Problem #1: Galaxy S7 reboots when connected to mobile data and near home vicinity

Ok. So this is a bit different from most of your rebooting problems i see. so my phone keeps rebooting, BUT only when I’m at home or near my house. if i am at home and have it on airplane mode and wifi it doesn’t reboot. if I’m more than a few miles from my house it doesn’t reboot. i had this issue and T-Mobile gave me a warranty replacement and as soon as i restored the new device it started doing it again. But like i said, only at home and only if I’m using cell data. T-Mobile thinks it’s hardware, Samsung thinks its software. Had it re-flashed at Best Buy and also wiped my partition cache. Still does it. Any ideas? — Nataliyacurtis

Solution: Hi Nataliyacurtis. This is a curious case for us but one thing that you did not mention, after you said T-Mobile gave you a replacement unit and after Best Buy reflashed it, is the set of apps that you installed. That the issue still occurs on a different unit seems to us a sign that the problem may be on third party apps on your device. To check, perform a master reset (we prefer this over booting to safe mode as it can ensure that software settings are restored to their default state), and observe the phone when at home for at least 24 hours. Make sure that you don’t install anything during this period. If the problem won’t happen at this time, you must go over your list of apps and try to identify which of them is causing this issue.

For reference, these are the steps on how to factory reset your S7:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Problem #2: Galaxy S7 email app inserting first letter when typing | Cannot type complete URL when typing on Galaxy S7 email app

I have suddenly devolved an issue when entering text in email. When I go to spell a word but if I spell it incorrectly and delete all but the first letter, when I go to re-spell the word it inserts the first letter again; WWord; HHello; AAndroid, etc.

Another issue is when I input Web addresses (again in email). If I want to put www.android.com it only lets me put www. because no matter what I try to insert next always changes to a. (So it ends up being www……; I cannot put any more text/numbers in after the www).

And another issue…in email. When I insert a bracket like so ( and then start typing, the first thing I type turns into another bracket…like this ((…no matter how I try to sort it. I am using the stock email app that comes as default with the Samsung S7. It is driving me crazy. — Phil

Solution: Hi Phil. The first thing that you can try is to wipe the system cache. Sometimes, app or system updates can corrupt the system cache, resulting to erratic behaviors of some apps. Wiping the cache partition may be the easy fix. Here’s how:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.
  • Check how the email app works again.

If wiping the system cache won’t help, delete the email app’s cache and data:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, find the email app and tap it.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #3: Galaxy S7 unable to transfer files to Mac via Android File Transfer

read every forum known to man. Looked every where. I have model number SM-G935A S7 Edge. Using a MacBook Pro with iOS El Capitan 10.11.6. Android File Transfer opens when I connect my phone but always says unable to connect reconnect device or restart. In debug mode, I enabled MTP, used countless cords — nothing. I really want AFT to work because it’s so easy and do not want to use Dropbox or Google photos or anything to transfer my photos WANT to connect. Iphoto connects but as soon as it starts transferring, my phone says MTP interrupted and stops the transfer. I’m at my wits end and am about to take my beloved Edge back and just get an iPhone which I really don’t want to do. I have read all the forums and everyone keeps giving simple fixes of which none of them work.. PLEASE HELP. — Matthew

Solution: Hi Matthew. First of all, we want to make it clear that before you blame everything on your Galaxy phone, there’s just the same level of likelihood that the real issue is due to your Mac. Make sure that you troubleshoot your computer first before attempting another file transfer. That said, you must contact Apple or any relevant party to help you ensure that your computer has all the necessary drivers to communicate with your Samsung phone. This is not within our scope of support so find another site or forum site that can help.

Secondly, you can try to troubleshoot your S7 but if only to check if software is to blame for the constant disconnection. Consider doing all the procedures (like wiping the cache partition, booting in safe mode, or factory reset) in this post to check. If nothing change, try another computer to move files to.

Problem #4: Cannot access Galaxy S7 Edge home screen edit mode

Hello dear, good day. i am facing a serious problem. i will be glad if you assist me in my problem.

Please help. Thank you very much. — Iftikhar

Solution: Hi Iftikhar. We’re not sure if we understand your concern very well but we assume you’re having difficulty accessing the Galaxy S7 home screen edit mode. Normally, you can go to home screen edit mode by either tapping and holding any blank space on the home screen, or by pinching (moving two fingers inward). If these both of these means to access edit mode is no longer recognized by your device, it’s probably due to a glitch. Try to boot the phone in safe mode and see if it will do anything. Here’s how:

  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • Try to check again if you can now access home screen edit mode.

If the problem is still there, do a factory reset.

Problem #5: Galaxy S7 Edge stuck in “error has occurred…” screen

Good day. I have this phone for like 5 months. A Samsung S7 Edge. It was bought in Europe and since the phone was offline in my location i took it to Samsung store and i guess by opening the line they rooted my phone because I can’t download any software update. Then just yesterday I restarted my phone due to its slow performance. But I got stuck in the Samsung logo. Volume down+home+power button do work but only to restart the phone again. I tried volume down and power button nothing happens. So i took it to a technician saying that my phone has to be reprogrammed for it to work again. I authorized him to do it. Then after that he returned my phone stuck in an error has occurred screen. He says that my phone’s MMC (multimediacard) was broken and I had to either sell the phone because it would be difficult to look for its parts. 🙁

Is my phone really broken? Or the technician accidentally bricked my phone? He even says that his program would not cause such things because it is just a program and no parts of the phone has been touched or replaced. Please help. Thank you. — Jhomel

Solution: Hi Jhomel. The only one who can answer your question is someone who has verified the hardware. It’s possible that the physical memory chip has been corrupted by whatever software modifications you, Samsung, or the technician has performed, but more advanced procedures must be done to confirm it. Try to bring the phone to another repair shop so they check the phone and give you a second opinion.

Also, if you haven’t yet, make sure that you try a cache partition wipe and/or master reset just to see what happens.

Problem #6: T-Mobile Galaxy S7 cellular and mobile data signal disappears during calls

When I am talking on the phone, no matter who I am talking to or where I am, after talking for a couple of minutes my phone will show that I have no signal. The call still continues just fine, but I cannot do anything else on my phone that requires service (sending/receiving texts, going on the internet, etc). Also, when I am talking on the phone and I put it on speaker phone, the person that I am talking to says that I am cutting out, but when I put it back to the regular phone, they have no issues hearing me. This also happens regardless of where I am or who I’m talking to. I have tried a soft reset on the phone and it doesn’t seem to change. I always close out of apps after I’m done with them. I’m from T-Mobile. Help! — Meghan

Solution: Hi Meghan. You must do a few trial-and-error troubleshooting to isolate where the issue lies. To know if the problem is hardware-related or not, you must do all the software troubleshooting we mention in this article. As the general in Android troubleshooting, if all software troubleshooting fails, you can assume it’s a hardware issue. Contact Samsung or any relevant party to have the phone checked for hardware issues or unit replacement.

Also, make sure that you install all Android and app updates that are available. If the issue is related to a bad baseband version, updating the it (via the regular over-the-air update) may help. Keep in mind, as long the issue is being caused by some app/s in your phone, the software troubleshooting like factory reset should fix it. However, if the cause of issue is entirely beyond your control, like a buggy operating system from your carrier, or something from the network side, the problem may keep occurring even if you’ll ask for replacement phone. We do recommend that you still call T-Mobile though so they can take note of your issue.
