Problem #1: How to fix Galaxy S9 Plus texting issue: can’t schedule sending of text messages

Hello. I recently upgraded to the Samsung S9 Plus, I previously had the S5. In the s5 I was able to set a delay for sending text messages that was up to 30 seconds long. I cannot find that delay on the S9 Plus. however I do see where i can schedule a text time (not really the same thing). I really liked the delay and it helps a lot so I don’t accidentally send something to the wrong person.

Solution: If you’re using the Samsung Messages app, you can use its Schedule message option to delay sending of your message later. Such feature may not be available for non-Samsung text messaging apps. The feature also depends whether or not your carrier’s firmware support it. If you’re using Samsung Messages, follow the steps below to use Schedule messages:

Open Samsung Messages app (may only be named Messages in some devices).
Start a new chat, conversation, or open a thread to reply.
Tap the More settings option at the upper right.
Tap Schedule message.
Set up your preferred date and time for sending.
Hit Done afterwards.

If your Galaxy S9 Plus was provided by your carrier or part of your contract with them, you can seek their help in getting first hand information about the missing feature. It’s possible that they may have removed the stock Samsung Messages app and replaced it with their own, which has this missing feature. Again, an issue like yours is app-specific so the answer depends whether or not the text messaging app you’re using supports it.

Problem #2: Galaxy S9 Plus restarts on its own after an update

Samsung S9 Plus shuts downs on it own since OREO update. Was sporadic initially but now happens within 30 seconds of turn on. Same issues with the phone in safe mode. Slight delay if in an active applications no pattern to which app just has to be actively in use example open contacts so long as you scroll system stays up but if left on same screen phone will shut down.

Solution: Without a full background of your device, there’s no way that we can tell where the problem may lie. If the phone has suffered physical damage prior to updating it, it’s possible that the update may just be a coincidence and the real reason may be hardware malfunction. If your S9 Plus is taken care of and has not been physically impacted or exposed to water, liquid, or elements, then there’s a good chance that the reason for the current situation is being caused by a firmware glitch. In this case, you want to do two basic software troubleshooting steps: cache partition wipe and factory reset. Below are the steps to do them.

How to clear the cache partition of a Galaxy S9 Plus

Cache partition wipe is often helpful in cases wherein a device has encountered bugs or performance issues following an update. Here’s how it’s done:

Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key to highlight “wipe cache partition.”
Press the Power key to select.
Press the Volume down key to highlight “yes” and press the Power key to select.
When the wipe cache partition is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

How to factory reset your Galaxy S9 Plus

Should the phone continue to lag, freeze or display the same problem, you should return all its software information to their defaults. Be sure to back your personal data first before doing a reset.

From the Home screen, swipe up on an empty spot to open the Apps tray.
Tap Settings > Cloud and accounts > Backup and restore.
Tap the following sliders to desired setting:
- Back up my data
- Automatic restore
Tap the Back key (bottom right) until you reach the main Settings menu.
Tap General Management > Reset > Factory data reset.
Scroll to the bottom of the screen, then tap RESET > DELETE ALL.
If you have screen lock turned on, enter your credentials.
If prompted to verify your Samsung account, enter the password, then tap CONFIRM.
Wait for the device to reset.

Once you’ve factory reset the device, let it run for a few hours without any third party app. This should help you tell if there’s a difference in performance. If everything appears normal and the issue won’t return, then the cause is probably a bug with the firmware, which the reset has eliminated.

Problem #3: Galaxy S9 Plus files are corrupted when transferred to SD card

Samsung Galaxy S9 Plus corrupting picture and video files. Multiple QA tests done on Factory clean system with verified SD card and rebooting with wiped cache in between tests. Updated with latest system update.

Files can corrupt on the internal drive.
Photos created on Pro setting (with default settings) corrupt more frequently than photos using auto setting.
Files moving to verified good SD card in bulk will corrupt, all pro and many of the auto jobs, all videos
If any app is running in background, moving files to SD card will corrupt.
When COPYING photos and/or video files, in bulk or with an app running in background, photos will corrupt on SD card AND on internal drive.

Do you have any suggestions on how to keep files from corrupting? Apparently, it corrupts something in the header – do have any suggestions on an app or process to fix the files?

Since moving or copying the files corrupts them, and saving to cloud is NOT an option (we have security issues) , we have been able to retrieve the uncorrupted files via sending thru a secure email account, but we can’t send the videos — too large.

Do you have any other suggestions on transferring the files off of the devices? Have you heard from Samsung directly on this Very common recurring problem? Thanks for feedback.

Solution: It’s our first time to encounter this particular issue so the only logical reason that we can think of is that it may be caused by a firmware bug. What that particular bug and whether or not there’s a fix for it on your level is unknown. There’s too many variables in this case so identifying the bug is impossible. What you want to do now is to perform a master reset to see if it continues after that. If it does, you can then go ahead and ask for a replacement unit from Samsung or your carrier.

For your secondary concern, the only suggestion we have for you is to try file transfer apps like Samsung Smart Switch or third party ones like ShareIt. Both of these apps can be installed in another smartphone to allow wireless transfer or large files.
