Phone won’t boot up completely
Problem 1: Hi, I had this same problem since last night. My phone had 85% battery and it turned off all of a sudden randomly. now i cant get it to turn on. It only loads the Samsung screen and the Galaxy S3 symbol. When I put the charger, though the home screen comes up with all the apps but it neither indicates that the charger is plugged nor the phone is charging. Please help.
Problem 2: Hi there, my Samsung s3 simply just turned itself off last night and refuses to turn back on. When I remove the battery and turn it on the Samsung logo just repeatedly keeps flashing and it does nothing else. Is there anything I can do to fix it? Many thanks. — Natalie
Problem 3: Hi, I was looking for some help on my galaxy phone, it keeps freezing on me. I have already tried taking out the battery and putting it back in again, but this is not working. When I do this the galaxy start up screen appears, and this is when it freezes. What do you suggest I do? — Padraig
Solution: I just want to make things a little clearer here; the phone turns on, it just wouldn’t boot up completely. There is a big difference between the two; the former could be a power problem while the latter may be a firmware issue.
I have encountered this problem a lot of times already and it could either be a very simple problem or a complicated one. When troubleshooting, we have to take into consideration all factors starting from simple ones and that’s what we’re going to do.
- First and foremost, I want you to pull the battery out while the phone is on. Then press and hold the power key for a minute to discharge off electricity from capacitors. Then, place the battery back and attempt to turn the phone on.
- If the first procedure won’t fix the problem, boot the phone to Safe Mode just to find out if it could. If the phone boots up in Safe Mode, there is a big possibility a third-party app is causing the problem.
- Now, if your safe mode attempt won’t work, try booting the phone to recovery mode and if that’s successful, you can wipe the cache partition and perform factory reset. At this point, you may lose all your data save in the phone’s internal memory.
If you don’t want to perform factory reset, bring the phone to a technician and have check the phone for possible hardware problem.
MHL connection shows black screen
Question: Hi, I have a Samsung MHL 1st generation. I connected through HDMI to my Samsung S3 and TV but I only get a black screen. Could you help? Thanks.
Answer: I’m not really familiar with the 1st generation of Samsung MHLs but if there’s a spare port that’s unused on it, use your phone’s power adapter to power the MHL on. As far as I know MHL 2.0 doesn’t need a power adapter to be powered on because the phone itself will provide the power needed. A power adapter could be just what you need to make screen mirroring work.
Can’t get mobile data to work
Problem: Yes I have a Verizon Samsung Galaxy S3 and can’t get my data to work. Please help.
Solution: Please call Verizon and ask for the correct APN. Then have the rep walk you through setting it up or editing existing one on your phone.
Can’t update 4 apps after firmware update
Problem: Hi, ever since I migrated to Android 4.3, some apps that I had no trouble with before started giving me error messages every time they attempted to update. I have many other apps running updates without any problem, but those 4 stubbornly will not update, and I get a message that I will loosely translate in English (my phone runs the French version of Android). The problem remains as I recently received and installed the O/S update to Android 4.4.
The error message says: “It is impossible to proceed to the installation on the USB memory storage, nor on the SD card”.
The handset comes with a standard 16GB internal storage, of which 3GB are currently available. I have inserted a 32GB uSD card, of which 24GB are available.
I have attempted time and again to free up RAM and try the update right after, with no success. I do not understand why those 4 apps behave like that, while all the others update normally. Can you explain what happens, and how this problem can be fixed? Best regards, Marc.
Solution: You could have been more specific and told me what those 4 apps are so I could provide specific explanation and probably try those apps with my devices. But not all apps from t he Play Store are compatible with the latest firmware–I’m seeing that as one of the factors.
If the problem occurs every time those apps attempt to update, then uninstall them and download the new version from the Play Store; it works every time.
I encountered an issue before wherein I couldn’t update an app so I uninstalled it and downloaded the latest version from the Play Store; it would install. I boot to safe mode and tried installing while in that state and it went through.
There are times when problems happen to our device that we cannot explain. So, if you cannot install the new version of the app after you uninstalled it, try booting to safe mode as well and attempt to install it from there.
Phone reboots when uninstalling apps
Problem: Hi, I have the Galaxy S3 and it keeps restarting whenever I uninstall an app. I’ve tried clearing data from a lot of apps, Trying to uninstall from safe mode and even factory resetting it but the problem is still there. If there is any way to fix it please let me know. Thanks in advance.
Suggestion: That’s weird, I never encountered a problem like this before. Are you getting some kind of errors when uninstalling apps? How about random reboots? Have you noticed the phone rebooting even if you weren’t uninstalling apps? Let me dig on this problem first and I will email you with my findings.
By the way, if the problem only occurs when uninstalling apps, then it’s not really a hassle unless you have a habit of installing a lot of apps and uninstalling them after. I’m also wondering what kind of apps you install and uninstall. But don’t worry, I’ll keep researching on this problem.
Callers hear echo when in a call
Problem: Dear I’m Faisal from Pakistan, I just buy US model of Samsung Galaxy S3, I got one issue with it, when someone makes call to me, I receive proper and smooth voice, but the caller claim when they do make call to me, they received feedback voice of their own, please tell me how to fix… Please help me. It’s humble request.
Solution: This isn’t a new problem with the Galaxy S3. Ever since it was released in 2012, there were a lot of users complaining about the echo their callers hear. There are three causes I know about; first, the most common is the third-party case. So, if you are using one and this problem happens, it’s better you take it off.
The second is the noise reduction feature; if enabled, there is a tendency the caller can hear echo. While in a call, hit the Menu key and turn off noise reduction. You can then ask your caller if he/she can still hear the echo.
The third one is a network issue. There’s nothing you can do about it but report it to your network provider. So, call the hotline, tell the representative what you already did to troubleshoot the problem.
Internet connection unstable
Problem: Hello. I have went through all your pages that will actually open and I cannot find a solution to our galaxy s3 problem. Ever since day one of upgrading to 4.3 I’ve experienced problems on Wi-Fi. I constantly get a message on top that says “internet connection unstable”. I upgraded about three weeks before my wife and as soon as she upgraded she stayed getting the same message. It doesn’t matter what Wi-Fi we’re using whether at home, church, or public it’s the same so I know it’s not our router. It only happened after the upgrade. Is there a solution or are we forced to deal with it like we have been? Thank you so much for all you do. — Troy
Solution: There are two ways to deal with this problem. The first one is seems obvious while the second procedure is a little complicated but I was told by S3 owners who encountered this problem that it worked.
The first procedure includes forgetting the network and refreshing Wi-Fi:
- From the Home screen, tap the Menu key.
- Tap Settings.
- Scroll to and tap Wi-Fi.
- Long press the network you’re connecting to.
- Tap Forget Network.
- Tap the Menu key again.
- Choose Advanced.
- Turn Auto Network switch to Off by unchecking the box.
The newly discovered fix for this is the usual cache partition wipe…yes, it works.
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up, Home and Power keys.
- 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 and wipe the cache.
- With ‘reboot system now’ highlighted, press the Power key to restart the device.
Alarm not working, phone keeps shutting down
Problems: Hi there, I have a Samsung Galaxy S3 which I bought about 18 months ago.
My service provider (Telstra) issued an update to Android Version 4.3 which I installed.
The only issue that I am now having is that when I charge my phone, it turns off when it reaches 100% charge. Not good when you use it’s alarm function to wake in the morning. Also not good when I am on call and no one can reach me because my phone turns itself off. Any ideas on how to fix this issue? Any help would be greatly appreciated. — Glen
Suggestion: Hey there, Glen. It’s probably just a glitch caused by the recent update. It happens a lot of times that after the update the phone manifests several issues and it’s often because of some data that were corrupted during the process. But the thing is we don’t know for sure what causes all these. Therefore, the best course of action is to use broad troubleshooting procedures and in this case it’s wiping cache partition and Factory Reset.
Can’t clear cache of apps
Problem: Hi, I’m hoping you have some advice for the issue I have now after updating today on Galaxy S3. 4.4.2. Since this update it won’t let me clear the cache on apps. Any suggestions? Thanks so much, Valerie.
Suggestion: I’m not sure what you mean by “won’t let me clear the cache on apps.” I’ve never encountered not being able to clear app caches, although there are always two possibilities; either there isn’t a Clear Cache button, which means there isn’t a cache to be cleared, or it’s greyed out, which means the caches have already been cleared. If it’s the former, then you are dealing with apps or services that don’t store cache and you can rarely encounter these kinds of apps. If it’s the latter, then it means you there aren’t caches stored yet or they have already been cleared either by the owner or the system.
If you badly need to clear cache but the app won’t let you, then you can boot to recovery mode and wipe the entire cache partition–that’s the same thing, although, it’s a broad-spectrum troubleshooting.
KitKat update for Galaxy S3
Question: Dear sir, I own Galaxy S3 international version. My phone has been updated to the latest version ie 4.3 and I have not come up with any of the listed issues. My phone is working very smoothly. I have not flashed my phone till now. I am very surprised to see the listed issues with this phone.
Now I am worried that Samsung has stopped upgrading it. Is it possible that my phone will get latest kitkat version of Android? Thanks a lot, Sanjeev.
Answer: There are more than 50 million Galaxy S3 owners around the world and while we are receiving hundreds, if not thousands of emails from owners daily, that’s only a small percentage of the total number of S3 and that’s expected. Of course, there were a lot of people who emailed us asking about things that couldn’t be considered problems.
I can say you’re very lucky to haven’t encountered any of the problems we cited in our publications. About your question whether your phone will get the latest KK update, well, no. Samsung already made a statement that only the LTE variants of Galaxy S3 will receive the update due to RAM insufficiency. But then again, there are hundreds of S3 users who flashed custom ROMs in their phones so they could update their phone to the latest firmware. You may want to try that.
Phone can’t get cellular coverage
Problem: Hi there. my galaxy s3 has had no reception for the last couple of hours but I’m sitting in my own home and can get wifi. Any suggestions to help?
Suggestion: If you haven’t done anything that could have messed up the settings of your phone and if you previously were getting good coverage, then I am almost certain it’s a temporary network issue. There’s nothing to worry about because your service provider will immediately fix that as it may result to operational losses or push subscribers to seek better service. The best thing to do is to sit back and relax and wait for the problem to be fixed.
However, if you have messed up your phone’s settings, you must remember the setting that worked, otherwise, it is necessary to perform factory reset just to bring the phone back to its default settings.
