-seven-v1-3-t3516980 it still didn't work. ---------- Sources for my troubleshoots: https://thedroidguy.com/2018/08/fix-samsung-galaxy-a5-2017-can-no-longer-connect-wi-fi-troubleshooting-guide-1074378 https://www.technobezz.com/turn-wifi-on-wont-android-samsung/ https://www.ifixit.com/Answers/View/321336/Cannot+%22Turn+ON%22+Wifi+and+Bluetooth . https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin https://www.youtube.com/watch?v=m3hXULbrCYc

"Galaxy Apps", the package manager for the bloatware pre-installed apps on my Samsung Galaxy A5 (2017), requires access to my contacts. In fact, it plain out refuses to run as long as I don't give it access: Why does it need them? (I decided to grant access, since I don't want any security risks due to outdated apps, but I'm still curious.)

Nothing happens when I plug a USB stick to my Samsung A3 2015 (SM-A300FU) with an OTG cable (on-the-go). **How to enable OTG support on this device?** *PS: I previously had a 5.0.2 original, unrooted. I now have a rooted 6.0.1 Marshmallow (Build number MMB29M.A300FUXXU1CRA3, Kernel version 3.10.49-12877970, Fri Jan 12 20:48:03 KST 2018).*

I apologize if I did not formulate the question correctly however I'm a 'noob' regarding Android versioning and Android ROM software etc. Here is some background regarding my question. I bought a 'not simlocked' phone from a retailer here in the Netherlands. With the intention to buy a sim only subscription from a network carrier as this was 50 euro's cheaper. Note that the network operator is also Dutch. On the website of the network operator it shows that the Samsung Galaxy A5 2017 supports Wifi calling at that provider. However I do not see WiFi calling in the options. I suspect this is because the CSC on my retail Samsung Galaxy A5 2017 is not the same as a Samsung Galaxy A5 2017 bought at Tele2. The Samsung helpdesk of my country says it should be possible if you insert a Tele2 simcard. My question is, is it possible for me to change the CSC of my android phone to that of the CSC of Tele2/My network carrier as I would like to use WiFi calling. Inserting the Tele2 simcard does not change anything with the software.

I have an old Samsung galaxy a5 2016 (sm-a510f). I had previously rooted it and installed a custom ROM called the Google Product Rom along which came a boot animation that flashed the google logo before actually going into the animation. Now I have decided to unroot the phone and flash the stock firmware, I have managed to do everything including getting rid of the boot animation. But when I boot up the phone it still flashes the Google logo before going on to play the Samsung boot animation. How do I get rid of it without having to re-root my phone? If there is no way and I have to root my phone again! How do I achieve this on a rooted device?

I use Samsung Galaxy A5 (2017) with Secure Folder. So far I need to add extra language (English is primary one) Android starts to download but nothing is downloading under super-fast WiFi. I am sure this is a Secure Folder issue. Any clue?
