Dedika is a platform where you learn by doing: whether it's putting together a business proposal, becoming a nail technician, or using a new tool, for example. No matter your goal, the best content on the topic is already out there. But it's often in another language, expensive, scattered around, lacking practice activities, or part of a course that's too long for a busy schedule. That's why Dedika has its own approach: we find this material wherever it is, organise what makes sense for your goal, review it with support from experts who are available to answer questions, and create practical exercises so you learn by doing. You're the most important part of your journey and no one knows it better than you: choose the content and course length, whether you'll learn online or offline, and in whichever format suits you—video, text, audio, or summary. Your way, only with what makes sense for you. Here, every moment you dedicate is worth more and you get to what matters faster.

Our courses include a summary at the end of each chapter, which you can download as a PDF and print.

Applies controlled heat and opening tools to detach display assemblies from frames safely. Correct technique preserves frame integrity and reusable components.
Lesson 2 • Display Diagnostics and Fault Isolation
Uses visual inspection and software tools to distinguish panel, digitiser, and connector faults. Accurate fault isolation prevents unnecessary part replacement.
Lesson 3 • Display Replacement and Adhesive Application
Covers OCA glue, pre-cut adhesive strips, and frame tape application for secure display bonding. Proper adhesive application ensures waterproofing and structural integrity.
Lesson 4 • Display Technology Fundamentals
Compares LCD, AMOLED, and OLED panel technologies and their failure characteristics. Understanding panel differences guides correct replacement part selection.
Lesson 5 • Post-Replacement Calibration and Testing
Runs touch calibration, colour profile checks, and True Tone or ambient light sensor restoration. Ensures the replaced display meets original performance specifications.

Chapter 4See details

Battery Diagnosis and Replacement

Lesson 1 • Battery Extraction Techniques
Demonstrates pull-tab adhesive removal, isopropyl alcohol softening, and pry-free extraction methods. Safe extraction prevents puncture, fire, and motherboard damage.
Lesson 2 • Battery Replacement and Verification
Covers OEM vs. aftermarket battery selection, connector installation, and post-replacement calibration. Correct installation restores runtime and prevents premature failure.
Lesson 3 • Lithium Battery Chemistry and Safety
Explains lithium-ion and lithium-polymer cell chemistry, voltage ranges, and thermal runaway risks. Safety knowledge is mandatory before any battery handling begins.
Lesson 4 • Battery Disposal and Compliance
Addresses responsible disposal, recycling drop-off programmes, and transport regulations for lithium cells. Compliance protects the environment and avoids regulatory penalties.
Lesson 5 • Battery Health Assessment Methods
Uses built-in OS diagnostics and third-party tools to measure capacity, cycle count, and health percentage. Accurate assessment justifies replacement recommendations to customers.
