#1. Galaxy S2 Wi-Fi won’t connect

Q: Hello. I saw your article on the Samsung Galaxy S2, and I was wondering if you could help me with an issue . Anytime I turn on my wifi it doesn’t fully boot up. The icon gets half lit in the drop down status bar, and the settings wifi area just says its starting up. I have found a sort of solution. I rotate my phone sideways and bend it, as if to snap it in half, I know it sounds weird. But it usually connects. Sometimes if I let the pressure go, it goes back to searching again. I suspect the WiFi antenna is loose. If so how do I replace it? Your thoughts are greatly appreciated! — Jon

A: Exactly what I’m thinking. The antenna board is located at the bottom of the phone but there is a cable that runs from the bottom to the area just above the battery. Both ends are detachable, so if one end is not properly connected, the result could be the same as the one you’re experiencing now. That explains why it could connect better if you applied pressure. There is a possibility that it is simply a loose connection. So, if you’re confident enough, open your phone up and secure the connection of the antenna on both ends.

#2. Galaxy S2 refuses to boot up

Q: Hello, my friend’s phone was fully charged this morning when we went to work he turned it off for our morning meeting then when we left he went to turn it back on and it had short vibrations and only showed the Samsung name on the screen and that’s it. We’re not sure what’s wrong with it? Please help. We work in camp and aren’t able to go anywhere for another week. Thanks — Kyla

A: That’s weird. Since we don’t totally know what happened, let’s stay on the safer side of things. I want you to try to boot the phone to recovery mode and wipe cache partition if booting up is successful, follow these:

  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.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Home (GB only) or Power (ICS only) key to select.
  7. Make sure Reboot System Now is highlighted and press the Home or Power key to reboot.

#3. Galaxy S2 asking for SKT USIM

Q: Dear Sir, I am a user of Samsung Galaxy S2 smartphone, when i am trying to update it, it says, Failed to software update. Use SKT USIM to progress update. I am a new user and don’t know what is SKT USIM. Kindly help me and guide through easy steps to solve my problem. Details of my smartphone: Name: Samsung Galaxy S2, Model: SHW-M250S, Android 4.0.4 from Korea. I will be thankful to update my cell phone. Thank you and best regards.

A: The phone is asking for a Korean USIM and I’m sure you don’t have that SIM already and even if you do, you cannot get service using it. So I suggest you update via Wi-Fi… remove the SIM that’s currently mounted on your phone and try to pull down the update. If that doesn’t work, use KIES to do the update for you. And if that doesn’t help either, well, backup your data and perform factory reset, I’m sure that would work.

#4. Galaxy S2 can’t detect SIM when charged

Q: I have a galaxy S2 which doesn’t charge at one go…but after numerous attempts of plugging the charger to the phone it starts charging…but as soon as it starts charging, the SIM goes off and a No SIM error starts flashing with a no entry symbol in the place of network strength. Though it acts normally when switched off. when i connect the charger in the switched off condition, it instantly starts charging.

TRIED:

  1. Factory reset
  2. Tried with several chargers
  3. Changed Battery

A: I encountered a similar problem before, though the phone wasn’t a Galaxy S2. The problem was, whenever it was plugged in to charge, the SD card unmounts and the screen flickers continuously. I found out, one of the pins in the microUSB port on the phone was slightly bent that every time the cable was plugged in, the pin touches the other pin causing inconsistencies on the circuitry or flow of electricity inside the phone. Apparently, the fix was to straighten the bent pin.

My suggestion for you is to first check the port on your phone if there are some discrepancies. If not, please bring the phone to a technician for further checking. Remember, once circuitry is messed up, it’s just a matter of time before the phone or its components inside get fried. So visit a shop as soon as possible.

#5. Galaxy S2 won’t go past carrier logo

Q: Hi there I have a Samsung s2 thru AT&T and it randomly shut off then starts vibrating. I read on your forum about possible power button sticking so I did that and now its turning on and charging which it didn’t before but now it won’t go past the AT&T start up. Just wondering if it could be the battery or what? — Lauren

A: It could just be some corrupt caches that hinders the normal boot up. Boot the phone to recovery mode and wipe the cache partition so the phone will be forced to cache newer ones. Follow these steps, please:

  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.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Home (GB only) or Power (ICS only) key to select.
  7. Make sure Reboot System Now is highlighted and press the Home or Power key to reboot.

#6. Galaxy S2 charges very slow

Q: Hello, I have tried taking the battery out, turning on then battery back in etc the phone will not stay charged? Last night it was plugged into the wall charger for at least 7 hrs and it was only at 24% then it will start beeping saying it charging when doing nothing? I am not sure what the issue is.

A: I just want to rule out the possibility that processes and apps are eating up the battery more than the charger could provide. So, try to boot the phone to Safe Mode and enable Flight Mode. Here’s how you boot to 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.

If the phone charges normally when in Safe Mode, you need to do factory reset because it’s a hassle to go through each of your apps and disable them to know if they eat up your battery or not. However, if the phone still charges very slow even in Safe Mode and Flight Mode enabled, it’s a problem with the USB port or the battery. Both can be determined when you have the phone checked by a technician.

#7. Galaxy S2 video player stopped working

Q: Sir, last morning I was update my Galaxy S2 to 4.2.2 version and all the things perfect but when I open the mobile video player its shows “unfortunately video stopped working” other apps and videos are working perfectly. Please tell me the issue?

A: It could be that the update messed up the cache or data of the video player. The immediate solution to this is to clear both from the application manager so the phone would be forced to cached newer ones. Here’s how:

  1. From any Home screen, tap the Menu key.
  2. Choose Settings.
  3. Tap the Applications manager.
  4. Scroll to and tap your video player.
  5. Touch Clear Cache.
  6. Touch Clear Data (please note you may lose your settings when you do this).
  7. Tap OK.

If this doesn’t work, however, try wiping the cache partition:

  1. urn 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.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Home (GB only) or Power (ICS only) key to select.
  7. Make sure Reboot System Now is highlighted and press the Home or Power key to reboot.

#8. Galaxy S2 can’t recognize SIM card

Q: Love the site hope you can help me. Samsung galaxy s2 working okay with O2 SIM card but now displaying message no network registered. Now have new SIM card from o2 but still not working although other SIM cards do work in the phone. Any ideas? Phone no longer under guarantee and I am technophobic any assistance gratefully received. — Kenny

A: I am certain that in the U.S. a SIM card is tied to one serial number only, although the phone number is transferrable. But I am not sure if it’s the same in the area you’re in. I’m afraid it’s not something we can help you with because basically the problem isn’t with the phone as you said it works well with the original SIM card. So I suggest you call O2 and ask if you can just insert a different SIM card on your phone and use it.

#9. Galaxy S2 can’t send MMS

Q: Hello, I have 2 problems with my S2. I am not very tech savvy so please forgive me. 1st- cannot send or receive pictures or videos by text messaging. Called service provider and they said everything on their end is good and it should work. It is not, any suggestions to fix? 2nd- some of my pictures are disappearing from my gallery that I haven’t deleted. Any idea on how to find them? Thank you!

A: Of course, the rep would tell you your account is in good standing because in the first place, it doesn’t show on their end what the problem really is. As long as you have an account with them and that you’re enrolled in a plan and you have data or airtime left, everything would look good on their end. But did the rep checked your APN settings? Call your service provider again but this time instead of telling them what the problem is, ask for correct APN Settings and have the rep walk you through setting it up on your phone.

As to your second issue, I think you’re talking about synced pictures. You need to have a consistent internet connection to view them. If there’s no internet connection, you cannot open them, although there would still be thumbnails left in your Gallery.

#10. Galaxy S2 can’t connect to Wi-Fi

Q: A few months ago my S2 stopped connecting to my house Wi-Fi. I tried doing the hard reset (took the battery out). I read online that this seems to be a major problem with this model. Please help, without the Wi-Fi my phone is killing my Data package. Thank you!

A: If the phone cannot connect to your home Wi-Fi but can connect to other networks, then the problem is not with the device but with your network. But if it can’t connect to all Wi-Fi networks, I suggest you backup your data and perform factory reset as there could be some problem with the firmware or some conflicts perhaps:

  1. Press and hold both Volume Up and Volume Down keys at the same time.
  2. Press the Power key only until the phone vibrates once, then release only the Power key.
  3. Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  4. Press the Volume Down key to highlight wipe data / factory reset.
  5. Press the Power key to select.
  6. Press the Volume Down key to highlight Yes – Delete all user data.
  7. Press the Power key to select.
  8. Press the Power key to reboot.
