Android Marshmallow problems and how to fix them

Update: Two new problems with solutions

Android Marshmallow is the complete package: it looks good, and there's real substance beneath the surface. With new features and options galore, the Android 6.0 Marshmallow update unfortunately brought a few bugs along for the ride. With that in mind, we rounded up the most common Android Marshmallow problems and the solutions for fixing them.

Marshmallow Wi-Fi battery drain

This is an interesting problem, mostly because it is a case of the boy who called wolf. A lot of Marshmallow users have been posting screenshots of their battery usage page, which show Wi-Fi to be the biggest battery drain on Marshmallow. In many cases, that's just false reporting, and the device's battery life is actually unaffected by Wi-Fi, but some other users are seeing the same data and it is affecting their battery.

Several solutions have been suggested for this Marshmallow problem. The first is to go to Settings > Backup and reset > Network settings reset to clear all your connection data. This includes Bluetooth and cellular data, so you'll need to reconfigure everything afterwards.

You can also try disabling Wi-Fi scanning in Settings > Location > Scanning (via overflow menu). This function can be scanning in the background even if you have turned Wi-Fi itself off. Other people have had success simply by going to Settings > Location > Mode > Battery saving.

Some extremists have suggested a full factory reset, followed by flashing the factory image, followed by another reset through recovery. Others are factory resetting and starting a fresh install (ie not using Tap & Go to set up your old device) and then reconnecting to Wi-Fi. Personally, I recommend figuring out whether what you're experiencing is bad reporting or a real problem before you attempt any of these fixes.

General Marshmallow battery drain

Besides mysterious battery drain there's also legitimate battery drain, a staple of Android updates since time immemorial. Well, since 2009 anyway. The quickest solution to fix battery drain following an Android update is to update your apps (so that they are compatible with the new Android version) and then wipe the app and system caches to clear out old data.

You can clear app caches individually or as a whole by taking the following routes: to clear them individually, go to Settings > Apps > select app > Storage > Clear cache; to clear all app caches simultaneously, go to Settings > Storage and USB > Cached data > OK.

To clear the system cache, turn your phone or tablet off and then press Power and Volume Down until you see the Fastboot menu. Use the volume buttons to highlight Recovery and press the Power button to select it. If you see the robot on its back, hold Power and press Volume Up once to access the recovery menu. Use the volume buttons to select Wipe cache partition and press Power to confirm. Once you've wiped the system cache, you can reboot and your battery drain problem should be solved.

If your battery drain still persists after clearing the caches, the only step remaining is to factory reset your phone. First, back up everything on your Android and make sure all of your important files are safe. Then, go to Settings > Backup and reset > Factory data reset > Reset phone > Erase everything. If the problem continues even after rebooting and restoring your data, try to re-flash the Marshmallow firmware. See our guide on how to manually install Android Marshmallow for guidance.

Marshmallow installation problems

If your phone hangs up during the installation of Marshmallow, the best option is to wait. Sometimes the first boot after an update takes a long time. If it's still hung up a long time later, you can wipe the system cache through Recovery mode, using the steps outlined above. Restart and attempt installation again. If the same things happens, you'll have to back up your data and factory reset before trying to update again.

Marshmallow Wi-Fi connectivity issues

If you're getting spotty Wi-Fi connectivity on Android Marshmallow, there are a few things you can do. First, try toggling Airplane Mode on and off. If that doesn't work, turn off Wi-Fi, reboot your phone and turn it back on. Next, forget the connection and reconnect to it. Finally, go to Settings > Backup and reset > Network settings reset.

Marshmallow stability and performance issues

Not all updates are perfectly stable in the early days. That's why Nexus folk get them first, so they can find the bugs and report back to HQ before everyone else gets them. That's not really true, but hopefully it makes early adopters feel like they're performing a public service when dealing with new update problems on Android.

If you find that your version of Marshmallow is unstable – random reboots, app crashes, glitches and stutters, strange behavior and so on – then you have a couple of options. Simply turning your phone off for a minute before restarting it might fix the issue. The next step is to try to identify the issue, to see whether it's app-related or caused by the system itself.

Safe mode will help you diagnose whether apps or Android are the source of a problem. / © ANDROIDPIT

To identify a problematic app, boot into safe mode, by holding down the Power button and then long-pressing Power off. Safe mode disables all apps you've installed so you can assess whether the core system apps are functioning normally. If they are, then one of your installed apps is the problem and you should try systematically uninstalling them one at a time to find the culprit.

If Marshmallow is unstable even in safe mode, then it's an OS problem, not an app problem. You can try clearing the system cache by following the steps outlined in the Battery Drain section above and, if that still hasn't fixed your problem, your last resort is to back up your data and factory reset your phone (also covered above).

Marshmallow charging problems

Despite Marshmallow's new USB charging standards, Android 6.0 charging problems seem pretty common, from devices that drain faster than they charge to phones that simply won't charge at all. Marshmallow is making users earn the battery benefits of its Doze mode and app standby. Google's official solution to a phone that won't charge on Marshmallow is a factory reset, the instructions for this can be found above.

Marshmallow mobile data problems

If your connection to mobile data behaves strangely after the update, try toggling airplane mode on and off, and then doing the same with mobile data in the quick settings. If this still doesn't work, turn your phone off for a minute and then restart it, at which point you'll be asked to re-enter your SIM pin code.

If that still doesn't work you can try removing the SIM card entirely and then reinserting it. If all else fails, contact your carrier to see if there are any known Android Marshmallow problems on your network.

Marshmallow not connecting to PC

If you're having Marshmallow USB connectivity issues, it's most likely because you haven't selected the right option on your phone's software. By default, the device will likely be set to USB charging mode, meaning you won't be able to access your files. 

When you plug your device into your PC over USB, a notification will appear saying Connected for charging. Press on this and you will be presented with four options. The one you're most likely to want is Transferring media files (MTP). This will let you copy files to and from your device via USB. Transferring images (PTP) is your backup option, in the event that MTP is not supported. PTP will make your computer think you've attached a digital camera, allowing for the automated transfer of media files.

Marshmallow 'insufficient storage available' message

If you're being told there's not enough storage space on Marshmallow, it might be related to your SD card. Although Marshmallow now allows SD cards to be formatted as internal memory, there are still apps that cannot be stored on the SD card. Head to Settings > AppsHere, you can press on any app and then tap Storage > Change and select SDCARD. If the SD card option doesn't appear, it's because the app cannot be stored there and must remain on your actual internal storage. 

If this isn't the problem, then you need to make some space on your device's internal memory another way. Clearing app caches is a good place to start. Some devices allow mass cache clearing. Head to Settings > Storage. If you see Cached data here, press it and then press Delete in the dialogue box that appears. If you don't see this option, you will have to go the manual route. Head to Settings > Apps / Application manager and press on any app. Then, select Storage and press Clear cache. You will need to go down your list of apps and clear the cache on as many as you can before you succumb to mind-numbing boredom. 

Once you've cleared out your caches, there will hopefully be considerably more space. If you still need more, you will have to start uninstalling apps and deleting media. Make sure you backup any files you wish to keep for later, though.

    Hi guys, after i upgraded to marshmallow on samsung A7, then my phone is restarting continously and the screen is always showing the blinking 'Samsung' word until the battery went off, cannot even switch on the phone. Does anyone encounter the same issue and know how to fix it?

    • dude i can help you ! try this, go on youtube and write FIXED hanging and rebooting galaxy note4 after marshmallow update

  • The next "trick" works for me:
    - go to Settings
    - go to Network connections> Tethering and Mobile hotspots
    - turn Mobile Hotspot to ON
    - wait 10 sec's and turn Mobile Hotspot to Off
    And I can activate WiFi.

    Sometimes I have to do it twice, but in General it works after the first shot.

  • after upgrading for 6.0 the dial up tone is not working.if i call some one or they call me i cant hear or talk and they cant hear me too.how can i fix this

    • I have a similar problem. I can barely hear them, but they can hear me. It's a little better if i put it on speaker phone. I have called google and they had me restart it in safe mode but that didn't fix it, so they told me to call LG, who told me to set it back to factory default which i did, and it still doesn't work. They want me to mail it in for repair, but i'm not convinced this is a hardware problem but more of a problem with android software.

  • Ive upgraded samsung j5 vodacom to 6.0.1 working well, however facebook cannot be moved to sdcard :( I no longer have enough memory on the phone memory. It cannot use sdcard as internal memory :( Other than that its working well. Cant move my vodacom app or remove the built in apps like deezer, vodacom backup vodcaom appstore. Google hanouts I dont want these apps taking up memory. cant do much now, as I have hardly anything on the pone and its full :( disappointment that facebook you cant move to sdcard or remove, 200meg wasted.

  • My relatively new Samsung J5 is trying to update to Marshmallow, but despite having relatively few apps and an SD card to which I have transferred everything I can transfer, I get the following message:"An additional 1.24GB of available space is required in your device storage to download and install the software update (946.57MB)" This message seems as if I have more than enough. Can anyone explain please?

    • I have j5 and upgraded to 6.0.1 Its best to remove all apps and delete cache data. I managed to get the update on. Working well. Only problem is the facebook app it cant be moved to sdcard. So I have run out of space and cant do much. I have rested to factory defaults, unfortunately the phone doesn't support sdcard as internal memory.

  • my samsung galaxy a5 2016 gets lag while playing games...(i have updated to marshmellow). not like in the lollipop...(games were really playable in lollipop...)what should i do now.....?

    Guys my phone lenovo a7000 a gets stuck while shutting down . The only way it switches off is if the battery drains out or if u remove the battery!!! Pls help me out
    I feel it is a Trojan. I had downloaded an app from a site and I think it came with it

  • I am using Samsung On5. I am facing lot of storage related issues after upgrading to Marshmallow from lollipop. I got insufficeint storage space message and the avaialble space was some 400MB, I deleted few big size apps and made free space of 400MB approx. But, after almost 10 days, now I am again spacing same insufficient storage space without installing back the app. Now again available memory is 400MB. I dont know how the storage space is getting occupied??

  • I have the Note Edge, which I was in LOVE with until after the marshmallow update. Battery drain is ridiculous. Seriously, I just stay tethered to the charger. Apps crash the phone. Plugging in the charger crashes the phone. Phone crashes at 30% battery life or lower. Call me a cynic, but am I the only one who thinks it's NOT coincidental that this update creates major frustration with our current devices JUST IN TIME for the S7 release?

    • Can't be a coincidence. I updated to 6.0.1 on my Edge as well, and I've been having the same issue, even after buying a new battery.
      I ended up updating my Note 4 and I have the issue on both phones now.

    • My phones also get crazy hot (I've measured above 120F on the back of them with a laser thermometer several times). This is probably tied to the battery crash.

    I am an IT Professional who labored through 2 weeks of struggle with my Note 4 after the Marshmallow update. Take it from me...Just do a factory reset now if you are having issues. Nothing else worked. Don't waste your time. I had random reboots and app crashes 5-10 times daily based on phone use including every time I plugged in a charging cable. Yes a factory reset is the biggest pain in rear of all time but it in the end you will get your phone back to 100%. I have had zero issues with any apps or reboots since I did mine...wish I would have done it sooner.

  • Since the Marshmallow update the Facebook and Twitter apps don't refresh and Internet Explorer won't load up pages. Ive tried uninstall and reinstall but problems persist. There doesn't seem to be anywhere to go for a solution. I wish the update could be removed and revert back to the previous. My advice is don't update with the new software as it seems to cause more problems and there is no support . My phone is pretty much useless and will probably need to get an iPhone and ditch the Samsung Android.

  • Test

  • Recently I bought a Marshmallow 6.0 firefly Android.its a good phone but the display keeps timing out every 15 secs even if I set it to 30 mins it still sleep automatically how can I fix or disable this feature permanent? Ty
