  1. Samsung Galaxy A3 (2017) Battery Replacement, Back cover replacement: step 1, image 1 of 1
    • Power off your phone before beginning disassembly.

    • Use an iOpener to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Samsung Galaxy A3 (2017) is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    • Use a small suction handle to create a gap at the bottom end of the Galaxy A3.

    • Insert an opening pick and slide the tip to the bottom left corner to cut the adhesive.

    • Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

    • Insert a new opening pick and start to cut the adhesive towards the bottom left side of the phone.

    • Use an opening pick to cut the adhesive on all sides of the phone. Leave one opening pick in every corner to prevent the adhesive from resealing.

    • Reuse an iOpener if the adhesive becomes hard to cut. During the removal process the back cover is under tension all the time and is likely to break if the adhesive isn't loose enough.

    • Insert an opening pick on the right side of the phone after you cut the adhesive on all sides. Flip it sideways until you can get a good grip on the back cover.

Conclusion

To reassemble your device, follow these instructions in reverse order.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape and press it firmly into place for 5-10 seconds.

For optimal performance and to avoid software sided errors, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.

Ho sostituito la batteria al mio Samsung a3, sul retro vi è resto di colla dovuta alla protezione. Immagino vada tolta per far contatto. Giusto?

Unfortunately I had no iOpener or proper spudgers at my disposal, so I found that a pretty thin and flat plastic (!) spatula and a hairdryer also worked. The spatula was about as wide as the battery and fit perfectly in the pocket near the bottom of the phone and the battery. A bit of gentle heat from the hairdryer and by using the spatula as a lever the battery popped out in no time.
