Introduction
Use this guide to replace the back cover of your Samsung Galaxy A3 2017 smartphone.
Opening the Samsung Galaxy A3 will '''damage the waterproof sealing''' on the device. If you do not replace the adhesive seals, your phone will '''function normally''', but will '''loose its water-protection'''.
If needed, you can use a dropper or syringe to inject isopropyl alcohol (>97%) around the edges of the back cover to weaken the adhesive.
You’ll need '''replacement adhesive''' to reattach the back cover when reassembling the device.
Conclusion
To reassemble your device, follow these instructions in reverse order. When reassembling your phone apply new adhesive where it is necessary.
'''Secure the new back cover''' with pre-cut adhesive or double-sided adhesive tape.
After installing the rear cover, apply strong, steady pressure to your phone for several minutes to '''help the adhesive form a good bond.'''
