How to Unfreeze a Frozen Samsung Galaxy A5 (2026 Guide)

The Samsung Galaxy A5 freezes when the system crashes or an app locks up the processor, leaving the touchscreen completely unresponsive. The most common cause is a rogue third-party app consuming too much RAM, though corrupted system cache and aging hardware also trigger freezes on this older device. A forced reboot (Volume Down + Power for 10 seconds) fixes the immediate freeze in most cases, but if your A5 freezes repeatedly, you will need to dig deeper.

This guide covers all Galaxy A5 variants — the 2015 (SM-A500), 2016 (SM-A510), and 2017 (SM-A520) models. The button combinations and recovery mode steps differ slightly between these versions, and those differences are noted in each section below.

What Causes a Galaxy A5 to Freeze

Before jumping into fixes, it helps to understand why the Galaxy A5 freezes in the first place. Here is a quick reference table for the most common causes and their symptoms.

Symptom	Likely Cause	Fix Section
Freezes during heavy app use	Insufficient RAM (2–3 GB)	Safe Mode, Clear Cache
Freezes randomly, any screen	Corrupted system cache	Wipe Cache Partition
Freezes after a software update	Incomplete or corrupted update files	Wipe Cache Partition, Factory Reset
Freezes and won’t respond to any buttons	Complete system crash or dead battery	Forced Reboot, Charge and Reboot
Freezes only when using specific app	Third-party app conflict	Safe Mode
Freezes with overheating	Battery degradation or charging IC failure	Hardware Inspection

Solution 1: Force Restart the Galaxy A5

A forced restart is the fastest way to unfreeze a Galaxy A5. It simulates disconnecting the battery, which clears the RAM and forces all processes to stop. No data is lost.

For Galaxy A5 (2017 — SM-A520):

Press and hold the Volume Down button and the Power button at the same time.
Keep both buttons held for 10 seconds or until the Samsung logo appears.
Release both buttons and let the phone boot normally.

For Galaxy A5 (2015 — SM-A500) and Galaxy A5 (2016 — SM-A510):

These models have a physical Home button. The forced restart combination is:

Press and hold the Volume Down button, the Home button, and the Power button simultaneously.
Hold all three buttons for 10–15 seconds until the screen goes black and the Samsung logo appears.
Release all buttons.

If the phone does not respond on the first attempt, try the same combination two or three more times. Sometimes the timing needs to be exact — press all buttons within the same second.

Solution 2: Charge the Phone and Force Restart

If your Galaxy A5 froze and now appears completely dead — no screen activity, no LED indicator, no vibration — the battery has likely drained to zero. When the battery dies during a system crash, the phone can get stuck in a state where it will not respond to the charger either.

Plug the original Samsung USB cable into a wall outlet charger (not a laptop USB port or wireless pad).
Connect the cable to the Galaxy A5.
Leave the phone connected for at least 15 minutes, even if no charging indicator appears on screen.
After 15 minutes, perform the forced restart from Solution 1 while the phone remains connected to the charger.
If you see the battery icon or the Samsung logo, the phone is recovering. Let it charge to at least 20% before unplugging.

If the phone still shows no signs of life after 30 minutes of charging, try a different cable and a different wall outlet. Damaged USB-C or Micro-USB cables are a common hidden cause — the Galaxy A5 2015/2016 models use Micro-USB while the 2017 model uses USB-C.

Solution 3: Boot Into Safe Mode

Safe Mode disables all third-party apps and runs only the stock Samsung software. If the Galaxy A5 works normally in Safe Mode without freezing, a third-party app is causing the problem.

To enter Safe Mode:

Press and hold the Power button until the power menu appears on screen.
Tap and hold the Power Off option for about 3 seconds.
A prompt will appear asking to restart in Safe Mode. Tap Restart (or OK on older firmware versions).
The phone will reboot and display “Safe mode” in the bottom-left corner of the screen.

If the phone is too frozen to reach the power menu:

Perform a forced restart (Solution 1).
As soon as the Samsung logo appears during boot-up, immediately press and hold the Volume Down button.
Keep holding Volume Down until the phone finishes booting. You should see “Safe mode” in the bottom-left corner.

Once in Safe Mode, use the phone normally for 15–30 minutes. If there are no freezes, the issue is a third-party app. The most common culprits on the Galaxy A5 include resource-heavy apps like Facebook, TikTok, and games that exceed the phone’s 2–3 GB RAM limit. Uninstall recently installed apps one at a time, restarting between each removal, until the freezing stops.

To exit Safe Mode, simply restart the phone normally.

Solution 4: Wipe the Cache Partition

The cache partition stores temporary system files that help apps launch faster. Over time — especially on a phone as old as the Galaxy A5 — these cached files become corrupted and cause freezing, lag, and app crashes. Wiping the cache partition deletes only temporary files. Your photos, contacts, messages, and apps are not affected.

Steps to wipe the cache partition:

Turn off the Galaxy A5 completely. If it is frozen, perform a forced restart first, then power it off.
Galaxy A5 2017: Press and hold Volume Up + Power simultaneously until the Samsung logo appears, then release the Power button but keep holding Volume Up until the recovery menu loads.
Galaxy A5 2015/2016: Press and hold Volume Up + Home + Power simultaneously until the recovery menu appears.
Use the Volume Down button to scroll to “Wipe cache partition” and press the Power button to select it.
Scroll to “Yes” and press Power to confirm.
Once the process completes, “Reboot system now” will be highlighted. Press Power to restart the phone.

The phone will take slightly longer to boot after a cache wipe as it rebuilds the temporary files. This is normal.

Solution 5: Check for Software Updates

Samsung ended official software support for all Galaxy A5 models by early 2021. The final Android versions are:

Galaxy A5 (2015): Android 6.0.1 Marshmallow
Galaxy A5 (2016): Android 7.0 Nougat
Galaxy A5 (2017): Android 8.0 Oreo

Since no new updates are coming, make sure your phone is at least running the final available version. Go to Settings → Software update → Download and install to check. If your phone is several versions behind, installing the latest available firmware can fix freezing issues caused by known bugs Samsung already patched before ending support.

Keep in mind that the Galaxy A5 no longer receives security patches, which means vulnerabilities discovered after 2021 remain unpatched. This is especially relevant if you notice freezing along with unusual battery drain or unexpected pop-ups, which could indicate malware. Consider installing a lightweight security app like Malwarebytes to scan for threats.

Solution 6: Factory Reset (Last Resort)

If none of the above solutions stop the freezing, a factory reset restores the phone to its original software state. This deletes everything on the phone — apps, photos, messages, accounts, and settings. Back up any important data before proceeding.

Factory reset via Settings (if the phone is responsive):

Go to Settings → General management → Reset → Factory data reset.
Scroll down and tap Reset.
Enter your PIN or password.
Tap Delete all to confirm.

Factory reset via Recovery Mode (if the phone is frozen or unresponsive):

Turn off the phone (force restart if needed, then power off).
Enter Recovery Mode using the button combination from Solution 4.
Use Volume Down to scroll to “Wipe data / factory reset” and press Power to select.
Scroll to “Yes — delete all user data” and press Power.
Once complete, select “Reboot system now” and press Power.

After the factory reset, the phone will boot to the initial setup screen. You will need to sign in with the Samsung account and Google account that were previously linked to the phone (this is Samsung’s Factory Reset Protection, or FRP).

When to Replace Your Galaxy A5

The Galaxy A5 was a solid mid-range phone when it launched, but as of 2026, even the newest 2017 model is over 8 years old. If your A5 freezes frequently despite a factory reset, the hardware itself may be failing. Common hardware issues on aging Galaxy A5 units include degraded NAND flash storage (which causes lag and freezes during read/write operations), worn-out batteries that cannot deliver stable voltage under load, and failing eMMC chips.

At this point, repair costs often exceed the phone’s value. Here are budget-friendly Samsung alternatives worth considering as upgrades in 2026:

Phone	Price Range	Key Upgrade Over A5	Software Support
Samsung Galaxy A16	$150–$200	6 GB RAM, Android 15, 5,000 mAh battery	6 years of updates
Samsung Galaxy A36	$250–$300	8 GB RAM, 120Hz AMOLED, 5G	7 years of updates
Samsung Galaxy A56	$400–$450	12 GB RAM, 50MP OIS camera, IP67	7 years of updates

Any of these phones will run circles around the Galaxy A5 in terms of performance, and their multi-year update commitments mean you will not face the same end-of-support situation for a long time.
