Samsung Galaxy S4 Problems

The Samsung Galaxy S4 may be a good phone, but it also has its problems. Some Galaxy S4 users have reported some major problems with their phones. Some of them are software problems and some of them are hardware defects. Here are some of the problems that the users are reporting:

There have been reports that some Galaxy S4’s were getting very hot 46°C (115°F) not only when playing games, but even when the phone was idle (screen off)

The possible reason could be MediaServer. Check if ‘Mediaserver’ is taking up your CPU/Battery (Settings -> More -> Battery). If it is, disable it.

Screen Smearing Issue


Some other users are reporting that their screen is smearing, basically while scrolling dark greys on blacks smudge/smear purple.

A test for this is in settings, on anything grey if you slowly scroll up and down the grey bits go purple.

Battery Drain When Rebooting

When you turn the phone of and then on again, the battery levels jump down to 10-15 percent less of what it was before. It is also displayed in the settings battery status graph.
(This seems to be a problem with Android)

Vibration Of The Earpiece

When the volume is set to max during a call through earpiece, the slight vibration made because of the sound emission is felt on the back of the device (in a cheap way) and apparently, every s4 has this issue.


According to some users, there is lag when opening the Camera and Gallery App, Shutter lag when taking photos, and dialer and contact app taking longer than necessary to open

Launcher redraw

After opening an app for a few moments, like browsing the web or watching YouTube and then going to the launcher, the launcher will redraw, which means every widget and icon will disapear and after a couple of seconds will appear again.

Videos playing only sound

Occasionally videos, on any type of app will give only audio. Rebooting the device fixes the problem.

That’s all the major problems for now. Do you have any other problems? Post them down below and let me know.


  1. I have 2 isssue
    1.the camera many time take like 8-9,sec
    2.not able to change the fonts in the settings saying font noinstalled

  2. Problems with my first S4. Returned and swapped for another.
    #1 Would not connect to bluetooth.
    # 2 Major lag in texting as well as putting down symbols I.e. @ instead of the letter a without hitting the shift button..very annoying.
    # 3 Gestures are a joke..The dint work,period.
    # 4 Overheated and rebooted several times.
    # Dropped calls. No its not my carrier. Never happened once with my Galaxy Nexus.
    Ok now problems with my second S4.
    Everything above except that ones bluetooth worked fine.
    Either way took that one back as well.
    Wasted quite a bit of time with tech support..Good luck finding someone at Samsung tech support who can help you..Oh yeah forgot one more thing. screen mirroring wirelessly with a Samsung Smart T.V. works only if you don’t hold the phone more than two feet away from it.

  3. Bought an S4 from Verizon yesterday, phone will not allow me to access home wi-fi, after enter password Cancel button is accessible but connect button is gray and not usable.

  4. im having problems with the phone rings the screen is still black, or sometimes when I want to end the call, have to press the home button to get the screen back on. It’s extremely frustrating. When I reboot the phone its fixed, I think its a software problem. This is my first and last android device, if they don’t fix this problem soon

  5. My sound has suddenly stopped. I have tried the volume settings and restarting the phone but nothing is working.??

      • I’m experiencing a similar problem too. I have no sound/music at all until I use my headphones… annoyed as phone is only 6 days old and treated like a Baby!

        • Same problem here, sound reappeared for a few days, however it went out again, just works with headphones.

        • pfft…6 days?! i’ve had mine less than 24 hours and already with this and keyboard/display freezing issues. so not cool.

    • when i make a call, i cant hear any sound fr the other end but they can hear me. If i put it on speakers or bluetooth headset, it’ll work. It happen a wk ago, after I’ve used the s4 for 2 mths. Is this samsung quality?

  6. I always keep my cell phone on vibrate to prevent distracting others and carry it on a belt holder. I recently purchased a Samsung S4 and the vibration is not strong enough to feel the vibration. This was not a problem with prior phones including blackberries. How do I adjust the vibration strength?

    • Hi James
      1.Go to Settings
      2.Go to My Device tab
      3.Tap on Sound and open “Vibration intensity”
      4.Choose the vibration intensity for Incoming Call, Notification, and Haptic Feedback.
      That will fix your problem

  7. I have very little service. I had the earlier version of the Galaxy and had great service. Now I have very spotty service when all my other Verizon users are full bars.

    • im experiencing the same problems. Since im travelling a lot i choose the automatic connection to available service provider and now when im home i keep losing signal!

  8. Has anyone had this problem? I just bought a galaxy s4 to replace my iPhone. After importing all my contacts, I can only call or text people with a phone number format within Korea e.g. 010 xxxx xxxx. Calling or texting any numbers with the international format doesn’t work e.g. +8210 xxxx xxxx. Strangely, you can’t even enter a “+” with the s4.

    I went back to the shop but they were no help suggesting I just use skype to call or text internationally??!?

    The only success I did have was entering 001 before the number e.g. 00164… to New Zealand. People could receive my calls and texts however I couldn’t receive their replies to my texts. This also results in random phone numbers coming up so both parties don’t know who is calling/texting.

    Ideally, I want all my contacts saved in the international format so nothing changes when I go on holiday or leave Korea.

    Any help appreciated. It’s driving me crazy.

  9. 1st S4 bought through Verizon had major lag in all areas and difficulty swiping screen to unlock. 2nd phone stopped charging after 1 weeks use (other reports of this on Android Forum). Waiting for the 3rd S4 to arrive but Samsungs “Next big thing” is looking like a big flop.

  10. Can anyone help? Have had the galaxy s4 for about 5hrs. Working fine at first but now every time I open an app ect its doing a launcher redraw. Really frustrating me as would expect this from a brand new phone.

  11. My Samsung S4 volume is not working. I have it turned upon everything and no sound is coming out. The vibration works but that is all. Comments?

  12. My entire screen is glitchy colorful snow, sort of reminiscent of a completely broken board on a monitor. Minus the display, the phone “works” fine, even the touch.

    Here is the crazy part…the display is fine if I can navigate (by memory) to any screen with the keyboard pulled out, like replying to a text or typing in a URL. Then the screen is crystal clear.

    • Hi Laura.
      Go to Settings>My Device Tab>Display and untick “Auto Adjust Screen Tone” option. This should fix the flickering problem a little bit.

  13. Has anyone had any joy with the factory reset? my friends phone has just done the same. Tango and other calling apps work but not the phones own calling. Tried calling me a few time but getting no sound on my end or theirs, it was working a few hours before then just stopped.

  14. I bought a Samsung Galaxy S4 (GT-I9500) paying a whooping amount of INR 41,500/- on 08th July 2013. Within a week I suffered Mobile Network Signal Drop (NO SERVICE – ERROR SEARCHING NETWORKS) & Call Drops!!. I tried replacing my SIM card and trying other network provider’s SIM too. But the problem persisted. I also researched the internet and came to know that many of the users have the same problem! It’s definitely a handset fault. I contacted Samsung Customer Care on 16th July 2013 and they said that as a policy they could not replace my Samsung Galaxy S4 GT-I9500 as it has crossed 7 days period after purchase (NOT TO MENTION…RIDICULOUSLY SAMSUNG INCLUDES SUNDAYS TOO, EVEN WHEN THE CUSTOMER CARE CENTERS ARE CLOSED!!) Failing to solve the issue even after updating my software, now they have provided me with the option of replacing the motherboard of Samsung Galaxy S4 (GT-I9500). My charm of buying such an high-end phone has been completely lost and left me shattered fearing any more loss after motherboard replacement! I feel cheated buying a Toy of INR 41,500/-, when Samsung cannot even provide a stable BASIC necessity. It’s even more sad for me since I have still not started paying my monthly installments! ( At great loss here buying this phone. I DO NOT recommend Samsung Galaxy S4 to anyone, unless you want to waste your hard earned money.

    Can anyone provide me with a solution to this?

  15. Managed to fix it, my friend had Tango installed a free video call app same as vibr i think. well I rang the local 3 store up said about my problem, he couldnt think what the problem was then remembered that they had a customer in with a similar problem. What had happend was vibr had taken over the phones calling, so the phone would connect on a normal call but no sound. They uninstalled vibr and hey presto the phone worked… Pretty much the same for my friend their tango crashed a few times then the phone had its problem, so we uninstalled tango and the phone started to work correctly again.
    Long winded but I hope this helps.

  16. Constantly drops signal. Bars drive down to no bars to the crossed out circle. Phones around me, including a Galaxy S3 with the same provider and data plan have perfect bars while the s4has no signal. Missed calls, cannot surf the Web, cannot send or receive messages.

    Its the international version so in pay full price. Its a waste of phone and hard earned money.
    Constantly searching the forums and cannot find anything.
    I live outside the USA so I’m hoping I can get a replacement.

    I regret purchasing the s4. My partners s3 works like a dream.

  17. My Galaxy S4 screen has suddenly gone complete black, no image and no lighting. The menu button and the ‘back’ key towards the bottom of the device seem to be working though.

    I know the device is still working because I could receive calls on it – but only when I’m driving and my device bluetooth is connected to my car – because I’m unable to swipe on the right spot to pick up my call. It also vibrates when a call comes in, and it gives notification when new messages/emails arrive. I can even connect it to my computer and I even try to have it backed up etc. while the screen is complete black and non-functional.

    So the jist is, I believe the screen is shot – it is literally useless to me right now.

    I’ve tried taking out the battery, the SIM card, the memory card and then putting everything back in. I called my carrier’s technical support already and was told to back up the stuff on my device to Kies on my computer, which I did, and then he told me that I’d have to bring the device to a store to have it sorted out there.

    Any ideas?

  18. I am having trouble with my s4 every time I lock my screen the phone vibrates is this a setting? If so how can I remove it?

  19. I can’t watch youtube videos… if I use the Youtube app, it says unsupported video format and to create an account at but logging in to youtube thru a browser never helped… if i try to watch a youtube video through the browser (internet or chrome), the audio plays but the video never moves. Had similar problems with Galaxy Tab 2.

  20. I can turn all my volumes to whatever I wish except the media volume. its stuck at vibrate for some reason and it won’t let me move the bar. resetting the phone does nit work…. im thinkin I should just go get an iphone or somethin

  21. Taking mine back tomorrow due to issues dating back to Jan relating to the bluetooth issues identified in jellybean 4.2…my phone is jb 4.2.2 and they wont give me the v4.3 patch. Phone has video / audio sync issuess when streaming bluetooth on headphones wireless speakers…bluetooth is choppy and unreliabe.

  29. Hi, eversince I dropped my phone, I have been having software issues. It starts “dancing” around my screen ie: as I type my messages, it clicks on random messages to save, it clicks on wrong apps when I am trying to open another app, the screen dances etc. I did a master reset as well and taking out my batt and putting it back. It is still the same. I do not want to master reset again as it is troublesome to regain back all my apps and whatever not.

    Is there any thing I could do to solve this problem?

    please help

  31. hey all i have a problem in my galaxy s4 when it is in my pocket it become silent or if it is silent it become sound how to solve it? thanks for helping.

    • Diary, maybe the volume buttons are pressed accidentally when your phone is in your pocket? So your phone becomes silent when it has sound and vice versa.

  32. Hi im having a problem with my samsung galaxy s4 it dosent vibrate anymore and I have done everything to fix it and it still dosent work. Could a app I installed be stopping my phone from vibrating or do I need to get my phone fixed? PLEASE HELP ME 🙁

  33. I have a Samsung Galaxy s4…loved it in the beginning then a system update changed my love to frustration…along came the second update…nothing different just a few more non-deletable apps I have no use for…and some of the apps I found useful, now less so…the original driving mode (now apparently called Hands Free)…seems as if it was reduced to a lesser, generic version of what was once one of my favorite features. Replacing the pleasant, actual human like voice is now a monotone digital drone of a voice that aside from its apparent annoyance…can’t understand a flipp’n enunciated word I say…What was a feature that attracted me to buying this phone is now a useless waste of precious space to me..let me say reading all your posts have been educational. I don’t know a lot..but can find my way around a device as to basic function..perhaps a few extras…know nothing about rooting. I am frequently kicked off my own wifi at home, which seem to improve after the last update but alas…not permanent. I am reading as some asked model numbers and those that replied mentioned GTxxxxx….mine starts with SCH…after update 2 mine says kernel version and other are talking jelly bean. I am lost. Videos were once flawlessly played…now freeze or stop constantly to buffer…I deactivated the damn eyeball thing thinking it was that sensitive…not the problem…I could go on…but babbled enough already. Currently I am super annoyed having paid for and received an already working phone…which after “up” grading, actually “down” graded some of its original amenities…to what I feel are lesser versions of what was. In closing, being a Verizon customer and of course no longer having unlimited data available, it burns me up when I look on my icons and see I’m not even connected to wifi…but it keeps telling me it’s scanning…then available…click to connect nothing…OR connect only to be disconnected. Same router with no problems originally….sorry so long…*sigh*

    • Hi M. Hoffman, is your warranty still available? If not, then you might consider flashing a firmware which will revert your phone to the Android version it had before the update. Hopefully you will not have any problems anymore.

      • Thanks for responding…can you explain more about your suggestion for firmware?…where and how to install…not sure about warranty…I probably have the phone for 6 to 8 months

  34. I recorded a few videos on my phone and they all played fine but now one will play without sound where the rest are ok can you help plse

      • Generally i use mx player or the video player which is there on S4. If the flickering starts once it keeps on flickering for other videos too and on both the applications which used to run normally on my phone before the problem occurs, and i have to go for a soft reset to solve it.

  39. Whenever I receive a text with a photo from an iPhone user I get a message that one or more of the components have been deleted. Either the message was to large or unsuitable for my handset. But I can get pictures from anyone else.. His can I fix this?

  40. Whenever I try to install retrica app on my Galaxy S4 it installs perfectly, but when I open it an error appears and the app closes.
