Getting to Know Your Samsung Galaxy A70: Key Features

Before we get down to business with spare parts, let's remember why the Galaxy A70 was so great (and still is!). This handset, launched in 2019, arrived to conquer the upper mid-range with compelling arguments:

• Screen: A spectacular 6.7-inch Super AMOLED Infinity-U display with FHD+ resolution (1080 x 2400 pixels). Ideal for watching series, gaming, or simply enjoying your social media!
• Processor: A capable Snapdragon 675 Octa-core (Dual 2.0GHz + Hexa 1.7GHz) that ensures good performance.
• RAM: 6GB or 8GB versions.
• Storage: 128GB internal, expandable with microSD up to 512GB! Plenty of space for your photos, videos, and apps.
• Cameras:
  • Triple rear: 32MP main sensor (f/1.7), an 8MP ultra-wide-angle (f/2.2), and a 5MP depth sensor (f/2.2).
  • Front: No less than 32MP (f/2.0) for stunning selfies!
• Battery: A generous 4500 mAh with 25W super-fast charging. To keep up with your pace.
• Operating System: Launched with Android 9 Pie and One UI 1.1, upgradeable to Android 11 with One UI 3.1.
• Design: An elegant body with a "3D Glasstic" finish (a plastic material that mimics glass, offering lightness and a premium look) in colours like Black, White, Blue, and Coral.
• Other: In-screen fingerprint sensor (optical), NFC, 3.5mm jack.

With these specs, it's no wonder you don't want to say goodbye to it!

Screens for Samsung Galaxy A70: Let the Brilliance Return!

One of the components that suffers the most is the screen. A silly drop, an unexpected knock... and crack! Broken glass, smudges, lines, or the touchscreen doesn't respond. But don't worry, there's a solution! For the Samsung Galaxy A70, there are several types of replacement screens:

• Original Samsung Screen (Super AMOLED): This is the ideal option if you're looking for the same quality as the factory-fitted screen. Vibrant colours, pure blacks, and the characteristic brightness of Super AMOLEDs. They tend to be the most expensive, but they guarantee perfect compatibility, including the functionality of the optical in-screen fingerprint sensor.
• Compatible OLED/AMOLED Screens: These are screens made by third parties using OLED or AMOLED technology. They offer image quality very similar to the original, with good colours and contrast. Many of these good quality OLED screens are also compatible with the A70's in-screen fingerprint sensor. It's important to check the product description to ensure this compatibility.
• INCELL Screens: This technology integrates the touch panel and the LCD into a single layer, resulting in thinner screens with good touch response. For the A70, if you find an Incell screen, make sure it's good quality. Some cheaper Incell versions (especially those based on TFT) might not be compatible with the fingerprint sensor or might not have the hole for it, as well as offering lower image quality than the original Super AMOLED.
• TFT (LCD) Screens: These are the most economical option. They use standard LCD technology. Although functional, the image quality (colours, contrast, viewing angles) will be noticeably inferior to your A70's original Super AMOLED. Furthermore, it's very likely that TFT screens will not be compatible with the in-screen fingerprint sensor, and power consumption may be higher.

Which screen to choose?

• Maximum quality and compatibility: Original Samsung Super AMOLED or a high-quality compatible OLED/AMOLED that specifies fingerprint sensor compatibility.
• Balance of quality and price: A good compatible OLED/AMOLED screen.
• Tight budget (assuming possible sacrifices): Incell (checking its features carefully) or TFT, being aware of the loss of image quality and, most likely, the fingerprint sensor function.

Most common screen problems on the Galaxy A70:

• Cracked or scratched glass: The most obvious.
• Touchscreen unresponsive or responding poorly (ghost touches): Could be due to broken glass, a damaged flex cable, or even software issues.
• Smudges or lines on the screen: Indicate damage to the LCD/OLED panel.
• Black screen but the phone turns on: Display failure or its connection.
• Dead pixels: Small dots that don't light up.
• Screen burn-in: On OLED screens, fixed elements can become "imprinted" over time (less common with normal use).

If the fingerprint sensor doesn't work after changing the screen, make sure the new screen is compatible, that it's properly connected, and try re-registering your fingerprints. Sometimes, a simple restart or a software update can resolve touch sensitivity issues.

Basic Guide: How to Change the Samsung Galaxy A70 Screen (Advanced Level)

Changing the screen is a delicate repair. If you don't have experience, we recommend going to a professional. If you dare, here are some general steps:

1. Preparation: Turn off the phone. You'll need specific tools (precision screwdrivers, plastic plectrums, suction cup, heat gun or hairdryer, new adhesive).
2. Heat and Open: The A70's back cover is glued on. Apply moderate heat around the edges to soften the adhesive. Use a suction cup and plectrums to carefully separate it.
3. Dismantle Internal Components: Remove the screws holding the mid-frame. Disconnect the battery (very important!) and the flex cables of the old screen and any other components that might be in the way.
4. Remove Old Screen: If the screen is badly broken, be careful with the glass shards. You might also need to apply heat to the front.
5. Install New Screen: Thoroughly clean the frame of adhesive residue. Connect the new screen and test that it works correctly (image, touch) before sealing it.
6. Reassemble: Apply the new adhesive, reconnect everything carefully, replace the screws, and seal the back cover, applying uniform pressure.

Warning! The A70's optical fingerprint sensor is sensitive. Incorrect installation or an incompatible screen can cause it to stop working.

Samsung Galaxy A70 Battery: Power for Ages! 🔋

The Samsung Galaxy A70 battery is model EB-BA705ABU, with a capacity of 4500 mAh. Over time and with charge cycles, all batteries degrade.

How to know if your A70's battery is faulty?

• It lasts very little time: If you used to get through the day and now you're looking for a charger by midday, it's a sign.
• It suddenly turns off: Even if it shows a charge percentage, the phone unexpectedly shuts down.
• It's swollen: If you notice the back cover bulging or the screen lifting at the edges, be careful! The battery could be swollen, which is dangerous. Replace it as soon as possible.
• It takes a long time to charge or doesn't charge to 100%.
• The phone gets excessively hot when charging or in use.

You can use the "Phone diagnostics" feature in the Samsung Members app to check the battery status.

OEM Batteries without a Logo: Are they reliable?

It's common to find "OEM" (Original Equipment Manufacturer) batteries for the A70. These batteries are made by companies that might also supply Samsung or that follow the same quality standards, but they are not sold directly under the Samsung brand for the spare parts market.

• What does OEM without a logo mean? Often, these batteries are identical to the originals in specifications and performance, but to avoid branding issues or because they are intended for repair channels, they don't carry the Samsung logo. They usually come in "loose packing" (simple packaging, not for retail sale).
• Are they like the originals? If they come from a trusted supplier, the quality can be very similar or identical to the original. They offer a good, more economical alternative to a battery bought directly from an official technical service with all the branded packaging.

Basic Guide: How to Change the Samsung Galaxy A70 Battery (Medium-Advanced Level)

1. Discharge the battery: For safety, it's advisable for the battery to be below 25%.
2. Turn off the phone and open the back cover: Follow the same steps as for changing the screen (heat, suction cup, plectrums).
3. Remove the mid-frame: Remove the screws holding it in place.
4. Disconnect the old battery: Using a plastic spudger, carefully disconnect the battery's flex cable from the motherboard.
5. Extract the old battery: It's usually stuck down with strong adhesive. You might need to apply a little isopropyl alcohol around the edges (being very careful not to damage other components!) or use a thin plastic card to gradually unstick it. Don't use metal tools or puncture it!
6. Place the new battery: Apply new double-sided adhesive if necessary. Connect the new battery.
7. Reassemble: Replace the mid-frame, the screws, and the back cover.

Galaxy A70 Back Covers: A Fresh Look! 🎨

The A70's "Glasstic" back cover, although resistant, can get scratched or broken. The good news is that changing it is relatively simple and gives your phone a fresh look!

Available Colours:

The Samsung Galaxy A70 was originally launched in the following colours:

• Black
• White
• Blue
• Coral

You can find replacement covers in these original colours or even in other finishes if you want to personalise it.

Basic Guide: How to Change the Samsung Galaxy A70 Back Cover (Easy-Medium Level)

1. Turn off the phone.
2. Apply heat: Using a heat gun (on a low setting) or a hairdryer, heat the edges of the back cover to soften the adhesive.
3. Use a suction cup: Place a suction cup near an edge and pull gently to create a small gap.
4. Insert a plectrum: Insert a thin plastic plectrum into the gap and slide it around the entire contour to cut the adhesive. You can use several plectrums to prevent it from sticking again.
5. Remove the old cover: Once unstuck, lift it carefully.
6. Clean off adhesive residue: Remove any residue from the phone's frame.
7. Place the new cover: Replacement covers usually come with their own adhesive. Remove the adhesive's protective film, align the cover properly, and press it firmly around all edges so it's well sealed.

Key Spare Parts for Your Samsung Galaxy A70 and A70s: The Essentials!

Besides screens and batteries, other components may need replacing. Here are some of the most sought-after:

1. Rear Camera for Samsung Galaxy A70s (and differences with A70):
   • The Samsung Galaxy A70s has a 64MP (f/1.8) main rear camera, while the Galaxy A70 has a 32MP (f/1.7) one. They are not directly interchangeable as a simple "upgrade" due to sensor and software differences.
   • If you need a replacement for the A70s rear camera, you must specifically look for that module. It solves problems like blurry photos, spots, the camera not focusing, or the camera app not opening.
   • For the Galaxy A70, the corresponding rear camera module is the 32MP+8MP+5MP one.
2. USB to Board FPC Connector for Samsung A70:
   • This component is crucial. It's the lower board (sub-board or charging module) that includes the USB-C port, and often also the main microphone and/or the headphone jack.
   • Problems it solves: If your A70 isn't charging, charging is intermittent, the computer doesn't recognise it, you have problems with the microphone during calls (if it's integrated into this board), or the audio jack isn't working.
   • It's usually a complete replacement part (the whole little board) and changing it involves opening the phone and disconnecting/connecting flex cables.
3. Integrated Fingerprint Sensor Flex for Samsung A70 and A70s:
   • Both models have an optical fingerprint sensor integrated under the screen. The spare part is usually the sensor itself with its flex cable.
   • Compatibility: There are fingerprint sensor flex replacements that are compatible with both the Galaxy A70 and A70s.
   • Problems it solves: If the fingerprint sensor doesn't recognise your finger, won't let you register new fingerprints, or simply doesn't work.
   • Important: Its correct functioning after a replacement can depend on the quality of the installed screen (if it has also been changed) and on correct calibration if necessary. Sometimes, simply deleting old fingerprints and re-registering them after the repair can solve problems. Replacing it is a delicate task as it's located under the screen.

Other Important Spare Parts for Your Galaxy A70:

At iLevante.com, in addition to the above, you can find a wide range of spare parts:

• Loudspeaker Buzzer (multimedia loudspeaker): If you can't hear ringtones, music, or videos.
• Earpiece Speaker (call speaker): If you can't hear well during calls.
• Microphone: If people can't hear you well during calls (it might be on the charging sub-board or a separate component).
• SIM Tray: If it's lost or damaged. Available in the phone's colours.
• Power and Volume Flex Cable: If the side buttons aren't working correctly.
• Rear Camera Lens: The protective glass for the rear cameras, which can get scratched or broken. Available with a bezel in the housing colours.
• Mid-Frame (Chassis): If the phone's body is badly damaged.
• Vibrator Motor: If the phone has stopped vibrating.
• Antenna Coaxial Cables: For signal problems.

Hardware Problems Beyond Screen and Battery

Your Galaxy A70 is a complex machine, and other components can fail:

• Charging Problems: Apart from the battery, the USB-C port can get damaged from use, dirt, or moisture. This can prevent charging or data transfer. The solution is usually to replace the charging sub-board.
• Audio Failures:
  • Main loudspeaker (multimedia): Low, distorted, or no sound when playing music or videos.
  • Earpiece (calls): Difficulty hearing the other person during calls.
  • Microphone: People can't hear you or hear you very quietly during calls or when recording audio.
  These problems can be due to the component itself or dirt in the grilles.
• Button Problems: The power or volume buttons can stop responding or get stuck due to wear and tear or knocks.
• Connectivity Failures: Problems with Wi-Fi, Bluetooth, or network signal can be due to faults in the internal antennas or their coaxial cables.
• Overheating: Although sometimes due to software, excessive and constant overheating could indicate a problem with the motherboard or battery.

Software Problems on the Galaxy A70: When It's Not All Hardware

Sometimes, your Galaxy A70 may show symptoms that seem like hardware issues, but the software is to blame! From a technical repair perspective, it's crucial to rule these out before opening the phone:

• Freezes and Extreme Slowness: After major updates (like the move to Android 11 that the A70 received), some users reported a drop in performance. This could be due to poor optimisation of the update or apps that are not fully compatible.
  • Technical Solution: Wipe the cache partition from recovery mode, check for apps consuming a lot of resources in the background, or as a last resort, a factory reset (after a backup).
• Abnormal Battery Drain: "Rogue" apps consuming power in the background, location services unnecessarily active, or even bugs in the operating system can cause the battery to drain faster than normal, mimicking a faulty battery.
  • Technical Diagnosis: Check battery usage statistics in Settings to identify culprit apps. Put rarely used apps into "deep sleep". Disable non-essential features.
• Ghost Touches or Unresponsive Screen: Sometimes, software problems or even a poorly fitted or poor-quality screen protector can cause issues with touch response.
  • Technical Solution: Restart the device. Try "Safe Mode" (disables third-party apps) to see if an app is the cause. Calibrate touch sensitivity if the option is available. Ensure there's no dirt or moisture on the screen.
• Fingerprint Sensor Problems: Apart from hardware faults with the sensor or screen incompatibility, sometimes the software can be the culprit.
  • Technical Solution: Delete all registered fingerprints and add them again. Make sure the phone's software is up to date. Clean the sensor area on the screen.
• Unexpected Restarts: If not due to overheating or a faulty battery, they can be caused by conflicting apps or serious system errors.
  • Technical Solution: Update all apps and the operating system. If it persists, a factory reset might be necessary.

From a technician's perspective, a "soft reset" (forced restart: Power + Volume Down) will always be attempted first, followed by checking for updates, trying Safe Mode, and, if necessary and the customer approves, a "hard reset" (factory reset) before proceeding to replace hardware components, unless physical damage is evident.
