AT&T Galaxy S5 Lollipop Problems After Android 5 Lollipop Update & How To Fix Them

Samsung-Galaxy-S5-Problems-28

AT&T recently rolled out Android 5 Lollipop update for Samsung Galaxy S5 and while many have been excited about it, there were owners who were also disappointed due various problems they’ve encountered immediately after the installation. It wasn’t a surprise though, because S5 owners from different carriers already complained about the problems brought by the recent update. True enough, many of those reported issues plagued AT&T S5 owners. The following are just some of the emails we received from our readers.

While I specifically cited that these problems occurred in AT&T-branded S5, the troubleshooting procedures and solutions will work with S5 variants as long as the problem isn’t carrier-specific.

AT&T Galaxy S5 Lollipop Update Didn’t Install

Problem: Hello guys! I have a problem with my phone but before anything else, it’s a Galaxy S5 that I got from AT&T, my service provider. I did receive the notification for the update and the download was smooth and all but when the time came for the firmware to install, it didn’t push through. The device just reboots but when I check the version, it was the same so the update didn’t install. Now, how can I successfully initiate the installation? Thanks for your time! — Jessica

Troubleshooting: Hi Jessica! Since it is a major update and not just a patch or update to fix bugs, there’s a few things you need to check so the installation would be successful. The first thing would be the remaining space in your phone’s internal storage. To make sure there’s enough room for lollipop, make sure there is at least 3GB of space left. Clear the cache and data of apps you don’t use and then uninstall them. If you have a microSD card, transfer all movable apps to the SD card as well as your pictures, videos and large files. Once you’ve done that, clear the cache and data of the Download Manager to reinitiate the update process:

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Download Manager.
  6. Tap Clear cache button.
  7. Tap Clear data button, then OK.

If you won’t get the notification for the update or if manual search through Settings won’t do anything to re-install lollipop, call AT&T and have the rep push the update to your phone.

AT&T Galaxy S5 Didn’t Get Lollipop Update Notification

Problem: My husband and I bought our phones together last year and we have the same model, Galaxy S5 through AT&T. I am just grateful that I haven’t experienced any problem with my phone and my husband as well. Everything was smooth so I really couldn’t be happier. Last week my husband’s phone got the notification for the Android 5 lollipop update and it was successfully installed after an hour. I was hoping I would get the notification the day after but nothing came. I waited and waited and it’s almost a week since he was notified and I’m still waiting. So, I’m a bit worried that my phone will remain running Kitkat. Can you provide a little help how to get the notification, please. — Mary Ann

Troubleshooting: Hi Mary Ann! Carriers and service providers in the U.S. more often roll out updates in batches to avoid overloading in their servers. Because of this, some users may receive update notification later than others. I understand your husband already got the lollipop update but roll outs aren’t done by area. That said, the best thing to do is wait it out because it will come for sure. Or, you may call AT&T tech support and see if the rep can manually push the update to your device.

AT&T Galaxy S5 Won’t Light Up After Lollipop Update

Problem: Hi droid guy! Thank you so much for spending time reading my email and providing solution to my problem last time. Now, I have a new issue that I couldn’t figure out. The lollipop update came (yeah, it was late but, at least, it came) and I downloaded it successfully. Now my phone runs Android 5 and so far, so good! There’s, however, one problem–the soft keys to the left and right of the Home button don’t light up like they used to. I noticed this immediately after the update so I’m thinking maybe lollipop ruined it for me or there could be just a setting that was changed during the problem or a feature that is restricted. But whatever it is, I just don’t know where to look. Can you guys help me out one more time, please. — Jam

Troubleshooting: Hey Jam! We’re happy to know we helped you fixed your problem in the past. About your recent problem, it seems like the Power Saving Mode has been triggered during the update. You’re not the only one who encountered this problem after the lollipop update. The fix is to disable Power Saving Mode and that’s it!

  1. From the Home screen, touch Apps.
  2. Tap Settings.
  3. Scroll to and tap Power saving mode.
  4. Touch the slider to Off.
  5. Power saving mode is now off; the soft keys should light up now.

I hope this helps, Jam!

AT&T Galaxy S5 Stuck On Recovery Mode After Lollipop

Problem: Hi Harold! I enjoyed reading your posts on Galaxy S5 problems. I already read some problems related to mine but I just want to know if the troubleshooting procedures for the international version of the S5 will work on mine, which is branded with and getting its service from AT&T. The problem started just after I installed the latest update, which was lollipop I think. After the installation, the phone rebooted just like when I updated it to Kitkat a few months ago. I thought everything was normal but it got stuck on the recovery mode. I tried boot it up again but it was still stuck in the Android recovery screen. Now, I don’t know what to do to fix this. Oh by the way, there are times when it shows the Samsung logo then got stuck on a black screen, but not recovery. So, my problem is the phone won’t boot up normally. Can you help me fix this, please? — Jeremy

Troubleshooting: Hey Jeremy! If the phone got stuck after the logo, then do the soft reset first. Just follow these steps:

  1. While the phone is on or stuck, remove the battery.
  2. Press and hold the Power key for a minute to discharge all stored electricity.
  3. Replace the battery and then the back cover.
  4. Turn the phone on to see if it can boot up normally after that.

If the phone failed to boot up normally, then you have no other choice but to wipe out the cache partition. Here’s how:

  1. While the phone is stuck on that screen, open the back cover and pull the battery out.
  2. Press and hold the Power button for a minute to drain all stored electricity in the capacitors.
  3. Place the battery back in and then the back cover.
  4. Attempt to turn the phone back on.
  5. If it still boot up in Recovery Mode, highlight the ‘wipe cache partition’ option using the Volume Down key, then the Power key to select it.
  6. Reboot the phone after that and everything must be back to normal now.

AT&T Galaxy S5 Lags Like Crazy After Lollipop Update

Problem: Hello guys! I am very, very disappointed with the recent lollipop update because it ruined my phone for me. There was this notification telling me I have to download a firmware upgrade, so I did and it went smooth with no problems whatsoever. However, after the installation my phone started to lag and freeze like crazy. Imagine that I have to wait a minute before I can use the messaging app or check my email because that’s how slow the phone in loading apps, even those that are light in nature.

There’s also these error messages that keep popping up every time I open some apps. For example, when I open the video player, there’s an error that says it has stopped working. The same thing happens when I open settings. So, basically, I can’t use my phone like I used to because of the lag and error messages. Your help will be much appreciated. Thank you! — Janice

Related Problem: Hello, I’m kinda hoping maybe you could help me with my cell phone problems as they seem very similar to the ones being experienced by Note users, first hand let me tell you any help will be greatly appreciated. Ok so my problem is lag, I have the Samsung Galaxy S5 from AT&T, until 2 weeks ago I was running Kit kat 4.4.4 but then one day the upgrade to lollipop came, the upgrade went smooth no problems but since then the phone lags no matter what app I use. I’ve cleared caché on my apps but nothing, I’ve removed others still the problem remains, I’m thinking a master reset maybe but first I thought maybe you could give me some advice. Once again thanks for your time hopefully you can help me. — Raul

Troubleshooting: Hi Janice, if the installation was successful, then some data or caches may have been corrupted after the update. You need to delete those corrupt files so the phone will be forced to create new ones that work. To do so, all you need to do is perform full hard reset. But then, of course, your data will be deleted if you did that. I suggest you boot your phone in safe mode first, backup your data and follow the steps below to reset the phone.

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

AT&T Galaxy S5 Can’t Send MMS After Lollipop Update

Problem: I just notice that for three days since I updated my phone’s firmware to Android 5 it can no longer send/receive picture messages. I tried attaching a photo to my text message just a few minutes ago but it didn’t send. I asked my friend to send an MMS and it didn’t went through. I mean, my phone hasn’t received it. It is actually the first problem I encountered in months so I’m clueless on what to do. By the way, I am with AT&T now but I bought my phone somewhere else. I remember I had to call my provider before so I could use MMS. I am planning on calling the tech support number but I just want to see if you guys can help me before I stay on the phone for several minutes. Thank you. — Jorge

Troubleshooting: Hey Jorge. Well, it seems like the recent update messed up or deleted the APN in your phone. It’s common for phones that didn’t come from your service provider because they aren’t programmed to connect to the network by default. That’s why your provider’s intervention was necessary so you could enjoy the MMS feature of the phone.

While there are hundreds of websites that show the APN settings for AT&T network, I still recommend you call your service provider and ask for the correct or update APN settings for your phone just to make sure you got everything correct. You may also ask the representative to walk you through setting it up in your phone again.

The APN is a set of data or characters that you need to enter to your phone so it can connect to the mobile data network and enjoy whatever service your provider providers. Again, it’s just about the APN and nothing else.

AT&T Galaxy S5 Freezes Every Time Home Button Is Pressed

Problem: I have a really strange problem and I don’t know if the recent update caused it but it might have. The issue is every time I hit the Home button, the phone goes back to the Home screen then it freezes and stops responding after that for a few minutes. When it finally comes back to life, I can use the phone normally like open apps, make a phone call, send a message and emails and everything but when I hit the Home button again to go back to the Home screen, the phone freezes again. It’s annoying, really annoying. So, I will really appreciate all the effort you exert in helping fix this problem. Do you think there’s a problem with the Home button? Thanks!

Troubleshooting: It may appear like there’s a problem with the Home button but it reality, it’s not the hardware that has an issue, it’s the software and specifically Samsung’s proprietary launcher, TouchWiz! You see, the phone goes back to the Home screen when the Home button is pressed. That’s a sign the button is fine. The reason why the phone freezes is because the recent update messed up some data or cache used by Touchwiz. By the time the phone is requested to access the Home screen, Touchwiz goes crazy due to corrupt data. Consequently, the phone lags or freezes. Then after a few minutes the device will function properly until the problem is triggered.

To fix this, all you need to do is clear the cache and data of Touchwiz:

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Touchwiz.
  6. Tap Clear cache button.
  7. Tap Clear data button, then OK.

Apps Greyed Out After Lollipop Update on AT&T Galaxy S5

Problem: Hi guys I’m John, the issue of my Galaxy S5 started when I updated its software to lollipop. After an hour, I noticed that some of my apps that I previously installed is not working or “greyed out”. And when I clicked one of the “greyed out” apps the message will show up saying that the apps need to be installed. Do I really have to install back those greyed out Apps? Thanks and more power!

Troubleshooting: Hello John, if those apps were moved to the microSD card prior to the update, then it’s actually more of a microSD card issue than a software problem. To further check the issue, unmount your SD card and let it be read by PC or laptop to make sure that it’s not defective, damaged or corrupted. If it happens that your SD card cannot be read by your computer, then your SD card may have been corrupted and that’s the reason why you’re having an issue like that.

If your computer asks you to reformat the card the moment you insert it in, then there’s a very slim chance you can recover your data in it. If the microSD card is corrupted, you can reformat it and mount it back to your phone. If it’s damaged, then you need to buy a new one and redownload all those greyed out apps.

However, if those apps were installed in your phone’s internal memory, then all you need to do is reboot your phone until all those apps are optimized. After that, they will all be working again.

AT&T Galaxy S5 Alarm Won’t Work After Lollipop Update

Problem: Hi, last week I updated my Galaxy S5 to lollipop and my phone is working great. But just this week, I noticed that the device’s alarm won’t work or doesn’t ring at all. Please help! – Ethan

Answer: Hello Ethan, regarding your issue most of our readers have also the same issue after they updated their phone’s software to lollipop. However, the issue was caused by so-called “Priority mode or Interruption mode”. This certain feature controls the sound and notification of the device in which, the Priority mode was enabled only to “Priority”. Meaning, your device will only ring if there’s a call or important notification is coming and that’s the reason why your alarm clock is not working. To make the alarm clock work, you can configure the Priority Mode feature and set to “All” instead of “Priority”. To Enable it you can go to Menu> Settings> Sound and Notification> Interruptions.

AT&T Galaxy S5 Keeps Disconnecting From WiFi

Problem: Good day, I have this Galaxy S5 for 3 months now but after I updated it to lollipop my Wi-Fi is not working very well. Most of the time my Galaxy S5 keeps on disconnecting and connecting to my home Wi-Fi and I can’t fix it. I rebooted my phone several times but the issue still happens on the device. Any help will be appreciated! Thanks! – May

Answer: Hi May, I understand your issue and I know it’s very annoying. But don’t you worry it’s just a minor one and you can fix it in just a few taps here and there. The Galaxy S5 has a feature that automatically scans available networks in the area and will connect to the more stable and strong signal. To fix it, you can choose two options: you can turn off mobile data completely or prevent the device from switching over to any available networks in your area.

I suggest you disable the feature that will automatically scan available networks because mobile data is important especially if you will be sending MMS or picture messages.

To disable the feature, just follow these steps:

  1. From Home screen, Tap Apps.
  2. Tap Settings.
  3. Tap Wi-Fi.
  4. Now, make sure the Smart Network Switch box isn’t checked.
