Android First Aid: The Troubleshooting Playbook

The 60-Second Version

If you remember only a handful of things from this book, make it these. They handle the great majority of everyday phone troubles.

• When in doubt, restart the phone. Turning it off and back on fixes most problems all by itself.
• If one app misbehaves, close it and open it again before you worry about anything else.
• A phone that says storage is full needs some space cleared - old photos and unused apps are the usual culprits.
• Check the little icons at the top: they tell you if you are on Wi-Fi, on mobile data, or silenced.
• Never trust a pop-up that shouts virus detected. It is a trick. Do not call its number or install anything.

The Calm First Step: Restart

This is the most useful page in the book. A simple restart fixes more problems than any other trick, and it never harms a thing.

Think of a restart like a good night's sleep for the phone. It clears out little jams in its memory and lets everything start fresh. Your photos, messages, contacts, and apps are all untouched. Nothing is lost.

• Press and hold the side button (the long button on the right edge).
• On many Samsung phones you hold the side button and the volume-down button together to reach the power menu.
• When the menu appears, tap Restart, or tap Power off, wait, then turn it back on.
• Give it a minute to wake up fully before you test what was wrong.

When the Phone Is Frozen

Sometimes the screen locks up and nothing happens when you tap it. The normal restart menu will not appear. This is where a force-restart comes in.

A force-restart is like unplugging a stuck appliance and plugging it back in. It does not erase anything. It simply forces a phone that stopped listening to shut down and start over.

• On most Samsung Galaxy phones, press and hold the side button and volume-down button together for about ten seconds until the screen goes black and the logo appears.
• On a Google Pixel, press and hold the power button for about thirty seconds until it restarts.
• Keep holding even if it seems like nothing is happening - it can take several seconds.
• Let go once you see the maker's logo, then wait for it to start up on its own.

Closing a Frozen App

Often it is not the whole phone that is stuck - just one app. You can close that single app and leave everything else alone.

In that same recent-apps view, look for a Close all button, usually at the bottom or side. Tapping it clears every open app in one go. This is a gentle tidy-up and never deletes an app or its contents - it just stops them running for now.

• Open the recent-apps view. On many phones you swipe up from the very bottom of the screen and hold for a moment.
• On phones with three buttons at the bottom, tap the square or three-lines button on the left or right.
• You will see your open apps as a row of cards.
• Swipe the stuck app's card up and off the screen to close it. Then open it again fresh.

When an App Keeps Crashing

If one app quits over and over, closing it may not be enough. Two safe steps usually cure it: clearing its cache and forcing it to stop.

On that same app screen, tap Force stop, then confirm. This fully shuts the app down. Open it again afresh and it will often behave. If it still crashes, check for an update to that app in the Play Store, which we cover later in this book.

• Open Settings (the gear-shaped icon).
• Tap Apps, then tap the name of the troublesome app.
• Tap Storage, or Storage and cache.
• Tap Clear cache. This clears temporary junk only - it does not delete your account, photos, or messages.

When Storage Is Almost Full

A message saying storage is full or storage space running out means the phone's cupboard is packed. Once you clear a little room, the phone perks right back up.

When storage is nearly full, the phone has no elbow room to work. It can slow down, refuse to take photos, or stop apps from updating. Freeing up even a little space often fixes several problems at once. The next page shows the easiest ways to clear room.

• Open Settings.
• Tap Storage, or tap Battery and device care then Storage on many Samsung phones.
• You will see a bar showing how much space is used and how much is free.
• It also lists what is taking up the room - usually photos and videos, then apps.

Clearing Space Safely

Here are the safe, sensible ways to free up room, starting with the ones that reclaim the most space for the least effort.

Deleted photos sit in a Trash or Recently deleted folder for about thirty days, still taking up room. In Google Photos or your Gallery app, open that trash and empty it to reclaim the space right away.

• Photos and videos: if they back up to Google Photos, open that app, tap your picture, and look for Free up space to remove copies already saved online.
• Unused apps: in Settings, Apps, tap an app you never use and tap Uninstall. You can always reinstall it later at no cost.
• App cache: in Settings, Storage, some phones offer a one-tap clean-up of temporary junk. This is safe.

Wi-Fi or Mobile Data? How to Tell

A lot of confusion comes from not knowing which kind of internet the phone is using. The little icons at the top of the screen tell you at a glance.

Wi-Fi at home is usually faster and does not count against your monthly plan. Mobile data works when you are out and about but can cost more or run out. Knowing which you are on explains a lot - like why videos play fine at home but stutter in the car.

• A curved fan shape, like a slice of pie made of arcs, means Wi-Fi. You are on your home internet, which does not use up your phone plan.
• Bars or letters like 5G, LTE, or 4G mean mobile data - the internet that comes through your phone plan.
• If you see the Wi-Fi fan, you are on Wi-Fi. If you see 5G or LTE instead, you are on mobile data.
• Swipe down from the top of the screen to see these more clearly in the quick settings.

Reconnecting to Wi-Fi

If the phone forgot your home Wi-Fi, or pages will not load, reconnecting is quick. Here is how.

First, restart the phone - that alone often fixes it. If pages still will not open, unplug your internet box (the router) for thirty seconds, plug it back in, and wait two minutes for it to wake up. This restarts your home internet the same way we restart the phone.

• Open Settings and tap Connections then Wi-Fi (on Pixel, tap Network and internet then Wi-Fi).
• Make sure the Wi-Fi switch is on.
• Tap the name of your home network in the list.
• Type the password (also called the network key), which is often printed on a sticker on your internet box. Tap Connect.

No Sound or Stuck on Silent

If your phone went quiet - no ringtone, no alerts - it is almost always a setting, not a fault. These checks bring the sound back.

If only one app makes no sound, check the volume while that app is open - press volume-up while a video plays, for instance. Some apps have their own separate volume that is set apart from the ringer.

• Press the volume-up button on the side of the phone and watch the slider on the screen rise.
• Swipe down from the top and look for a Sound or Mute button in the quick settings. Tap it so it reads Sound, not Mute or Vibrate.
• Check for a small crescent-moon symbol at the top. That is Do Not Disturb, which silences alerts. Tap it off.
• In Settings, tap Sounds and vibration (or Sound) and make sure the ringtone volume is turned up.

A Dark or Sideways Screen

A screen that is too dim to read, or one that spins sideways when you do not want it to, are both quick fixes.

If the screen flips to sideways when you tilt the phone, swipe down from the top and look for a button called Auto rotate or Portrait. Tap it to lock the screen upright. Tap it again later if you do want it to rotate, such as for watching a video.

• Swipe down from the top of the screen to open quick settings.
• Find the brightness slider - a long bar, often with a small sun symbol - and slide it to the right.
• If the screen keeps dimming on its own, look for Adaptive brightness in Settings, Display, and you can turn it off to keep a steady level.

When the Phone Will Not Charge

A phone that will not charge is worrying, but the cause is usually a tired cable or a dusty port - not the phone itself. Check these in order.

If the battery ran all the way down to empty, the phone may show nothing at all for several minutes after you plug it in. Leave it connected for fifteen or twenty minutes, then check for the charging symbol before deciding anything is wrong.

• Try a different cable. Charging cables wear out from bending far more often than phones fail.
• Try a different wall plug (the adapter) and a different outlet, in case one is at fault.
• Look into the charging port at the bottom of the phone. Lint from pockets packs in there and blocks the connection.
• Gently clean the port with a wooden toothpick, with the phone turned off. Never use anything metal.

When Bluetooth Will Not Connect

Bluetooth is how your phone talks to hearing aids, headphones, a car, or a speaker without wires. When it will not connect, a few steps usually reunite them.

If a stubborn device will not connect, tap the small gear or the letter i next to its name, then tap Forget or Unpair. Now set the device into pairing mode again as its own instructions describe, and connect it fresh from the Bluetooth list. This clears up most sticking points.

• Make sure the other device - the headphones or hearing aids - is charged and turned on.
• On the phone, open Settings and tap Connections then Bluetooth (on Pixel, tap Connected devices).
• Check that Bluetooth is switched on.
• If the device is listed but will not connect, tap its name and choose Connect. If that fails, the next step often does the trick.

A Phone That Runs Hot or Slow

If the phone feels warm or has grown sluggish, it is usually working too hard or short on space. These steps cool it down and speed it up.

A phone often warms while charging, while playing video, or while using maps in the car. That is normal and nothing to fear. It is only worth attention if it grows uncomfortably hot for no reason, or stays hot long after you set it down.

• Close apps you are not using, as we did on the frozen-app page.
• Take it out of direct sun or off a warm surface and let it rest a few minutes.
• Restart the phone - a fresh start clears whatever was working it hard.
• Check that storage is not full, since a packed phone slows to a crawl (see the storage pages).

Using Safe Mode to Spot a Bad App

If the phone misbehaves and you suspect an app you installed is the cause, Safe Mode is a clever test. It starts the phone with only its built-in apps, so you can see if the trouble goes away.

In Safe Mode, apps you added yourself are switched off. If the problem disappears, an installed app was to blame - you can then remove apps you recently added, one at a time, to find the guilty one. To leave Safe Mode, simply restart the phone normally.

• Press and hold the power or side button until the power menu appears.
• Press and hold the Power off button on the screen for a moment.
• A prompt asks if you want to restart in Safe Mode. Tap OK.
• The phone restarts with the words Safe Mode shown in a corner.

Updating as a Fix

Sometimes the cure for a glitchy app or phone is simply an update. Updates carry repairs the makers have already worked out for you.

In Settings, tap Software update (on Pixel, tap System then Software update), then tap Download and install. If an update is offered, let it run while the phone is plugged in. These larger updates fix deeper problems and keep the phone safe.

• Open the Play Store (the colorful triangle icon).
• Tap your picture or initial in the top corner.
• Tap Manage apps and device.
• Tap Update all, or update just the troublesome app. Let it finish before you use the app again.

Fake Virus Pop-Ups

Sooner or later, while reading a web page, you may see an alarming pop-up shouting that your phone has a virus. Take a breath: it is a trick, and you can handle it calmly.

A page fills with flashing warnings - Virus detected, Your phone is infected, Call this number now, or Install this cleaner to fix it. It may beep or shake. It is designed to frighten you into calling a number or installing an app. None of it is real. Your phone is fine.

• Do not tap anything inside the pop-up, and do not call any number it shows.
• Do not install any cleaner, security, or repair app it suggests.
• Close the web page: open your recent-apps view and swipe the browser away, or close that browser tab.
• If it keeps coming back, restart the phone. That clears the page for good.

When a Backup and Reset Is the Answer

Once in a while, a phone is so tangled up that the kindest fix is a fresh start - a factory reset. Done in the right order, it is safe, but it is a last resort.

A factory reset wipes the phone clean and returns it to how it was new. When you sign back in with your Google account afterward, your photos, contacts, and apps come back from the backup. But anything not backed up is gone for good - which is why we back up first, and why this is a last resort.

• Make sure your photos are backed up in Google Photos (open it, tap your picture, check that Backup is on and finished).
• In Settings, tap Google then Backup, and make sure your contacts, apps, and settings are backed up.
• Write down your Google email and password on paper - you will need them to set the phone up again.
• Only once everything is safely backed up should you consider a reset.

When to Just Call Bill

You can fix a great deal yourself with this book. But part of using a phone wisely is knowing when to hand it to someone who does this all day. There is no shame in that - it is the smart move.

I come to your home here in Portage County, sit down with you and the phone, and fix it while you watch. No jargon, no rush, no talking down to you. Often it is a five-minute fix, and you learn something for next time.

• The screen stays black even after charging and a force-restart.
• The phone gets very hot, or the battery drains in a couple of hours.
• You are being asked to reset the phone or clear data and you are unsure.
• A pop-up frightened you and you are not certain you kept your information safe.
• You have tried the steps here and the trouble simply will not go away.
