Walking around with a cracked screen isn't ideal and can potentially increase the risk of further damage to your Oppo A31. Our highly trained technicians at Express Service will inspect your smartphone for damage, test its functionality and replace your glass screen so it works like new after it's repaired. This typically takes only 20-30 minutes, so feel free to wait with us in-store or you may leave your Oppo A31 with us and come back later to collect it. Express Service uses only the best quality parts and precision equipment to ensure that your screen looks and feels as good as new after it's repaired. Your new display screen is covered by a 7-day warranty from the date of service.
