Problem #1: Galaxy S7 showing “no connection data roaming turned off” error

Been getting “no connection-data roaming turned off” error. So I went to connections, mobile networks, and mobile data, and to my surprise there is no roaming adjustment whatsoever. In mobile networks all that is listed is MOBILE DATA, INTERNATIONAL DATA ROAMING, ACCESS POINTS, AND NETWORK OPERATORS. Mobile data only has two categories, standard data and enhanced 4G LTE services. Yes they both are checked with green. I’ve checked the settings in all of them and they are set to protocols. But there is no way to turn on roaming or if it was on to turn it off.  I cannot turn on or off roaming if there is nothing there. If it is off, will I still be able to text and make calls? — Rick

Solutions: Hi Rick. Carriers often modify generic Android Operating systems to suit their customers’ needs thus settings and options often vary even on the same Galaxy phone model. If there’s no way for you to know whether or not roaming mode is enabled, the best thing that you can do is to contact your carrier. They can then check your account and advise you accordingly.

Problem #2: Company issues Galaxy S7 can’t disable Ultra Power Saving Mode and won’t boot up normally

I have a Galaxy S7, recently issued by the company I work for. I had it fully charged, but I decided to put it into ultra power save mode to reduce battery consumption overnight. I had some issue with this mode not being able to get out of it. Eventually I managed to “get out of UPSM” by using the launcher, but it got from bad to worse.

Now the device is trapped in a limbo between UPSM and the standard mode. Screen is grayed out, there are very few apps responsive, and most won’t even show in the app library. Being a company phone, it’s encrypted and has company administrative policies enforced with MaaS360.

I’ve tried the Power-Volume key hard reset but it doesn’t take me to the menu it should. Just flashes the booting up screen all the time i have the keys pressed. — Jose

Solution: Hi Jose. The usual way to disable Ultra Power Saving Mode (UPSM) is by going to Settings>Battery>Ultra power saving mode>MORE>Disable Ultra power saving mode. If this route is not available for you and you need to do another work around to turn the feature off, that’s already an indicator that your phone may be encountering some conflicts. A situation like this can be due to an installed app, or poor operating system code.

We don’t know the extent of the modifications done by your company’s IT team on the operating system so we really are not in the position to know what’s going on. Your best course of action here is to let your IT guys handle the problem to prevent data loss.

Problem #3: Galaxy S7 videos on YouTube app plays for a second then stop

A couple months back, I started to notice that my videos – on YouTube app, via embedded Facebook videos, and various websites would play for a few seconds and then stop. It would start as if it was slow-mo and then stop altogether. The funny thing is, at random times, the videos would work/play and after a few minutes, it wouldn’t play again.

I’ve searched online hoping others would have this problem and a fix to it. I’ve tried rebooting, and clearing cache and switching to AwesomePlayer in Developer options. Nothing seems to rectify the problem. I’m hoping that Marshmallow solves the problems hence my not taking the phone back to the store (yes, I’m kinda a patient person when it comes to this since I can watch videos on my tablet).

The only thing i haven’t done is a factory reset because I really don’t want to start from scratch and not having it solve the problem. Nonetheless, this problem shouldn’t even exist right? My wife says I have a “lemon” phone. Perhaps you guys can help out as I patiently wait for my 6.0 upgrade. Thanks. — Warren

Solution: Hi Warren. App-related problems on whatever Android device generally follow the same logical troubleshooting — wiping the cache and data,  re-installation, wiping the system cache, and factory reset (in this order). If these four procedures won’t resolve your issue, you can safely assume that the problem is code-related and can only by fixed by concerned parties.

We’ve not heard of this issue being discussed in other forums or reported by members of our community so far so it might be an isolated case as well. Before you do a factory wipe, consider booting your phone in safe mode first so you can observe how it works for some time.

Problem #4: Galaxy S7 crashes after tapping Snapchat notification

Hello. Today I got a snap from a friend, and when I pressed the SnapChat notification, my screen went black. I tried pressing the central button and nothing happened. I thought the device had locked itself, so I also pressed the power button and nothing happened. I continued to press it a few times, and then I pressed it as if I was trying to turn it on, but it was still in black. No light or anything.

I left it alone for a minute and the Samsung sign appeared and finally it turned on.

Then, I got the notification again and tried to open it, but the same thing happened. The phone didn’t respond to anything until after a few minutes, when the Samsung sign appeared again. But then, it got stuck in the process of turning on, and I was freaking out.

Eventually it turned on and as soon as I unlocked it I uninstalled Snapchat.

The same restarting thing happened and I turned my mobile data and Wi-Fi of.

It hasn’t happened again since that, but I’d like to know if it’s Snapchat’s fault or if the problem comes from the phone.

I appreciate your help because I am in the verge of tears right now.

Thanks. — Victoria

Solution: Hi Victoria. SnapChat crashing on launch is a known issue for quite some time now, it being reported in numerous Android forums. If the rest of your apps appear to work fine and only Snapchat is giving the headache, that’s an obvious indication that Snapchat is to blame.

Snapchat’s own support page would recommend that you uninstall the app to force your device to install the latest update later on. If re-installation won’t work though, the next suggested troubleshooting step is to use Snapchat on cellular data or Wi-Fi to see if the bug is triggered by a particular connection type.

Some users of this app would recommend the generic solution of clearing the app’s cache and data but since you’ve already tried re-installation in the past, we doubt if doing their suggestion will help. We recommend instead that you fill out a form in Snapchat’s support page so you can ask assistance directly from their developer team.

Problem #5: Galaxy S7 frequently drops calls due to poor signal | Fixing poor signal issue on the Galaxy S7

Hi DroidGuy. My mom’s Galaxy S7 just randomly refused to make or receive calls, and frequently does the same with texts. After much jiggering with her phone and many internet searches, I couldn’t find a solution. However, when I stepped into the front yard, I was able to use her cell to call and text mine. I noted that the signal strength had kicked up when I was outside, and figured that was the problem.

Back in the house, sure enough, her signal strength was fluctuating between one bar and nil. Her cell has NEVER had an issue with signal in her home. She hasn’t downloaded any new apps, done any sort of construction or repairs to the house (I know some materials and such are more difficult for a signal to go through), and she’s been with the same carrier and had the same cell for about a year. I don’t know if the system recently had a software update that mucking about with stuff thanks to some jacked coding or what.

I really hope you can help! — Lee

Solution: Hi Lee. A fluctuating signal when a device is inside a structure can be caused by a few factors, some of them beyond your control. These factors include signal interference, distance from a cell tower, or software glitch.

On a user’s level, one must ensure that it’s not the device that’s causing this trouble by doing some basic software troubleshooting like wiping the system cache and doing a factory reset. For reference, here are steps on how to boot in recovery mode so you can do these two solutions.

Wiping the cache partition

Making sure that the device’s system cache is fresh can be an easy fix for this problem. Here’s how it’s done:

  • Turn off your Samsung Galaxy S7 Edge.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Wipe the phone via factory reset

If the issue remains after the system cache has been deleted, the next logical step is to restore your phone’s settings to default. This can easily be done by doing a factory reset. The only downside to this procedure is the hassle of creating a backup copy of important files like photos, videos, contacts, etc. Make sure that you don’t forget to back everything up before you proceed. The exact steps to do a factory reset are almost identical to wiping the cache partition, and the only difference is by selecting “Yes — delete all user data” option instead of wiping the cache.

Now, if these two procedures will not change anything, the reason for the problem may either be obstruction, which results to interference, or something on the network side.

Every object between a cell tower and your device can be a source of signal interference. Thick walls, trees, mountains, buildings, wire mesh, are some of the common obstructions in our everyday digital world. The more obstructions a signal has to go through before reaching a device, the more likely the problem like yours materializes.

Of course, the distance a signal has to travel before reaching a device also matters. Carriers plan the location of their towers to provide maximum coverage for its customers. In a perfect world, your device is supposed to connect to the closest tower automatically but sometimes this does not happen. Changes in network infrastructure and outages can also a role. Whatever the true situation of the network is, it’s usually beyond any average user. The best course of action that you can do is to let your carrier know about the problem so they can help.

And speaking of help, your carrier may be able to magnify the signal inside your mother’s house with the help of a signal booster, also known as a cell phone repeater. Basically, an outside antenna can be installed outside your mom’s house so it can forward the weak signal to an amplifier inside. An amplified signal is then sent to an indoor antenna which broadcast the carrier’s service. The process can be reversed if your carrier determines that there’s a weak signal coming from your mom’s house to the cell tower.

Not all carriers support signal repeaters though so make sure that you mom work with her wireless provider in order to get one installed at her place. Although one can install a signal booster independently, more advanced knowledge is necessary to make it to work effectively. We highly suggest that you let her carrier install the device instead to ensure that it works.
