We are given a list of negative reviews in Indonesian. The task is to summarize the reasons for the negative feedback. Let's break down each review and categorize the issues.

Step 1: Extract Complaints from Each Review

1. First Review:

   • "Barang sesuai harga, di foto ada tulisa bonus keyboard, ternyata di deskripsi gak ada keyboardnya"
     • Translation: "The item is according to the price, in the photo there is a bonus keyboard, it turns out the description does not have the keyboard."
     • Issue: False advertising (keyboard shown in photo but not in description/actual product).

2. Second Set of Reviews (multiple points in one entry):

   • "Keaslian:palsu" -> Authenticity: Fake
   • "Kegunaan:tidak bisa pakai barang blank" -> Usefulness: Cannot use the blank item (possibly a blank disc or similar)
   • "Kualitas:reputasi buruk" -> Quality: Bad reputation
   • "Saya pelanggan setia shopee tapi ketika saya beli tab ini Saya tidak mendapat barang sesuai dengan yang di harapkan, tabnya mati dan acc tidak lengkap internal hanya 512 itu juga ga bisa di pakai padahal yang dibeli 1 tb"
     • Translation: "I am a loyal Shopee customer but when I bought this tab I did not get the item as expected, the tab is dead and the internal storage is only 512 and it also cannot be used even though I bought 1 TB."
     • Issues:
       • Product not as described (1 TB storage but received 512 GB and not working).
       • Product is dead (not working).
   • "Fungsi:jangan beli di toko ini tukang tipu pesan tablet ram 16 GB yang di kirim 12 GB pesan memory 1 tera yg di kirim 500 GB harga mahal yang di kirim barang murahan"
     • Translation: "Function: Don't buy from this store, it's a scam. Ordered a tablet with 16 GB RAM but received 12 GB, ordered 1 TB memory but received 500 GB, expensive price but sent a cheap item."
     • Issues:
       • Scam (false specifications: RAM and storage downgrade).
       • Poor quality item (murah: cheap).
   • "Jelek bgttt kameranya, gak sesuai sama harga😭😭, nyesel belinyaa"
     • Translation: "The camera is very bad, not worth the price, regret buying."
     • Issues:
       • Poor camera quality.
       • Not worth the price.
   • "SIM card tidak terbaca, kualitas buruk"
     • Translation: "SIM card not detected, bad quality."
     • Issues:
       • Functionality problem (SIM not detected).
       • Bad quality.

3. Third Review:

   • "Kualitas:seperti bekas, kamera nya tergores, casing tdak sesuai sama barang type pad."
     • Translation: "Quality: Like used, camera has scratches, casing does not match the product type."
     • Issues:
       • Product seems used (like second-hand).
       • Camera has scratches.
       • Casing does not match the product type.

4. Fourth Set of Reviews:

   • "Jujur ga terlalu ekspektasi tinggi karna murah barangnya akan sebagus apa, cuma maksudnya ini bener2 loading lama banget 🙏🏻 maaf banget harus jujur"
     • Translation: "Honestly, I didn't have high expectations because the item is cheap, but this one is really slow, sorry I have to be honest."
     • Issue: Slow performance (long loading time).
   • "Keaslian:good\nKegunaan:berfungsi dengan baik\nKualitas:biasa \n\nMasih ada minus kalo nonton tiktok pada putih rambutnya"
     • Translation: "Authenticity: good, Usefulness: works well, Quality: average. There is a minus when watching TikTok, the white hair is visible (negative image quality)."
     • This one is mostly positive, but there's a minor issue with image quality on TikTok (white hair visible?).
     • However, note that the user marked it as average and has a complaint. We'll consider the negative part.
   • "Menurutku kurg bagus seh, kamera depan belakang hancoorrr padahal niat beli buat zoom ini kamera depannya besemut. Testimoni nya gambar2 n videonya bagus2 n foto/video testimoni tulisan cin* seperti testimoni dr luar di tranlate kn. Klo ada uang lebih mending beli yg agk diatsnya lagi. Warnanya cantik ungu."
     • Translation: "I think it's not good, the front and back cameras are bad, especially the front camera which is blurry. The testimonials (images and videos) look good, and the testimonial photos/videos have Chinese writing as if translated from outside. If you have extra money, it's better to buy something more expensive. The color is pretty, purple."
     • Issues:
       • Poor camera quality (blurry).
       • Testimonials are fake (with Chinese writing, possibly translated).
       • Not worth the price (recommends buying more expensive).
   • "Gak bisa pake sim card"
     • Translation: "Cannot use SIM card."
     • Issue: SIM card functionality problem.

Step 2: Categorize the Complaints

We can group the issues into categories:

1. False Advertising/Scam:

   • Keyboard shown in photo but not provided.
   • Tablet specifications (RAM, storage) not as described (16GB RAM vs 12GB, 1TB vs 500GB).
   • Fake testimonials (with Chinese writing, possibly translated).

2. Product Not Working/Defective:

   • Tablet is dead (won't turn on).
   • Blank item cannot be used.
   • SIM card not detected.
   • Cannot use SIM card.

3. Poor Quality:

   • Camera is bad (very bad, blurry, has scratches).
   • Used-like condition (scratches, casing mismatch).
   • Cheap quality item (murah) despite high price.

4. Performance Issues:

   • Slow loading (long loading time).
   • Image quality issues (white hair visible on TikTok).

5. Not Worth the Price:

   • Price is high but quality is low.
   • Regret buying, recommend buying more expensive item.

6. Mismatch Between Description and Actual Product:

   • Keyboard issue.
   • Storage and RAM not as described.
   • Casing does not match the product type.

Step 3: Summarize the Main Reasons for差评 (Negative Reviews)

The primary reasons for negative feedback are:

1. False Advertising: The products do not match the descriptions or images (e.g., missing keyboard, incorrect specifications for RAM and storage).
2. Product Defects: Many products are defective (dead tablet, SIM card not working, blank item unusable).
3. Poor Quality: Low-quality materials (camera issues, used-like condition, scratches).
4. Performance Problems: Slow operation and functionality issues (like TikTok image quality).
5. Price Mismatch: The product is not worth the price charged (overpriced for the quality received).
6. Fake Testimonials: Suspicions that positive reviews are fake (with Chinese text, possibly translated).

Final Summary in Chinese (since the original response was in Chinese)

主要差评原因总结如下：

1. 虚假宣传：商品与描述严重不符（如照片显示含键盘赠品但实际未提供；平板电脑标称16GB内存实收12GB、1TB存储实收500GB）。
2. 功能故障：产品无法正常使用（平板死机、空白存储设备失效、SIM卡无法识别等）。
3. 质量问题：商品疑似二手（摄像头有划痕、外壳与型号不匹配），或材质低劣（如“barang murahan”）。
4. 性能缺陷：设备运行卡顿（加载时间过长）、影像功能差（TikTok画面出现异常显示）。
5. 性价比失衡：用户认为价格虚高，普遍后悔购买并建议加价买更优产品。
6. 评价造假嫌疑：用户质疑好评图片含中文，疑似伪造外文评价翻译。

以上问题导致用户给出大量负面反馈，并警告他人谨慎购买。
