JTG Systems is the Niagara region's trusted OnePlus repair shop, serving St. Catharines, Niagara Falls, Welland, and the surrounding communities. Whether you need a flagship OnePlus 15 screen replacement, a battery swap for your Nord series, or a fix for your OnePlus Open foldable, we have you covered.
We verify fast charging capabilities (SuperVOOC / Warp Charge) after port repairs and use high-quality AMOLED panels to maintain that smooth 120Hz experience.
Because OnePlus parts are less common in the Niagara market, most components are sourced as needed with a 1–2 day lead time. Common screens, batteries, and charging ports for recent Nord and flagship models are usually available quickly.
Some older OnePlus models (8/9 Series) may develop a vertical green line on the display. We offer premium screen replacements to permanently resolve this known OLED defect.
Due to patent disputes, official sales were halted in some regions (e.g., Germany). However, we fully support imported devices with parts and service.
Precision repairs for all OnePlus flagships, foldables, and Nord models:
Fixing green lines (AMOLED defect), cracked glass, or black spots.
Battery draining fast, swollen battery, or Warp/SuperVOOC Charge issues.
Phone not charging rapidly, loose USB-C port, or cable play.
Broken rear glass replacement to restore structural integrity.
Liquid exposure cleaning, drying, and recovery assessment.
Stuck or unresponsive buttons, slider switch repair.
We test every OnePlus repair to verify Warp Charge and SuperVOOC high-current charging protocols function properly.
We ensure your device retains factory power stability and rapid thermal heat dissipation.
Every replacement screen, battery, and USB-C assembly is backed by our direct 90-day parts and labor warranty.
Bring your OnePlus in for a no-obligation inspection. We'll confirm the fault and explain your options.
Most OnePlus parts are ordered for your specific model, typically arriving within 1–2 business days.
We complete the repair and verify Warp/SuperVOOC charging, display response, and core functions.
Every repair is backed by a 90-day parts and labor warranty for peace of mind.
