Sell my Galaxy A21s

How much is a Galaxy A21s worth in the UK?

Galaxy A21s with 48MP quad camera and 5000mAh battery.

The price you get for your Galaxy A21s depends on its condition, storage size and which recycler you choose. Prices can vary by up to £100 for the same MacBook — GadgetRank compares all major UK recyclers in real time so you always see the best offer before you commit.

Samsung Galaxy phones are among the most traded devices in the UK. Prices are competitive and there are usually multiple recyclers actively buying your model. Condition and storage size are the two biggest factors affecting your offer.

The Galaxy A21s is available in 32GB, 64GB, 128GB storage options. Higher storage variants typically fetch more from recyclers, though the difference varies. Always compare prices for your specific storage size before committing.

What happens to your Galaxy A21s after you sell it?

Once your Galaxy A21s reaches the recycler, it goes through a multi-point inspection to verify its condition. If it matches what you selected, your payment is processed — most recyclers pay within 1-3 working days of receiving the device.

The vast majority of phones sold through recyclers are repaired, refurbished and resold — either in the UK or internationally. A small percentage that cannot be economically repaired are broken down for parts or responsibly recycled. Either way, your device stays out of landfill.

Selling your Galaxy A21s instead of leaving it in a drawer is one of the most straightforward things you can do to reduce electronic waste. The UK generates over 1.5 million tonnes of e-waste each year — and phones are among the most recoverable items in that stream.

Tips to get the best price for your Galaxy A21s

• Remove Samsung account before sending
• Factory reset the device
• Be honest about condition — recyclers inspect every device and will revise offers if it does not match
• Lock in your quote before posting — most recyclers hold their price for 14-30 days
• Sign out of Samsung account before sending — a locked device will be returned without payment

When is the best time to sell your Galaxy A21s?

Samsung Galaxy S series prices drop when Samsung announces the next generation, typically in January or February. Selling your Galaxy before the announcement window gives you the best price. Galaxy A series prices typically drop in spring when Samsung refreshes that lineup.

What condition should I select for my Galaxy A21s?

Excellent — no marks, scratches or dents. Screen is perfect. Battery health 80% or above. Looks as close to new as possible.

Good — light signs of use. Minor scratches that you have to look for. Fully functional. This is the most common condition for phones that have been used with a case.

Faulty — powers on but has a fault. Cracked screen, broken buttons, liquid damage or other issue. You still get paid, but less than working devices.

Being honest about condition is important. Recyclers inspect every device and will revise their offer if the condition does not match what you selected. This delays payment and can be frustrating. When in doubt, select the lower grade.

How fast does the Galaxy A21s lose value?

Samsung Galaxy phones typically lose 35-45% of their value in the first year. The Galaxy S series drops sharply when the next S series is announced in January or February. Galaxy A series phones depreciate more slowly but also recover less value — their lower launch price means smaller absolute drops.

A Galaxy A21s is worth the most right now, before the next Samsung announcement. Once Samsung reveals the next generation, recycler prices drop by 10-20% overnight. Selling before that window locks in the best possible price.

Can I sell a broken Galaxy A21s?

Yes. You can still get paid for a Galaxy A21s that has a fault. Recyclers buy broken phones to repair and resell, or to use for parts. Select Faulty when comparing prices to see offers for broken devices.

What recyclers will still buy in faulty condition:

• Cracked or broken screen
• Damaged back glass
• Battery issues — drains quickly or does not hold charge
• Buttons not working
• Camera problems
• Software faults

What recyclers typically will not buy:

• Liquid damage — most recyclers will not purchase water damaged devices
• Activation locked — if Samsung account is still active on the device, it cannot be resold. Remove your account before sending.
• Does not power on at all
• Missing major components

Always be upfront about the fault when getting a quote. Recyclers test every device on arrival and will revise their offer if the condition is worse than described.
