下半年换手机要注意了？这4个雷区一定要避开，否则影响使用体验
2019年下半年已经到了，各大手机厂商都在发布新机，很多朋友也会在年末准备换手机，但是现在手机款式这么多，而且是5G手机也上市了，选好手机就变得更加困难了，而且并非每款手机都是全面发展的，最重要的是选择合适自己的，但是有几个雷区一定要尽量避免，下面我们就来一起看看要避免那些雷区吧。
1. 刘海屏
在2018年爆火的刘海屏，在2019年遭到了个到手机厂商的抛弃，只有苹果和华为即将发布的mate30 pro还是使用刘海屏，因为要使用3D结构光解锁的问题，所以在两款系列的手机还没有换成其他全面屏设计，其他手机款式都转为水滴屏、挖孔屏、升降全面屏。
2. 后置指纹
目前市场上主流的生物识别方式是指纹解锁或者是3D结构光，而3D结构光因为成本的原因没有在手机上普及。指纹解锁又分为屏幕指纹和电容式指纹，目前后置指纹解锁在2019年已经落伍了，消费者也不愿意为其买单，在2019年的手机中，屏下指纹是目前主流的设计，而且操作起来更加方便，只不过解锁速度比不上电容式解锁。
3. 不支持DC调光的OLED屏
尽管华为的大部分机型是lCD屏幕，但其他手机厂商大多使用的是OLED屏，虽然OlED屏色彩显示更加丰富，但OLED屏有一个先天缺陷，那就是频闪，长时间使用OLED屏手机会对眼睛产生一定的伤害，一般手机厂商都会加入DC调光防频闪功能，开启后还是对眼睛有一定的保护，所以买手机的时候一定要问下支不支持防频闪功能。
4.5G手机慎选单卡、NSA手机
5G正在紧张旗鼓的建设中，而5G手机也正在大规模的上市，华为、中兴已经发布了5G手机，其他手机厂商也即将发布，但是搭载骁龙X50基带的5G手机不支持5G双模，而且还是单卡单待的。目前只有搭载华为巴龙5000机型支持5G双模、双卡双待，高通的5G双模基带还要等到明年才会上市，今年买5G手机的话，只有华为比较好选择，不想买华为的话可以再等等。
小伙伴问我想出国旅游，但是英语不是很精通怎么办，像一般的英文翻译可以用浏览器来进行，但语音翻译就要用到录音转文字助手了，它可以帮你在线实时中英互译，不仅识别率准确，操作还简单便捷，翻译出来的英文还可以直接播放出来，简直就是出国旅游的必备神器，各大手机应用市场和百度搜索都可以找到哦。
所以下半年想换手机的朋友，尽量避开这4个雷区，否则会有一点影响你的体验感，那么小伙伴你现在认为哪款手机性价比高。
