How to confirm your model
Check the model number in your device settings, or bring it in and we will confirm the exact Samsung Galaxy S20 Plus before any work begins. If you are unsure which repair you need, our team will advise.
Before you book
- If the phone has had liquid exposure, a battery may not resolve everything and we check first.
- If the device is completely dead, we run a quick diagnosis before confirming the battery.
- If the screen or back is already lifting, the cell may be swollen, so book promptly and avoid charging it.
- If we discover water damage during your repair that affects the work, we will stop and let you know. A water damage diagnosis is applicable at the current fee, and we will confirm this with you before we proceed.
