Smartphones can sometimes get hot when playing play games, listening to music, watching videos, or charging.

This is common and mostly caused when several Apps are running at once, or one App is using a lot of processor power.

Normally there is no need to worry about phones getting a warm while in use as the phone and battery can heat up to 120 Fahrenheit without damage.

However, when your phone becomes unbearably hot and you start having issue with your Apps, then there might be a problem. This might be due to faulty battery, too much charging, or a high workload.

To diagnose this, you can use apps like TempMonitor or Battery Temperature Guard (free) to monitor your device’s temperature.

Both can be downloaded from Google Play Store.

These apps should be able to tell you that your phone’s temp is within normal range.

Sometimes while typing long text or SMS messages you will get a message saying Converting to multimedia message. This won’t normally cause a problem, however some users do not want to send a MMS message.

There are a number of different settings to deal with this, however there isn’t really a way to prevent the phone from converting to an MMS. The reason for this is that any message over 480 characters cannot be sent as an SMS message. They must be sent as an MMS. The is a restriction of SMS messages in general, similar to the original limit of 160 characters.

What you can do however is ensure you get alerted when you have reached 480 characters. Then you can decide to send the message as an SMS and continue your conversation on a second message.

To check this setting is on, open your Message App and press Settings in the top right, then settings again, then More settings.

Then select Multimedia messages – Set restrictions and choose Warning. You will now be told when your message is being converted to MMS.

You can also change the settings for Creation mode which lets you restrict messages that go over a certain size. If you select Warning or Restricted, you should get further warnings when your message is really large and may not be handled by the network.

Smartphones that are always connected to the internet are great, but if you have a data plan that is capped each month, then you will want to keep an eye on how much data you are downloading. Fortunately there is a built in feature to monitor this.
