Alcatel presented the U5 back in February at MWC. Now, just days before the next big tech event IFA an upgrade of the device debuted. The Alcatel U5 HD retains the 5" IPS LCD, but ups the resolution to 720 x 1280 pixels. The Alcatel A3 XL on the other hand improves on the A3 with a larger screen and a more powerful battery. The Alcatel U5 HD comes with an 8MP primary camera (instead of the 5MP of its predecessor) while the selfie cam is 5 MP, upgraded from 2 MP. The battery is also slightly larger - 2,200 mAh vs. 2,050 mAh. The specs that haven't changed are the MediaTek MT6737...
Earlier this year, the Snapdragon 835 powered a mobile router that clocked 930Mbps download speed. The Sony Xperia XZ Premium is based on the same chipset and it reached 750Mbps in "real-world test conditions" - specifically EE's LTE network at Wembley Stadium in London. The test put the one of a kind screen to good use by streaming The Grand Tour in 4K HDR (from Amazon Prime). Other things that the Sony team tried out was to download high quality music for offline listening and downloading "humongous" files from Google Drive. They don't specify how they tested the upload, but the...

Any of the following could create this problem:
1. If your phone falls.
2. Contact with Water.
3. Dust buildup.
4. If a screw or clip is loose.
5. If wrong housing /fascia/ casing is used.
6. If for any reason the ground pins for keypads are not properly contacting or damaged.
7. Firmware bug or viral attack could cause this problem.
8. Damaged keypad could also create this situation.
9. Defect in the main board.
Take the phone to a certified technician or back to the source especially if the phone is still under the warranty period.
If the phone had a fall, this will create disalignment. Check for loose screws, catches, breakages or missing components. Carefully align the parts and you are back on track.
If the problem is created by dust, a little clean up of the keypad and the electronics will do the trick. If you cannot deal with it, send it in. Remember, if you are under warranty, any seal broken will void it.
If you want to do it yourself, restrict your operation to the visible areas immediately after the covers. Any attack on the chassis by an untrained hand might create more problems-earths may be displaced; Camera button or Bluetooth contact among others may be affected.
Swappable covers must be properly 'sited'. Care must be taken while unscrewing fascias and release catches with care where applicable, using an implement with a blunt blade around the edges, turning the blade now and then. Make sure that everything is reconnected properly and do not break any bits to avoid problems later.
Do not put painted housing on your phone because the paints may come off gradually, leaving debris on contact points between keypad and the next plate and this could lead to inability of keypad to execute commands later.
If the problem is on account of firmware bug/virus, debugging will suffice.While some mobile phones will require flashing to get going, remember to have your firmware updated regularly.
If the keypad is damaged, have it replaced and you are ready to go. Main board problems are better handled by service providers. Sometimes, phones with main board problems are recalled.
