Why Does Android Randomly Restart?

Why Does Android Randomly Restart?

By 40 Comments

A common question Android users may ask is “Why does my Android randomly restart itself?” At one point or another, every Android device I’ve owned has had this problem. There are a few common reasons your Android might restart on its own. Let’s take a look at them and see if we can fix it.

Cause #1 – Bad Apps

In most cases, random restarts are caused by a poor quality app. Try uninstalling apps you don’t use. Be sure the apps you do use are reliable, especially the apps that handle email or text messaging. My wife recently discovered her Galaxy S5 would restart sometimes when receiving a text message. Switching from the Verizon Messaging app to Hangouts for text messaging fixed that issue.

You may also have an app running in the background that is causing the Android to randomly restart. When a background app is the suspected cause, try the following, preferably in the order listed:

  1. Uninstall apps you don’t necessarily need. This goes especially for any apps that control sound, ringtones, wallpaper, have fancy widgets, or use GPS.
  2. Ensure all apps are on the latest version. Upgrade everything you have from the Play Store by going to “Menu” > “Settings” > “My Apps“.
  3. Uninstall apps that run in the background. From a fresh restart, go to “Settings” > “More…” > “Applications” > “Running“. If you see anything listed you can live without, uninstall it. If you cannot uninstall it, freeze the app if possible.

Cause #2 – System Apps Are Disabled

Did you play around with disabling Android apps? If you went too far and disabled apps that are required to run the Android OS, it may be causing your restarting issue. Have a look under “Settings” > “Applications” and swipe over to the list of apps that are “Turned Off” or “Disabled” and enable any apps that may be needed for your device to function properly.

Cause #3 – Overheating

Many Android devices are designed to shut off automatically if they become too hot. If you have your device out on a 100 degree day while trying to use 4G, GPS, and the screen is set to the brightest setting, it might restart itself or shut down. Try to take it easy and maybe disable features you don’t need.

Overheating shutdowns shouldn’t be a regular problem though. If your device is overheating regularly, contact the retailer or manufacturer about it.

Cause #4 – Loose Battery

f course, this problem only occurs on devices with a removable battery. My Droid 1 and Samsung Galaxy S4 were notorious for suddenly restarting. Sometimes they would shut off and never turn back on. It turned out that in both cases, the battery was coming a bit loose. Just a slight jab at the device would quickly unseat, then re-seat the battery, causing it to reset.

The most common reason for this is the rear cover has become slightly bent and is no longer holding the battery into place. Another reason is the gold battery connectors are bent out of shape. Over time, the connectors may get worn down.

There are two ways to tackle a problem with a loose battery:

    1. Purchase some mounting tape, then affix a small piece to an area of the rear cover so that it holds the battery into place better.
  1. Turn the device off, remove the rear case and unseat the battery. Locate the battery connector pins. If possible, use a small screw driver to pry the connectors into a position where they will make better contact with the battery.

Cause #5 – Corrupted System Software

metimes the Android system software gets corrupted. If you are using a custom Android ROM, try a different version of the ROM or another type of ROM altogether. If you’re not using a custom ROM, your only option may be to try a factory reset of the device. Beware though, a factory reset will erase data from your device. On most Android devices, you can perform a factory reset by going to “Settings” > “Backup & reset” > “Reset device“.

Cause #6 – Stuck Button

times the “Power” button can get some water or gunk stuck in it. Be sure that nothing is jammed in the button opening. Also check to make sure your case is not putting pressure on the button at all.

Cause #7 – Defective Hardware

verything above has been tried and your Android is still randomly restarting itself, you may just have a bad device. Contact the retailer or manufacturer about the problem. You may not have that option if you have a custom Android ROM installed. In that case, you may want to take your question to the maker of your particular ROM.

FAQ

ong>My Android is low on battery power and restarts when plugged in. Why is it doing this?

You are likely not giving the device enough power. Ensure you use the correct power adapter and cable and plug the Android into a wall outlet, not a computer or other device with USB ports.

  1. Samsung S6 Active – constant refreeze reboot problem. Solution: reduce CPU usage by choosing Device Maintenance and setting battery usage to “Med”.

  2. I’ve installed custom rom in my device. After using, when I keep it idle (locked) it automatically restarts mainly when I use high memory apps ( google, instagram, etc). It also automatically restarts when I use my camera, I switch on my camera, try to get some clicks and it automatically restarts!!!!… Help me with this, is there any app, Flashable zip, or anything which will work for my problem, please help me out.

  3. My S7 Edge restarts randomly. When I put my phone on charging after some time when I saw it my device says to use pin code instead of finger print as your phone was restarted. Please tell me solution .

  4. A phone with an inbuilt battery can also suffer with loose battery connections if the battery has been replaced in the past (like my S6)

    Its currently running off the mains and all thr symptoms listed for the loose battery fits right down to evem slightly tapping it making it restart. Opened it up, the cable is so loose it just popped away with VERY little effort.

  5. ATTENTION USERS!!!

    I have tried some methods to fix the problem, where our phones keeped freezing and restarting/rebooting themselves. RECENTLY SOMETHING (SAME THING) DESTROYED MY SD CARD.I found the problem AND MAYBE a solution, so listen carefully:

    1. FACTORY RESET YOUR DEVICE
    2. RUN IT IN SAFE MODE.
    -IF THE DEVICE STOPS RESTARTING ITSELF, THE REASON IS THE APP ( YOU WILL NEED TO FIGURE OUT, WHICH ONE)
    -IF IT’S STILL RESTARTING, THERE MUST BE A PROBLEM WITH A BATTERY!!

    Thank you for seeing and reading my comment and i hope, this was helpful.

  6. An app can’t make your phone restart with a background process. If you’re phone is restarting, the problem is with the OS. Please don’t spread misinformation when you don’t know what you’re talking about.

  7. Okay, so my LG G4 is almost brand new and it will shut down in my pocket while the screen is just off. I’ve factory reset it and that works for a while but then I’ll shut it down once and then the issue comes back. I don’t have any sketchy software installed and hardly any apps at all. I’ve searched through so many websites and forums to fix it. Does anyone know how to fix my problem?

  12. I have an android 6.1.1 (I think) it did a “soft reboot” I was on 70% in a system app called “google account update” then I found out it’s sorta like a web view I started useing it like it was a true web view app then 2 or 3.5 minutes later, it preforms a “soft reboot” this is my first time seeing an automatic soft reboot I forced soft reboots on my lg 5.1.1 with root on it. But this is different, was it the app “google account update” being abused as a web view?

  13. Hello!
    My LG-E975 ran pretty smoothly for past 5 years, but since last week it randomly restarts, both when i use it, and when i don’t (standby). When it does restarts, it doesn’t ask for PIN code, as it would in normal restart. I keep my apps to minimum, just essential ones. I guess this started because of recharging in a car, using 2.1 V charger for the first time.
    Could it be, this charging in a car made damage to the battery? Can it be fixed (by factory reset exp.)? Or is this phone too old and just showing its wear?

  25. DO NOT pry on the battery contacts! I can’t even begin to tell you how many phone I have repaired in a workshop that people destroyed the contacts on. I have yet to see a phone where the contacts are the culprit for reboot issues.

  26. Hey guys, my Lenovo does the same thing as Rajat posted (pls see his comment). After two months, somehow it decided to wake up. It looks/looked perfect, but this morning it started to do that endless rebooting again. However, this time it decided to turn on, keep functioning normal for a while, and then get into that routine again. It must be a common problem with Lenovo (No more Lenovo again!)

  34. IT WORKED FOR ME. Though factory reset was the worst option I could think about it helped…Thanks for reading this comment!

  35. My Innjoo i2s has been going off and on lately. Sometimes I plug it on when phone is down and I see 99%. Changed battery yesterday and still same thing. Now I’ve been charging for over 30 minutes and it’s still on 1%. What do I do? If I try making or receiving calls it goes off and reboots. Sometimes it goes off and never comes on making the phone to overheat.

  36. what if a factory reset does not solve the problem? Is there any way to check for missing or corrupt files Within The Android operating system? Sort of like a scan disk that Windows used to use? My phone now Works but it only sort of works if that makes sense. I don’t have many apps running on it and ironically, when it was working perfectly, I probably had about 135 apps. I probably now have something like 25. I have no malware, viruses or anything malicious on the phone. All of my temporary junk files and cache has been deleted. It’s an LG G3 running Android 5.0.1 that worked absolutely Flawless for a little over two years and now is not working. Occasionally it’ll take 5 minutes to boot from the logo screen but sometimes it only takes 20 seconds. Other problems include apps that never load past the background colors. And sometimes, when I turn it on there’s an exclamation point where the data connection signal should be. Help! I probably put in a good 24 hours worth of work on this phone

  37. My phone isn’t working properly. It is just showing two three seconds of boot animation and it looks like this same is put on loop. It never finishes its booting operation and just keep on rebooting itself. First it shows company’s logo and then the model name and this happens again and again. It itself when it consumes all the power.

  38. Hi . my lenovo s850 keep restarting again and again and again until i plugged in the charger even when my battery is 100% . pls help .

  39. I reset my phone for the first time, and it still cannot fix my phone…and I reset my phone with no memory card inside my phone for the second time, it fixed my phone and it works well now. I format my memory card to ensure that there is nothing left in my memory card to avoid the same problem happened again

  40. my nokia xl is restarting everytime after a service sometime it works upto 20 minutes sometimes it switch off at the time of booting itself normally it works for more time when the battery charge is below 50 percent????
