Every night before bed, I power down the device and let it charge fully. In the morning I power up the device and remove it from charger.
This morning, the device showed battery 100%, and when I powered up the device, the screen went black but never booted up. It’s completely dead it seems. Will not light up in any way on or off the charger, no LED blinking, no anything! I’ve tried everything every single hard and soft reboot combination of the home/power/ volume buttons, the safe mode boot, everything. The phone will not do ANYTHING, as if the battery is not in there at all… despite showing a fully charged battery while on charger like normal immediately before this happened. It’d like instead of powering on, it killed it. — Matt
Solution: Hi Matt. The first thing that you want to do is check if the problem is outside the phone itself. Try using a different charger and USB cable so you’ll know if any of them is to blame.
You also want to check the charging port visually to see if there’s dirt or defect that’s preventing the phone from charging properly.
If doing the steps above won’t result to anything positive, the only other troubleshooting step that you can do is try different hardware button combinations (which you’ve done already). If the phone remains unresponsive, consider it bricked. Call Samsung or bring it to repair shop.
Problem #2: Verizon Galaxy S6 has no notifications | Galaxy S6 won’t remember sound notification settings
Third phone in a row I’ve gotten from Verizon. Keep having them send me another (refurbished) because the notifications aren’t working. First one wouldn’t send any notifications at all. Then next 2 (this one included) won’t take the sound settings that I set for text messages. It keeps using the default sound that is set. That sucks because that’s the sound for a lot of other crap the phone does and I need the texts to sound differently. Have changed it in settings for the phone/sounds as well as in texting settings and it still won’t take it. Just keeps using default sound. What could be the issue. Factory reset doesn’t help. This is the 3rd phone to do that and they are all coming to me with a factory reset. Frustrated. — Raime
Solution: Hi Raime. If your phone won’t remember the settings even after you wipe it clean via factory reset (and without any third party apps installed), then the problem must be firmware-related. That means that Verizon’s Android code is problematic. The only thing that you can do on your end is to let them know about the situation so their developer team can release a patch to fix the said bug.
I tried to root my phone. I downloaded Flashify and flashed something and now my phone is stuck in a bootloop I believe. My phone is a Verizon unlocked (I bought the phone on eBay and it was factory unlocked). Everytime my phone loads up it shows the Samsung booting screen then sends me to a screen that says “Start up failed, your device didn’t start up succcessfully. Use the Verizon Software Repair Assistant on a computer to repair your device.”
I tried connecting my phone to my PC but it won’t recognize it. I can’t access recovery mode and I’ve tried to go to maintenance mode to factory reset it but it just sends me back to the bootlock screen. — John
Solution: Hi John. Customizing phone software has its risks and the situation you’re in right now sometimes happen. If your phone can’t go past the Samsung logo screen, or simply keeps on rebooting itself, the first thing that you want to do is to try a master reset. Here’s how:
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
If master reset won’t improve the situation, the last thing that can be done on your level is flashing a stock ROM. If this procedure won’t fix the problem, contact the developer of the app you installed so they can provide insight on what can be done (if there is). Otherwise, you’re just one of Android users who find themselves stuck with a bad phone. Contact Samsung or your carrier and see if you have the option to have the phone replaced.
My wife’s S6 is showing some strange behavior that I (systems’ analyst, mobile developer) can’t figure out. The issue is quite simple to describe:
– Internet connectivity works great on wi-fi
– Internet connectivity won’t work at all when you’re in an area without wifi, UNTIL you go into the S6’s settings and turn off the wifi modem. At that point it starts using data, as expected, and connectivity is fine.
So, in a nutshell – it won’t use mobile data UNLESS wifi is turned off – even when you’re in an area with no available wifi – and not connected to any wifi router.
Any suggestions would be much appreciated! — Matt
Solution: Hi Matt. It’s our first time to encounter this issue so this is probably isolated to the phone in question. The first thing that we want you to check is see if the phone’s smart network switch is causing this problem. Try to toggle it between On and Off and observe how Wi-Fi works. To visit Smart Network Switch option, follow these steps:
- From the home screen, tap the Apps icon.
- Tap Settings.
- Tap Wi-Fi.
- Tap MORE.
- Tap Smart network switch.
- Tap On or Off to enable or disable as required.
Should the issue remain regardless of smart network switch status, the next thing that you want to do is boot your S6 in safe mode. This will help you check if one of the third party applications is the cause. Here’s how it’s done:
- Press and hold the Volume Down and Power keys for 20 to 30 seconds.
- Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
- Your phone should continue booting up and you will be prompted to unlock your phone as usual.
- You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
If that won’t fix it, make sure that you factory reset the device.
Hello. I recently had a Galaxy S4 but after shattering the screen switched to an S6. It is an AT&T phone but was used for T-Mobile before I got it and switched it back to AT&T. Before me, it had no problems but since I activated it with my number it’s been giving me a hard time.
The data does not work at all on it. While at AT&T they placed my SIM card into another phone and said that it wasn’t an issue with my network. They tried to change the APN settings but nothing appeared on that screen. Ultimately, they told me there was nothing else they could do.
On Wi-Fi, it also gives me a hard time. It will randomly turn off Wi-Fi even if there’s great connection. I have to turn it back on and sign into my network about 6-8 times in a half hour.
I do not the funds to get something better at the moment. Any help you provide would be greatly appreciated.
Best. — Stephanie
Solution: Hi Stephanie. Both T-Mobile and AT&T support GSM technology so the problem must only be firmware-related. Make sure that you do factory reset to see a difference. Doing so may also fix the Wi-Fi problem you’re experiencing.
Hello. I’m in Pakistan. I have an S6 from Sprint. It was in a good condition no signal problem no other issue. One day suddenly it restarted and stuck on the “Samsung Galaxy S6” logo. I thought it was a firmware issue. I tried many type of Roms — KitKat, Lollipop, official and unofficial flashed through Odin.
Now I’m able to start my phone but there are no signals. If i go to near the tower (very close) then my phone shows the signals. I can make calls and send SMS, etc. But as soon as i go far from the tower there are no signals on my phone. My house is within a kilometer from tower where signal strength is very good for all other mobiles but my S6 can’t catch the signals.
Another issue is that once i power off my phone, it won’t turn on again unless i put it on charging. Its battery gets charged fully then i am able to turn on my mobile. If battery is not charged fully and i try to power on my mobile, it sticks on Samsung logo and vibrates after every 10 seconds.
Please help if there is any solution. Either it is software issue or hardware issue??
I will be very thankful. Regards. — Kaleemullah
Solution: Hi Kaleemullah. There’s no surgical way to identify what the exact problem is but if the usual software troubleshooting like wiping the cache partition, booting in safe mode, and factory reset won’t work, you can safely assume you have a hardware problem at hand. Doing a factory reset will ensure that all default settings, including network ones, are set to their proper values. If the problem is due to a bad firmware, a factory reset should fix it.
There’s also a chance that the problem is due to an incorrect baseband version or modem firmware. Network connectivity is made possible by a built-in modem and this modem requires a special software code, called baseband, in order to work. Normally, baseband is updated everytime a carrier sends an Android update. Baseband version varies by carrier, and sometimes by serial number even among the same phone model. Unfortunately, there’s no way for us to tell you how to determine the correct modem firmware. You must do your own research or find the same phone model from the same carrier so you can have a starting point with regards to the baseband version. This means that if you’re using a custom ROM or firmware on your device at this time, there’s a chance that the current baseband is incorrect or is not compatible with your carrier’s network.
Another likely cause for the no reception problem is a bad network radio. Replacing or even fixing it requires special tools and electronics knowledge but if you’re up to task, try looking for online guides. Keep in mind though a thorough hardware diagnostics is necessary to pinpoint a malfunctioning component. Obviously, doing such a job is requires specialist knowledge about the Galaxy S6. Samsung does not make technical details in fixing their device public so user-initiated repair is out of the question. Make sure that you contact Samsung for a repair or replacement request.
