Problem #1: Galaxy S5 SD card questions

Lost my original 16 GB S5 in Jan 16, and when I received replacement from Insurer, I “restored” pics, videos, songs, Contacts and Messages from Verizon “Cloud” totaling about 9 GB to new phone. Then moved all Pics, Videos, songs, and some Apps from Internal Storage to new 64 GB Samsung SD card which I installed. I then reinstalled apps onto phone internal storage from “My Apps” on Google Play.

All worked fine until July 20th. Then 64 GB SD card showed as “corrupted.” At that time I had about 9 GB of pics etc. on SD Card PLUS about 40 Apps that I had transferred from device storage after I “restored” and transferred Pics, etc. to new SD as set forth above.

In lieu of trying to immediately recover or repair corrupted 64 GB SD card, I decided to purchase new bigger and faster Samsung 128 GB micro SDXC PRO+ UHS-1 card with 95/90 NB speeds. 

Phone currently has about 1.1 GB internal memory available.



  • When installing this new SD Card, “should” I format it before loading anything on to it?
  • Since I do not have enough internal memory to “restore” 3 GB of Photos or 4 GB of songs from Verizon Cloud backup space, how, if possible, can I directly “restore” these items to new SD card without first restoring to internal memory and then transferring them over to SD card?


  1. If no direct way, is there a way to download pics and songs from Verizon Cloud to computer and then directly to SD Card?
  2. Any other solution to get pics and songs directly onto SD card without deleting or moving enough stuff off internal phone memory to create 3 or 4 GB of available space in internal memory?


  • How to repair or restore old 64 GB SD card; or to get whatever was on it off in form that could reinstall on new 128 GB SD card if I wanted to?


Please send a copy of these questions to me.

Thanks. — John

Solution: Hi John. First of all, we don’t work for Verizon and thus, don’t have first-hand knowledge of how their products work. Please direct your Verizon Cloud questions to their technical support team for effective answers.

When installing this new SD Card, “should” I format it before loading anything on to it? Some SD cards come formatted out of the box but it’s highly recommended that a user should format it using the device it’s supposed to work with to minimize bugs.

How to repair or restore old 64 GB SD card; or to get whatever was on it off in form that could reinstall on new 128 GB SD card if I wanted to?

SD card capacity does not matter in file recovery. The amount of files that can be saved from a malfunctioning SD card depends on how bad the storage medium has been corrupted. Special software from third party services are often the only way one can use to recover files. Windows computers or Samsung devices don’t have the necessary application to do file recovery task so you’re out of luck. The only thing that you can do is to hope that inserting your SD card to another device like another smartphone or card reader can still detect some files. This way you can extract the remaining files and save them. Keep in mind that even third party special programs will not be able to recover badly corrupted files.

Problem #2: How to downgrade Galaxy S5 from Marshmallow to Lollipop | Galaxy S5 randomly rebooting after Marshmallow update

Hello. I bought a Samsung Galaxy S5 mobile phone without any locks in Switzerland. It worked always fantastic. No problems. Recently, after the Operating System Update from 5 to 6 my phone started to reboot randomly.

So I went to the internet and checked possible solutions. These were:

– Try to reduce amount of apps

– Try to use it in recovery mode

– Try to factory reset

Nothing worked. The phone still rebooted randomly.

How did I solve the problem?

I started to look for a custom ROM. So I found a nice video on the internet. I did exactly what he said, from the beginning to the end.

After that I had a custom ROM on my smartphone. Since then no more problems, no more reboots. It’s important that you disable all the Auto-Updates. Google Play Auto-Updates (Google Play>settings) as well as the other updates under Android>settings>About device and Settings>security.

In case you installed your new custom rom and messed it up with the update. You have the problem of the notification “software update postponed”. How to get rid of it?

Factory Reset works just fine. Do it again, disable everything fast enough and you don’t waste storage, etc.

What else you need to do?

 – your mobile data will not work, even though your mobile data is activated in the android menu. To fix that you have to call your phone provider and ask for details. They will tell you some information you have to type in under Settings>More networks, APN (Access Point Names). — Mrvision

Problem #3: Galaxy S5 restarts on its own when using Snapchat

It started a couple weeks ago. I wanted to open snap chat but my phone immediately turned off. I had to turn it on and it was fine, as long as I didn’t open up Snapchat again.

From them on, it was a hit and miss. Sometimes Snapchat would make my phone shut down, other times it wouldn’t. Until yesterday. Every time I opened snap chat my phone shut down. Unless my phone was plugged in to the charger, if it was hooked up to charger it was fine, the app worked fine. Then the problem moved on to everytime I opened the app my phone wouldn’t just shut off, it would continuously turn on and off. It wouldn’t ever completely turn on. Not even taking the battery off for a couple minutes worked.. as soon as I turned on the phone it would vibrate, light up like it was going to turn on, turn black, vibrate, light up and so on. That would not stop until I hooked it up to my charger. I let it Charge for a bit, unhook it and the phone would work fine again! As long as I didn’t turn on snapchat. Well NOW -_- it will continuously just turn off and on again by itself if I even unhook it from the charger without any apps open.. and my battery is at 100%. I tried clearing cache for snap chat and that did nothing… what do I do??? What’s wrong with it?? — Glenda

Solution: Hi Glenda. Snapchat causing all sorts of problems is well documented in many other Android blogs so this issue is no longer a surprise to us. The real issue is that Snapchat support team is as helpless as we are. A lot of Android users continue to report issues like yours everyday without getting official guidance from Snapchat. Solutions up to this point vary from case to case so there’s really nothing much that we can do for you. Frankly, your problem is best addressed to Snapchat support team than us. The troubleshooting and potential solutions that you can do on your end is very limited, including full uninstallation of the said app. We doubt basic troubleshooting will help in this case but it won’t hurt if you try them nonetheless.

The first thing that you want to try is to wipe the phone’s system cache. This will force your phone to create a new system cache, just in case the old one was corrupted. Here’s how to do it:

This troubleshooting step is usually recommended if you have updated a device to another operating system version or if the phone is having some weird glitches. Despite not having installed the full set of new operating system files, we suggest the you do the following steps to erase possibly corrupted cache on your device:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.

If nothing changes after wiping the cache partition, don’t hesitate to do a factory reset. Here’s how:

  • Power down the Galaxy S5.
  • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
  • Use Volume down to highlight the wipe data/factory reset option and press the Power button to select it.
  • Use Volume down again to highlight Yes – delete all user data and press Power to select it.
  • Use the Power button to select Reboot system now.
  • When the S5 restarts it should be completely wiped and ready to set up again.

Again, if there’s no positive result after you do both of these procedures, make sure that you contact Snapchat developer team for first hand support.

Problem #4: Galaxy S5 mobile data not working on Net10 network

Bought a refurbished from factory Samsung Galaxy S5 4G LTE. Phone worked perfectly with great signal and all until it told me it had the firmware update. It downloaded (I thought with no issues) but soon after I realized I was not receiving any phone calls. I then tried to place a call and it would never go through. phone would time out with NO error message! Tried to change APN info and that didn’t work. Then I read somewhere to check the network type. for some reason it was on CDMA. Changed it and it allowed calls to come through but still shows mobile network state disconnected. called Net10 and they said all was good on their side. I placed SIM back in my old phone (LG G3 D690 Stylus….duos SIM version) and it works fine. Put back in galaxy and same issues. Now it has no data working.

Things I’ve done to try and troubleshoot is changed APN…went back to default when told by Net10 to do so, toggled airplane mode, took out battery and restarted phone, did a hard reset, cleared phone cache and switched to GSM only…which is only way phone now calls, but still no data and signal very weak.

I may have also tried to go in safe mode thinking and APP could be the cause but no luck. PLEASE HELP! Antenna seems to be working!? Phone not rooted or anything either. IMEI number looks correct in phone other than showing a blank space and 19 or 20 after first initial numbers. Unsure of why. they are not showing on back of phone under battery. I’m lost at this point! Net10 says it’s a phone issue not network! IDK? LOST PLEASE HELP! — Ron

Solution: Hi Ron. Net10 Wireless supports both GSM and CDMA phones so it’s interesting to know that mobile data on your phone does now work as expected. Net10’s technical support must be right, that the issue is with your phone, probably a bad cellular radio. If wiping the cache partition and hard reset did not change anything, you can safely assume that the phone’s mobile data functionality is not working properly due to a hardware malfunction. Consider having the phone replaced to continue using Net10 services.

Problem #5: How to prevent OTA update notification on Galaxy S5

I had been given this phone from a repair shop as a replacement for my last one. I don’t think they had done a factory reset before giving it to me, seeing as it didn’t take me through the initial phone set-up. I knew the software was probably going to be outdated so I checked for a new one and immediately installed it. The installation went just fine, and there were a couple more after the first, each one getting more current. Now it’s finally at Lollipop 5.1.1 however it’s still coming up with system update prompts. Every single time I go to install the update it first asks to restart. Then it says it’s initializing (or processing, I don’t remember) app 1 of ‘x’ (I can’t remember the number off the top of my head). It’ll go all the way through the apps and then come to a loading screen with a percentage. It goes all the way through that then finally turns back on. It’ll say that the software update was complete but it’ll come back with another one a couple of hours later for the exact same update. I went through it maybe 2 or 3 times before I started to think this was an ongoing problem. I’m really trying to avoid a factory reset because I seriously hate having to back up all of my things, so I’m wondering if there’s any way to troubleshoot it and get it to quit updating every 3 hours. Or should I just take it back to the repair shop and tell them to fix it? I hadn’t installed any apps when it started doing this. — Kaley

Solution: Hi Kaley. Preventing OTA (over-the-air) update notifications is usually determined by your phone and its carrier settings. Some carriers disable the option to turn this off so the answer to your query depends on your phone right now. For Galaxy S5s meant to be sold in other countries, the option to prevent Android system update notification can be found by going under Settings>About device>system update. If this option is nowhere to be found on your phone, you’re out of luck. Consider having the current phone replaced, or have it factory reset first so you’ll know the difference.
