Pakistan mein used mobile phones ki market bohot bari hai. Har koi naya phone khareedne ki salahiyat nahi rakhta, isliye log secondhand phones ko prefer karte hain. Lekin used mobile market mein scams aur fraud bohot aam ho chuke hain. Aksar shopkeepers ya online sellers kharab, repaired, ya bypass mobiles ko genuine keh kar bech dete hain.
Agar aap apne mehnat ke paise zaya nahi karna chahte, to ye detailed guide aapke liye hai. Is guide mein main aapko apna personal experience use karte hue 5 aasan aur behtareen steps bataunga jinse aap kisi bhi used mobile ko khareedne se pehle sirf 5 se 10 minutes mein mukammal check kar sakte hain.
1. Physical Condition Aur Screen Glass Testing
Sabse pehle mobile ko hath mein pakad kar uski physical halat ko dhyan se dekhein. Mobile ke side corners aur back panel ko ghaur se dekhein. Agar corners par scratches ya dents hain, to iska matlab hai phone gira hua hai.
- Glue aur Gaps Check Karein: Check karein ke back glass ya screen ke darmayan koi gap to nahi hai. Agar gap hai ya glue (gond) ke nishan hain, to phone open aur repaired hai.
- iPhone TrueTone Test: Agar aap iPhone le rahe hain, to Control Center mein brightness bar ko daba kar rakhein aur check karein ke TrueTone active hai ya nahi. Agar TrueTone missing hai, to 100% screen change ho chuki hai.
- Android LCD Shadow: Android phones mein white background open kar ke check karein ke screen par koi “Shadow” ya peela-pan to nahi hai. Copy screen ki brightness asli screen se hamesha kam hoti hai.
2. Hardware Diagnostic Secret Codes
Mobiles mein kuch secret code hote hain jinse aap screen, sensors, speaker, aur camera ek sath check kar sakte hain. Jab bhi used mobile lein, ye codes dialer mein lazmi dial karein:
- Samsung, Xiaomi aur OnePlus Codes: In mobiles mein dialer open karein aur
*#0*#dial karein (Samsung ke liye) ya settings mein “About Phone” mein ja kar “Kernel Version” par 4-5 baar click karein. Is se complete hardware testing panel open ho jayega. - Touch Testing: Screen par bani hui lines ko ungli se poora fill karein. Agar koi jagah khali reh jaye ya line break ho, to screen ka touch kharab hai.
- Proximity Sensor: Apne hath ko phone ke upar wale hisse (earpiece) ke paas le kar jayein. Agar screen green ho jaye ya vibrate kare, to sensor bilkul theek kaam kar raha hai.
3. Battery Health Aur Fast Charging Diagnostics
Used mobile lene ke baad sabse badi shikayat battery timing aur charging speed ki hoti hai. Isko check karne ka ek asan tarika ye hai:
- Battery Settings Check: iPhone mein Settings -> Battery -> Battery Health mein jayein. Agar health 80% se kam hai, to phone lene se gurez karein kyunki aapko jald hi battery badalni padegi.
- AccuBattery App (For Android): Android phones mein built-in battery health ka option nahi hota, isliye aap play store se “AccuBattery” app download kar ke real-time health aur battery capacity check kar sakte hain.
- Charging Port Test: Apna charger ya power bank sath lekar jayein. Phone ko charge par lagayein aur check karein ke fast charging support ho rahi hai ya nahi. Phone ko halka sa hila kar check karein ke port loose to nahi hai.
4. Camera Lenses Aur Microphones Verification
Aksar repair kiye hue phones ke camera ke andar dust (mitti) chali jati hai ya unka stabilizer kharab ho jata hai.
- Camera Focus & Zoom Test: Camera app open karein aur full zoom (10x ya 30x) kar ke check karein ke autofocus sahi kaam kar raha hai ya nahi. Agar focus hil raha hai ya image dhundli hai, to camera glass ya lens damaged hai.
- Microphone Test: Mobile mein 10 seconds ki video record karein aur bol kar check karein. Phir sound recorder app open kar ke alag se audio record karein. Is se aapko pata chalega ke top microphone (video recording ke liye) aur bottom microphone (calling ke liye) dono bilkul perfect kaam kar rahe hain.
5. PTA Status, IMEI Aur Patched/Bypass Phones (Most Important)
Pakistan ke mutabiq ye sabse zaroori step hai. Agar aapne non-PTA phone le liya, to aapki sim block ho jayegi aur aapke paise zaya ho jayenge.
- IMEI Verification: Mobile dialer se
*#06#dial karein. Screen par IMEI numbers show honge. Is IMEI ko Government ki official DVS (Device Verification System) website (dirbs.pta.gov.pk) par ya PTA ki official app par enter karein. Agar status “Approved” hai, tabhi phone khareedein. - Patched ya CPID Bypass: Android phones mein “Patched PTA” ya “CPID” ka dhoka bohot hota hai. Phone ko khareedne se pehle setting mein ja kar “Factory Reset” lazmi karein. Agar reset karne ke baad sim chalna band ho jaye, to iska matlab wo patched phone tha. Hamesha seller se reset ki guarantee lazmi lein.
Conclusion & Pro Buying Tip
Aakhir mein, hamesha koshish karein ke direct kisi unknown bande se phone lene ke bajaye kisi trusted shop se lein aur kam se kam 3 se 5 din ki check warranty lazmi lein. Agar koi online seller aapse pehle paise (advance payment) mange, to hamesha mana kar dein kyunki ye scams ka sabse bara tarika hai. Apni tasalli ke baad hi deal ko final karein.
