三星手機秘書長r220 I have a Samsung GSM mobile phone SG R220.我有一個三星的GSM移動電話秘書長r220 。 It has been working fine for last 6 years.它一直在努力的罰款，最後六年。 Last 3-4 days I was unable to get any signal on the phone.去年3-4天，我無法得到任何信號，在手機上。 I checked that the SIM card is working by using it on another phone and also verified that there is proper reception in my area.我查了該SIM卡的工作是用在另一個電話，也證實有適當的接待，在我區。 So I rightly suspected that the problem was with the phone itself.所以我懷疑是正確的，這個問題與手機本身。 I visited the Samsung service center only to be told that they will change the battery (which is also the back cover) which will “probably” improve the performance.我參觀了三星電子服務中心，只告訴他們將改變電池（這亦是封底） ，將“可能”性能的改善。 I grew suspicious because there was nothing wrong with the battery, it has been working fine for last 6 years.我生長的可疑，因為當時沒有什麼不妥的電池，它一直在努力的罰款，最後六年。 The battery worked without any issues even after being inactive and without charge for over a year!電池工作時不出現任何問題，甚至後，被停播，並沒有收取超過一年！ So I decided to hack my cell phone.所以我決定入侵我的手機。

I had the required screw-driver (special ones) to pry open the phone.我所要求的螺桿驅動程序（特別的） ，以刺探打開手機。 But before starting I wanted to clean the contacts of the antenna.但出發之前我想清潔接觸天線。 So I took the connecting pin of my multimeter connector (even a regular safety-pin will do fine) and started scratching the base of the antenna.因此，我採取了連接針我的萬用表連接器（甚至定期安全針將盡罰款） ，並開始刮的基礎上的天線。 In Calcutta nowadays it is very hot and humid, so I suspected that it could be damp related problem.在加爾各答現在是非常炎熱和潮濕，所以我懷疑這可能是潮濕的相關問題。 Immediately the signal strength increased by 3-4 bars and went near its maximum from zero previously.立即信號強度增加了3-4酒吧和到附近其最大從零以前。 So I went for more scratching.所以我到更多的划痕。 And surprisingly enough my cell-phone now has better reception than ever before.和足夠令人驚訝我的手機現在有更好的接待，比以往任何時候都。 All it needed was some scratching behind the ears ..所有它需要的是一些刮背後的耳朵.. err in the hole where the antenna is lodged.錯誤在該洞的地方天線的投訴。 While I am not sure if the same trick will work with every cell phone, especially the ones with hidden antennas, I think it is worth the effort to clean the antenna and its base as far as it is accessible for better reception.雖然我不知道如果同樣的把戲，將工作與每一個手機，特別是那些隱藏天線，我覺得這是值得努力的清潔天線及其基地而言，這是獲得更好的接待。
