Below are specific topics we’re bringing for you today:

Problem 1: iPhone 7 has no speaker on the bottom left side

I have the iPhone 7 plus and it has a total of 3 speakers I believe. one where you put near your ear when making a phone call, one on the right side of the charging port, and one on the left side of the charging port. The speaker to the left of the charging port does not work at all. When you play music you could only hear the music coming out of the ear speaker, and the right side of the charging port.        — Andres

Solution: Hi Andres. Both iPhone 7 and iPhone 7 plus don’t have three speakers. They only sport two, one in the earpiece and the other at the bottom right side. The bottom left side holds the barometric vent. It’s mainly not related to audio function at all as it’s a sensor to measure altitude. So, there’s no need to panic and simply enjoy your iPhone 7.

Problem 2: iPhone 7 can’t hear caller, speaker making echoes

Getting frustrated with iPhone 7 plus because I’m having trouble making calls and on speaker mode:

 

  • when ever i make call, sometimes it is working fine. But for some contact i always face same trouble — no ringing, no voice. If that person pick up the phone I still didn’t get his voice. But if that person didn’t pick the phone or phone is switch off, then i hear from phone that phone is off or the party is not receiving the phone. I really don’t understand what is wrong with this phone. I just got this phone on 2nd Jan 17.
  • whenever i make calls and put call on speaker mode, i always hear noises from my phone like if i say hello it is repeating same like ‘hello hello hello.’ If i say not well the also not well not well not well..

 

Please help me. I’m really getting frustrated every second. Don’t make me feel i made a very big mistake by buying this iPhone. — Pawan

Solution: Hi Pawan. We think both issues are related and may be caused by one and the same thing. Let’s see what you can do in this case.

Force close Phone app

To kick off your troubleshooting, you first want to ensure that the native Phone app is working fine. To do that, you want to restart the phone. Afterwards, you want to Force close the Phone app. Here’s how:

  1. Double-click the Home button to see your most recently used apps.
  2. Swipe right or left to find the app that you want to close (Phone).
  3. Swipe up on the app’s preview to close the app.

After force closing the app, try to see if calls will begin working normally. If you’ll encounter the same problem, proceed to the next step.

Try another similar app

If calls continue to be problematic, look for a similar app from the App Store and use it to make your calls.

Install app and iOS updates

If the issue persists even when using a second phone app, make sure that your phone runs the latest iOS version. You also want to make sure that all your apps are updated.  To do that, follow these steps:

  1. Open the App Store and tap Updates.
  2. If updates are available, tap Update All.
  3. If asked, enter your Apple ID password.

Test your device’s microphone

We think there’s a problem with your phone’s microphone. This may be the reason for the second issue. To check if there’s a microphone problem with your device, you can do the following:

  1. Open Voice Memos app.
  2. Tap the Record icon.
  3. Try to record your voice for up to 30 seconds.
  4. Listen to your recorded memo.

If there’s no problem with the microphone, you should be able to hear yourself clearly. If it’s otherwise, then you have a bad microphone and you need to have the phone repaired or replaced.

Restore all settings to factory defaults (factory reset)

If you’ll hear your recorded voice clearly, then the most likely cause of your problem is an operating system glitch. To fix it, you must do a factory reset or a full restore. Here’s how:

  1. Create a backup of your files. You can do that in a number of ways but the fastest and most effective way is by using iTunes in your PC or Mac. If you don’t want to create a back at all, you can simply erase everything on the phone by following the steps in this link.
  2. Connect your iPhone to your computer with the cable that came with your phone.
  3. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  4. Select your iPhone once iTunes asks you for the specific device.
  5. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore [device]).
  6. Confirm by clicking on Restore button.
  7. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  8. After this factory reset, all software settings should be restored to their defaults.

Problem 3: Only iPhone 7 bottom right speaker works when in landscape position

My iPhone 7 speakers are messed up. Only about a week after I got it, I was watching a video when my bottom right speaker stopped working. My left speaker never worked, so I wasn’t worried. But now whenever I listen to music, only my left ear works.

Also, when my phone is vertical, only the top speaker works. Then when my phone is on its side, it only works on the bottom right speaker. Please help. — Callie

Solution: Hi Callie. As mentioned above, an iPhone 7 has two speakers to allow it give a stereo effect. This stereo effect is automatically enabled if the phone is on landscape position (on its side). You can however override this automatic feature to direct sound to only one speaker (Mono Audio). Your observation is normal though as music only plays via the bottom right speaker when your phone is on landscape mode. When in Portrait mode, music plays via the top speaker.

For reference, here are the steps on how to direct sound to one speaker only:

  1. Open Settings.
  2. Tap General.
  3. Tap Accessibility.
  4. Scroll down to the audio volume balance slider and move it fully to the left or right.
  5. If you want to use Mono Audio, simply enable it. It’s located above slider.

Hi. I just purchased an iPhone 7 two weeks ago from  metroPCS and my iPhone was working perfectly until about 3 days ago when the new update popped in my phone. I chose to start the update and immediately my phone started acting crazy. It was on about 30% battery charge but was plugged into the charger. Once the update started the phone went black and then the white apple screen came on but it didn’t have the loading bar and front that point on the phone. wouldn’t stop coming on and off.

It would constantly show the Apple screen, then the dead battery screen non-stop. Now the phone won’t charge nor turn on. The only thing that happens when you put it on the charger or try to restore is the Apple screen. Then it will cut off and show the dead battery charging screen but it won’t charge.

Please tell me what i should do. I really need my phone and it’s already been 3 days and metroPCS telling me to bring it back to Apple. — Chynasti

Solution: Hi Chynasti. An issue like this can be caused by bad software, problematic app, or malfunctioning hardware. Unfortunately, there’s no easy way to tell which is which. The only effective method in bringing back the normalcy of a rebooting iPhone is the restore option. If your phone won’t even load properly to allow you perform the steps to restore it, then your best option is bring it back to Apple. There’s no software trick or hardware button combination that can help you in this case.

Problem 5: Can’t upload photos from iPhone 7+ to Macbook

I just bought an iPhone 7+ and Macbook. I am having trouble with uploading pictures. I have tried all suggestions. I use to plug my old phone in and iPhoto would open. Now on the new computer, i only have image capture and can only copy photos, not down load. Do I need an adapter now? Is this an issue you have a trick for me to try. I press trust on the iphone but it keeps saying iphone needs to be unlocked even though it is. — Rubyslippars

Solution: Hi Rubyslippars. Importing photos from your iPhone 7 to your Mac requires iTunes. Make sure that you run the latest iTunes version in your computer. Once you’ve taken care of that, you should then connect your iPhone 7 to your Mac via a USB cable. After that, you want unlock your phone by putting in your passcode (if applicable).

If prompted, make sure to designate your Mac a trusted computer. Once you’ve tapped Trust, make sure that you also tap Continue in iTunes.

Since your computer seems to ignore your Trust command in your phone, these are the steps that you can do next:

  1. Disconnect and reconnect your iPhone from your computer.
  2. Restart your iPhone and your Mac.
  3. Reset the Trust settings in your iPhone by going under Settings > General > Reset > Reset Location & Privacy.

You can also go under Settings > General > Reset and tap Reset Network Settings to reset all wireless settings like wifi networks and passwords, APN, VPN, and cellular settings.

Problem 6: iPhone 7 draining battery fast

I have tried everything your site suggests and still my new iPhone 7, which I received as a Christmas gift, will not hold the charge no matter what I do. I’ve changed outlets, cleaned the connection, checked for any sort of moisture, uninstalled a game that I thought may have been draining the power, re-set the phone by holding the volume button down and the on/off button. so now I am at my end. It has always held a charge until recently but nothing has changed in my “world” to cause the phone to not hold its charge. In the AM, it will be charged 100% then after less than 2 hours, it is down to 62% and all I did was read my e-mails and my daily prayer. Please help me with this so I don’t have to make a trip to the Apple Store and wait hours for help. Thank you. — Suzway

Solution: Hi Suzway. Battery drain issue like yours can be a result of a number of things such as software, content (apps), usage habits, or bad hardware. To know which of these items is the real cause, you want to establish a baseline first. This is done by restoring all settings to their factory defaults. Be sure to back your photos, videos, etc. to avoid losing them. Then follow these steps:

  1. Sign out of your iCloud account (if applicable).
  2. Go to Settings.
  3. Tap General.
  4. Tap Reset.
  5. Tap Erase All Content and Settings.

Now that your phone is running only its stock and official firmware (we assume your device is not jailbroken), let it be that way for 24 hours and observe it. Don’t install any apps to it. This way, you’ll know if the battery drains at the same rate or not. We expect that the issue will not occur while your phone is in this state but if it does, then there may be a problem with the battery or some hardware. In that case, you’ll need to send it back to Apple so it can be checked.

If the phone appears not to show battery drain issue after a factory reset, that’s the time that you want to install apps one by one. We don’t know apps you have but if the issue returns after installing all your apps again, you can bet one of them is to blame. In that case, you’ll want to uninstall app individually, making sure to check if the issue happens after each uninstall. This is a tedious process but it’s the only effective way to pinpoint the culprit.

Problem 7: iPhone 7 video sound is low

I’m having trouble with the sound for my iPhone 7. It’s new, only two months in use. I felt that speaker sound is not that much loud and I’m not sure if this is normal. I took two videos yesterday and sound was fading; its sounded really loud at a glance, and all of a sudden it went very low. This was the first time I took a video and this happens. There is a way to check this mine has IOS 10.3.1 . I Have trouble understanding why it only sounds at the right side the left acts as the voice mic when you are in a call? — Eddie

Solution: Hi Eddie. There are two possibilities for your problem here. One is that camera app you’re using is buggy and does not capture audio very well when you’re taking videos. If you’re using the native Apple camera app, try to see if a phone restart and force booting will help. To force boot an app, you must do the following:

  1. Double-click the Home button to see your most recently used apps.
  2. Swipe right or left to find the app that you want to close (Phone).
  3. Swipe up on the app’s preview to close the app.

If you happen to be using a non-Apple camera app when recording videos, try to force close it first. If the issue persists, try using a similar app or the native camera app.

A second possible reason for your problem may be a microphone malfunction. Your iPhone 7 has 4 microphones — two of them are on the side of Lightning port, the other one is on the back between the True Tone flash and iSight camera, and another one inside the earpiece. To see if your phone has trouble capturing sound, refer to the steps we provide for Pawan above on how to test the microphone. If the phone has a microphone problem, contact Apple and have the phone replaced.

Problem 8: iPhone 7 deletes texts randomly, won’t send MMS

Hi. I have contacted both Apple and Verizon and they haven’t been able to conclude on the problem with me and my sister’s iPhone 7. Nothing has happened to either phone, other than running out of data last month, and having to buy more (it restored last night to the next month so that shouldn’t have anything to do with it.) First, my sister’s iPhone 7 randomly deleted all her texts (she did not sign out of Apple ID or anything) and she wasn’t able to send or receive texts (calls worked fine). Then, I was also effected as my phone would no longer receive or send pictures when sent by SMS, iMessage, on or off wifi and i have no idea why. I have reset network settings, reset iPhone by holding down power and volume button and even called Verizon to see if there was a block on any form of messaging and there was not. I found it strange that both of our phones were acting this way. Why is this happening/what can I do to fix it? It’s not internal or the iPhone itself because it randomly happened to both of us (we are on same Verizon and data plan.) If you could help that would be amazing!! — Haley

Solution: Hi Haley. Is there someone else other than both of you that may be able to access your account settings or inboxes remotely? If you’re not paying for your bills, then there may be a way for someone that handles your account to go into your Verizon account or device and change some things. Other than this, we’re just as clueless as Apple and Verizon. Since this has something to do with your network services, we would recommend that you continue to work with Verizon until the issue has been resolved.

Problem 9: iPhone 7+ Touch ID does not recognize fingerprint

I recently took my iPhone 7+ to our service carrier where we purchased the phone from. My issue was a problem with the volume. When I received a phone call, almost none. The technician took my phone for a diagnostic and after two hours he said the phone should need to be sent to Apple. I was leaving on a cruise for a week and said I would need to wait until I returned. After 1 day in the cruise I noticed that my sign in code area went from 4 to 6 spots and I had only had a 4 digit sign in. Now my phone won’t open. I have touch sign in ability but after turning my phone off, this won’t work until I put in my code. Help. — Donnaroof2

Solution: Hi Donnaroof2. There are only two possibilities for Apple’s Touch ID in the iPhone 7 and 7+ — it either works or not. It’s definitely not a perfect system so you want to ensure that you minimize factors that might hinder its ability to recognize your finger properly. Below are some of the things that you can try:

  1. Make sure that your finger is not wet or sweaty when authenticating. Keep it as dry as possible before placing it over the Touch ID sensor.
  2. The Touch ID sensor is composed of a capacitive ring around it and when it senses your finger, it captures an image of your finger. Make sure that your finger touches the capacitive ring around the sensor to increase the likelihood of the sensor capturing an image of your finger.
  3. Don’t take your finger too quickly off the sensor.
  4. Refrain from moving your finger around when authentication is in progress.
  5. If you put your phone in a case, make sure that it does not prevent your finger from touching the capacitive ring properly.
  6. Try to delete the current fingerprint and re-reregister it. Be sure not to move your finger when trying to do a re-registration or scanning. Also, make sure that the every edge of that finger is scanned properly.

Problem 10: iPhone 7 screen stays black, won’t turn on

The screen on my iphone 7 keeps going black. It’s still receiving texts- I can feel vibrate and it rings for phone calls. I can feel functions happening. I used the troubleshooting on my iPad to turn it back on twice- holing the volume and home screen buttons for a bit and it worked but then went out again in about 15 min or so each time. The phone is fully charged. I had to take the cover I’ve had on it since I got it a couple months ago to even make that work. However, this third time in a day, it will not work. — Melissa

Solution: Hi Melissa. We don’t know the full history of your phone but most display-related problems are caused by bad hardware. If you ever dropped your phone or had it physically impacted before this problem started occurring, you should stop looking for answers. What you want to do is to contact Apple so the screen or the phone is replaced. We’re sorry but there’s no software tweak that you can do to fix a broken screen.

If your phone was never dropped or exposed to water or temperature extremes (heat or cold), then there may be an unknown software or app glitch causing it. Kindly visit this post to see if there’s something that you can follow to fix it on your end.
