Samsung Galaxy A52 Charging Error Solution — Remove Resistor Fix
Next-gen repair diagram & secrets inside — discover a simple, technician-tested hardware trick that fixes the Samsung Galaxy A52 charging error. This guide shows the exact board area, the resistor to remove, required tools, and safety precautions — step by step.
Overview
Some Samsung Galaxy A52 units show "charging error" even when the charger and cable are good. After diagnostic tests, many technicians found a small resistor on the phone's sub charging board that, when faulty, prevents charging. Removing this resistor (as shown in the diagram) often restores charging functionality.
Quick Result Snapshot
Result: Device charges again after resistor removal in many cases (see bottom image in the provided diagram).
Tools & Materials
- ESD-safe work mat and wrist strap
- Hot air rework station (or fine-tip soldering iron for SMD)
- Fine tweezers (ESD safe)
- Flux, solder wick (optional), micro-solder paste
- Magnifier or microscope for board inspection
- Multimeter for pre/post testing
Step-by-step Repair
- Power off and remove battery (if removable) or ensure device is powered down.
- Open the phone and remove the back cover carefully following manufacturer steps (plastic pry tools recommended).
- Locate the charging sub-board (see highlighted area in image). Confirm match with your board layout.
- Use multimeter to check continuity and identify suspicious resistor (if comfortable doing diagnostics).
- Apply flux around the resistor. Heat with hot air / soldering iron and use tweezers to remove only the small resistor shown in the diagram.
- Clean flux residue, reassemble partially and test charging with a known-good cable/charger.
- If charging restores, reassemble fully. If not, restore resistor pads and continue diagnostics or consult a technician.
Why this works (short tech explanation)
That small resistor may act as a current/voltage sense path or part of a protective network. If it fails short/opens it can prevent the charging circuit from negotiating voltage/current. Removing it can bypass the faulty sensing element and allow normal charging in many instances.
Post-fix tests
- Measure voltage at the USB port while plugging in charger.
- Confirm battery is charging on screen (charging indicator) and via multimeter if accessible.
- Run a 10–15 minute stability test before full reassembly.
Troubleshooting — If it didn't work
- If still not charging: check charging port pins, replace port, inspect for corrosion or broken traces.
- If phone shows intermittent charging: test other nearby SMD components and test battery health.
- Restore resistor pads and seek professional diagnosis if unsure.
