Accurate cell signal strength for the iPhone

Is there a menu somewhere in the menu hierarchy that displays the current signal strength the pone is experiencing, in, say dbm? A typical number would be in the -80 to -90 range...

You can also make it permanently display the decibels. While in field test mode hold down the power button until you see the slide to power off... then hold the home button down until it goes back to the home screen... The decibels will now be displayed where the signal bars used to be. You can switch back and forth between the two just by tapping the signal bar area.

  • Does the Note 4 have better signal strength than the Note 3?

    I have a note 3 that continually drops calls and bounces from 4 bars to 1 bar over the course of time with the phone being stationary.  I believe my problems started with the last software update (as documented in numerous forums) but both Verizon and Samsung give no credibility to problems raised on internet forums.  The people on these forums apparently "lack technical expertise" was my take on their explanation. 
    So far they, Verizon, is following exactly the same course of action to try to correct my issues as other folks have stated they tried with tech support.  Replacement of the SIM card did nothing.  Software reflash is next followed by a factory reset with no additional apps allowed to download to the phone. 
    I have not looked at a Note 4 nor do I know anyone that has one so I am reaching out for information.  What is the Note 4 running for software and if you owned a Note 3 previously did you experience signal strength issues where you felt you shouldn't have?  If you had, or have, weak signal strength were you able to compare it to another android phone on the same carrier to see if the problem was specific to you phone?
    I understand the bars are not the best indication of signal strength but they are a quick indication.  Under the mobile networks I usually have -100+ dBm and 30 +asu.  If it is a software caused problem neither Verizon or Samsung knows anything about it which is good news because they should be able to correct it.  I have my doubts the people on the forums are the crackpots they make them out to be.  I suggested they are people like me who are desperate for help with a problem Verizon gave up on. 
    If the Note 4 is better I know what to ask for when they hit the end of the road with me.  That will happen software and reset wise in the next week then I am off to "getting someone else's problem phone" sent to me for a swap.  Last time they tried this the junk phone they sent didn't even recognize the sim card! 
    Thanks for any facts you can provide about your experience with the Note 3 and Note 4 as related to signal strength in both areas with strong and marginal service.

    I have an iPhone 6 on Sprint for work and it stinks, I don't like the service or the phone.  Had an iPhone 5s prior and although I didn't care for it it was still better than the 6.
    I had a software reflash done at Best Buy and a factory reset at Wireless world.  Reflash went smooth but I should have done the factory reset myself or had Best Buy do it.  It will take me days to get the phone back to where I had it.  Kies software from Samsung does backup the phone but you lose all the changes you have made to the Home screens and some other apps need attention to get them functional. 
    Signal strength remains the same but need to use it for a few days to know if it still drops calls and breaks up.  If it does next on the list is running in safe mode for a few days to see if an app is causing it.  If the problem still persists I have the choice of replacing it with insurance, money out of my pocket.  Sending it to Samsung for testing and repair (if necessary), or having Verizon send a replacement refurbished phone.  Probably will go with the refurbished phone and hang on to mine for a few days as well.  If the refurb isn't any better I will return it and then send mine to Samsung. 
    According to Wireless World the insurance company will pay me for my phone if I trade it in before a year is up.  May get up to 50% of full retail.  Not sure what to trade it in for if I go that route.

  • 1/8" audio line-in cable for the iPhone?

    I just bought a Kaossilator (and it's the best thing ever--search for it on YouTube). Long story short: I need to be able to record on the iPhone through the 1/8" jack--does anyone know of a cable that (like the iPhone headphones) will allow me to bring an audio signal into the iPhone?
    I assume I need a proprietary cable (in fact, I've already tried a standard 1/8" to 1/8" stereo cable, and it didn't work). However, I'm not sure where I'd find such a thing, and I thought maybe your gurus would know.
    I have an original iPhone.
    Thanks for your help!

    That's actually the cable I've already tried--and it didn't work. Typical balanced 1/8" cables only seem to send an audio signal OUT from the iPhone.
    I think I need a cable with the same connections/(wiring?) as the headphones that incorporate microphones--how they're different, I'm not sure, but they must be.
    Anyone know what makes the iPhone headphone cable special? Or where I can find that sort of cable with a female 1/8" jack instead of earbuds?
    Thanks for your help, everybody!

  • Why is the IOS 8 update not available for the Iphone 4?

    Why is the IOS 8 update not available for the Iphone 4? Will it ever be available? I cannont afford a new Iphone at this time so why am i being penalized for not having a new Iphone. Very upset

    Well of course they would, but that's not why iPhone 4 can't have iOS8.  It is simply the fact iPhone 4 can't support the features of iOS8.  Le'ts be realistic in recognizing iPhone 4 is now over 4 years old.  In cell phone land, that is ancient........

  • Sirius and XM for the iPhone

    Hey all, just wanted to give the heads up on Starplayr for the iphone. If you have sirius or xm this shoul dbe in the app store soon. I am a beta tester with both services and it is fantastic app for the iphone, lyrics, art work, just great. So be patient, i've seen people ask if these services were coming to the iphone for a period of time.

    I read that "Sirius XM is planning to launch an iPhone application by June in a move to expand its market, the satellite service provider said Thursday during an analyst conference call."
    http://news.cnet.com/sirius-xm-tuning-in-to-iphone-application/?tag=mncol
    I am a Sirius subscriber with a lifetime subscription (so I don't have to pay for online streaming) and am buying the next iPhone this summer.
    This may sound stupid, but would I be able to listen to sirius stream while driving in car or do you have to be in a Wi Fi hot spot?
    I'm new to using cell phone for internet... Are there various packages that deal with this? Thanks : )

  • IM+Skype for the iphone

    Alright I have a question about the skype for iphone service. I thought I understood but aparently not the case. So first to use it i must pay $25 for a lifetime purchase or a $4.95 a month fee. Alright so it's free to call someone's skype account from it and it only costs a small fee to call a real phone? I had thought prevously that it also uses your air time minutes. However, the skype website says it is for the ipod touch as well. How can it use airtime charges then? or is it only free when hooked up to wifi?

    what i can gather though is it calls you back. My girlfriend is currently in london so i am trying to find the best way to call her. All I have is my cell phone and a pc, i'm in a dorm room. Otherwise i would just use a calling card and pay $0.03 per minute. Heard about skype for the iphone, I use skype to talk with her over the pc. just would be nice to talk anywhere.

  • Can anyone tell me the mAh needed for the iPhone 5?

    I am looking to purchase an Emergency USB cell phone charger and want to make sure there is enough power (but not too much) in the device.  I can't seem to find the answer yet???  I purchased one and it did not say anything about how much power it has but it did say it will work with the iPhone 5.  I should know better than to believe something that an after-market manufacturer posted but I was hopeful.  It worked from 0 battery to 12% and then said "not compatible with this phone" (or something like that). 
    I am not knowledgeable about power, iPhones, horse training and many other things , but I hope to learn on this forum since I just bought my first iPhone and am trying to figure all this out.  I need to be able to carry a power source with me when I am away from electrical outlets and such.
    Any input is mucho appreciatedo!   Thanks!

    Thanks Peter, but what I am looking for is something like http://www.amazon.com/Portable-Battery-Powered-Emergency-Flashlight/dp/B003ZUPDR 2.  I would like an external pack that takes batteries and can be quickly used to recharge my iPhone 5.  There are a lot of them like this one on the market but I need to figure out the power specifics needed for the iPhone 5.  I will also be buying these for gifts for about 45 people for an event this summer so I am doing the testing with my iPhone and hoping to find something like this.

  • Can i use my husbands upgrade for the iphone 6 promotion

    My line is technically not eligible for upgrade, but my husbands line is (we are on a family plan with my mom). Last time I upgraded, they let me use my husbands upgrade since his was available. Can I do this for the iphone 6 promotion or will they not allow it?

    Can I transfer upgrade eligibility from one line to another?
    If you have multiple devices on your account and one is eligible for an upgrade, you can transfer upgrade eligibility to another line on your account whenupgrading your device in My Verizon. When you transfer eligibility from one line to another, the original line is no longer eligible for the upgrade discount.
    To transfer upgrade eligibility from one line to another line on your account:Go to the Upgrade Device page in My Verizon.
    Click Transfer Upgrade.
    Note: If the Transfer Upgrade link isn’t appearing, you may not be eligible to transfer an upgrade at this time
    Select the mobile number you want to upgrade. This will transfer upgrade eligibility to that line.
    Select the device you want to upgrade to and click Next.
    Follow the onscreen prompts to complete the remaining steps to upgrade your device.
    You’ve successfully transferred your upgrade eligibility to another line.

  • How do i convert my imovie trailer for the iphone 4 to other file formats?

    I'm due to make a comical presentation in 2 days, and i downloaded iMovie for the iphone 4, and would like to use the trailers created as part of the presentation.
    I'm on windows xp, and have sent the file to itunes, gone into the file sharing part, added it, saved it, and even synched the flipping thing and yet it wont even play in itunes??? thats driving me mad as it is??
    Not really bothered about that....My real main concern is wanting to play the movie file in an AVI/MOV/MP4 etc format, and have even downloaded various video conversion packages to try an convert and playback my results, but once again, and a few hours wasted, I find myself facing another brick wall.
    Is it even possible to playback the imovie trailers created in a more generic video format for others to see??
    I really do hope so!!!!
    If not, then apple, i want my £2.99 (about $5.50) back, coz that would be as pointless as a paper ashtray.
    I hope ive not had my pants pulled down and wasted my money an time on this.
    Please someone help me, or put me out of my misery.

    Actually, scrap that one girls. Ive figured it out. For those who have a similar prob, just make sure you have quicktime installed. plug ur iphone into ur pc as normal, and choose the camera an scanner options that appears auto on ur window. select the trailer u wish after the usual wizard talk through and then "ok" or "apply" or whatever the button is called. select your destination folder, and walaa. its all done, and converted into .MOV format.
    NOTE:  When saving ur trailer on ur phone, and it asks what file size, chose the Medium one, or it takes ages to open.....unless ur comp is super fast, and not like my craptop.

    Why can't I update my iPhone 4 to iOS 5.1? Every time I try it gets all the way done downloading it; however when it's processing the file the page tells me "There is a problem downloading the software for the iPhone. Network connection timed out. Make sure your network settings are correct and your network connection is active. or try again later." and next to the file it has err = -3259. I have tried this 17 times and it won't work. My iTunes is completely up to date. I have made sure that my connection is fine and I have tried turning my firewall off with no avail. This has happened to me before but usually the update will go through after 2-3 tries, never to this extent. I don't know what to do. Help!

    Error -3259 is a network timeout error, usually. This article might help:

  • Can I use my IMac OS 10.4 (old) to set up a wifi router, such as Airport Base, so I can have a wifi connection for the iPhone I plan to buy?  My IMac is not wifi capable.

    Can I use my several-years-old IMac OS 10.4 to set up a wireless router, such as Aiport Base, so I can have wifi for the iPhone I plan to buy.  My IMac is not wife capable. 

    Yes, Airport Express Base Station connected to your Mac by ethernet will work as a bridge. Or you can connect the AE directly to your router/modem by ethernet if it's a non-wi-fi router and it will act as a relay for that.

  • Can I use my Nationwide Messaging plan for the iPhone 4?

    I currently have a plan called Nationwide Messaging (you get unlimited texting and data for $35 a month, and minutes are 40 cents each) which works well for me since I rarely use my phone to talk. 
    All the iPhone FAQ says is that you need a Nationwide plan, which I have, and a data package, which is already included in my plan. So will this work for the iPhone?

    You'd have to upgrade to the smartphone version of that plan for $55/month since the $35 plan is for regular phones and it looks like they're are added requirements to be eligible for that one. 
    http://www.verizonwireless.com/b2c/splash/messagingplans.jsp
    "Who is eligible to sign up for the Nationwide Messaging Plan? 
    In order to establish your eligibility for the Blackberry or PDA Smartphone plan, please bring either a letter indicating that you are hearing impaired on appropriate letter head from your audiologist, hearing health professional, speech or language therapist/specialist, physician, surgeon, vocational rehabilitation agency counselor, teacher or credentialed therapist; or (ii) your membership card for the National Association of the Deaf, Hearing Loss of America, AG Bell, Association of Late Deafened Adults, Telecommunications for the Deaf, Inc or other similar group.
