Get your Samsung Galaxy S20 Ultra repaired anywhere in Jerusalem by Ofir Hershko. I arrive at your location and complete the repair inside my mobile service vehicle, ensuring your device never leaves your sight. Most S20 Ultra repairs are completed in under an hour.
The Samsung Galaxy S20 Ultra remains a powerful device, but its massive 6.9-inch curved display and heavy camera array make it vulnerable to specific hardware failures. Whether you are dealing with a shattered screen, a battery that no longer holds a charge, or the dreaded moisture detection error in the charging port, O-FIX provides a professional, on-site solution. Based in Jerusalem, Ofir Hershko brings a fully equipped mobile lab to your doorstep, providing high-quality parts and expert technical skill without the need for you to leave your home or send your device away to a shop. All work is performed in front of you, ensuring your data stays private and your hardware is handled with care.
The S20 Ultra features a massive camera hump that is highly susceptible to cracking if the phone is dropped. Even a hairline fracture can allow moisture to enter or cause lens flare in photos. I can replace the rear glass housing or just the camera lens cover to restore the device's water resistance and photographic clarity.
This model often suffers from a delicate charging port assembly. Over time, the port becomes loose, or you may receive a persistent 'moisture detected' warning that prevents wired charging even when the phone is dry. I replace the internal sub-board with a high-quality component to restore fast charging and data transfer capabilities.
The 120Hz AMOLED display on the S20 Ultra is prone to the 'Green Screen of Death' or white vertical lines caused by internal flex cable failure. Because the glass is curved, even a minor corner impact can shatter the digitizer. I offer several replacement tiers, including genuine Samsung Service Packs, to fix these display issues.
After several years of heavy use, the S20 Ultra’s 5,000mAh battery may begin to cycle rapidly or swell. If you notice the back cover lifting or the phone shutting down at 20%, it is time for a replacement. I provide genuine or re-celled original batteries that restore the device to its full factory capacity.
A common hardware quirk in the S20 series involves the signal cables that run near the charging port. If these are nudged or damaged during a DIY repair or a hard drop, you may experience 'No Service' or extremely weak cellular reception. I can reseat or replace these internal antenna connectors to fix signal drops.
Getting your S20 Ultra fixed is straightforward. First, contact me via WhatsApp or phone with your specific issue. I will provide a clear explanation of the repair and a quote. Once confirmed, I typically arrive at your Jerusalem location within 60 to 90 minutes. I perform the entire repair inside my mobile service vehicle; I do not enter your home, and your phone stays within your sight at all times. After the repair is complete, we will test all functions of the device—including the ultrasonic fingerprint sensor and camera—to ensure everything is working perfectly before I depart.
For the S20 Ultra, I provide several part tiers so you can choose the best fit for your needs. For screens, I offer genuine Samsung Service Packs (the highest quality available), refurbished originals, or quality aftermarket OLEDs. For batteries, you can choose between a genuine Samsung battery or a re-celled original. A re-celled battery uses the original Samsung controller board paired with a brand-new, high-capacity cell, ensuring the phone recognizes the part and maintains original performance. I will explain the technical differences between these options on-site so you can make an informed decision.
I provide a three-month warranty on all technical repairs and parts, including batteries and charging ports. However, please be aware that screen replacements and glass back replacements carry no warranty once the repair is completed and the device is handed back in working order.
I travel to all neighborhoods in Jerusalem and the immediate surrounding areas. I come directly to your home or office and perform the work in my vehicle.
Most Samsung Galaxy S20 Ultra repairs, such as screen or battery replacements, take between 30 to 60 minutes. I will give you a specific time estimate before I begin.
