Cell Phones

A cellular phone (also known as a mobile phone, cell phone, hand phone, or simply a phone) is a telephone that can make and receive telephone calls over a radio link while moving around a wide geographic area by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. Mobile phones that offer services such as text messaging, email, Internet access, business applications, gaming, photography and more general computing capabilities are referred to as smartphones.

Kyle,

One of the common problems we have is when users set their devices to fetch and keep all email and the devices become full.  The users complain that they no longer can receive email, the fix is to either change how much email they wish to keep on their device or to buy a device with more storage space.

Hmmm... I have Marshmallow on my S5 and the Now launcher isn't standard (which I take to mean is included by default).

Android System Updating
As the title indicates, I have done this before. It chills me everytime I update the OS on my phone, because one time I did this and I essentially had a bricked phone. Such is the price for being on the bleeding edge. Anyway, the morning of July 8, 2015, I received a push update of the OS on my Verizon Samsung Galaxy S5. It indicated that I needed a total of 800mb to do the update. I figured why not and went ahead with it. It was only after it had started, that I got nervous.

When I saw this screen...

2015-07-08-05.52.47.jpg... there was a similar screen when my device imploded, so I started to worry. It didn't help that according to one of my apps, I have 661 apps; I was hoping that this meant it wasn't optimizing built-in apps. Last time it counted all the way up to the second number and then reset and had a different number (fewer). But this time everything SEEMED to go smoothly. The system finished optimizing and rebooted. I was able to access most of my apps although some insisted that they didn't exist. I wasn't able to investigate any further, because at that time the device decided to reset. It hadn't warned me that it would take a long time on the Verizon screen after boot up, so I was a little worried when it had been booting on that screen for between 5 and 10 minutes. …

Optimizing apps normally happens when doing an OS update for major versions. This is especially true for the Lollipop update due to Google's major code refactoring.

How does one acquire that many apps...? My phone doesn't even have 100 apps and I use it for hours every day.

I use my phone for virtually everything. I also do beta testing for Android apps and am subscribed to the amazon app of the day and use the app of the day app (better than amazon).

It is a lot, especially for my 16gb S5.  I store a majority of my apps on my 64gb card.

I'm Dumb-phoned(ed)

Last week, I noticed this message when adding events to my Google Calendar:
SMS-article-3.pngOn June 27th (2015), Google is removing SMS as a notification option for Google Calendar events.  Their assumption is that enough people have smart phones and that they can use an app for notification.  Unfortunately, I have chosen a simpler life and still use a "dumb phone."  It has a real keyboard to make texting easier and has served my needs quite well for many years.

My Options


  • Upgrade to a new (smart) phone
  • Write some Python code that integrates Google Calendar with Google Voice
  • Configure my Google+ settings
  • Take advantage of Gmail
I will postpone the first option as long as possible.  I don't care what Google, or the tech industry in general, wants me to do.

I will hold off coding up a solution until I've explored all other work-arounds.

I tried to change the Google+ settings to use my cell phone as the notification target, but I needed the ability to send email from my phone in order to verify the address.  My cell phone account is simple enough that I don't have email - not a bad decision for a dumb phone, but one that prevents me from implementing this work-around.

Although Gmail isn't my primary email, I do use it.  After three tests, I have a work-around to my calendar SMS notification problem.

The Work-Around


1. Change your Google Calendar settings

Because of my work, where I am the IT goto guy for my department, I decided it was a necessity to have at least some experience with iPhones, iPads and Android devices.  This is mainly because our workplace does not have any policy restricting what devices can or cannot be on our network other than they have to have security software installed.   And I am then tasked with the job of having to troubleshoot ANY device, carried by someone in my department, that connects to the network (and they all use wifi at least).  There are some of my colleagues here that look like they are wearing a batman utility belt.  I know of at least one person who carries an iPhone, Android, Blackberry, WiFi AP, and a pager.  We all write, or try to write help documents for all these devices in regards to our network.  Such things as how to connect your device to our exchange server and how to configure your device to connect to our WiFi.  In order for these to documents to be at all helpful, we include screenshots of actually doing whatever we are describing (or sometimes I just make a movie).  To make those screenshots and to know what you are …

It really Depends on how much app's you have installed/Or running on your Android

Having Heavy draining Apps Running all day long(on both of the phones ) will shorten your batterys Life , and the power will not last as it was, Especially on Android

Being an android user , Some Apps Keep Auto Run on startup altough you didnt use them yet , Its quicker to run them since they are already executed on the background but it drains power : /, it is better to disable Auto start on the most Power-hungry ones

Benchmarks Are usually using Stock phones with no Apps on thems , and with no apps Android battery lasts longer:

http://cdn.bgr.com/2013/11/iphone-5s-5c-battery-life-test.jpg
Iphone has a more powerfull processor :

10563-2854-iPhone-6-Review003-l-1-.png
And in the underground Ios's are jail braked In order to Enable Customizations , that doesn't not equalize the equation ...So yeah Perhaps Carrying both is a must For It professionals

I wonder what kind of Applications Iphone User's have/Use especially in work ? are they the same as Android ?

I wondered the same.  My boss has an iPhone and needs to be able to get files of of our one they are on.  The only real option is the cloud.  He uses an FTP app as well, and with enough configuration you can use what amounts to a files app.

As an IT professional,  I have found one of the best apps for iOS is on the iPad only, called CI (computer inventory) from imobile3,  it does almost everything I need from an inventory app. There are others which do a better job of either querying the computers or storing the info (see my article on it here : http://www.experts-exchange.com/articles/18542/Finding-a-Computer-Inventory-Application-for-Use-with-Mobile-Devices.html).

If you are anything like me, you install many apps on your phone and have your life on it, sometimes literally.  When I bought my current phone, a Samsung Galaxy S5 from Verizon, they were only selling the versions with 16 GB internal.  I didn't realize this at the time, or I might have bought a different phone.  Anyway, I now had a phone with only 16 GB of internal memory, which translated to about 10.5 GB usable.  It helped to have a 64gb card, but I have been constantly trying to find space.  I am unused to getting the messages I currently get about not having enough space to install an app I want to try.
 
At work, the most common complaint we get from iPhone users about email, is that it isn't downloading their mail anymore.  This is an easy fix, because we know what the problem is, these are the users that have set their phones to download ALL emails. The fix is simply deleting their email account and redoing it but changing that setting to a couple of months instead.  I mention this because that is what I ended up doing on my phone. I had been looking in every crevice of the phone to try to get more space.  I finally decided to delete my email account (which I had set to retain all emails), and redo it with the setting to download the last  6 months instead of ALL.  I gained almost 500mb of space.

The next most common complaint is that they are running out of space because they have so many pictures on the phone.  To these people I always recommend Flickr.com. …

Nexus-4-Press-Shot1.jpgIf you’re having problems with your Nexus 4, you’ll want to take a look at this step-by-step troubleshooting guide that walks you through common issues and helps you solve them so that you can extend the life of your device.
 

Phone Won't Turn On

The phone will not turn on no matter what.
 

Dead/Bad Battery

Try charging the phone for several minutes, then turn it on again. If it still will not turn on after several minutes of charging, the battery might need to be replaced. See the iFixit battery installation guide here.
 

Bad Display

The phone may appear to be dead because the display screen has gone bad. If the phone has been dropped, exposed to water, otherwise damaged, or the screen has been cracked in any way, it is possible that the problem is the display. See the iFixit front display assembly guide here for a visual comparison.
 

Internal Problems

If none of these appear to be the problem, see the motherboard cover guide here and examine the motherboard for any physical defects.
 

Broken Back Panel

If the phone's back panel/screen is cracked or shattered, you may want to replace it.
 

Touch Screen is Unresponsive/Misconfigured

The screen is unresponsive to touch, or is inaccurately registering touch placement.
 

Internal Glitch/Malfunction

The problem is likely in the phone's software. Try restarting the phone. If this doesn't work, try a system or factory reset.
 

Physical Internal Problems

droid-charge.jpgIs your Samsung Droid battery constantly dying? SIM card not connecting to your network? Is the display scrambling? This guide will walk you through a list of common Droid headaches and how to quickly solve them.
 

Poor Battery Life

Your phone battery will not hold a charge very long, and dies within a few hours of being fully charged. You may be running an app that is taking up a lot of power to run, or displaying something on you phone that takes up a lot of battery life. To rectify this problem, it is a good idea to leave wifi, data, and Bluetooth off unless they are actively being used. Also, you should uninstall those applications that are taking up a lot of battery life. If this is true for most of your apps, then your battery may be too old and may need to be replaced. See the iFixit battery installation guide. If replacing it doesn't work, there is one last option you can try. You can install an extended battery. The assembly will go similarly to battery installation guide.
 

microSD Card Memory Full

When trying to save a file, your phone gives an "SD card memory full" error. Your memory card has too much data on it, and cannot fit any more. To fix this problem first try deleting some files you don't need from the card to free up space. If you still are getting this error, try replacing the SD card. See the iFixit microSD card installation guide.

Cracked Camera Lens

If you notice that your camera lens has a visible crack... To fix this issue, the camera must be replaced.
 

Pictures Have Better Quality on Other Devices

When taking pictures with your Samsung Galaxy Note 3, you notice there is a visible difference when viewing the image on your phone and viewing the image on another device. It is possible the display assembly is bad. If it is possibly that the display is bad then the display needs to be replaced.

Bad Battery

There are several problems your phone battery might have with different symptoms. The most obvious sign of a bad battery is that the cell phone shuts itself off. Other common symptoms include: the charge does not last, the battery is swollen, or there is excessive heat coming from your phone. If any of these are the case, your battery may need to be replaced. Here is a link to an iFixit replacement guide for the battery: HTC Droid DNA Battery Replacement
 

Bad Display

It is possible that the phone appears to be off because of a bad LCD Screen. You may need to replace the LCD screen.
 

Bad Motherboard

Another possible root of the problem could be that your phone's motherboard is fried. Your motherboard may need to be replaced. Here is an iFixit replacement guide for the motherboard: HTC Droid DNA Motherboard Replacement

Wi-Fi/Bluetooth Won't Connect or Won't Stay Connected

Your phone won't stay connected to Bluetooth devices or wireless networks.
 

Out of Date Software

Make sure you have the latest software update for your phone and try turning it off and back on again. These are two simple fixes that can potentially solve many common problems.
 

Hardware Failure

If the above fixes don't work, your phone may have a common hardware issue. An easy way to test this is the Squeeze Test. Gently squeeze your phone, between the camera lens and the volume buttons, if your Wi-Fi signal strength improves only to drop after you stop squeezing, your antenna is faulty. If this is the case then replacement of the antenna is required. View the iFixit replacement guide: HTC One X Antenna Replacement.
 

Phone Won't Charge

Your phone won't charge or charges very slowly.
 

Out of Date Software

Ensure you have the latest software update for your phone and try turning it off and back on again. These are two simple fixes that can potentially solve many common problems.

LG-G3.jpgHaving problems with your LG G3? Whether the front camera doesn’t work, the display doesn’t turn on, or your phone just doesn’t seem to be charging, you’ll be able to troubleshoot the issue with this step-by-step guide.
 

Phone doesn’t Charge

It takes longer than normal to charge, if at all, or phone doesn’t recognize when charger is connected.
 

Battery is Installed Incorrectly

The phone may not charge because the battery has been installed incorrectly. This could be the issue if your phone doesn’t charge, and if it doesn’t power on either. Let’s try removing the back cover, and reinstalling the battery. Here is an iFixit replacement guide: LG G3 Battery Replacement.
 

Battery is Bad

If the phone has been using the battery for a while, or if the user has used heavy applications on the phone it may cause the battery to heat up. If the user forgets the charging cable plugged in all night it will weaken the battery, especially if it was charged for a full night over multiple times. This is an easy enough fix. Start by removing the back cover. Here is an iFixit replacement guide: LG G3 Battery Replacement
 

Charging Port is Bad

Unfortunately, this requires either soldering or replacing the motherboard.
 

Display Not Turning On

The display does not turn on when the power button is pressed.
 

Battery is Not Charged

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

Nowadays, that little device you carry around in your pocket all day long can do way more than just make phone calls or send message, but believe it or not, there are some situations when, no matter how smart your phone is, it's exactly these two basic feature that the device in unable to do. 

How come?, you might wonder. Well, it's pretty simple: you have a carrier lock. Since calling and texting can be made only by using a SIM card, you can perform these operations just by using a SIM from the carrier you originally got your phone from. For example, if your phone is locked on AT&T, you cannot use T-Mobile's services on the same phone. 

But there's no need to worry, as there are a couple of methods through which you can get rid of this carrier lock, in order to use your phone in any network around the world. To be more specific, there are three methods: asking the carrier for the code, rooting and buying a code.

So, let's begin with the first one. In most cases, the carrier is obliged to give you a unlock code after your two-year contract is over. Still, some of them won't do this, since it implies losing a client. On the other side, if they are willing to give it, it won't be for cheap. 

Moving on - rooting. This technical procedure implies altering the phone's software in order to unlock it. Still, it's a very difficult process and, if it's not done correctly, you can end up with a totally damaged phone, which cannot be used anymore, that's why it should be …

The problem: You find yourself without your earphones or don't want to use your earphones (cordless), but you want to listen to media on your phone (music, books, etc.).  This is easy to do if you have a BlueTooth earpiece that supports listening to media on your phone.  In that case it has what is known as an a2dp profile, and will generally just work with no fiddling on your part.  BUT, if your bluetooth is older, or just does not have that feature, the cheaper ones tend not to, then you will need to use a workaround.

The Solution:  This is a fairly easy solution.  On my android phone, I downloaded an app called Mono Bluetooth.  When I tap the mono bluetooth icon to start the app I am presented with this screen:

Mono Bluetooth Router Screen
If your BT is connected just tap the "On" button and you will start hearing audio from your device.

Now, you may ask why would anyone use this?  Here is how I ended up discovering it and using it.  

I was waiting on line (yes, waiting on line) with my wife to see the Marc Chagall exhibit at the Jewish Museum in NYC.  The person in front of us was nice enough to tell us about a free audio guide you could download to your phone.  We downloaded the audio guide easily enough, but it was at that point that I realized I did not have my earphones on me.  It then occurred to me that I should be able to use my BT that I did have on me, to hear the sound, but that didn't work.  So I googled it and found this app as the easiest solution.

Migration of data from any other phone to HTC Android phone:

This area does not hold a lot to discuss about because the phone has a very good “Setup” application that helps transfer data (Contacts, Notes, Messages, etc.) from most of the popular makes via Bluetooth. I have tried it and it works as desired.

Wide range of supported phone models for data import
Migration of Contacts using a SIM card from HTC Android phone to Nokia:

Unfortunately there is no simple way to get your HTC contacts to a Nokia phone. The easiest way suggested is to copy all contacts to your SIM and then copy them back from the SIM to the phone. However, this approach has too many drawbacks:

Your SIM may only support a maximum of 250 to 300 contacts. This may generate the need to swap the SIM 3-4 times if you have more 750 or so contacts.

This article is in continuity with my previous article HTC Sensation Android Smartphone with ICS (Undocumented Features) : Part 1  Just in case you have not read it; it may be worthwhile to go through it before reading this one. Many terms which I will be using throughout this article may tend to be a bit difficult to comprehend, if you are a first time user of the Android Operating System (OS). Though I have written this article using ICS as the Operating System, it can be used as a general guideline for non-android cellphones too.

Battery:

The battery is one component in the mobile world where progress has been slow compared to other sectors. Yes, companies are making better batteries today. However with the introduction of smart phones, the demand for power has increased manifold in comparison to earlier basic phones, which were only used for calling and texting.

Phones were never meant to replace mobile computers but owing to the compactness and ease of carrying, they have indeed become today’s lightweight laptops (if not the extremely sophisticated ones). This ultimate switch-over in requirement has generated the need to supply batteries that should last as per the user’s expectations.

However, this power requirement always seems to be unmet, due to the extremely high use of smart phones. Moreover, there is always a trade-off between battery weight and its …
