Problem #1: Galaxy Note 4 can’t use LTE in Sprint network

Hi. I came to ask for help for my mom’s phone. She has a Samsung Note 4 and it works perfectly fine but there is no LTE or cellular data. You can call/text, perfectly fine. However the internet only works when the device is connected to wi-fi.

I have contacted Sprint, which is our carrier, after their attempt to resolve it still doesn’t work. I have tried to update it and reset all setting… the LTE data still does not work. Also, it shows ‘NO SIM’ on the top of the screen but there is a SIM card placed in the back. The phone shows the ‘3G’ sign loading all the time. Please try to help. My mom bought this phone in December of 2014, so I know that means it’s past its 1-year warranty.

Thank you. — Iluminada

Solution: Hi Iluminada. There are a number of things to consider to try to fix your issue. Below are factors that you should work on:

Check if LTE is working in your area

The first thing that you need to check here is to find out if there’s LTE coverage in your area. This can be done by calling your carrier to get a confirmation from them. Perhaps the main reason is that there’s only a 3G coverage where you live. You did not indicate in your problem description whether or not this device was able to use LTE in this same area before so you must check it first. Not all areas in the United States are LTE covered so it’s worth checking. It’s also possible that there may be some issues with the existing LTE service from Sprint in your area so you must really talk to Sprint again.

Ensure that the SIM card is activated and working

CDMA phones, like the ones from Sprint (which uses CDMA technology), don’t generally need SIM cards to work. That changed with the arrival of LTE technology, which is basically an enhanced GSM technology. LTE standard needs a SIM card to work so CDMA networks such as Verizon and Sprint equip their phones with SIM card slots so they can use LTE. Unlike GSM phones though, Sprint and Verizon still authenticate subscriber information on their networks via CDMA, meaning via a special program code in the phone itself. That said, you must ensure that the SIM card for LTE is working first. That the phone is showing “No SIM” error on the status bar may be a sign that the SIM card may not be activated, or defective.

Have the hardware checked

If LTE service in your area is working and the SIM card is registered to Sprint network, then the reason for the “No SIM” error may be due to a bad SIM card slot. This means that you want to have the phone checked. If it’s no longer under a replacement warranty, we still recommend that you let Sprint do the repair to avoid complicating things.

Problem #2: Galaxy Note 4 screen turns blue | Opening camera app turns Galaxy Note 4 screen black

Good day sir. I have a problem with my Samsung Galaxy N4. first the phone started losing sound. the sound was working on and off then finally it stops working totally. After the sound problem, i started experiencing blue screen. Suddenly, my phone will freeze and screen becomes blue. Than i started to notice that the camera failed. if i open the camera the screen turn black. The phone will also reboot several times.

I have done factory reset and hard reset to no avail. Each time i do factory reset or hard reset, the phone will work normally for about 30 minutes then crashes again. I took this phone to the dealer and he change the microphone and speaker but no solution. He said the motherboard is dead but i believe he could not fix it so he concluded that way. I still want to keep this phone. How can i rescue this phone? Any soft or hardware tips? — Uncle_vick

Solution: Hi Uncle_vick. If you want to extend the life of your phone, we say you start by trusting technicians who check the condition of the hardware. Based on your problem description, the multiple failures of different functions suggest a failing motherboard. This the reason why even a factory reset did not improve the situation. Software solutions can’t obviously fix hardware problems so we say you bring the phone back to the repair shop so a technician can check if something can be done to make this phone stable again.

Our blog does not provide hardware troubleshooting and solutions so if you are intent on fixing the issue yourself, find other websites that can provide you with do-it-yourself guides.

Problem #3: Galaxy Note 4 turns off is battery level reaches 70%

Whenever my battery is below or around 70% and I use the camera, it immediately shuts down the phone. I can power back up if attached to a charger or remove the battery. It will also immediately shut down whenever it gets to around the 40-50% battery range without using any apps. I recently got it back from Samsung repair because it wouldn’t fully reboot, it just kept in a cycle of trying to start up. They replaced pretty close to everything in the phone according to the repair ticket. — Marci

Solution: Hi Marci. If this phone just came from a Samsung service center, you might as well return it back to them so they can check it again. We know that’s a lot of hassle but it’s the most effective way towards resolution. For all we know, there may be a hardware issue that remains unaddressed at this time.

If you want to see if you can do something on your end before sending it back, try calibrating the battery first. Doing so will help train the operating system to read battery levels correctly. Here’s how it’s done:

  • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  • Turn the phone on again and let it turn itself off.
  • Charge the phone without turning it back on.
  • Wait until the battery says it fully charged to 100%
  • Unplug the charger and turn the phone on.
  • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  • Unplug the charger the turn the phone on again.
  • Use the phone until you drain the battery down to 0.
  • Repeat the cycle once.

The other thing that you can do is to restore all software settings back to default. This will force the phone to revert all software settings to its known, working state. If an operating system glitch or an unknown bug is to blame, factory reset should eliminate them. Make sure that you observe how the phone works without installing any app to see any difference. Below are the steps on how to do a master reset:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

If these two procedures won’t make any difference, you can try to see if using a new battery will help. If another battery won’t improve the situation either, send the phone back to Samsung.

Problem #4: Cannot save photos when using Google Search app on Galaxy Note 4

Hi! I came across your gadget help pages online and your email address hoping you can assist. I have an AT&T Samsung Note 4, just got it in May of this year. Everything has been working great until a few months ago. On both my Google app and Internet Browser, I have NOT been able to touch, hold and save any images. I consider myself to be pretty tech-savvy, went through all my settings (maybe my fingers slid something on/off?) -and I cannot find anything in settings that would ultimately affect the phone’s ability to touch and save an image.

I’ve searched online for troubleshooting help, and the only help offered for saving an image is the general instructions “touch, hold, save” – right.

My phone’s issues are deeper than just not knowing how to hold and press your finger on an image, and wait for the options to appear.

Please help! I really don’t want to go into my AT&T store. I think they’re all I-phone trotting morons and know nothing of the android world of wonders! hahah

Phone Info:


Model number: SAMSUNG-SM-N910A

Android Version: 5.0.1

I don’t know what other information you need. Please help!! — Sarah

Solution: Hi Sarah. Not all apps have the same functionalities so if you can’t do a certain thing from one, try another similar app to do the same job. In other words, if you can’t save a photo from, say a Google Search app, you can try using a Google Chrome browser instead. In Google Search app, which is different from Google Chrome, for instance you will not get any options when you “touch and hold” a certain photo you just searched. On the contrary, doing a “touch and hold” on a searched photo in Google Chrome app will give you multiple options including one to let you save it.

Problem #5: Verizon Galaxy Note 4 not working with Bharti Airtel in India

Hi Team. I got to know this mail ID through online portal and please help me out with the issue. I have with my Verizon Note 4 device which I bought from USA. I have bought this mobile phone on device-now online portal and they have claimed that this phone is completely unlocked.

Based on their confirmation I have bought Samsung Galaxy Note 4 from Verizon network to use the same in India with Bharti Airtel network in Chennai, India.

It’s been long time and I have tried all the normal settings to GSM or GLOBAL and APN and other few well know troubleshooting steps but till now I do not see any signal in my mobile and I could not use it till date.

I kindly request you to give me any positive solution to fix this issue and to use my phone please…Thank You!

Eagerly awaiting for your reply. Regards. — Dhinesh

Solution: Hi Dhinesh. First we want to emphasize the importance of knowing the differences of the commonly used mobile technology in the world — CDMA and GSM. These two technologies are incompatible with each other. GSM networks use a SIM card to store subscriber information, while CDMA phones keep these same information in the device itself. CDMA devices need to be reprogrammed if subscriber-related changes are to be made, or if a user decides to use it to another network. GSM devices, on the other hand, only need a simpler network unlock procedure and a new SIM in order to run to another GSM network. For example, in the United States, T-Mobile users can easily connect to AT&T network or vice versa as long as their phones have been network unlocked and they have a activated SIM card. This is not true for Sprint or Verizon users though as a user must call their network first in order to reprogram their device if they wish to cross to another CDMA network.

If you think it’s such a hassle to use a CDMA device to another CDMA network, the same can be said when using a CDMA phone to a GSM network. It’s also possible that a CDMA phone like a Verizon Note 4 won’t be able to use 2G and 3G in a GSM network. Voice and text messaging works only works on 2G and 3G so if your phone don’t pick these networks up, that means that that device won’t be of much use.

CDMA phones have available an SIM card slot but that does not mean that they can use a SIM card like what a regular GSM phone does. The SIM card slot is there in order to allow the phone to use LTE technology only. As LTE does not allow voice calls and SMS, there’s literally nothing that you can do about it.

A quick Google search says that Bharti Airtel network uses GSM mobile technology. This means that even if your Verizon Note 4 has been network unlocked (generally, Verizon phones are now network unlocked as soon as you buy them), you will be unable to use the phone for voice calls and text messaging. You either have to request a phone replacement that can work with a GSM network, or simply accept the fact that the Note 4 is basically useless in your location. If you have a CDMA network in your area, try to contact them to see if they can accept your Note 4 in their network.

Problem #6: Power adapter to use for Galaxy Note 4 in Czech Republic

Hello. I was reading your website and want to take you up on your offer of asking for help. Thank You!

I have a Samsung Note 4 and when I bought it, here in the Cayman Islands, the adapter that came with what looks like an European plug. Then the clerk sold me an adapter so that I can plug it in. (In the Cayman Islands, we have the same plugs as in the US and Canada).

I had a Samsung Note 4 in Canada and this plug is totally different.

My issue is, I am travelling to the Czech Republic soon and their electricity is 240. Excuse me but I’m not totally sure what I am talking about! (smile)

I was wondering, if I can just buy a “North American style” plug for this phone and then – buy an adapter for the Czech Republic?

Or, if you can tell by the photos I have attached, what type of adapter should I try and find?

Thank You for any help you can offer me! Sincerely. — Bronwen

Solution: HI Bronwen. Generally, the residential voltage in European countries ranges from 220-240 V so if you’re still using the original Samsung charger, you should be okay. That charger can operate between 110 – 240 V so all you need is just the right adopter, which you may want to get when you arrive in Czech Republic. As there are many different types of power outlets around the world (and we don’t know which one is applicable in the Czech Republic), we recommend that you buy the applicable adapter once you’re there. Checking on the photos of adapters you currently have, we think everything’s covered when you’re in Czech Republic.
