Problem #1: Galaxy S4 “A USB device has exceeded the power limits of its hub port” error

Yesterday I noticed that my car charger was not charging my phone. Tried to charge it using different wall units – no luck. It only says “Please connect your charger” without realizing it has one plugged in. Basically what happened is: the phone died, I got replacement battery that still had little charge, it is not working either.

I tried USB cable and laptop – started to get message “A USB device has exceeded the power limits of its hub port”. I tried to reset it — no luck. Once when connected to the laptop, the phone got hot. That does not happen again, I keep trying different chargers. Please, help.

I blew the air into the charge port to get rid of any debris or dust. The port visually looks not damaged. Any suggestion? Please, I don’t want to get that phone replaced yet.

Thanks! — Inga

Solution: Hi Inga. There must another failing power component that’s failing. Power issues can be caused by other factors which are not limited to the battery or USB charging port. An S4’s power management scheme is handled by other components and one of them must have stopped working. That a replacement battery did nothing to change the situation is a clear sign of that. Difficult it may be, we believe that the only remaining option for you right now is to seek a way to have the phone replaced, or at least checked and repaired.

Problem #2: Galaxy S4 voice option when texting not working properly

Hello. I have a Samsung Galaxy S4 running Android 5.0.1.  I tend to use the voice option when texting and am having difficulty finding out what happened to the edit function.

Until recently, I would touch a word and a list of alternatives would pop up.  For instance, if the word was “mat” a list of: Matt, map, at, and so on, would pop up upon touching the word. I could then select the correct word and keep talking without missing a beat. This function all but disappeared about two weeks ago. Now, touching the word does nothing and holding the word only allows for copy, paste, etcetera.

I cannot find anything online that addresses this issue.  I’m starting to think my wife is correct and I have truly lost my mind.  I have never had a smart phone or used text before I got this phone so I know there was once a way to perform this edit.

Please help!

Thank you in advance!!! — RC

Solution: Hi RC. A bad update may be behind the problem. What you can do to try is to wipe the cache partition first to see if that will make a difference. Here’s how it’s done:

  • Turn off the Galaxy S4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the S4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Should refreshing the system cache won’t help, make sure that you also delete the messaging app’s cache and data. For example, if you are using the stock Messages app when texting, you have to go into its App Info page to do the job. Simply follow these steps:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Choose the name of the app that has been going rogue.
  • From there, you will see the Clear Cache and Clear Data buttons.

Tapping the Clear Data button is the virtual equivalent of app re-installation and will result in the deletion of your text messages. Make sure to back up important conversation threads before doing it.

Problem #3: Galaxy S4 “AP currently not in use. Internet connection slow” error

Dear Sir, Greetings!

Whenever I am connecting to my Home wireless router (Asus RTN66U) from my Samsung Galaxy S4, I obtain the following message under Smartphone Network switch Window “AP currently not in use. Internet connection slow,” sometimes pop-up message “Failed to obtain IP address” and sometimes WI-FI Network status showing “Saves”. My same S4 connecting normally to other Wi-FI routers without any issue and also my other smartphone  connecting smoothly to the same home router without any issues. I have rested my router but nothing get corrected same error messages. I have tried many checks in my S4 also, but all in vain.

Note: Please see the attached  “error screen” which displayed in my S4. Thanks. — NASRELDIN

Solution: Hi Nasreldin. The error “AP currently not in use. Internet connection slow” can sometimes pop up if your phone’s Wi-Fi configuration is set to avoid perceived slow networks. To fix this, simply do the following:

  • Go to Settings
  • Tap Wi-Fi
  • Click on more settings (three-dot icon)
  • Tap Advanced.
  • Uncheck Avoid poor connections option.

If the issue remains though, try modifying Wi-Fi settings by using a static IP instead of DHCP. Here’s how:

  • Go to Settings
  • Tap Wi-fi.
  • Select your Wi-Fi network, then tap Forget.
  • Select your Wi-Fi network again. Click the 2 check boxes, put in your password and scroll down to where the option is either DHCP or Static.
  • Select Static and enter your computer’s IP address. If you don’t know how to check your computer’s IP address, simply use Google for instructions.
  • Tap OK.
  • Your phone should be able to connect to your network without problems now.

Problem #4: Galaxy S4 won’t turn on

So i have has my Galaxy S4 for awhile but never came by a problem i could never fix or find solution. But this time i’m not so lucky. So i was on my Galaxy S4, went to charge it when battery was low but not dead. when i went to go check on it, it was just a black screen. A few times when i took the battery came out, it vibrate, Samsung Galaxy S4 words come up then cut to black screen.

I’ve tried to do a factory reset by (holding power button + volume up and down + home) but didn’t work. It didn’t even go to option screen where got make your choices in small blue text. I tried taking out the battery, nothing. i tried holding the power off with no battery in it for a minute, wait 10 min then put the battery back in and only response i got were same results as before ( vibrate, Samsung Galaxy S4 words come up then cut back to black screen). i have no idea what to do at this point. i really don’t want buy new phone but i don’t want spend a ton to get fixes ether. i hope you guys can help. thanks again. — Alex

Solution: Hi Alex. Usually, there’s little to nothing that an average user can do to fix an Android phone not booting up normally. The most likely reason for the problem is hardware failure. It can be anything at this point although one of the most common hardware failures that we know is a bad power button. We don’t do hardware troubleshooting though. If you’re looking forward to getting advice or tips how to diagnose and fix a hardware issue, please use Google to search for instructions. We highly recommend that you let a professional check the hardware status of your phone though. Either you try to fix the issue yourself or let a technician handle it for you. Either way, you still end up investing something to have your phone fixed.

Problem #5: Verizon Galaxy S4 can’t send text message

Hi. I have a Verizon Samsung S4 (since fall 2014) but have been using a German SIM card while living in Germany. I have never been able to send text messages here (worked fine with the Verizon SIM card in the US), but have always been able to receive them. I have no issues making or receiving calls. Internet (wifi and mobile) work just fine. I used this same German SIM card on an iPhone with no problems whatsoever. I read online that it may be a problem with where my messages are being routed through (i.e. Message Center). Verizon has absolutely no clue when speaking to an “expert” in the “technical department.” I am unable to find the Message Center on my phone (option is not available in the Settings Menu for the Messaging application. I tried rooting with “Kingo ROOT” and accessing behind the scenes with “Advanced Signal Status” and found the input box for “SMSC:” but every time I close the program, the number I input (for my current network/cellular provider) disappears and I still cannot text.

Please help! — Amy

Solution: Hi Amy. Verizon is notorious for locking things down even though the device has already been carrier unlocked. Your problem is in fact common and can only be remedied by changing the network type you’re on. The exact network type depends on the area where’re you’re at. Some users have reported that they can send text message if they switch to 2G or 3G but not when LTE is selected.

Problem #6: Rooted Galaxy S4 dialer app not working

I have sprint Galaxy S4 that was flashed to Boost Mobile. After having the phone flashed i decided to root it. I used King Root 4.4.8 and it rooted without a problem. I started deleting system apps i wouldn’t use which was fine up until i got to the dialer stock app. I just didn’t like it, so i used ROM Toolbox Pro to go to the system phone dialer app, and it had an option to convert system to user app. I already had a third party dialer app installed that i liked. So i hit the button to convert the system app to user app and i wait for it to do its thing and it shows option to now convert user app to system. So then i figure i should be able to convert the third party app to a system app and it gives the option. So i do it thinking that, if i now have a better dialer app that i can now uninstall the one system app that i just converted to a user app. This was not the case.

As i go to use my converted third party app it didn’t dial out. It was as if i didn’t have service. So I go to use the original dialer app, and when i hit the call button i get a message that said “Unfortunately contacts has stopped”.

So the phone wasn’t getting any service and my signal indicator had an X over it. I thought what can be done can be undone. I went back into Rom Toolbox Pro to look for the system app that i converted to a user app, and i couldn’t find it. In its place i found two separate files one was phone utilities, and the other just said phone. No green phone icon like it originally had. The icon for phone was the one i chose first to convert back, but when i go to the advanced option to hit covert to system app it somehow deleted the app or file. It didnt show in the apps list at all. I didnt even bother with the other phone utilities for fear it would do the same.

I’ve tried all the little phone codes from the dialer app, the third party one, but i still get the same error message. I ended up taking the phone to a Samsung retailer to be flashed back to factory settings and the retailer brought up a screen that showed my phones system said custom even though the root app had been uninstalled. His galaxy phones system showed official. The Wi-Fi still works. If i go to Settings, mobile network it says unfortunately com.android.phone has stopped. I don’t wanna give my phone up. What can be done. — Michael

Solution: Hi Michael. It looks like you only have one solution left to do — flash the original firmware. We are not sure if what you mean by Samsung

Retailer flashing back to factory settings is factory reset procedure or flashing the stock firmware. If it’s the former, make sure that you flash the stock, original firmware to your phone to bring back the default settings. If this won’t work either, then that means that either the current firmware has already been saved permanently on the phone’s memory, or the firmware modifications have messed up the system. Either case, it means that you simply can’t use the phone normally like before.
