When to Seek Professional Help

If any issue continues after multiple attempts to fix it yourself, it might be hardware-related.
For example:

• Charging port or motherboard damage.
• Battery swelling.
• Screen touch IC failure.
• Water or humidity exposure inside the device.

Always visit an authorized repair center — not just any local shop — to maintain warranty and ensure original parts.

Preventive Care Tips

• Don’t overcharge or leave the phone on charge overnight.
• Backup data regularly.
