S4 Video Streaming Issue

Problem: hi I have a s4. I have had the phone nearly 2 years a.d only recently when watching videos on Facebook, youtube, or any other site. after around 30 seconds the video stops playing but the sound continues? any help would be much appreciated. also when I phone or someone phones me the other person hears a echo of my voice? thanks

Solution: It looks like your phone is experiencing a lag issue when streaming videos. You should first check if this issue occurs when connected to a specific Wi-Fi connection or if it occurs when your phone is connected to any Wi-Fi connection. This allows you to eliminate any connection related issues.

If the connection does not have a problem then the issue may be caused by a corrupt temporary data. Just wipe the cache partition of your phone then check if the issue still occurs.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key
  • When the phone vibrates, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select. The phone will automatically restart after the cache is wiped.

S4 Wi-Fi & Text Message Lag After Lollipop Update

Problem: Hi, I currently own Galaxy S4 and after updating to Android Lollipop, I am presented with a myriad of problems. I have tried everything online but to no success. I will try to explain my problems in detail.

  1. Wi-Fi – When trying to connect to Wi-Fi, it takes forever to turn on. Whether I do it from dragging down the bar from the top or from settings, it takes at least over 60 seconds to just turn on. The icon stays slightly dimmed and doesn’t full turn bright to signify it’s on. I have the Smart Network Switch off and it still has the same problem. Also, after it has turned on, it doesn’t connect to the networks I have saved. Clicking on a network, I have saved, it pops up asking me to type in the password again like it’s a new network. I restart my phone and it connects without a problem. It does this every time I turn Wi-Fi off and on again.
  2. Text Message – I cannot send text messages. When I send a message, the circling icon keeps circling and after a long time, also usually after 60 seconds, it finally sends. Thank you.

Solution: It looks like data from the old software version is having a conflict with the Lollipop update which in turn causes these issues to occur. The quickest way to resolve this issue is to perform a factory reset on your phone. Just make sure to back up your data before proceeding.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

S4 Can’t Send Or Receive Large Data Using VPN App

Problem: Hi My name is . I’ve been using Samsung S4 for 2 years now is quite cool. But something pop recently of which I don’t understand.  That’s I’ve started using vpn app on my phone recently,  but it can’t receive bigger data sent or received.  However,  my other colleges are using the same app but is working perfectly on their android.  Secondly I switched my sim into their phone to resolve and identify the problem. What I’ve seen was it working perfectly in theirs. Receiving big data or sent.  Whiles their sim card in my phone still behave the same . Kindly assist me to resolve this issue please.

Solution: You didn’t mention what VPN app you are using. Anyway, it’s most likely an app setting issue. Try to check on the VPN app settings by comparing it to the settings used by your colleagues. Make the necessary changes on your app if there are any differences.

S4 Mobile Data Not Working

Problem: Hello, I googled the problem going on with my phone and came across your web site, was wondering if you could help.  I put in my Sim card this morning and all my text and calls were working but my mobile data will not and I’ve turned the device its self off and on  my mobile data yet it still will not work. I ordered the phone from eBay but it a new phone, I’m using the same Sim as i used before and I’m with the same provider.  If I put the sim back in my old phone, the Nokia lumia 1320, it all works again. So I can do everything BUT use my data.

Solution: This issue is most likely caused by a wrong APN setting on the S4. Open your phone APN settings by going to

  • Tap on Apps
  • Tap on Settings and then tap on More networks
  • Tap on Mobile networks
  • Tap on Access Point Names

Check if your phone has an entry for APN. Compare your APN settings to the settings your carrier is using. You can check on the settings on your carrier’s website or better yet you can contact the technical support team of your carrier and have them assist you in getting the correct settings.
