Sprint Galaxy S2 (Epic 4G Touch) Problems, Errors, Questions, and Solutions

galaxy s2

This is the first of the many parts of our Sprint Galaxy S2 Problems series as we have received a lot of emails from our readers who happened to own an S2 under the umbrella of Sprint in the United States. By the way, Galaxy S2 is also called Epic 4G Touch when in Sprint and it has different names in other carriers, so don’t be confused. To further avoid the confusion, I will address this device as “Galaxy S2” in this post.

We have already addressed hundreds of problems Galaxy S2 owners reported. Therefore, if you have concerns with your phone and you’re not under Sprint’s network, try to check the index page. If you can’t find your problem anywhere, feel free to email us at [email protected]. I am one of the people who’ll read your messages and I beg you, please provide as much details as possible.

We are serious in providing support to our readers that’s why we also use our Facebook page as another medium to answer questions. Or, you may join the Google+ community [click here] I created to extend our free support service. I usually have that page opened on my laptop so there’s a big chance you can catch me when you post your problems there.

Laptop Cannot Recognize Sprint Galaxy S2

Problem 1: Hi Droid guys. First of all, I would like to thank you for your effort in providing free support for us Android users. You’re doing us a really big favor. By the way, I own a Galaxy S2 Epic 4G Touch from Sprint. After more than a couple of years, the phone is still working perfectly fine. My problem is not about the phone per se, rather about my laptop that refuses to recognize my phone. Consequently, I cannot transfer my photos like I used to.

This problem started about a week ago when I noticed my desktop has changed and I lost some of my files. My laptop, one day, refused to start up so I had to bring it to a tech and have it fixed. But when I got it back, the desktop was changed and it had the default wallpaper. What could be the problem why it cannot recognize my phone? Regards, Annie.

Related Problem: Hi guys, I have a Galaxy S2 that when connected to the computer does nothing. Before, there was a box that would pop up once the computer detects the phone, it doesn’t pop up now. Instead, there is a box that pops up in the lower-right area of the screen saying that the USB device that’s plugged in cannot be recognized. What seems to be the problem? I’m using my son’s laptop because my computer was damaged a couple of weeks ago. By the way, I’m using Sprints services, if that matters.

Solution: Hi Annie. As long as we receive emails from our readers seeking assistance with their Android problems, we will never stop publishing these support articles.

Now, about your problem, it’s apparently just a driver issue. You know, there are little programs or files that your computer needs to be able to recognize your phone when connected via the USB port. Don’t worry, it’s not a big problem. To fix it, please follow the steps below:

  1. Using your computer, log on to: http://www.samsung.com/us/kies/
  2. Find the blue button that says “KIES 2.6” and click on it.
  3. Depending on how fast your connection is, the download process may take a few minutes.
  4. Once download is finished, install the program on your computer.
  5. Once installation is complete, you can connect your phone to your computer.

That’s all you need to do to have everything working again. Alternatively, if you don’t want to install KIES on your computer, you can download USB drivers for your device from here. You will be download an executable file so you need to run it for the drivers to be installed.

Sprint Galaxy S2 Can’t Send / Receive MMS Messages

Problem 1: Hello, I’m with Sprint and use the 2-year old Galaxy S2 Epic 4G Touch phone. Everything works great except sending and receiving picture messages. I’m not quite sure when it started but I know I was able to send some pictures to my daughter last month. Yesterday, I tried sending one from my husband’s phone but I didn’t get it. I tried sending from mine to his, it didn’t go through. I’m just a user and I really don’t have any technical knowledge how to troubleshoot problems like this so I need your help so bad. Please include me in your next publication as I really need this problem fixed as soon as possible. — Monica

Related Problem: Hi Harold, I’ve been reading a lot of your posts and I enjoyed them. I’ve never really sent picture messages with my phone before so that feature was left unused since I got the Galaxy S2 in 2011 from a Sprint store. I always had Wi-Fi network at home or in the office but I wonder why I can’t send picture messages. Can you please guide me through solving this piece of a puzzle. Thanks! Please keep the good service. — Jewel

Solution: These are two very identical problems worded differently. Both phones were from Sprint so they were properly set to work in the network. I’m not sure if Sprint changed its APN and failed to send the updates to its subscribers but based on these descriptions, APN settings are the first things that should be checked.

To be sure that you got the correct APN, I suggest you call Sprint’s tech support hotline and ask for it. I am not sure if Sprint’s reps can send the APN to the subscriber’s phone wirelessly but it would always be wise to ask for a hard copy of the APN so that if the wireless transmission failed, you can edit the APN in your phone by yourself. To edit the APN, follow these steps:

  1. Open the Settings.
  2. Select Wireless & networks.
  3. Select Mobile Networks.
  4. Select Access Point Names.

Sprint Galaxy S2 Stuck On Samsung Logo

Problem: Hi Harold and Chad. I have been following all your support articles for the Samsung Galaxy S2 and I enjoy every bit of it. I have a little problem with my phone and it started just about a couple of days ago. I don’t want you to think I’m techie because I really am not and honestly, I don’t know what the problem really is. I mean I just woke up one day and found out the phone is off. So, I turned it on but couldn’t get past the logo. Please, if you know how to fix this, tell me. Thanks. — Mia

Related Problem: I really need your help guys because I need my phone for my job. I just experienced this problem and I don’t have a single clue how to fix this. Unlike before, my phone now doesn’t power up to the Home screen. The display stays black after the Samsung logo. I tried leaving it in that state for 3 hours but still the same. The phone is an S2 and I got it from Sprint last year. What do I need to do?

Solution: Being stuck on the logo could mean a lot of things but there is only very few things you can do to fix it. It could have been better if the owners indicated what caused the phone to act this way or what the performance of the phones were prior to this problem but they don’t. So, my suggestions will start from the very basic:

Soft reset – I always treat problems to be minor especially if they happened without apparent reason. If that is the case for these problems here, then soft reset can fix them. All you have to do is remove the battery, press and hold the power button for a minute, replace the battery and turn it back on. If that won’t work then there are two other procedures you can try.

Boot in safe mode – this will boot the phone normally minus all third-party or downloaded apps. Everything that runs are pre-installed apps and core services. If the phone can boot successfully in this state, then there is a big chance the problem can be fixed. Here’s how you boot in safe mode:

  1. Remove the battery from the phone.
  2. Re-insert the battery.
  3. Press and hold the Menu key.
  4. While holding the Menu key, turn on the device.
  5. When you see the lock screen, you can release the Menu key.
  6. ‘Safe mode’ displays in the lower-left corner.

Boot in recovery mode – it is very important that you could boot in recovery mode because this is your last shot to fix it. In recovery mode, you can wipe the cache partition or perform factory reset. Here’s how you do it:

  1. Turn off the device.
  2. Press and hold both Volume Up and Volume Down keys at the same time.
  3. Press the Power key only until the phone vibrates once, then release only the Power key.
  4. Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.

If you’re lucky to be able to reach this far, try wiping the cache partition first. If that wouldn’t work, then proceed with factory reset but please note all your data will be lost. In case this procedure fails, bring your phone to a tech and have it checked.

Sprint Galaxy S2 Won’t Take A Charge

Problem: Hello droid guys, I’m not into new gadgets or cellphones so I stuck with my Galaxy S2 for a long time already. I can’t complain about my phone’s performance for the past couple of years, however, this past couple of days, it seems that the phone is refusing to take a charge. I’m using the same charger, the original one, but the battery percentage doesn’t go up. For example, I plug the phone in and it’s currently showing it has 25% of battery, when I come back after an hour it still showing it’s 25%. What is the problem? Do you know a fix for this? Thanks. — Rommel

Related Problem: Hi, I have one problem with my Galaxy S2 (it’s Sprint’s), more often it doesn’t charge up but there are times when it does fine. Does it mean I need to upgrade to a newer phone or is there something I can do to fix it? Please advise.

Solution: The problem with this issue is that it covers a lot of possibilities; it’s possible it’s a charger problem, a battery issue or even a serious hardware glitch. I suggest you give this a time to troubleshoot what the cause of the problem is. You need to rule out possibilities that it’s a charger or battery problem. After all, these two components are expendables. Here’s a step-by-step procedure you can follow:

  1. Try to charge the phone normally. If it didn’t charge, try to wiggle the cable or secure the connection in the phone’s microUSB port.
  2. Connect the phone to a computer and see if it can detect the phone. Your device should also show the lightning bolt on the battery icon as an indication it is charging. If it’s not showing, there is a possibility that the cable is faulty or has a break somewhere. Try to use a different cable to see if it makes a difference, or try the cable with other devices.
  3. If you’ve verified that the cable is working fine and the phone still refuses to charge, the battery should be your next suspect. If you can borrow a spare battery from someone who also owns an S2, that would be very helpful. I don’t immediately recommend buying a new battery because there’s no guarantee it’s the problem. Or, you can also insert your battery to other phones to see if it works fine.
  4. After you’ve verified that the problem isn’t with the charger nor the USB cable and battery, then it’s a hardware issue. The most common suspect is the USB charge port; it is replaceable but if that is the case, it’s wise if you just bought a new phone or upgrade.

I hope this helps.

Sprint Galaxy S2 Has Become Very Slow

Problem: Hi guys. I hope you can help me with my problem because I’ve been suffering from it for almost a week already. I called Sprint tech support about it but all they insisted was to master reset the phone. I wouldn’t do that if there are other options because there are data in my phone that I don’t want to lose. That’s the reason why I contacted you guys hoping you have other ways to fix this problem. By the way, my phone is a Samsung Galaxy S2 and it I’ve accumulated a lot of apps already after more than a year of use. Please help me. Thanks. — Elizabeth

Related Problem: My Galaxy S2 is now running very, very slow and I think it was caused by some apps I recently downloaded but it could also be something else. The thing is I can’t do anything on my phone because if it doesn’t run so slow, it hangs and I have to remove the battery to remove it. I can’t even go to the settings to factory reset it. So, I really could use some of your tips and tricks on how to fix this problem guys. I happen to be a noob with technology that I only know how to use my phone and not fix issues with it. I though smartphones are problems-free but this issue I have is causing me a lot of trouble. Regards, Mike.

Solution: Performance issues are often caused by third-party apps that have gone rogue or crashed. However, they could also be caused by firmware glitches and issues with pre-installed apps and core services. So, it would be wise to isolate the problem first. To do that, follow these steps:

  1. Remove the battery from the phone.
  2. Re-insert the battery.
  3. Press and hold the Menu key.
  4. While holding the Menu key, turn on the device.
  5. When you see the lock screen, you can release the Menu key.
  6. ‘Safe mode’ displays in the lower-left corner.

When in safe mode, observe the performance of the phone and if it runs fast, the problem is with your third-party apps. You need to find the one or some that are causing the issue and uninstall it / them. Also, while in safe mode, backup all your data or you can connect your phone to a computer and copy every bit of information you don’t want to lose.

After a couple of years of continued use, the phone may have accumulated a lot of data and some of them are already corrupt. You need to clear those and one effective way to do that is factory reset. But I suggest you do the factory reset via recovery mode because the system wouldn’t just delete all data and caches but reformat both the cache and data partitions.

  1. Turn your phone off.
  2. With the phone off, press and hold the Volume Up key and the Home key, then press and hold the Power key. You’ll see the Android recovery screen.
  3. Scroll to Wipe Data/Factory Reset using the Volume Up or Down keys. Select with the power key.
  4. Scroll down to Yes, Delete User Data and select it.
  5. Back on the first screen, scroll down to Wipe Cache Partition and select it.
  6. Your factory reset is now complete.
  7. Go to Reboot System Now to restart the phone.

“Unfortunately, the process android.process.acore has stopped”

Error: My Samsung Galaxy S2 is giving me an error message “Unfortunately, the process android.process.acore has stopped” and it becomes really, really slow. It was never abused and I don’t have a lot of apps installed so I’m really surprised when I first got this problem. At first, it disappeared and I thought the problem was fixed right there and then but it came back and now almost every minute the dialog box appears and I can’t do a thing on my phone. What am I gonna do?

Solution: The most common cause of this error message is a third-party app that crashed and affected the normal operation of a pre-installed app or service. A reboot may be able to fix this problem, so try that one first. If that doesn’t fix the problem, then boot in safe mode and observe the phone to find out if it still gives the same error message. If the error message still shows up even in safe mode, then one of the pre-installed apps or core services may have crashed. Wiping the cache partition in recovery mode may fix it. Otherwise, you really need to perform factory reset.

However, in case the problem was fixed in safe mode, you just need to find the app that’s causing it and uninstall it. Then, you can boot to normal mode again and the phone should be working properly after that.

“Unfortunately, Messaging has stopped”

Error: Hi Harold, every time I try to text someone, I get the message saying “Unfortunately, Messaging has stopped.” My phone is the Epic 4G Touch from Sprint and it hasn’t been doing this before. It started about 4 days ago and I thought it was just a temporary issue but it didn’t go away. I called Sprint and they wanted be to reset my device, at least, that’s what they said but I don’t know how to do it. I hope you can help me with it. Thank you.

Solution: Factory reset can sure fix this error but the problem is you will lose all your data just because of this very minor problem. Here’s one solution that I’m sure could fix this problem but not all your data, just your text messages:

  1. From the Setting menu, touch Apps or Application Manager.
  2. Verify the All tab is selected.
  3. Find and touch the Messaging application.
  4. Touch Clear Cache and Clear Data.

I hope this helps.

Play Store App Gone From Sprint Galaxy S2

Question: Hi droid guy, I have a very strange problem–the Google Play Store app cannot be found anywhere in my phone. The thing is, I dropped this phone and broke the screen. So, I brought it to a technician to be fixed. It was fixed by he said he had to wipe all data after the installation of the new display because the phone will not boot up completely. The phone works fine but the very important app is lost. Have you heard of this problem before? My phone is an S2 and I’m on Sprint.

Answer: It seems like the technician may have flashed the original firmware, Android 2.3 Gingerbread. You cannot find the Play Store but you must have the Market app. When you open that app you will be prompted to update it. After the update, it will be replaced with the new icon of Play Store and correct name.
