Problem #1: Galaxy S5 camera app won’t focus properly

My problem is intermittent focus failures that make for a fuzzy image. It works less than 20% of the time. It can’t focus properly at short or long ranges. Long before, I broke the square protective lens but it still could focus sharply at the center of a subject, where the hole in the lens was, but not at the edges. Finally, I replaced the lens, but I also upgraded to Lollipop. To be honest, I do not remember if the focus problem began immediately after Lollipop, but I do know I never had the problem BEFORE lollipop.

I tried everything you suggested:

-rebooted to the screen that allowed me to wipe the phone’s cache.

-cleaned the lens and the new square lens protector that I replaced. I double-checked in case a protective film remained.

-I tried it after booting into safe mode.

-I tried another camera app

-I wiped the camera app cache

-I removed the outer protective lens entirely.

I have not yet done a factory reset yet, in case you might suggest something short of that.

Can I delete the camera app and reinstall it? If so, where can I go to download the OEM camera app?

Thx for any suggestions you might have. — Kwame

Solution: Hi Kwame. Please do a factory reset to see if that will make a difference. If the issue lies on the firmware, restoring all phone settings and functions back to defaults via factory reset should fix it. Otherwise, you can say the problem is due to bad hardware.

Factory reset will also reset the current camera app version into its factory version so you don’t need to manually install the camera app APK.

For easy reference, here are the steps on how to do a factory reset:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and 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 ‘Yes — 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.

Problem #2: Battery drain issue on Galaxy S5 after Marshmallow update

How can I remove the Marshmallow update? I got the update on Saturday, and it’s killing my battery. I did a soft reset and wiped the cache partition, and I’m seeing my battery drain as I use it! It’s a new Samsung battery and held a great charge with Lollipop, but since the update I’m only getting a few hours of normal use. Just writing this question, it has already dropped by 10%!

A few other annoying problems with settings and getting my phone to accept fingerprint to unlock it now, but overall, I’m not happy at all with this update and would like to remove it. I’ve had this phone for 1.5 years, and it was one of the best I’ve ever owned, but not any more! Can you help? Thanks in advance! — Kathleen

Solution: Hi Kathleen. If the update was “pushed” by your carrier to your device, i.e., you received a notification for available update and downloaded the files, then there’s no way to revert back to Lollipop unless you do it manually. If wiping the cache partition did not help, we recommend that you also try to do a factory reset. This will ensure that all apps are installed back to their original state.

Once you’ve done a factory reset, make sure that all apps are updated. Bear in mind that updating the operating system does not necessarily mean the apps are updated as well. Apps that are not optimized to work with Marshmallow can be problematic and issues due to incompatibility may manifest in different forms including faster battery drain, freezing, app crashes, slow performance, to mention a few. An app that works well with Lollipop may no longer work properly with Marshmallow on the same device. If you have plenty of apps, make sure that all of them are updated for Marshmallow. You will usually find update information of an app in its Google Play download page. If you can’t find any indication that it’s ready for Marshmallow, make sure to remove them.

If you still want to install Android Lollipop, we recommend that you look for reliable online guides via Google. Manually flashing a ROM/firmware is risky and can potentially convert your phone into an expensive paperweight. Do it at your own risk.

Problem #3: Galaxy S5 “ has stopped” error

Hi. I have been using my S5 for more than a year without any issues. About a week ago, a message appeared “ has stopped”. I restarted the phone by taking the battery out because it couldn’t be restarted otherwise. After that the message appeared again and the phone keeps restarting with the Samsung logo then the message began appearing again and again.

I tried to reach safe mode fast before the phone restarts itself then I restarted the phone again. This worked well and the phone started normally but then all the apps are not there and nothing in the phone runs except for Whatsapp and Facebook apps. The camera is not working and cannot run from the home screen. Videos don’t run and no gallery icon found although I can send and receive images from the Whatsapp but received videos cannot run. I wiped the cache partition but nothing happened. Apps are found in the application manager showing 0.00 bytes.

Please help me as I cannot backup my phone data because usb cables don’t read the phone in the PC and no backup app can run. —  Hazim

Solution: Hi Hazim. There’s no more effective solution to your problem than a factory reset. If you need to copy your files to another device, try booting the phone in safe mode, connect it to a PC, and create a backup.

The “ has stopped” error is an indication that one of the important services does not run properly, most probably due to a third party application. If you have a lot of apps, or if you can’t figure out which of your apps is problematic, doing a factory reset is the first important step towards resolution. Before you do a factory reset, make sure that you disable Automatic restore option under Backup and reset section. This will prevent the phone from re-installing the same set of apps after a factory reset.

Now, since we think the problem is caused by one of your apps, we recommend that you invest more time in observing how the phone behaves after re-installing a single app. If the issue returns after installing an app, that’s an indication that the new app may be the cause.

Problem #4: Galaxy S5 screen moving up and down when using apps

Hello and thanks for this free asking form you’ve created.

It’s been about 2 months now that i have the following problem with my phone. When typing on WhatsApp, Viber, Facebook, etc, for the first 5 minutes, everything’s ok. But then, the screen starts something like moving up and down…the keyboard goes on top of the screen, or half of it goes up and the rest stays on the bottom. If i want to type, i have to type where the keyboard SHOULD HAVE BEEN. so i learnt where i should type till the keyboard comes back to normal. It was only a screen issue.

Recently, when that happens, i cannot scroll down the screen, stays frozen, doesn’t respond, and sometimes, even though the phone is working perfectly (receives calls, messages etc), the screen is black and stuck. When i reboot my phone everything’s works fine for another 5 min and then the problems starts right again.

I’ve tried uninstalling the apps. I don’t use Facebook apps but via Google Chrome. I have deleted the cache, some photos, but the problem seems to persist after every minimum automatic update. Can you help me please? — Nikos

Solution: Hi Nikos. It’s interesting to note that you haven’t tried observing how the phone behaves when it’s on safe mode. We think that one of your apps is to blame for the problem so restarting the S5 in safe mode is the next logical step to do. While on safe mode, no third party apps will be allowed to run so if the problem fails to occur, that’s a confirmation of our hunch. If you haven’t tried to boot your S5 in safe mode before, simply follow these steps:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

Most software or app issues can be fixed by factory reset. Don’t hesitate to do it if nothing changes even when the phone is in safe mode.

Problem #5: Galaxy S5 no longer powers on

Hi. I have a Samsung S5. This morning I had an message so I opened it and the phone crashed so I left it for a few minutes hoping it will sort itself out but instead after a few minutes the phone decided to turn off and refused to turn back on even with a fully charged battery. I’ve tried all the usual ways to turn the phone back on like pulling the battery out and with and without SIM and micro SD card. Still nothing.

I’ve also tried the factory reset and still nothing happens. It’s completely dead not even a flash or a vibrate. Nothing works at all. I rely on my phone for work mainly but also family and friends cause it’s the only phone I have. I don’t have the money to take the phone to the shop to be fixed so please could you help me.

Many thanks. — Lee

Solution: Hi Lee. An issue like this can be caused by hardware failure or software glitch. If you have access to a new battery, we recommend that you try using it to see if battery is the issue. Lithium-based battery can sometimes fail for no reason, so using another known, working one may actually work.

Another good thing to try is to see if you can boot the phone in other modes (safe mode, recovery mode, download mode). To boot in recovery mode, please follow these steps:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and 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.

If you can boot your device in recovery, that means that you can do two important troubleshooting steps — wiping the cache partition and restoring the defaults via factory reset.

To boot in download or Odin mode, simply turn the phone off, then press Home, Power, and Volume Down keys at the same time.

If the phone is totally unresponsive after doing the procedures, consider having it checked for repair or replacement.

Problem #6: Galaxy S5’s screen is black and won’t respond

The phone worked fine a couple of days ago. And then yesterday, I was using it (4/9/16) and all of a sudden, the screen is completely black. And all it will do is beep when I plug it in, and make the lock screen sound. And the only light that shows up is the charging light, which is red (I’m guessing due to a dead battery.) And the buttons that light up blue on both sides of the center home button. My phone was bought as a Christmas gift just this past year (December 2015) and was bought used. The phone has worked fine until yesterday, as I said above. I’ve read your article on the black screen problem and tried your solutions, and nothing has worked. I thought also that it could be a burnt out LED bulb on the screen which has happened on my previous device, but you could still see the apps, but just barely. And on my S5, it’s completely black, like it’s shut off.

Also before I forget, I guessed above on the Android Version software, because I honestly don’t know what software it has, if that helps any? Thank you! — Brandon

Solution: Hi Brandon. The red LED light on top of the screen is an indicator that your device charges fine and that the battery is probably fine as well. Most of the time, a black screen issue can sometimes be a result of hardware failure. If you dropped the phone before or got it wet, there’s a big chance that one of the three major components of the screen assembly — LCD, digitizer, or flex cable — has been damaged. Unfortunately, diagnosing a screen issue cannot be done by doing software troubleshooting. You have to allow a professional do it for you.

  1. Sprint Galaxy S5 – updated to Marshmallow yesterday, battery life today TERRIBLE! I’ve never had a battery issue before with this phone – could easily make it through 10-12 hours of mixed use. Today I was busy and barely used the phone at all, battery drained by 50% in 5 hours!!!
