স্মার্টফোনের প্রযুক্তি নিয়মিত বদলাচ্ছে, আসছে নতুন নতুন ফিচার্স৷

নতুন ফোন হাতে নিতে এক, দু বছর অন্তর স্মার্টফোন বদলান অনেকেই৷

সময়ের সঙ্গে সঙ্গে ফোনে স্মার্টফোনে নানা রকম সমস্যাও দেখা দেয়৷

কিন্তু স্মার্টফোনের আয়ু কতদিন থাকে, এর কি এক্সপায়ারি ডেট হয়?

আসলে স্মার্টফোনের কোনও এক্সপায়ারি ডেট থাকে না৷

কিন্তু এমন কিছু কারণ থাকে যার জন্য স্মার্টফোন খারাপ হয়ে যায়৷

এমন কি, একদিনও ভাল ভাবে ব্যবহার না করলেও এই সমস্যা দেখা দিতে পারে৷

ব্র্যান্ডেড কোম্পানির স্মার্টফোন সাধারণত অনায়াসে বেশ কয়েক বছর চলে৷
