Randomly powers off even with full battery. Have to take battery out and back in to be able to get it to come on. That doesn’t always work so I’ve started taking battery out for at least a minute and pressing home key that minute its out. then I put the battery back in and press power button. it will start and so far that has always worked, no matter the charge.
when i go to bed at night it will always goes off sometime during the night. i never wake up to my phone on. Sometimes it will shut itself off I’m not sure if it’s off or in sleep mode because little blue dot of a light will be on flashing. I always think that’s the network.
i tell you i love this phone as far as what it’s supposed to be and i really want it to work properly but now as it stands I’m ready to take a hammer to it.
well i did follow the suggestions. i downloaded the advanced task killer and so far so good. i was shocked to see when returning to my desk after lunch my phone had not shut itself down. thank you so much for your time and will be awaiting your intellectual advice. — Kimmaly
Solution: Hi Kimmaly. Random reboot issue on any smartphone can be caused by one of many factors. Knowing the cause of the problem in your case will not be straightforward so you have to do some troubleshooting. Below are the things that you can try:
Boot in safe mode. An average user usually install a minimum of 40 third party apps at any given time so it’s tricky to know for certain if one of them is causing a problem. The only effective way to check if a third party app is to blame is by booting an Android device in safe mode. Doing so will not pinpoint the exact offending app, but it will, at least, give you a point to start. If the phone works normally and won’t restart on its own while on safe mode, you can assume that one of your third party apps is the problem. Make sure that you observe the phone for at least 48 hours so you’ll notice the difference. To boot the phone in safe mode, just follow these steps:
- Turn off the phone completely.
- Press and hold the Power key and the Volume Down key.
- When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
- Safe mode will be display at the lower left corner; you may release the Volume Down key now.
Do a factory reset. Another potential solution that you can try is by wiping the phone clean thru factory reset. What it does is reset all settings to defaults and delete all third-party and services. It is also very effective in fixing app- and firmware-related issues. Before following the steps below, make sure you’ve made a backup of you important data.
- From the Home screen, tap the Apps icon.
- Launch Settings and scroll to ‘User and Backup’ section.
- Tap Backup and reset.
- If you want, you can tick the checkboxes next to Automatic restore and Back up my data.
- Tap Factory data reset.
- Touch Reset device.
- You may be asked to enter your PIN or Password.
- Tap Continue and then Delete all.
Replace the battery. No Lithium-based battery, like the one on your phone, can last over a year without showing any sign of ageing or loss of performance. A good smartphone battery can start showing loss of capacity after a few hundred charging cycles. If you charge the phone at least once every day for over a year now, you can expect that your phone’s battery has now lost significant capacity to hold a charge. It would be wise for you to try replacing it at this time to see the difference.
Phone replacement. If battery replacement won’t resolve the problem, you can safely assume that there’s a hardware malfunction causing it. Call Samsung or find a way to have the phone replaced.
I got an automatic upgrade to Marshmallow a couple of nights ago, and since then I’ve been unable to send or receive mms text messages whether they are photos or, one time, a contact info card. These are things that have a download button within the text message. I can tap it and it will appear to start, but then instantly turns stops.
I use NET 10 for my service. I live in a remote area, and I normally have poor service anyway although it is about the same level of service my neighbors have with AT&T or VERIZON. There are several areas in my cabin where I can place my phone and receive texts, emails, use internet easily (phone calls not so much) — at least until a couple of days ago. I can still get emails and use internet, but making phone calls and sending/receiving mms messages has completely failed. I can make phone calls when I am away from home but I still cannot send/receive mms text messages.
I contacted NET 10 tech support last night and they sent me the new APN settings. That did not help. (Although I don’t think they asked if I had received the upgrade to Marshmallow.)
I seriously think the problem is caused from the upgrade since that’s the only thing that has changed.
Lastly, even if you can resolve this issue for me, is there such a thing as a data booster one can purchase and install in their home? Or is there an app one can download that actually works? Somehow, I’d like to be able to improve my cell reception and texting capabilities so I’m not necessarily limited to a few choice spots in my house.
Thanks so much for any help you can give me. — Sigrid
Solution: Hi Sigrid. Failure to send and receive MMS can be attributed to a number of factors. You must do troubleshooting steps in order to isolate the true cause. Keep in mind though that MMS requires that your internet connection is stable or strong enough to establish constant link to remote servers. Unlike text message, MMS needs internet connection in order to work properly. If your internet connection is spotty at best, there’s a higher chance of MMS failing to send or be received by your mobile device.
Below are the concrete things that you can try:
Ensure your inbox/sent items folder have ample space for new messages. Depending on your messaging app and settings, it’s likely that your messages inbox or outbox may be full. Be sure delete some messages from these folders before attempting to send/receive MMS again.
Wipe messaging app cache and data. Another good thing that you can do is delete the messaging app’s cache and data. Any bug or glitch may also be eliminate by doing this solution. Here’s how it’s done:
- Go to Settings.
- Proceed to Applications.
- Select Manage Applications.
- Tap the All tab.
- Choose the name of the app that has been going rogue.
- Tap Storage.
- From there, you will see the Clear Cache and Clear Data buttons.
Change network mode manually. Sometimes, system updates can inadvertently change the network mode for some reason. Although most phones are designed to connect to a mobile network automatically and to optimize connection “session” all the time, an update may change it.
Make sure to manually select the network on your phone again to see if it will make a difference. You can do that by going under Settings and manually choosing a different carrier temporarily. Once you’ve selected a different carrier, try to connect to it and wait for the error. Afterwards, dismiss the error and connect to your own network again. This should “refresh” the session and force the new network settings to take effect.
If MMS continues to fail when sending or receiving, you can assume that the issue is due to weak signal in your area. Try going to a place with a known, strong signal and attempt to send and receive MMS again.
For your second issue, the answer lies not in installing an app or software but rather in installing additional hardware. There’s no amount of apps or software that you can add or do in your phone to improve data connection speed or cellular signal strength your device is receiving. If you really want to improve the signal coverage in your place, try calling your carrier to see if they can install a signal booster. This is a specialized hardware that needs to be placed in your house to amplify the signal reaching a certain area. It works the other way around as well by amplifying the signal coming from your phone to the cell tower. Most of the time, this hardware is not free and may be added to your monthly fee.
I read about the black screen. My phone does the first 3. However, I do know what is causing it. It’s the Marshmallow update. Samsung pushed it through before they worked everything out. I have added maybe 1/4 of the apps I used before the update, and still have problems. The problem is I have random apps shutdown. I never know which one, and sometimes I can go for a couple of days without it and then suddenly they start popping up like crazy. I have done a soft reset, factory reset, shut down the phone holding buttons and do a hard factory reset. I went to Samsung and paid to have Marshmallow flashed to my phone, twice. All that did was get a little better service from my phone company.
I called Samsung and they paid to have it sent to their repair store. They found something in the screen and replaced it. A component affecting sound and replaced it. (I never noticed a problem with those things.) I told them it was a software issue. They sent back the phone, I started it up and received, “a google app has stopped suddenly.”
From what I am reading on the internet, Samsung has messed up the Note 4. They will notice when people up their contracts and go with another manufacturer. I am ready to ditch Samsung and I used to think they made the best phones. Not really looking for a solution as I have done just about everything. Just wanted to give you some info. Thank you for what you do. — Ed
Solution: Hi Ed. You’re right. If the only change you’ve done on your phone prior to noticing the issue was to update to Marshmallow, you can safely assume that it’s indeed buggy. That means that there’s really nothing that we can do to help you. You either have to revert back to Lollipop, or simply tolerate the bugs and wait for an update to the current firmware version.
Hello guys. So here is my issue. I decided to move on from note 3 to note 4 this month but i had some issues. bought two note 4s.
The first one is running Android Lollipop international version. the issue was not so good battery life. Around 8 hours with only 2:30 min of OST and it shut off at around 15 to 20. once off it would not turn back on unless plugged to wall charger. once on almost all the time it read still 15%.
So I went through all steps on forum, tried to calibrate battery, delete cache, even factory reset. None worked, still same issue.
I returned it and got another one, this time a Sprint model with Android 6.0. Working good for a couple of days but suddenly the same story. tried everything with no luck (tried different wall charger, cable and outlet) nothing, so only choice, new battery, fully charged new battery, no problems. Tried it for like a week went down to 0% normally.
However recently i switch back to old battery on the phone just to check something and from there on its been hell. Once i changed to new battery it started acting up. Almost always goes down to 0% without issues but i had it turn off at 10% and 8% twice. The big issue is it won’t charge pass 78%, sometimes 82 or 92. I have just now it was over an hour in 78%. Unplugged phone, removed battery and on boot it showed 92. Plugged it in and would not pass. When i reduced brightness to almost 0 it went pretty quickly to 100. I know the cords and chargers I’m using are fine, the outlet is fine, so what’s happening guys? What am i missing? I appreciate your help in advance. Please reply. I love this phone but its driving me nuts!! — Alexx
Solution: Hi Alexx. Like you, we don’t really know what’s happening but it can be due to one of many factors.
The first cause can be an app. Since the problem keeps happening on at least 2 Note 4s, you must have installed the same set of apps and one of them is the culprit. Boot your Note 4 in safe mode and observe it for at least 48 hours. Because third party apps are prevented from running while in safe mode, it should help you determine if our hunch is correct. If the issue won’t occur during the observation period, you can bet one of your apps is problematic.
Another factor can be software in nature, especially the power management function of the operating system. Try to recalibrate the battery again and see if it makes a difference.
If that won’t change the situation, do another round of factory reset and observe the phone again for 48 hours (without the apps).
Finally, consider having the phone and/or battery replaced.
