The Samsung Galaxy S20 series has been out for more than 5 years, and cracked curved AMOLED screens and sharp drops in battery health are now the most common repairs. We support the full S20, S20+ and S20 Ultra range, and also offer Type-C port repair and system reinstall optimisation. We recommend backing up important data before repair. Done from 60 minutes.

The curved screen and older battery chemistry on the S20 series cause specific ageing problems in these devices, which are now 5+ years old. Below are the repairs we handle most often:
The curved AMOLED edges on the S20 series crack easily in drops and can lose touch response, and repairing them needs finer bonding work. We replace the curved screen assembly and test edge touch sensitivity.
After 5+ years of charge cycles, S20 series batteries have mostly lost a lot of capacity, causing sudden drops within half a day or sudden shutdowns. We offer battery replacement with a full charge and discharge test.
After repeated plugging, a Type-C port easily collects lint or its contact springs oxidise, causing poor charging contact. We clean the port first and replace the port flex module only once we confirm hardware damage.
The camera lens on the S20 series often cracks or the module comes loose in a drop, causing blurry images or failed focus. We offer camera module replacement and recalibration.
As Android versions update, a 5-year-old S20 carries a heavier processing and storage load and is prone to slowness and app crashes. We offer system clean-up, optimisation and storage management services.
The S20 series has IP68 water resistance, but the seals age with long use, raising the risk of water ingress. We offer emergency teardown, cleaning and rescue for water damage, with data preservation as the first goal.
Repairing an S20 that is 5 years old puts higher demands on parts supply and technician experience, so we have built the following core strengths for these older models:
Competitors' weakness: parts for older models are scarce, and some shops need long lead times. Our advantage: we keep S20 series curved screens and batteries in stock, with standard repairs done from 60 minutes.
Competitors' weakness: weak curved-screen bonding skills, leading to lifted edges or light leaks. Our advantage: technicians skilled in curved OLED bonding, with a tight, seamless fit after repair.
Competitors' weakness: older-model repairs come with only verbal promises and no recourse. Our advantage: every repair comes with a formal business invoice and written warranty certificate.
Competitors' weakness: novice apprentices who may not know older Samsung structures. Our advantage: technicians with 20+ years of Samsung device repair experience, familiar with the structure of different generations.
Competitors' weakness: parts for older models are expensive, so prices are easily raised. Our advantage: 100% free check first, then a fixed-price quote, with no extra charges.
Competitors' weakness: enquiries about older models often get read and ignored or brushed off. Our advantage: all-day WhatsApp answers; send a photo and we judge the situation on the spot and reserve stock parts.

Authoritative answers on Samsung S20 curved screens, battery ageing and water damage rescue
It depends on the repair item and the condition of the device. If only the screen or battery has aged, the repair costs far less than a new device and is still worthwhile; if the motherboard is damaged in several places, we honestly advise customers to weigh up the value of replacing the device.
Curved screens are more complex to manufacture and bond, so parts and labour generally cost slightly more than on flat-screen models, but we always quote before starting work, with no vague charges.
After a new battery is fitted, battery life improves noticeably to close to a brand-new device, though actual performance also depends on daily usage habits and background app drain.
No need. A hardware swap does not involve wiping the system or signing out of your Google account, and the photos, contacts and app data on the phone are all kept intact.
Switch it off at once and stop charging; do not try to turn it on. Bring it to our shop for an emergency teardown, cleaning and check as soon as possible; the sooner it's handled, the better the chance of saving the motherboard and data.

When your Samsung S20 needs a screen replacement, choosing the right repair shop matters too. Repair shops on the market vary widely in quality; some use aftermarket parts of uneven quality, or raise the price only after the repair, which is hard for customers to guard against.
Besides visible cracks, a screen fault can also be caused by the internal panel being deformed under pressure or a flex cable making poor contact. The exterior may look perfectly normal while touch or display is already abnormal. These "hidden" screen problems need professional instruments to diagnose accurately and are hard to tell apart by appearance alone.
Another risk of DIY repair is that the source of parts is hard to verify. Aftermarket parts bought online vary widely in quality, and some fail again soon after fitting, or even affect other functions that were working (such as water resistance, Face ID and fingerprint accuracy). Professional repair shops use original-quality specification parts and provide a written warranty, greatly reducing the risk of a device breaking again after repair.
What most customers care about before a repair is the price. We always follow the principle of "inspect first, quote after": the technician first runs a full check of your Samsung S20 with professional instruments, confirms the root cause and the parts to be replaced, and lists the cost breakdown clearly, starting work only after the customer confirms. If extra work turns up during the repair (such as a damaged flex cable or component), we tell you beforehand and get your consent, and never add a surprise charge after the repair is done, so customers know exactly where every dollar goes.
Our repair process has always followed the principle of "inspect first, quote after": the technician first runs a full check of the device with professional instruments, confirms the root cause of the fault and the parts to be replaced, and explains the repair plan and cost clearly to the customer, starting work only after confirmation, and never raising the price after the repair is done. Most repairs are done within 20 minutes to 1 hour, so customers can collect the same day without leaving the device for days.
